Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Referring to fig. 1 to 7, an embodiment of the invention discloses an electronic device, which includes a device body 100, a first sound generating device 200 and a second sound generating device 300.

The apparatus body 100 is a body portion of the electronic apparatus. In a general case, the apparatus main body 100 includes main constituent elements of the electronic apparatus, and for example, the apparatus main body 100 may include an apparatus housing and functional elements such as a display screen 100c, a battery, a main board, and the like mounted on the apparatus housing. In the embodiment of the present invention, the device main body 100 is formed with a first sound outlet 110, a second sound outlet 120, a first mounting cavity 130, a second mounting cavity 140, a first sound guiding channel 150, a second sound guiding channel 160, and a third sound outlet 170.

In the embodiment of the present invention, the orientations of the second sound emitting hole 120 and the third sound emitting hole 170 are different from the orientation of the first sound emitting hole 110, and the orientations of the second sound emitting hole 120 and the third sound emitting hole 170 may be the same or different. Specifically, the first sound emitting hole 110 may be located at a first side of the device body 100, and the second and third

sound emitting holes

120 and 170 may be located at a second side of the device body 100.

The first sound generating device 200 and the second sound generating device 300 are devices capable of generating sound for electronic equipment, for example, the first sound generating device 200 and the second sound generating device 300 may be receivers. During operation of the first sound emitting device 200 and the second sound emitting device 300, sound generated by the first sound emitting device 200 can be transmitted to the environment in which the electronic equipment is located through the first sound outlet hole 110 and the second sound outlet hole 120. The sound generated by the second sound emitting device 300 can be transmitted to the environment in which the electronic equipment is located through the first sound emitting hole 110 and the third sound emitting hole 170.

The first sound emitting device 200 is disposed in the first mounting cavity 130, thereby achieving the assembly with the apparatus main body 100. First sound-emitting device 200 divides first mounting cavity 130 into first subchamber 131 and second subchamber 132. First subchamber 131 and second subchamber 132 are hermetically isolated. The first sub-chamber 131 is communicated with the first sound emitting hole 110, and the second sub-chamber 132 is communicated with the second sound emitting hole 120 through the first sound guiding passage 150.

In the operation process of the first sound emitting device 200, the sound generated by the first sound emitting device 200 will sequentially pass through the first sub-cavity 131 and the first sound outlet hole 110 and then be transmitted to the environment where the electronic device is located, and the sound generated by the first sound emitting device 200 will sequentially pass through the second sub-cavity 132 and the second sound outlet hole 120 and then be transmitted to the environment where the electronic device is located.

The second sounder device 300 is disposed in the second mounting cavity 140 so as to be assembled with the apparatus body 100. The second sounder device 300 divides the second mounting cavity 140 into a third sub-cavity and a fourth sub-cavity. The third sub-chamber and the fourth sub-chamber are hermetically isolated. The third sub-chamber communicates with the first sound emitting hole 110, and the fourth sub-chamber communicates with the third sound emitting hole 170 through the second sound guiding passage 160.

Similarly, in the process of operating the second sound generating device 300, the sound generated by the second sound generating device 300 will sequentially pass through the third sub-cavity and the first sound outlet hole 110 and then be transmitted to the environment where the electronic device is located, and the sound generated by the second sound generating device 300 will sequentially pass through the fourth sub-cavity and the third sound outlet hole 170 and then be transmitted to the environment where the electronic device is located.

The first sound guiding channel 150 and the second sound guiding channel 160 are both channels capable of conducting sound. The first sound guiding channel 150 can adjust the phase of the second sound wave transmitted from the second sound output hole 120, and the second sound guiding channel 160 can adjust the phase of the third sound wave transmitted from the third sound output hole 170, so that the second sound wave transmitted from the second sound output hole 120 and the third sound wave transmitted from the third sound output hole 170 both satisfy the requirements described later.

