DOLL CIRCUIT AND DOLL

摘要

A doll circuit and a doll are provided. The doll circuit comprises a bluetooth receiving circuit, an audio amplifying circuit and a motor. The bluetooth receiving circuit includes an audio output port connected with the input port of the audio amplifying circuit. The output port of the audio amplifying circuit is connected with the motor to drive the motor. The children's interest in playing dolls would be aroused because the bluetooth receiving circuit is adopted to receive audio and drive the motor. Furthermore, the motor is isolated from a loudspeaker by an AC coupling circuit and therefore the doll circuit has the functions of driving the motor by audio and audio playing at the same time.
