Digital Speaker RB-30008F-121R
The RB-30008F-121R digital speaker is engineered to deliver exceptional audio performance in a compact form factor, making it ideal for various digital applications. With dimensions of Φ30.0*5.4mm and weighing 6.6g, it strikes a balance between size and weight, ensuring versatility and portability.
Featuring Nd-Fe-B magnet material and a Φ9.5×1.5T magnet size, this speaker offers an impedance of 8 ± 15% Ohm at 1500Hz when supplied with 1V input. It has a robust power rating of 2.0W under
normal conditions, with a maximum power handling capability of 2.5W, ensuring reliable and consistent performance.
The speaker produces a fundamental output (FO) frequency of 750±20% Hz, generating a sound pressure level (SPL) of 96±3dB across a frequency range of 20-20KHZ. Distortion is limited to a maximum of 10%, guaranteeing clear and accurate sound reproduction.
During abnormal sound tests, the speaker is subjected to a 4.0 Volts sine wave for 50~5kHz, with the diaphragm moving forwardwhen a positive DC is applied to the red “+” or “Marked” terminal, ensuring correct polarity.
Operating within a temperature range of -20°C to +55°C, the speaker remains operational and reliable, with a storage temperature range spanning from -25°C to +65°C. It undergoes load testing, including exposure to white noise for 96 hours at 2.0W input power.
The speaker is subjected to high and low-temperature tests at +65±2°C and -25±2°C, respectively, each lasting 96 hours, alongwith 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 1 M free fall on a concrete floor, repeated 10 times to evaluate its durability under impact.
Finally, a temperature cycle test is conducted at 25 + 65°C for 5 cycles toensure its performance under extreme temperature conditions, making it suitable for use in various environments and demanding applications.
