Abstract

Disclosed is a microphone sealing device, comprising a sealing sleeve, an elastic body, a compression portion and a positioning portion, wherein the sealing sleeve is sheathed on a microphone; the elastic body abuts between the sealing sleeve and the compression portion; and the compression portion is mounted on a main board by means of the positioning portion. In an embodiment of the present invention, by compressing the elastic body by means of the compression portion, the elastic body transfers a force to the sealing sleeve, and then, the sealing sleeve pushes against a housing, thus realizing the tight press fitting of the sealing sleeve and the housing and achieving a sealing function. The above-mentioned technical solution is highly reliable in terms of sealing and is convenient to disassemble and recycle.

Description

technical field [0001] The technical field of audio equipment of the present invention, in particular, relates to a microphone sealing device. Background technique [0002] MIC (Microphone, microphone) is a very important device in mobile phone products, which can convert sound signals into electro-acoustic signals. The use of MIC by communication manufacturers directly affects the quality of calls. At present, the MICs of mobile phones on the market need to be sealed to prevent signal leakage, or to prevent noise, noise, and even echo phenomena in calls. [0003] There are two common sealing methods, one is to directly contact and seal through foam, and the other is to directly contact and seal through a silicone sleeve. Structures sealed by direct foam contact such as figure 1 As shown, the structure is directly compressed and sealed by the shell 101 and the foam 102, wherein the shell 101 presses the foam 102, the foam 102 presses the MIC103, and the MIC103 is installed...