The sound wave emitted by the first sound emitting device 200 through the first sound emitting hole 110 is a first sound wave, the sound wave emitted by the second sound emitting device 300 through the first sound emitting hole 110 is a fourth sound wave, the sound wave emitted by the first sound emitting device 200 through the second sound emitting hole 120 is a second sound wave, and the sound wave emitted by the second sound emitting device 300 through the third sound emitting hole 170 is a third sound wave. In the embodiment of the invention, the phases of the second sound wave and the first sound wave are different, and the phases of the third sound wave and the fourth sound wave are different, so that certain cancellation can be generated after the second sound wave meets the first sound wave and after the third sound wave meets the fourth sound wave, and the attenuation of sound in the transmission process is promoted.

The electronic device disclosed in the embodiment of the present invention improves the structure of the existing electronic device, by forming the first sound emitting hole 110 on the first side of the device main body 100 and forming the second sound emitting hole 120 and the third sound emitting hole 170 on the second side of the device main body 100, and by dividing the first mounting cavity 130 into the first sub-cavity 131 and the second sub-cavity 132 by the first sound emitting device 200, and by dividing the second mounting cavity 140 into the third sub-cavity and the fourth sub-cavity by the second sound emitting device 300, the first sound guiding channel 150 can change the phase of the second sound emitted from the second sound emitting hole 120, so that the phases of the second sound and the first sound are different, the phase of the third sound emitted from the third sound emitting hole 170 can be changed by the second sound guiding channel 160, and the phases of the third sound and the fourth sound are different, and a certain sound wave cancellation effect can be achieved when the first sound and the second sound meet and the third sound and the fourth sound, thereby effectively reducing the amount of sound leakage. The reduction of the volume of leaking out of sound for the user can make oneself implement clearer conversation through adjusting great volume at the in-process that uses electronic equipment to converse, simultaneously because take place between second sound wave and the first sound wave and between third sound wave and the fourth sound wave to offset, thereby can make the in-process decay at sound transmission great, and then can alleviate the phenomenon that the user hears the sound that electronic equipment sent around the in-process of conversation, reach the purpose of leak protection sound.

In a preferred scheme, the phase of the second sound wave is opposite to that of the first sound wave, and the phase of the third sound wave is opposite to that of the fourth sound wave, so that the second sound wave and the first sound wave meet each other and the third sound wave and the fourth sound wave meet each other to generate opposite phase cancellation, further attenuation of sound in a remote transmission process can be further increased, and further reduction of sound leakage amount of the electronic equipment is facilitated. Specifically, the second sound wave and the third sound wave may be the same in phase or different in phase. Similarly, the phases of the first sound wave and the fourth sound wave may be the same or different.

In a specific simulation test process, the simulation result can also verify that the sound is greatly attenuated in the sound emitting direction of the second sound emitting hole 120 and the third sound emitting hole 170.

As described above, the first sound emitting hole 110 is provided at the first side of the device body 100, and the second and third

sound emitting holes

120 and 170 are provided at the second side of the device body 100. In an alternative scheme, the first side and the second side may be two opposite sides of the device body 100, or two adjacent sides of the device body 100, that is, the first side and the second side are disposed adjacent to each other. In the case where the first side and the second side are opposite sides of the device body 100, the first sound emitting hole 110 and the second sound emitting hole 120 can realize simultaneous sound emission from opposite sides of the electronic device. In this case, it may be: the first side is the side of the electronic device on which the display screen 100c is mounted, and the second side is the other side of the electronic device on which the rear cover 100b is mounted. Of course, it may also be: the first side is a side of the electronic device on which the display screen 100c is mounted, and the second side is a side on which the electronic device is located, and may be, for example, an outer side of a middle frame of the electronic device.

In the embodiment of the present invention, the first sound guiding channel 150 and the second sound guiding channel 160 perform the functions of sound conduction and adjusting the phases of the second sound wave and the third sound wave, respectively. In a specific design process, the phase of the second sound wave and the phase of the third sound wave can be adjusted by adjusting parameters such as the length and the cross-sectional area of the first sound guiding channel 150 and the second sound guiding channel 160.

