DMS2308-02B

RYD DMS2308-02B is a φ23×4.0mm high-output micro speaker delivering 97±3dB at 1W/0.1m. Rated input is 1.0W (2.0W max) at 8Ω, resonance 820Hz, effective range Fo~5kHz, distortion within 5%. This SPL level is unusual for a 4mm-thick unit and suits applications needing audible alerts over ambient noise: industrial handheld terminals, medical equipment alarms, outdoor IoT devices and automotive cabin prompts. The internal-magnet circuit uses a φ8.2×1.2mm neodymium magnet with 0.6T flux density. Manufactured under the RYD ISO9001 quality system with RoHS compliant materials. Customization available: sensitivity, impedance, connection style and waterproof or dustproof grade; new designs can be developed for volume programs. Contact RYD to verify sound level targets.
