CMS-3150-26SP

Speakers Overview

The CMS-3150-26SP is a round electromagnetic speaker manufactured by Same Sky. It features a 31 mm diameter and a compact 5 mm depth, utilizing a Neodymium Iron Boron (NdFeB) magnet and a PU+Al cone material. The unit has an impedance of 6 Ohms and a power rating of 2 W. Its self-resonant frequency is 310 Hz, with solder pads serving as the termination type.

Speakers Feature Summary

• Compact form factor with 31 mm diameter and 5 mm depth for space-constrained designs
• High-performance magnetic circuit using Neodymium Iron Boron materials
• Durable diaphragm construction combining Polyurethane and Aluminum components

Speakers Applications

• Portable consumer electronics requiring small audio output
• Medical devices needing compact acoustic transducers
• Industrial control panels with limited mounting depth

Speakers Procurement Notes

Verify the specific suffix and packaging configuration against the official Same Sky datasheet before ordering. Confirm that the 6 Ohm impedance and 2 W power rating align with your amplifier or driver circuit capabilities. Ensure the solder pad termination method matches your PCB assembly process requirements to avoid integration issues during production.

Speakers Selection Notes

Select this model when a balance between low profile and moderate power handling is required. The 6 Ohm impedance suits standard low-voltage audio circuits. Consider the PU+Al cone material for durability in varying environmental conditions compared to paper cones. Evaluate the 310 Hz resonance frequency to ensure it fits the target application's acoustic bandwidth needs.
