[0032] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the invention and to fully convey the scope of the invention to those skilled in the art.

[0033] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0034] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0035] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0036] To address the issues of slow speaker driver installation and unstable fixation, this invention proposes an alternative speaker driver installation structure and a terminal device incorporating this structure. According to the speaker driver installation structure of this invention, the connection and disassembly between the mounting bracket and the speaker driver can be achieved quickly and efficiently, thereby improving the efficiency of speaker driver assembly and disassembly, and ensuring a reliable connection that is less prone to loosening. Furthermore, without changing the size of the speaker driver, it can be adapted to different terminal devices simply by altering the external dimensions or structure of the bracket, enhancing the versatility of the speaker driver.

[0037] Combination Figures 1 to 7 As shown, in some embodiments of the present invention, the speaker unit mounting structure 1 includes a speaker unit 10 and a mounting bracket 20. The speaker unit 10 includes at least a frame 11, and the outer peripheral surface of the frame 11 is provided with at least one insertion groove 111, at least a portion of the insertion groove 11 being arranged along the circumferential direction of the frame 11. The mounting bracket 20 is sleeved on the outside of the frame 11, and the inner wall surface of the mounting bracket 20 is provided with at least one insertion portion 21, which is inserted into the insertion groove 111 and engaged with the insertion groove 111.

[0038] Specifically, the loudspeaker unit 10 includes a frame 11, a magnetic circuit assembly (not shown in the figure) disposed inside the frame 11, and a diaphragm assembly (not shown in the figure) disposed at the opening of the frame. The diaphragm assembly has a voice coil at one end facing the magnetic circuit assembly. The voice coil is inserted into the magnetic gap of the magnetic circuit assembly. Thus, when the magnetic circuit assembly is energized, the voice coil can reciprocate along the axial direction under the action of the magnetic field of the magnetic circuit assembly, thereby driving the diaphragm assembly to reciprocate along the axial direction, thereby realizing vibration and sound generation.

[0039] The outer peripheral surface of the frame 11 may include multiple insertion slots 111, which are arranged around the outer peripheral surface of the frame 11. Partial structures of any insertion slot 111 are arranged along the circumferential direction of the frame 11. The mounting bracket 20 has an approximately annular structure, and its inner wall surface has at least one insertion portion 21. When it is necessary to connect the mounting bracket 20 to the speaker unit 10, the mounting bracket 20 is fitted onto the outside of the frame 11, and the insertion portion 21 on the mounting bracket 20 is inserted into the insertion slot 111. The mounting bracket 20 is then rotated along the circumferential direction of the frame 11, thereby fixing the insertion portion 21 within the insertion slot 111 and engaging it with the slot 111, thus connecting the mounting bracket 20 to the speaker unit 10. Simultaneously, the outer peripheral surface of the mounting bracket 20 also has at least one mounting portion 22, which has a through hole. Bolts or other connecting parts can pass through the through hole in the mounting portion 22 to fix the mounting bracket 20 to the terminal equipment.

[0040] According to the speaker unit mounting structure 1 of the present invention, by sleeved the mounting bracket 20 on the outside of the frame 11, the plug-in part 21 is inserted into the plug-in groove 111 and engaged with the plug-in groove 111. Compared with bolted connections or other connection methods, this reduces the number of connecting parts and lowers the complexity of speaker unit 10 installation. This allows for quick and efficient connection and disassembly between the mounting bracket 20 and the speaker unit 10, thereby improving the efficiency of speaker unit 10 assembly and disassembly. Furthermore, the connection is reliable and less prone to loosening. Simultaneously, without changing the size of the speaker unit 10, it can be matched to different terminal devices simply by changing the external dimensions or structure of the mounting bracket 20, enhancing the versatility of the speaker unit 10.

[0041] In some embodiments of the present invention, the number of insertion parts 21 and insertion slots 111 can each be multiple, and they are arranged in a one-to-one correspondence. The multiple insertion slots 111 can be arranged at equal intervals along the circumferential direction, thereby facilitating the insertion of the insertion parts 21 and the insertion slots 111. Alternatively, the multiple insertion slots 111 can be arranged at different angles along the circumferential direction, so that during the insertion process of the insertion parts 21 and the insertion slots 111, insertion can only be performed according to the corresponding positions, thus preventing incorrect installation.

