Receiver

DC12V comes In and gets 5V through 78L05 voltage regulator to supply power to two Bluetooth receiver ships.
The signal from the handheld microphone received by the two Bluetooth connection chips Is demodulated by the chip and combined to output the analog signal.
The product uses OP7326 as the main chip. The chip complies with the V5.3+BR+EDR standard and supports A2DP stereo.
The circuit uses quartz crystal to lock the frequency.

Transmitter

Two batteries power supply, after HX4004 voltage boost to the Bluetooth transmitter chip power supply.
The MIC signal enters the modulation of the Bluetooth transmitter chip and is transmitted out.
The product uses OP7326 as the main chip. The chip complies with the V5.3+BR+EDR standard and supports A2DP stereo.
The power component is 7133. The circuit uses quartz crystal to lock the frequency.
