Composition Of Speakers

- Jan 07, 2020-

The loudspeaker is a kind of energy conversion device that converts electrical signals into acoustic signals. The performance of the loudspeaker has a great impact on the sound quality. The speaker is the weakest component in audio equipment, and it is also the most important component for sound effects. There are many types of speakers, and prices vary widely. Audio power generates sound by 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 because their cabinets are thin and unable to overcome resonance (there are some well-designed plastic speakers that are far better than poor-quality wooden speakers); wooden speakers reduce the sound coloration caused by the resonance of the cabinet. Sound quality is generally better than plastic speakers.

Multimedia speakers are usually two-unit two-way design. One smaller speaker is responsible for the output of the middle and high frequencies, while the other larger speaker is responsible for the output of the middle and low frequencies.

When selecting speakers, the materials of these two speakers should be considered: the tweeter of the multimedia active speaker is mainly a soft dome (in addition, there is a titanium film dome for analog sound sources, etc.), which can reduce high frequencies in conjunction with digital sound sources The rigidity of the signal gives a gentle, smooth and delicate feeling. Multimedia speakers are now dominated by soft domes such as better quality silk films and lower cost PV films.

The woofer determines the characteristics of the sound of the speaker. It is relatively important to choose. The most common are the following: paper basins, but also glued paper basins, paper-based wool basins, and compacted basins.
