Digital Speaker RB-45008F-054R
The RB-45008F-054R digital speaker is engineered to deliver exceptional audio performance in a compact form factor, making it ideal for various digital applications. With dimensions of Φ45.0*6.8mm and a weight of 13.3g, it strikes a balance between size and power.
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 robust, 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 450±20% Hz, producing an impressive sound pressure level (SPL) of 101±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 diaphragm moving forward when apositive DC is applied to the red “+” or “Marked” terminal, confirming correct polarity.
Operating within a temperature range of -20°C to +60°C, the speaker can be stored within the range of -25°C to +65°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 +65±2°C and -25±2°C, respectively, each lasting 96 hours, along with a humiditytest 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 itsperformance under varying temperature conditions, making it suitable for use in diverse environments and applications.
