Digital Speaker RB-16008G-090CR
The RB-16008G-090CR digital speaker is a compact yet powerful audio solution designed for various digital applications where space and weight are critical factors. With its small dimensions of Φ16*4.1mm and lightweight design weighing only 1.8g, it offers excellent portability and versatility without compromising on performance.
Crafted 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 1000Hz when supplied
with 1V input voltage. It boasts a power rating of 1.0W under normal conditions, with a maximum power handling capability of 1.2W, ensuring reliable and consistent audio output.
The speaker delivers a fundamental output (FO) frequency of 900±20% Hz, achieving a sound pressure level (SPL) of 94±3dB across a broad 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 rigoroustesting with a sine wave ranging from 50~5kHz at 2.83 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 -25°C to +65°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 to white noise for 96 hours at 1.0W input power. Additionally, it endures high-temperature tests at +70±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 testwhere it is subjected to 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.
