Description

Waterproof structure of speaker

This creation is to provide a waterproof structure of a speaker, especially a waterproof structure that can achieve water resistance, adjust the pressure difference between the inside and outside of the speaker, avoid affecting the movement of the diaphragm, and improve sound quality distortion and volume reduction.

Due to the increasing demand for waterproof functions in smart watches, the waterproof speakers equipped with them should also be waterproof.

Nowadays, in order to achieve high-strength waterproofing, the entire smart watch usually adopts a completely closed design to prevent water seepage inside the watch and damage to related components when engaging in water activities.

However, this kind of smart watch with a completely closed design also leads to the problem that after the waterproof speaker is loaded into the smart watch, the gas inside the speaker cannot be discharged, which hinders the vibration of the speaker diaphragm. Because the diaphragm is a soft material, when the gas inside the speaker cannot be discharged, there will be a certain air pressure inside the speaker. When the diaphragm vibrates towards the inside of the speaker, it will be hindered by this air pressure, which will lead to problems such as sound quality distortion and low volume. .

Therefore, how to create a waterproof structure of the speaker, in order to achieve not only the water blocking function of the speaker, but also the internal air pressure of the speaker to adjust the pressure difference between the inside and outside of the speaker, so as to avoid affecting the normal movement of the diaphragm, and then The purpose of improving the problems of sound quality distortion and volume reduction will be actively disclosed by this creation.

In view of the shortcomings of the above-mentioned known technology, the creator felt that it was not perfect, so he exhausted his mind to study and overcome it, and then developed a waterproof structure of the speaker, in order to achieve not only the water-blocking function of the speaker, but also the Discharge the internal air pressure of the speaker to adjust the pressure difference between the inside and outside of the speaker, so as to avoid affecting the normal movement of the diaphragm, thereby improving the problem of sound quality distortion and volume reduction.

In order to achieve the above and other purposes, the invention provides a waterproof structure of a loudspeaker, which includes: a diaphragm assembly, a water-blocking breathable film and a speaker base. The diaphragm assembly includes a diaphragm support, a diaphragm and a side sealing ring, the diaphragm is arranged on the top of the diaphragm support, the side sealing ring is arranged on the outer periphery of the diaphragm support, and the diaphragm The diaphragm bracket is provided with a pressure relief structure; the water-blocking and breathable membrane is arranged on the diaphragm support and covers the pressure relief structure; pressure structure.

In the above waterproof structure of the loudspeaker, the diaphragm bracket, the diaphragm and the side sealing ring are integrally injection molded.

In the above waterproof structure of the loudspeaker, the diaphragm and the side sealing ring are made of silicone rubber, and the hardness of the diaphragm and the side sealing ring is 50 degrees.

In the above waterproof structure of the loudspeaker, the pressure relief structure is in the shape of a round hole and communicates with the top and bottom of the diaphragm support.

In the above-mentioned waterproof structure of the loudspeaker, there is a communication groove between the bottom of the pressure relief structure, the bottom of the diaphragm support and the bottom of the horn base.

In the above waterproof structure of the loudspeaker, the water-blocking and gas-permeable membrane is a mesh cloth made of porous polytetrafluoroethylene.

In the above waterproof structure of the loudspeaker, the water-blocking gas-permeable film is arranged on the top of the diaphragm support and is located between the diaphragm and the side sealing ring.

In the above waterproof structure of the loudspeaker, the inner edge of the horn base is provided with a ring-shaped magnetic guide, and the ring-shaped magnetic guide corresponds to the vibration area.

In this way, the waterproof structure of the speaker in this creation can not only use the water-blocking breathable film as the water-blocking function of the speaker, but also use the pressure relief structure, the cooperation of the water-blocking breathable film and the vibration area to discharge the internal air pressure of the speaker, so as to Adjusting the pressure difference between the inside and outside of the speaker can avoid affecting the normal movement of the diaphragm, thereby improving the problems of sound quality distortion and volume reduction.
