Description

Technical Field

[0001] This utility model relates to a sound-generating device, specifically a novel waterproof sound-generating device. Background Technology

[0002] A sound-generating device is a device or apparatus capable of producing sound. Sound-generating devices convert energy into sound waves in various ways to transmit information or provide entertainment and comfort. Sound-generating devices are not limited to common loudspeakers and audio equipment, but also include various tools and machines capable of producing sound.

[0003] Existing sound-generating devices are designed with internal components such as magnets, washer, solder pads, and voice coils. These components need to be assembled in different locations. In order to reduce costs and assembly difficulty, the internal space is usually not waterproofed. This makes these internal components easily damaged when exposed to water. Utility Model Content

[0004] The purpose of this invention is to provide a novel waterproof sound-generating device that can ensure that the magnets, washer, voice coils, and other structures located in the area between the support and the diaphragm are isolated from the outside world, thereby achieving a good waterproof effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel waterproof sound-generating device includes a bracket and a U-cup and a front cover disposed above the bracket. The U-cup is fixed to the bottom of the bracket. The bracket and the U-cup together form a cavity structure with an opening at the top and a hollow interior. A magnet, a washer, and a voice coil are arranged sequentially from bottom to top inside the cavity formed by the bracket and the U-cup. A diaphragm is disposed between the front cover and the voice coil. The diaphragm is located below the solder pad and is attached to the lower end face of the solder pad. The diaphragm is combined with the bracket and waterproofs the area between the two.

[0006] Preferably, the magnet is mounted on the upper surface of the U-cup, and the washer is mounted on the upper surface of the magnet.

[0007] Preferably, a welding plate is also installed on the bracket, and the welding plate is located on the outside of the magnet and the washer.

[0008] Preferably, the bracket includes a main body and a support edge fixed to the upper surface of the main body, and an inner liner is fixed to the inner side of the support edge.

[0009] Preferably, a matching groove is formed between the support edge and the inner liner, the height of the inner liner is less than the height of the support edge, and the bottom of the welding sheet is engaged in the matching groove so that the welding sheet can be fixed on the bracket. By fixing the welding sheet on the bracket, the structure of the diaphragm is fixed on the inner side of the bracket.

[0010] Preferably, the membrane includes a membrane edge and an outer membrane body fixed below the membrane edge, and an inner membrane body is disposed inside the outer membrane body.

[0011] Preferably, a recessed groove is formed between the outer membrane body and the inner membrane body, the height of the outer membrane body is equal to the height of the inner membrane body, the recessed groove is a concave design, and the inner membrane body can be pressed into the space inside the inner liner. At this time, the outer membrane body is pressed on the upper end face of the inner liner body, the recessed groove is recessed in the space inside the inner liner body, and the space between the support and the membrane is sealed.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention utilizes a diaphragm placed between a support and a front cover. The outer membrane of the diaphragm is pressed onto the inner liner, and the inner membrane and the recessed groove are pressed into the inner space of the inner liner. The front cover is then combined with the support, fixing the diaphragm in place. This ensures that the support and the diaphragm are relatively stationary and do not wobble. Consequently, the magnets, washer, voice coils, and other structures located in the area between the support and the diaphragm are isolated from the outside environment, thus achieving a good waterproof effect.

[0025] Please see Figures 1 to 2 The present invention provides an embodiment of a novel waterproof sound-generating device, comprising a bracket 1, a U-cup 2 and a front cover 3 disposed above the bracket 1. The bracket 1 and the U-cup 2 together form a cavity structure with an opening at the top and a hollow interior. A magnet 4, a washer 5 and a voice coil 7 are arranged sequentially from bottom to top within the cavity formed by the bracket 1 and the U-cup 2. A diaphragm 8 is disposed between the front cover 3 and the voice coil 7. The diaphragm 8 is located below the welding piece 6 and is attached to the lower end face of the welding piece 6. The diaphragm 8 is combined with the bracket 1 and waterproofs the area between the two.

[0026] Please see Figure 3 The front cover 3 is positioned above the bracket 1 and is fixed together with the bracket 1.

[0027] Please see Figure 4 The U-cup 2 is fixed to the bottom of the bracket 1.

[0028] Please see Figure 5 Magnet 4 is installed on the upper surface of U-cup 2, washer 5 is installed on the upper surface of magnet 4, and welding piece 6 is also installed on bracket 1, which is located on the outside of magnet 4 and washer 5.

[0029] Please see Figure 6 The bracket 1 includes a main body 11 and a support edge 12 fixed to the upper surface of the main body 11. An inner liner 13 is fixed inside the support edge 12. A matching groove 14 is formed between the support edge 12 and the inner liner 13. The height of the inner liner 13 is less than the height of the support edge 12. The bottom of the welding piece 6 is engaged in the matching groove 14, so that the welding piece 6 can be fixed to the bracket 1. By fixing the welding piece 6 to the bracket 1, the structure of the membrane 8 is fixed inside the bracket 1, thereby enabling the bracket 1 to work with the membrane 8 to achieve a waterproof effect.

[0030] Please see Figure 7 The diaphragm 8 includes a membrane edge 81 and an outer membrane body 82 fixed below the membrane edge 81. An inner membrane body 83 is provided inside the outer membrane body 82. A recessed groove 84 is formed between the outer membrane body 82 and the inner membrane body 83. The height of the outer membrane body 82 is equal to the height of the inner membrane body 83. The recessed groove 84 is a concave design. Both the inner membrane body 83 and the recessed groove 84 can be pressed into the space inside the inner liner 13. At this time, the outer membrane body 82 is pressed on the upper end face of the inner liner 13. The recessed groove 84 is recessed in the space inside the inner liner 13 and seals the space between the support 1 and the diaphragm 8, so that the magnet 4, washer 5, solder sheet 6 and voice coil 7 located between the support 1 and the diaphragm 8 can achieve a waterproof effect.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
