CMS-272006-18E

Speakers Overview

The CMS-272006-18E is a miniature rectangular speaker manufactured by Same Sky. It features a 27 x 20 mm frame with a depth of 6.5 mm. The unit utilizes a Neodymium Iron Boron (NdFeB) magnet and a cloth cone for sound reproduction. Key electrical parameters include an impedance of 8 Ohms, a nominal input power of 1 W, and a maximum input power of 3 W. The resonance frequency is specified at 650 Hz, with a frequency response range extending from 250 Hz to 20 kHz.

Speakers Feature Summary

• Rectangular form factor with eyelets for secure mounting
• High-performance neodymium magnet construction
• Durable cloth cone diaphragm design

Speakers Applications

• General purpose audio output devices
• Miniature electronic enclosures
• Portable consumer electronics

Speakers Procurement Notes

Verify the exact datasheet version when ordering, as specifications may be updated. Confirm that the rectangular frame dimensions and eyelet placement match your mechanical design requirements. Ensure the 8 Ohm impedance aligns with your amplifier or driver circuit capabilities to prevent damage or distortion.

Speakers Selection Notes

Select this component when space constraints require a small rectangular footprint rather than a circular shape. The 1 W nominal power rating suits low-volume audio applications. Consider the 650 Hz resonance frequency when designing acoustic chambers, as it affects low-frequency performance in enclosed spaces.

Speakers Part Context

This model belongs to Same Sky's miniature speaker series, designed for compact electronic devices. The brand transitioned from CUI Devices, maintaining continuity in product lines. This specific rectangular variant offers alternative mounting options compared to standard round speakers, fitting into tight PCB layouts.

Speakers Replacement Considerations

Direct substitutes must match the 27x20mm rectangular dimensions and 8 Ohm impedance. Verify cone material compatibility if acoustic characteristics are critical. No official cross-reference part numbers are publicly confirmed for direct replacement.
