Abstract

Various embodiments of the present disclosure relate to a wearable electronic device including a speaker and a microphone, and more particularly, to a wearable electronic device worn on a user's ear. According to various embodiments of the present disclosure, there may be provided a wearable electronic device including: a first speaker emitting sound in a first frequency range; a second speaker emitting sound of a second frequency range including a frequency range higher than the first frequency range; a microphone; and a housing accommodating the first speaker, the second speaker, and the microphone therein, wherein the housing includes: an acoustic channel, which is a path through which sound emitted from the first speaker and the second speaker travels; and a recess for communicating the acoustic path with the outside of the housing, wherein the microphone is disposed at a position overlapping the first speaker in the first direction and is disposed at a position not overlapping the second speaker in the first direction when the recess is viewed from above.

Description

Electronic device comprising a speaker and a microphone

Technical Field

Various embodiments of the present disclosure relate to electronic devices including speakers and microphones.

Background

The electronic device may have at least one component associated with the sound effect mounted therein. The components related to sound effects may include, for example, a speaker and a microphone, and such components may be mounted inside a housing of an electronic device so as to have various formats and arrangement structures so as to correspond to external designs of the electronic device, which are variously designed.

Examples of electronic devices including speakers and microphones include wearable electronic devices that can be worn on a portion adjacent to a user's ear, such as an in-ear earphone (or headset) or a hearing aid. A microphone disposed within the housing of such a wearable electronic device may be provided to perform Active Noise Cancellation (ANC) functions. The ANC function may refer to a function for blocking noise by receiving a sound-related wave using a microphone, inverting the phase of the wave, and outputting the phase-inverted wave through a speaker. By performing the ANC function, noise generated inside or outside the wearable electronic device may be removed by destructive interference.

Disclosure of Invention

Technical problem

The wearable electronic device may have various acoustic and electronic components disposed in a single housing. When a wearable electronic device including a microphone in the acoustic path is installed and used in the user's ear, the microphone may collect sound waves emitted from the speaker or reflected within the ear in order to perform the ANC function. However, in the case of a conventional wearable electronic device, if a microphone is disposed in the path of sound output from a speaker that emits a high sound range, a peak signal may be input to the speaker-microphone response, and this may degrade ANC performance. Such peak signals in the high sound range may not operate in conjunction with implementing the ANC function in the relatively low sound range (e.g., a frequency band of 2kHz or less), resulting in problems such as howling.

In view of acoustic characteristics that vary according to a set relationship between an acoustic component including a speaker and a microphone and a set of channels (channels) connected to the speaker and the microphone, various embodiments of the present disclosure may provide a wearable electronic device with improved acoustic performance.

Additionally, the present disclosure may provide a wearable electronic device including a microphone mounting structure for reducing the effects of high sound range characteristics (e.g., peak signals) from a speaker, according to various embodiments.

Various embodiments of the present disclosure may provide a wearable electronic device, comprising: a first speaker configured to radiate sound in a first sound range in a first direction; a second speaker configured to radiate sound in a second sound range higher than the first sound range in a direction parallel to the first direction; a microphone; a housing configured to house a first speaker, a second speaker, and a microphone therein, the housing including an acoustic path extending in a first direction and configured to serve as a path through which sound radiated from the first speaker and the second speaker moves; and a recess configured to communicate the acoustic path with an outside of the housing, wherein the microphone is disposed in the acoustic path, and a sound receiver of the microphone is formed to face in a direction different from the first direction.

Advantageous effects

According to various embodiments of the present disclosure, when implementing ANC functionality by using a feedback microphone in conjunction with a wearable electronic device that includes multiple speakers, the relative arrangement between the speakers and the feedback microphone may be optimized, thereby reducing sound into the high sound range of the feedback microphone and improving ANC performance.

As for the reason that the wearable electronic device 300 has an asymmetric shape, ergonomic factors may be partially considered, but in terms of ensuring acoustic performance, an arrangement relationship between acoustic components and electronic components inside the case 310 may be prioritized.

The wearable electronic device 300 according to various embodiments of the present disclosure may correspond to a portion of a body, e.g., a device that can be worn on an ear or head. The wearable electronic device 300 may include, for example, an in-ear earphone (or in-ear headset), a hearing aid, etc., and may include various product groups in addition thereto, to which a speaker or microphone is mounted.

In the various drawings of the present disclosure, as an example of the wearable electronic device 300, a kernel-type in-ear earphone mounted on an external auditory meatus connected mainly from an auricle to an eardrum may be described as its object. However, it should be noted that the present disclosure is not limited thereto. According to another embodiment, although not shown in the figures, wearable electronic device 300 may target an open earphone mounted on the pinna.

Referring to (a) and (c) in fig. 3 together, the wearable electronic device 300 (e.g., 101 of fig. 1) may be integrated into the electronic device (e.g., 102 of fig. 1) or configured separately from the electronic device (e.g., 102 of fig. 1). Here, the electronic device (e.g., 102 in fig. 1) may correspond to various types of devices. Electronic devices (e.g., 102 of fig. 1) may include, for example, smart phones, mobile phones, navigation equipment, gaming machines, TVs, vehicle audio bodies, notebook computers, laptop computers, tablet computers, and Personal Media Players (PMPs), personal Digital Assistants (PDAs), portable communication devices, computer devices, portable multimedia devices, portable medical devices, cameras, wearable devices, or various electronic applications. The electronic device according to the embodiments disclosed herein is not limited to the above-described device.

The wearable electronic device 300 may be connected to an electronic device (e.g., 102 of fig. 1) either wired or wirelessly. In this case, in relation to the electronic device (e.g., 102 of fig. 1), the wearable electronic device 300 may function as an audio output interface (or sound output module (e.g., 155 of fig. 1)) configured to output a sound signal generated by the electronic device (e.g., 102 of fig. 1) to the outside. Additionally or alternatively, the wearable electronic device 300 disclosed herein may also be used as an audio input interface (or input module (e.g., 150 of fig. 1)) for receiving audio signals corresponding to sounds obtained from outside the electronic device (e.g., 102 of fig. 1).

