Soundbar Speaker RB-28008G-034AR
The RB-28008G-034AR is a versatile soundbox speaker designed to deliver high-quality audio performance across a range of electronic devices. With dimensions of Φ100.0*45.0*20.5mm and a weight of 8g, it offers a compact and lightweight design suitable for various applications.
Constructed with Nd-Fe-B magnet material, the RB-28008G-034AR features a magnet size of Φ15.5×2.3T, ensuring efficient and reliable sound reproduction. It has a nominal impedance of 8 ± 15% Ohm at 1000Hz and 1V input,
making it compatible with a wide range of audio devices.
The speaker boasts a power rating of 1.0W (normal) and 1.5W (maximum), delivering powerful sound output with a frequency range of 280±20% Hz and a sound pressure level (SPL) of 94±3dB. This ensures clear and immersive audio reproduction across the entire audible spectrum from 20Hz to 20kHz.
To guarantee consistent performance and reliability, the RB-28008G-034AR undergoes rigorous testing procedures. It must pass a normal test using a2.83V sine wave across a frequency range of 50~5kHz, with polarity confirmed by observing diaphragm movement when applying a positive DC voltage to the red “+” or “Marked” terminal.
The speaker is designed to operate reliably in temperatures ranging from -25°C to +65°C and can be safely stored in temperatures from -25°C to +65°C. It undergoes 96 hours of exposure to white noise at 1.0W input power to ensure durability and resilience.
Additionally, the RB-28008G-034AR undergoesextensive durability testing, including vibration testing at a frequency of 30±15 Hz and an amplitude of 1.5 mm for 2 hours per axis (x, y, z), as well as a drop test of 1M onto a concrete floor, repeated 17 times.
To assess its performance under varying temperature conditions, the RB-28008G-034AR is subjected to temperature cycling tests, enduring 5 cycles from 25°C to +65°C. This ensures that it remains reliable and functional even in extreme temperature fluctuations.
With its durableconstruction, comprehensive testing, and powerful audio performance, the RB-28008G-034AR is an ideal choice for soundbox applications in various electronic devices, providing clear and immersive sound reproduction with reliability and precision.
