CMS-1852-24SP

Speakers Overview

The CMS-1852-24SP is a compact electromagnetic speaker manufactured by Same Sky. It features an 18 mm diameter and a depth of 5.2 mm, utilizing a paper cone and NdFeB magnet. The unit has a 4 ohm impedance and a 2 W power rating. Its frequency response spans from 460 Hz to 20 kHz, with a self-resonant frequency of 276 Hz. Operating temperatures range from -20°C to +60°C. Electrical connections are provided via solder pads.

Speakers Feature Summary

• Compact physical dimensions suitable for space-constrained designs
• Integration of neodymium iron boron magnetic material
• Paper cone construction for acoustic performance

Speakers Applications

• Consumer electronics requiring small form factor audio output
• Portable devices with limited internal volume
• Embedded systems needing integrated sound generation

Speakers Procurement Notes

Verify the specific manufacturer designation and RoHS compliance status against the latest official datasheet before finalizing procurement. Confirm that the solder pad termination type aligns with the intended assembly process. Ensure the operating temperature range meets the environmental requirements of the target application. Cross-reference the part number to avoid confusion with similar models in the series.

Speakers Selection Notes

Select this component when a low-profile speaker is required for general audio applications. The 4 ohm impedance matches common driver outputs. Consider the 460 Hz lower frequency limit for bass reproduction capabilities. Evaluate the 2 W power handling against the system's maximum voltage and current limits. Verify compatibility with the available mounting space due to the 5.2 mm depth constraint.

Speakers Part Context

This model belongs to the Same Sky CMS series of miniature speakers. It represents a standard electromagnetic transducer design using a paper diaphragm. The series offers various sizes and impedances for different audio needs. This specific variant focuses on providing adequate sound pressure levels within a minimal footprint for portable electronic devices.

Speakers Replacement Considerations

Consult the official Same Sky documentation for verified substitute part numbers. Direct replacements must match the 18 mm diameter, 4 ohm impedance, and 5.2 mm depth. Ensure any alternative maintains the same solder pad termination and NdFeB magnet composition for equivalent performance.
