CMS-3819-38SP

Speakers Overview

The CMS-3819-38SP is a general-purpose round speaker manufactured by Same Sky. It features an 8 Ohm impedance and a rated power of 3 W, with a maximum capacity of 400 mW for smaller variants in the series. The frequency response spans from 120 Hz to 15 kHz. The unit utilizes a neodymium magnet and a composite foam and paper cone. Dimensions are approximately 38.5 mm in diameter and 19 mm in depth, designed for top-port sound output.

Speakers Feature Summary

• Utilizes a neodymium magnet structure for efficient acoustic performance
• Features a composite cone material combining foam and paper elements
• Designed with a round frame configuration for standard mounting applications

Speakers Applications

• General purpose audio output devices
• Consumer electronics enclosures
• Industrial control panel indicators

Speakers Procurement Notes

Verify the specific datasheet version for the exact power rating, as listings may reference 3 W or 200 mW depending on the specific sub-variant. Confirm impedance matches the target circuit design. Check RoHS compliance status for regulatory requirements. Ensure mechanical dimensions fit the available enclosure space.

Speakers Selection Notes

Select this component when a round form factor is required. Verify that the 8 Ohm impedance aligns with the amplifier output capabilities. Consider the 19 mm depth constraint for tight enclosure designs. Evaluate the frequency range against the required audio bandwidth needs.

Speakers Part Context

This part belongs to the miniature speaker category from Same Sky, typically ranging from 10 mm to 40 mm in diameter. These components are commonly used in portable devices and compact electronic assemblies where space is limited but reliable audio reproduction is necessary.

Speakers Replacement Considerations

Check for direct substitutes within the Same Sky CMS series with matching 38 mm diameter and 8 Ohm impedance. Verify that alternative models maintain similar depth constraints and mounting hole patterns to ensure mechanical compatibility without redesigning the housing.
