Speakers Procurement Notes

Verify the specific manufacturer part number against official Knowles documentation to ensure authenticity. Confirm that the component meets all required electrical specifications, including impedance and frequency response, for the intended application. Check for RoHS compliance status as indicated in the datasheet. Ensure proper handling procedures are followed during assembly due to the delicate nature of balanced armature transducers.

Speakers Selection Notes

Select this component when high sensitivity and compact size are critical requirements. The balanced armature design offers superior performance in small enclosures compared to dynamic drivers. Consider the 53 Ohm impedance for matching with amplifier outputs. Evaluate the 100Hz to 5.5kHz frequency range against the target audio spectrum needs. The rectangular shape facilitates integration into tight spaces typical of wearable audio devices.

Speakers Part Context

This model belongs to Knowles' portfolio of precision audio components. Balanced armature receivers are specialized transducers known for their efficiency and accuracy in low-power applications. They are distinct from dynamic speakers and are commonly used in medical and hearing assistance devices where miniaturization and performance are paramount.

Speakers Replacement Considerations

Consult official Knowles documentation for verified substitute part numbers. Ensure any replacement matches the original impedance, frequency response, and physical dimensions. Verify compatibility with existing circuit designs and housing constraints before substitution.
