CMS-151125-076L100B-67

Overview

The CMS-151125-076L100B-67 is a rectangular micro-speaker manufactured by Same Sky, designed for compact audio applications. It features a 15 x 11 mm footprint with a height of 2.5 mm. The unit operates at a nominal voltage of 5V and has an impedance of 6 Ohms. It delivers a sound pressure level of 85 dB at 1W/10cm and resonant frequency of 550 Hz. The speaker utilizes a neodymium magnet and PEEK cone for durability. It is rated IPX7 for water resistance, making it suitable for harsh environments.

Feature Summary

• IPX7 waterproof rating for protection against immersion in water
• Compact rectangular frame design optimized for space-constrained enclosures
• PEEK cone material provides enhanced durability and thermal stability
• Neodymium magnet structure ensures high efficiency in small form factor

Applications

• Medical devices requiring sterilization or fluid exposure resistance
• Outdoor consumer electronics exposed to moisture
• Industrial equipment needing robust audio feedback
• Portable health monitoring wearables

Procurement Notes

Verify the specific suffix 'B' against the manufacturer's latest datasheet to confirm exact acoustic and environmental specifications. Ensure the IPX7 rating aligns with your application's immersion requirements. Confirm lead times as production cycles may vary. Check for RoHS compliance documentation if required for your region. Validate that the 6 Ohm impedance matches your amplifier output capabilities.

Selection Notes

Select this model when space is limited to a 15x11mm area and waterproofing is critical. Compare against standard speakers if IP67/IPX7 ratings are not needed to reduce cost. Consider the 550 Hz resonance frequency for voice vs. music fidelity needs. Evaluate the 85 dB SPL against ambient noise levels in the target environment. Ensure the 2.5mm height fits within the device chassis constraints.

Part Context

This component belongs to Same Sky's micro-speaker lineup, specifically engineered for miniaturized audio solutions. It replaces older CUI Devices models under the same naming convention after the brand transition. The series focuses on balancing acoustic performance with physical ruggedness. It is part of a broader portfolio of transducers including buzzers and larger speakers.