Hereinafter, as an example, the wearable electronic device 300 may be provided separately from an electronic device (e.g., 102 of fig. 1). Thus, in the following embodiments, the electronic device (e.g., 102 of fig. 1) may also be referred to as an "external electronic device (e.g., 102 of fig. 1)", as it is provided separately from the wearable electronic device 300. Referring to (c) in fig. 3, the wearable electronic device 300 may be connected to an external electronic device (e.g., 102 of fig. 1) through a wire. In this case, the wearable electronic device 300 may communicate with an external electronic device using the cable 350. As an embodiment different from (a) in fig. 3, the wearable electronic device 300 may further include a connection part 340 for connecting the cable 350. According to one embodiment, one end of the cable 350 may be connected to the wearable electronic device 300, and the other end of the cable 350 may be connected to a connection terminal (not shown) formed in an external electronic device. Accordingly, the wearable electronic device 300 may be directly connected to an external electronic device.

In the case where the wearable electronic device 300 is wirelessly connected to an external electronic device (e.g., 102 of fig. 1) (e.g., (a) in fig. 3), the wearable electronic device 300 may communicate with the external electronic device via a network (e.g., a short-range wireless communication network or a long-range wireless communication network). The network may include, but is not limited to, a mobile or cellular network, a Local Area Network (LAN) (e.g., bluetooth communication), a Wireless Local Area Network (WLAN), a Wide Area Network (WAN), the internet, a Small Area Network (SAN), and the like.

The wearable electronic device 300 may include a communication module. The wearable electronic device 300 according to various embodiments may further include at least one of a power management module, a sensor module, a battery, and an antenna module. The communication module in an embodiment in which the wearable electronic device 300 is wirelessly connected to an external electronic device may correspond to a wireless communication module. In addition, in addition to the components according to the above-described embodiments, the wearable electronic device 300 according to various embodiments may further include an audio module (e.g., 170 of fig. 1) that may be integrated into the housing 310 of the wearable electronic device 300, thereby configuring a compact structure. The audio module (e.g., 170 of fig. 1) may include, for example, an audio input mixer (e.g., 220 of fig. 2), an analog-to-digital converter (ADC) (e.g., 230 of fig. 2), and an audio signal processor (e.g., 240 of fig. 2), a digital-to-analog converter (DAC) (e.g., 250 of fig. 2), and an audio output mixer (e.g., 260 of fig. 2). In the description of the elements of the audio module included in the wearable electronic device 300, a description overlapping with the embodiment of fig. 2 will be omitted.

According to one embodiment, the wearable electronic device 300 may not communicate with an external electronic device. In this case, the wearable electronic device 300 may be implemented to receive a signal corresponding to a sound acquired from the outside according to a self-operation (or control) of a component included in the wearable electronic device 300 and output the sound signal to the outside without being controlled by the external electronic device. For example, the wearable electronic device 300 may be a stand-alone electronic device that autonomously reproduces music or video without communicating with an external electronic device to output sound or receive and process the user's voice, respectively.

According to another embodiment, the wearable electronic device 300 may be in communication with and/or controlled by an external electronic device. The wearable electronic device 300 may be an interactive electronic device that pairs with an external electronic device such as a smart phone via a communication method such as bluetooth to convert data received from the external electronic device to output sound or receive voice of a user to transmit sound and voice to the external electronic device.

Fig. 4 is a schematic diagram illustrating a cross-section of an interior of a wearable electronic device 300 according to various embodiments of the disclosure.

Referring to fig. 4, the housing 310 may include a protrusion 320 that may be inserted into a user's ear. The protrusion 320 may be a portion coupled to one side of the housing 310 to protrude therefrom in one direction. The wearable electronic device 300 may be inserted and mounted in at least a portion of the body (external auditory canal or at least auricle of the body) using the protrusion 320. The protrusion 320 may further include an earplug mounted thereon, and may be brought into close contact with at least a portion of the body by the earplug (not shown) to be further stably supported by the at least a portion of the body.

Referring together to fig. 4, according to various embodiments, the housing 310 may include an acoustic path and a recess 321 for communicating the acoustic path with the outside. For example, the recess 321 may be an opening, small hole, gap, hole, etc. in the housing 310 that enables sound to be output to the outside of the housing 310.

According to various embodiments of the present disclosure, the wearable electronic device 300 may include a speaker 311 as an audio output interface. A speaker 311 may be provided to enable a user to hear various sound related information, such as playable music, playable multimedia, and playable records.

The wearable electronic device 300 may include a microphone 313 as an audio input interface. Microphone 313 may include, for example, a dynamic microphone, a capacitive microphone, or a piezoelectric microphone. The wearable electronic device 300 may receive an audio signal corresponding to sound acquired from the inside or outside of the wearable electronic device 300 through the microphone 313.

According to one embodiment, the microphone 313 may be a microphone for performing an Active Noise Cancellation (ANC) function (hereinafter, simply referred to as an "ANC microphone").

According to one embodiment, the microphone 313 may be disposed in a single housing 310 in parallel with the speaker 311. The outer wall structure of the case 310 may form an inner space having a predetermined size, and the microphone 313 and the speaker 311 may be disposed on the inner space of the case 310. According to one embodiment, the speaker 311 may be fitted into a speaker holder 311 'configured to accommodate the speaker, and the microphone 313 may be fitted into a microphone holder 313' configured to accommodate the microphone. According to one embodiment, the microphone 313 may also be configured to be coupled to and disposed on the microphone holder 313'. Since the volume of the microphone 313 is smaller than that of the speaker 311, the microphone 313 can be easily coupled and seated on the microphone holder 313'.

