The speaker is a kind of electrical energy into sound a conversion equipment, when different electron energy to coil, coil produces a kind of energy with magnet magnetic field interaction, paper plates, vibration caused by the interaction because the electron energy at any time change, loudspeaker coil will forward or backward movement, so the speaker paper plates will follow sports, these actions make the air resulting from the change in terms of sound. Lead the trend of The Times with the latest technology, the latest equipment, in the hundred million macro principle and PCBA circuit, combined with the speaker amplifiers operation design rich voice, strong sense of quality and soft quality dynamic speaker got recognition from all walks of life.
