Description

technical field

[0001] The invention relates to the technical field of microphone detection, in particular to an automatic feeding microphone sorting device. Background technique

[0002] Microphones are also called microphones or condenser microphones. According to the connection method, microphones can be divided into: double-solder microphones, single-solder microphones, and pin-type microphones. Pin-type microphone, as the name suggests, there are two pins on the microphone, which can be used after being directly inserted into the circuit board and soldered. It has the characteristics of convenient connection and no welding wire, and is widely used. At present, the signal-to-noise ratio is usually used as an indicator to judge the quality of the microphone. The signal-to-noise ratio is also called decibel or sensitivity, expressed in DB. After a batch of microphones are processed, it is necessary to sort the DB values ​​of the microphones to select products that meet cu...