As shown in fig. 4, the housing 310 may include a narrower portion of the interior space for mounting the component at a location adjacent to a portion (e.g., a protrusion) insertable and mountable into at least a portion of the body (the external auditory canal or at least the auricle of the body), and may include a relatively wider portion of the interior space (S) for mounting the component at a location remote from a portion (e.g., a protrusion) insertable and mountable onto at least a portion of the body (the external auditory canal or at least the auricle of the body). In describing various embodiments of the present disclosure, among the components located in the interior space (S) of the housing 310, components located adjacent to a portion insertable and mountable on at least a portion of the body (e.g., the protrusion with the recess 321 formed thereon in fig. 4 or the grill portion with the recess 501 formed thereon in fig. 13) may be referred to as being "located outside of the wearable electronic device 300" (even though the components may be a portion of the wearable electronic device 300), and conversely, components located away from a portion insertable and mountable on at least a portion of the body (e.g., the protrusion 320 with the recess 321 formed thereon in fig. 4 or the grill portion with the recess 501 formed thereon in fig. 13) may be referred to as being "located inside of the wearable electronic device 300".

The housing 310 may include an acoustic path 312, the acoustic path 312 being configured to serve as a path for directing sound radiated from or output by a speaker. According to one embodiment, in the inner space (S) of the case 310, a portion other than a space for accommodating electronic components including the acoustic path, the speaker 311, and the microphone 313 may be filled with a specified material (e.g., resin). According to one embodiment, the inside of the housing 301 may be made waterproof by filling a portion other than a space for accommodating electronic components including the speaker 311 and the microphone 313 with a specified material (e.g., resin). According to one embodiment, a space for accommodating other electronic components including an audio signal processor (e.g., a processor), a board (e.g., a flexible printed circuit board, FPCB), and a battery 315 may be further formed in the inner space of the case 310. In fig. 4, the audio signal processor 314 and the battery 315 are shown as being mounted on a flat portion formed inside the housing 310, but the shape and arrangement of components inside the housing 310 are not necessarily limited thereto. According to another embodiment, the housing 310 and the remaining part inside the housing 310 may be formed substantially in a single body (e.g., a mold) except for a space for accommodating the acoustic path 312, the speaker holder 311', the microphone holder 313', and the electronic parts. The detailed arrangement of the components included in the housing 310 may vary according to embodiments.

The wearable electronic device 300 according to various embodiments of the present disclosure may provide a structure configured to ensure ANC performance by reducing sound in the high sound range of the microphone 313.

Fig. 5 is a schematic diagram illustrating a cross-section of a wearable electronic device 300 in which a speaker 400 and a microphone 430 are disposed, according to one embodiment of the present disclosure.

The wearable electronic device 300 may include speakers 400 (hereinafter, simply referred to as "multi-way speakers 400") configured to output sound in multiple directions. The multi-channel speaker 400 may include, for example, a plurality of speakers physically separated from one another. For example, the wearable electronic device 300 may include a first speaker 410 capable of outputting sound in a first sound range (e.g., a first frequency range) and a second speaker 420 capable of outputting sound in a second sound range (e.g., a second frequency range) that is higher than the first sound range. According to various embodiments, the wearable electronic device 300 may further include a third speaker capable of outputting sound between the first sound range and the second sound range, a fourth speaker capable of outputting sound other than audible frequencies (e.g., 20Hz-20 kHz), and the like in addition to the first speaker 410 and the second speaker 420 described above, but a description thereof will be omitted below. As an example, the wearable electronic device 300 may include a woofer configured to radiate sound (s 1) in a relatively low sound range as the first speaker 410, and a tweeter for sound (s 2) in a relatively high sound range as the second speaker 420. The first speaker 410 and the second speaker 420 described above may be implemented as dynamic drivers or balanced armature drivers, respectively. For example, the first speaker 410 may be configured as a dynamic driver and the second speaker 420 may be implemented using a balanced armature driver for each of the low sound range and the high sound range. According to one embodiment, the first speaker 410 configured as a dynamic driver may radiate sound through vibration of a membrane, and the second speaker 420 configured as a balanced armature driver may radiate sound through movement or vibration of a membrane (dialhragm) within a speaker housing through an open aperture (not shown). That is, according to one embodiment, the multi-channel speaker 400 may be manufactured as a hybrid speaker to which a dynamic driver and a balanced armature are applied together. In fig. 5, the sound (s 1) radiated through the first speaker 410 and the sound (s 2) radiated through the second speaker 420 may be simply indicated by arrows. According to one embodiment, the sound (s 1) radiated through the first speaker 410 may have a larger radiating area than the sound (s 2) radiated through the second speaker 420. The sound (s 2) radiated through the second speaker 420 may form a relatively narrow radiation area of the sound (s 2) as compared to the first speaker 410, and may have high linearity.

The wearable electronic device 300 may include a microphone or multiple microphones. For example, the wearable electronic device 300 may include a microphone configured to receive an audio signal corresponding to sound acquired from the inside of the housing 310 and a microphone configured to receive an audio signal corresponding to sound acquired from the outside of the housing 310. According to one embodiment, a microphone configured to receive an audio signal corresponding to a sound acquired from the inside of the case 310 may be provided in the inner space of the case 310, and a microphone configured to receive an audio signal corresponding to a sound acquired from the outside of the case 310 may be provided on the surface of the case 310. According to one embodiment, the microphone 430 disposed in the inner space of the housing 310 may be referred to as a feedforward microphone. The feed-back microphone may be used as an "active noise cancellation microphone (ANC) microphone" to perform ANC functions. In the following embodiments, for a microphone included in the wearable electronic device 300, a feedforward microphone will be mainly described. The wearable electronic device 300 may include a recess 321 configured to communicate the acoustic path 312 with the outside. Sound radiated from the multi-path speaker 400 may be transmitted to the outside (or hearing of a user) through the recess 321. According to one embodiment, the recess 321 may be formed in the grill 320'. The grill 320' may be formed to be seated on and fixed to a seating portion (e.g., a groove) 320″ of the protrusion 320.

