YD50M17A-250P8EW100

RYD YD50M17A-250P8EW100 is a 51×51×17mm square micro loudspeaker for space-critical IoT, medical and smart home designs. It is rated at 0.25W (0.5W maximum) with 8Ω impedance, 350Hz resonance, a Fo~4kHz voice-focused range and 85±3dB sensitivity at 1m/1W, keeping distortion within 5% at 1kHz. The low-profile square frame and 52.5g weight suit intercom terminals, access control panels, portable medical devices and home automation controllers that need clear voice prompts rather than music playback. Manufactured under the RYD ISO9001 quality system with RoHS compliant materials. Customization available: sensitivity tuning, impedance variants, connection style and lead wire length, plus waterproof or dustproof protection; volume programs may include new development.
