Description

Technical Field

[0001] The utility model relates to the technical field of speaker washers, in particular to a high-strength waterproof speaker washers. Background Art

[0002] Speakers, also called loudspeakers, are a very commonly used electroacoustic transducer device. There are many types of speakers, and the prices vary greatly. Through electromagnetic, piezoelectric or electrostatic effects, the paper cone or diaphragm can generate mechanical waves. According to the transducer mechanism and structure, they are divided into dynamic (electric), capacitive (electrostatic), piezoelectric (crystal or ceramic), electromagnetic (compression spring), ion and pneumatic speakers. Electric speakers have the advantages of good electroacoustic performance, firm structure and low cost, and are widely used; according to the sound radiation material, they are divided into paper cone, horn and diaphragm; according to the shape of the paper cone, they are divided into round, oval, double paper cone and rubber folded ring; according to the working wavelength, they are divided into long wave, medium wave and short wave, and some are also divided into special recorders, special TVs, ordinary and high-fidelity speakers, etc.; according to the voice coil impedance, they are divided into low impedance and high impedance; according to the effect, they are divided into direct radiation and ambient sound, etc.

[0003] The speaker gasket is installed on the speaker bracket to play the role of sealing and shock absorption. Traditional speaker gaskets are generally made of rubber material, which is set into an annular structure with a size matching the speaker, and then directly placed in the reserved groove of the bracket, and finally fixed with fasteners. There are two installation methods for fasteners. The first is to directly use multiple bolts to penetrate the gasket and fasten it with the bracket to achieve the installation of the gasket. The other is to use another annular shell on the top of the gasket to press the entire gasket to achieve installation. The second installation method can make the gasket play a more stable waterproof and dustproof role, and the sealing performance is better. However, in specific use, during the process of threaded tightening of the annular shell and the bracket, the annular shell will rotate relative to the gasket, or the gasket and the bracket will rotate relative to each other. This rotation will cause greater friction on the gasket, thereby suffering greater wear. Secondly, after the gasket is installed, long-term use will cause the gasket to age. The aged gasket will often break when disassembled, thereby embedding in the reserved groove, so there is inconvenience in use. Utility Model Content

[0024] Reference Figure 1-3The high-strength waterproof speaker gasket includes a first rubber pad 1 and a second rubber pad 2, which are rotatably connected. The first rubber pad 1 and the second rubber pad 2 are both annular structures. The first rubber pad 1 and the second rubber pad 2 are both fixedly sleeved with an annular iron sheet 3. The first rubber pad 1 and the second rubber pad 2 form a gasket, which is placed in a reserved groove of the bracket, and then the annular shell is used to tighten the reserved groove. In this process, the gasket is squeezed, and the gasket will be deformed during the squeezing process, thereby achieving sealing. Since each part of the gasket is subjected to the pressure of the annular shell, the sealing can be enhanced, thereby improving the waterproof performance. Inside the first rubber pad 1 and the second rubber pad 2, a gasket is formed. The first rubber pad 1 and the second rubber pad 2 are each provided with an annular iron sheet 3, so as to enhance their strength and improve the overall stability. The first rubber pad 1 and the second rubber pad 2 can rotate, so the top of the first rubber pad 1 contacts the annular shell, and there is friction between the first rubber pad 1 and the annular shell. Therefore, during the rotation and tightening of the annular shell, the first rubber pad 1 rotates with the annular shell, and the bottom of the second rubber pad 2 contacts the reserved groove. When the gasket is subjected to pressure, friction is generated between the gasket and the reserved groove, so that the second rubber pad 2 can remain stationary relative to the first rubber pad 1, and then the first rubber pad 1 and the second rubber pad 2 rotate when the annular shell rotates, thereby reducing the wear of the gasket caused by friction and improving the service life of the gasket.

[0025] Furthermore, an annular protrusion 5 is provided at the bottom of the first rubber pad 1, and an annular groove 4 is provided at the top of the second rubber pad 2. The first rubber pad 1 and the second rubber pad 2 rotate through the annular protrusion 5 and the annular groove 4 to maintain the stability of the first rubber pad 1 and the second rubber pad 2 when rotating.

[0026] Furthermore, the cross sections of the annular protrusion 5 and the annular groove 4 are both “T”-shaped structures, and the annular protrusion 5 is embedded in the annular groove 4 .

[0027] Furthermore, the surface of the annular protrusion 5 and the inner wall of the annular groove 4 are both coated with a PVC film. By providing the PVC film, the rotational friction between the first rubber pad 1 and the second rubber pad 2 can be reduced.

[0028] Furthermore, an annular boss 6 is provided at the bottom of the second rubber pad 2. By providing the annular boss 6, since the lower dimension of the annular boss 6 is smaller than the upper dimension, the gasket can be conveniently placed in the reserved groove, thereby reducing the position deviation during the placement process.

[0029] Furthermore, the top of the first rubber pad 1 and the bottom of the annular boss 6 are both provided with tooth-shaped protrusions 7. By providing the tooth-shaped protrusions 7, the friction between the first rubber pad 1 and the annular shell can be enhanced so that it rotates with the annular shell, and the friction between the second rubber pad 2 and the reserved groove can be enhanced so that it remains stationary. Moreover, the tooth-shaped protrusions 7 can fill the gaps between each other after being deformed by force, and will not affect the sealing performance of the gasket.

[0030] In summary, the first rubber pad 1 and the second rubber pad 2 form a gasket, which is placed in the reserved groove of the bracket, and then the annular shell is used to tighten the reserved groove. In this process, the gasket is squeezed and deformed during the squeezing process, thereby achieving sealing. Since each part of the gasket is subjected to the pressure of the annular shell, the sealing performance can be enhanced, thereby improving the waterproof performance. An annular iron sheet 3 is provided inside the first rubber pad 1 and the second rubber pad 2, thereby enhancing its strength and improving the overall stability. The first rubber pad 1 and the second rubber pad 2 can rotate, so the top of the first rubber pad 1 contacts the annular shell, and there is friction between the annular shell, so that in the process of rotating and tightening the annular shell, the first rubber pad 1 rotates with the annular shell, and the bottom of the second rubber pad 2 contacts the reserved groove, and when the gasket is subjected to pressure, friction is generated between the reserved groove, so that the second rubber pad 2 can remain motionless relative to the first rubber pad 1, thereby in the annular When the shell rotates, the first rubber pad 1 and the second rubber pad 2 rotate, reducing the wear of the gasket caused by friction and increasing the service life of the gasket. The first rubber pad 1 and the second rubber pad 2 rotate through the annular protrusion 5 and the annular groove 4 to maintain the stability of the first rubber pad 1 and the second rubber pad 2 when rotating. By setting the PVC film, the rotational friction between the first rubber pad 1 and the second rubber pad 2 can be reduced. By setting the annular boss 6, since the lower dimension of the annular boss 6 is smaller than the upper dimension, the gasket can be conveniently placed in the reserved groove to reduce the position deviation during the placement process. By setting the tooth-like protrusion 7, the friction between the first rubber pad 1 and the annular shell can be enhanced so that it rotates with the annular shell, and the friction between the second rubber pad 2 and the reserved groove can be enhanced so that it remains stationary. Moreover, the tooth-like protrusion 7 can fill the gap between each other after being deformed by force, and will not affect the sealing performance of the gasket.
