Technical Field

The utility model relates to an on-vehicle loudspeaker technical field especially relates to on-vehicle loudspeaker stereo set with shock attenuation noise reduction effect.

Background

The loudspeaker is a modern electroacoustic component, the function is to convert the electrical signal into sound, also called loudspeaker, the loudspeaker is a kind of conversion equipment that the electrical energy is converted into sound, when different electronic energy is transmitted to the coil, the coil produces an energy and magnetic field interaction of the magnet, this interaction causes the paper disc to vibrate, because the electronic energy changes at any time, the coil of the loudspeaker will move forward or backward, so the paper disc of the loudspeaker will move, this movement makes the density degree of the air change and produce the sound, set up the movable iron chopping piece (armature) in the middle of a U-shaped magnet, when the current flows through the coil, the armature will be magnetized and the magnet produces the phenomenon of repulsion, and drive the vibrating diaphragm to move at the same time, this kind of design cost is cheap but not good in effect, so use on telephone receiver and small-sized earphone, the inductive loudspeaker is similar to the electromagnetic principle, however, the armature is doubled, and the two voice coils on the magnet are not symmetrical, and the two armatures move to push each other for different magnetic fluxes when the signal current passes through, unlike the electromagnetism, the inductance can reproduce lower frequency, but the efficiency is very low.
