What is Speaker and Headphone?
Briefly, speakers are devices that recreate a sound by converting electric signals into vibrations in the air with the use of an elastic diaphragm. The vibrations are translated into sound by the human ear. The human ear is capable of distinguishing vibrations ranging from 20 Hz to 20000 Hz. (1 Hertz (Hz) denotes one vibration per second).
