BK-21613-033

Overview

The Knowles BK-21613-033 is a receiver speaker transducer designed for compact audio applications. It features a nominal impedance of 160 ohms and includes a side port configuration to optimize acoustic performance in constrained spaces. The component is engineered to deliver high-fidelity sound reproduction while minimizing distortion and feedback, making it suitable for hearing aids and similar devices requiring clear audio output.

Feature Summary

Enables high-fidelity sound reproduction in space-constrained hearing aids
Reduces distortion and feedback for clearer audio experiences

Applications

Hearing aids
Compact audio receivers
Medical audio devices

Procurement Notes

Verify the specific acoustic requirements against the 160-ohm impedance specification. Confirm that the side port design aligns with the enclosure constraints of the target application. Ensure compatibility with the intended driving circuitry for optimal performance.

Selection Notes

Select this component when high fidelity and low distortion are critical within limited physical dimensions. The 160-ohm impedance requires matching with appropriate amplification stages. Consider the side port orientation during mechanical integration to ensure proper acoustic coupling.

Part Context

This receiver belongs to Knowles' portfolio of specialized audio transducers. It is distinct from general-purpose speakers due to its optimized design for hearing aid form factors. The technology focuses on balancing acoustic clarity with miniaturization needs typical of medical wearable devices.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify electrical and mechanical compatibility before considering alternative components.