According to various embodiments of the present disclosure, the wearable electronic device 300 including the multi-way speaker 400 may provide a "multi-way speaker and microphone arrangement" for ensuring ANC performance by reducing sound (s 2) into the high sound range of the microphone 430 disposed inside the housing 310.

According to various embodiments of the present disclosure, for a structure for ensuring ANC performance (e.g., a "structure between a multi-way speaker and a microphone"), according to one embodiment, the microphone 430 may be disposed in front of the first speaker 410 outputting sound (s 1) in the first sound range. According to another embodiment, the microphone 430 may be located in an acoustic path configured to serve as a path through which sound output from the first speaker 410 moves, so as to easily receive sound output from the first speaker 410 (s 1).

Referring to fig. 5, the wearable electronic device 300 according to one embodiment may include a first speaker 410 configured to output sound in a first sound range (s 1) and a second speaker 420 configured to output sound in a second sound range higher than the first sound range (s 2), the first speaker 410 and the second speaker 420 being provided in an inner space of the housing 310. According to one embodiment, the first speaker 410 may output sound in a first sound range in a first direction (e.g., the X-direction (or X-axis) of fig. 5) (s 1). In addition, the second speaker 420 may output sound in the second sound range in a direction parallel to the first direction (s 2). According to one embodiment, the size of the membrane (or open aperture) of the first speaker 410 (e.g., a woofer) configured to output sound in a relatively low sound range may be greater than the size of the membrane (or open aperture) of the second speaker 420 (e.g., a tweeter) configured to output sound in a relatively high sound range. Accordingly, the second speaker 420 having a relatively small size may be disposed outside the wearable electronic device 300 (e.g., near the protrusion 320 having the recess 321 formed thereon in fig. 4 or near the grill portion having the recess 501 formed thereon in fig. 13), and the first speaker 410 having a relatively large size may be disposed inside the wearable electronic device 300 (e.g., far from the protrusion 320 having the recess 321 formed thereon in fig. 4 or far from the grill portion having the recess 501 formed thereon in fig. 13). Thus, according to various embodiments of the present disclosure, the wearable electronic device 300 may be formed such that a distance from the first speaker 410 to the recess 321 for communicating the acoustic path 312 with the outside is formed longer than a distance from the second speaker 420 to the recess 321 for communicating the acoustic path 312 with the outside. That is, the distance between the first speaker 410 and the recess 321 may be longer than the distance between the second speaker 420 and the recess 321.

As described above, the wearable electronic device 300 may include the multi-speaker 400, for example, both the first speaker 410 and the second speaker 420 included in the multi-speaker may operate independently of each other. Accordingly, the sound radiated from the first speaker 410 and the second speaker 420 may also travel independently.

In the wearable electronic device 300 according to one embodiment of the present disclosure, the microphone 430 included in the housing 310 may be disposed on a path through which the sound (s 1) output from the first speaker 410 moves. According to one embodiment, the sound (s 1) output from the first speaker 410 may travel on the same acoustic path 312 as the sound (s 2) output from the second speaker 420. Considering that the sound (s 2) output from the second speaker 420 has high linearity (i.e., relatively low diffraction) due to its relatively high sound range, while the sound (s 1) output from the first speaker 410 has relatively high diffraction due to its relatively low sound range, the microphone 430 may not be disposed on the path through which the sound (s 2) output from the second speaker 420 travels, but on the sound path 312 through which the sound (s 1) output from the first speaker 410 travels.

Referring to fig. 5, the first speaker 410 may be disposed at a position relatively far from the recess 321 and the second speaker 420 may be disposed at a position relatively close to the recess 321 in the inner space (S) of the case 310 based on a direction toward the inside of the wearable electronic device 300. According to one embodiment, the second speaker 420 may be disposed between the recess 321 and the first speaker 410. In addition, similar to the second speaker 420, a microphone 430 may be disposed between the recess 321 and the first speaker 410. When the recess 321 is viewed from above, the microphone 430 may be disposed at a position where it overlaps the first speaker 410 in the first direction (e.g., the X-axis direction) and does not overlap the second speaker 420 in the first direction (e.g., the X-axis direction). In this case, "viewing the recess 321 from above" may mean that the wearable electronic device 300 is viewed as shown in (b) in fig. 3. Referring to fig. 3 (b) and 5 together, the microphone 430 may be disposed in the acoustic path 312 at a position where the microphone 430 overlaps the first speaker 410 and does not overlap the second speaker 420. "the microphone 430 overlaps the first speaker 410 and does not overlap the second speaker 420" may mean that the sound receiving aperture of the microphone 430 overlaps the membrane (or the open aperture) of the first speaker 410 but does not overlap the membrane (or the open aperture) of the second speaker 420. According to one embodiment, at least a portion of the housing of the microphone 430 may be disposed to overlap with the membrane (or the open hole) of the second speaker 420.

According to various embodiments, the first speaker 410 may include a 1 st-1 (or first) surface 410a facing the recess 321 and a 1 st-2 (or second) surface 410b facing in a direction opposite to the 1 st-1 st surface. The second speaker 420 may include a 2-1 (or first) surface 420a facing the recess 321 and a 2-2 (or second) surface 420b facing in a direction opposite to the 2-1 surface 420 a. The microphone 430 may include a first surface 430a on which a sound receiver is formed, and a second surface 430b on which the sound receiver is not formed and which faces in the opposite direction to the first surface 430 a.

