[0066] Figure 2 and Figure 3 Schematic diagram of the exploded view of the loudspeaker assembly of this embodiment.

[0067] In some embodiments, as Figure 1-Figure 3 As shown, the speaker assembly in this embodiment includes a speaker 1, a connecting portion 2, and a protective structure 3. The protective structure 3 includes a first shell portion 31, a second shell portion 32, and a fixed hook 33, and the fixed hook 33 is provided on the first shell portion 31 and / or the second shell portion 32. The protective structure 3 is used to protect the speaker 1, and the speaker 1 can be electrically connected to components outside the protective structure 3 using the connecting portion 2. For example, the circuit board in a mobile phone or laptop computer. At the same time, the first shell portion 31 is provided with a speaker groove 311 for mounting the speaker 1.

[0068] Figure 4 Schematic diagram of the explosion of the shell member and the loudspeaker 1 of this embodiment. Figure 5 2 is a schematic cross-sectional view of the shell member of this embodiment. Figure 6 3 is a schematic structural diagram of the first shell 31 and the loudspeaker 1 of this embodiment.

[0069] In some embodiments, as Figure 4-Figure 6 As shown, the housing member in this embodiment includes a second housing portion 32 and a connecting portion 2 disposed on the second housing portion 32. The second housing portion 32 is configured as an injection molded part, with the connecting portion 2 being an insert, such that a portion of the conductive member 21 is disposed inside the second housing portion 32. The speaker 1 includes two contacts 11 for abutting against two first electrical contact areas 211.

[0070] Figure 7 2 is a schematic structural diagram of the connecting portion 2 of this embodiment. The connecting portion 2 of this embodiment includes two conductive members 21. The conductive members 21 have a first electrical contact region 211 and a second electrical contact region 212.

[0071] When the first shell 31 is detachably connected to the second shell 32 through the fixed hook 33, the connecting part 2 is configured to abut the two contacts 11 of the speaker 1 against the two first electrical contact areas 211 respectively to achieve electrical contact, and the two second electrical contact areas 212 are exposed to the outside of the protective structure 3.

[0072] Specifically, the first electrical contact area 211 and the second electrical contact area 212 in this embodiment are exposed on the surface of the second shell 32, so that after the second shell 32 and the first shell 31 are assembled, the speaker 1 is easily electrically connected to external components through the shell structure.

[0073] In summary, the speaker assembly of this embodiment is provided with a speaker groove 311 for accommodating the speaker 1 in the first shell 31, and the speaker 1 is electrically connected by the connecting portion 2. Thus, the second shell 32 is configured as an injection molded part, and the connecting portion 2 is fixed to the second shell 32 as an insert to form a shell member with electrical properties. The connection structure of the speaker assembly is simplified. When the first shell 31 and the shell member are connected by the fixed hook 33, the contact 11 can directly achieve electrical contact with the corresponding first electrical contact area 211, while the second electrical contact area 212 is exposed to the outside of the protective structure 3, so that external components can power or control the speaker assembly. On the other hand, by driving the fixed hook 33 away from the first shell 31 or the second shell 32, the first shell 31, the shell member and the speaker 1 can be separated from each other, which is helpful for the maintenance and classified recycling of each part. In particular, during multiple disassembly processes, efficiency can be improved and damage to components can be avoided.

[0074] In some embodiments, as Figure 7 As shown, two conductive members 21 are spaced apart. The conductive member 21 further includes a first connection end 22, a second connection end 23, and an extension 24 positioned between the first connection end 22 and the second connection end 23. The extension 24 is embedded within the second shell portion 32. A first electrical contact region 211 and a second electrical contact region 212 are formed at the first connection end 22 and the second connection end 23, respectively.

[0075] In this embodiment, the extension body 24 is used to extend the distance between the first connection end 22 and the second connection end 23, so that the connection position between the external component and the speaker 1 can be extended to the outside of the protective structure 3. This simplifies the connection method between the external component and the speaker 1.

[0076] In some embodiments, as Figure 1-Figure 3 As shown, the first shell portion 31 has an avoidance groove 312 , and the avoidance groove 312 is recessed from the side surface of the first shell portion 31 toward the speaker groove 311 .

[0077] The second shell 32 includes a second plate 321, and the two second connection ends 23 are spaced apart along the edge of the second plate 321. The first electrical contact area 211 and the second electrical contact area 212 face the same side of the protective structure 3 through the avoidance groove 312.

[0078] In this embodiment, the avoidance groove 312 extends through the first shell 31 in the thickness direction of the second plate 321. When the first shell 31 and the second plate 321 are assembled together, at least a portion of the second electrical contact area 212 is located inside the avoidance groove 312 in a direction perpendicular to the second plate 321. This facilitates the use of connecting devices such as spring pins to supply power to the speaker 1.

