YD57M17-500PP8

RYD YD57M17-500PP8 is a φ57×17mm low-power loudspeaker with 8Ω impedance, designed for IoT devices, medical equipment and smart home audio prompts. Rated power is 0.5W (1.0W maximum), resonance 480Hz, response Fo~5kHz and sensitivity 87±3dB — a specification set that favors efficient voice reproduction at minimal amplifier output. Its 57mm diameter is a common replacement size for device refresh projects, and the standard frame simplifies drop-in upgrades of aging units. Manufactured under the RYD ISO9001 quality system with RoHS compliant materials. Customization available: sensitivity tuning, impedance variants, connection options, and waterproof or dustproof treatment; new designs can be developed for volume programs.
