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 3, an electronic device according to an embodiment of the present disclosure includes a device housing 100, a sound generating device 200, and a sound collecting device 300.

The device case 100 is a base member of the electronic device, and can provide a mounting base for other members of the electronic device. Based on this, the sound producing device 200 and the sound collecting device 300 are mounted to the apparatus case 100. In the present embodiment, the sound producing device 200 and the sound collecting device 300 are provided in the apparatus case 100. Specifically, the device housing 100 may have a device inner cavity, and the sound generating device 200 and the sound generating device 300 may be disposed in the device housing 100 by fastening, adhering, connecting (e.g., screwing) or the like, so as to implement installation.

The sound generating device 200 is a device capable of generating sound in the electronic device, and the sound generating device 200 may be a speaker, a receiver, or other types of devices capable of generating sound, and the embodiment of the present application does not limit the specific type of the sound generating device 200. Specifically, the device housing 100 is provided with a sound emitting channel 210, the sound emitting device 200 is communicated with the sound emitting channel 210, and the sound emitting channel 210 is communicated with the external environment of the device housing 100. The sound emitted from the sound-emitting device 200 is transmitted to the external environment of the apparatus housing 100 through the sound-emitting channel 210, and finally the sound emission of the sound-emitting device 200 is realized.

The sound collecting device 300 is a device capable of collecting sound in the electronic device, and the sound collecting device 300 may be a microphone, and of course, may also be other types of devices capable of collecting sound, and the embodiment of the present application does not limit the specific type of the sound collecting device 300. In the embodiment of the present application, the sound collecting device 300 includes a diaphragm 310, and in the process of collecting sound by the sound collecting device 300, sound propagating in air may impact the diaphragm 310, so that the diaphragm 310 vibrates. The sound collecting device 300 converts the vibration of the diaphragm 310 into a sound signal, and finally collects the sound. Of course, the sound collecting principle of the sound collecting device 300 is a well-known technology, and is not described herein again in view of brevity of the text.

The sound collecting device 300 according to the embodiment of the present application is provided with a first cavity 301 and a second cavity 302, and the first cavity 301 is isolated from the second cavity 302, that is, the first cavity 301 and the second cavity 302 are not intercommunicated. The diaphragm 310 serves as one member of the sound collecting device 300 for forming the first chamber 301 and the second chamber 302 in cooperation with other members of the sound collecting device 300. Specifically, the diaphragm 310 has a first surface 311 and a second surface 312, where the first surface 311 and the second surface 312 are two surfaces of the diaphragm 310 that are distributed on the back in the vibration direction.

The first surface 311 of the diaphragm 310 faces the first cavity 301, in other words, the first surface 311 of the diaphragm 310 serves as a part of the inner wall of the first cavity 301, and the first surface 311 of the diaphragm 310 is used to cooperate with other components of the sound collecting device 300 to enclose the first cavity 301. The second surface 312 of the diaphragm 310 faces the second chamber 302, in other words, the second surface 312 of the diaphragm 310 serves as a part of the inner wall of the second chamber 302, and the second surface 312 of the diaphragm 310 is used to cooperate with other components of the sound collecting device 300 to enclose the second chamber 302.

The sound collecting device 300 according to the embodiment of the present application further has a first connection hole 303 and a second connection hole 304, the first cavity 301 is communicated with the external environment of the device housing 100 through the first connection hole 303, that is, the first cavity 301 is communicated with the first connection hole 303, the first connection hole 303 is communicated with the external environment of the device housing 100, and this communication relationship enables the first cavity 301 to be communicated with the external environment of the device housing 100. During sound collection by the sound collection device 300, sound in the external environment of the apparatus housing 100 enters the first chamber 301 through the first connection hole 303 to impact the first surface 311, and finally vibration of the diaphragm 310 is achieved.

The second cavity 302 communicates with a second connection aperture 304, the second connection aperture 304 being isolated from the environment external to the device housing 100. That is, the second cavity 302 does not communicate with the external environment of the device case 100 through the second connection hole 304, and sound in the external environment of the device case 100 cannot directly enter the second cavity 302 through the second connection hole 304.

It should be noted that, in this document, the external environment of the device housing 100 is the environment where the electronic device is located. The sound collecting device 300 collects sounds in the environment in which the electronic device is also located.

