CMS-40558N-L152A

Speakers Overview

The CMS-40558N-L152A is a micro speaker manufactured by Same Sky, formerly CUI Devices. It features a round frame with dimensions of 40 mm in diameter and 5.5 mm in depth. The unit utilizes a neodymium iron boron magnet and a PET cone to deliver audio output. It has an impedance of 8 ohms and a power rating of 500 mW (0.5 W). The frequency response ranges from 400 Hz to 6 kHz, with a resonant frequency of 500 Hz. The sound pressure level is rated at 90 dBA. Electrical connections are provided via wire leads equipped with a connector.

Speakers Feature Summary

• Utilizes a neodymium magnet for efficient magnetic field generation within a compact form factor.
• Features a PET cone designed for durability and consistent acoustic performance.
• Includes integrated wire leads with a connector for simplified circuit integration.

Speakers Applications

• Panel mount audio output devices
• General purpose speaker applications requiring low power consumption
• Compact electronic enclosures needing round frame speakers

Speakers Procurement Notes

Verify the specific connector type on the wire leads against your system requirements before procurement. Confirm that the 8-ohm impedance matches your amplifier or driver circuit capabilities. Ensure the operating temperature range of -30°C to +70°C aligns with your intended environment. Check for RoHS compliance documentation if required by your manufacturing standards.

Speakers Selection Notes

Select this component when a small, round profile is necessary for panel mounting. The 500 mW power handling is suitable for low-volume audio signals. Consider the 90 dBA sensitivity for applications requiring moderate loudness without high drive power. The integrated connector simplifies assembly compared to soldered terminals.

Speakers Part Context

This model belongs to the Same Sky micro speaker series, which focuses on compact audio solutions. The manufacturer, Same Sky, acquired CUI Devices, retaining their product lines under the new branding. This specific part represents a standard general-purpose speaker design optimized for space-constrained electronics.

Speakers Replacement Considerations

The CMS-40558N-L152B is a related variant within the same series. Verify dimensional compatibility and electrical specifications before substituting. Ensure the connector type and wire lead configuration match your existing harness or PCB layout requirements.
