Soundbar Speaker RB-B18004G-012AR

The RB-B18004G-012AR is a high-performance soundbox speaker engineered to deliver immersive audio experiences across various electronic devices. With dimensions of Φ69*18*19mm and a weight of 18.7g, it offers a compact and lightweight design suitable for integration into a wide range of applications.

Constructed with Nd-Fe-B magnet material, the RB-B18004G-012AR features a magnet size of 11.0×2.0, ensuring efficient and reliable performance with a nominal impedance of 4 ± 15% Ohm at 2000Hz

and 1V input. This makes it compatible with a broad array of audio devices, ensuring seamless integration into different systems.

With a power rating of 2.0W (normal) and 2.5W (maximum), this speaker delivers robust sound output with a frequency range of 850±20% Hz and a sound pressure level (SPL) of 87±3dB, covering the entire audible spectrum from 20Hz to 20KHz with clarity and precision.

To ensure consistent performance and reliability, the RB-B18004G-012AR undergoes rigorous testingprocedures. It must pass a normal test using a 2.83V sine wave across a frequency range of 50~5kHz, and its polarity is 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 -20°C to +55°C and can be safely stored in temperatures from -25°C to +65°C. It undergoes 96 hours of exposure to white noise at 2W input power to ensure durability andresilience.

Furthermore, the RB-B18004G-012AR undergoes extensive 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 16 times.

To assess its performance under varying temperature conditions, the RB-B18004G-012AR is subjected to temperature cycling tests, enduring 5 cycles from 25°C to +65°C. This ensures that it remains reliable and functional evenin extreme temperature fluctuations.

With its durable construction, comprehensive testing, and powerful audio performance, the RB-B18004G-012AR is an ideal choice for soundbox applications in a variety of electronic devices, delivering rich and immersive sound with reliability and precision.
