Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

In the present disclosure, the use of directional terms such as "inner and outer" refers to the inner and outer of the corresponding component profiles, unless otherwise stated. Moreover, when the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated.

Referring to fig. 1, the present disclosure provides an earpiece device of an electronic apparatus including a pinhole-type sound outlet 110 and an audio module 200. The pinhole-type sound outlet 110 may be disposed on the housing 100 of the electronic device, and the audio module 200 may be disposed inside the housing 100 of the electronic device; the audio module 200 may include a sound emitting element 210 and a sound guide channel 220, and both ends of the sound guide channel 220 are connected to the sound emitting element 210 and the pinhole type sound outlet 110, respectively, to transmit sound to the outside. Thus, when the handset device is in operation, the received electrical signal provides the sound generating element 210 with an operating voltage to make it operate to generate sound, and the sound passes through the sound guiding channel 220, is transmitted to the pinhole sound outlet 110, and is finally transmitted from the pinhole sound outlet 110 to the outside to push the outside air to generate sound. It should be noted that, in the embodiment of the present disclosure, the sound guide channel 220 can transmit sound, and can adjust and optimize the sound emitted by the sound emitting element 210, so that the sound quality meets the requirement of the earpiece device. For example, the sound guiding channel 220 may be configured as a sound guiding tube, wherein the longer the sound guiding tube, the larger the diameter, the slower the air column inside the tube body vibrates, and the lower the frequency, and conversely, the faster the air column vibrates, the higher the frequency, and the tone changes when the frequency changes, so that the sound can be adjusted and optimized.

Through the technical scheme, the earphone device of the electronic equipment provided by the disclosure is provided with the sound outlet with the pinhole type design, the pinhole type sound outlet 110 is simple in structure and convenient to manufacture, the area of the sound outlet is greatly reduced while the requirement of the user on the tone quality is ensured, the personalized design is attractive, fashionable and practical, and the high-tech experience feeling can be brought to the user. In addition, the audio module 200 corresponding to the connection with the pinhole-type sound outlet 110 may also have a smaller volume, so that the space occupation thereof inside the housing 100 can be effectively reduced.

Further, referring to fig. 2, the pinhole sound outlet 110 may include two pinhole sound outlets spaced apart from each other on the housing 100, and accordingly, the audio module may include a low frequency module 201 and a medium frequency module 202 respectively communicating with the two pinhole sound outlets 110. By arranging the two pinhole type sound outlets 110 and respectively connecting the low-frequency module 201 and the intermediate-frequency module 202, the tone quality restoration effects of the low frequency and the intermediate frequency of the earphone device can be better ensured, so that the definition and the fidelity effect of the tone quality are ensured. The frequency range of the low frequency module 201 may be 100Hz to 1500Hz, and the frequency range of the intermediate frequency module 202 may be 1500Hz to 6000 Hz. That is, the low frequency module 201 may receive the voice signal with the voice signal frequency point centered in the range of 100Hz-1500Hz, and the intermediate frequency module 202 may receive the voice signal with the voice signal frequency point centered in the range of 1500Hz-6000 Hz.

In the embodiments provided by the present disclosure, the diameter of the pinhole acoustic hole 110 may be 0.6mm to 1.0mm, for example, the diameter of the pinhole acoustic hole 110 may preferably be 0.8 mm. Of course, the diameter of the pinhole type sound outlet 110 can be reasonably designed and selected by those skilled in the art according to actual needs, and the disclosure is not limited thereto. As such, compared to the conventional earpiece sound outlet, the pinhole-type sound outlet 110 of the earpiece device provided by the present disclosure has a smaller structural size, and the selective arrangement space on the housing 100 is wider, and does not affect other structures, and the manufacturing cost can also be saved. More particularly, the earpiece device can meet the listening requirement of the user only through the at least one pinhole-type sound outlet 110, so that the earpiece device has strong practical performance.

