The speaker is a transducer

- Mar 16, 2019-

A speaker is a transducing device that converts an electrical signal into an acoustic signal. The performance of the speaker has a great influence on the sound quality. The speaker is one of the weakest devices in audio equipment, and it is one of the most important components for sound effects. There are many different types of speakers, and the prices vary greatly. Audio power passes through electromagnetic, piezoelectric or electrostatic effects, causing the cone or diaphragm to vibrate and resonate (resonate) with the surrounding air to produce sound.

Low-grade plastic speakers are thin and can't overcome resonance, and there is no sound quality (some partially designed plastic speakers are far better than inferior wooden speakers); wooden speakers reduce the sound of the box resonance. Sound quality is generally better than plastic speakers.

Usually multimedia speakers are dual-unit two-way design, one smaller speaker is responsible for the mid-highs output, and the other larger speaker is responsible for the mid-bass output.
