Digital Speaker RB-2014008G-050AR
The RB-2014008G-050AR digital speaker is a compact and lightweight audio solution designed for various digital applications. With dimensions of 20×14x3.5mm and weighing only 1.4g, it offers a balance of size and performance suitable for portable devices.
Constructed with Nd-Fe-B magnet material and a magnet size of Φ9.5×1.2T, this speaker provides an impedance of 8 ± 15% Ohm at 2000Hz when supplied with 1.0V input voltage. It has a power rating of 1W under normal conditions, with a maximum
power handling capability of 1.3W, ensuring clear and crisp sound reproduction.
The fundamental output (FO) frequency of the speaker is 1180±20% Hz, accompanied by a sound pressure level (SPL) of 94±3dB across a wide frequency range of 20-20KHZ. With distortion limited to a maximum of 10%, it delivers distortion-free audio for an immersive listening experience.
During abnormal sound tests, the speaker undergoes rigorous testing with a sine wave ranging from 50~5kHz at 2.83 Volts to ensureoptimal 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 towhite noise for 96 hours at 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 subjectedto a 1 M free fall on a concrete 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. Overall, the RB-2014008G-050AR digital speaker offers reliable performance in a compact form factor, making it ideal for various digital audio applications.
