Digital Speaker RB-23008F-101AR-Z1
The RB-23008F-101AR-Z1 digital speaker is designed to deliver high-quality audio output in a compact and lightweight package, making it suitable for various digital applications. With dimensions of Φ23.0*5.0mm and weighing only 3.5g, it offers a balance of performance and portability.
Constructed with Nd-Fe-B magnet material and featuring a Φ8.0×1.2T magnet size, this speaker provides an impedance of 8 ± 15% Ohm at 2000Hz when supplied with 1V input voltage. It has a nominal power rating of
1.0W, with a maximum power handling capability of 1.5W, ensuring reliable and consistent performance under normal operating conditions.
The speaker generates a fundamental output (FO) frequency of 750±20% Hz, producing a sound pressure level (SPL) of 96±3dB across a wide frequency range of 400-20KHZ. Distortion is limited to a maximum of 10%, ensuring clear and accurate sound reproduction.
During abnormal sound tests, the speaker is subjected to a 2.83 Volts sine wave for 50~5kHz, with thediaphragm moving forward when a positive DC is applied to the red “+” or “Marked” terminal, ensuring correct polarity.
Operating within a temperature range of -25°C to +65°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 1.0W input power.
The speaker is subjected to high and low-temperature tests at +65±2°C and -25±2°C, respectively, eachlasting 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 5 cycles to ensure its performance under extreme temperature conditions, making it suitable for use in various environments and demanding applications.