The sound collecting device 300 and the sound generating device 200 are both installed in the equipment housing 100 by means of assembly, and the sound collecting device 300 and the sound generating device 200 are respectively matched with the equipment housing 100. The sound emitted from the sound producing device 200 is transmitted directly into the apparatus housing 100 and is picked up by the sound producing device 300 to produce undesirable echoes. Alternatively, the sound emitted from the sound emitting device 200 may be transmitted to the outside of the apparatus casing 100 through the sound emitting channel 210, and then the sound may enter the apparatus casing 100 again through a mounting gap of the electronic apparatus (for example, a mounting gap between the apparatus casing 100 and the display screen, a mounting gap formed by mounting between casing components included in the apparatus casing 100, and the like), and may be picked up by the sound pickup device 300, thereby generating an undesirable echo. The electronic device disclosed in the embodiment of the present application solves the problem of adverse effects caused by sounds which are transmitted into the device housing 100 and picked up by the sound collecting device 300 to generate echoes.

The electronic device disclosed in the embodiment of the present application improves the structure of the electronic device in the related art, by providing the sound collecting device 300 with the first cavity 301 and the second cavity 302 that are isolated from each other, and making the first surface 311 of the diaphragm 310 face the first cavity 301, and the second surface 312 of the diaphragm 310 face the second cavity 302, and then making the sound collecting device 300 be provided with the first connection hole 303 that communicates the first cavity 301 with the external environment of the device housing 100, and the second connection hole 304 that communicates with the second cavity 302 and is isolated from the external environment of the device housing 100, such structure can make the sound transmitted from the sound collecting device 200 into the device housing 100 enter the first cavity 301 and the second cavity 302 through the first connection hole 303 and the second connection hole 304, and make the sound from the sound collecting device 200 enter the first cavity 301 and the second cavity 302, and can respectively drive the first surface 311 and the second surface 312 of the diaphragm 310 to vibrate, thereby achieving the purpose of canceling. In this case, the sound entering the device housing 100 and picked up by the sound pickup device 300 will cancel each other out the action of the diaphragm 310, so that the generation of echo can be alleviated, and finally the adverse effect of the sound pickup device 200 on the sound pickup device 300 can be reduced.

The electronic device disclosed in the embodiment of the present application can prevent all the sound generated by the sound generating device 200 from entering one side of the diaphragm 310, and guide the sound to both sides of the diaphragm 310 (i.e. enter the first cavity 301 and the second cavity 302 respectively) through corresponding structures, so as to offset the sound interference generated by the sound generating device 200 to a certain extent, thereby achieving the purpose of reducing the influence on the sound generating device 300.

It should be noted that, here, a sealing structure may be provided between the sound collecting device 300 and the sound generating device 200 and the apparatus casing 100, so as to achieve a sealed interface of the corresponding structure. However, the sealing of the sealing structure does not completely prevent sound from entering the sound collection device 300. Therefore, in the electronic device disclosed in the embodiment of the present application, the sound emitted from the sound generating device 200 and entering into the device housing 100 enters into the first cavity 301 and the second cavity 302 through the first connecting hole 303 and the second connecting hole 304, respectively, and finally performs a balance cancellation effect.

As described above, the sound collecting device 300 has the first cavity 301 and the second cavity 302, and there are various ways for the sound collecting device 300 to have the first cavity 301 and the second cavity 302. Referring to fig. 1, in a specific embodiment, the sound collecting device 300 may further include a device housing 320 and a cylindrical base 330. The first connection hole 303 and the second connection hole 304 are opened on the device case 320.

A first port of the cylindrical base 330 is connected to an inner wall of the device housing 320, and the diaphragm 310 is disposed at a second port of the cylindrical base 330 and covers the second port. In this case, a region surrounded by the cylindrical base 330 in the inner wall of the device case 320 is a first region, and a region located outside the cylindrical base 330 in the inner wall of the device case 320 is a second region. The first surface 311, the inner wall of the cylindrical base 330 and the first region enclose a first cavity 301, and the first connection hole 303 is opened in the first region. The second surface 312, the outer wall of the cylindrical base 330 and the second area enclose a second cavity 302, and the second connection hole 304 is opened in the second area.

In the sound collecting device 300 having such a structure, the cylindrical base 330 is used to provide a mounting base for the diaphragm 310, and at the same time, the cylindrical base 330 has a cylindrical structure, so that the first chamber 301 can be easily formed with the diaphragm 310 and the device case 320. This configuration advantageously allows the sound collection device 300 to use fewer components to form the first cavity 301.

