CI-22960-000

Overview

The Knowles CI-22960-000 is a subminiature balanced armature receiver designed for high-efficiency audio applications. It features a rectangular top port configuration and operates within a frequency range of 200 Hz to 5.5 kHz. The device delivers a sound pressure level of 127 dBA at 500 Hz with an impedance of 264 Ohms. Physical dimensions include a depth of 4.19 mm, supporting panel mount installation in compact electronic devices requiring reliable acoustic output.

Feature Summary

• Balanced armature technology ensures high efficiency and operational stability
• Rectangular top port design facilitates precise acoustic directionality
• Subminiature form factor enables integration into space-constrained assemblies

Applications

• Hearing aids and assistive listening devices
• Medical diagnostic equipment speakers
• Industrial communication headsets
• Compact consumer electronics receivers

Procurement Notes

Verify component authenticity through authorized Knowles distributors or certified supply chain partners. Request original manufacturer datasheets and test reports to confirm electrical parameters match the specified 264 Ohm impedance and 127 dBA sensitivity. Ensure storage conditions comply with moisture sensitivity levels to prevent package degradation prior to assembly.

Selection Notes

Evaluate the 200 Hz to 5.5 kHz frequency response against target application bandwidth requirements. Confirm mechanical compatibility with the 4.19 mm depth constraint and panel mounting interface. Assess acoustic performance needs relative to the 127 dBA output capability to ensure adequate signal clarity without distortion in the intended operating environment.

Part Context

This component belongs to the Knowles CI series of subminiature speakers, which utilize balanced armature transduction methods. The series is engineered for applications demanding high reliability and consistent acoustic performance in small form factors. These receivers are distinct from dynamic drivers, offering superior efficiency and linearity for voice reproduction tasks.

Replacement Considerations

Cross-reference compatible models such as the CI-22960-P29 for similar balanced armature specifications. Verify that substitute parts maintain identical impedance, frequency response, and physical mounting dimensions to ensure seamless integration without redesigning the acoustic chamber or circuit board layout.
