Abstract
A microphone apparatus is provided. Whether an electronic signal converted from an audio signal is in compliance with a preset sound characteristic and a preset voice recognition information is determined. When the electronic signal is in compliance with the preset sound characteristic and the preset voice recognition information, an actuation control signal is outputted, so as to trigger an operation of an external circuit external to the microphone apparatus.
Claims11
A microphone apparatus, adapted to an electronic device, the microphone apparatus comprising:
- a Micro-Electro-Mechanical System (MEMS) circuit, converting an audio signal received by the microphone apparatus to an electrical signal;
- an integrated circuit (IC), coupled to the MEMS circuit, amplifying the electrical signal;
- and
- a voice recognition circuit, coupled to the IC, triggering an operation of an external circuit external to the microphone apparatus,
- wherein the processing unit determines whether the electrical signal is in compliance with a predetermined sound characteristic and whether the electrical signal is in compliance with the sound recognition information while the electronic device is in a sleep mode, wherein the processing unit sends an actuation control signal when the electrical signal is in compliance with the predetermined sound characteristic and the sound recognition information, so that the voice recognition circuit triggers the operation of the external circuit external to the microphone apparatus.
