Neodymium magnet speaker audio magnetic speaker motor

Neodymium magnet speaker are widely used in home audio, car audio etc.

What Is a Tweeter?
A tweeter is a loudspeaker that reproduces only higher audio frequencies. Because it is limited to high frequencies, it must be combined with speakers that reproduce other frequencies in order for the full range of recorded audio to be audible. The average tweeter outputs frequencies from approximately 2,000 hertz (Hz) and above. 20,000 Hz is considered to be the upper limit of human hearing, but some tweeters can produce frequencies even higher.

A full-range stereo or home theater system uses at least one other speaker in conjunction with each tweeter to produce a full range of sound. In a 2-way speaker, the high frequencies, also called treble, are paired with a speaker known as a woofer that reproduces low end or bass frequencies. More complex speakers use other drivers in addition to the woofer and tweeter to reproduce midrange frequencies. In home stereo speakers, drivers usually share a common enclosure. In some car stereo systems, however, each component may have separate housing to provide additional flexibility in directing the sound.

Car Tweeter

•There are several different types of tweeter available. A cone tweeter has the appearance of a typical loudspeaker — a paper speaker within a metal frame — but is made with a lighter, thinner cone that can move rapidly and has a firmer suspension to repress movement at lower frequencies.
•A typical coaxial car speaker consists of both a woofer and a tweeter and is connected to the car stereo by positive and negative wires, though a common ground is sometimes used as well.

Tweeter Audio on wiseGEEK:

•A tweeter loudspeaker is used for high-frequency sounds, typically those sounds used to repel animals or to produce high-frequency noises in songs, movies and other audio. There are many tweeter speakers, such as the cone speaker, which has a small and fast cone and looks like a woofer.
•The faster the crystal and the diaphragm oscillate, the higher the pitch of the sound. A piezoelectric tweeter is not found in every audio setup,. Some basic sound systems simply rely one a medium sized speaker to create vibrations on a general range of frequencies.
