Question

Name the appliances which work under the following energy transformation. sound energy into electrical energy electrical energy into mechanical energy

Answer 1

Noise ( sound) energy can be converted into viable source of electric power by using a suitable transducer.

This can be done by using a transducer by converting vibrations caused by noise into electrical energy.

An application is proposed for the same, in which a speaker and a transformer are used to convert noise produced by a car horn into electrical energy.

The vibrations created by noise can be converted into electrical energy through the principal of electromagnetic induction. The received signal was stepped up using a transformer
