[0001] The present application belongs to the field of acoustic technology, and specifically relates to an electronic device. Background Art

[0002] With the rapid development of electronic devices, people's demand for mobile phone calls has gradually increased. Initially, in the era of feature phones, people only wanted to be able to hear and not be disconnected. In the subsequent smartphone era, people hope to hear clearly and comfortably. With the successive generations of mobile phones, people are more concerned about call leakage. In public places such as meetings, elevators, and subways, people generally do not want their conversations to be overheard by others and cause privacy leaks.

[0003] To reduce sound leakage during calls, existing solutions mainly focus on the following aspects, including reducing the loudness of the sound source; using pop-up devices to block sound leakage along the leakage path; adding reverse sound-emitting devices to reversely offset the sound leakage, etc.

[0004] Existing solutions have the following defects: the existing solution of reducing the loudness of the sound source, although it reduces sound leakage, also causes the volume of the call voice received by the user to be reduced, and the call is not loud enough and difficult to hear clearly; using a pop-up structure to cover the sound leakage path to block sound leakage requires adding additional mechanical structure, making the whole device bulky; and the solution of adding a reverse sound-emitting device can block less sound leakage due to the sound diffraction effect, and the anti-leakage effect is average. Summary of the Invention

[0005] The present application aims to provide an electronic device that at least solves one of the problems of inconvenience in using the sound leakage prevention mode of existing electronic devices.

[0006] In order to solve the above technical problems, this application is implemented as follows:

[0008] In an embodiment of the present application, a first sound hole corresponding to the front sound cavity and a second sound hole corresponding to the rear sound cavity are opened on the electronic device. When the mute key adjusts the electronic device to normal mode, the first sound hole is connected to the front sound cavity, and the front sound cavity can emit sound through the first sound hole and the sound outlet hole, thereby improving the sound quality effect; when the mute key adjusts the electronic device to mute mode, the second sound hole is connected to the rear sound cavity, and the front sound cavity emits sound through the sound outlet hole.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0028] The electronic device 100 according to an embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0029] like Figures 1 to 8 As shown, the electronic device 100 according to an embodiment of the present application has a normal mode and a silent mode, wherein the electronic device 100 includes a housing 10 , a speaker assembly 20 and a silent key 30 .

[0030] Specifically, a housing 10 is provided with a storage space. A first sound hole 11 and a second sound hole 12 are provided on the sidewall of the housing 10, communicating with the storage space. The housing 10 is provided with a sound outlet 13, with the first sound hole 11 being adjacent to the sound outlet 13. A speaker assembly 20 is provided in the storage space. The speaker assembly 20 cooperates with the housing 10 to define a front sound cavity 21 and a rear sound cavity 22. The first sound hole 11 corresponds to the position of the front sound cavity 21, the second sound hole 12 corresponds to the position of the rear sound cavity 22, and the sound outlet 13 communicates with the front sound cavity 21. A mute button 30 is movably provided on the housing 10 between a first position and a second position. When the mute button 30 is in the first position, the mute button 30 blocks the second sound hole 12, the first sound hole 11 communicates with the front sound cavity 21, and the electronic device 100 is in normal mode. When the mute button 30 is in the second position, the mute button 30 blocks the first sound hole 11, the second sound hole 12 communicates with the rear sound cavity 22, and the electronic device is in mute mode.

[0031] In other words, the electronic device 100 according to the embodiment of the present application is mainly composed of a shell 10 constituting the main structure of the device, a speaker assembly 20 provided in the shell 10 and capable of making sounds, and a mute button 30 capable of controlling the sound effect of the speaker assembly 20. The shell 10 forms different shapes and structures according to different forms of the electronic device 100. The shell 10 can be an integral structure or an assembled structure composed of multiple parts. For example, the shell 10 can be a closed structure composed of a cover 101, a frame 102, and a screen 103. In addition to accommodating the speaker assembly 20, the accommodation space in the shell 10 is also equipped with other functional structures, such as a main board 201, a main board bracket 202 for mounting the main board 201, a sub-board 203, a battery 204, a camera module 205, and other structures (such as Figure 2 As shown), these structures are understandable and easy to implement for those skilled in the art, and therefore will not be described in detail.

[0032] A first sound hole 11 and a second sound hole 12 are provided on one side of the housing 10. Furthermore, a sound outlet 13 is provided on the housing 10. The first sound hole 11, the second sound hole 12, and the sound outlet 13 are preferably positioned so that a user can clearly hear the sound emitted by the speaker assembly 20. The speaker assembly 20 is disposed within the housing 10. The position of the speaker assembly 20 matches the positions of the first sound hole 11, the second sound hole 12, and the sound outlet 13, so that the sound emitted by the speaker assembly 20 can be easily transmitted through the first sound hole 11, the second sound hole 12, and the sound outlet 13.

