CDS-20144

Overview

The CDS-20144 is a miniature general-purpose loudspeaker manufactured by Same Sky. It features an oval frame with dimensions of 20 mm x 14 mm and a height of 3.2 mm. The unit has a nominal impedance of 4 Ohms and a rated power handling capacity of 1 W, with a maximum power rating of 3 W. It utilizes a PEN cone diaphragm and a neodymium magnet for efficient sound production. The frequency response ranges from 480 Hz to 20 kHz, with a self-resonant frequency at approximately 650 Hz. The speaker delivers a sound pressure level of 79 dBA when tested at 1W/1M.

Feature Summary

• Compact oval design suitable for space-constrained applications
• High efficiency neodymium magnetic structure
• Durable PEN material cone diaphragm
• Top ported acoustic configuration

Applications

• Portable consumer electronics
• Medical devices
• Industrial control panels
• Automotive instrumentation

Procurement Notes

Verify the specific suffix (e.g., -L100) against project requirements, as lead lengths or termination styles may vary between variants. Confirm RoHS compliance status and environmental certifications prior to final integration. Ensure that the selected variant matches the required acoustic output and mechanical mounting constraints for the target enclosure design.

Selection Notes

Select this component for applications requiring high fidelity in a small form factor. The 4 Ohm impedance is compatible with standard audio amplifier outputs. Consider the top-ported design for optimal sound projection directionality. Evaluate the 1 W power rating against peak signal levels to prevent distortion or damage during operation.

Part Context

This part belongs to the CDS series of rectangular and oval micro-speakers from Same Sky. These components are designed for use in compact electronic devices where size and weight are critical factors. The series offers various impedance and power options to suit different driver circuits.

Replacement Considerations

Direct substitutes include other 4 Ohm, 1 W miniature speakers from Same Sky such as the CDS-20144-L100 variant if lead length adjustments are needed. Cross-manufacturer replacements require matching the 20x14mm footprint, 4 Ohm impedance, and similar SPL ratings.