According to various embodiments, the second speaker 420 and the microphone 430 may be disposed in the housing interior space between the recess 321 and the 1 st-1 surface 410a of the first speaker 410. In the wearable electronic device 300, the second speaker 420 and the microphone 430 may be disposed in a narrower space between the recess 321 and the first speaker 410, and electronic components other than the speaker and the microphone, for example, an audio signal processor (e.g., 314 of fig. 4) and a battery (e.g., 315 of fig. 4) may be disposed in a wider space in the direction of the 1-2 th surface 410b of the first speaker 410. According to one embodiment, the first speaker 410 may be supported by the housing 310 or a stand provided inside the housing, and may be connected to an audio signal processor provided on one side thereof (e.g., the 1 st-2 nd surface 410 b). The second speaker 420 and the microphone 430 may each be supported by a substrate, and may be connected to an audio signal processor located on the other side of the first speaker 410 using the substrate. For example, the second speaker 420 may be mounted on a first substrate 441 extending from one side of the first speaker 410, and the microphone 430 may be mounted on a second substrate 442 extending from the other side of the first speaker 410. According to one embodiment, the first and second substrates 441 and 442 may be formed of flexible circuit boards (FPCBs).

According to various embodiments, the microphone 430 may be disposed in the acoustic path 312 while mounted on a substrate (e.g., the second substrate 442). Referring to fig. 5, according to one embodiment, the microphone 430 may be floated while being supported in the hollow portion formed by the acoustic path 312 by only the substrate (e.g., the second substrate 442), but according to another embodiment, the microphone 430 may be provided to have one side supported on the inner surface 310' of the case 310 while being mounted on the substrate (e.g., the second substrate 442).

According to various embodiments, a sound receiver capable of receiving sound radiated from a speaker may be formed on the first surface 430a of the microphone 430. For example, the sound receiver in the embodiment of fig. 5 may be formed at a position corresponding to the arrow indicated by s 3. According to various embodiments of the present disclosure, the microphone 430 may be disposed in the acoustic path 312 such that the first surface 430a on which the sound receiver is formed faces the opposite side to the path through which the sound radiated from the second speaker 420 travels, thereby ensuring ANC performance. For example, when the direction in which sound radiated from the first speaker 410 travels is referred to as a first direction, the direction of sound radiated from the second speaker 420 may be parallel to the first direction. The internal structure of the wearable electronic device 300 as described above may be configured such that the first surface 430a (or the sound receiver) of the microphone faces in a direction different from the first direction, according to one embodiment, faces in a second direction (e.g., Y-axis direction) perpendicular to the first direction and opposite to a path through which the sound (s 2) radiated from the second speaker 420 moves. Accordingly, sound pickup of sound in a high sound range radiated from the second speaker 420 and introduced into the sound receiver of the microphone 430 can be reduced, thereby reducing, or preventing deterioration of ANC performance caused by peak components in the audio signal.

Fig. 6 is a graph illustrating improved ANC performance of a wearable electronic device according to an embodiment of the present disclosure. Fig. 6 (a) is a frequency response graph of a typical wearable electronic device 300, and fig. 6 (b) is a frequency response graph of a wearable electronic device (e.g., the wearable electronic device 300 of fig. 5) to which a "arrangement between multi-way speaker and microphone" for ensuring ANC performance is applied, according to various embodiments of the present disclosure. Here, the vertical axis may indicate the magnitude (dB) of the response, and the horizontal axis may indicate the frequency (Hz).

Referring to (a) and (b) in fig. 6 together, in a typical wearable electronic device to which an embodiment of the "arrangement between a multi-channel speaker and a microphone" for ensuring ANC performance is not applied, a peak component (P) can be detected in a high sound range. On the other hand, as indicated from the wearable electronic device to which the "arrangement between the multi-path speaker and the microphone" for ensuring ANC performance is applied, the peak component (P) is not detected, and thus the influence on the speaker at high frequencies can be reduced when the Active Noise Cancellation (ANC) function is implemented.

Fig. 7 is a schematic diagram illustrating a cross-section of a wearable electronic device 300 in which a multi-way speaker 400 and a microphone 430 are provided according to another embodiment of the present disclosure.

The wearable electronic device 300 according to the embodiment shown in fig. 7 may include substantially the same components as the wearable electronic device 300 according to the embodiment shown in fig. 5, and the components included in the wearable electronic device 300 according to the embodiment shown in fig. 7 may have substantially the same functions and arrangements as the components included in the wearable electronic device 300 according to the embodiment shown in fig. 5. Therefore, in the description of the embodiment of fig. 7, a description overlapping with the embodiment of fig. 5 will be omitted.

Referring to fig. 7, the wearable electronic device 300 may include a microphone 430, the microphone 430 including a first surface 430a having a sound receiver configured to receive sound and a second surface 430b facing in a direction opposite to the first surface 430 a. In the embodiment of fig. 7, the microphone 430 may be disposed in the acoustic path 312 between the recess 321 and the first speaker 410 such that the first surface 430a of the microphone 430 is inclined at a predetermined angle with respect to the acoustic path 312. In this case, the first surface 430a may be inclined such that the sound receiver of the microphone 430 is directed toward the first speaker 410. That is, the direction in which the first surface 430a (or the sound receiver) of the microphone 430 faces may be referred to as a third direction forming a predetermined angle (θ) of 0 degrees or more with respect to the first direction (e.g., X-axis direction) or the second direction (e.g., Y-axis) as shown in fig. 7. As shown in fig. 7, a microphone 430 tilted at an angle with respect to the sound path enables the microphone 430 to better receive sound signals in the low sound range and enables the direction of the sound receiver to be optimized such that the microphone 430 does not receive sound signals in the high sound range.

Fig. 8a is a schematic diagram illustrating a cross-section of a wearable electronic device 300 in which a multi-way speaker 400 and a microphone 430 are provided according to another embodiment of the present disclosure. Fig. 8b is a schematic diagram illustrating a cross-section of a wearable electronic device 300 in which a multi-way speaker 400 and a microphone 430 are provided according to another embodiment of the present disclosure. In the description of the embodiment of fig. 8a and 8b, a description overlapping with that of fig. 5 will be omitted.

Referring to fig. 8a and 8b, the housing 310 may further include an inner wall 450 separating the acoustic path 312. The acoustic path 312 may be divided into a first acoustic path 312a and a second acoustic path 312b by the inner wall 450, the first acoustic path 312a serving as a path through which sound radiated from the first speaker 410 moves, and the second acoustic path 312b serving as a path through which sound radiated from the second speaker 420 moves.

