[0002] Car audio is a sound recording and playback device set up to relieve the boring feeling of drivers and passengers during travel. The earliest use was car AM radios, and later AM FM radios, tape players, and developed to CD players and compatible with DCC, DAT digital audio, now the car audio has reached a high standard in terms of timbre, operation and anti-vibration. If you often drive on uneven roads, the long-term vibration will cause the voice coil to be skewed and affect the divergence of its sound. Even the excessive vibration of the door closing will cause the sound installation to loosen and vibrate continuously, affecting its sound effect

Abstract
The invention discloses an anti-vibration car stereo, the structure of which comprises a mounting head, a dust cover, an anti-vibration system, a paper cone, a collar, an outer shell, a limit metal sheet, a bottom ring, a limit ring, a connecting pipe, and an anti-vibration The dust cover is installed in the middle of the paper cone through the installation head, the bottom of the paper cone is installed with a collar, and the bottom of the collar is installed with a bottom ring. The invention is equipped with a clamping mechanism, an eccentric starting mechanism, an air floating system, a positive position structure, Height correction system, when the voice coil is skewed, it will affect the position of the paper cone to shift, thereby starting the eccentric starting mechanism, and under the transmission of the linkage structure, the air floating system will move to push the second magnet upwards, and the installation will be made according to the principle of same-sex repulsion. The voice coil with the first magnet moves up to adjust the height of the voice coil. At the same time, under the action of the linkage structure, the clamping mechanism will clamp the voice coil to correct its horizontal balance. The horizontal balance and height are corrected. Vibration in the process of driving the car will not affect its sound quality.
