Speakers Procurement Notes
Verify the specific revision suffix against official Knowles documentation to ensure compatibility with target device acoustics. Confirm that the 92-ohm impedance and 104 dB sensitivity meet system requirements. Request CAD models for mechanical integration checks prior to procurement.
Speakers Selection Notes
Select this component when high-fidelity sound reproduction is required within strict spatial constraints typical of hearing aids. Evaluate the 200 Hz to 3.5 kHz bandwidth against user hearing profiles. Ensure the 105 dB to 132 dB SPL range aligns with the necessary gain specifications for the intended application.
Speakers Part Context
This part belongs to Knowles' portfolio of micro-speakers and transducers specialized for medical and consumer audio. It utilizes balanced armature architecture, which offers superior efficiency and size-to-performance ratios compared to traditional dynamic drivers in miniature applications.
Speakers Replacement Considerations
Cross-reference with other Knowles balanced armature receivers such as the BK-21612-B48 series. Verify that substitute parts match the 92-ohm impedance and similar frequency response curves to maintain acoustic consistency.
