[0042] At present, speakers are widely used in various fields such as mobile phones, televisions and automobiles. Moreover, as people pursue lightweight products, speakers are also designed to be more and more miniaturized.

[0043] In the related art, two, three or more mounting points are usually set on the speaker frame so that the speaker can be installed on the mounting part. However, the more mounting points there are, the more space is needed, which is not conducive to the miniaturization of the speaker and the electronic device.

[0044] Based on the above problem, the present invention provides a speaker module 100 .

[0045] See also Figures 1 to 4 In one embodiment of the present invention, the speaker module 100 includes a speaker 1, a fixing component 2 and a locking member 3. The speaker 1 is provided with a magnetic conductive member 121. The side of the magnetic conductive member 121 facing away from the diaphragm 131 is provided with a fixing hole 1213; the fixing component 2 includes a connecting rod 21 and an expansion module 22 connected to each other. The expansion module 22 is arranged in the fixing hole 1213 and abuts against the hole wall of the fixing hole 1213 to form a circumferential support for the speaker 1; the locking member 3 is connected to a portion of the connecting rod 21 located outside the fixing hole 1213.

[0046] When the speaker module 100 is fixed to the mounting bracket 200 , the connecting rod 21 penetrates the mounting bracket 200 , and the locking member 3 and the magnetic conductive member 121 respectively abut against two side surfaces of the mounting bracket 200 that are arranged opposite to each other.

[0047] In an embodiment of the present application, the speaker module 100 is used in electronic devices such as automobiles, speakers, mobile phones, televisions, VR devices (Virtual Reality), AR devices (Augmented Reality) and MR devices (Mixed Reality). The electronic device is provided with a mounting bracket 200 for mounting the speaker module 100. The mounting bracket 200 can be a housing of the electronic device or a structural member provided in the electronic device for mounting the speaker 1. The mounting bracket 200 is provided with a mounting hole 201.

[0048] The speaker 1 in the speaker module 100 includes a basket 11, a vibration system 13 and a magnetic circuit system 12. The vibration system 13 includes a diaphragm 131 and a voice coil 132. The diaphragm 131 is arranged at the opening position of the basket 11; the magnetic circuit system 12 includes a magnetic conductive member 121 and a magnet 122. The magnetic conductive member 121 is arranged on the rear side of the basket 11. The magnetic conductive member 121 includes a central portion 1211 and an edge portion 1212. The central portion 1211 is inserted into the basket 11 and is provided with a fixing hole 1213. The edge portion 1212 is located on the outside of the basket 11 and is used to fix the magnet 122. A magnetic gap is formed between the magnet and the central portion 1211 for cooperating with the voice coil 132 of the vibration system 13. When installing the speaker 1, the fixing hole 1213 is coaxially arranged with the mounting hole 201 of the mounting bracket 200.

[0049] The speaker module 100 also includes a fixing component 2 and a locking piece 3, the fixing component 2 includes a connecting rod 21 and an expansion module 22, the expansion module 22 and the locking piece 3 are both connected to the connecting rod 21, wherein the expansion module 22 is inserted into the fixing hole 1213 of the speaker 1 and abuts against the hole wall of the fixing hole 1213, so that the expansion module 22 and the magnetic conductive piece 121 are tightly fitted and connected to each other; optionally, the expansion module 22 can be set to a cylindrical structure adapted to the shape of the fixing hole 1213, the expansion module 22 is inserted into the fixing hole 1213 and has an interference fit with the fixing hole 1213; the expansion module 22 can also be set to an expandable and retractable structure in the following embodiment.

[0050] When installing the speaker 1, the connecting rod 21 is passed through the mounting hole 201, the magnetic conductive member 121 of the speaker 1 is abutted against the mounting bracket 200, the locking member 3 is locked and fixed with the connecting rod 21, and the locking member 3 is abutted against the side of the mounting bracket 200 away from the speaker 1. Such a configuration is equivalent to the locking member 3 and the magnetic conductive member 121 clamping the mounting bracket 200, so that the speaker 1 and the fixing assembly 2 are fixed together on the mounting bracket 200. Optionally, the locking member 3 can be configured as a nut to be threadedly connected to the connecting rod 21, and the locking member 3 can also be configured as other connection structures, and the locking member 3 and the connecting rod 21 are detachably connected, so that the connecting rod 21 can enter and exit the mounting hole 201 by removing the locking member 3, thereby disassembling and assembling the speaker 1.

