Description

Technical Field

[0001] This utility model relates to the field of audio technology, and in particular to an audio module and electronic device. Background Technology

[0002] Audio modules can emit sound / music and are commonly used in electronic devices such as mobile phones, tablets, computers, and cars.

[0003] Traditional audio modules typically consist of a housing and a sound-generating unit (including coils / magnets) housed within it. Since the housing is usually made of plastic, and plastic housings are difficult to make thin while maintaining strength, steel sheets are used and integrally molded with the plastic housing to increase strength and reduce thickness. However, this results in static electricity easily forming between the steel sheet and the magnetic circuit of the sound-generating unit, necessitating grounding the steel sheet.

[0004] However, due to the limited space in electronic devices, the grounding method of the steel plate in existing audio modules is relatively complex, resulting in the audio module occupying a large amount of space in electronic devices. Utility Model Content

[0005] This utility model provides an audio module and electronic device that can solve the problem of large space occupation of audio modules in the prior art. The technical solution is as follows:

[0006] On one hand, an audio module is provided, including: a bracket, a first conductive sheet, a second conductive sheet, and a sound-generating unit. The sound-generating unit is disposed on the bracket; the first conductive sheet and the second conductive sheet are disposed opposite to each other on both sides of the bracket in a first direction, and the first conductive sheet and the second conductive sheet are located on the same side of the sound-generating unit on the bracket, forming a first cavity together with the bracket. The first conductive sheet is used for grounding, and the second conductive sheet is electrically connected to the first conductive sheet and grounded through the first conductive sheet.

[0007] Since the first conductive plate in the audio module can be used for grounding, while the second conductive plate itself cannot be directly grounded, this application achieves grounding through the first conductive plate by electrically connecting the second conductive plate to the first conductive plate. Therefore, when grounding the second conductive plate, this application does not require additional components (such as conductive copper foil, conductive foam, conductive springs, etc.), but utilizes the existing structure of the audio module for grounding. Compared with existing technologies, this not only reduces the number of components in the audio module, lowers process complexity and cost, but also reduces the space occupied by the audio module in the electronic device.

[0008] In some possible implementations, the first conductive sheet includes a first main body portion, a ground portion, and a connecting portion connected together. The first main body portion and the ground portion are attached to the side of the bracket opposite to the second conductive sheet, and the ground portion is used for grounding. The connecting portion protrudes from the first main body portion along the first direction, and the connecting portion passes through the bracket and protrudes from the side facing the second conductive sheet to be electrically connected to the second conductive sheet.

[0009] By attaching the first main body and the grounding part to the side of the bracket away from the second conductive sheet, and passing the connecting part from one side of the bracket to the other side, the connection strength between the first conductive sheet and the bracket can be improved while realizing the electrical connection between the first conductive sheet and the second conductive sheet, thereby helping to improve the overall strength of the bracket.

[0010] In some possible implementations, the connecting portion has a first surface in the first direction, the first surface being exposed from the side of the bracket facing the second conductive sheet; the first surface is abutting against the second surface of the second conductive sheet facing the connecting portion in the first direction.

[0011] By attaching the first surface and the second surface face to face in the first direction, the contact area between the first conductive sheet and the second conductive sheet can be guaranteed, thereby improving the reliability of the electrical connection between the first conductive sheet and the second conductive sheet.

[0012] In some possible implementations, the connecting portion includes a connecting piece and an adapter that are interconnected. The connecting piece is disposed facing the second conductive sheet in the first direction, and the first surface is disposed on the connecting piece; the connecting piece is connected to the first main body portion and / or the grounding portion via the adapter.

[0013] In some possible implementations, the first conductive sheet includes two connecting portions and two grounding portions, wherein the two connecting portions are respectively a first connecting portion and a second connecting portion, and the two grounding portions are respectively a first grounding portion and a second grounding portion. Specifically, the connecting piece in the first connecting portion is connected to the first main body portion via the adapter and is also connected to the first grounding portion. The connecting piece in the second connecting portion is connected to the second grounding portion via the adapter, and the second grounding portion is connected to the first main body portion.

[0014] The adapter in the first connecting portion includes a first adapter piece and a second adapter piece; the first adapter piece and the second adapter piece are disposed opposite each other on both sides of the connecting piece. The connecting piece is connected to the first main body portion via the first adapter piece and to the grounding portion via the second adapter piece.

[0015] Here, by passing the first adapter piece and the second adapter piece through the bracket respectively, the first surface of the connecting piece in the first connecting part is exposed to the bracket, which can increase the reliability of the connection between the first connecting part and the bracket, thereby enhancing the strength of the bracket.

