Audio refers to a set of audio system in which electrical equipment is combined to produce sound. The development history of audio technology can be divided into electronic tube, transistor, integrated circuit, field effect tube four stages, namely refers to a set of equipment that can restore playback audio signals.

Testing standard

Sound CE certification EMI (electromagnetic interference) can be divided into:
1. Radiation :(1) space Radiation (Chamber) (2) power Radiation Clamp) (3) Opensite test
This is the right value. 2. Conduction. Voltage Flicker
Sound CE certification EMS (electromagnetic tolerance) can be divided into:
1.ESD (electrostatic resistance test) 2.EFT (pulse resistance test) 3.SURGE (lightning resistance test) 4.RS (rf resistance test) 5.CS (rf resistance test) 6.MagneticField (power frequency resistance MagneticField test) 7. Resistance to low frequency electrical interference of AC power input 9. Resistance to continuous electrical interference of DC up to 150KHz audio C certified LVD safety: Power input test dangerous energy label durability test a capacitor discharge test current-limiting circuit test grounding resistance test wet processing test power supply cord stress relief test temperature impact test drop test ball pressure test working voltage, clearance and creepage distance test abnormal work test the electric strength test
