CM-23299-000

Overview

The Knowles CM-23299-000 is a balanced armature receiver speaker designed for high-power hearing aid applications. It features a top round port configuration and operates within a frequency range of 100 Hz to 5 kHz. The device has an impedance of 150 Ohms and delivers a sound pressure level of 106 dBA. It utilizes medium DCR to impedance ratio technology, offering performance comparable to EF receivers in similar physical dimensions.

Feature Summary

• Balanced armature transducer design optimized for acoustic efficiency
• Top round port configuration for directional sound projection
• Medium DCR to impedance ratio architecture for power handling

Applications

• High-power hearing aids
• Medical audio devices requiring compact receivers
• Hearing assistance systems with specific size constraints

Procurement Notes

Verify the exact part number against official Knowles Acoustics documentation to ensure compatibility with hearing aid designs. Confirm that the 150 Ohm impedance and 106 dBA sensitivity meet specific acoustic requirements. Check for any recent revisions or alternative series members if supply chain adjustments are necessary.

Selection Notes

Select this component when a compact, high-power balanced armature receiver is required for hearing aid applications. Consider its similarity to EF receivers regarding size and performance characteristics. Ensure the application can accommodate the 150 Ohm impedance load and benefits from the specified frequency response range.

Part Context

This component belongs to the CM series of balanced armature speakers manufactured by Knowles Acoustics. The series is widely used in the hearing healthcare industry for providing clear audio output in small form factors. The CM-23299-000 specifically targets high-power needs while maintaining a footprint similar to established EF receiver standards.

Replacement Considerations

EF series receivers may serve as functional substitutes due to similar size and application profiles. Verify electrical parameters such as impedance and sensitivity before substitution.
