Production process of electroacoustic component

Abstract

The invention relates to a production process of an electroacoustic component which comprises a shell, a field effect transistor, a polar plate, a vibrating diaphragm, a first terminal pin, a second terminal pin and a spacing ring, wherein a sound conducting hole is arranged at the upper part of the shell. The production process comprises the following steps: manufacturing the field effect transistor, assembling the polar plate, arranging conductive adhesive, assembling the spacing ring, installing the vibrating diaphragm and finally packaging. A drain electrode of the field effect transistorforms the first terminal pin of the electroacoustic component, a source electrode forms the second terminal pin of the electroacoustic component, the polar plate is assembled on a bearing end surfaceof the grid electrode, the bearing end surface of the grid electrode performs the function of supporting the polar plate, and the drain electrode and the source electrode can directly form the terminal pins of the electroacoustic component, thereby saving the steps in a traditional processing method, decreasing components and parts, simplifying the structure, lowering the cost, additionally decreasing the processing working procedures, improving the processing efficiency and easily realizing automatic production.

Problems solved by technology

[0013] Due to the complex structure of this electro-acoustic element, the traditional production process is relatively cumbersome, and most of them are manually operated, so it is difficult to realize automatic production, so the production efficiency is low and the production cost is high. For miniature and ultra-thin electro-acoustic elements Said that it is more difficult to assemble, the yield of the product is very low, and it can no longer adapt to the trend of miniaturization of the microphone
