Problems solved by technology

In the whole assembly process, the process of assembling the insulating gasket 4 has the worst operability, because the insulating gasket 4 has a small diameter, thin thickness, and is attracted to each other due to electrostatic interaction, resulting in extremely low efficiency of the 4 process of installing the insulating gasket

Embodiment Construction

[0022] Hereinafter, the present invention will be described in detail based on the drawings, and the purpose and effects of the present invention will become more apparent.

[0023] Such as figure 2 As shown, the microphone using the combined polarization plate of the present invention includes: dustproof or waterproof cloth 1, housing 2, combined polarization plate 5, printed circuit board 8, insulating film ring 10, and one end of the housing 2 is provided with dustproof or waterproof Cloth 1, the housing 2 is sequentially provided with a combined polarization plate 5, an insulating film ring 10, and a printed circuit board 8. The other end of the housing 2 is sealed. The combined polarization plate 5 includes a polarization plate and an insulating layer. The polarization plate is made of a metal plate. It is composed of a polarizing film, and an insulating layer that is 0.01mm~0.10mm higher than the polarizing film is provided on the polarizing film surface of the polarizing p...

Abstract

The invention discloses a combined polarization plate used for a microphone and a manufacturing method thereof. A polarized membrane is arranged on a metal plate; and an insulating layer is arranged on the polarized membrane. The invention integrates the insulating layer and a polarization plate, effectively solves the problems of small size, light weight, difficult operation of the products of the same type; the insulating layer is attached to the polarization plate to replace the procedure of manually installing the insulating layer, and to avoid the problem that a plurality of insulating washers are installed in the manual operating process. The invention enlarges the working surface of the polarization plate, improves the quality of products, eliminates the processing and assembly procedures of the insulating layer, and further reduces manufacturing cost.

Description

Technical field [0001] The invention relates to a microphone component, in particular to a combined polarization plate for a miniature microphone and a manufacturing method thereof. Background technique [0002] The working principle and background of condenser microphones. Introduction to production technology: see the structure of microphones figure 1 The working principle is: the sound (sound wave) enters the microphone housing 2 through the sound hole at the bottom of the housing 2 through the dust-proof (or waterproof) cloth 1, causing the vibration of the diaphragm on the membrane ring 9. Since the distance between the two poles of the capacitor formed by the vibrating membrane, the insulating washer 4 and the charged polarizing plate 5 changes with the vibration of the vibrating membrane, the voltage between the vibrating membrane and the polarizing plate will change accordingly, and it is completed The conversion of acoustic signals to electrical signals. The changed vol...
