[0037] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0038] In one embodiment, refer to the appendix to the specification. Figures 1 to 4The present invention provides a speaker mounting structure comprising: a housing 1 and a speaker 2. The housing 1 is provided with a mounting groove 11. The bottom of the mounting groove 11 is provided with a sound outlet 121 and a waterproof strip 122. The sound outlet 121 penetrates the bottom of the mounting groove 11. The waterproof strip 122 surrounds the outside of the sound outlet 121 and is integrally formed with the housing 1. The speaker 2 is adapted to be installed in the mounting groove 11. The speaker 2 is provided with a snap-fit ​​component 21. The housing 1 is provided with a snap-fit ​​part 17 at a corresponding position. When the snap-fit ​​component 21 and the snap-fit ​​part 17 are adapted to snap-fit, the speaker 2 squeezes the waterproof strip 122, so that the speaker 2 is sealed to the bottom of the mounting groove 11.

[0039] In this embodiment, by integrally molding the housing 1 and the waterproof strip 122, assembly errors are eliminated, ensuring uniform pressure around the sound outlet 121 and improving waterproof reliability. The snap-fit ​​part 21 and the snap-fit ​​part 17 cooperate to achieve tool-free assembly, compressing the waterproof strip 122 to form a seal while completing mechanical fixation, simplifying assembly and improving the first-pass yield of the production process. In addition, the speaker 2 is precisely embedded in the mounting groove 11 and is firmly fixed by a snap-fit ​​quick-release structure, eliminating the need for traditional screws / adhesives and other auxiliary fixing parts, greatly reducing structural redundancy space, which is especially suitable for ultra-thin electronic devices, achieving miniaturization and refinement of the terminal product while ensuring acoustic performance.

[0040] In one embodiment, refer to the appendix to the specification. Figures 1 to 4 The mounting groove 11 has a recess 123 at its bottom, and a sound outlet 121 is located in the center of the recess 123. The sound outlet 121 can be configured as several spaced-apart strip-shaped holes, or other shapes. A waterproof strip 122 surrounds the recess 123, and the waterproof strip 122 is spaced from the side wall of the mounting groove 11 by a preset distance. The distance must take into account the expansion coefficient of the waterproof strip 122 after compression to avoid interference with the side wall. When the speaker 2 is fitted into the mounting groove 11, the top of the speaker 2 is flush with the top of the mounting groove 11. The recessed mounting of the speaker 2 saves axial space, making it easier to achieve miniaturization and refinement of electronic equipment.

[0041] Furthermore, the waterproof strip 122 is a silicone strip, and the height of the silicone strip is greater than the gap between the bottom wall of the horn 2 and the bottom of the mounting groove 11. That is, when the horn 2 is fitted into the mounting groove 11, the horn 2 compresses the silicone strip, causing the silicone strip to be tightly connected to the horn after compression. The upper surface of the silicone strip and the bottom wall of the horn 2 form the main sealing surface, and the side wall of the silicone strip, due to compression and expansion, forms a secondary sealing surface with the side wall of the mounting groove 11, achieving excellent waterproof effect. The silicone strip and the housing 1 are integrally molded by two-color injection molding or insert injection molding, or other methods can be used to achieve integral molding. Of course, the waterproof strip 122 can also be set as other soft rubber structures, as long as the above functions can be achieved.

[0042] In one embodiment, refer to the appendix to the specification. Figure 3 The housing 1 includes a bottom wall 12 and a first side wall 13, a second side wall 14, a third side wall 15, and a fourth side wall 16 connected end to end in sequence. The first side wall 13, the second side wall 14, the third side wall 15, and the fourth side wall 16 are fixed to the same side of the bottom wall 12. The bottom wall 12, the first side wall 13, the second side wall 14, the third side wall 15, and the fourth side wall 16 form a mounting groove 11. A snap-fit ​​part 17 is provided in at least one of the first side wall 13, the second side wall 14, the third side wall 15, and the fourth side wall 16.

[0043] Furthermore, the first sidewall 13 and the third sidewall 15 are arranged in parallel, the second sidewall 14 and the fourth sidewall 16 are arranged in parallel, and the length of the first sidewall 13 is less than the length of the second sidewall 14; the snap-fit ​​part 17 is provided on the first sidewall 13 and the third sidewall 15.

[0044] The first sidewall 13 has two spaced first gaps 131, the top of which extends through the top of the first sidewall 13, and the bottom of which is a predetermined distance from the bottom wall 12. A snap-fit ​​part 17 is disposed between the two first gaps 131. The third sidewall 15 has two spaced second gaps 151, the top of which extends through the top of the third sidewall 15, and the bottom of which is a predetermined distance from the bottom wall 12. A snap-fit ​​part 17 is disposed between the two second gaps 151.

[0045] Furthermore, for scenarios where the speaker needs to be disassembled, auxiliary structures such as pull rings or hooks can be installed on the top of the speaker to serve as leverage points for hands or tools, making disassembly more convenient.

[0046] In this embodiment, by setting gaps at intervals on two oppositely arranged first sidewalls 13 and third sidewalls 15, and then setting the snap-fit ​​part 17 in the position between the gaps, the two side plates of the housing 1 are more easily plastically deformed when assembling and pressing the horn 2, so that the snap-fit ​​part 21 on the horn 2 is snapped to the snap-fit ​​part 17 on the two side walls, which can effectively reduce the assembly operation force and improve the ease of operation.

[0047] It should be noted that the above is a specific design of the structure of the shell 1 with the horn 2 as a cuboid structure. When the horn 2 is of other shapes, the specific structure of the shell 1 needs to be changed accordingly. Any structure that can achieve the above functions is acceptable. This is only for better illustrating the present utility model and should not constitute a limitation on the present utility model.

[0048] In one embodiment, refer to the appendix to the specification. Figures 1 to 4The snap-fit ​​component 21 includes at least two protrusions, which are respectively disposed at both ends of the speaker 2. The protrusions can be triangular bosses, trapezoidal bosses, arc-shaped bosses, etc. The snap-fit ​​portion 17 includes at least two recesses, which can be arc-shaped grooves, blind holes, through holes, etc. The at least two recesses are respectively disposed on the first sidewall 13 and the third sidewall 15, so that the recesses are adapted to connect with the corresponding protrusions. Of course, the protrusions can also be disposed around the speaker 2, and the recesses can be disposed at the corresponding positions on the sidewalls around the mounting groove 11.

[0049] Alternatively, the snap-fit ​​member 21 includes at least two recesses, each located at one end of the speaker 2. These recesses can be arc-shaped grooves, blind holes, through holes, etc. The snap-fit ​​member 17 includes at least two protrusions, each located on the first sidewall 13 and the third sidewall 15, allowing the protrusions to mate and connect with their corresponding recesses. Alternatively, the recesses can be located around the speaker 2, while the protrusions are located on the corresponding positions of the sidewalls surrounding the mounting groove 11.

[0050] It should be noted that the specific structures of the snap-fit ​​component 21 and the snap-fit ​​part 17 are described with reference to the accompanying drawings. In actual use, the snap-fit ​​component 21 and the snap-fit ​​part 17 can be set to other structures according to actual needs, as long as the above functions can be achieved. This is only for better illustrating the present utility model and should not constitute a limitation on the present utility model.