Meanwhile, since the first connection hole 303 is opened in the first region surrounded by the cylindrical base 330, that is, the region surrounded by the edge of the first port of the cylindrical base 330, and the diaphragm 310 is covered on the second port of the cylindrical base 330, it is easier to implement the first connection hole 303 toward the diaphragm 310. Under the condition, in the sound collecting process, sound entering the first cavity 301 through the first connecting hole 303 easily generates obvious impact on the diaphragm 310, so that the vibration of the diaphragm 310 is obvious, and a good sound collecting effect is achieved. In an alternative, the axis of the first connection hole 303 and the diaphragm 310 may be perpendicular. Of course, the angle between the axis of the first connection hole 303 and the diaphragm 310 may also be about 90 °. In other embodiments, the axis of the first connection hole 303 may form an acute angle with the diaphragm 310. For example, the angle between the axis of the first connection hole 303 and the diaphragm 310 may be 85 ° to 90 °.

Referring to fig. 2, in the sound collecting device 300 with another structure disclosed in the embodiment of the present application, the disclosed sound collecting device 300 may further include a device housing 320, and a first seat 340 and a second seat 350 disposed in the device housing 320. The first connection hole 303 and the second connection hole 304 are opened on the device case 320.

The diaphragm 310 is disposed between the first seat 340 and the second seat 350. Specifically, the first seat 340 and the second seat 350 may be fixed inside the device housing 320, and the diaphragm 310 is clamped and fixed between the first seat 340 and the second seat 350. In this case, the first surface 311, the first holder 340, and a portion of the inner wall of the device housing 320 form the first cavity 301. The second surface 312, the second body 350 and a portion of the inner wall of the device housing 320 define a second cavity 302. In this way, the sizes of the first fastening body 340 and the second fastening body 350 can be flexibly adjusted by the way that the first fastening body 340 and the second fastening body 350 are respectively matched with the first surface 311 and the second surface 312, and thus the sizes of the first cavity 301 and the second cavity 302 can be more flexibly adjusted.

In a further technical scheme, the volumes of the first cavity 301 and the second cavity 302 are equal, so that a balanced structure can be formed, and the air flow in the first cavity 301 and the second cavity 302 can counteract the vibration interference generated by the diaphragm 310, thereby better eliminating echo.

In a further technical solution, the first connection hole 303 and the second connection hole 304 may be symmetrically disposed on two sides of the diaphragm 310, so as to also facilitate the air flow on the two sides of the diaphragm 310 to counteract the vibration generated by the diaphragm 310, and further better eliminate the echo.

In an alternative arrangement, the orientation of the inner port of the first connection hole 303 adjacent to the first cavity 301 is parallel to the first surface 311. The orientation of the interior side port of the second connection aperture 304 adjacent the second lumen 302 may be parallel to the second surface. With the structure, excessive front impact on the diaphragm 310 caused by airflow entering from the first connection hole 303 and the second connection hole 304 can be avoided, and the purpose of protecting the diaphragm is achieved. Of course, this structure can also alleviate dust falling of the diaphragm 310.

In the embodiment of the present application, the structure of the device housing 320 may be various, and in an alternative, the device housing 320 may include a base 321 and a cover 322, and the cover 322 is disposed on the base 321. Both the first connection hole 303 and the second connection hole 304 may be opened on the substrate 321. Specifically, the cover 322 may be fixed to the substrate 321 by bonding, clamping, or the like. In a further aspect, the enclosure 322 can be a shielded enclosure. In this case, the cover 322 not only functions as the component case 320 but also functions as a shield, and thus can prevent electromagnetic interference from the external environment to the internal components of the sound collecting device 300.

Specifically, the sound collecting device 300 disclosed in the embodiment of the present application may further include a processing chip 400, and the processing chip 400 may be mounted on the substrate 321 and located in the casing 322, in which case, the processing chip 400 not only can be protected by the casing 322, but also can shield external electromagnetic interference through the casing 322.

In an alternative solution, the electronic device disclosed in the embodiment of the present application may further include a circuit board 500, and the sound collecting device 300 and the sound generating device 200 may be mounted on the circuit board 500. The circuit board 500 can provide not only a mounting location for the sound collecting device 300 and the sound generating device 200, but also power for the sound collecting device 300 and the sound generating device 200. Specifically, the substrate 321 may be attached to the circuit board 500, thereby improving the stability of the mounting.