[0016] In some possible implementations, the adapter in the second connection portion is a sheet-like structure, and both ends of the adapter in the second connection portion are respectively connected to the connecting piece and the second grounding portion in the second connection portion.

[0017] In some possible implementations, the connecting portion is connected to the first body portion at the outer edge of the first body portion, and the connecting portion is attached to the outer edge of the second conductive sheet.

[0018] Here, since the connecting part is located at the outer edge of the first main body, after the first conductive sheet and the bracket are formed, the second conductive sheet can be placed on the bracket, and the outer edge of the second conductive sheet can face the corresponding surface of the connecting part and be attached, which facilitates the connection between the first conductive sheet and the second conductive sheet during the welding process.

[0019] In some possible implementations, the first conductive sheet includes two connecting portions and two grounding portions. The two connecting portions are plate-shaped structures disposed perpendicular to the first main body portion and are respectively the third connecting portion and the fourth connecting portion. The two grounding portions are respectively the third grounding portion and the fourth grounding portion.

[0020] The third connecting portion is located on one side of the outer edge of the first main body in the second direction and is connected to the first main body. The third surface of the third connecting portion facing the second conductive sheet in the second direction is abutted against the outer edge of the second conductive sheet. The fourth connecting portion is located on one side of the outer edge of the first main body in the third direction and is connected to the fourth grounding portion. The fourth surface of the fourth connecting portion facing the second conductive sheet in the third direction is abutted against the outer edge of the second conductive sheet. The second direction and the third direction are different and both intersect with the first direction.

[0021] Here, by connecting the two connecting parts in different directions to the second conductive sheet, the reliability of the electrical connection between the first and second conductive sheets can be improved.

[0022] In some possible implementations, the grounding part is provided with a grounding hole, through which the first conductive piece is grounded.

[0023] On the other hand, an electronic device is provided, which integrates any of the audio modules described above. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0032] This application provides an audio module that can be used as an audio module in an electronic device. Here, the electronic device can be a mobile phone, tablet, computer, automobile, etc. This application does not limit the scope of the application.

[0033] Please refer to Figure 1 and Figure 2 , Figure 1 This is a three-dimensional structural diagram of an audio module provided in an embodiment of this application from one perspective. Figure 2 This is a three-dimensional structural diagram of an audio module provided in an embodiment of this application from another perspective. The audio module 000 may include: a support 10, a first conductive sheet 20, a second conductive sheet 30, and a sound-emitting unit 40.

[0034] The sound-generating unit 40 is fixedly mounted on the bracket 10, which serves as the supporting component for the sound-generating unit 40 and can be made of plastic. The sound-generating unit 40, as the sound-generating component of the audio module 000, can specifically include a coil, a magnet, and a vibrating plate. When the sound-generating unit 40 receives an audio signal, and the audio signal passes through the coil, the change in current generates an alternating magnetic field. This alternating magnetic field interacts with the magnetic field of the magnet, causing the coil to drive the vibrating plate to vibrate reciprocally. The reciprocating vibration of the vibrating plate can push air molecules, thereby forming and propagating sound waves. Of course, the sound-generating unit 40 can also have other structures; this application embodiment does not limit the specific structure of the sound-generating unit 40.

[0035] The first conductive sheet 20 and the second conductive sheet 30 are disposed opposite each other on the support 10 in a first direction L1, which is parallel to the thickness direction of the support 10. The first conductive sheet 20 and the second conductive sheet 30 are located on the same side of the sound-emitting unit 40 on the support 10, and together with the support 10, they form a first cavity C1. The first cavity C1 can absorb the sound waves emitted by the sound-emitting unit 40, thereby optimizing the sound output to the audio module 000 through the sound-emitting unit 40.

[0036] Furthermore, since the first conductive sheet 20 and the second conductive sheet 30 are disposed on both sides of the bracket 10 in the first direction L1, the strength of the bracket 10 can be improved and the thickness of the bracket 10 can be reduced. It also helps to increase the volume of the first cavity C1, thereby further optimizing the sound output to the audio module 000 through the sound unit 40.

[0037] The first conductive sheet 20 is used for grounding, and the second conductive sheet 30 is electrically connected to the first conductive sheet 20 and grounded through the first conductive sheet 20. Here, the first conductive sheet 20 can be grounded by directly setting a grounding point, or it can be grounded through conductive copper foil, conductive foam, conductive spring, etc. This application embodiment does not limit the specific grounding method of the first conductive sheet 20. The second conductive sheet 30 itself cannot be grounded, but is grounded through the first conductive sheet 20.

