Simple Explanation

A small speaker that produces high-pitched sounds using a soft, dome-shaped part that vibrates to make sound.

Concise Technical Definition

A high-frequency driver that uses a dome-shaped diaphragm—typically made from soft fabric, silk, or metal—to reproduce treble frequencies above ~2 kHz.

Layman-Friendly Analogy

Like a tiny, shallow bowl that vibrates quickly to make crisp, clear treble—such as cymbals or bird sounds in music.

Industry Usage Summary

Dome tweeters are the most common type of high-frequency driver in home and studio loudspeakers. Soft dome tweeters offer smooth sound, while metal domes provide more detail and efficiency. Common in 2-way and 3-way speaker systems.

Engineering Shortcut

Soft or metal high-frequency driver with dome-shaped diaphragm.

Full Technical Explanation

A dome tweeter is a type of high-frequency transducer used in loudspeakers to reproduce upper-range audio, typically from 2 kHz to 20 kHz. It features a dome-shaped diaphragm mounted in front of a voice coil. This shape provides wide dispersion and low distortion, making dome tweeters ideal for creating a smooth, broad soundstage. Materials vary—fabric domes (like silk) are known for smooth, non-fatiguing sound, while metal domes (like aluminum or titanium) offer increased detail and output. Dome tweeters are widely used in consumer and professional audio speakers due to their balance of performance, size, and cost.
