Abstract
Description
Technical Field
[0001] This utility model relates to the field of diaphragm bonding, specifically a diaphragm bonding device. Background Technology
[0002] Diaphragms can be categorized by industry: electroacoustic diaphragms; mechanical diaphragms; microporous diaphragms for filtration and isolation; and optics diaphragms. For mechanical diaphragms, they are circular, elastic, and sensitive elements. When the two sides of the diaphragm are subjected to different pressures, the diaphragm shifts towards the side with lower pressure, causing a displacement at its center that is proportional to the pressure difference. Diaphragms are mainly classified into three types: flat diaphragms, chain-type diaphragms, and corrugated diaphragms. Flat diaphragms can be further classified into various forms based on factors such as whether the periphery is fixed and supported, whether there is an opening in the center, and the distribution of stress across the diaphragm area. The most commonly used type is a flat diaphragm composed of a circular thin plate with a uniform cross-section fixed at the periphery.
