Tweeter speakers are audio drivers in a speaker system. They are a type of electromechanical loudspeaker that produces both sound and music at high frequencies. Hence, these devices create the upper range of a sound. Tweeter speakers are usually small. In addition, they produce short wave-length audio and have a tiny cone. Overall, they are an important addition to woofers.
The Mechanics of Tweeter Speakers
Almost all tweeter speakers are electrodynamic drivers and contain a voice coil suspended inside a magnetic field. These devices work by applying a current from the output of an amp circuit to a voice coil. In turn, the voice coil generates a magnetic field that works against the fixed magnetic field of the magnet. As a result, both the voice coil and the diaphragm move. This movement is similar to the waveform of the electronic signal supplied from the amplifier’s output to the voice coil. The vibration of the voice coil moves the diaphragm, which is what causes the air to move. With all these mechanics in progress, finally, air motions, audio waves, or high sounds emerge.
A Brief Piece of History
The first tweeter speakers were mostly like woofers. However, technology has taken over and modern versions of these speakers have evolved. Nowadays, hard-dome tweeters are of aluminium, a mixture of aluminium and magnesium, or titanium. In contrast, the materials of soft-dome tweeters are polyester film or a mixture of polyester fabric and polymer resin.
Tweeter Speakers: How They Work
Tweeters usually operate in collaboration with woofers, which produce low frequencies. Tweeter speakers aim to convert an electrical signal into a mechanical air movement. Similarly, they aim to provide adequate damping for the dome to stop when the signal ends. These devices ensure suspension linearity by allowing high output at the low end of its frequency range. Moreover, they also ensure magnetic freedom by permitting the dome to remain centered. All in all, they offer adequate power handling.
Some Variants
Super tweeters and novel egg tweeters involve a semi-independent unit. The novel egg tweeter capable of satisfying the user’s position and preference, so it plugs in and swings to adjust the sound field.
