CMS-4049-28S

Speakers Overview

The CMS-4049-28S is a dynamic speaker manufactured by Same Sky, formerly CUI Devices. It features an 8-ohm impedance and a rated power of 1 W, with a maximum power handling of 2 W. The device operates within a frequency range of 500 Hz to 20 kHz and delivers a sound pressure level of 93 dBA at 100 mW/100mm. Its circular design includes a top port and spring-type terminals. The physical dimensions are 40.00 mm in diameter and 8.40 mm in height.

Speakers Feature Summary

• Utilizes a polyester (PET) diaphragm for acoustic performance
• Incorporates an N38 magnet structure
• Features spring-type terminals for connection

Speakers Applications

• General audio output devices
• Compact electronic enclosures requiring top-port speakers

Speakers Procurement Notes

Verify the manufacturer designation as Same Sky or CUI Devices when sourcing. Confirm the specific suffix '28S' matches the required terminal type and mounting configuration. Ensure compliance with RoHS3 standards if environmental regulations apply to the final assembly. Cross-reference electrical parameters against the official datasheet to guarantee compatibility with the target circuit.

Speakers Selection Notes

Select this component based on its 8-ohm impedance and 1 W power rating for low-power applications. The 93 dBA efficiency supports clear audio output in small form factors. Consider the 40 mm diameter and 8.40 mm height constraints for enclosure integration. The top-port design influences acoustic placement relative to other components.

Speakers Part Context

This model belongs to the SP Micro Speaker series, designed for compact audio solutions. It serves as a direct replacement for the Soberton Inc. SP-4005S. The product maintains similar electrical and mechanical specifications, ensuring interchangeability in existing designs without requiring significant layout modifications.

Speakers Replacement Considerations

The CMS-4049-28S is documented as a substitute for the Soberton Inc. SP-4005S. Verify that the terminal type and mounting dimensions are compatible with the original design before implementation.