The first and second

sound generating devices

200 and 300 may be distributed in a variety of ways. Optionally, a connection line between the center of the first sound generating device 200 and the center of the second sound generating device 300 may be parallel to the top edge of the electronic device, so that the first sound generating device 200 and the second sound generating device 300 can be arranged in a more regular manner.

In a more preferred aspect, the first sound emitting device 200 and the second sound emitting device 300 may be symmetrically disposed on both sides of the first axis of symmetry, and the second sound emitting hole 120 and the third sound emitting hole 170 may be symmetrically disposed on both sides of the first axis of symmetry. The arrangement mode enables the first sound emitting device 200 and the second sound emitting device 300, and the second sound emitting hole 120 and the third sound emitting hole 170 to be symmetrically arranged along the first symmetry axis, so that the layout is more reasonable, the appearance performance of the electronic device is improved, and meanwhile, the balance of sound emission is improved.

Similarly, the first sound guiding channel 150 and the second sound guiding channel 160 may be disposed in a plurality of ways, in a specific embodiment, the first sound guiding channel 150 and the second sound guiding channel 160 may be symmetrically disposed on two sides of the first symmetric axis, and this manner of disposition enables better synchronicity between the sound transmitted to the second sound outlet hole 120 through the first sound guiding channel 150 and the sound transmitted to the third sound outlet hole 170 through the second sound guiding channel 160, thereby facilitating improvement of the sound performance of the electronic device.

To better adjust the phase of the second and third sound waves, the first sound guiding channel 150 and the second sound guiding channel 160 may each be a bar channel. A first end of the first sound guiding channel 150 is communicated with the second sub-cavity 132, and a second end of the first sound guiding channel 150 is communicated with the second sound outlet 120. The third end of the second sound guiding channel 160 is communicated with the fourth sub-cavity, and the fourth end of the second sound guiding channel 160 is communicated with the third sound outlet 170. Specifically, the first end of the first sound guiding channel 150 and the second end of the first sound guiding channel 150 may be sequentially disposed in the length direction of the electronic device, and the third end of the second sound guiding channel 160 and the fourth end of the second sound guiding channel 160 may also be sequentially disposed in the length direction of the electronic device.

In the embodiment of the present invention, the shape and distribution of the first sound guiding channel 150 and the second sound guiding channel 160 are various. In one embodiment, as shown in FIG. 1, the first sound guiding channel 150 and the second sound guiding channel 160 may be parallel. In another embodiment, the first sound guiding channel 150 and the second sound guiding channel 160 may be perpendicular, as shown in fig. 4. Herein, the second sound guiding channel 160 may also extend along a length direction of the electronic device or a width direction of the electronic device. Of course, the first sound guiding channel 150 and the second sound guiding channel 160 may also extend in other directions.

Here, the length direction of the electronic device refers to a direction having a larger size in the plane of the display screen 100c of the electronic device, and the width direction of the electronic device is perpendicular to the length direction of the electronic device. In a general case, a projection of the electronic device perpendicular to the display screen 100c is a rectangular or oblong structure similar to a rectangle, a longitudinal direction of the electronic device may be regarded as a direction in which a long side of the projection extends, and a width direction of the electronic device may be regarded as a direction in which a wide side of the projection extends. The top edge of the electronic device described herein may be considered to be the edge of the electronic device corresponding to one of the broadsides of the projection.

In another embodiment, referring to fig. 3, the axes of the first sound guiding channel 150 and the second sound guiding channel 160 may be the same, and the first sound guiding channel 150 and the second sound guiding channel 160 may extend toward each other.

