Test in anechoic room and use the IEC standard baffler which size at : 1350 mm (W) X 1650 mm (H) 2. Test should be made under the conditions of room temperature (20 ±10 °C), relative humidity (60 ±20%) and normal atmospheric pressure. In this case, however, that the judgment is questionable, the test conditions are to be changed to room temperature 20 ±2 °C, relative humidity 60~70% and normal atmospheric pressure.

Two directions: upper and side of the product are to be applied for this drop test once respectively. 5-7 Life test in the room temperature Input the signal with the valid frequency range on the speaker in continuously for 100 hours, the room temperature should control in 15 °C to 35 °C. Conduct the test for the directions of X Y and Z for 0.5 hour each 5-8 Vibration test Tone: no obviously noise SPL ±3dB F0 ±20% ACR ±15% (total 1.5 hours). To-and Fri sweep time(from 10 to 55 Hz and then 55 to 10) under single amplitude of 0.75 mm is 3 minute, then expose to the room temperature for 2 hours. NOTE: The frame is allowed to deform after drop test. 6. Electrical Testing Method： East Electronics 4/5 7.
