CMS-160925-078SP-67

Speakers Overview

The CMS-160925-078SP-67 is a rectangular general-purpose speaker manufactured by Same Sky. It features an 8-ohm impedance and a rated power of 700 mW, with a maximum power handling capacity of 1 W. The device utilizes a neodymium iron boron magnet and a polyester (PET) diaphragm. Designed for surface-mount applications, it employs solder pad termination. The unit measures 16 mm in length, 9 mm in width, and 2.5 mm in height, offering a compact form factor suitable for space-constrained electronic assemblies.

Speakers Feature Summary

• IP67 waterproof rating for environmental protection
• Rectangular shape with top port design
• Surface-mount solder pad termination

Speakers Applications

• Waterproof consumer electronics
• Medical devices requiring sealed audio components
• Industrial equipment needing dust and water resistance

Speakers Procurement Notes

Verify the specific suffix -67 to confirm IP67 sealing compliance, as standard variants may lack this rating. Ensure the PCB layout accommodates the 16x9mm outline and 2.5mm height constraints. Confirm that the soldering process supports the specified surface-mount termination type without damaging the sealed housing.

Speakers Selection Notes

Select this component when a sealed audio solution is required for harsh environments. The 8-ohm impedance matches standard amplifier outputs. Consider the 550 Hz self-resonant frequency for acoustic tuning. The top-port configuration directs sound outward from the flat surface, influencing enclosure design compared to rear-ported alternatives.

Speakers Part Context

This model belongs to the CMS series of micro speakers from Same Sky, formerly CUI Devices. The series includes various sizes and ratings, with the CMS-160925 designation indicating the specific 16x9mm footprint. The -67 suffix typically denotes the IP67 waterproof variant within this dimensional family.

Speakers Replacement Considerations

CMS-160925-078SP is the non-waterproof counterpart. Verify if IP67 sealing is mandatory before substituting. Other Same Sky models like CMS-181325-078SP differ in dimensions and must be evaluated for mechanical fit.