In the embodiment of the present invention, the first sound emitting hole 110, the second sound emitting hole 120, the first mounting cavity 130, the second mounting cavity 140, the first sound guiding channel 150, the second sound guiding channel 160, and the third sound emitting hole 170 may be formed in various manners. For example, the first sound emitting hole 110, the second sound emitting hole 120, the first mounting cavity 130, the second mounting cavity 140, the first sound guiding passage 150, the second sound guiding passage 160, and the third sound emitting hole 170 may be formed on the device case of the device body 100. Of course, at least some of the first sound outlet 110, the second sound outlet 120, the first mounting cavity 130, the second mounting cavity 140, the first sound guiding channel 150, the second sound guiding channel 160 and the third sound outlet 170 may be formed by the device housing together with other functional components of the electronic device (e.g. the display screen 100 c). The embodiment of the present invention does not limit the specific formation manner of the first sound emitting hole 110, the second sound emitting hole 120, the first mounting cavity 130, the second mounting cavity 140, the first sound guiding channel 150, the second sound guiding channel 160 and the third sound emitting hole 170.

In a general case, the device body 100 may include a device case, which may include a middle frame 100a, a rear cover 100b, and a front cover, and a display screen 100 c. The middle frame 100a, the rear cover 100b and the front cover are usually fixedly connected in a detachable manner, for example, the middle frame 100a and the rear cover 100b and the front cover and the middle frame 100a can be snap-fitted together.

In the two embodiments listed above, the display screen 100c may be disposed on the front cover or disposed on the rear cover 100b, and the front cover and the rear cover 100b are respectively connected to two opposite sides of the middle frame 100 a. The first sound guide channel 150 and the second sound guide channel 160 are surrounded by the rear cover 100b and the middle frame 100a, and the first sound guide channel 150 and the second sound guide channel 160 can be formed after the rear cover 100b and the middle frame 100a are assembled.

Alternatively, in the case that the display screen 100c is disposed on the front cover, one of the display screen 100c and the front cover is opened with the first sound outlet 110. In order to avoid the influence on the display 100c, in a preferred embodiment, a portion of the top end of the display 100c facing the middle frame 100a is surrounded by the first sound outlet 110. The method can also be as follows: in the case where the display screen 100c is provided in the rear cover 100b, one of the display screen 100c and the rear cover is opened with a second sound emitting hole 120 and a third sound emitting hole 170. The embodiment of the present invention does not limit the specific forming manner of the first sound emitting hole 110, the second sound emitting hole 120 and the third sound emitting hole 170.

Of course, the first installation cavity 130 and the second installation cavity 140 may be formed on the device housing separately, or may be enclosed by the device housing and the display screen 100 c. Referring again to fig. 2, the display screen 100c may enclose the first and second mounting

cavities

130 and 140 with the middle frame 100a and the rear cover 100b in a manner that facilitates the assembly of the first and second

sound generating devices

200 and 300.

As described above, the first sound producing device 200 is mounted to the first mounting cavity 130 and the second sound producing device 300 is mounted to the second mounting cavity 140. In order to facilitate the installation, in a preferable embodiment, in a case where the display screen 100c is disposed on the front cover, the middle frame 100a may include a first stopper 100a1, the rear cover 100b may include a first support 100b1, and the first sound generating device 200 may be disposed between the first stopper 100a1 and the first support 100b 1. Similarly, in the case that the display screen 100c is disposed on the front cover, the middle frame 100a may include a second position-limiting portion, the rear cover 100b may include a second supporting portion, and the second sound-generating device 300 may be disposed between the second position-limiting portion and the second supporting portion.

In an alternative, the first supporting portion 100b1 and the second supporting portion may be supporting protrusions, or may be other structures capable of supporting, such as supporting frames. The embodiment of the present invention does not limit the specific structures of the first support 100b1 and the second support.

The electronic device disclosed in the embodiment of the present invention may further include a camera module disposed on the second side of the device main body 100, that is, the camera module and the second sound outlet 120 and the third sound outlet 170 are located on the same side. The camera shooting module can realize the camera shooting function of the electronic equipment.

In a preferable scheme, both the first sound emitting hole 110 and the second sound emitting hole 120 may be provided with a dust-proof decorative net 400, the dust-proof decorative net 400 can play a dust-proof role, and meanwhile, the dust-proof decorative net 400 can prevent the first sound emitting hole 110 and the second sound emitting hole 120 from being directly exposed in a larger aperture, and further can play a certain decorative role. Specifically, the sound output size of the second sound output hole 120 can be adjusted by adjusting the parameters such as the mesh number, the thickness and the material of the dustproof decorative net 400, so as to achieve a better cancellation effect.

