[0046] In order to fully understand the purpose, features and effects of the present invention, the present invention is described in detail through the following specific embodiments and the accompanying drawings. The description is as follows:

[0047] Please refer to Figures 1 to 7 As shown in the figure, the utility model provides a waterproof speaker 1, which can be a long speaker and includes: a speaker seat component 11, a diaphragm component 12, a voice coil 13 and a magnetic return component 14.

[0048] The speaker seat assembly 11 includes a speaker seat 111 and an annular side magnetic conductive plate 112 . The speaker seat 111 is connected to the annular side magnetic conductive plate 112 . An annular groove 113 is disposed on the top of the speaker seat 111 . An annular inner retaining wall 114 is disposed on the inner periphery of the annular groove 113 .

[0049] The diaphragm assembly 12 includes an annular metal support 121 and a diaphragm 122. The diaphragm 122 is integrally injection molded on the annular metal support 121. The bottom of the annular metal support 121 is arranged in the annular groove 113. The inner edge of the bottom of the annular metal support 121 abuts against the annular inner retaining wall 114. The material of the annular metal support 121 can be stainless steel, and the material of the diaphragm 122 can be silicone. In addition, since a general speaker seat does not have a groove, too much glue will overflow to the outside of the speaker seat, and if too little glue is applied, insufficient bonding strength will result after assembly. Therefore, the annular groove 113 of the waterproof speaker 1 of the utility model can store glue, and as long as a certain amount of glue is applied to the annular groove 113, the bonding strength after assembly can be ensured.

[0050] The voice coil 13 is movably disposed inside the inner periphery of the annular side magnetic conductive plate 112 and connected to the bottom of the diaphragm 122 .

[0051] The magnetic return assembly 14 includes a magnetic base 141, two side conductive magnets 144 and a main magnetic unit 142. Each side conductive magnet 144 and the main magnetic unit 142 are arranged on the magnetic base 141. The main magnetic unit 142 may include a main magnetic plate 1421 and a main magnetic 1422. The main magnetic plate 1421 is arranged on the main magnetic 1422. A magnetic gap 143 is formed between each side conductive magnet 144 and the main magnetic unit 142. The speaker base assembly 11 is arranged on the magnetic return assembly 14, and the voice coil 13 is movably arranged in the magnetic gap 143.

[0052] When the waterproof speaker 1 is used, it can be combined with an electronic device (not shown). After the voice coil 13 receives the input external electronic signal, the electromagnetic action of the voice coil 13 cooperates with the magnetic return assembly 14 to drive the diaphragm 122 to operate through the magnetic force provided by the magnetic base 141, the side magnets 144, the main magnetic unit 142 and the annular side magnetic plate 112 of the magnetic return assembly 14, thereby causing the waterproof speaker 1 to output sound.

[0053] Since the bottom of the annular metal bracket 121 of the diaphragm assembly 12 is disposed in the annular groove 113, and the inner edge of the bottom of the annular metal bracket 121 abuts against the annular inner retaining wall 114, the waterproof speaker 1 of the present invention can limit the movement of the annular metal bracket 121 through the annular inner retaining wall 114. In this way, the waterproof speaker 1 of the present invention can effectively increase the structural strength of the waterproof speaker 1 by utilizing the cooperation between the speaker seat assembly 11 and the diaphragm assembly 12, thereby improving the water pressure resistance and achieving a better waterproof effect.

[0054] In addition, since the diaphragm assembly 12 of the waterproof speaker 1 is made by integrally injecting the diaphragm 122 into the annular metal bracket 121, and the material of the annular metal bracket 121 can be stainless steel, under the same strength, the thickness of a general plastic bracket (for example: PPA material) needs to be 0.36 mm, while the thickness of the annular metal bracket 121 only needs to be 0.15 mm, so that the strength of the annular metal bracket 121 is better and the thickness is thinner, thereby allowing the waterproof speaker 1 to be further narrowed.

