Electronic sirens incorporate circuits such as oscillators, modulators, and amplifiers to synthesize a selected siren tone (wail, yelp, pierce/priority/phaser, hi-lo, scan, airhorn, manual, and a few more) which is played through external speakers. It is widely used for many industrial applications.

Unlike electromechanical sirens, electronics sirens are not driven by any motors. The life span of electronic sirens is longer.
