How Do Sound Speakers Work?

Sound speakers work on the premise of the fluctuations in the movement of waves of air pressure. Sound travels in fluctuating waves of air pressure. We hear different sounds from our sound speakers. These different sound speakers vary according to the two factors, namely the amplitude of the sound waves and the frequency of the sound waves.

Microphones also follow the same basic principle. In other words, microphones translate sound waves into electrical signals. These electrical signals are then encoded onto compact discs (CD's), tapes, long-playing discs (LP's), etc. The player coverts this information which is stored back into an electrical current. This electrical current is then used in the stereo system.

A speaker is basically the final machine in the process of translation. The working of a speaker is basically the reverse of that of a microphone. In other words, it takes the electrical signal, translates it back into physical vibration and produces sound waves. Assuming everything is working perfectly well, the speaker should produce nearly the same vibrations that were originally recorded by the microphone and encoded on the tape, Compact disc, long-playing disc, etc.
