Headset Speaker RB-40040G-03R
The RB-40040G-03R is a robust headset speaker engineered to deliver high-quality audio performance across a wide range of applications. With a diameter of Φ40x9.8mm and weighing 8.5g, it offers a balanced blend of size and efficiency, suitable for various audio setups.
Constructed with Nd-Fe-B magnet material and featuring a magnet size of 12.5*1.5, this speaker ensures powerful magnetic flux for precise and dynamic sound reproduction. It has an impedance of 40±15% Ohm, enabling it to handle
power ratings of up to 30mW under normal conditions and up to 100mW at maximum capacity.
Operating at a frequency of 108 ±20% Hz, the RB-40040G-03R delivers clear and immersive sound with a sound pressure level (SPL) of 115±3dB. Its wide frequency range of 20-20,000Hz ensures accurate reproduction of audio across different ranges, making it suitable for various audio applications.
To ensure consistent performance, the speaker undergoes rigorous testing, including abnormal sound tests whereit is subjected to a sine wave for 50~5kHz at 1.1 Volts. It features marked polarity, with the diaphragm moving forward when a positive DC is applied to the red “+” or “Marked” terminal.
Operating reliably within a temperature range of -20°C to +55°C, the RB-40040G-03R can be safely stored between -25°C to +60°C. It undergoes durability tests such as exposure to white noise for 96 hours at 2mW input power, humidity tests, vibration tests, and drop tests to ensure reliability invarious conditions.
Furthermore, the speaker undergoes temperature cycle tests, experiencing 5 cycles ranging from 25°C to +65°C to guarantee consistent performance under extreme temperature changes. With its durable construction and reliable performance, the RB-40040G-03R is an ideal choice for demanding audio applications, providing exceptional sound quality in any environment.