[0033] There is no special restriction on the assembly structure of the speaker assembly 20 in the shell 10, as long as the speaker assembly 20 can cooperate with the shell 10 to define the front sound cavity 21 and the rear sound cavity 22. The speaker assembly 20 may include a speaker 23, a front cavity seal 24 and a rear cavity seal 25. The speaker 23 is arranged in the shell 10 and can be separated from the two opposite side walls of the shell 10 to form the front sound cavity 21 and the rear sound cavity 22. The sound outlet 13 remains connected with the front sound cavity 21. The front cavity seal 24 can seal the front sound cavity 21 to separate it from the rest of the structure in the shell 10, and the rear cavity seal 25 can seal the rear sound cavity 22 to separate it from the rest of the structure in the shell 10.

[0034] The position of the front sound cavity 21 corresponds to the position of the first sound hole 11. When the front sound cavity 21 is connected to the first sound hole 11, the sound emitted by the speaker assembly 20 can be emitted from the first sound hole 11 and the sound outlet 13 through the front sound cavity 21, thereby adding a sound outlet channel for the front sound cavity, optimizing the air flow rate in the sound cavity, and improving the external sound effect; the position of the rear sound cavity 22 corresponds to the position of the second sound hole 12. When the rear sound cavity 22 is connected to the second sound hole 12, the sound emitted by the speaker assembly 20 can be emitted from the sound outlet 13 through the front sound cavity 21, and at the same time, emitted from the second sound hole 12 through the rear sound cavity 22.

[0035] The mute button 30 is movably disposed on the housing 10, and may be disposed on or within the housing 10. The mute button 30 is movable between a first position and a second position, thereby connecting the first sound hole 11 to the front sound cavity 21, or connecting the second sound hole 12 to the rear sound cavity 22. The mute button 30 can be switched between the first position and the second position by manual adjustment, or can be driven to move within the housing 10 by a motor or other drive member.

[0036] When the mute button 30 is in the first position, at least a portion of the mute button 30 avoids the position between the first sound hole 11 and the front sound cavity 21, so that the first sound hole 11 is connected to the front sound cavity 21. At the same time, the mute button 30 can be located between the second sound hole 12 and the rear sound cavity 22 to block the connection between the second sound hole 12 and the rear sound cavity 22. At this time, the electronic device 100 is in normal mode, the rear sound cavity 22 is closed, and the sound emitted by the speaker assembly 20 can be emitted from the first sound hole 11 and the sound outlet 13 through the front sound cavity 21. Since the first sound hole 11 is close to the sound outlet 13, when the first sound hole 11 is connected to the front sound cavity 21, the effective sound output area of ​​the speaker assembly 20 can be increased, effectively improving the problem of noisy airflow in high-volume scenes, and improving the external listening experience and sound field of the speaker assembly.

[0037] When the mute button 30 is in the second position, at least a portion of the mute button 30 avoids the position between the second sound hole 12 and the rear sound cavity 22, so that the second sound hole 12 is connected to the rear sound cavity 22. At the same time, the mute button 30 can be located between the first sound hole 11 and the front sound cavity 21 to block the connection between the first sound hole 11 and the front sound cavity 21. At this time, the electronic device 100 is in silent mode, the front sound cavity 21 is disconnected from the first sound hole 11 and is only connected to the sound outlet 13, and the rear sound cavity 22 is connected to the second sound hole 12. Part of the sound emitted by the speaker assembly 20 can be emitted from the sound outlet 13 through the front sound cavity 21, and the other part can be emitted from the second sound hole 12 through the rear sound cavity 22. Since the sound waves emitted from the second sound hole 12 through the rear sound cavity 22 are in opposite phases to the sound waves emitted from the sound outlet 13, the two sound waves will cancel each other out after interfering with each other, thereby achieving the effect of preventing sound leakage.

[0038] like Figure 4 As shown, the sound waves emitted from the sound outlet 13 are front cavity leakage sound waves, and their propagation direction is as follows: Figure 4 As shown by the arrow a in the middle, the sound wave emitted from the second sound hole 12 is the back cavity leakage sound wave, and its propagation direction is as follows: Figure 4As shown by the middle arrow b, the sound waves leaking from the front cavity will be reflected after encountering an obstacle (such as a human face), and the reflected sound waves will couple with the sound waves leaking from the rear cavity. Since the sound waves in the front acoustic cavity 21 and the rear acoustic cavity 22 have opposite phases, they will interfere with each other in the air and cancel each other out, thereby achieving the effect of preventing sound leakage.

