Abstract:
The invention discloses a two-wire type microphone with ultrasonic identification, comprising: an acoustic transducer for capturing an acoustic signal; a signal processing chip, connected to a signal output terminal of the acoustic transducer, wherein the signal processing chip comprises a signal output terminal pin, a ground pin and an ultrasonic generator, wherein the ultrasonic generator is the configured for generating an ultrasonic signal, and a control terminal of the ultrasonic generator is connected to the signal processing chip. The beneficial effects of the present invention includes: the ultrasonic signal generated by the ultrasonic generator is utilized to match the ultrasonic signal with the encoding unit in the signal processing chip for identification, and a remote authentication by the client is useful for matching the electronic device with the microphone. Furthermore, the signal output terminal pin and the ground pin are introduced into the microphone in the prior art, and the signal output terminal pin is also used for a communication line and a power line, thereby further saving the cost.

Claim (Index 7):
