Audio signal amplifying circuit
摘要:
The present disclosure provides an audio signal amplifying circuit for an electronic device including a processing chip and a speaker. The audio signal amplifying circuit includes an amplifying circuit and an inverting circuit connected to the processing chip to get a first control signal and invert the first control signal to generate a second control signal. The first control signal and/or the second control signal are used to control the operation mode of the amplifying circuit to be in an amplifying mode or in a non-amplifying mode.
