[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.

[0047] Please refer to Figures 1 to 6 As shown in the figure, the present invention provides a waterproof speaker 1, which includes: a speaker seat 11, a diaphragm assembly 12, a voice coil 13 and a magnetic return assembly 14.

[0048] The speaker base 11 may be a roughly rectangular ring, and an annular washer 111 may be disposed on the inner periphery of the speaker base 11. The speaker base 11 and the annular washer 111 may be integrally injection-molded to enhance the structural strength of the speaker base 11. Furthermore, a plurality of fastening assemblies 112 may be provided between the speaker base 11 and the annular washer 111 to enhance the bonding strength between the speaker base 11 and the annular washer 111.

[0049] The diaphragm assembly 12 can be a slightly rectangular body and includes a diaphragm 121, a dome 122 and a waterproof breathable membrane 124. The diaphragm 121 is arranged on the top of the speaker seat 11. The dome 122 is assembled with the bottom surface of the top of the diaphragm 121 and exposed at the center of the diaphragm 121. The portion of the dome 122 exposed from the diaphragm 121 is provided with at least one air hole 123. The waterproof breathable membrane 124 is assembled with the portion of the top of the dome 122 exposed from the diaphragm 121 and covers the air hole 123. In a preferred embodiment, In an embodiment, the diaphragm 121 may be provided with a diaphragm bracket 1211, and the diaphragm 121, the diaphragm bracket 1211 and the ball top 122 may be integrally injection molded to increase the structural strength of the diaphragm assembly 12, wherein the diaphragm 121 may be made of silicone material, the diaphragm bracket 1211 may be made of metal material (such as stainless steel (SUS304)) or plastic material, and the ball top 122 may be a polymer film (PEN), but the materials of the diaphragm 121, the diaphragm bracket 1211 and the ball top 122 are not limited to this.

[0050] The voice coil 13 can be a rectangular ring and assembled at the bottom of the dome 122 .

[0051] The magnetic return assembly 14 is assembled to the bottom of the speaker base 11 and includes a magnetic base 141 and a magnetic unit 142. The magnetic unit 142 is disposed on the magnetic base 141. The voice coil 13 is movably disposed outside the magnetic unit 142. The magnetic unit 142 may include a main magnet 1421, a main magnetic plate 1422 and two auxiliary magnets 1423. The main magnet 1421 is disposed on the magnetic base 141, the main magnetic plate 1422 is disposed on the top of the main magnet 1421, and the auxiliary magnets 1423 are respectively spaced apart on both sides of the main magnet 1421. The voice coil 13 is movably disposed in a magnetic gap 143 between the main magnet 1421 and the auxiliary magnets 1423. The annular washer 111 is disposed on the top of each auxiliary magnet 1423.

[0052] When the waterproof speaker 1 is in use, it can be combined with a sound box (not shown). After the two silk threads 131 of the voice coil 13 receive external electronic signals, the magnetic force provided by the magnetic base 141, magnetic unit 142 and ring washer 111 of the magnetic return assembly 14 allows the electromagnetic action of the voice coil 13 to cooperate with the magnetic return assembly 14 to drive the diaphragm 121 to move, thereby causing the waterproof speaker 1 to produce sound.

[0053] When the waterproof speaker 1 performs the above-mentioned operation, since the air hole 123 is formed on the dome 122 of the diaphragm assembly 12 and the waterproof breathable membrane 124 is adhered to the air hole 123, the waterproof speaker 1 of the present invention can utilize the air hole 123 to allow gas molecules when the waterproof speaker 1 produces sound to freely enter and exit the interior and exterior of the waterproof speaker 1, thereby balancing the air pressure inside and outside the waterproof speaker 1 and effectively solving the problem of uneven air pressure inside and outside. At the same time, the waterproof breathable membrane 124 can be used to prevent external moisture from penetrating into the interior of the waterproof speaker 1, thereby achieving a pressure balance between the interior and exterior of the waterproof speaker 1 to avoid affecting the output volume of the waterproof speaker 1.

