Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
Example (b):
as shown in figure 1, a circuit for driving a motor to massage by using audio rhythm signals comprises a plurality of audio source signal units, wherein the audio source signal units are respectively connected with a processing chip A and a processing chip B through audio source switching channels, the processing chip A is respectively connected with a loudspeaker driving circuit and an input end of an audio amplification circuit, an output end of the audio amplification circuit is connected with an input end of an MCU chip, an output end of the MCU chip outputs PWM (pulse width modulation) signals to a massage motor, and the processing chip B is connected with the motor driving circuit through a motor audio output end.
The processing chip A and the processing chip B both adopt PT2314E chips.
The chips of the horn driving circuit and the motor driving circuit are all any one of MIX3015, CS8673, CS8655 and TDA 729.
The sound source signal unit comprises a Bluetooth sound source module, an MP3 chip sound source module and a TF card reader sound source module.
The output end of the motor driving circuit is connected with a plurality of motors, and the output end of the horn driving circuit is connected with a plurality of horns.
The MCU chip is also connected with the mute pins of the horn drive circuit and the motor drive circuit respectively through the IO port.
The MCU chip is also connected with the processing chip A and the processing chip B through communication ports respectively.
As shown in fig. 2-6, in this embodiment, the sound source signal unit employs a bluetooth sound source module and an MP3 chip sound source module, the bluetooth sound source module and the MP3 chip sound source module are connected to a processing chip a and a processing chip B through sound source switching channels, the processing chip a and the processing chip B employ PT2314E chips, the MCU chip can control the processing chip a to switch arbitrarily through a communication port (I2C port), select a bluetooth sound source or an MP3 chip sound source, and output the sound source to a speaker driving circuit through a speaker audio output end, the speaker driving circuit employs a CS8673 chip, amplify a sound source signal by using a D-type power amplifier, drive 2 speakers to play music, the MCU chip further controls a mute port of the speaker driving circuit through an IO port, close a corresponding speaker, and avoid noise of the speaker.
