A TRANSDUCER is an electronic device that utilizes sensors to convert mechanical energy in one form to another energy form, typically in the form of an electronic signal.
Transducers are typically used to convert a physical parameter such as temperature, pressure, flow, light intensity, etc. into an electrical signal. A speaker changes electrical energy from an amplifier into mechanical energy or sound waves. The electrical energy in the amp causes the speaker cone to move in and out creating air waves that our ears perceive as sound. A microphone is the reverse of a speaker. It is a transducer that converts acoustic energy in the form of sound waves from a human voice and turns it into electrical energy or electrical impulses.