[0051] The technical solution of the present invention is to set a fixing hole 1213 on the magnetic conductive member 121 of the speaker 1, set the expansion module 22 of the fixing assembly 2 in the fixing hole 1213 and abut the hole wall of the fixing hole 1213, so that the fixing assembly 2 provides circumferential support to the speaker 1, and the fixing assembly 2 and the speaker 1 are kept in a tight fit and locked with each other. When installing the speaker 1, the connecting rod 21 of the fixing assembly 2 is inserted into the mounting hole 201 of the mounting bracket 200, and the magnetic conductive member 121 and the locking member 3 of the fixing assembly 2 are respectively supported on both sides of the mounting bracket 200, so that the speaker 1 and the fixing assembly 2 can be locked in the axial direction of the speaker 1, and the fixing assembly 2 also limits the radial position of the speaker 1, so that the speaker 1 can be stably fixed. That is, the speaker module 100 adopted by the present invention uses the fixing hole 1213 on the magnetic conductive member 121 to achieve single-mounting point fixation, without occupying too much space, and can reduce the installation space of the speaker 1.

[0052] See also Figures 4 to 7 In one embodiment, the expansion module 22 includes a sleeve 221 and at least two supporting structures 222, the sleeve 221 is sleeved on the connecting rod 21; the at least two supporting structures 222 are arranged along the circumference of the sleeve 221 and are connected to the sleeve 221, and one end of the supporting structure 222 away from the sleeve 221 abuts against the wall of the fixing hole 1213, and the at least two supporting structures 222 can expand or contract radially outwardly along the fixing hole 1213 to adjust the abutment state between the supporting structure 222 and the wall of the fixing hole 1213.

[0053] In this embodiment, the expansion module 22 includes a sleeve 221 and at least two supporting structures 222. The sleeve 221 is sleeved on the connecting rod 21. The supporting structure 222 can move relative to the sleeve 221, so that the at least two supporting structures 222 can be closed or opened. Optionally, two supporting structures 222 can be arranged opposite to each other, or three, four or more supporting structures 222 can be arranged in a circumferential array, so that the force between the expansion module 22 and the speaker 1 is evenly distributed along the circumferential direction, thereby improving the installation stability of the speaker 1. The expansion module 22 is set as a collapsible and expandable structure, so that the expansion module 22 can cooperate with the fixing holes 1213 of different sizes, and the abutment state between the supporting structure 222 and the hole wall of the fixing hole 1213 can be adjusted by adjusting the opening degree of the supporting structure 222, for example, adjusting the force between the supporting structure 222 and the hole wall of the fixing hole 1213, or making the supporting structure 222 close to or away from the hole wall of the fixing hole 1213.

[0054] Optionally, the supporting structure 222 can be configured as an elastic arm connected to the sleeve 221, and the elastic arm can be bent and deformed outward to open outward. Part of the structure of the connecting rod 21 can be configured to gradually increase its cross-section in a direction away from the locking member 3, and the connecting rod 21 can be moved along its axial direction relative to the expansion module 22; when installing the speaker 1, the sleeve 221 is abutted against the mounting bracket 200, and the connecting rod 21 is moved toward the locking member 3. At this time, at least two supporting structures 222 of the expansion module 22 are gradually opened by the connecting rod 21, so that the supporting structure 222 is pressed against the wall of the fixing hole 1213.

[0055] The supporting structure 222 may also be configured as a combination structure of an expansion rod 2222 and a supporting member 2221 . The specific implementation manner may refer to the following embodiment and will not be described in detail herein.

[0056] See also Figures 5 to 7 In one embodiment, the supporting structure 222 includes a supporting member 2221 and an expansion rod 2222, the supporting member 2221 abuts against the hole wall of the fixing hole 1213, one end of the expansion rod 2222 is hinged to the sleeve 221, and the other end of the expansion rod 2222 is hinged to the supporting member 2221; the sleeve 221 and the speaker 1 can move relative to each other in the axial direction of the connecting rod 21 to adjust the inclination angle of the expansion rod 2222 relative to the connecting rod 21.