[0079] In some embodiments, as Figure 2-Figure 4 As shown, the speaker assembly also includes a gasket 41. The second shell 32 also includes a positioning body 322 and two bosses 323 corresponding to the two first connection ends 22. The two bosses 323 and the positioning body 322 are protruding from the surface of the second plate 321 near the first shell 31, and the first electrical contact area 211 is exposed on the surface of the bosses 323. When the protective structure 3 is in the assembled state, the positioning body 322 abuts against the speaker 1 through the gasket 41.

[0080] Optionally, there are two positioning bodies 322, which are spaced apart along the length direction of the loudspeaker 1. The positioning bodies 322 are cross-shaped raised structures.

[0081] The positioning body 322 in this embodiment is used to position the speaker 1 after the first shell 31 and the second plate 321 are fastened together, ensuring that the speaker 1 is stably positioned within the speaker slot 311 and preventing it from shaking. Furthermore, a gasket 41 is placed between the two to reduce the transmission of vibrations from the speaker 1 to external components during operation. Furthermore, the gasket 41 prevents the positioning body 322 from crushing the speaker 1.

[0082] In some embodiments, as Figure 4 As shown, the speaker 1 further includes two springs 12. The two springs 12 bend toward the second shell 32 and form two contacts 11. The contacts 11 are in contact with the first electrical contact area 211, and the springs 12 are elastically deformed away from the second shell 32.

[0083] Specifically, when the speaker 1 is placed in the speaker slot 311, the two springs 12 are located above the speaker slot 311. As the first shell 31 approaches the second shell 32, the two first electrical contact areas 211 push against the two contacts 11, forcing the springs 12 to elastically deform. This ensures the stability of the connection between the contacts 11 and the first electrical contact areas 211.

[0084] In some embodiments, as Figure 2 and Figure 3 As shown, the first shell 31 includes a first plate 313 and a blocking body 314. The first plate 313 is provided with a sound outlet 315. The blocking body 314 is protruded on the side of the first plate 313 close to the second shell 32. The blocking body 314 is arranged around the sound outlet 315 and forms a speaker groove 311 with the first plate 313.

[0085] The speaker 1 includes a diaphragm 14. When one side of the diaphragm 14 is disposed in the speaker groove 311, the diaphragm 14 can be exactly oriented toward the sound outlet 315. Thus, the enclosure 314 can effectively limit the position of the speaker 1, ensuring that the diaphragm 14 is aligned with the sound outlet 315.

[0086] In some embodiments, as Figure 3 As shown, the speaker assembly further includes a first sealing ring 42 . The first sealing ring 42 surrounds the sound outlet 315 . The speaker 1 is clamped in the speaker groove 311 and abuts against the first plate 313 through the first sealing ring 42 .

[0087] In this embodiment, the first sealing ring 42 provides a seal, allowing sound waves generated by the diaphragm 14 to propagate from the sound outlet 315 toward the outside of the speaker assembly, preventing the sound waves from propagating through the gap between the speaker 1 and the first plate 313 and into the interior of the protective structure 3. Furthermore, the provision of the gasket 41 and the first sealing ring 42 on either side of the speaker 1 prevents the speaker 1 from being crushed by the first plate 313 and the positioning body 322. Furthermore, impurities such as dust and liquids are prevented from entering the interior of the protective structure 3 through the sound outlet 315.

[0088] In some other embodiments, the speaker assembly further includes double-sided tape. The double-sided tape is disposed around the sound outlet 315, with one side of the tape adhered to the first plate 313 and the other side adhered to the speaker 1. The double-sided tape in this embodiment also serves to secure the speaker 1 and seal the gap between the speaker 1 and the first plate 313.

[0089] In some embodiments, as Figure 3 As shown, the first shell 31 further includes a plurality of positioning hooks 5, which are arranged on a side of the enclosure 314 away from the first plate 313, and the plurality of positioning hooks 5 are bent toward the speaker slot 311. Figure 6 As shown, the speaker 1 is locked in the speaker slot 311 through a plurality of positioning hooks 5 .

[0090] In this embodiment, before the first shell 31 and the second shell 32 are assembled, the speaker 1 can be fixed in the speaker groove 311 by the positioning hook 5 to prevent the speaker 1 from being separated from the first shell 31 during the assembly process of the second shell 32 and the first shell 31.

[0091] In some embodiments, as Figure 3 As shown, the loudspeaker 1 further includes a body 13 , a diaphragm 14 is disposed on the body 13 , and the body 13 has a mating surface 131 .

