CMS-181637-158SP-X8

Speakers Overview

The CMS-181637-158SP-X8 is a miniature rectangular loudspeaker manufactured by Same Sky. It features an 8 Ohm impedance and a power rating of 1.5 W. The unit utilizes a Polyetheretherketone (PEEK) cone and a Neodymium magnet for audio transduction. Key electrical specifications include a resonant frequency of 1100 Hz and a frequency response range extending from 880 Hz to 20 kHz. The device achieves a sound pressure level of 100 dB and carries an IPX8 waterproof rating, ensuring durability in humid or wet environments.

Speakers Feature Summary

• Constructed with a durable Polyetheretherketone (PEEK) diaphragm cone for enhanced acoustic performance and longevity.
• Equipped with a high-strength Neodymium magnet system to deliver efficient audio output within a compact form factor.
• Designed with an IPX8 ingress protection rating, providing reliable operation in submerged or highly humid conditions.
• Features surface-mount solder pads for straightforward integration into printed circuit board assemblies.

Speakers Applications

• Waterproof electronic devices requiring robust audio output
• Miniature consumer electronics with space constraints
• Industrial equipment needing dust and water resistance
• Medical devices requiring sealed acoustic components

Speakers Procurement Notes

Verify the manufacturer designation as Same Sky, formerly CUI Devices, to ensure accurate sourcing. Confirm that the specific suffix X8 corresponds to the required IPX8 waterproofing and PEEK cone material. Cross-reference the 8 Ohm impedance and 1.5 W power rating against your circuit design requirements. Ensure compatibility with surface-mount assembly processes given the solder pad termination style.

Speakers Selection Notes

Select this component when a compact, rectangular speaker with high water resistance is required. The 1100 Hz resonant frequency suits applications prioritizing mid-range clarity over deep bass. The 100 dB sensitivity allows for adequate volume without excessive power consumption. Consider the physical dimensions of 18 mm x 16 mm x 3.7 mm for enclosure fitment. The PEEK cone offers superior thermal stability compared to standard paper or polymer cones.

Speakers Part Context

This model belongs to Same Sky's line of miniature loudspeakers designed for portable and ruggedized electronics. The product line emphasizes small form factors combined with high reliability standards. The transition from CUI Devices to Same Sky maintains continuity in technical specifications and manufacturing quality for existing designs.

Speakers Replacement Considerations

Direct substitutes must match the 18x16mm rectangular footprint, 8 Ohm impedance, and IPX8 rating. Verify that alternative speakers maintain similar PEEK cone construction and solder pad terminations to ensure mechanical and electrical compatibility without redesigning the PCB layout.
