Some decoding functions make it more favored by consumers, and because of this, it has become the decoding king in the audio empire. At present, many speaker brands produce computer speakers. In addition to portable speakers, many multimedia 2.1 speakers now also have the function of reading cards.

Structure and composition

Computer speakers are mainly composed of speakers, cavity, and power amplifier.

speaker

The speaker (speaker unit) is the weakest device in the computer speaker equipment, and it is the most important for the computer speaker effect.

components. The speakers of computer speakers are mostly electric speakers, which use the interaction force between the voice coil and the constant magnetic field to make the diaphragm vibrate and produce sound.

cavity

The cavity is used to eliminate the acoustic short circuit of the speaker unit, suppress its acoustic resonance, widen its frequency response range and reduce distortion. The reason why the computer speaker has a cavity is mainly to prevent the sound wave signals on the front and back of the speaker diaphragm from directly forming a loop, so that only the high-frequency sound with a small wavelength can be transmitted, and other sound signals are superimposed and canceled. Lost.

Amplifier

The power amplifier is mainly composed of passive components such as inductors, resistors, capacitors and other passive components to form a filter network, and the audio signals of each frequency band are sent to the corresponding frequency bands respectively.
