Digital Speaker RB-50008F-41R
The RB-50008F-41R digital speaker is a compact yet powerful audio component designed for digital applications where space is limited. With dimensions of Φ20.0*8.6mm and a weight of 13.8g, it offers a balance between size and performance, making it suitable for various electronic devices.
Constructed with Nd-Fe-B magnet material and featuring a magnet size of Φ12.5×1.5T, this speaker offers an impedance of 8 ± 15% Ohm at 1000Hz when provided with 1V input. Its power rating is impressive,
with a normal rating of 2.0W and a maximum rating of 2.5W, ensuring high-quality audio output even in demanding applications.
The speaker delivers an output frequency (FO) range of 370±20% Hz, producing an impressive sound pressure level (SPL) of 103±3dB across a frequency range of 20-20KHZ. Distortion is limited to a maximum of 10%, guaranteeing clear and accurate sound reproduction.
Abnormal sound tests involve subjecting the speaker to a 4.0 Volts sine wave for 50~5kHz, with the diaphragmmoving forward when a positive DC is applied to the red “+” or “Marked” terminal, confirming correct polarity.
Operating within a temperature range of -20°C to +50°C, the speaker can be stored within the range of -25°C to +55°C without compromising its performance. 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 +55±2°C and -25±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 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 5cycles to ensure its performance under varying temperature conditions, making it suitable for use in diverse environments and applications.