In the embodiment of the present invention, there may be one or at least two second sound emitting holes 120. In the case where there are at least two second sound emitting holes 120, the second sound emitting holes 120 may be spaced apart from each other. In a preferable embodiment, the second sound holes 120 may be disposed at equal intervals, that is, the distances between any two adjacent second sound holes 120 are equal, so that the second sound holes 120 at different positions can continuously cover different sound wave frequency bands, and further, the attenuation of sounds at different frequency bands can be promoted, and the suppression effect on sound leakage is enhanced.

Similarly, the number of the third sound emitting holes 170 may be one, or may be at least two. In the case where there are at least two third sound emitting holes 170, the third sound emitting holes 170 may be spaced apart from each other. In a preferable embodiment, the third sound holes 170 may be disposed at equal intervals, that is, the distances between any two adjacent third sound holes 170 are equal, so that the third sound holes 170 at different positions can continuously cover different sound wave frequency bands, and further, the attenuation of sounds at different frequency bands can be promoted, and the suppression effect on sound leakage is enhanced.

When the number of the second sound emitting holes 120 is at least two, the radiation width of the second sound wave can be widened, so that a better cancellation effect with the first sound wave can be realized. Similarly, when there are at least two third sound holes 170, the radiation width of the third sound wave can be widened, so that a better cancellation effect with the first sound wave can be achieved.

In the case that the number of the second sound emitting holes 120 is at least two, optionally, the first sound guiding channel 150 may be a strip-shaped channel, a first end of the first sound guiding channel 150 is communicated with the second sub-cavity 132, and at least one second sound emitting hole 120 is communicated with a second end of the first sound guiding channel 150. Other second sound outlet holes 120 may be disposed between the first end of the first sound guiding channel 150 and the second end of the first sound guiding channel 150. The layout mode is more favorable for improving the sound performance. Specifically, the second sound outlet holes 120 may be sequentially arranged along the extending direction of the first sound guide channel 150, as shown in fig. 7.

Similarly, in the case that the number of the third sound emitting holes 170 is at least two, optionally, the second sound guiding channel 160 may be a strip channel, specifically, the third end of the second sound guiding channel 160 is communicated with the fourth sub-cavity, and at least one third sound emitting hole 170 is communicated with the fourth end of the second sound guiding channel 160. Additional third sound outlet ports 170 may be disposed between the third end of the second sound guiding channel 160 and the fourth end of the second sound guiding channel 160. The layout mode is more favorable for balanced sounding, so that the sound performance can be improved. Specifically, the third sound outlet holes 170 may be sequentially arranged along the extending direction of the second sound guide channel 160, as shown in fig. 7.

In a more preferable embodiment, the first sound outlet hole 110 may be a strip-shaped hole, and as shown in fig. 1, 3, 4, 5, 6 and 7, an extending direction of the strip-shaped hole may be the same as a width direction of the electronic device. In this case, the first sound outlet hole 110 has a wider sound emitting range, which is beneficial to improving the sound performance of the electronic device.

Referring to fig. 5 and fig. 6, in an alternative scheme, the first sound guiding channel 150 may include a first main sound guiding channel 151 and a first sub sound guiding channel 152, a fifth end of the first main sound guiding channel 151 is connected to the second sub cavity 132, a sixth end of the first main sound guiding channel 151 may extend in a direction away from the second sub cavity 132, a seventh end of the first sub sound guiding channel 152 is connected between the fifth end of the first main sound guiding channel 151 and the sixth end of the first main sound guiding channel 151 and is communicated with the first main sound guiding channel 151, and an eighth end of the first sub sound guiding channel 152 may extend in a direction away from the first main sound guiding channel 151.

