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.

The vibrations from your lips are what creates 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.
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.
The strings.
A horn or a siren can produce a loud sound.
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.

Drums.
Musical instruments, speakers, bells, and buzzers are examples of objects that can produce sound when vibrating.
An object must be vibrating in order to produce sound. This vibration creates a disturbance in air particles, which travels in the form of sound waves to our ears, allowing us to hear the sound.
if they are in a void no matter how much the object vibrates it won't produce any sound waves
The length of an object affects the pitch of the sound produced by changing the wavelength of the sound wave. A shorter object will produce a higher pitch sound because it vibrates at a faster rate, creating shorter wavelengths. Conversely, a longer object will produce a lower pitch sound due to longer wavelengths and slower vibrations.
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.
Not all vibrating objects produce sound. Sound is produced when a vibrating object creates compressional waves in a medium, such as air. If the vibrating object is not in contact with a medium that can carry sound, then no sound will be produced.
