General Introduction of electret microphone

Electret condenser microphone is a sound- electrical conversion device. The Electronic condenser microphone is used in telephones, wireless telephones, mobile phones, ear-telephones, PCs, language-learning recorders, radio recorders, cassette recorders, alarms, voice control toys, voice control switches and so on .

Main Parameter of electret microphone

1.What is the Noise Cancelling Electret condenser microphone?

A noise cancelling microphone (also known as pressure gradient or close talking) is a directional microphone designed for use close to the talker's mouth. Its directional pattern looks like a figure 8, and is called cosine or bidirectional.