[0038] The first conductive sheet 20 and the second conductive sheet 30 can be metal sheets, such as steel sheets. The first conductive sheet 20 can be integrally formed with the bracket 10, and the second conductive sheet 30 can abut or be welded to the first conductive sheet 20.

[0039] In related technologies, the first conductive sheet in the audio module is grounded. However, when the second conductive sheet cannot be grounded, it is necessary to connect it by adding conductive copper foil, conductive foam, conductive spring, etc. This not only increases the number of components in the audio module, complicates the process, and increases the cost, but also increases the space occupied by the audio module in the electronic device.

[0040] In this embodiment, since the first conductive sheet 20 in the audio module 000 can be used for grounding, and the second conductive sheet 30 itself cannot be directly grounded, this application achieves grounding through the first conductive sheet 20 by electrically connecting the second conductive sheet 30 to the first conductive sheet 20. Therefore, when grounding the second conductive sheet 30, this application does not require additional components (such as conductive copper foil, conductive foam, conductive springs, etc.), but utilizes the existing structure on the audio module 000 to achieve grounding. Compared with the prior art, this not only reduces the number of components in the audio module 000, lowers the process complexity and cost, but also reduces the space occupied by the audio module 000 in the electronic device.

[0041] In one possible implementation, such as Figure 1 and Figure 2 As shown, a second cavity C2 communicating with the first cavity C1 is also formed on the support 10, and a sound-emitting channel V is provided on the side wall of the second cavity C2. The sound-emitting unit 40 is disposed in the second cavity C2 and outputs sound outward through the sound-emitting channel V. In addition, after the sound-emitting unit 40 is disposed in the second cavity C2, a cover plate (not shown) can also be provided, which cooperates with the support 10 to encapsulate the sound-emitting unit 40 in the second cavity C2.

[0042] Please refer to Figure 3 and Figure 4 , Figure 3 This is a schematic diagram illustrating the connection between a first conductive sheet and a second conductive sheet according to an embodiment of this application. Figure 4 This is a schematic diagram of another connection between a first conductive sheet and a second conductive sheet provided in an embodiment of this application. The first conductive sheet 20 includes a first main body portion 21, a grounding portion 22, and a connecting portion 23 that are connected to each other.

[0043] It should be noted that the grounding portion 22 can be directly connected to the first main body portion 21, or it can be connected to the first main body portion 21 through the connecting portion 23. Similarly, the connecting portion 23 can be directly connected to the first main body portion 21, or it can be connected to the first main body portion 21 through the grounding portion 22. Of course, the connecting portion 23 and the grounding portion 22 can also be directly connected to different parts of the first main body portion 21, respectively. This application embodiment does not limit this.

[0044] The first main body portion 21 and the grounding portion 22 are attached to the side of the bracket 10 facing away from the second conductive sheet 30, and the grounding portion 22 is used for grounding. The connecting portion 23 protrudes from the first main body portion 21 along the first direction L1, and the connecting portion 23 passes through the bracket 10 and protrudes from the side facing the second conductive sheet 30, so as to be electrically connected to the second conductive sheet 30. That is, the first main body portion 21 and the grounding portion 22 are spaced apart from the second conductive sheet 30 in the first direction L1, and the connecting portion 23 is located between the first main body portion 21, the grounding portion 22 and the second conductive sheet 30 in the first direction L1.

[0045] Understandably, the number of grounding portions 22 and connecting portions 23 can be set according to the actual product usage requirements. The accompanying drawings in this application embodiment illustrate an example where the first conductive sheet 20 includes two grounding portions 22 and two connecting portions 23. In other possible implementations, the first conductive sheet 20 may also include one grounding portion 22 and one connecting portion 23, or the first conductive sheet 20 may include more grounding portions 22 and connecting portions 23, for example, three, four, or five. This application embodiment does not limit this.

[0046] In this embodiment, by attaching the first main body 21 and the grounding part 22 to the side of the bracket 10 away from the second conductive sheet 30, and by passing the connecting part 23 from one side of the bracket 10 to the other side, the connection strength between the first conductive sheet 20 and the second conductive sheet 30 can be improved while realizing the electrical connection between the first conductive sheet 20 and the bracket 10, thereby helping to improve the overall strength of the bracket 10.

[0047] Here, there are various ways to electrically connect the connecting portion 23 in the first conductive sheet 30 to the second conductive sheet 30. This application embodiment will illustrate with the following two exemplary implementation methods.

