A tweeter is a specially designed speaker that is much not only much smaller than the woofer but is tasked with only reproducing audio frequencies above a certain point, including, in some cases, sounds that human ear cannot directly hear, but can sense.
Another reason that a tweeter is beneficial is that since high-frequencies are highly directional, tweeters are designed to disperse high-frequency sounds into the room so that they are heard accurately. If the dispersion is too narrow, the listener has a limited amount of listening position options. If the dispersion is too wide, the sense of direction of where the sound is coming from is lost.
Types of Tweeters:
Cone - A smaller version of a standard speaker.
Dome - The voice coil is attached to a dome that can be made of fabric or a compatible metal (such as the one shown in the photo).
Piezo - Instead of a voice coil and cone or dome, an electrical connection is applied to a piezoelectric crystal, which in turn vibrates a diaphragm.
Ribbon - Instead of a traditional diaphragm, a magnetic force is applied to a thin ribbon(s) to create sound.
