The SPEAKERS & TRANSDUCERS CMS-181325-078S-67 from SAME SKY is a high-quality, miniature audio device designed for demanding applications requiring compact size and reliable performance. This micro-speaker features an IP67 rated face, providing excellent protection against dust and water ingress, making it suitable for outdoor and rugged environments.
Constructed with a durable Nd-Fe-B magnet and a mylar cone, this 18 x 13 x 2.5 mm speaker delivers clear audio output with a sound pressure level of up to 96 dB at 0.7 W. Its impedance ranges from 6.8 to 9.2 ohms, optimized for various electronic systems. The device supports a maximum input power of 0.7 W, with a frequency response spanning 500 Hz to 10 kHz, ensuring accurate sound reproduction across a broad spectrum.
Designed for easy integration, it offers three contact methods: spring contacts, solder pads, or wire leads, and can be hand-soldered at up to 380°C for quick assembly. The device operates reliably within temperatures from -20°C to 70°C and can be stored between -40°C and 85°C. Weighing only 1.8 grams, it is ideal for space-constrained applications.
