Problems solved by technology

[0002] Acoustic components currently on the market, such as buzzers, speakers, receivers, etc., are difficult to meet a high waterproof level
A small number of piezoelectric elements are designed with stainless steel piezoelectric substrates to manufacture bare cavities, which can achieve a certain waterproof effect, but because there is no real resonant cavity, the output sound pressure is low, and generally high-voltage drives are required, and a built-in boost circuit is required, resulting in Its high cost and bulky make it difficult to be widely used

Embodiment Construction

[0014] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0015] refer to figure 1 with figure 2 As shown, an acoustic waterproof structure includes an acoustic cavity main body 1 , an acoustic cavity 2 and a closed sound source 3 in the rear cavity.

[0016] Further, the acoustic cavity main body 1 is provided with an array of microholes 11 and a microhole sound guide post 12 .

[0017] Further, the acoustic cavity 2 is closed.

[0018] Further, the array of micro-holes 11 and the micro-hole sound guide post 12 form a breathable and waterproof array of micro-sound holes.

[0019] Principle of the present invention:

[0020] When working, the closed sound source 3 in the back cavity produces original audio vibrations, and the sound signal is amplified after the resonance of the sound cavity 2, and then emitted by the breathable and waterproof array micro-sound holes composed of the arr...

Abstract

The invention discloses an acoustical waterproof structure which comprises a vocal cavity main body, a vocal cavity and a rear cavity sealing sound source. The vocal cavity main body is connected with the rear cavity sealing sound source, and a vocal cavity is formed. The vocal cavity main body is provided with array micropores and a micropore sound guiding column. According to the technical scheme, the principle that the micropores are breathable and watertight is utilized, conventional acoustical cavity sound holes are modified into the dense array micropores, the array micropores effectively prevent water from entering an inner cavity while guaranteeing sound output, the waterproof and dustproof effects are achieved, and the acoustical waterproof structure can be widely applied to the design of various acoustic components.

Description

technical field [0001] The invention relates to a waterproof structure, in particular to an acoustic waterproof structure. Background technique [0002] Acoustic components currently on the market, such as buzzers, speakers, receivers, etc., are difficult to meet a high waterproof level. A small number of piezoelectric elements are designed with stainless steel piezoelectric substrates to manufacture bare cavities, which can achieve a certain waterproof effect, but because there is no real resonant cavity, the output sound pressure is low, and generally high-voltage drives are required, and a built-in boost circuit is required, resulting in Its high cost and bulky make it difficult to be widely used. Contents of the invention [0003] The object of the present invention is to overcome the problems existing in the prior art and provide an acoustic waterproof structure. [0004] In order to achieve the above-mentioned technical purpose and achieve the above-mentioned techn...
