Digital Speaker RB-17008G-18R
The RB-17008G-18R digital speaker is engineered to provide exceptional audio performance in a compact and lightweight design, making it ideal for various digital applications. With dimensions of Φ17.0*4.1mm and weighing just 1.6g, it offers versatility and efficiency without compromising on quality.
Constructed with Nd-Fe-B magnet material and featuring a magnet size of Φ8.0×1.2T, this speaker offers a nominal impedance of 8 ± 15% Ohm at 1000Hz when supplied with 1V input voltage. It has a
power rating of 1.0W under normal conditions, with a maximum power handling capability of 1.5W, ensuring reliable and consistent performance.
The speaker produces a fundamental output (FO) frequency of 900±20% Hz, achieving a sound pressure level (SPL) of 97±3dB across a wide frequency range of 20-20KHZ. Distortion is limited to a maximum of 10%, ensuring clear and accurate sound reproduction.
During abnormal sound tests, the speaker undergoes testing with a sine wave ranging from 50~5kHz at2.83 Volts to ensure proper operation. The diaphragm moves forward when a positive DC is applied to the red “+” or “Marked” terminal, ensuring correct polarity.
Operating within a temperature range of -40°C to +85°C, the speaker remains functional and reliable even in extreme temperature conditions, with a storage temperature range also spanning from -40°C to +85°C. It undergoes load testing, including exposure to white noise for 96 hours at 1.0W input power.
The speaker issubjected to high and low-temperature tests at +85±2°C and -40±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 Hz with 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 75 cm free fall on a concrete floor, repeated 10 timesto evaluate its durability under impact.
Finally, a temperature cycle test is conducted at 40 + 85°C for 5 cycles to ensure its performance under extreme temperature conditions, making it suitable for use in various environments and demanding applications.