[0092] Further reference Figure 4 As shown, the plurality of positioning hooks 5 include a first hook 51 and a second hook 52. The bending direction of the first hook 51 is opposite to the bending direction of the second hook 52. The positioning hook 5 has a guide slope 53 and a clamping surface 54. The clamping surface 54 is located between the guide slope 53 and the first plate 313. Preferably, the first hook 51 and the second hook 52 in this embodiment are provided in pairs.

[0093] As the speaker 1 is pressed downward from the top of the speaker slot 311 toward the sound outlet 315, the speaker 1 drives the first hook 51 and the second hook 52 away from each other via the guide slope 53. When the speaker 1 moves into the speaker slot 311, the engaging surface 54 engages with the mating surface 131. This simplifies the assembly of the speaker 1 with the first housing 31 and prevents the speaker 1 from being scratched by the positioning hook 5 during the process. Furthermore, the operator can more easily remove the speaker 1 from the speaker slot 311 when disassembling the speaker assembly.

[0094] In some embodiments, as Figure 3 and Figure 6 As shown, the first shell 31 includes a first plate 313 and a connecting retaining wall 316 protruding from the edge of the first plate 313. The first plate 313 defines a sound outlet 315. The connecting retaining wall 316 is disposed around the sound outlet 315, and a portion of the connecting retaining wall 316 bends toward the sound outlet 315 to form an avoidance groove 312.

[0095] The second shell portion 32 is connected to the first shell portion 31 via a connecting retaining wall 316. The second shell portion 32 and the first shell portion 31 form a receiving cavity, and the speaker slot 311 is located within the receiving cavity. The receiving cavity in this embodiment can also be used to accommodate multiple speakers 1. In other words, multiple speakers 1 can be installed simultaneously in the protective structure 3, making the internal structure of the speaker assembly more compact.

[0096] In some embodiments, as Figure 2 and Figure 4 As shown, the second plate 321 defines a plurality of deformation slots 325 corresponding to the plurality of fixing hooks 33 , and the deformation slots 325 are disposed adjacent to the fixing hooks 33 .

[0097] The plurality of fixed hooks 33 are disposed on the edge of the second plate 321 and are bent in a direction away from the edge of the second plate 321 . The plurality of fixed hooks 33 include a third hook 331 and a fourth hook 332 . The third hook 331 and the fourth hook 332 are bent in opposite directions.

[0098] Specifically, the deformation groove 325 passes through the second plate 321 and has a connecting side wall, which is also used to form a portion of the plate edge of the second plate 321. The fixing hook 33 is protruded from the connecting side wall and is located above the deformation groove 325.

[0099] When the first shell 31 and the second shell 32 are engaged with each other, the third hook 331 and the fourth hook 332 move away from each other, causing the deformation groove 325 to deform, that is, causing the sidewall of the deformation groove 325 to bend inwardly of the deformation groove 325. This reduces the pressure exerted by the fixing hook 33 on the first shell 31, prevents scratches on the first shell 31, and makes the connection between the first shell 31 and the second shell 32 easier.

[0100] In some embodiments, as Figure 6 As shown, a portion of the connecting retaining wall 316 bends toward the speaker slot 311 to form a plurality of slots 61, through which the plurality of fixed hooks 33 engage with the first shell portion 31. In this embodiment, the width of the slots 61 is configured to be slightly larger than the width of the fixed hooks 33, thereby ensuring smoother engagement between the fixed hooks 33 and the slots 61.

[0101] In some embodiments, as Figure 4 and Figure 6 As shown, the speaker assembly also includes a second sealing ring 43, which is disposed on the connecting retaining wall 316. The fixing hook 33 and the deformation groove 325 are located on the outside of the second sealing ring 43. This ensures that the deformation of the second sealing ring 43 caused by the first shell 31 and the second shell 32 in various areas is consistent, thereby ensuring the sealing of the protective structure 3.

[0102] In some embodiments, as Figure 4-Figure 6 As shown, the second shell portion 32 also includes a positioning flange 324, which is protruding from the second plate 321. The connecting retaining wall 316 defines a sealing groove 3163, which extends toward the second shell portion 32. The sealing groove 3163 curves and extends in the area corresponding to the latching groove 61. In other words, a portion of the sealing groove 3163 curves along with the connecting retaining wall 316. When the protective structure 3 is in the assembled state, the positioning flange 324 extends into the sealing groove 3163 and abuts the second sealing ring 43.

[0103] The positioning flange 324 in this embodiment cooperates with the sealing groove 3163 to improve the positioning accuracy of the first shell 31 and the second shell 32 after assembly, preventing misalignment between the first shell 31 and the second plate 321. Furthermore, the positioning flange 324 extends into the sealing groove 3163 and compresses the second sealing ring 43 to deform, maintaining the sealing performance of the protective structure 3. Furthermore, the curved sealing groove 3163 increases its length, further enhancing the sealing effect.

[0104] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to fall within the scope of protection of the present invention.
