CDS-2357-32-SP

Overview

The CDS-2357-32-SP is a miniature general-purpose speaker manufactured by Same Sky. It features a round frame with dimensions of Ø23x5.7mm and a panel cutout diameter of 12.5mm. The unit operates at an impedance of 32 Ohms with a rated power of 0.5 W and a maximum power handling of 1 W. It utilizes a neodymium magnet and a PET cone, delivering a sound pressure level of 87 dB. The frequency response ranges from 640 Hz to 10 kHz, with a self-resonant frequency of approximately 900 Hz.

Feature Summary

• Utilizes a high-strength neodymium magnet for efficient acoustic output in a compact form factor.
• Features a durable polyethylene terephthalate (PET) cone designed for consistent performance.
• Designed for top-port sound projection within a standard round frame geometry.

Applications

• Miniature audio devices requiring low power consumption
• Medical equipment with space constraints
• Portable consumer electronics

Procurement Notes

Verify the specific suffix SP indicates the tape-and-reel packaging configuration if automated assembly is required. Confirm RoHS3 compliance status through the official certificate of conformity provided by Same Sky. Ensure the operating temperature range of -20°C to 60°C aligns with the final product environment. Cross-reference the datasheet for any recent material changes or PCN notifications regarding plating or housing materials.

Selection Notes

Select this component when a 32 Ohm impedance matches the amplifier output stage. The 0.5 W rating suits low-volume applications where efficiency is prioritized over raw volume. The 12.5mm cutout requirement must be accommodated in the enclosure design. Consider the 87 dB sensitivity for adequate audibility in quiet environments without excessive drive current.

Part Context

This model belongs to the CDS series of rectangular and round micro-speakers from Same Sky. These components are engineered for integration into compact electronic systems where traditional speakers cannot fit. The series emphasizes reliability and standardized mounting dimensions for easy design-in across various portable device categories.

Replacement Considerations

Direct substitutes require matching the 32 Ohm impedance, 23mm diameter, and 0.5W power rating. Verify that alternative models support the same 12.5mm panel cutout and top-port orientation. Check compatibility with existing PCB footprints and terminal configurations.

FAQ

What is the recommended panel cutout diameter for installation?

The specified panel cutout diameter is 12.5mm to ensure proper mounting and acoustic sealing.

Does this speaker include a built-in switch?

No, the CDS-2357-32-SP is a passive transducer without an integrated internal switch.
