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.
Sound, by definition, is physical vibrations which can be perceived. To produce sound, an object must vibrate and cause those vibrations to get as far as a human ear. Normally, this involves making the air between the ear and the object vibrate, but if the object is in contact with the body, it is quite possible for the vibrations to move through flesh and bone (especially bone) to get perceived.
So the key elements are:
The object must vibrate.
The vibrations of the object must be perceived.
a high sound
True. A vibrating string can produce a sound. This is how string instruments such as a guitars and violins work. Although such strings are made of metal (like steel wire) or plastic (like nylon), the principal is the same for all of them.
The vibrations from your lips are what creates sound
Most percussion and string instruments operate of vibrations to produce sound. Drum heads, xylophone bars, strings and reeds all vibrate on instruments that use them to produce sound.

if they are in a void no matter how much the object vibrates it won't produce any sound waves
Well, it's not necessary for the whole object to vibrate, but the part of it that's producing the sound does. Example: I'm not vibrating when I produce sound, but my vocal chords are, otherwise there's no sound. So the answer to what you're trying to ask is: No.
An object vibrates to produce sound. So a soundmaking object is different from the one that is silent because it produces vibrations that the silent object does not.

Sound is produced when an object moves or vibrates. Without movement there could be no sound. When an object moves or vibrates, the air molecules around the object also vibrate. Vibrating objects (as long as they are not in a vacuum) produce sound.
solid
vibration of the object and a medium such as air
it produces a low pitch sound
a vibrating body produces sound. ie only if an object vibrates will it produce sound. the faster the object vibrates, the louder the sound and vice-versa. the no of vibrations per seceon is called frequency. thus if an object has a higher frequency, then it produces a louder and shriller sound...
