Digital Speaker RB-2512008G-008AR
The RB-2512008G-008AR digital speaker is a compact and lightweight audio component designed for various applications. With dimensions of Φ25.0*12.0*3.7mm and weighing only 3.9 grams, it offers a balance of portability and performance.
Constructed with Nd-Fe-B magnet material and featuring a magnet size of Φ7.6×1.0T, this speaker provides an impedance of 8 ± 15% Ohm at 2000Hz when supplied with 1V. It has a power rating of 1.0W (normal) and 1.5W (maximum), ensuring adequate audio output for
its size.
The speaker operates within a frequency output (FO) range of 1200±20% Hz, producing a sound pressure level (SPL) of 93±3dB across a frequency range of 20-20KHZ. Distortion is limited to a maximum of 10%, ensuring clear and accurate sound reproduction.
Abnormal sound tests involve subjecting the speaker to a 2.83 Volts sine wave for 50~5kHz, with the diaphragm moving forward when a positive DC is applied to the red “+” or “Marked” terminal, ensuring correct polarity.
It isdesigned to withstand operating temperatures ranging from -25°C to +65°C and can be stored within the same temperature range without compromising performance. Load testing is performed by exposing the speaker to white noise for 96 hours at 1.0W input power.
High and low-temperature tests are conducted at +55±2°C and -25±2°C respectively, each lasting 96 hours, while a humidity test is carried out at +40±2°C with a relative humidity of 90~95% for 96 hours.
Vibration tests involvesubjecting 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 to ensure its performance under varying temperature conditions, making it suitable for a wide range ofenvironments and applications.