In this case, the microphone 430 may be disposed in the first acoustic path 312a serving as a path through which sound radiated from the first speaker 410 moves. According to the embodiment shown in fig. 8a, the microphone 430 may be disposed in the first acoustic path 312 such that the first surface 430a on which the sound receiver is formed faces in a direction opposite to a path through which sound radiated from the second speaker 420 moves. For example, the first surface 430a (or sound receiver) of the microphone 430 may face in a second direction (e.g., Y-axis direction).

According to the embodiment shown in fig. 8b, the microphone 430 may also be disposed in the first acoustic path 312a such that the second surface 430b on which the sound receiver is not formed is formed adjacent to the inner surface of the housing, and the first surface 430a faces a path through which sound radiated from the first speaker 410 moves. For example, the first surface 430a (or sound receiver) of the microphone 430 may face in a fourth direction (e.g., a direction opposite to the Y direction). When the inner wall 450 is formed in the acoustic path 312 as shown in fig. 8b, the influence of the sound radiated from the second speaker 420 can be reduced, whereby the direction in which the sound receiver of the microphone 430 faces can be more freely designed.

As shown in fig. 8a and 8b, by installing the inner wall 450 in the sound path and dividing it into a path through which the sound signal in the low sound range travels and a path through which the sound signal in the high sound range moves, the sound signal in the high sound range may not be received by the microphone 430.

Fig. 9 is a schematic diagram illustrating a cross-section of a wearable electronic device in which a multi-way speaker 400 and a microphone 430 are provided according to another embodiment of the present disclosure. In the description of the embodiment of fig. 9, a description overlapping with the embodiment of fig. 5 will be omitted.

In the embodiment shown in fig. 5, 7, 8a and 8b, the microphone 430 may be disposed closer to the recess 421 than the first speaker 410 and the second speaker 420. On the other hand, in the embodiment shown in fig. 9, the microphone 430 may be disposed closer to the recess 421 than the first speaker 410 while being disposed on the same level as the second speaker 420. Here, "part a is disposed on the same level as part B" may mean that with reference to a certain reference point, part a is disposed closer to the reference point than part B, or conversely, part B is disposed closer to the reference point than part a. In addition, "the component a is disposed on the same level as the component B" may mean that the component a is disposed in parallel with the component B in one direction (for example, the Y-axis direction in fig. 9). In addition, "part a is disposed on the same level as part B" may mean that at least a portion of part a is coplanar with (i.e., in the same plane as) at least a portion of part B; for example, at least a portion of part a and at least a portion of part B may lie on a line drawn parallel to the Y-axis direction shown in fig. 9 (corresponding to a plane extending into the page in the Z-axis direction perpendicular to both the X-axis direction and the Y-axis direction, i.e., a Y-Z plane). According to one embodiment, the wearable electronic device 300 may further include a recess into the housing 310 to form a space 312' between the acoustic path 312 and the first speaker 410. When the microphone 430 is located in the space 312', the microphone 430 may be disposed at a position overlapping the second speaker 420 in the second direction (e.g., Y-axis direction).

The microphone 430 in the above-described embodiment (the embodiment shown in fig. 5, 7, 8a and 8 b) is disposed in the acoustic path 312 adjacent to the protrusion 320 and formed by the inner surface 310' of the housing, whereas the microphone 430 in the embodiment shown in fig. 9 may be disposed in the inner space (S) of the housing 310 to be adjacent to the 1 st-1 surface 410a of the first speaker 410. In addition, the microphone 430 may include a first surface 430a on which the sound receiver is formed and a second surface 430b facing in a direction opposite to the first surface 430a, and the first surface 430a may be arranged to face the first speaker 410 such that sound (s 1) radiated from the first speaker 410 is better received by the microphone 430.

As shown in fig. 9, even when the microphone 430 is disposed at the same level as the second speaker 420, an arrangement that reduces, alleviates, or prevents the microphone 430 from receiving sound signals in a high sound range may be provided, and the direction of the sound receiver of the microphone 430 may also be optimized according to circumstances.

Fig. 10 is a graph showing improved high sound range characteristics according to the area of a sound path. In the graph of fig. 10, the area of the acoustic path may represent a cross-section of the acoustic path 312 of fig. 9 taken along line A-A', the vertical axis may represent the magnitude of the response (decibel sound pressure level (dBSPL)), and the horizontal axis may represent frequency (Hz). Referring to fig. 10, the size of the acoustic path is, for example, 9.3mm ² For example 8.5mm ² And e.g. 7.3mm ² May be represented by a solid line curve, a dotted line curve, and a dash-dot line curve, respectively.

For example, as shown in FIG. 10, the smaller the size of the acoustic path (9.3 mm ² ->8.5mm ² ->7.3mm ² ) The smaller the response amplitude in the mid-to-high sound range. As shown in fig. 9, compared with the embodiment described above in fig. 5 to 8b, the microphone 430, which is disposed in the space 312' formed in front of the 1 st-1 st surface 410a of the first speaker 410 and recessed in the housing and disposed in parallel with the second speaker 420 (overlapped in the second direction (Y-axis direction), results in a significantly widened area of the acoustic path 312, and can improve the response characteristics in the mid-high sound range.

According to one embodiment, as mentioned in the embodiments shown in fig. 7 and 9, sound quality and performance may also be improved by optimizing the direction in which the sound receiver of the microphone 430 faces and optimizing the size of the sound path, as mentioned by fig. 10.

According to various embodiments of the present disclosure, when implementing an ANC function using a feedforward microphone in a wearable electronic device including a multi-way speaker, an arrangement between the speaker and the feedforward microphone may be optimized to reduce sound into the high-sound range of the feedforward microphone, thereby improving ANC performance.

