Role of speaker accessories

1.vibration system
Voice coil: the voice coil is the heart of the speaker, the voice coil is electrified in the magnetic field The voice coil is electrified and moves up and down in the magnetic field under the action of force.

Diaphragm: commonly known as the drum paper, the voice coil to promote its up and down reciprocating movement, thus Push the air, and the atmospheric pressure to produce a difference, push the eardrum so that the human ear to hear the sound. Convert mechanical energy into sound energy.

Dust cap: prevents dust from entering the magnetic gap. At the same time, it can improve themiddle and high frequencies of the loudspeaker can be improved.

Damper (positioning spine) always keep the voice coil in the magnetic gap to do vertical up and down movement, but also can adjust the resonance frequency of the speaker.

2.Support system
Frame: plays the role of supporting the vibration system, which is used to support the diaphragm, the spring wave, and provide the terminal board. It is used to support the diaphragm, bounce the wave, and provide a fixing point for the terminal board.

Terminal board: Mainly connects the wire with the access point of external signals.

Wire: connects the voice coil with the terminal board, and serves as an input for external electrical signals.