[0048] In the first exemplary implementation, such as Figure 3 and Figure 5 As shown, Figure 5 for Figure 3 The diagram illustrates the connection between the first conductive sheet and the support. The connecting portion 23 has a first surface S1 in the first direction L1. The first surface S1 protrudes from the side of the support 10 facing the second conductive sheet 30. The first surface S1 and the second surface S2 of the second conductive sheet 30 are attached to each other in the first direction L1, facing the connecting portion 23. That is, the first surface S1 and the second surface S2 are attached face-to-face in the first direction L1.

[0049] It should be noted that the bonding in this application can be a surface-to-surface contact (e.g., abutment) electrical connection or a welding electrical connection. For example, the first surface S1 on the connecting portion 23 is welded to the second surface S2 on the second conductive sheet 30, wherein... Figure 5G1 and G2 are the laser welding areas.

[0050] In order to expose the first surface S1 of the connecting part 23 from the side of the bracket 10 facing the second conductive sheet 30, the bracket 10 is provided with a through hole for the corresponding part of the connecting part 23 to pass through.

[0051] In this embodiment, by attaching the first surface S1 and the second surface S2 face to face in the first direction L1, the contact area between the first conductive sheet 20 and the second conductive sheet 30 can be guaranteed, thereby improving the reliability of the electrical connection between the first conductive sheet 20 and the second conductive sheet 30.

[0052] Please refer to Figure 3 The connecting portion 23 includes a connecting piece 231 and an adapter 232 that are interconnected. The connecting piece 231 is disposed facing the second conductive sheet 30 in a first direction L1, and a first surface S1 is disposed on the connecting piece 231. The connecting piece 231 is connected to the first main body portion 21 and / or the grounding portion 22 via the adapter 232.

[0053] Here, the adapter 232 passes through the bracket 10, and the connecting piece 231 can extend partially or completely from the side of the bracket 10 facing the second conductive piece 30, so that the first surface S1 is exposed on the bracket 10. Alternatively, the connecting piece 231 can be flush with the corresponding surface portion of the bracket 10 on the side facing the second conductive piece 30, so that the first surface S1 is exposed on the bracket 10. This embodiment does not limit this arrangement.

[0054] Please refer to Figure 3 The first conductive sheet 20 includes two connecting portions 23 and two grounding portions 22. The two connecting portions 23 are electrically connected to the second conductive sheet 30 respectively, which can improve the reliability of the electrical connection between the first conductive sheet 20 and the second conductive sheet 30; while the two grounding portions 22 are grounded respectively, which can improve the grounding stability of the first conductive sheet 20.

[0055] The two connecting portions 23 are respectively the first connecting portion 23A and the second connecting portion 23B, and the two grounding portions 22 are respectively the first grounding portion 22A and the second grounding portion 22B. The connecting piece 231 in the first connecting portion 23A is connected to the first main body portion 21 via an adapter 232, and is also connected to the first grounding portion 22A. The connecting piece 231 in the second connecting portion 23B is connected to the second grounding portion 22B via an adapter 232, and the second grounding portion 22B is connected to the first main body portion 21.

[0056] Here, both the first connecting part 23A and the second connecting part 23B are electrically connected to the second conductive piece 30 through corresponding connecting pieces 231, and the connecting pieces 231 are electrically connected to the grounding part 22 through the adapter 232. That is, both the first connecting part 23A and the second connecting part 23B are located close to the corresponding grounding part 22, which makes the grounding path of the second conductive piece 30 shorter, thereby improving the grounding stability of the second conductive piece 30.

[0057] Please refer to Figure 3 The adapter 232 in the first connecting portion 23A further includes a first adapter piece 2321 and a second adapter piece 2322, which are disposed opposite to each other on both sides of the connecting piece 231. The connecting piece 231 in the first connecting portion 23A is connected to the first main body portion 21 via the first adapter piece 2321, and is connected to the first grounding portion 22A via the second adapter piece 2322.

[0058] Here, the first connecting part 23A is disposed between the first main body part 21 and the first grounding part 22A, and is connected to the first main body part 21 and the first grounding part 22A respectively through the first adapter piece 2321 and the second adapter piece 2322 of the adapter 232.

[0059] The first adapter piece 2321 and the second adapter piece 2322 are respectively installed through the bracket 10 so that the first surface S1 on the connecting piece 231 in the first connecting part 23A is exposed to the bracket 10. This can increase the reliability of the connection between the first connecting part 23A and the bracket 10, thereby enhancing the strength of the bracket 10.

