CMS-15118E-SP is a micro-speaker designed for compact audio applications requiring a small footprint and low profile form factor. The speaker features a neodymium-iron-boron (Nd-Fe-B) magnet with a PEEK cone material and PPA housing, delivering a maximum input power of 0.8 W (typical) with an impedance of 8 O at 1.5 kHz. It exhibits a resonant frequency range of 550–850 Hz (typical) in a 1 cc closed box and produces a sound pressure level of 90.5 dB (typical) at 0.8 W measured at 0.1 m, with frequency response extending to 10 kHz. The device operates over a temperature range of -20°C to +60°C and features spring contact terminals for reliable electrical connection. This micro-speaker is ideal for portable consumer electronics, hearing aids, notification systems, and other space-constrained audio applications where compact size and reliable performance are essential.
