Digital Speaker RB-15008G-116AR
The RB-15008G-116AR digital speaker is a compact and lightweight audio component designed for various digital applications where space and weight are critical considerations. With dimensions of Φ15.0*4.1mm and weighing only 1.4g, it offers excellent portability and versatility without compromising on performance.
Constructed with Nd-Fe-B magnet material and featuring a magnet size of 7.8∮×1.0 T, this speaker provides a nominal impedance of 8 ± 15% Ohm at 2000Hz when supplied with 1V input
voltage. It has a power rating of 0.5W under normal conditions, with a maximum power handling capability of 0.7W, ensuring reliable and consistent audio output.
The speaker delivers a fundamental output (FO) frequency of 1100±20% Hz, achieving a sound pressure level (SPL) of 93±3dB across a wide frequency range of 20-20KHZ. With distortion limited to a maximum of 10%, it offers clear and accurate sound reproduction.
During abnormal sound tests, the speaker undergoes rigorous testing with asine wave ranging from 50~5kHz at 2.0 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 extreme temperature conditions. It has a corresponding storage temperature range from -25°C to +65°C.
The speaker undergoes load testing, including exposure towhite noise for 96 hours at 0.5W 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 subjectedto a 1 M free fall on a concrete floor, repeated 10 times to assess its durability under impact.
Finally, a temperature cycle test is conducted at 25 + 65°C for 5 cycles to ensure its performance under extreme temperature conditions, making it suitable for use in various environments and demanding applications.
