[0059] Figure 1 is a structural diagram of a speaker module 100 according to an exemplary embodiment. Figure 2 yes Figure 1 An exploded diagram of the speaker module 100 is shown. Figure 3 yes Figure 1 A schematic cross-sectional view of the speaker module 100, Figure 4 FIG. 1 is a schematic diagram showing an assembly of a diaphragm 21 and a conductive path 22 according to an exemplary embodiment. Figures 1-4 As shown, the speaker module 100 may include a bracket 1, a diaphragm assembly 2, a magnet 3, and a voice coil 4. The magnet 3 may be fixedly connected to the bracket 1, and by properly positioning the magnets within the magnet 3, the magnet 3 may be arranged to form a magnetic gap. A portion of the voice coil 4 may be disposed within the magnetic gap. Consequently, when the voice coil 4 is subsequently energized, it cuts the magnetic flux lines of the magnet 3, interacting with the magnet 3 and enabling the voice coil 4 to move up and down. The diaphragm assembly 2 may include a diaphragm 21 and a conductive path 22. The diaphragm 21 may be connected to the bracket 1, and the voice coil 4 may be connected to one side of the diaphragm 21. The conductive path 22 may be disposed on the surface of the diaphragm 21, and one end of the conductive path 22 may be electrically connected to the voice coil 4, while the other end may be electrically connected to the audio signal input circuit.
[0060] Based on this, when the audio signal input circuit of the speaker module 100 receives an audio signal, the audio signal can be transmitted to the voice coil 4 through the conductive path 22, causing the voice coil 4 to conduct electricity and interact with the magnetic component 3, causing the voice coil 4 to move up and down, thereby driving the diaphragm 21 to vibrate and produce sound. The conductive path 22 may include a liquefiable conductive medium 221 and a protective layer 222. The liquefiable conductive medium 221 is located between the protective layer 222 and the diaphragm 21. The liquefiable conductive medium 221 may be liquefied before the speaker module 100 switches to the operating state, or it may be liquefied after the speaker module 100 switches to the operating state. This can be achieved by controlling the relationship between the melting point of the liquefiable conductive medium 221 and the operating temperature of the speaker module 100.
[0061] The liquid liquefiable conductive medium 221 can, on the one hand, alleviate the internal stress caused by the vibration of the diaphragm 21, thereby extending the service life of the speaker module 100. Furthermore, the liquid liquefiable conductive medium can conduct any circuit gaps in the conductive path, thereby ensuring that the conductive path is continuous. The protective layer 222 prevents the liquefiable conductive medium 221 from flowing irregularly on the surface of the diaphragm 21, ensuring that the liquefiable conductive medium 221 can conduct electricity between the audio signal input circuit and the voice coil 4 in both liquid and solid states. Furthermore, in the technical solution disclosed herein, the conductive path 22 is disposed on the surface of the diaphragm 21. Compared to the related art solution that uses a skeleton and a circuit board fixed to the skeleton, and conducts electricity between the voice coil 4 and the audio signal input circuit via the circuit board, the structure of the speaker module 100 can be simplified, and the internal space of the speaker module 100 can be expanded. Among them, the liquefiable conductive medium 221 can include silver paste or gallium-based liquid alloy. By utilizing the flexibility, low resistance and low melting point of the gallium-based liquid alloy, the electrical performance of the conductive path 22 can be maintained in harsh environments such as high temperature and high humidity. At the same time, it can also adapt to multiple vibrations of the diaphragm 21 without deformation.
[0062] In this embodiment, the melting point of the liquefiable conductive medium 221 can be less than or equal to the minimum operating temperature of the speaker module 100. For example, the melting point of the liquefiable conductive medium 221 can be adjusted to near room temperature or a lower temperature to ensure that the liquefiable conductive medium 221 is liquefied before the speaker module 100 switches to the operating state, or the liquefiable conductive medium 221 is in a liquid state regardless of whether the speaker module 100 is in the operating state or the non-operating state. In this way, the liquefiable conductive medium 221 melts into a liquid state before the speaker module 100 switches to the operating state. The liquid liquefiable conductive medium 221 can, on the one hand, buffer the stress of the vibration deformation of the diaphragm 21, thereby extending the service life of the speaker module 100. On the other hand, the liquefaction of the liquefiable conductive medium 221 before the speaker module 100 switches to the operating state can avoid the problem of circuit breakage caused by the solidification of the liquefiable conductive medium 221 after the speaker module 100 completes the previous operation. The minimum operating temperature of the speaker module 100 can be determined through a limited number of tests. Alternatively, in other embodiments, the melting point of the liquefiable conductive medium 221 can be greater than the minimum operating temperature of the speaker module 100 and less than the maximum operating temperature of the speaker module 100. This allows the liquefiable conductive medium 221 to liquefy for a period of time after the speaker switches to an operating state, thereby relieving internal stress.