At least one of the first main sound guiding channel 151 and the first sub sound guiding channel 152 is in communication with the at least one second sound outlet hole 120. For example, as shown in fig. 5, the first main sound guiding channel 151 communicates with a second sound emitting opening 120, and the first sub sound guiding channel 152 communicates with a second sound emitting opening 120. As shown in fig. 6, the first main sound emitting passage 151 communicates with the two second sound emitting holes 120. In the above structure, since the first sound guiding channel 150 includes the first main sound guiding channel 151 and the first sub sound guiding channel 152, the structure formed by the first main sound guiding channel 151 and the first sub sound guiding channel 152 is more flexible, and the first sound guiding channel 150 can have a better function of adjusting the phase of the second sound wave.

Of course, the first main sound guiding channel 151 and the first sub sound guiding channel 152 are both communicated with at least one second sound outlet hole 120, so that the radiation width of the second sound wave can be further widened.

Referring to fig. 5 and fig. 6 again, in an alternative scheme, the second sound guiding channel 160 may include a second main sound guiding channel 161 and a second sub sound guiding channel 162, a ninth end of the second main sound guiding channel 161 is connected to the fourth sub-cavity, a tenth end of the second main sound guiding channel 161 extends in a direction away from the fourth sub-cavity, an eleventh end of the second sub sound guiding channel 162 is connected between the ninth end of the second main sound guiding channel 161 and the tenth end of the second main sound guiding channel 161 and is communicated with the second main sound guiding channel 161, and a twelfth end of the second sub sound guiding channel 162 extends in a direction away from the second main sound guiding channel 161.

At least one of the second main sound guiding passage 161 and the second sub sound guiding passage 162 communicates with at least one third sound outlet hole 170. For example, as shown in fig. 5, the second main sound guide channel 161 is communicated with a third sound emitting hole 170, and the second sub sound guide channel 162 is communicated with a third sound emitting hole 170. As shown in fig. 6, the second main sound channel 161 is communicated with two third sound outlet holes 170. In the above structure, since the second sound guide channel 160 includes the second main sound guide channel 161 and the second sub sound guide channel 162, the structure formed by the second main sound guide channel 161 and the second sub sound guide channel 162 is more flexible, and the second sound guide channel 160 can have a better function of adjusting the phase of the third sound wave.

Of course, the second main sound guide channel 161 and the second sub sound guide channel 162 are both communicated with at least one third sound outlet hole 170, which can further widen the radiation width of the third sound wave.

As described above, in the embodiment of the present invention, the first sound guiding channel 150 can adjust the phase of the second sound wave so that the second sound wave is different from the phase of the first sound wave, and the second sound guiding channel 160 can adjust the phase of the third sound wave so that the third sound wave is different from the phase of the fourth sound wave. Of course, the device main body 100 may further have a third sound guiding channel and a fourth sound guiding channel, the first sub-cavity 131 may be communicated with the first sound outlet 110 through the third sound guiding channel, and the third sound guiding channel may adjust the phase of the first sound wave. In this case, the first sound guiding channel 150 and the third sound guiding channel can make the second sound wave and the first sound wave have different phases, so that the sound wave cancellation is generated. Specifically, the first sound guiding channel 150 and the third sound guiding channel have different structures.

The third sub-chamber is communicated with the first sound outlet hole 110 through a fourth sound guide channel, and the fourth sound guide channel can adjust the phase of the fourth sound wave. In this case, the second sound guiding channel 160 and the fourth sound guiding channel can both make the third sound wave different from the fourth sound wave, thereby generating sound wave cancellation. Specifically, the second sound guiding channel 160 and the fourth sound guiding channel have different structures.

The electronic device disclosed by the embodiment of the invention can be a mobile phone, a tablet computer, an electronic book reader, a game machine, a vehicle-mounted navigator, an intelligent watch and other devices, and the embodiment of the invention does not limit the specific type of the electronic device.

In the above embodiments of the present invention, the difference between the embodiments is mainly described, and different optimization features between the embodiments can be combined to form a better embodiment as long as they are not contradictory, and further description is omitted here in view of brevity of the text.
