The CMS-15118D-SP is a micro-speaker designed for compact audio applications, featuring a small footprint and low profile construction. It operates at 8 ohm impedance with a maximum input power of 0.7 W to 1.0 W, and delivers a sound pressure level of 88 to 94 dB at 0.7 W measured at 0.1 m and 1.0 kHz in a 1 cc closed box. The speaker has a resonant frequency ranging from 425 to 575 Hz in free air, and 807.5 to 1092.5 Hz in a 1 cc closed box, with a frequency response extending to 10,000 Hz. The device features a PEEK cone material with an Nd-Fe-B magnet, operates across -30°C to +75°C, and is RoHS compliant. This micro-speaker is ideal for portable electronics, hearing aids, notification devices, and other space-constrained applications requiring compact audio output.
