Midsize Soundbox RB-52LPU04K

The RB-52LPU04K soundbox speaker is designed with a dimension of 52x52x30mm and weighs 34g. It utilizes a ferrite magnet material with a size of Φ50×8.0T and operates at an impedance of 4 ± 15% Ohm at 1000Hz with 1V input. The speaker has a power rating of 3W under normal conditions, with a maximum rating of 3.5W. It features a fundamental frequency (FO) of 110±20% Hz and delivers a sound pressure level (SPL) of 95±3dB, covering a frequency range from F0 to 20,000Hz while maintaining

distortion below 5%.

During abnormal sound tests, the speaker must perform normally when subjected to 6.32 volts sine wave. The polarity is marked by a red “+” or “Marked” terminal, and the diaphragm moves forward when a positive DC is applied. Operating temperature ranges from -20°C to +55°C, with storage temperature ranging from -25°C to +65°C. The speaker undergoes various durability tests, including a load test with white noise for 96 hours at 2.0W input power, ahigh-temperature test at +65±2°C for 96 hours, a low-temperature test at -25±2°C for 96 hours, and a humidity test at +40±2°C with 90~95% relative humidity for 96 hours. Additionally, it undergoes a vibration test at a frequency of 30±15 Hz with an amplitude of 1.5 mm for 2 hours per axis (x, y, z-axis), a drop test of 1 meter free falling on a concrete floor 19 times, and a temperature cycle test ranging from 25°C to 65°C over 5 cycles.

The RB-52LPU04K soundbox speaker has a minimumorder quantity (MOQ) of 10,000 units.
