Overview
The Knowles CI-22955-017 is a balanced armature speaker transducer designed for high-fidelity audio applications. It features an impedance of 20 ohms with the port located on the end, facilitating integration into compact acoustic assemblies. This component is engineered to deliver robust bass response and low distortion, leveraging a diaphragm size larger than typical balanced armature drivers. Its construction supports precise sound reproduction in demanding environments such as in-ear monitors.
Feature Summary
- Balanced armature design optimized for low-distortion bass performance
- End-port configuration simplifies acoustic assembly integration
- High-transparency resin compatibility for medical-grade shell applications
Applications
- In-ear monitor bass driver units
- Professional audio monitoring systems
- Medical-grade hearing assistance devices
Procurement Notes
Verify the specific suffix (e.g., -017) against official Knowles documentation to ensure correct impedance and port orientation. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to ordering. Ensure acoustic housing designs accommodate the end-port specification for optimal performance.
Selection Notes
Select this model when a dedicated bass driver with higher excursion capability is required within a multi-driver balanced armature array. The 20-ohm impedance suits specific crossover networks. Consider its use in applications requiring medically certified materials for the surrounding shell structure, ensuring compatibility with the driver's acoustic output requirements.
Part Context
This component belongs to the Knowles CI series of balanced armature speakers. It is specifically utilized as a bass driver in quad balanced armature configurations, such as those found in the FiiO FA7 in-ear monitors. The part works in conjunction with mid-range and treble balanced armature drivers to provide a full frequency range response.
Replacement Considerations
Direct substitutes include other CI-series balanced armature drivers with similar impedance and porting, such as the CI-22955-M11. Verify mechanical dimensions and acoustic tuning before substitution.