[0057] In this embodiment, the two ends of the expansion rod 2222 of the push structure are respectively hinged to the sleeve 221 and the support member 2221, so that the push structure can be opened or closed relative to the sleeve 221; when installing the speaker 1, the support member 2221 abuts against the hole wall of the fixing hole 1213, and static friction exists between the support member 2221 and the hole wall of the fixing hole 1213 to keep them relatively fixed, and by making the speaker 1 and the sleeve 221 relatively movable in the axial direction of the connecting rod 21, ... support member 2221 can be opened or closed relative to the sleeve 221; By changing the distance between the supporting member 2221 and the sleeve 221 in the axial direction of the connecting rod 21, the opening angle of the expansion rod 2222 relative to the sleeve 221 can be adjusted. Since the radial distance between the sleeve 221 and the supporting member 2221 in the fixing hole 1213 remains unchanged when the supporting member 2221 abuts against the hole wall of the fixing hole 1213, the tightening force between the supporting member 2221 and the hole wall of the fixing hole 1213 can be changed by changing the opening angle of the expansion rod 2222. Figure 2 and Figure 3 , Figure 2 is a schematic diagram of the speaker module 100 in a locked state, Figure 3 Schematic diagram of the speaker module 100 in a loose state. It can be seen that in the locked state, the outward expansion angle of the expansion rod 2222 is larger, and the force between the supporting member 2221 and the wall of the fixing hole 1213 is also larger.

[0058] Optionally, when installing the speaker 1, in a loose state, the sleeve 221 can be firstly abutted against the mounting bracket 200, so that there is a certain gap between the speaker 1 and the mounting bracket 200, and the mounting bracket 200 can be moved with the connecting rod 21 in the direction close to the mounting bracket 200. For example, in the following embodiment, a push structure 211 is provided on the connecting rod 21 to abut against the magnetic conductive member 121. In this embodiment, in the axial direction of the connecting rod 21, the end of the expansion rod 2222 connected to the sleeve 221 is closer to the mounting bracket 200 than the end of the expansion rod 2222 connected to the top holding member 2221; the top holding member 2221 abuts against the hole wall of the fixing hole 1213. When the connecting rod 21 drives the speaker 1 to move in the direction close to the mounting bracket 200, there is static friction between the top holding member 2221 and the hole wall of the fixing hole 1213, and the top holding member 2221 is kept relatively fixed, and the top holding member 2221 moves with the speaker 1 to the mounting bracket 200. When the connecting rod 21 drives the speaker 1 to move until the magnetic member 121 abuts against the mounting bracket 200, the locking member 3 is locked and abuts against the mounting bracket 200, so that the speaker 1 is in a locked state.

[0059] Combined with reference Figure 2 and Figure 3 In some embodiments, when the speaker 1 is installed in a loose state, the magnetic conductive member 121 of the speaker 1 can also be firstly made to abut against the mounting bracket 200, the supporting member 2221 can abut against the hole wall of the fixing hole 1213, and a gap can be left between the sleeve 221 and the mounting bracket 200. In this embodiment, in the axial direction of the connecting rod 21, the end of the expansion rod 2222 connected to the supporting member 2221 is closer to the locking member 3 than the end of the expansion rod 2222 connected to the sleeve 221; then the connecting rod 21 drives the sleeve 221 to move toward the locking member 3, and since the supporting member 2221 and the hole wall of the fixing hole 1213 are kept fixed due to static friction, the expansion rod 2222 will be opened outward relative to the sleeve 221, thereby increasing the tightening force between the supporting member 2221 and the hole wall of the fixing hole 1213, thereby improving the connection strength between the fixing component 2 and the speaker 1, so as to improve the stability of the fixed speaker 1. When the connecting rod 21 drives the sleeve 221 to move to a preset locking position, for example, when the sleeve 221 is moved to abut against the mounting bracket 200, the locking member 3 is locked to abut against the mounting bracket 200, so that the speaker 1 is in a locked state.

[0060] See also Figure 5In one embodiment, the sleeve 221 is threadedly connected to the connecting rod 21. In this arrangement, the connection strength between the sleeve 221 and the connecting rod 21 is relatively stable. In addition, as in the above embodiment, when the speaker 1 is installed, the sleeve 221 is firstly pressed against the mounting bracket 200, and the sleeve 221 and the connecting rod 21 can be relatively moved in the axial direction of the connecting rod 21 by rotating the connecting rod 21, so that the connecting rod 21 drives the speaker 1 to approach the mounting bracket 200, thereby expanding the rod 2222.