[0063] In the above embodiment, the conductive medium in the conductive pathway 22 disposed on the diaphragm 21 can be a liquefiable conductive medium 221. In this case, the liquefiable conductive medium 221, when liquefied, can provide electrical connection between the voice coil 4 and the audio signal input circuit. If the conductive medium in the conductive pathway 22 can be a liquefiable conductive medium 221, then to avoid the formation of cracks in the liquefiable conductive medium 221 after solidification, which would subsequently prevent the voice coil 4 from being electrically connected, the liquefiable conductive medium 221 can be made of a mixture of a conductive metal medium and a conductive adhesive. The conductive adhesive can be used to bond the solidified conductive metal medium when the liquefiable conductive medium 221 solidifies, so that the liquefiable conductive medium 221 remains conductive after solidification, thereby preventing the speaker module 100 from being unable to start.
[0064] Alternatively, in other embodiments, the conductive path 22 may also include a solid conductive medium, one end of which is electrically connected to the voice coil 4 and the other end to the audio signal input circuit. Before the audio module 100 switches to the operating state, the liquefiable conductive medium 221 may liquefy. The liquid liquefiable conductive medium 221 may flow along the solid conductive medium, allowing the liquid liquefiable conductive medium 221 to flow to any breaks in the solid conductive medium caused by the vibration of the diaphragm 21, filling the gaps and achieving electrical continuity between the audio input circuit and the voice coil 4. In this manner, the liquid liquefiable conductive medium 221 can bridge breaks or cracks in the solid conductive medium caused by stress, ensuring that the conductive path 22 can properly transmit electrical signals. Compared to a solution where electrical conduction is entirely through the liquefiable conductive medium 221, this reduces the amount of liquefiable conductive medium 221 used, resulting in more stable electrical performance.
[0065] like Figure 3 As shown, the diaphragm 21 may include an annular raised portion 211, which may be formed as a protrusion along the thickness direction of the diaphragm 21. The radially inner edge of the annular raised portion 211 on the diaphragm 21 may be connected to the dome 5 of the speaker module 100, and the dome 5 is connected to the voice coil 4. The connection between the voice coil 4 and the diaphragm 21 allows the diaphragm 21 to move relative to the bracket 1 when the diaphragm 21 moves. In other embodiments, the radially inner edge of the annular raised portion 211 on the diaphragm 21 may be directly connected to the voice coil 4, which is not limited in this disclosure. The radially outer edge of the annular raised portion 211 on the diaphragm 21 may be connected to the bracket 1. The conductive path 22 may be provided on the surface of the annular raised portion 211, specifically, on the surface of the annular raised portion 211 near the voice coil 4, to facilitate electrical connection between the conductive path 22 and the voice coil wire of the voice coil 4. The conductive path 22 can be symmetrically arranged on the surface of the annular protrusion 211 along the symmetry center of the diaphragm 21 so that the diaphragm 21 can maintain balance during vibration.
[0066] In the embodiments provided herein, a vibration assembly including a magnet 3 and a voice coil 4 is used as an example for illustration. In other embodiments, the vibration assembly may also include a piezoelectric ceramic. One end of the conductive path 22 may be connected to the piezoelectric ceramic, and the other end may be connected to an audio signal input circuit. In this way, when the audio signal is transmitted to the piezoelectric ceramic through the conductive path 22, the piezoelectric ceramic may be deformed, and the diaphragm 21 may be attached to the piezoelectric ceramic. The deformation of the piezoelectric ceramic then drives the diaphragm 21 to vibrate, thereby producing sound. In the embodiments provided herein, an example is provided in which the conductive path 22 includes a protective layer 222, and the protective layer 222 restricts the flow of a liquid liquefiable conductive medium 221. In other embodiments, a groove may be formed on the surface of the diaphragm 21, and the liquefiable conductive medium 221 may be processed in the groove. The groove restricts the flow of the liquid liquefiable conductive medium 221. The specific design can be as desired, and this disclosure is not limited thereto.
[0067] In the above embodiment, the audio module is described using the speaker module 100 as an example. In other embodiments, the audio module may also include a microphone module. When the audio module includes a microphone module, one end of the conductive path can be electrically connected to the voice coil, and the other end can be connected to the audio output circuit. In this way, the current generated by the voice coil can be output through the audio output circuit, and the user's voice signal can be obtained through processing. In some other embodiments, the audio module may also include an earpiece module, and this disclosure is not limited to this.
