Audio Bluetooth Circuit Diagram. This system is based on a stereo class d audio amplifier which is driving a pair of 4ω speakers. I didnot use this circuit in this project because i used mp3 bluetooth kit instead.
I ll go into detail about the right and wrong way to wire speakers and connect them properly to your stereo or amplifier. A block diagram of the system is described in figure 1. Block diagram of wireless bluetooth stereo audio system.
A bluetooth circuit is the central part of a bluetooth and contains components such as the integrated circuit capacitors and source of power the course supports wired in audio wireless stereo bluetooth module and many more.
I ll go into detail about the right and wrong way to wire speakers and connect them properly to your stereo or amplifier. Or simply of wireless audio transmission. It s actually pretty simple once you learn the basics. The audio jack originaly is connected to the bluetooth module in the pins the picture shows with those red arrows so we need to isolate the audio jack disconnecting it from those pins that are inputs so search for those tracks in the circuit board and cut it has i show in the second picture.
