There is a tone generator, which is able to generate different tones using the oscillator clock and um561 to the data given by the ROM.

The UM has 8 pins, and it can intake 3 to 5V as a power um35661 and gives output range It can easily drive magnetic speaker with a help of single NPN transistor. Your email address will not be published. We need only a few additional components as this Integrate Circuits has built in oscillator and selector circuits.

Siren Sound generator circuit can be utilized in several applications, different siren sounds are used for many field based applications, here the following circuit can produce three different siren sounds Police siren, Im3561 engine siren, Ambulance siren.

They are also started I already said that this IC can generate 4 different sirens.

As these signals are very weak to drive a speaker, we need an amplifier. It is a low uk3561 and low power IC which can work down to 2.

Here BC transistor is used as an amplifier. Contents1 Follow Manufacturer Specific Datasheet1. In order to post comments, please make sure JavaScript and Cookies are enabled, and reload the page. This website uses cookies to improve your experience.

By applying these bias to the SEL pins we can get different siren sound effect. Each data stored in the ROM corresponds to each tone and it can be selected by using the address of the data location.
