Digital Speaker RB-4028008G-06R-Z3
The RB-4028008G-06R-Z3 is a digital speaker with dimensions of Φ40.028.311.5mm and a weight of 13g. It features Nd-Fe-B magnet material with a size of Φ12.5×1.5T. The impedance is 8 ± 15% Ohm at 1000Hz, with a normal power rating of 2.0W and a maximum power rating of 2.5W. The frequency output (FO) ranges from 450±20% Hz, delivering a sound pressure level (SPL) of 94±3dB across a frequency range of 20-20KHZ. The distortion is capped at 10% maximum, and abnormal sound tests must be
conducted with 4.0 Volts sine wave for 505kHz. Polarity is indicated by the diaphragm moving forward when a positive DC is applied, with the red “+” or “Marked” terminal. It operates within a temperature range of -20 °C to +55 °C and can be stored between -25 °C to +65 °C. Load testing involves subjecting it to white noise for 96 hours at 2.0W input power, while high and low-temperature tests are conducted at +55±2 °C and -25±2 °C respectively, each lasting 96 hours. A humiditytest is also performed at +40±2 °C with a relative humidity of 9095% for 96 hours. Vibration tests are conducted with a frequency of 30-15 Hz and an amplitude of 1.5 mm for 2 hours per axis (x, y, z axis), while drop tests involve a 1 M free fall on a concrete floor repeated 10 times. Additionally, it undergoes a temperature cycle test at 25 + 65 °C for 5 cycles.
