CMS-28588N-L152A

Speakers Overview

The CMS-28588N-L152A is a micro speaker manufactured by Same Sky, designed for integration into compact electronic devices. It features a round frame with a diameter of 28 mm and a depth of 5.5 mm. The unit utilizes a neodymium iron boron magnet and a PEI cone to deliver audio output. It operates at an impedance of 8 ohms with a power rating of 2 watts. The resonant frequency is specified at 550 Hz, and it achieves a sound pressure level of 99 dBA. The component connects via wire leads and includes a connector. It functions within a temperature range of -20°C to +55°C.

Speakers Feature Summary

• Utilizes a neodymium iron boron magnet for efficient magnetic flux density in a compact form factor.
• Features a PEI cone material designed for durability and consistent acoustic performance.
• Includes integrated wire leads with a connector for simplified circuit assembly.

Speakers Applications

• Portable consumer electronics requiring small form-factor audio output
• Industrial control panels with limited internal space
• Medical devices needing reliable miniaturized sound components

Speakers Procurement Notes

Verify the exact suffix against official Same Sky documentation, as variations such as L152B exist. Confirm mechanical mounting requirements and connector type compatibility with your specific PCB design. Ensure thermal operating limits align with your device's environmental conditions. Request updated datasheets directly from the manufacturer or authorized distributors to confirm current RoHS compliance status and lead times before finalizing procurement plans.

Speakers Selection Notes

Select this component when a 28 mm round profile fits the enclosure constraints. The 8-ohm impedance matches standard amplifier outputs. Consider the 550 Hz resonant frequency for voice or alert applications rather than full-range music. Verify that the 2-watt power handling meets the required volume levels without distortion. Check if the included connector type suits the system wiring architecture.

Speakers Part Context

This part belongs to the Same Sky CMS series of micro speakers. The series offers various sizes and configurations for embedded audio solutions. The CMS-28588N-L152A represents a specific variant within this lineup, distinguished by its 28 mm diameter and specific electrical characteristics.