[0061] See also Figure 5 In one embodiment, the supporting structure 222 includes at least two expansion rods 2222 , and the at least two expansion rods 2222 are arranged along the axial direction of the fixing hole 1213 .

[0062] With this arrangement, the supporting member 2221 and the sleeve 221 both have a certain length along the axial direction of the connecting rod 21, and the supporting member 2221 and the sleeve 221 are connected by at least two expansion rods 2222. This can improve the connection stability between the supporting structure 222 and the sleeve 221. When locking the speaker 1, the supporting force exerted on the supporting member 2221 is also relatively uniform, so that the supporting member 2221 can stably press against the wall of the fixing hole 1213, thereby improving the overall structural stability.

[0063] See also Figure 1 In one embodiment, the locking member 3 is threadedly connected to the connecting rod 21 .

[0064] In this embodiment, the locking member 3 is configured as a nut, and the connecting rod 21 is provided with an external thread at least in the area cooperating with the locking member 3; such a configuration can not only keep the locking member 3 and the connecting rod 21 stably connected and convenient for assembly and disassembly; in addition, it is also convenient to adjust the position of the locking member 3 in the axial direction of the connecting rod 21, and ensure that the locking member 3 and the magnetic conductive member 121 of the speaker 1 are respectively pressed against the two sides of the mounting bracket 200. In addition, as in the aforementioned embodiment, in a loose state, the speaker 1 and the sleeve 221 can be moved relative to each other on the axis of the connecting rod 21 by moving the connecting rod 21 to adjust the opening angle of the expansion rod 2222. At this time, the connecting rod 21 can be driven to move along its axial direction by rotating the locking member 3, which is convenient for controlling the movement of the connecting rod 21 and is conducive to accurately controlling the moving distance of the connecting rod 21.

[0065] See also Figure 2 In one embodiment, a push structure 211 is provided at one end of the connecting rod 21 away from the locking member 3 , and the push structure 211 is supported on one end of the magnetic conductive member 121 away from the locking member 3 .

[0066] In this embodiment, the pushing structure 211 at the end of the connecting rod 21 abuts against the end of the magnetic component 121 away from the mounting bracket 200, and the magnetic component 121 also abuts against the mounting bracket 200, which is equivalent to clamping the magnetic component 121 between the pushing structure 211 and the mounting bracket 200 in the axial direction of the connecting rod 21. The speaker 1 can be limited in the axial direction of the connecting rod 21, thereby improving the installation stability of the speaker 1.

[0067] In some embodiments, the pushing structure of the expansion module 22 includes an expansion rod 2222 and a supporting member 2221. When installing the speaker 1, the speaker 1 and the sleeve 221 are moved relative to each other on the axis of the connecting rod 21 by moving the connecting rod 21 to adjust the opening angle of the expansion rod 2222, thereby adjusting the interaction force between the supporting member 2221 and the wall of the fixing hole 1213. At this time, when installing the speaker 1, the magnetic component 121 of the speaker 1 can be firstly abutted against the mounting bracket 200, leaving a certain gap between the pushing structure 211 and the magnetic component 121, and then the connecting rod 21 drives the sleeve 221 to move to one side of the mounting bracket 200 to open the expansion rod 2222 to increase the tightening force between the top holding member 2221 and the wall of the fixing hole 1213, until the pushing structure 211 abuts against the magnetic component 121 to limit the expansion angle of the expansion rod 2222, thereby avoiding excessive tightening force between the top holding member 2221 and the wall of the fixing hole 1213, which may cause the magnetic component 121 to be easily damaged. Alternatively, the sleeve 221 can be first abutted against the mounting bracket 200, leaving a moving gap between the magnetic component 121 and the mounting bracket 200, and the pushing structure 211 abuts against the magnetic component 121. When the connecting rod 21 is moved toward the mounting bracket 200, the pushing structure 211 pushes the magnetic component 121 to make the speaker 1 close to the mounting bracket 200, thereby opening the expansion rod 2222 to increase the tightening force between the top holding component 2221 and the wall of the fixing hole 1213, until the magnetic component 121 abuts against the mounting bracket 200 to limit the expansion angle of the expansion rod 2222, thereby preventing the tightening force between the top holding component 2221 and the wall of the fixing hole 1213 from being too large, which may cause the magnetic component 121 to be easily damaged.

