CMS-151125-078SP-67

Speakers Overview

The CMS-151125-078SP-67 is a rectangular micro speaker manufactured by Same Sky. It features an 8-ohm impedance and a power rating of 700 mW. The device operates within a frequency range of 100 Hz to 20 kHz, with a self-resonant frequency of 700 Hz. It delivers a sound pressure level of 91 dBA at 700 mW/100mm. The unit measures 15 mm in length, 11 mm in width, and 2.5 mm in height. It utilizes solder pads for termination and incorporates a neodymium iron boron magnet with a polyester diaphragm.

Speakers Feature Summary

• IP67 rated enclosure providing dust and water protection for reliable operation in harsh environments
• Top port design facilitates acoustic coupling in compact sealed enclosures
• Spring-type solder pad termination enables secure board mounting without through-hole drilling

Speakers Applications

• Medical devices requiring waterproof audio components
• Industrial equipment exposed to moisture or dust
• Consumer electronics needing compact high-efficiency speakers

Speakers Procurement Notes

Verify the specific suffix configuration against the official datasheet to ensure correct impedance and terminal type. Confirm IP67 sealing integrity requirements match the application environment. Check RoHS compliance documentation for regulatory adherence. Ensure PCB footprint matches the specified solder pad dimensions. Validate operating temperature ranges against system constraints.

Speakers Selection Notes

Select this component when IP67 protection is mandatory for audio output in confined spaces. The top port orientation suits designs where rear access is restricted. Compare efficiency metrics against alternative models if higher volume is required. Consider the 8-ohm impedance for amplifier matching. Evaluate the 2.5 mm profile against strict height limitations.

Speakers Part Context

This model belongs to the CMS series of micro speakers from Same Sky. It represents a specialized variant designed for rugged applications. The series typically includes various impedance and port configurations. This specific part integrates waterproofing into a standard rectangular form factor. It serves as a drop-in solution for legacy CUI Devices designs requiring enhanced environmental sealing.

Speakers Replacement Considerations

CMS-15113-076SP lacks the IP67 rating and differs in impedance. CMS-181325-078S-67 offers similar specs but uses spring contacts instead of solder pads. Verify mechanical fit and electrical parameters before substitution.
