Speakers are electro-acoustic transducers. The scientific name tells us that the speaker is a device that converts electrical impulses into sound. It consists of a magnet and a diaphragm for converting electrical signals to sound waves, then radiate them into the air.
The human ear can hear sounds at frequencies from 20 Hz to 20 kHz. Therefore, speakers are constructed to encompass this ideal sound spectrum. The lower the frequency, the deeper the tone. It is very effective for movies with action and explosions etc., and for listening to music with deep bass and drums.