[0068] Based on the technical solution of the present disclosure, the present disclosure further provides an electronic device, which may include a housing and a speaker module 100 as described in any of the above embodiments. The housing may include a sound outlet. The speaker module 100 may be disposed within the housing, with the diaphragm 21 disposed toward the sound outlet, so that when the diaphragm 21 vibrates, air vibrates, and sound can be transmitted through the sound outlet. Of course, the electronic device may also include a microphone module and an earpiece module. The structure of at least one of the microphone module and the earpiece module may refer to the structure of the speaker module 100 in the above embodiments.
[0069] like Figure 5 As shown, the present disclosure also provides a method for manufacturing a diaphragm assembly 2, which may include the following steps:
[0070] In step 501 , a diaphragm is obtained.
[0071] In step 502, a conductive path is processed on the surface of the diaphragm to obtain the diaphragm assembly, wherein the conductive path includes a liquefiable conductive medium, and the liquefiable conductive medium is in liquid form when the audio module to which the diaphragm assembly belongs is in working state.
[0072] Thus, by changing the state of the liquefiable conductive medium 221 in the conductive path, it is possible to avoid frequent changes in the internal stress of the conductive path 22 caused by the vibration of the diaphragm 21, which may lead to breakage of the conductive path 22 and damage to the speaker module 100.
[0073] In order to elaborate on the specific production method in this disclosure, Figure 6 As shown:
[0074] In step 601 , a flat membrane is obtained.
[0075] In step 602 , a liquefiable conductive medium 221 is printed on the membrane.
[0076] In this embodiment, the diaphragm can be processed according to the desired shape of the diaphragm 21, and the liquefiable conductive medium 221 can be printed according to the desired position of the conductive path 22. For example, in the present disclosure, the annular protrusion 211 of the diaphragm 21 is located in the middle area of the diaphragm 21, so the liquefiable conductive medium 221 can be printed in the middle area of the diaphragm.
[0077] In step 603 , the membrane is processed so that a portion of the membrane corresponding to the liquefiable conductive medium 221 is raised along the thickness direction of the membrane to form an annular raised portion.
[0078] In this embodiment, the liquefiable conductive medium 221 may be printed on the membrane first, and then when the annular protrusion 211 is formed integrally therewith, the liquefiable conductive medium 221 may be located on the surface of the annular protrusion 211 .
[0079] In step 604 , a protective layer 222 is processed on the annular protrusion 211 , with the liquefiable conductive medium 221 located between the protective layer 222 and the annular protrusion 211 .
[0080] In this embodiment, a protective layer 222 can be sprayed on the surface of the annular protrusion 211, and the liquefiable conductive medium 221 can be positioned between the protective layer 222 and the diaphragm 21. Thus, the protective layer 222 can restrict the flow of the liquefiable conductive medium 221 when in liquid form. The protective layer 222 can include a protective adhesive layer or other protective flexible layer to prevent the protective layer 222 from breaking during vibration of the diaphragm 21 and thereby failing to restrict the flow of the liquefiable conductive medium 221.
[0081] In some other embodiments, before forming the annular protrusion 211, a protective layer 222 may be processed on the surface of the liquefiable conductive medium 221, and the liquefiable conductive medium 221 may be located between the diaphragm and the protective layer 222. When the annular protrusion 211 is subsequently processed, the liquefiable conductive medium 221 and the protective layer 222 located on the surface of the annular protrusion 211 may be formed simultaneously.
[0082] In step 605, the diaphragm assembly 2 is obtained.
[0083] In another embodiment, Figure 7 As shown, the manufacturing method of the diaphragm assembly 2 may include:
[0084] In step 701 , a flat membrane is obtained.
[0085] In step 702 , the diaphragm is processed so that the diaphragm is raised in the thickness direction to form an annular raised portion 211 , thereby obtaining the diaphragm 21 .
[0086] In step 703 , a liquefiable conductive medium 221 is printed on the surface of the annular protrusion 211 .
[0087] In step 704 , a protective layer 222 is processed on the surface of the liquefiable conductive medium 221 so that the liquefiable conductive medium 221 is located between the protective layer 222 and the annular protrusion 211 .
[0088] In this embodiment, the diaphragm can be processed to obtain the annular protrusion 211, and then the surface of the annular protrusion 211 is printed with a liquefiable conductive medium 221 and a sprayed protective layer 222. Figure 6 The illustrated embodiment can more accurately determine the position of the conductive path 22 , thereby improving the processing yield of the speaker module 100 .
[0089] In step 705, the diaphragm assembly 2 is obtained.
