The classification of high, medium and woofer refers to the pitch of the horn sound. Because the horn is a physical device, each type has its own optimal working frequency because of different materials. In order to pursue a better sound restoration effect, the signal is artificially adjusted according to the tone Separately sent to the speakers made by the most suitable working frequency materials, conventionally divided into treble, midrange, woofer, of course, there are other classification methods.
Treble Speaker
Relatively speaking, the tweeter is working in a relatively sharp tone range, that is, a high operating frequency state, the high frequency direction is very strong, and the speaker can be clearly judged by turning the ear in one direction. The characteristic of the tweeter is to be able to produce sound by rapid vibration, but the vibration amplitude is usually relatively small. Therefore, such a loudspeaker generally uses a relatively thin and tough diaphragm, and the area, that is, the diameter is relatively small. When the tweeter is not sounding, the sound of the sound will be blurry and a bit boring, no longer transparent and clear.
Midrange Speaker
Relatively working in the range of moderate tones, it is the sound speaker of the main part of the sound. The midrange range is the main part of the human ear receiving sound information. Most of the sound content that can be distinguished is emitted by the midrange speaker. So the characteristic is that the vibration speed is moderate, but the vibration amplitude is relatively large. Because it bears the main sound content, the caliber is relatively large. Horn diaphragm materials are generally pressed with lightweight fiber paper or fiber non-woven fabric to reduce weight, and can withstand relatively large air pressure at an appropriate speed. If the midrange speaker does not sound, basically the sound content will lose most of the sound, the sound will be very small and the content cannot be heard clearly.
Subwoofer Speaker
Works in a very low-pitched range, but it is also the largest power-bearing speaker. Bass is the part with the largest amplitude of air vibration, and the tactile sensation can clearly feel the vibration of air. Therefore, its characteristic is that it has a sufficiently large vibration amplitude to push the air to generate a high field pressure (also called sound pressure). Because the vibration amplitude is too large, the vibration membrane is generally a combination of lightweight and high-strength fibers to ensure lightness and rigidity. The bass direction is very weak, and it is difficult for the human ear to distinguish the direction of the starting sound, so there is generally no requirement for the location of the independent bass speaker. But because of the strong enough field pressure, the bass can bring people dynamic. If the woofer does not sound, the sound sounds like an old record player and a small radio, and the bass drum sounds like knocking on the table, the sound is not full.
