An '''audio speaker''' is an electronic device which produces sound waves. This is accomplished by causing vibrations which cause the air pressure to fluctuate slightly in waves. The more rapid these fluctuations are (the higher the frequency of fluctuation) the higher the received pitch is. The stronger each fluctuation is (the greater the amplitude), the greater the volume of the sound.
