CMS-40504N-L152

Speakers Overview

The CMS-40504N-L152 is a miniature round speaker manufactured by Same Sky. It features a 40 mm diameter and a depth of 5 mm. The unit has an impedance of 4 ohms and a power rating of 2 watts. Its self-resonant frequency is 400 Hz, with an operating range extending to 7 kHz. The sound pressure level is rated at 91 dBA. It utilizes a neodymium magnet and a PET cone. Termination is provided via wire leads.

Speakers Feature Summary

• Compact circular design suitable for space-constrained enclosures
• High-efficiency neodymium magnetic structure
• PET cone material for consistent acoustic performance

Speakers Applications

• Portable electronic devices requiring small form factor audio output
• Industrial control panels needing clear audible alerts
• Medical equipment housing limited installation space

Speakers Procurement Notes

Verify the specific lead length requirements against the application design before ordering. Confirm that the wire termination method matches the target circuit board or connector interface. Ensure the operating temperature range aligns with the intended environmental conditions. Check for any RoHS compliance documentation if required by regional regulations. Validate the impedance match with the driving amplifier to prevent signal distortion.

Speakers Selection Notes

Choose this model when a 4-ohm impedance is required for the audio circuit. Select based on the need for a 40 mm diameter footprint within the mechanical assembly. Consider the 2-watt power handling capability relative to the maximum volume requirements. Evaluate the 91 dBA sensitivity to ensure adequate audibility without excessive amplification. Review the wire lead configuration for ease of integration into the final product.