According to some embodiments, referring to fig. 1 to 3, the sound generating element 210 may be a moving iron sound generating unit, and the sound guiding channel 220 may be configured as a sound guiding tube, so that the sound generated by the moving iron sound generating unit is transmitted to the pinhole type sound outlet 110 through the sound guiding tube and then transmitted to the outside. Although the sound that moves indisputable sound generating unit sent can transmit through aperture pipeline form (satisfy pinhole formula sound production design promptly), its tone quality can not reach the tone quality requirement of earphone device, so can connect the leading note pipe at its sound outlet end, the leading note pipe can also adjust the tone quality of the sound that moves indisputable sound generating unit sent except that can transmit sound, moves the sound that indisputable sound generating unit sent promptly and transmits to the external world after leading note pipe optimization adjusts to can satisfy the tone quality demand of earphone device. Wherein, the sound guide tube can be configured in a circular shape, and the material can be preferably a resin material.

It should be noted that the sound guide tube may have a size adapted to the design according to the actual requirement. The voice frequency band is usually 450Hz-4.5KHz, the wavelength is 76mm-760mm, and the voice frequency band belongs to the high-middle-high frequency band. Through the length with the leading note pipe with high frequency sound wave and the reasonable setting of low frequency sound wave, can be so that high frequency speech signal in the inside transmission course of body with the pipe wall bump the refraction in order to offset the decay, and low frequency speech signal vibration is slower, the wavelength is longer, consequently the relative refraction less can not produce the decay to because have longer air column in the body, can correspondingly promote the low frequency effect. Further, since the smaller the diameter of the sound guide tube, the more the high-frequency components of the sound to be emitted become sharper, and the lower-frequency sound waves are relatively blocked and the sound cannot be emitted, the diameter of the sound guide tube should be appropriately selected. In the embodiment of the present disclosure, the size of the sound guiding tube may be selected by taking the characteristics of the pinhole type sound outlet 110 and the moving iron sound generating unit into consideration.

Further, referring to fig. 2, the low frequency module 201 may include a low frequency moving iron sounding unit 211 and a low frequency pipe 221, and the intermediate frequency module 202 may include a medium frequency moving iron sounding unit 212 and a medium frequency pipe 222, so that the voice signal concentrated in the low frequency band may be transmitted to the outside through the low frequency module 201, and the voice signal concentrated in the medium frequency band may be correspondingly transmitted to the outside through the intermediate frequency module 202. The length of the low-frequency sound guiding tube 221 is greater than that of the medium-frequency sound guiding tube 222, so that the low-frequency sound guiding tube and the medium-frequency sound guiding tube respectively exhibit corresponding low-medium frequency effects. For example, the length of the low frequency sound guiding tube 221 may be 140mm to 185mm, preferably 165 mm; the length of the mid-frequency sound guide tube 222 may be 40mm to 65mm, preferably 50 mm.

Further, referring to fig. 3, the moving iron sound emitting unit may include a sound outlet 213, and one end of the sound guide tube may be connected to the sound outlet 213, and the other end may be connected to the pinhole type sound outlet 110. Wherein, the sound guide tube can be fixedly connected with the sound outlet mouth 213 by bonding and the like.

In addition, as shown in fig. 3, the moving-iron sound emitting unit may be configured in a rectangular shape, and a shock pad 213 may be wrapped thereon. The damper pad 213 may not be provided at a position of the moving iron sound emitting unit where the sound outlet 213 is provided, so as to avoid interference with the sound outlet 213. The shock pad 230 can prevent the moving iron sounding unit from vibrating the casing 100 and other electronic components inside the casing 100 when the moving iron sounding unit works, thereby preventing the problems of sound leakage and noise caused by the vibration of the casing 100, and reducing the probability of damage to the electronic components due to frequent vibration. In the embodiment of the handset apparatus applied to electronic devices such as mobile phones, the shock pad 230 can also prevent the mobile phone shell from generating abnormal vibration feeling when contacting with hands, ears and face due to vibration during a call, thereby improving the user's feeling of use. Among them, the damper pad 230 may be preferably made of butyl rubber material, and may have a square structure matching with the structure of the moving iron sound emitting unit.

