Microphone polar plate assembly and method for machining polar plate unit by using same

Abstract

The invention discloses a microphone polar plate assembly. The microphone polar plate assembly comprises more than two polar plate units, wherein the polar plate units are square and are closely arranged in upward-downward and left-right directions. According to the microphone polar plate assembly, fixing parts for fixing the polar plate units are reduced, and remainders are reduced; meanwhile, the polar plate assembly is cut into single polar plate units by using a cutting tool, so that the operation is simple; and when the polar plate units are matched with diaphragms, the polar plate units are not matched with the diaphragms 3 in a complete overlap manner, so that the parasitic capacitance between the polar plate units and the diaphragms can be reduced.

Description

technical field [0001] The invention relates to the technical field of microphones, and more specifically, to a microphone plate assembly and a method for processing a plate unit by using the assembly. Background technique [0002] With the progress of society and the development of technology, in recent years, as the volume of electronic products such as mobile phones and notebook computers has been continuously reduced, people have higher and higher requirements for the performance of these portable electronic products, which also require matching electronic products. Parts continue to shrink in size, performance and consistency. Under this background, many new products have been released in the field of microphone products, which are one of the important parts of the above-mentioned portable electronic products. [0003] A conventional microphone has a parallel plate capacitor composed of a diaphragm, a gasket and a plate unit. As one of the important components in a par...

Problems solved by technology

[0003] A conventional microphone has a parallel plate capacitor composed of a diaphragm, a gasket and a plate unit. As one of the important components in a parallel plate capacitor, the plate unit is favored by the majority of manufacturers. In order to facilitate mass production, usually Combining multiple plate units into plate assemblies is produced at the same time, such as figure 1 As shown, this pole plate assembly includes more than two pole plate units 1 and fixing parts 2 for fixing the pole plate units 1. The conventional pole plate units 1 are square, and the pole plate units 1 are respectively passed through the fixing parts. 2. Fixing. During application, each plate unit 1 is punched out from the fixed part 2 in sequence. The plate assembly in this way increases the area of ​​the fixed part because each plate unit 1 is respectively fixed on the fixed part 2. , causing waste of material
