Everyone knows the sound principle of HIFI speakers: the audio signal input voice coil in the magnetic field vibrates violently, the vibration of the voice coil drives the sound bowl vibration forcing the air to vibrate sound. It can be seen that the sound basin plays an important role in the speaker generation system.
According to the classification of sound basin material can be basically divided into: paper basin, bulletproof cloth basin, wool basin, metal basin, ceramic basin and PP basin. Material of different, resulting in the occurrence of the characteristics of the speaker is not the same, the following one brief introduction.
Paper basin: paper basin is easy to fuse with other materials, so there are gumming paper basin, paper basin and so on. Although the paper basin cost is low, but its timbre performance is good, high sensitivity. So the paper basin is the most widely used.
Bulletproof cloth basin: Bulletproof cloth basin has a wide range of loudspeakers, suitable for music lovers who like strong bass. But it is expensive and difficult to make.
Wool basin: using wool as sound basin, with good flexibility, good at expressing light music.
Metal basin: add aluminum, magnesium and other metal elements, strong rigidity. HIFI speaker instantaneous explosive force is strong, suitable for dynamic music.
Ceramic basin: good at expressing human voice, classical music, exquisite timbre, good dynamic performance.
PP basin: polypropylene basin low distortion, good at performing a variety of music, high cost
In a variety of HIFI speakers alto basin is generally designed into a cone, there are also plate type, is to be determined according to the design of the speaker!
