CMS-151135-076L100A-67

Speakers Overview

The CMS-151135-076L100A-67 is a general-purpose micro-speaker manufactured by Same Sky. It features a rectangular shape with top porting and an impedance of 6 Ohms. The device supports a rated power of 700 mW and a maximum power handling of 1 W. Its frequency response spans from 100 Hz to 20 kHz, with a self-resonant frequency of 600 Hz. The unit achieves a sound pressure level of 92 dBA at 700 mW/100mm. It incorporates a neodymium iron boron magnet and a polyester diaphragm. The component offers IP67 ingress protection against dust and water.

Speakers Feature Summary

• Provides robust environmental sealing with IP67 rating for dust and water resistance
• Utilizes a neodymium iron boron magnetic system for efficient audio output
• Features a polyester diaphragm designed for durability in general-purpose applications

Speakers Applications

• Medical devices requiring sealed audio components
• Electronic equipment needing dust and water resistant speakers
• General purpose audio signal indication

Speakers Procurement Notes

Verify the specific suffix configuration against the manufacturer datasheet to ensure compatibility with required mounting and termination specifications. Confirm that the IP67 rating aligns with the intended environmental exposure conditions. Check for RoHS compliance documentation if regulatory adherence is mandatory for the target market. Ensure the 6 Ohm impedance matches the driving circuit capabilities.

Speakers Selection Notes

Select this model when a rectangular form factor with top porting is required for space-constrained designs. The 6 Ohm impedance suits standard low-voltage audio drivers. Consider the 92 dBA sensitivity for applications demanding moderate acoustic output without excessive power consumption. The IP67 rating makes it suitable for harsh environments where standard open-frame speakers would fail due to moisture or particulate ingress.

Speakers Part Context

This component belongs to the CMS series of waterproof micro speakers from Same Sky. The series is engineered for electronic applications requiring reliable audio performance in challenging conditions. The rectangular design allows for flexible PCB integration compared to circular alternatives. The product line emphasizes durability through sealed construction and robust internal materials like PET diaphragms and NdFeB magnets.

Speakers Replacement Considerations

Direct substitutes within the Same Sky CMS series include CMS-15113-076SP-67, which shares similar electrical characteristics and form factors. Verify mechanical dimensions and terminal types before substitution. Cross-brand replacements require matching impedance, power ratings, and physical envelope constraints.