[0039] Therefore, according to the electronic device 100 of an embodiment of the present invention, by opening a first sound hole 11 corresponding to the front sound cavity 21 and a second sound hole 12 corresponding to the rear sound cavity 22 on the electronic device, when the mute key 30 adjusts the electronic device 100 to be in normal mode, when the first sound hole 11 is connected with the front sound cavity 21, the front sound cavity 21 can make sound through the first sound hole 11 and the sound outlet hole 13, thereby improving the sound quality effect; when the mute key 30 adjusts the electronic device 100 to be in silent mode, when the second sound hole 12 is connected with the rear sound cavity 22, the front sound cavity 21 makes sound through the sound outlet hole 13, and the sound waves emitted by the rear sound cavity 22 can be phase-offset with the sound waves emitted by the front sound cavity 21, thereby effectively reducing call leakage and protecting user privacy. The electronic device 100 can quickly switch between the effects of preventing sound leakage and improving sound quality by adjusting the mute key 30, and has a simple structure and is easy to operate.

[0040] According to one embodiment of the present application, the mute key 30 is a movable key with at least a portion extending out of the housing 10 .

[0041] That is, in this embodiment, the mute key 30 is a manually adjustable key structure. A portion of the mute key 30 extends out of the housing 10, allowing the user to manually push the mute key 30 to switch between the first position and the second position. The mute key 30 has a simple structure, requires minimal modification to the existing electronic device 100, is low-cost, and is easy to operate and convenient to use.

[0042] Optionally, in some specific embodiments of the present application, the mute key 30 includes: a main body portion 31 and a pressing portion 32 .

[0043] Specifically, the main body 31 is a sheet-like structure, and the main body 31 is movably disposed between the side wall of the housing 10 and the speaker assembly 20 . The pressing portion 32 is connected to the main body 31 , and a portion of the pressing portion 32 extends out of the housing 10 .

[0044] like Figure 5 and Figure 6As shown, the mute button 30 in the present application can be composed of a main body 31 and a pressing portion 32. The main body 31 is arranged in the space formed by the space between the side wall of the housing 10 and the speaker assembly 20, and the shape of the main body 31 corresponds to the shape of the space. For example, it can be formed into a sheet-like structure so that the main body 31 can move in the space. The pressing portion 32 is arranged on the side of the main body 31 facing the outside of the housing 10, and a part of the pressing portion 32 extends from the housing 10 to facilitate the user to manually press the mute button 30, thereby facilitating the user to quickly adjust the sound effect of the speaker assembly 20 according to the needs of use.

[0045] The main body portion 31 and the pressing portion 32 can be manufactured in an integrated manner. This structure is not only convenient for molding but also can ensure the overall structural stability.

[0046] According to some embodiments of the present application, the electronic device 100 is a handheld mobile terminal.

[0047] In other words, the electronic device 100 according to the embodiment of the present application can be a mobile phone, and the mute button 30 is the mute button of the mobile phone. By adjusting the mute button of the mobile phone, the operating mode of the mobile phone can be adjusted while also adjusting the sound effect of the speaker assembly 20. The mobile phone is provided with a mute button, and when it is turned on, the global external speaker is muted, meeting the mute needs of scenes such as meetings and sleeping.

[0048] For example, when the mobile phone is in normal mode, the mute button 30 is in the first position. At this time, the first sound hole 11 is connected to the front sound cavity 21, and the front sound cavity 21 can make sound through the first sound hole 11 and the sound outlet 13, thereby improving the sound quality. Users can get a better external sound quality experience.

[0049] When the mobile phone is in silent mode, the mute button 30 is in the second position. At this time, the second sound hole 12 is connected to the rear sound cavity 22, and the front sound cavity 21 emits sound through the sound outlet 13. The sound waves emitted by the rear sound cavity 22 can offset the phase of the sound waves emitted by the front sound cavity 21, thereby effectively reducing call leakage and protecting user privacy.

[0050] Therefore, by reusing the original mute button on the mobile phone, the audio optimization function can be switched while switching the position of the mute button. The structure is simple, there is no need to increase the device cost of the mobile phone, and the feasibility is strong.

[0051] In some specific embodiments of the present application, the shell 10 includes a frame 102, the first sound hole 11, the second sound hole 12 and the mute button 30 are respectively arranged in the frame 102, the sound outlet hole 13 is arranged on the front surface of the frame 102, and a sound outlet channel is provided between the sound outlet hole 13 and the front sound cavity 21, and the first sound hole 11 is opposite to the sound outlet channel.

