Digital Speaker RB-3010008G-004AR
The RB-3010008G-004AR digital speaker is characterized by its compact dimensions of Φ14.8*7.8*4.8mm and lightweight design, weighing 3.1g. Constructed with Nd-Fe-B magnet material, it features a magnet size of 10.4×3.4×1.5T. Operating with an impedance of 8 ± 15% Ohm at 2000Hz and a power rating of 1.0W normal and 1.2W maximum, this speaker delivers a frequency output (FO) of 970±20% Hz and achieves a sound pressure level (SPL) of 92±3dB over a frequency range of 20-20KHZ. Distortion is
limited to a maximum of 10%. Abnormal sound tests are conducted using 2.83 Volts sine wave for 50~5kHz, with the diaphragm moving forward when a positive DC is applied to the red “+” or “Marked” terminal, indicating correct polarity.
The speaker is designed to operate within a temperature range of -20°C to +55°C and can be stored within a broader range of -25°C to +65°C. Load testing involves subjecting it to white noise for 96 hours at 1.0W input power, with subsequent high andlow-temperature tests conducted at +65±2°C and -25±2°C respectively, 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), ensuring its resilience to vibrations. Drop tests involve subjecting the speaker to a 1 M free fall on a concrete floor, repeated 10 times to assess its durability under impact.Additionally, the speaker undergoes a temperature cycle test at 25 + 65°C for 5 cycles to ensure its performance under varying temperature conditions.
