1.1 Except other specified, measuring are under Temperature 15~35℃ R.H. 25 ~75% 1.2. Judgement condition Temperature 20 ±2 R.H. 63~67% 1.3 .Product shelf life is valid for 12 months only. 2. Output Sound Pressure Level (S.P.L.) and distortion testing setup 3. Environment & Mechanical test: 3.1 High Temperature: GB2423.
3.4 Humidity: GB5170.18-87 After exposure the speaker in the + 40±2 °C, relative humidity 90% ∼ 95% chamber for 48 hours, then leave the speaker at room temperature for 6 hours, the SPL should not deviate by ±3 db, and resonant frequency should not deviate by ±50 Hz, compare with pre-test measurement. 3.5 Vibration: GB11606.8-89 Frequency 30±15 Hz, Amplitude 1.5 mm for 3 Hours. After test, SPL shall not deviate by ±3 db from pre-test measurement, 3.
in rated frequency range, but the speaker wouldn’t be damaged heartily or mechanically. The persist time of the voltage is 1 hour. 5.2 The rated sine power. The rated sine power is corresponding with the rated sine voltage, its definition is Us2/R, Us indicates the maximum sin voltage, R indicates the rated impedance. 5.3 The rated noise power.
