CDS-2844-32-SP

Overview

The CDS-2844-32-SP is a miniature round frame speaker manufactured by Same Sky. It features a 28 mm diameter with a 10 mm height and utilizes a neodymium magnet for efficient performance. The unit has a nominal impedance of 32 Ohms and a power handling capacity of 250 mW. It employs a PET cone for sound reproduction and offers a frequency response range from 480 Hz to 6.5 kHz. Termination is achieved via solder pads, facilitating integration into compact electronic assemblies.

Feature Summary

• Utilizes a neodymium magnet structure for high efficiency in a small form factor
• Incorporates a PET cone material for durable acoustic performance
• Features a round frame design suitable for space-constrained applications

Applications

• Compact consumer electronics audio output
• Portable device speaker modules
• Miniature alarm or notification systems

Procurement Notes

Verify the specific impedance and power rating requirements against the system design specifications before procurement. Confirm that the solder pad termination method aligns with the intended assembly process. Ensure the physical dimensions fit within the designated enclosure constraints. Check for any specific environmental ratings if the application involves extreme temperatures or humidity.

Selection Notes

Select this component when a low-profile, round speaker is required for devices with limited internal volume. The 32 Ohm impedance matches common audio amplifier outputs. Consider the 250 mW power rating to ensure adequate volume levels without distortion. The neodymium magnet provides strong magnetic flux density, contributing to better sensitivity compared to ferrite alternatives in similar sizes.

Part Context

This speaker belongs to the Same Sky miniature speaker series, designed for modern portable electronics. The CDS-2844-32-SP specifically addresses the need for high-quality audio in slim devices. It represents a balance between acoustic performance and physical size, leveraging advanced magnet materials to maximize output within a restricted footprint.

Replacement Considerations

Direct substitutes must match the 28 mm diameter, 32 Ohm impedance, and 250 mW power rating. Verify that alternative speakers maintain the same mounting hole pattern and terminal configuration to ensure mechanical compatibility without redesigning the PCB or enclosure.