[0052] Specifically, if Figures 1 to 3 As shown, the electronic device 100 has an overall rectangular structure, such as that of a commonly used mobile phone. The mute button 30 is the mute button of the mobile phone and is movably disposed on the top of the mobile phone. Furthermore, the first sound hole 11 and the second sound hole 12 are also disposed on the top of the mobile phone and are spaced apart on either side of the mute button 30 in the thickness direction of the mobile phone. Taking into account the specific structure of the mobile phone, the first sound hole 11, the second sound hole 12, and the mute button 30 can be disposed in the frame 102 of the mobile phone. To improve the sound quality of the mobile phone, the first sound hole 11 and the second sound hole 12 can be positioned close to the user's ear when answering the phone. The sound outlet 13 can be disposed on the side of the mobile phone where the screen is located, with the first sound hole 11 close to the sound outlet 13 in the thickness direction of the mobile phone, and the second sound hole 12 away from the sound outlet 13 in the thickness direction of the mobile phone.

[0053] It should be noted that the positions of the first sound hole 11, the second sound hole 12 and the mute button 30 can also be set at other positions of the electronic device 100, as long as the electronic device 100 can achieve the effect of convenient switching of the audio optimization function when in use.

[0054] Thus, according to the electronic device 100 of the embodiment of the present application, the first sound hole 11 and the second sound hole 12 are set on the top of the phone. By adjusting the position of the mute button 30, the two small holes can be switched between closed and closed. When the first sound hole 11 is open, it helps improve the upward air flow rate of the phone, enhances the sound quality and reduces the risk of noise. When the second sound hole 12 is open, the phase offset between the front and rear cavities can effectively reduce call leakage and protect user privacy.

[0055] According to some embodiments of the present application, the main body 31 is provided with a first through hole 311 and a second through hole 312 which pass through the main body 31 along the thickness direction thereof. When the mute key 30 is in the first position, the first through hole 311 connects the first sound hole 11 and the front sound cavity 21. When the mute key 30 is in the second position, the second through hole 312 connects the second sound hole 12 and the rear sound cavity 22.

[0056] in, Figure 5 and Figure 6 is a structural diagram of the mute key 30 when it is in the first position, Figure 7 and Figure 8 This is a structural diagram when the mute key is in the second position.

[0057] Specifically, the main body 31 is a sheet-like structure, provided with a first through hole 311 and a second through hole 312. The apertures of the first through hole 311 and the second through hole 312 may correspond to the apertures of the first sound hole 11 and the second sound hole 12, respectively. Providing through holes in the main body 31 allows for communication between the front acoustic cavity 21 and the first sound hole 11, and between the rear acoustic cavity 22 and the second sound hole 12. This reduces diffusion and sound leakage that occurs when sound waves flow from the front acoustic cavity 21 to the first sound hole 11 and from the rear acoustic cavity 22 to the second sound hole 12, thereby ensuring efficient sound wave propagation and sound quality.

[0058] like Figure 5 and Figure 6 As shown, when the mute button 30 is in the first position, the first through hole 311 corresponds to the position of the first sound hole 11 and the front sound cavity 21. The front sound cavity 21 can be connected to the first sound hole 11 through the first through hole 311. At this time, the second sound hole 12 is disconnected from the rear sound cavity 22, and the sound waves emitted by the speaker assembly 20 are transmitted from the front sound cavity 21 through the first sound hole 11 and the sound outlet 13. When the electronic device 100 is a mobile phone and the mute button 30 is the mute button of the mobile phone, at this time, the mobile phone is in normal mode, the mute button is turned away from the screen, the first sound hole 11 is in the open state, and the front cavity seal 24 is between the frame 102 and the screen 103, forming an upward front cavity sound outlet channel. In this state, the first sound hole 11 is open, which increases the effective upward sound outlet area, which can effectively improve the airflow noise problem in high-volume scenarios and enhance the external listening experience and sound field.

[0059] like Figure 7 and Figure 8 As shown, when the mute button 30 is in the second position, the second through hole 312 corresponds to the positions of the second sound hole 12 and the rear sound cavity 22, and the rear sound cavity 22 can be connected with the second sound hole 12 through the second through hole 312. At this time, the first sound hole 11 is disconnected from the front sound cavity 21, and the sound waves emitted by the speaker assembly 20 are divided into two parts. One part of the sound waves is transmitted from the front sound cavity 21 through the sound outlet 13, and the other part of the sound waves is transmitted from the rear sound cavity 22 through the second sound hole 12. When the electronic device 100 is a mobile phone and the mute button 30 is the mute button of the mobile phone, at this time, the mobile phone is in silent mode, the mute button is pressed close to the screen, the second sound hole 12 is in the open state, the rear cavity seal 25 and the mainboard bracket 202 enclose the rear sound cavity 22 into a sealed space, that is, the rear cavity sound outlet channel. When the mute button is pressed and the second sound hole 12 is opened, the rear cavity sound outlet channel is connected to the outside world. The sound waves of the rear sound cavity 22 are opposite in phase to the sound waves of the sound outlet 13, and cancel each other out after interference, thereby achieving the effect of preventing sound leakage.