[0068] See also Figure 6 In one embodiment, the push structure 211 is provided with a hollow area 212 connected to the fixing hole 1213; in this arrangement, the push structure 211 will not completely close the magnetic conductive member 121 to ensure air permeability, which is used for pressure relief and the sound quality of the speaker 1. Optionally, a through hole may be provided on the push structure 211 as the hollow area 212, or the push structure 211 may be provided in a structure similar to a "cross", a "M" or other structures as shown in the illustrated embodiment, which is not limited here.

[0069] See also Figure 5In one embodiment, a countersunk hole 1214 coaxial with the fixing hole 1213 is provided at one end of the magnetic conductive member 121 away from the locking member 3 , and the push structure 211 is located in the countersunk hole 1214 and abuts against the bottom wall of the countersunk hole 1214 .

[0070] This arrangement can utilize the countersunk hole 1214 to limit the push structure 211 in the radial direction of the fixing hole 1213, thereby limiting the fixing component 2, avoiding eccentricity and misalignment between the fixing component 2 and the fixing hole 1213 when the expansion module 22 is not opened and abuts against the wall of the fixing hole 1213, thereby avoiding the speaker 1 from being installed in place incorrectly, and avoiding the different expansion angles of the supporting structure 222 in different directions of the expansion module 22, resulting in inconsistent supporting forces applied to the wall of the fixing hole 1213, thereby ensuring that the speaker 1 is stably installed and the installation position is accurate.

[0071] See also Figure 6 In one embodiment, the abutting surface of the expansion module 22 against the hole wall of the fixing hole 1213 is a rough surface. The abutting surface of the expansion module 22 may be provided with structures such as saw teeth, particles or raised patterns, or the roughness of the abutting surface may be set higher, or materials such as rubber and leather may be provided to abut against the hole wall of the fixing hole 1213. This provides a higher static friction force between the expansion module 22 and the hole wall of the fixing hole 1213, so that the expansion module 22 is not easy to slide on the hole wall of the fixing hole 1213, thereby improving the stability of installing the speaker 1.

[0072] See also Figures 1 to 3 The present invention further proposes an electronic device, including a mounting bracket 200 and a speaker module 100. The electronic device may be, but is not limited to, a car, a speaker box, a mobile phone, a television, a VR device (Virtual Reality), an AR device (Augmented Reality), and an MR device (Mixed Reality). The specific structure of the speaker module 100 refers to the above embodiment. The mounting bracket 200 is provided with a mounting hole 201, and the connecting rod 21 of the speaker module 100 is passed through the mounting hole 201. The locking member 3 and the magnetic conductive member 121 of the speaker 1 are respectively in contact with the two side surfaces of the mounting bracket 200 that are arranged opposite to each other.

[0073] Since the electronic device proposed by the present invention adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0074] See also Figure 1 and Figure 2In one embodiment, the mounting bracket 200 is provided with a mounting boss 202 on the side facing the speaker 1 , and a groove 203 is formed on the side of the mounting boss 202 facing away from the speaker 1 , the magnetic conductive member 121 abuts against the top surface of the mounting boss 202 , and the locking member 3 is located in the groove 203 .

[0075] In this embodiment, the mounting bracket 200 can be set as a sheet metal part, and the mounting boss 202 and the groove 203 are simultaneously formed by stamping. The mounting bracket 200 can also form the mounting boss 202 and the groove 203 by injection molding or knife cutting. The locking member 3 and the part of the connecting rod 21 located on one side of the groove 203 are accommodated in the groove 203 to prevent the locking member 3 and the connecting rod 21 from protruding out of the mounting bracket 200, thereby reducing the risk of interference between the locking member 3 and the connecting rod 21 and other devices, making the overall structure neat and tidy, and facilitating the space left for arranging other devices and cooperating the electronic device with other modules.

[0076] See also Figure 2 In one embodiment, the sleeve 221 abuts against the mounting bracket 200. This arrangement allows the sleeve 221 and the locking member 3 to clamp the mounting bracket 200, so that the fixing assembly 2 itself can maintain a stable connection with the mounting bracket 200, thereby improving the connection strength and stability.

[0077] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