[0042] Combined Figures 1 to 7 As shown, in some embodiments of the present invention, the plug-in portion 21 is engaged with the plug-in groove 111 along the axial direction of the speaker unit 10 and along the circumferential direction of the speaker unit 10, respectively.

[0043] The circumferential direction refers to the direction surrounding the axial direction of the speaker unit 10. By engaging the plug-in portion 21 and the plug-in slot 111 along the axial and circumferential directions of the speaker unit 10, the connection reliability between the speaker unit 10 and the mounting bracket 20 is further improved, preventing loosening between the speaker unit 10 and the mounting bracket 20.

[0044] Combined Figures 1 to 7 As shown, in some embodiments of the present invention, along the axial direction of the speaker unit 10, the bottom of the insertion groove 111 is provided with a first protrusion 112, the bottom of the insertion part 21 is provided with a second protrusion 211, and along the circumferential direction of the speaker unit 10, the insertion groove 111 is provided with a first sidewall 113 opposite to the first protrusion 112, and the second protrusion 211 is provided between the first sidewall 113 and the first protrusion 112 and is engaged with the first protrusion 112.

[0045] Specifically, the first protrusion 112 and the first sidewall 113 are spaced apart, forming a receiving space between them. The second protrusion 211 is disposed between the first protrusion 112 and the first sidewall 113, and is deformed by compression under the combined action of the first protrusion 112 and the first sidewall 113, thereby achieving the engagement of the plug-in portion 21 and the plug-in groove 111 along the circumferential direction of the speaker unit 10. At the same time, the top surface of the plug-in portion 21 abuts against the top surface of the plug-in groove 111, and the bottom surface of the second protrusion 211 abuts against the bottom surface of the plug-in groove 111, thereby achieving the engagement of the plug-in portion 21 and the plug-in groove 111 along the axial direction of the speaker unit 10.

[0046] Combined Figures 1 to 7 As shown, in some embodiments of the present invention, the first protrusion 112 is provided with a first support surface 114, the second protrusion 211 is provided with a second support surface 212, the first support surface 114 abuts against the second support surface 212, and the first support surface 114 and the second support surface 212 are intersecting.

[0047] Specifically, when the plug-in part 21 is engaged with the plug-in slot 111, the first support surface 114 and the second support surface 212 abut against each other and are intersecting, that is, the first support surface 114 and the second support surface 212 are not parallel, so that the first support surface 114 supports the second support surface 212 and the supporting force provided by the first support surface 114 is more concentrated on the second support surface 212.

[0048] Combined Figures 1 to 7 As shown, in some embodiments of the present invention, the first support surface 114 is arranged to intersect with the axial direction of the speaker unit 10.

[0049] Specifically, the first support surface 114 is set at an angle to the axial direction of the speaker unit 10, so that the supporting force provided by the first support surface 114 can act on the first support surface 114 simultaneously in the circumferential and axial directions of the speaker unit 10, thereby causing the plug-in part 21 and the plug-in groove 111 to engage in the axial and circumferential directions respectively.

[0050] Combined Figures 1 to 7 As shown, in some embodiments of the present invention, the insertion slot 111 is provided with an open end 115, the open end 115 and the first side wall 113 are arranged opposite to each other in the circumferential direction of the speaker unit 10, and the insertion part 21 is inserted into the interior of the insertion slot 111 through the open end 115.

[0051] Specifically, the axial opening size of the opening end 115 is larger than the axial opening size at any position within the insertion slot 111, thus facilitating the insertion part 21 to pass through. During the connection process between the mounting bracket 20 and the speaker unit 10, the mounting bracket 20 is first fitted onto the outside of the frame 11, with the insertion part 21 positioned opposite the opening end 115. Then, the mounting bracket 20 is rotated circumferentially along the frame 11, causing the insertion part 21 on the mounting bracket 20 to pass through the opening end 115 and extend into the insertion slot 111. The mounting bracket 20 is further rotated until the second protrusion 211 engages between the first side wall 113 and the first protrusion 112.

[0052] Combined Figures 1 to 7 As shown, in some embodiments of the present invention, in order to facilitate the insertion of the plug part 21 into the plug groove 111, the bottom surface of the plug part 21 is also provided with a guide surface 213. The guide surface 213 is provided as an inclined surface or an arc surface, thereby playing a guiding role in the insertion process of the plug part 21.

