CI-22955-000

Overview

The Knowles CI-22955-000 is a balanced armature transducer engineered for audio applications. It functions as a dedicated low-frequency driver within multi-driver in-ear monitor architectures. The component utilizes a proprietary diaphragm design optimized for robust bass reproduction with low distortion. It operates within standard audio frequency ranges, providing high output and precise transient response suitable for professional monitoring and consumer audio devices.

Feature Summary

• Optimized low-frequency response with extended bass extension
• Low-distortion performance via specialized diaphragm engineering
• High sensitivity for efficient power utilization
• Compact form factor designed for integration into small enclosures

Applications

• In-ear monitor bass drivers
• Professional audio monitoring systems
• Consumer earphone assemblies

Procurement Notes

Verify the specific suffix and revision code against the manufacturer's current datasheet to ensure compatibility with intended acoustic chambers. Confirm RoHS compliance status if required by regional regulations. Check for availability of matching acoustic filters or housings from authorized distributors to maintain specified frequency response characteristics.

Selection Notes

Select this component when a dedicated low-frequency balanced armature is required in a multi-way earphone design. It complements midrange and treble drivers to create a full-spectrum audio experience. Consider its size and mounting requirements relative to the earpiece housing dimensions during the mechanical design phase.

Part Context

This part belongs to the Knowles Balanced Armature family, widely recognized for precision audio transduction. The CI series specifically targets compact audio solutions, offering consistent performance across production batches. It is commonly paired with other Knowles drivers like the ED and SWFK series in high-fidelity in-ear monitors.

Replacement Considerations

Direct substitutes are not publicly listed. Equivalent performance may require custom-tuned alternatives from other manufacturers such as Sonion or Seigohki, but acoustic matching must be verified through prototyping.