Fig. 11 is a schematic diagram illustrating a cross-section of a wearable electronic device in which a multi-way speaker 400 and a microphone 430 are provided according to another embodiment of the present disclosure. Fig. 12 illustrates a multi-way speaker 400 according to various embodiments.

In the description of the embodiment shown in fig. 11 and 12, a description overlapping with the embodiment of fig. 5 will be omitted.

In the embodiment shown in fig. 5, a multiplex speaker 400 including two speakers 410 and 420 physically separated from each other is provided, and in the embodiment shown in fig. 11 and 12, a multiplex speaker 400 including two speakers 410 and 420 physically not separated from each other may be provided. Hereinafter, the "multi-speaker 400 including the two speakers 410 and 420 that are not physically separated from each other" may be referred to as an "integrated multi-speaker 400".

According to various embodiments, the first speaker 410 and the second speaker 420 of the integrated multi-way speaker 400 may be provided in a single speaker body. For example, the integrated multi-channel speaker 400 may be formed by housing the second speaker 420 in the housing of the first speaker 410. Referring to fig. 12, an integrated multi-path speaker 400 according to one embodiment may include a first speaker 410 (e.g., a woofer) capable of outputting sound (s 1) in a first sound range and a second speaker 420 (e.g., a tweeter) capable of outputting sound (s 2) in a second sound range higher than the first sound range, the second speaker 420 being disposed within a body of the first speaker 410. In the case of the integrated multi-way speaker 400 shown in fig. 12, the second speaker 420 may be located at the center of the first speaker 410, and the second speaker 420 may be substantially surrounded by the first speaker 410. According to one embodiment, the first speaker 410 may include a 1 st-1 st surface 410a and a 1 st-2 nd surface 410b, and sound may be radiated through the 1 st-1 st surface 410a (s 1). The second speaker 420 may include a 2-1 st surface 420a and a 2-2 nd surface 420b, and may radiate sound through the 2-1 st surface 420a (s 2). The 1 st-1 st surface 410a of the first speaker 410 and the 2 nd-1 st surface 420a of the second speaker 420 may form substantially the same surface, e.g., the 1 st-1 st surface 410a of the first speaker 410 may surround the 2 nd-1 st surface 420a of the second speaker 420.

In this case, the first film 410c of the first speaker 410 may be formed at a position closer to the 1 st-2 nd surface 410b than to the 1 st-1 surface 410a, and the second film 420c of the second speaker 420 may be formed on the 2 nd-1 st surface 420 a. In the integrated multi-path speaker 400 structure, the sound (s 1) output from the first speaker 410 may radiate in the same direction (e.g., in the X-axis direction) as the sound (s 2) output from the second speaker 420. In this case, near the edge of one surface of the integrated multi-path speaker 400, the sound (s 1) output from the first speaker 410 may be radiated while having a larger radiation area than the sound (s 2) output from the second speaker 420.

The embodiments of integrated multi-channel speaker 400 may not necessarily be implemented solely in the form shown in the figures (e.g., fig. 11 and 12), and other various embodiments may also be applicable. For example, unlike the integrated multi-path speaker 400 shown in the drawings, the first speaker 410 may radiate sound through the second surface 400b of the speaker facing in the opposite direction to the X-axis direction, and the second speaker 420 may radiate sound through the first surface 410a of the speaker facing in the direction parallel to the X-axis direction. For example, sound (s 1) radiated from the first speaker 410 may also be radiated to the inside of the wearable electronic device 300 through the second surface 410b of the first speaker 410 to travel along the inner surface 310' of the housing 310 toward the sound path 312 and the recess 321.

According to various embodiments, the microphone 430 may be disposed at various positions capable of receiving the sound (s 1) radiated from the first speaker 410. The position of the microphone 430 in the embodiment shown in fig. 11 is shown as being disposed at the same position as in the embodiment shown in fig. 5, but is not necessarily limited thereto. For example, the positions of the microphones in the embodiments shown in fig. 7, 8a, 8b and 9 may also be applied to the positions of the microphones in the embodiment shown in fig. 11.

Fig. 13 is a schematic diagram illustrating a cross-section of a wearable electronic device with an audio module disposed therein, according to one embodiment of the disclosure. Fig. 14 is a schematic diagram illustrating a cross-section of a wearable electronic device with an audio module disposed therein according to another embodiment of the present disclosure.

Fig. 13 and 14 may provide a wearable electronic device 300 that includes an "audio module" formed by modular multi-way speaker 400 and microphone 430. In the embodiment shown in fig. 5-11, the multiplex speaker 400 and microphone 430 are provided as separate components in the housing 310 of the wearable electronic device 300, while the embodiment shown in fig. 13 and 14 shows that the multiplex speaker 400 and microphone 430 may be modular.

The audio module shown in fig. 13 and 14 may include a first speaker 410, a second speaker 420, and a microphone 430 disposed within an audio housing 500. According to another embodiment, the audio module may be formed such that the audio housing 500 and the grill portion having the recess 501 are integrated with each other. Referring to the embodiment shown in fig. 13 and 14, a seating structure for stably placing the grill portion on the protrusion of the wearable electronic device may be removed by integrally forming the grill portion with the audio housing 500. The resulting part may be fixed as a region of the acoustic path. When the region of the acoustic path is ensured, as described above in the frequency response variation graph of the area of the radiation hole according to fig. 10, the mid-to-high sound range characteristic of the speaker can be ensured. In addition, the wearable electronic device applying the modularized multi-way speaker 400 and the microphone 430 may reduce the size of the protrusions of the wearable electronic device in the same area, as compared to the wearable electronic device applying the non-modularized multi-way speaker 400 and the microphone 430, thereby improving wearing comfort.

The electronic device according to various embodiments of the present disclosure may be one of various types of electronic devices. The electronic device may include, for example, a portable communication device (e.g., a smart phone), a computer device, a portable multimedia device, a portable medical device, a camera, a wearable device, or a household appliance. According to the embodiments of the present disclosure, the electronic device is not limited to those described above.

