Background

The loudspeaker is a transducer for converting electric signal into sound signal, and its performance has great influence on sound quality. The loudspeaker is the weakest component in the audio equipment, and is the most important component for the audio effect. Loudspeakers are of a wide variety and vary widely in price. The audio frequency electric energy makes the cone or diaphragm vibrate and generate resonance with the surrounding air to make sound through electromagnetic, piezoelectric or electrostatic effect. The low-grade plastic sound box cannot overcome resonance due to the fact that the box body is thin, and has no tone quality (a part of designed plastic sound boxes are far better than inferior wood sound boxes); the wooden sound box reduces the sound pollution caused by the resonance of the box body, and the sound quality is generally better than that of the plastic sound box. Generally, multimedia speakers are designed in a two-unit two-frequency-division mode, wherein one smaller speaker is responsible for the output of middle and high tones, and the other larger speaker is responsible for the output of middle and low tones.
