High sensitivity rating for efficient audio output

Speakers Applications

Behind-the-ear (BTE) hearing aids
In-the-canal (ITC) hearing aids
Hearing aid receiver modules

Speakers Procurement Notes

Verify the specific acoustic performance requirements against the datasheet specifications before procurement. Confirm that the rectangular package dimensions and top port orientation match the target device enclosure constraints. Ensure compatibility with the intended hearing aid platform architecture.

Speakers Selection Notes

Select this component when a compact rectangular receiver is required for BTE or ITC hearing aid designs. Consider the 110 Ohm impedance and 126 dB sensitivity for power efficiency and volume needs. Evaluate the 200 Hz to 6.3 kHz bandwidth against speech clarity requirements.

Speakers Part Context

This part belongs to the Knowles receiver speaker portfolio, specifically engineered for medical auditory devices. It represents a specialized transducer solution distinct from general-purpose audio speakers, focusing on miniaturization and reliability within strict size limitations typical of modern hearing instruments.

Speakers Replacement Considerations
