CMS-3642-2SP

Speakers Overview

The CMS-3642-2SP is a miniature round speaker manufactured by Same Sky. It features a 36 mm diameter frame with a depth of 4.2 mm. The unit utilizes a Neodymium (NdFeB) magnet and a PET cone material. It has an impedance of 4 Ohms and a rated power handling capacity of 2 Watts. The self-resonant frequency is specified at 580 Hz, with a frequency response range extending from 304 Hz to 10 kHz. Electrical connections are provided via solder pads.

Speakers Feature Summary

• Compact circular design suitable for space-constrained enclosures
• High-performance neodymium magnetic structure for efficient audio output
• Durable polyethylene terephthalate cone material
• Direct solder pad termination for simplified PCB integration

Speakers Applications

• Portable consumer electronics
• Medical diagnostic devices
• Industrial control panels
• Automotive interior audio systems

Speakers Procurement Notes

Verify the specific datasheet version when ordering, as manufacturer specifications may undergo revisions. Confirm that the solder pad layout matches your printed circuit board design requirements. Ensure the operating environment remains within the standard temperature limits defined in the official documentation to maintain acoustic performance and structural integrity over the product lifecycle.

Speakers Selection Notes

Select this component when a low-profile, high-efficiency audio transducer is required for compact assemblies. The 4-ohm impedance allows for direct driving from many common amplifier outputs without additional matching networks. Consider the 580 Hz resonance point when designing acoustic chambers or filters to avoid unwanted feedback or distortion in the target application frequency band.

Speakers Part Context

This model belongs to the Same Sky line of general-purpose speakers, formerly associated with CUI Devices. The series focuses on providing reliable audio solutions for mass-market electronic devices. The CMS-3642-2SP represents a balance between acoustic fidelity and physical miniaturization, catering to industries requiring robust sound reproduction in small form factors.

Speakers Replacement Considerations

Check for CMS-3642-2SP-TR if reel packaging is preferred over bulk. Verify mechanical compatibility before substituting with other 36mm round speakers, as mounting hole patterns and terminal positions may vary between different manufacturers' versions.
