Horn Speaker Amplifier Circuit Diagram. For speaker use an 8 ohms 1 to 5 watt loud speaker. One way all call to all speakers available.
Connect the circuit diagram as in the one marked with amplifier with gain 20 and you get 20 fold the signal. This is speaker protector circuit diagram using ne555n ic. For splitting the signal you can use resistors for basic splitting.
Use a low power audio amplifier and use read more.
Volume controls and amplifiers in each speaker. The circuit is quite simple and easy to built and of course inexpensive. Circuit diagram with parts list. Circuit diagram for electronic horn circuit construction and working here first timer ic produce pulse output and second timer ic produce high frequency pulse then the output from the second timer ic fed to the loud speaker.
