Basic knowledge of speaker

Changzhou Su Yang speakers to drive air sound. The most commonly used system in the automotive audio and video system is the electric loudspeaker system, which works in the work principle of the system. The speaker is a device that can convert audio signals into sound (sound). Due to the limitations of the physical characteristics of the speaker's voice, the current technology is still unable to make Dan Zhenmo's full band speakers more perfect reproduction of the audio range. So, the speakers of different frequency bands are designed, which can obtain the best replay characteristics in different frequency bands. The quality of the whole frequency band after synthesis can reach the ideal level.
is here to illustrate that the speakers here refers to the speaker, while the speaker and the box body to form a speaker system, which is composed of the unit plus box (front sound field is the unit plus the door) is composed of a speaker system. This also shows that a single speaker due to the sound of the sound of the basin before and after a short circuit, will not produce an accurate sound.
speakers can be classified into different categories according to different classification methods:
　　According to the band reduction to divide: tweeter, midrange speaker, bass speaker, woofer;
　　According to the trumpet caliber to points: 3/4, 1, 3, 51/4, 6.5, 8, 10, 15, 18, 12, etc., in the car audio 5X7, 6X9, 4X6, etc..
　　According to the combination method can also be divided into: coaxial speakers and speakers, etc.. < br / > woofers and subwoofers in general are cone vibration loudspeaker, and Alto or tenor horns of vibrating plate with cone type also has global roof type. Although there are many types of vibrating plate, but many of the principles of the speakers are interlinked, as follows: the higher the frequency of
, the speed of vibration plate movement should be faster, therefore, the higher the frequency, the smaller the vibration plate is better. The smaller the
vibration plate, the smaller the air movement, the smaller the sound pressure output. The higher the
frequency, the stronger the directivity, so the high frequency of the high frequency of the speaker is more broad. The quality of the
vibrating plate or the top of the ball can also be explained by the speed of its vibration, the lighter the mass, the faster the vibration velocity, the more accurate the transient response is. The lighter the quality of the
diaphragm film, the more prone to the distortion of the segmentation vibration when the loud pressure is out.
voice coil, the greater the power to bear. The smaller the voice coil, the better the transient response.