[0060] Please refer to Figure 3 The adapter 232 in the second connecting part 23B has a sheet-like structure, and both ends of the adapter 232 in the second connecting part 23B are respectively connected to the connecting piece 231 and the second grounding part 22B in the second connecting part 23B.

[0061] In the second exemplary implementation, such as Figure 4 and Figure 6 As shown, Figure 6 for Figure 4 The diagram shows the connection between the first conductive sheet and the bracket. The connecting part 23 is connected to the first main body 21 at the outer edge of the first main body 21, and the connecting part 23 is attached to the outer edge of the second conductive sheet 30.

[0062] Here, since the connecting part 23 is located at the outer edge of the first main body 21, after the first conductive sheet 20 and the bracket 10 are formed, the second conductive sheet 30 can be placed on the bracket 10, and the outer edge of the second conductive sheet 30 can face the corresponding surface of the connecting part 23 and be attached, which facilitates the connection between the first conductive sheet 20 and the second conductive sheet 30 during the welding process.

[0063] Please refer to Figure 4 The first conductive sheet 20 includes two connecting portions 23 and two grounding portions 22. The two connecting portions 23 are plate-shaped structures that are perpendicular to the first main body portion 21, and are respectively the third connecting portion 23C and the fourth connecting portion 23D. The two grounding portions 22 are respectively the third grounding portion 22C and the fourth grounding portion 22D.

[0064] The third connecting portion 23C is located on the outer edge side of the first main body portion 21 in the second direction L2 and is connected to the portion of the first main body portion 21 near the third grounding portion 22C. The third surface S3 of the third connecting portion 23C facing the second conductive sheet 30 in the second direction L2 is attached to the outer edge of the second conductive sheet 30.

[0065] The fourth connecting portion 23D is located on the outer edge side of the first main body portion 21 on the third direction L3 and is connected to the fourth grounding portion 22D. The fourth surface S4 of the fourth connecting portion 23D facing the second conductive sheet 30 on the third direction L3 is attached to the outer edge of the second conductive sheet 30.

[0066] In this example, the second direction L2 and the third direction L3 are different directions, and both intersect the first direction L1. The first direction L1, the second direction L2, and the third direction L3 are all perpendicular to each other.

[0067] In this embodiment, by connecting the two connecting portions 23 to the second conductive sheet 30 in different directions, the reliability of the electrical connection between the first conductive sheet 20 and the second conductive sheet 30 can be improved.

[0068] In some embodiments, please refer to Figure 3 and Figure 4 The grounding part 22 is provided with a grounding hole T, and the first conductive piece 20 is used to ground through the grounding hole T. Here, taking the audio module on a mobile phone as an example, in order to connect the bracket 10 and the middle frame of the mobile phone, bolt holes need to be provided on the bracket 10, and the grounding hole T on the grounding part 22 is set corresponding to the bolt holes of the bracket 10. In this way, the bracket 10 and the middle frame of the mobile phone can be connected by a locking component (such as a bolt) passing through the bolt hole and the grounding hole T, and the grounding of the grounding hole T is achieved through the locking component and the middle frame.

[0069] In some embodiments, please refer to Figure 3 and Figure 4 The first conductive sheet 20 also includes an extension 24, which protrudes along a first direction L1 and is disposed at the edge of the first main body portion 21 and / or the connecting portion 23. The extension 24 is disposed through at least a portion of the bracket 10, and the connection reliability between the first conductive sheet 20 and the bracket 10 can be improved by the extension 24.

[0070] In some embodiments, please refer to Figure 3 and Figure 4 The second conductive sheet 30 includes: a second main body 31, a first eaves 32, and a second eaves 33.

[0071] The first eaves 32 and the second eaves 33 are disposed on the edge portion of the second main body 31, with the first eaves 32 disposed on one side of the second main body 31 in the second direction L2, and the second eaves 33 disposed on one side of the second main body 31 in the third direction L3. The first eaves 32 and the second eaves 33 are respectively connected to the corresponding connecting portions 23.

[0072] In some embodiments, please refer to Figure 1 and Figure 2 The audio module 000 also includes a third conductive sheet 50 and a fourth conductive sheet 60, which are disposed on the side of the bracket 10 away from the sound-generating unit 40 and on both sides of the second conductive sheet 30. The third conductive sheet 50 and the fourth conductive sheet 60 can be integrally formed with the bracket 10. The arrangement of the third conductive sheet 50 and the fourth conductive sheet 60 further improves the strength of the bracket 10.
