RYD YD50M16-22P250A is a φ50×16.5mm micro loudspeaker with 22Ω high impedance, designed for low-power voice output in medical devices, IoT products and consumer electronics. Rated power is 0.25W with 0.5W maximum, resonance 400Hz, response Fo~10kHz and sensitivity 86±3dB at 1m/1W. The 22Ω impedance allows direct drive from low-current circuits and easy series connection of multiple units, which is useful in alarm loops and multi-point indication systems. Its slim 16.5mm profile fits compact handheld and panel-mounted devices such as patient call systems, metering equipment, wearable alerts and smart sensors. Manufactured under the RYD ISO9001 quality system with RoHS compliant materials. Customization available: sensitivity, impedance, connection style and waterproof or dustproof options; new designs can be developed for volume programs.
