Utility model content
The main purpose of the utility model is to provide a kind of electro-acoustic elements, by setting EMI FILTER and resist dry
Gauze screen is disturbed, the effective performance for promoting electro-acoustic element main body and resisting outside electromagnetic interference passes through setting Miniature condenser and ring
Oxygen thermal grease layer, the effective heat sinking function for promoting electro-acoustic element main body are effectively reduced miniature cold by the way that noise reducing plate is arranged
The noise that condenser generates when working, plays extraordinary Noise Reduction, can effectively solve the problems in background technique.
To achieve the above object, the technical solution that the utility model is taken are as follows:
A kind of electro-acoustic element, including electro-acoustic element main body, electro-acoustic element body exterior both ends be connected have connection every
Plate is inlaid with anti-interference gauze screen inside the connecting partition, and side is equipped with EMI Filtering outside the connecting partition
Device.
Further, electro-acoustic element body exterior side linking has epoxy thermal grease layer, the epoxy thermal conductive silicon
The linking of rouge layer side has hot channel, and the hot channel side is equipped with Miniature condenser, sets outside the Miniature condenser
There is noise reducing plate.
Further, the noise reducing plate is made of vacuum interlayer, silencing cotton interlayer and mineral wool interlayer, the mineral wool folder
The linking of layer bottom has vacuum interlayer, and the vacuum interlayer bottom linking has silencing cotton interlayer, and the mineral wool interlayer passes through vacuum
Interlayer is connect with silencing cotton interlayer.
Compared with prior art, the utility model has the following beneficial effects:
1. effective promotion electro-acoustic element main body is resisted extraneous by setting EMI FILTER and anti-interference gauze screen
The performance of electromagnetic interference, open control EMI FILTER work, can effectively reduce or decayed it is all to enter or
The hazardous noise signal of electro-acoustic element main body is left, anti-interference gauze screen can be good at reinforcing the anti-interference of connecting partition
Can, convenient for the use of electro-acoustic element main body.
2. by setting Miniature condenser and epoxy thermal grease layer, the effective heat dissipation function for promoting electro-acoustic element main body
Can, epoxy thermal grease layer has extraordinary heating conduction, and the heat generated when can be by electro-acoustic element body of work is quick
Control Miniature condenser work is opened in export, and Miniature condenser can reduce the heat inside hot channel, thus effectively
The heat for reducing epoxy thermal grease layer, enables electro-acoustic element main body rapid cooling.
3. effectively reducing the noise generated when Miniature condenser work by setting noise reducing plate, playing extraordinary drop
The effect of making an uproar, noise reducing plate inside silencing cotton interlayer and mineral wool interlayer all have extraordinary sound deadening, can be good at reducing
Volume can enhance erasure effect by vacuum interlayer, hinder the propagation of sound wave, effectively avoid noise to electro-acoustic element main body
Influence.