It should be understood that the various embodiments of the disclosure and the terminology used therein are not intended to limit the technical features set forth herein to the particular embodiments, but rather include various modifications, equivalents or alternatives to the respective embodiments. For the description of the drawings, like reference numerals may be used to refer to like or related elements. It will be understood that a noun in the singular corresponding to a term may include one or more things unless the context clearly indicates otherwise. As used herein, each of the phrases such as "a or B", "at least one of a and B", "at least one of a or B", "A, B or C", "at least one of A, B and C", and "at least one of A, B or C" may include any or all possible combinations of items listed with a corresponding one of the plurality of phrases. As used herein, terms such as "1 st" and "2 nd" or "first" and "second" may be used to simply distinguish one element from another element and not to limit the element in other respects (e.g., importance or order). It will be understood that if the terms "operatively" or "communicatively" are used or the terms "operatively" or "communicatively" are not used, then if an element (e.g., a first element) is referred to as being "coupled to," "connected to," or "connected to" another element (e.g., a second element), it is intended that the element can be directly (e.g., wired) connected to, wireless connected to, or connected to the other element via a third element.

As used in connection with this disclosure, the term "module" may include units implemented in hardware, software, or firmware, and may be used interchangeably with other terms (e.g., "logic," "logic block," "portion," or "circuitry"). A module may be a single integrated component adapted to perform one or more functions or a minimal unit or portion of the single integrated component. For example, according to an embodiment, a module may be implemented in the form of an Application Specific Integrated Circuit (ASIC).

The various embodiments set forth herein may be implemented as software (e.g., program 140) comprising one or more instructions stored in a storage medium (e.g., internal memory 136 or external memory 138) readable by a machine (e.g., electronic device 101). For example, a processor (e.g., processor 120) of the machine (e.g., electronic device 101) may invoke and execute at least one instruction of the one or more instructions stored in the storage medium. This enables the machine to operate to perform at least one function in accordance with the at least one instruction invoked. The one or more instructions may include code generated by a compiler or code capable of being executed by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. Wherein the term "non-transitory" merely means that the storage medium is a tangible device and does not include a signal (e.g., electromagnetic waves), but the term does not distinguish between data being semi-permanently stored in the storage medium and data being temporarily stored in the storage medium.

According to embodiments, methods according to various embodiments of the present disclosure may be included and provided in a computer program product. The computer program product may be used as a product for conducting transactions between sellers and buyers. The computer program product may be distributed in the form of a machine-readable storage medium, such as a compact disk read only memory (CD-ROM), or may be distributed (e.g., downloaded or uploaded) online via an application store, such as a playstore (tm), or may be distributed (e.g., downloaded or uploaded) directly between two user devices, such as smartphones. At least some of the computer program product may be temporarily generated if published online, or at least some of the computer program product may be stored at least temporarily in a machine readable storage medium, such as the memory of a manufacturer's server, an application store's server, or a forwarding server.

According to various embodiments, each of the above-described components (e.g., a module or program) may include a single entity or multiple entities. According to various embodiments, one or more of the above-described components or operations may be omitted, or one or more other components or operations may be added. Alternatively or additionally, multiple components (e.g., modules or programs) may be integrated into a single component. In this case, the integrated component may still perform the one or more functions of each of the plurality of components in the same or similar manner as the corresponding one of the plurality of components performed the one or more functions prior to integration. According to various embodiments, operations performed by a module, a program, or another component may be performed sequentially, in parallel, repeatedly, or in a heuristic manner, or one or more of the operations may be performed in a different order or omitted, or one or more other operations may be added.

According to various embodiments, the sound range of a speaker refers to the frequency response range. In describing various embodiments of the present disclosure, the terms "sound range" and "frequency range" may be used interchangeably. For example, if the first speaker 410 is associated with a first sound range and the second speaker 420 is associated with a second sound range that is different from the first sound range, then the frequency response range of the first speaker 410 is different from the frequency response range of the second speaker 420. In an example, this means that no portion of the frequency response range of the first speaker 410 overlaps the frequency response range of the second speaker 420. In another example, the frequency response range of the first speaker 410 may partially overlap the frequency response range of the second speaker 420, however, the entire frequency response range of one speaker is not included in the frequency response range of the other speaker. In another example, one may say that one sound range includes one or more frequency values that are not included in another sound range. It will be appreciated that the frequency of the sound output by the speaker may be associated with the path of the sound as it moves after output.

According to various embodiments, the microphone 430 is disposed in a space between the recess 321 and the first speaker 410. In addition, the microphone 430 is disposed to avoid the acoustic path of the second speaker 420. For example, the microphone 430 may be disposed outside the acoustic path of the second speaker 420, or may be disposed such that relatively little audio signals (e.g., sound) emitted by the second speaker 420 reach the microphone 430. According to various embodiments, the acoustic path of second speaker 420 may be conceptually considered as a cone extending from second speaker 420 toward recess 321 (e.g., extending from an output region, membrane, diaphragm, audio source, etc. of second speaker 420). The size or expansion of the cone may correspond to the expansion or diffraction of the audio from the second speaker 420. In embodiments of the present disclosure, the microphone 430 may be disposed in the space between the recess 321 and the first speaker 410 so as to be external to the cone or substantially external to the cone (so as to reduce sound received from the second speaker 420). In an embodiment of the present disclosure, the microphone 430 may be arranged such that the sound receiver of the microphone 430 is positioned away from the cone when the cone extends from the second speaker 420. Of course, it will be appreciated that the acoustic path may not be exactly conical, or may correspond to different shapes, depending on the characteristics of the second speaker 420 and/or the structure of the space between the second speaker 420 and the recess 321.

Various embodiments of the present disclosure may provide a wearable electronic device, comprising: a first speaker configured to radiate sound in a first sound range; a second speaker configured to radiate sound in a second sound range higher than the first sound range; a microphone; and a housing configured to house the first speaker, the second speaker, and the microphone therein.
