Headset Speaker RB-E07032G-001R
The RB-E07032G-001R is a compact and lightweight headset speaker designed for earphone applications, offering exceptional audio performance in a small form factor. With a diameter of Φ7.0mm and a thickness of 4.2mm, weighing just 0.4g, this speaker is ideal for integration into various portable audio devices.
Constructed with Nd-Fe-B magnet material, the RB-E07032G-001R features a unique magnet size of Φ3.0×0.8T, maintaining an impedance of 32±15% Ohm, ensuring compatibility with a wide
range of audio equipment. It has a power rating of 2mW under normal conditions, with a maximum power handling capability of 5mW, providing clear and balanced sound output.
As an earphone speaker, the RB-E07032G-001R does not have a fundamental output (FO) frequency. However, it delivers a sound pressure level (SPL) of 92±3dB across the entire frequency range of 20-20,000Hz, offering immersive audio experiences with detailed sound reproduction.
With distortion limited to a maximum of 5%, thisspeaker ensures distortion-free sound even at higher volume levels, enhancing the overall listening experience. During abnormal sound tests, it undergoes rigorous testing with a sine wave ranging from 20~2kHz at 0.30 Volts to ensure optimal performance and reliability.
Ensuring correct polarity for proper operation, the diaphragm of the RB-E07032G-001R moves forward when a positive DC is applied to the red “+” or “Marked” terminal. Operating within a temperature range of -20°C to+55°C, the speaker remains functional and reliable even in varying temperature conditions. It has a corresponding storage temperature range from -25°C to +60°C, ensuring longevity and performance over time.
The RB-E07032G-001R undergoes load testing, including exposure to white noise for 96 hours at 2mW input power. Additionally, it endures high-temperature tests at +60±2°C and low-temperature tests at -25±2°C, each lasting 96 hours, along with a humidity test at +40±2°C with arelative 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 evaluate its resilience to vibrations. Furthermore, it undergoes a drop test where it is subjected to a 1 M free fall on a concrete floor, repeated 10 times to assess its durability under impact.
Additionally, the speaker must pass a temperature cycle test involving exposure to temperatures ranging from 25°C to+65°C, repeated for 5 cycles, to ensure its reliability under temperature variations. With its compact design and impressive performance, the RB-E07032G-001R headset speaker is an excellent choice for delivering high-quality audio experiences in earphones and headsets.