[0060] Therefore, by setting the first through hole 311 and the second through hole 312 on the mute button 30, the sound effect of the speaker assembly 20 can be conveniently adjusted by adjusting the mute button 30, which is more convenient to use and has lower cost.

[0061] In some specific embodiments of the present application, the distance between the first through hole 311 and the second through hole 312 is greater than the distance between the first sound hole 11 and the second sound hole 12 .

[0062] Optionally, the pressing portion 32 is disposed between the first through hole 311 and the second through hole 312 .

[0063] In other words, the apertures of the first through hole 311 and the second through hole 312 can be equal to the apertures of the first sound hole 11 and the second sound hole 12, respectively, and the distance between the first through hole 311 and the second through hole 312 on the body portion 31 is greater than the distance between the first sound hole 11 and the second sound hole 12 on the housing 10, and correspondingly greater than the distance between the front sound cavity 21 and the rear sound cavity 22. This structural design ensures that when the first through hole 311 is connected to the front sound cavity 21, the second through hole 312 is offset from the second sound hole 12 and the rear sound cavity 22 in the axial direction of the second sound hole 12, and the second sound hole 12 and the rear sound cavity 22 are blocked by the body portion 31 and cannot be connected. Similarly, when the second through hole 312 is connected to the rear sound cavity 22, the first through hole 311 is offset from the first sound hole 11 and the front sound cavity 21 in the axial direction of the first sound hole 11, and the first sound hole 11 and the front sound cavity 21 are blocked by the body portion 31 and cannot be connected.

[0064] The pressing portion 32 is disposed between the first through hole 311 and the second through hole 312 , and preferably can be disposed in the middle of the main body 31 , so that the pressing portion 32 can accurately control the sound effect of the speaker assembly 20 within a smaller range of movement.

[0065] Therefore, according to the electronic device 100 of the embodiment of the present application, the structural design of the mute key 30 is more reasonable, the adjustment of the speaker assembly 20 is more convenient, and the adjustment effect is better.

[0066] According to other embodiments of the present application, the mute key 30 is a sheet-like structure, and the mute key 30 can be movably arranged between the side wall of the shell 10 and the speaker assembly 20. The electronic device 100 also includes: a driving member (not shown), the driving member is arranged in the shell 10, and the driving member is connected to the mute key 30 to drive the mute key 30.

[0067] That is to say, according to the embodiment of the present application, the mute key 30 of the electronic device 100 can be a manually operated structure or a structure driven by a driver. When the mute key 30 is driven by a driver, the mute key 30 does not need to be extended out of the shell 10 to be manually controlled by the user, but can be controlled by an operating program inside the electronic device 100.

[0068] Optionally, in some specific embodiments of the present application, the electronic device 100 is a handheld mobile terminal, and the driving component drives the mute key 30 to be in the first position when the electronic device 100 is in normal mode, and drives the mute key 30 to be in the second position when the electronic device 100 is in silent mode.

[0069] In other words, the electronic device 100 according to the embodiment of the present application can be a mobile phone, which has two modes: normal mode and silent mode. The mode switching of the mobile phone can control the driver to drive the silent key 30. When the mobile phone is in normal mode, the driver can drive the silent key 30 to the first position, at which time the user can enjoy a better external speaker sound quality experience. When the mobile phone is in silent mode, the driver can drive the silent key 30 to the second position, at which time, the call has a sound leakage prevention effect, effectively protecting privacy.

[0070] It should be noted that the mute button 30 can also be driven by the user using different functions of the mobile phone. For example, when the user is making a call, the mobile phone can automatically control the driver to drive the mute button 30 to the second position to prevent sound leakage; and when the user is using other sound functions, the mobile phone can automatically control the driver to drive the mute button 30 to the first position, so that the user can get a better external sound quality experience. The driver can be a motor of the electronic device, which can be a separate motor or a motor that can be reused by the electronic device to drive a camera or other structure.

[0071] Therefore, by setting a driving member in the electronic device 100, the driving member can automatically control the position of the mute button 30 according to the usage mode or setting of the mobile phone, thereby eliminating the need to manually adjust the sound effect of the speaker assembly 20, making it more convenient to use.
