Tweeter facts for kids
A tweeter is a special kind of loudspeaker. It's usually small and its main job is to make high-pitched sounds. Think of the sound a whistle makes, or the chirping of a bird. These are the kinds of sounds a tweeter is designed to play.
Sounds have something called frequency. This is how high or low a sound is. Tweeters are made for very high frequencies, up to 20,000 Hz. Humans can't hear sounds higher than 20,000 Hz. If you tried to play very low sounds, like the rumble of thunder, through a small tweeter, it could damage it. That's because tweeters aren't built to make big movements. For those deep, low sounds, you need a different kind of speaker called a subwoofer.

What is a Tweeter?
A tweeter is a small speaker that focuses on the highest sounds in music or speech. It's part of a bigger speaker system. Just like different instruments play different notes, different speakers play different sound frequencies.
Why Do We Need Tweeters?
Our ears can hear a wide range of sounds, from very low rumbles to very high squeaks. No single speaker can play all these sounds perfectly. That's why speaker systems often have different types of speakers working together.
Tweeters handle the high notes, making them clear and crisp. Without a tweeter, high sounds might sound muffled or unclear. This helps you hear details like the shimmer of cymbals or the high notes of a singer.
How Tweeters Work
Tweeters work by vibrating a small, light cone or dome very quickly. This fast movement creates the high-frequency sound waves that travel to your ears. Because high-frequency sounds have short wavelengths, tweeters don't need to move much to create them.
Different Types of Tweeters
There are several ways tweeters are made, each with its own benefits:
- Dome Tweeters: These are very common. They have a dome-shaped part, often made from silk, fabric, or metal. They give a wide sound.
- Cone Tweeters: These look like tiny versions of bigger speakers. They have a cone shape and are often found in older or less expensive speakers.
- Ribbon Tweeters: These use a very thin, flat ribbon that vibrates. They can produce very clear and detailed high sounds.
- Electrostatic Tweeters: These use an electric field to move a thin film. They are known for being very accurate and clear.
