A speaker is a transducer device that converts electrical signals into acoustic signals. The performance of the speaker has a great influence on the sound quality. The speaker is the weakest component in the audio equipment, and it is the most important component for the sound effect. There are many types of speakers, and they vary widely in price. Audio electrical energy produces sound through electromagnetic, piezoelectric or electrostatic effects that cause its cone or diaphragm to vibrate and resonate (resonate) with the surrounding air. Low-grade plastic speakers have no sound quality due to their thin box body and cannot overcome resonance (some designed plastic speakers are far better than inferior wooden speakers); wooden speakers reduce the sound coloration caused by box resonance, Sound quality is generally better than plastic speakers. The loudspeaker size is naturally the bigger the better. Large-diameter woofers can have better performance in the low-frequency part, which can be selected in the purchase. Cabinets built with high-performance speakers mean lower transient distortion and better sound quality. The horns of ordinary multimedia speakers are mostly between 3 and 5 inches. Cabinets built with high-performance speakers also mean lower transient distortion and better sound quality. The speaker has two binding posts (two leads). When a single speaker is used, the two pins are not divided into positive and negative polarities. When multiple speakers are used at the same time, the two pins have polarities.
