What does an object have to do to produce sound?
Hi, A loud speaker is essentially just a drum that vibrates at varying frequencies to produce a range of sounds. This is usually done by Magnets (which is why you should NEVER put a speaker next to a TV - the magnets affect the RGB screens) The size of the speaker usually dictates how well it performs at certain tones. General Rule of Thumb is that the bigger the diameter of a speaker, the better it performs with lower range tones, and vice versa. Of course this all goes out the window when it comes to Flat panel speakers - I've no idea how they work.
