Digital Speaker RB-3516008G-20R-A
The RB-3516008G-20R-A is a digital speaker featuring dimensions of 35.0*16.0*5mm and weighing 2.7g. It is constructed with Nd-Fe-B magnet material and has a magnet size of Φ8.0×1.2T. The speaker has an impedance of 8 ± 15% Ohm at 2000Hz with a normal power rating of 1.0W and a maximum power rating of 2.0W. Operating at a frequency output (FO) of 750±20% Hz, it produces a sound pressure level (SPL) of 95±3dB across a frequency range of 400~20KHZ. Distortion is limited to a maximum of 10%.
Abnormal sound tests are conducted using 2.83 Volts sine wave for 50~5kHz, with polarity indicated by the diaphragm moving forward when a positive DC is applied to the red “+” or “Marked” terminal. The speaker is designed to operate within a temperature range of -25°C to +65°C and can be stored under the same conditions. Load testing involves subjecting it to white noise for 96 hours at 1.0W input power, with high and low-temperature tests conducted at +55±2°C and -25±2°Crespectively, each lasting 96 hours. A humidity test is performed at +40±2°C with a relative humidity of 90~95% for 96 hours. Vibration tests are conducted at a frequency of 30-15 Hz with an amplitude of 1.5 mm for 2 hours per axis (x, y, z axis), while drop tests involve a 75 CM free fall on a concrete floor, repeated 10 times. Additionally, the speaker undergoes a temperature cycle test at 25 + 65°C for 5 cycles to ensure its durability and reliability under varying temperature conditions.