[0054] In addition to the above embodiment, in one embodiment of the present invention, the outer periphery of the top of the speaker base 11 may be provided with an annular assembly groove 113, and the inner periphery of the bottom of the diaphragm assembly 12 may be connected to the annular assembly groove 113. In this way, the waterproof speaker 1 of the present invention can firmly seat the diaphragm assembly 12 in the annular assembly groove 113 of the speaker base 11, thereby increasing the stability of the diaphragm assembly 12 during operation.

[0055] In addition to the above embodiments, in one embodiment of the present invention, the diameter of each air hole 123 can be 0.15 mm; since a too large aperture of the air hole 123 will affect the rigidity of the diaphragm assembly 12, but if the air hole 123 is too small, it will be detrimental to the ingress and egress of gas. Therefore, in this embodiment, a cold laser can be used to punch seven air holes 123 with an aperture of 0.15 mm on the dome 122, and each air hole 123 can be arranged in a straight line, but is not limited to this. Each air hole 123 can also be arranged in a double row of straight lines or in other patterns. In this way, the waterproof speaker 1 of the present invention can utilize each air vent 123 to allow gas molecules to freely enter and exit the inside and outside of the waterproof speaker 1 when the waterproof speaker 1 makes sound, so as to balance the air pressure inside and outside the waterproof speaker 1, and effectively solve the problem of uneven air pressure inside and outside. At the same time, the waterproof breathable membrane 124 can be used to prevent external moisture from penetrating into the interior of the waterproof speaker 1, thereby achieving a pressure balance between the inside and outside of the waterproof speaker 1 to avoid affecting the output volume of the waterproof speaker 1.

[0056] In addition to the above embodiments, in one embodiment of the present invention, the waterproof breathable membrane 124 can be made of a porous polymer film material that is water-resistant and breathable, preferably, but not limited to, expanded polytetrafluoroethylene (ePTFE). The waterproof breathable membrane 124 can block larger water molecules from entering the diaphragm assembly 12, preventing them from flowing into the waterproof speaker 1. Furthermore, the nanoscale pores of the waterproof breathable membrane 124 allow gas molecules to freely enter and exit the diaphragm assembly 12, thereby balancing the air pressure inside and outside the waterproof speaker 1.

[0057] In addition to the above embodiments, in one embodiment of the present invention, the waterproof breathable membrane 124 may include an annular joint 1241, a porous polymer film 1242 and an annular adhesive 1243. The porous polymer film 1242 is arranged in the annular joint 1241, and the annular adhesive 1243 is arranged at the bottom of the annular joint 1241. The annular joint 1241 can be combined with the annular adhesive 1243 to the top of the spherical top 122, so that the waterproof breathable membrane 124 can be easily attached to the spherical top 122, and the porous polymer film 1242 can be spaced at an appropriate distance to cover each air hole 123. In this way, the waterproof speaker 1 of the present invention can utilize each air vent 123 to allow gas molecules to freely enter and exit the inside and outside of the waterproof speaker 1 when the waterproof speaker 1 makes sound, so as to balance the air pressure inside and outside the waterproof speaker 1, and effectively solve the problem of uneven air pressure inside and outside. At the same time, the waterproof breathable membrane 124 can be used to prevent external moisture from penetrating into the interior of the waterproof speaker 1, thereby achieving a pressure balance between the inside and outside of the waterproof speaker 1 to avoid affecting the output volume of the waterproof speaker 1.

[0058] In addition to the above embodiments, in one embodiment of the present invention, a groove 1424 may be provided on the top of the main magnetic plate 1422. The cross-section of the groove 1424 may be V-shaped and correspond to each air hole 123. Since burrs are easily generated on each air hole 123 when the air holes 123 are opened by laser in the present invention, the groove 1424 is provided on the main magnetic plate 1422 to prevent the burrs from touching the main magnetic plate 1422 and causing distortion when the waterproof speaker 1 vibrates.

However, those skilled in the art should understand that these embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of the present invention. It should be noted that any equivalent variations and substitutions to these embodiments are intended to fall within the scope of the present invention.