It should be noted that the present disclosure does not limit the structural form of the sound generating element 210, and for example, the sound generating element 210 may be a moving coil speaker, in addition to the moving iron sound generating unit described above. The moving iron sounding unit and the moving coil loudspeaker are electroacoustic elements, vibration sounding can be generated along with input electric signals, and the electric signals change vibration states and can also follow the vibration of different states to generate different sounds. The moving iron sounding unit and the moving coil loudspeaker can be preferably of a medium-low frequency and high-sensitivity type. In other embodiments, the sound generating element 210 may be configured in a piezoelectric type, an electromagnetic type, or the like, and the sound guide channel 220 may be configured to be adapted to the sound generating element 210.

In the embodiment provided by the present disclosure, referring to fig. 1, the sound generating element 210 and the sound guiding channel 220 may be arranged inside the casing 100 in a straight line, that is, the moving-iron sound generating unit and the sound guiding tube may be arranged inside the casing 100 in sequence, and both are located on the same straight line. The arrangement mode not only can save the inner space of the shell 100, but also can reduce the resistance of the sound in the outward transmission process as much as possible, reduce the sound transmission path and ensure better tone quality effect.

To avoid sound leakage when the sound is transmitted through the sound guiding channel 220 and to take into account the aesthetic aspects of the earpiece device, the end of the sound guiding channel 220 may abut against the inner end surface of the pinhole sound outlet 110. For example, the end of the sound guiding tube may be fixed against the inner end surface of the pinhole type sound outlet 110, so as to avoid a gap from being generated between the sound guiding tube and the casing 100.

Further, the inner diameter of the sound guiding tube may be the same as the diameter of the pinhole type sound outlet 110, for example, the inner diameter of the sound guiding tube may also be preferably 0.8mm, and the sound guiding tube may be radially aligned with the pinhole type sound outlet 110, so that sound can be smoothly transmitted to the outside through the transmission channel without an inflection point, sound attenuation is reduced, and the requirement of the earphone sound quality is met to the maximum extent.

In addition, referring to fig. 3, in order to prevent the end of the sound guide channel 220 connected to the pinhole-type sound outlet 110 from being affected by external dust and liquid (e.g., water, oil), the end of the sound guide channel 220 used to connect to the pinhole-type sound outlet 110 may be sequentially installed with a waterproof breathable film 300 and a dust-proof net 400, i.e., the dust-proof net 400 may be installed outside the waterproof breathable film 300 for effective waterproofing and dust-proof.

Fig. 4 to 7 show the audio frequency curves obtained by testing with different configurations of the handset device. Wherein, the earphone device that adopts in fig. 4 includes two moving iron sound production units, two leading note pipes that are connected with moving iron sound production unit respectively and the shock pad of parcel on moving iron sound production unit respectively (can be for the above-mentioned earphone device that this disclosure provided), the earphone device that adopts in fig. 5 includes a moving iron sound production unit and the leading note pipe of being connected with this moving iron sound production unit, the earphone device that adopts in fig. 6 includes a moving iron sound production unit and the shock pad of parcel on this moving iron sound production unit, the earphone device that adopts in fig. 7 only includes a moving iron sound production unit. In fig. 4 to 7, the reference value between the upper limit and the lower limit is an ideal audio curve, and can play sound with good quality; if the reference value exceeds the upper limit or falls below the lower limit, the non-ideal audio curve will emit sound with fewer flaws, and vice versa, the closer the curve in the non-ideal audio curve is to the region between the upper and lower limits. As is apparent from fig. 4 to 7, the audio curves obtained by the tests performed with the handset device according to the present disclosure are substantially all located between the upper limit and the lower limit, so that relatively good quality sound can be played, and the sound quality thereof can meet the requirements of the handset device.