Under the condition that the first connection hole 303 and the second connection hole 304 are opened on the substrate 321, the circuit board 500 may be opened with a first avoiding hole 501 and a second avoiding hole 502. The first connection hole 303 communicates with the external environment of the device case 100 through the first avoidance hole 501. Specifically, the first connection hole 303, the first avoiding hole 501, the first sound pickup hole 101 and the external environment are sequentially communicated. The second connection hole 304 communicates with the second avoidance hole 502, and an orifice of the second avoidance hole 502 may be blocked by an inner side surface of the device case 100. In this case, the circuit board 500, the substrate 321 and the device housing 100 are easy to form the same assembly structure, so as to be more beneficial to forming a symmetrical balance structure with the same sealing conditions, and to offset the sound interference, thereby further achieving the purpose of reducing the echo.

As mentioned above, the sound generating device 200 is disposed inside the device housing 100, and the device housing 100 may be provided with the sound generating channel 210 mentioned above for facilitating sound generation of the electronic device. Similarly, the sound collecting device 300 is disposed inside the device housing 100, for collecting sound conveniently, the device housing 100 may be formed with a sound collecting hole 101, and the first connection hole 303 is communicated with an external environment of the device housing 100 through the sound collecting hole 101. In a further technical scheme, the equipment casing 100 may further be provided with a balance hole 102, the balance hole 102 is communicated with the second connection hole 304, and the balance hole 102 is isolated from an external environment of the equipment casing 100. The balance hole 102 can substantially perform an expansion function, so as to prevent the second chamber 302 from generating too large impact on the diaphragm 310 due to too small volume and airflow entering the second connection hole 304, so that the second chamber 302 has a function of balancing and offsetting the vibration of the diaphragm 310.

Of course, the device housing 100 may not need to be provided with the balance hole 102, and the outer opening of the second connection hole 304 may be directly blocked by the inner wall of the device housing 100, so as to achieve the purpose of isolation from the external environment of the device housing 100.

The balance hole 102 is isolated from the external environment of the device housing 100. The structure for achieving the purpose can be various, and in an alternative scheme, the balance hole 102 can be a blind hole, and an open end of the balance hole 102 is in sealed butt joint with and is communicated with the second connecting hole 304. One end of the blind hole does not need to be bored, so that the uniformity of the appearance of the device case 100 can be well ensured.

Of course, in other embodiments, the balance hole 102 may be a through hole, and the first port of the through hole is in sealed abutment with and communicates with the second connection hole 304. The second port of the through hole is provided with a sealing 103, by which the through hole may be isolated from the environment outside the device housing 100. Specifically, the sealing portion 103 may be a sealing plug (e.g., a rubber plug). In this case, in the process of forming the balance hole 102, an operator may first machine a through hole, and then install the sealing portion 103 at the outer end (i.e., the second end) of the through hole.

In a further aspect, the balance hole 102 and the sound pickup hole 101 may be arranged in a first direction, the first direction is a thickness direction of the electronic device, the sound generating device 200 and the sound pickup device 300 may be arranged in a second direction, the first direction is perpendicular to the second direction, the first connection hole 303 and the second connection hole 304 are symmetrically disposed on two sides of a first center line, and the first center line is a center line extending along the second direction of the sound generating device 200. In this case, it is advantageous to form a more symmetrical structure, which in turn facilitates the cancellation of sound.

In the case that the equipment housing 100 is provided with the balance hole 102 and the sound pickup hole 101, in a further aspect, the balance hole 102 and the sound pickup hole 101 may also be symmetrically provided on both sides of the first center line. The structure can ensure that the balance hole 102 and the sound pickup hole 101 are symmetrically distributed on the sound production device 200, so that sound transmitted into the equipment shell 100 can enter the sound production device 300 through a more balanced path, and the balance offset is favorably realized.

In the embodiment of the present application, the electronic device is generally configured with a display screen, the display screen is mounted on the device housing 100, and the thickness direction of the electronic device may be perpendicular to the display surface of the display screen.

The electronic device disclosed in the application embodiment can be a mobile phone, a computer, an electronic book reader, a medical device and the like, and the specific type of the electronic device is not limited in the application embodiment.
