CMS-201437-24SP-X8

Speakers Overview

The CMS-201437-24SP-X8 is a rectangular general-purpose speaker manufactured by Same Sky. It features a power rating of 2 W and an impedance of 4 Ohms. The unit operates within a frequency range of 840 Hz to 20 kHz, with a resonant frequency specified at approximately 1050 Hz or 102 dB sensitivity. Physical dimensions are 20 mm x 14 mm with a depth of 3.7 mm, utilizing Peek material and Nd-Fe-B magnets. Termination is achieved via solder pads, and the device meets IPX8 waterproof standards.

Speakers Feature Summary

• IPX8 waterproof protection for reliable operation in wet environments
• Rectangular form factor with compact 20 mm x 14 mm footprint
• Solder pad termination for direct PCB integration
• High-performance magnetic structure using Neodymium Iron Boron

Speakers Applications

• Waterproof electronic devices requiring audio output
• Consumer electronics with strict environmental sealing needs
• Compact embedded systems with limited spatial constraints

Speakers Procurement Notes

Verify the specific resonant frequency specification (840 Hz vs 1050 Hz) against the official manufacturer datasheet prior to final design approval, as sources vary. Confirm that the IPX8 rating aligns with your system's immersion requirements. Ensure solder pad compatibility with your assembly process. Cross-reference the exact physical depth of 3.7 mm with your enclosure design to prevent mechanical interference.

Speakers Selection Notes

Select this component when a small, rectangular speaker with high water resistance is required. The 4 Ohm impedance suits standard low-voltage audio drivers. Consider the 2 W power handling for moderate volume applications. The solder pad termination simplifies surface-mount assembly compared to wire leads. Evaluate the 20x14mm size against available board space.

Speakers Part Context

This speaker belongs to Same Sky's lineup of compact transducers, formerly associated with CUI Devices. It represents a specialized solution for applications demanding both acoustic performance and environmental durability. The product integrates advanced materials like Peek and Nd-Fe-B to achieve its specifications within a minimal profile suitable for modern portable and sealed electronic designs.

Speakers Replacement Considerations

Direct substitutes must match the 20x14mm rectangular outline, 4 Ohm impedance, and IPX8 rating. Verify that alternative speakers maintain similar power handling and frequency response characteristics. Ensure the replacement supports solder pad termination and fits the 3.7 mm height constraint.
