SPK50-15-8N28UN

RYD SPK50-15-8N28UN is a φ52×28.3mm low-power full-range loudspeaker aimed at IoT devices, medical equipment and smart home products. It is specified at 2W rated (3W maximum) input with 8Ω impedance, 160Hz resonance, Fo~20kHz response and 83±3dB sensitivity at 1m/1W, with distortion within 5% at 1kHz. The 8Ω impedance simplifies matching with the low-voltage amplifier circuits common in portable and battery-powered products, while the compact 60g build keeps overall device weight low. Typical applications include patient monitor prompts, wearable healthcare audio, smart sensor notifications and compact voice interfaces. Manufactured under the RYD ISO9001 quality system with RoHS compliant materials. Customization available: sensitivity adjustment, connection options, waterproof and dustproof treatment, plus special temperature requests; new designs can be developed for volume programs.
