CM-23152-000

Overview

The CM-23152-000 is a balanced armature receiver speaker manufactured by Knowles. It features a 150 Ohms impedance and operates within a frequency range of 100 Hz to 5 kHz. The device utilizes a top round port design with a sensitivity rating of 107 dB. This component is classified as an audio product suitable for integrated sound applications.

Feature Summary

• Balanced armature transducer technology
• Top round port acoustic design
• 150 Ohms nominal impedance

Applications

• Audio receiver modules
• Integrated sound systems
• Compact electronic devices requiring balanced armature speakers

Procurement Notes

Verify the specific datasheet version for exact sensitivity tolerances, as sources indicate variations between 107 dB and 110 dB. Confirm RoHS compliance status directly with the manufacturer or authorized distributor, as documentation indicates potential non-compliance in certain batches. Ensure the top round port configuration matches the mechanical requirements of the target enclosure.

Selection Notes

Select this component when a balanced armature architecture is required for high-fidelity audio reproduction in space-constrained designs. The 150 Ohms impedance must align with the driving circuit's output capabilities. Consider the 100 Hz to 5 kHz frequency response limits to ensure suitability for the intended voice or audio bandwidth requirements.

Part Context

This part belongs to Knowles' audio products portfolio, specifically within the speakers category. It is distinct from their passive components like MLCCs. The model number identifies a specific balanced armature receiver variant characterized by its impedance and porting style.

Replacement Considerations

Direct substitutes require matching the 150 Ohms impedance, balanced armature type, and similar frequency response. Verify mechanical dimensions and port orientation (top round) to ensure compatibility with existing PCB layouts and acoustic chambers.
