CMS-201438-058S

Speakers Overview

The CMS-201438-058S is a miniature general-purpose speaker manufactured by Same Sky. It features an oval frame with dimensions of 20 x 14 x 3.8 mm. The unit operates at an impedance of 8 Ohms and has a nominal power handling capacity of 500 mW. It utilizes a neodymium magnet and a PEN cone for acoustic performance. The frequency response range spans from 640 Hz to 20 kHz, providing suitable audio reproduction for compact electronic applications.

Speakers Feature Summary

• Compact oval form factor designed for space-constrained assemblies
• Neodymium magnetic structure for efficient sound generation
• PEN cone diaphragm material for durability

Speakers Applications

• Miniature consumer electronics
• Portable communication devices
• Compact alarm systems

Speakers Procurement Notes

Verify the specific acoustic parameters against the official Same Sky datasheet before integration. Confirm that the 500 mW power rating aligns with the target application's drive requirements. Ensure the 8 Ohm impedance matches the amplifier output specifications to prevent signal distortion or component damage during operation.

Speakers Selection Notes

Select this model when a low-profile rectangular shape is required for internal mounting. The 8 Ohm impedance suits standard low-voltage audio drivers. Consider the 640 Hz lower frequency limit; it is not suitable for full-range bass reproduction but fits mid-to-high frequency roles in small enclosures where physical depth is limited to under 4 mm.

Speakers Part Context

This component belongs to the Same Sky speaker portfolio, formerly associated with CUI Devices. It represents a standard passive transducer solution for OEMs requiring reliable audio output in minimal footprints. The product line emphasizes compatibility with automated assembly processes due to its standardized terminal configuration.

Speakers Replacement Considerations

Direct substitutes require matching the 20x14mm footprint, 8 Ohm impedance, and similar power handling. Verify mechanical clearance for the 3.8mm depth. Cross-reference with other Same Sky oval speakers if exact availability is constrained.
