Components of a loudspeaker. Electrical signals sent through the coil cause it to act as an elipsis

In sound reproduction, device for converting electrical energy into acoustical (sound) signal energy that is radiated into a room or open air (see acoustics). The part of the speaker that converts electrical into mechanical energy is frequently called the motor, or voice coil. The motor vibrates a diaphragm that vibrates the air in immediate contact with it, producing a sound wave corresponding to the pattern of the original speech, music, or other acoustic signal.
