Horn Speaker Amplifier Circuit Diagram. Here is a simple circuit diagram of a simple musical horn using two ne555 ics. Two ics are wired as astable mutivibrators.
This is speaker protector circuit diagram using ne555n ic. If you have no audio amplifier then you can make a small amplifier very easily with lm386 ic. Here in this post we can get speaker protection circuit diagram.
The combined effect of the astable multivibrators produces a musical tone at the output.
The circuit is quite simple and easy to built and of course inexpensive. Here is a simple circuit diagram of a simple musical horn using two ne555 ics. This is speaker protector circuit diagram using ne555n ic. Circuit diagram with parts list.
