Digital Speaker RB-2415008G-062MR-C1
The RB-2415008G-062MR-C1 digital speaker is a compact and lightweight audio device designed for various applications. With dimensions of Φ24.0*15.1*0.85mm and weighing 3.0 grams, it offers a compact form factor suitable for integration into a wide range of electronic devices.
Constructed with Nd-Fe-B magnet material, the speaker features a unique magnet size of 14.3×中孔9.4×1.15HΦ8.0×1.2T, providing an impedance of 8 ± 15% Ohm at 2000Hz when supplied with 1V. It has a power rating of
1.0W (normal) and 1.2W (maximum), ensuring sufficient audio output for its size.
The speaker operates within a frequency output (FO) range of 1200±20% Hz, delivering a sound pressure level (SPL) of 97±3dB across a frequency range of 20-20KHZ. Distortion is limited to a maximum of 10%, ensuring accurate and clear sound reproduction.
Abnormal sound tests involve subjecting the speaker to a 2.83 Volts sine wave for 50~5kHz, with the diaphragm moving forward when a positive DC is applied to thered “+” or “Marked” terminal, ensuring proper polarity.
The speaker is designed to operate within a temperature range of -20°C to +55°C and can be stored within the range of -25°C to +65°C without affecting its performance. Load testing includes exposure to white noise for 96 hours at 1.0W input power and pink noise for 24 hours at the same power level.
It undergoes high and low-temperature tests at +65±2°C and -25±2°C, each lasting 96 hours, along with a humidity test at+40±2°C with a relative humidity of 90~95% for 96 hours.
Vibration tests involve subjecting the speaker to a frequency of 30±15 Hz with an amplitude of 1.5 mm for 2 hours per axis (x, y, z axis) to assess its resilience to vibrations. Additionally, it undergoes a drop test where it is subjected to a 1 M free fall on a concrete floor, repeated 10 times to evaluate its durability under impact.
Finally, a temperature cycle test is conducted at 25 + 65°C for 5 cycles to ensure its performanceunder varying temperature conditions, making it suitable for a wide range of environments and applications.
