CMS-28528N-L152

Speakers Overview

The CMS-28528N-L152 is a round electromagnetic speaker manufactured by Same Sky. It features an 8 Ohm impedance and a rated power of 2 W, with a maximum power handling of 3 W. The frequency range spans from 600 Hz to 20 kHz, with a self-resonant frequency at 750 Hz. The unit has a 28 mm diameter and a depth of 5.2 mm. It utilizes a neodymium iron boron magnet and a polyester cone. Sound output is measured at 90 dBA efficiency at 1W/1M. Termination is provided via wire leads.

Speakers Feature Summary

• Round frame construction with top porting for acoustic projection
• Neodymium iron boron magnetic system for compact high-performance output
• Polyester cone material for durability and consistent response
• Wire lead termination for flexible circuit integration

Speakers Applications

• General purpose audio transduction in consumer electronics
• Portable device sound output modules
• Industrial control panel audio indicators
• Medical equipment acoustic signaling

Speakers Procurement Notes

Verify the specific suffix L152 to confirm wire lead length and connector type compatibility with your assembly requirements. Ensure the 8 Ohm impedance matches your amplifier or driver circuit design. Confirm RoHS3 compliance status if operating in regulated regions. Cross-reference the 2 W rating against your thermal management capabilities to prevent damage during peak operation.

Speakers Selection Notes

Select this component when a round form factor and 8 Ohm impedance are required. The 28 mm diameter suits applications with limited spatial constraints but needing moderate output. Compare against the CLS series if PET cones or different mounting styles are preferred. Consider the 5.2 mm depth for enclosure clearance calculations. Evaluate the 600 Hz lower frequency limit against your bass reproduction needs.

Speakers Part Context

This part belongs to the Same Sky miniature speaker portfolio, designed for space-constrained audio applications. It complements rectangular options like the CDS series by offering a circular footprint. The product line emphasizes high sensitivity and reliable performance in small enclosures. It serves as a direct replacement for legacy CUI Devices speakers with similar electrical and mechanical specifications.

Speakers Replacement Considerations

Direct substitutes include other 28 mm round speakers with 8 Ohm impedance and comparable power ratings. Verify mechanical dimensions, specifically the 5.2 mm depth and mounting hole patterns. Check that the replacement maintains the 90 dBA sensitivity level to ensure equivalent volume output. Ensure the new part supports the same operating temperature range.
