Digital Speaker RB-2030008G-059AR
The RB-2030008G-059AR digital speaker is a compact audio solution designed for various electronic applications. With dimensions of Φ30.0*19.4*6.7mm and weighing just 3.0 grams, it offers a lightweight and space-efficient design.
Constructed with Nd-Fe-B magnet material, the speaker features a unique magnet size of Φ14.2×7.2×1.5T, providing an impedance of 8 ± 15% Ohm at 1000Hz when supplied with 1V. It has a power rating of 0.1W (normal) and 0.2W (maximum), making it suitable for low-power
applications.
The speaker operates within a frequency output (FO) range of 400±30% Hz, delivering a sound pressure level (SPL) of 86±3dB across a frequency range of 20-20KHZ. Distortion is limited to a maximum of 10%, ensuring clear sound reproduction.
Abnormal sound tests involve subjecting the speaker to a 0.89 Volts sine wave for 50~5kHz, with the diaphragm moving forward when a positive DC is applied to the red “+” or “Marked” terminal, ensuring correct polarity.
The speaker isdesigned to operate within a temperature range of -25°C to +65°C and can be stored within the same range without affecting its performance. Load testing includes exposure to white noise for 96 hours at 0.1W 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.
Vibration tests involve subjecting the speaker to a frequency of 30±15 Hzwith 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 a wide range of environments and applications.
