Speakers datasheet and documents for CMS-2053-18SP

CMS-2053-18SP

Speakers Overview

The CMS-2053-18SP is a miniature round frame speaker manufactured by Same Sky. It features a 20mm diameter and a depth of 5.3mm. The unit operates with an 8 Ohm impedance and handles a power rating of 1.5 Watts. Its frequency response ranges from 560 Hz to 20 kHz. The construction utilizes a neodymium magnet and a cone composed of polyurethane (PU) and polybutylene terephthalate (PBT).

Speakers Feature Summary

Compact physical dimensions suitable for space-constrained designs.
Utilizes a high-strength neodymium magnet for efficient audio output.
Cone material combines polyurethane and PBT for durability.

Speakers Applications

General purpose audio indication in consumer electronics.
Miniature sound generation in portable devices.
Audio feedback systems in compact industrial equipment.

Speakers Procurement Notes

Verify the specific acoustic performance requirements against the manufacturer's datasheet before finalizing the component selection. Ensure that the mechanical mounting constraints align with the 20mm diameter and 5.3mm depth specifications provided in the official documentation. Confirm compliance with relevant environmental regulations such as RoHS standards applicable to your region.

Speakers Selection Notes

Select this component when a small form factor is critical for the enclosure design. The 8 Ohm impedance should be compatible with the driving circuitry's output capabilities. Consider the 1.5 Watt power handling limit to prevent damage during operation. The frequency range is suitable for voice or alert tones rather than full-range music reproduction.

Speakers Part Context

This speaker belongs to the miniature category within the Same Sky portfolio, designed for applications requiring low profile audio solutions. It represents a standard general-purpose driver option for manufacturers needing reliable sound output in tight spaces without compromising on magnetic efficiency or structural integrity.

Speakers Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model in the available documentation. Alternative speakers must be evaluated based on matching impedance, power rating, and physical dimensions to ensure compatibility.
