CMS-3615-28SP

Speakers Overview

The Same Sky CMS-3615-28SP is a miniature round speaker with a 36 mm diameter and 15.5 mm depth. It features an 8 Ohm impedance, 2 W power rating, and neodymium magnet. The cone uses PU material, offering a frequency response up to 20 kHz and a self-resonant frequency of 276 Hz. Termination is via solder pads.

Speakers Feature Summary

• Utilizes a neodymium magnet for high efficiency in a compact form factor.
• Features a polyurethane cone material for durability and acoustic performance.
• Designed for panel mount installation with solder pad termination.

Speakers Applications

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

Speakers Procurement Notes

Verify the specific impedance and power rating against your circuit requirements before integration. Confirm that the solder pad termination style matches your PCB layout design. Ensure the physical dimensions fit within the designated enclosure space. Check for RoHS compliance documentation if required by your manufacturing standards.

Speakers Selection Notes

Select this component when a small footprint is critical but higher output is needed than typical earpiece speakers. The 8 Ohm impedance suits standard amplifier outputs. Consider the PU cone material for environments where paper cones might degrade. Verify thermal limits if operating near maximum power ratings.

Speakers Part Context

This part belongs to Same Sky's miniature speaker series, designed for tight spaces. It replaces older CUI Devices models with similar acoustic profiles. The series focuses on balancing size constraints with acceptable sound pressure levels for close-proximity listening applications.

Speakers Replacement Considerations

Check for direct equivalents from competitors like Knowles or Sonion. Verify that substitute parts match the 8 Ohm impedance and 36 mm diameter. Ensure the replacement supports solder pad termination to avoid rewiring changes.
