Digital Speaker RB-2030008G-046MR-E
The RB-2030008G-046MR-E digital speaker is a versatile audio component engineered for various electronic applications. Its compact dimensions of Φ30.0*20.0*4.8mm and lightweight design, weighing just 3.0 grams, make it suitable for integration into small electronic devices.
Constructed with Nd-Fe-B magnet material, featuring a unique magnet size of Φ11.5×1.5T, this speaker offers an impedance of 8 ± 15% Ohm at 1000Hz when supplied with 1V. It has a power rating of 1.0W (normal) and 1.5W
(maximum), enabling reliable performance in low to moderate-power applications.
The speaker operates within a frequency output (FO) range of 670±20% Hz, delivering a sound pressure level (SPL) of 96±3dB across a frequency range of 20-20KHZ. With a distortion limited to a maximum of 10%, it ensures clear and accurate 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 tothe red “+” or “Marked” terminal, ensuring correct polarity.
Operating within a temperature range of -20°C to +55°C, the speaker can be stored within the same range without affecting its performance. Load testing includes exposure to white noise for 96 hours at 1.0W input power.
It undergoes high and low-temperature tests at +65±2°C and -25±2°C, respectively, each lasting 96 hours, along with a humidity test at +40±2°C with a relative humidity of 90~95% for 96 hours.
Vibrationtests 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 performance under varying temperature conditions, making it suitable for use in awide range of environments and applications.