[0055] In addition to the above embodiments, in one embodiment of the present invention, the outer periphery of the annular side magnetic conductive plate 112 may be provided with an annular chamfered groove 1121, and the speaker seat 111 may extend from the outside to the inside to connect to the annular chamfered groove 1121 to form the annular groove 113 and the annular inner retaining wall 114. In this way, the waterproof speaker 1 of the present invention allows the bottom of the annular metal bracket 121 of the diaphragm assembly 12 to be set in the annular groove 113, and the inner edge of the bottom of the annular metal bracket 121 abuts against the annular inner retaining wall 114, so that the movement of the annular metal bracket 121 is restricted by the annular inner retaining wall 114, and then the cooperation of the speaker seat assembly 11 and the diaphragm assembly 12 can be used to effectively increase the structural strength of the waterproof speaker 1, thereby improving the water pressure resistance and achieving a better waterproof effect.

[0056] In addition to the above embodiments, in one embodiment of the present invention, the outer periphery of the annular side magnetic conductive plate 112 may be provided with a plurality of snap-in units 1122 and a plurality of exposed units 1123, each snap-in unit 1122 is snap-fitted to the speaker seat 111, and each exposed unit 1123 is located between two snap-in units 1122 and exposed to the annular groove 113 of the speaker seat 111. In this way, the waterproof speaker 1 of the present invention allows the bottom of the annular metal bracket 121 of the diaphragm assembly 12 to be arranged in the annular groove 113 and then connected to each exposed unit 1123 of the annular side magnetic conductive plate 112 to maximize the magnetic conductive effect. In addition, when the speaker seat 111 and the annular side magnetic conductive plate 112 are integrally injection molded, each snap-in unit 1122 can enhance the bonding strength between the speaker seat 111 and the annular side magnetic conductive plate 112.

[0057] In addition to the above embodiments, in one embodiment of the present invention, the inner periphery of the annular side magnetic conductive plate 112 is exposed inside the speaker seat 111. In this way, the waterproof speaker 1 of the present invention can maximize the magnetic conductive effect.

[0058] In addition to the above embodiments, in one embodiment of the present invention, the outer periphery of the annular groove 113 may be provided with an annular outer retaining wall 115, the annular outer retaining wall 115 corresponds to the annular inner retaining wall 114, the inner edge of the bottom of the annular metal bracket 121 abuts against the annular inner retaining wall 114, the outer edge of the bottom of the annular metal bracket 121 abuts against the annular outer retaining wall 115, and the bottom of the annular metal bracket 121 is limited between the annular outer retaining wall 115 and the annular inner retaining wall 114. In this way, the waterproof speaker 1 of the present invention can further limit the left and right movement of the annular metal bracket 121 through the cooperation of the annular inner retaining wall 114 and the annular outer retaining wall 115, and then effectively increase the structural strength of the waterproof speaker 1 through the cooperation of the speaker seat assembly 11 and the diaphragm assembly 12, thereby improving the water pressure resistance and achieving a better waterproof effect.

[0059] In addition to the above embodiments, in one embodiment of the present invention, the annular metal support 121 may include an annular edge portion 1211, an annular inner edge portion 1212 and an annular outer edge portion 1213, the annular inner edge portion 1212 is transversely arranged at the inner edge of the top of the annular edge portion 1211 (extending inward), and the annular outer edge portion 1213 is transversely arranged at the outer edge of the bottom of the annular edge portion 1211 (extending outward), so that the cross-section of the annular metal support 121 presents a Z-shaped structure, the diaphragm 122 covers the annular edge portion 1211 and the annular inner edge portion 1212, and the inner edge of the annular outer edge portion 1213 abuts against the annular inner retaining wall 114, and the outer edge of the annular outer edge portion 1213 abuts against the annular outer retaining wall 115. In this way, the waterproof speaker 1 of the present invention can increase the bonding area and strength between the diaphragm 122 and the annular metal bracket 121 through the annular edge portion 1211 and the annular inner edge portion 1212, and at the same time utilize the annular outer edge portion 1213 to expand the fitting area between the annular metal bracket 121 and the speaker seat 111, so that the speaker seat assembly 11 and the diaphragm assembly 12 have better bonding strength, and the cooperation of the annular inner retaining wall 114, the annular outer retaining wall 115 and the annular outer edge portion 1213 further limits the left and right movement of the annular metal bracket 121, and then the cooperation between the speaker seat assembly 11 and the diaphragm assembly 12 effectively increases the structural strength of the waterproof speaker 1, thereby improving the water pressure resistance and achieving a better waterproof effect.
