Digital Speaker RB-2809008G-010AR
The RB-2809008G-010AR digital speaker is engineered for compact audio solutions, featuring a sleek design and reliable performance. With dimensions of 28×9x3.8mm and a weight of 2.4g, it offers a lightweight and space-saving solution for various applications.
Constructed with Nd-Fe-B magnet material and a magnet size of 11x3x1.5T, this speaker provides an impedance of 8 ± 15% Ohm at 2000Hz when supplied with 1.0V input voltage. It has a power rating of 0.8W under normal conditions, with a
maximum power handling capability of 1.0W, ensuring clear and consistent sound output.
The fundamental output (FO) frequency of the speaker is 860±20% Hz, accompanied by a sound pressure level (SPL) of 94±3dB across a frequency range of 20-20KHZ. With distortion limited to a maximum of 15%, it maintains audio fidelity even at higher volumes.
During abnormal sound tests, the speaker undergoes rigorous testing with a sine wave ranging from 50~5kHz at 2.53 Volts to ensure optimal performance.The diaphragm moves forward when a positive DC is applied to the red “+” or “Marked” terminal, ensuring correct polarity for proper operation.
Operating within a temperature range of -20°C to +55°C, the speaker remains functional and reliable even in varying temperature conditions. It has a corresponding storage temperature range from -25°C to +65°C, ensuring its longevity and performance over time.
The speaker undergoes load testing, including exposure to white noise for 96 hoursat 1.0W input power. Additionally, it endures high-temperature tests at +65±2°C and low-temperature tests at -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 evaluate its resilience to vibrations. Furthermore, it undergoes a drop test where it is subjected to a 1 M free fall on aconcrete floor, repeated 10 times to assess its durability under impact.
Additionally, the speaker must pass a temperature cycle test involving exposure to temperatures ranging from 25°C to +65°C, repeated for 5 cycles, to ensure its reliability under temperature variations. With its compact size and robust performance, the RB-2809008G-010AR digital speaker is an ideal choice for various audio applications.
