Description

Easy-to-deform diaphragm follow-up composite tool

Technical Field

The utility model relates to a compound frock specifically is a yielding diaphragm follow-up compound frock.

Background

Diaphragm: a circular membrane-shaped elastic sensing element. When the two sides of the diaphragm are subjected to different pressures (or forces), the diaphragm moves toward the side with lower pressure in a strained manner, so that the center thereof is displaced in a certain relationship with the pressure difference. The membrane mainly has three forms, namely a flat membrane, a vertical chain type membrane and a corrugated membrane. The flat diaphragm can be divided into a plurality of forms according to whether the periphery is fixedly supported or not, whether the center is provided with a hole or not and the stress distribution condition of the diaphragm area is different, wherein the flat diaphragm which is formed by circular thin plates with constant cross sections and fixed on the periphery is most commonly used. The vertical chain type diaphragm is composed of circular plates close to grooves in the edges, elastic strain of the circular plates mainly occurs in annular grooves in the edges, and the diaphragm is commonly used for compressing strain tubes or columns to achieve the purpose of pressure measurement. The hard center portion of the catenary diaphragm translates nearly when moved under pressure, and thus works well for capacitive or piezoelectric sensors. The corrugated diaphragm is pressed with annular concentric corrugations. In order to increase the displacement of the center of the diaphragm, two diaphragms can be welded together to form a diaphragm box or a plurality of diaphragm boxes can be further connected in series to form a diaphragm box group.

When pasting compound to diaphragm and voice coil, present yielding diaphragm and voice coil loudspeaker voice coil adopt the manual work to paste compound mostly, and the compound inefficiency of manual operation, and probably also the voice coil loudspeaker voice coil warp the condition of damaging, therefore we improve this, provide a yielding diaphragm follow-up compound frock.
