CMS-2850-058SP

Speakers Overview

The CMS-2850-058SP is a general-purpose magnetic audio speaker manufactured by Same Sky. It features an 8 Ohm impedance and a rated power of 500 mW, with a maximum power handling of 600 mW. The unit utilizes a neodymium iron boron magnet and a polyethylene terephthalate (PET) cone. Its frequency range spans from 400 Hz to 20 kHz, with a self-resonant frequency of 500 Hz. The speaker has a round shape with a top port location, measuring 28 mm in diameter and 5 mm in depth. It employs solder pad terminations for circuit board mounting.

Speakers Feature Summary

• Utilizes a neodymium iron boron magnet for efficient acoustic performance
• Features a polyethylene terephthalate cone material for durability
• Designed with a top port configuration for sound projection
• Constructed with a round frame suitable for compact enclosures

Speakers Applications

• General purpose audio output devices
• Compact electronic enclosures requiring low profile speakers
• Consumer electronics with limited internal space
• Industrial control panels needing audible feedback

Speakers Procurement Notes

Verify the manufacturer designation as Same Sky, formerly CUI Devices, to ensure component authenticity. Confirm that the specific model suffix matches the required electrical parameters, particularly the 8 Ohm impedance and 500 mW rating. Check for RoHS compliance documentation if environmental regulations apply to the final assembly. Ensure solder pad termination compatibility with the intended PCB layout before procurement.

Speakers Selection Notes

Select this component when a low-profile, round speaker is required for general audio applications. The 28 mm diameter and 5 mm depth make it suitable for tight spatial constraints. The PET cone and NdFeB magnet combination offers a balance of cost and performance. Verify that the 400 Hz to 20 kHz frequency response meets the specific audio requirements of the design.

Speakers Part Context

This part belongs to the miniature speaker category within the Same Sky portfolio. It is designed for applications where size is a critical factor. The series typically includes various impedances and power ratings to suit different driver capabilities. The top port design distinguishes it from rear-port variants, affecting enclosure acoustic tuning strategies.

Speakers Replacement Considerations

CMS-2850-158SP is a documented alternative offering higher power handling. CMS-305-158SP provides a larger diameter option with increased output. Verify mechanical dimensions and impedance matching when substituting to ensure proper fit and electrical compatibility.
