Hot sell headsets with high quality sound
Hi-Fi folding headset with FM radio
2014 bluetooth Headset for new style
Bending test: auricular wire, weight 200g, angle of +90 degrees, the number of 40 minutes, the standard value of 3000; plugs and wires, weight 200g, angle of +90 degrees, the number of 40 minutes, the standard is 5000.
Pull test: wire done 14.7N (1.5kg) Tam force for 60 seconds; wire can not be pulled off, it can not have electrical aspects; single line the Tam force less than 10N (1kg) is not greater than 29.4N (3 kg) of the test specifications.
Vibration: vibration frequency: 200HZ; vibration time: 6 hours; X, Y, Z axis vibration 2 hours; with packing, random vibration vibration test appearance and poor electrical properties;
Drop Test: drop height 1m; fall way around ,up and down the six-sided drop test poor electrical properties and structure.
Speaker life test: Test voltage: 0.4V (reference value), the sweep range: 20 ~ 20KHz test cycle: continuous 72H; the uninterrupted test no abnormal sound 72H;
Constant temperature and humidity test: Humidity: 65 ~ 85%, Low Temperature: -45 ° C Test time: the low temperature 48H, after completion of the test at room temperature humidity air-dried test structure and electrical properties of non-performing