[0053] Combined Figures 1 to 7 As shown, in some embodiments of the present invention, along the axial direction of the speaker unit 10, the top end of the first support surface 114 is inclined toward the opening end 115, and the bottom end of the second support surface 212 abuts against the first support surface 114.

[0054] Specifically, the first support surface 114 is inclined toward the opening end 115, thereby facilitating the insertion of the second protrusion 211 between the first protrusion 112 and the first sidewall 113. Figure 4 , Figure 5 and Figure 7As shown, since the top of the first support surface 114 is inclined toward the opening end 115, and the bottom of the second support surface 212 abuts against the first support surface 114, the first support surface 114 provides a support force F for the second support surface 212. F is set at an angle to the axial direction and the circumferential direction of the speaker unit 10, so F can simultaneously provide a component force Fx along the circumferential direction of the speaker unit 10 and a component force Fy along the axial direction of the speaker unit 10, thereby simultaneously supporting the plug-in part 21 along the circumferential direction and the axial direction of the speaker unit 10, and realizing the snap-fit ​​of the plug-in part 21.

[0055] The acute angle between the first support surface 114 and the axial direction of the speaker unit 10 is α, and α < atanμ, where atan represents the arctangent function and μ represents the coefficient of friction between the first support surface 114 and the second support surface 212. This angle setting achieves a self-locking effect. When the mounting bracket 20 is rotated in the direction opposite to the insertion direction, it prevents the second support surface 212 from separating from the first support surface 114.

[0056] Combined Figures 1 to 7 As shown, in some embodiments of the present invention, the plug-in portion 21 is provided with a first end portion 214 that abuts against the first sidewall 113. Along the circumferential direction of the speaker unit 10, the distance between the first end portion 214 and the bottommost end of the second support surface 212 is L1, the distance between the first sidewall 113 and the bottommost end of the first support surface 114 is L2, and the distance between the first sidewall 113 and the topmost end of the first support surface 114 is L3, wherein L2 is greater than L1 and less than L3.

[0057] The second support surface 212 is arranged along the axial direction of the speaker unit 10, and the first end 214 is also arranged along the axial direction of the speaker unit 10, meaning the second support surface 212 and the first end 214 are parallel. Along the circumferential direction of the speaker unit 10, the distance between any position on the first end 214 and the second support surface 212 is equal. Since L2 is less than L3, it is convenient to insert the second protrusion 211 between the first sidewall 113 and the first support surface 114. Simultaneously, since L2 is greater than L1, when the second protrusion 211 is inserted between the first sidewall 113 and the first support surface 114, the first support surface 114 and the second support surface 212 can abut and engage.

[0058] Combined Figures 1 to 7 As shown, in some embodiments of the present invention, the bottom of the insertion groove 111 is further provided with a third protrusion 116, the third protrusion 116 is provided between the first side wall 113 and the first protrusion 112, a receiving groove is provided between the first protrusion 112 and the third protrusion 116, and at least a portion of the second protrusion 211 is provided in the receiving groove and abuts against the first protrusion 112.

[0059] By providing a third protrusion 116 and forming a receiving groove between it and the first protrusion 112, when the second protrusion 211 is inserted between the first sidewall 113 and the first protrusion 112, at least a portion of the second protrusion 211 can be placed in the receiving groove. The first protrusion 112 and the third protrusion 116 together clamp the second protrusion 211, further improving the fixing effect of the second protrusion 211 and ensuring the reliability of the connection between the insertion part 21 and the insertion groove 111.

[0060] Another aspect of the present invention provides a terminal device having the speaker unit mounting structure described in any of the above claims.

[0061] Combined Figure 1 Figure 7 As shown, a second aspect of the present invention provides a terminal device having a speaker unit mounting structure 1 as described above. The terminal device can be a speaker, headphones, a car, or other device that emits sound through a speaker unit. The speaker unit mounting structure 1 is connected to the housing or other structure of the terminal device via a mounting bracket 20, thereby fixing the speaker unit 10 to the terminal device. The mounting bracket 20 can be integrated with the speaker unit 10 and installed together on the terminal device; alternatively, the mounting bracket 20 can be connected to the terminal device first, and then the speaker unit 10 can be inserted into the mounting bracket 20 to achieve the installation of the speaker unit 10.

[0062] Since the terminal device in this application has the same technical features as the speaker unit mounting structure 1 in any of the above embodiments, and can achieve the same technical effect, it will not be described again here.

[0063] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
