[0039] 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.
[0040] In one embodiment, refer to the appendix to the specification. Figures 1 to 6The present invention provides a speaker mounting structure comprising: a housing 1, a speaker 2, and a fixing plate 3. The housing 1 is provided with a mounting groove 11, and 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, and the waterproof strip 122 surrounds the outside of the sound outlet 121. The waterproof strip 122 is integrally formed with the housing 1. The speaker 2 is adapted to be installed in the mounting groove 11. The fixing plate 3 is provided at the opening of the mounting groove 11, and the speaker 2 is sandwiched between the housing 1 and the fixing plate 3. The fixing plate 3 is provided with a snap-fit member 31, and the corresponding position of the housing 1 is provided with a snap-fit part 17. When the snap-fit member 31 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.
[0041] 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 fixing piece 3 cooperates with the housing 1 to achieve tool-free snap-fit assembly of the speaker 2, compressing the waterproof strip 122 to form a seal while completing mechanical fixation. Assembly is simple and improves 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-on quick-release structure, eliminating the need for traditional screws / adhesives and other auxiliary fixing parts, greatly reducing structural redundancy space. It is especially suitable for ultra-thin electronic devices, achieving miniaturization and refinement of the terminal product while ensuring acoustic performance.
[0042] In one embodiment, refer to the appendix to the specification. Figures 1 to 6 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 not lower than the top of the mounting groove 11. By protruding the speaker 2 from the mounting groove 11, the speaker 2 compresses the waterproof strip 122, improving waterproof reliability.
[0043] 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.
[0044] In one embodiment, refer to the appendix to the specification. Figure 4 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.
[0045] 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.
[0046] Reference manual attached Figure 6 The fixing piece 3 includes a fixing piece body 32 and flanges 33 at both ends of the fixing piece body 32. Both flanges 33 extend towards the bottom of the mounting groove 11, and snap-fit pieces 31 are disposed on the flanges 33. The fixing piece body 32 also has recesses 322, which are used for weight reduction and local support of the speaker. These recesses 322 also serve as reinforcing ribs. The fixing piece 3 can be integrally bent from a steel sheet. Of course, the fixing piece 3 can also be made of other materials and processed in other ways, as long as the above functions can be achieved.
[0047] Furthermore, for scenarios where the speaker 2 needs to be disassembled, an auxiliary structure 21, such as a pull ring or hook, can be installed on the top of the speaker 2 to serve as a leverage point for hands or tools, making disassembly more convenient. A clearance structure 321 is provided at the corresponding position of the fixing plate 3 to prevent the fixing plate 3 from interfering with the auxiliary structure 21. The clearance structure 321 can be a groove, hole, or other structure, and can also serve as a weight-reduction structure. Of course, without affecting the structural stability of the fixing plate 3, additional weight-reduction holes can be provided to further reduce the overall weight of the device.
[0048] In this embodiment, by providing snap-fit parts 17 on two relatively short first sidewalls 13 and third sidewalls 15, the fixing plate body 32 is made as long as possible. When assembling and pressing the fixing plate 3, the fixing plate 3 is more easily plastically deformed, so that the snap-fit parts 31 on the fixing plate 3 are snapped together with the snap-fit parts 17 on the two sidewalls. This can effectively reduce the assembly operation force and improve the ease of operation.
[0049] 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.
[0050] In one embodiment, refer to the appendix to the specification. Figures 1 to 6 The snap-fit component 31 includes at least two protrusions, which are respectively disposed on the folded edges 33 at both ends of the fixing piece 3. 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.
[0051] Alternatively, the snap-fit member 31 includes at least two recesses, which are respectively disposed on the folded edges 33 at both ends of the fixing piece 3. The recesses can be arc-shaped grooves, blind holes, through holes, etc. The snap-fit part 17 includes at least two protrusions, which are respectively disposed on the first sidewall 13 and the third sidewall 15, so that the protrusions are adapted to connect with the corresponding recesses.
[0052] It should be noted that the specific structures of the snap-fit component 31 and the snap-fit part 17 are described with reference to the accompanying drawings. In actual use, the snap-fit component 31 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.
