Digital Speaker RB-3519008F-007R
The RB-3519008F-007R is a digital speaker with dimensions of Φ35.019.06.0mm and a weight of 5.6g. It utilizes Nd-Fe-B magnet material with a size of Φ11.0×1.2T. The speaker has an impedance of 8 ± 15% Ohm at 1000Hz with a normal power rating of 1.0W and a maximum power rating of 1.5W. Its frequency output (FO) ranges from 560±20% Hz, generating a sound pressure level (SPL) of 96±3dB over a frequency range of 20-20KHZ. Distortion is capped at 10% maximum, and abnormal sound tests must be
conducted with 2.83 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 -25°C to +65°C and can be stored between -25°C to +65°C. Load testing involves subjecting it to white noise for 96 hours at 1.0W input power, while high and low-temperature tests are conducted at +65±2 °C and -25±2 °C respectively, each lasting 96 hours. A humidity testis 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 75 CM free fall on a concrete floor, repeated 10 times. Additionally, it undergoes a temperature cycle test at 25 + 65°C for 5 cycles.
