Speakers Procurement Notes

Verify the specific ordering suffix and packaging configuration against the official Knowles datasheet before procurement. Ensure compatibility with existing acoustic chambers and mounting structures. Confirm that the 46.3 Ohm impedance aligns with the target amplifier or driver circuit requirements. Check for any recent revisions to the mechanical dimensions to guarantee proper fit within the device enclosure.

Speakers Selection Notes

Select this component when a small footprint balanced armature driver with high sensitivity is required. The 46.3 Ohm impedance suits circuits designed for this specific load. Consider the 80 Hz to 10.8 kHz frequency range to ensure it covers the necessary audio spectrum for the application. Evaluate the 116 dBA SPL to confirm adequate volume levels for the intended use case without excessive power consumption.

Speakers Part Context

This part belongs to the Knowles RAB series of balanced armature drivers. These components are widely used in the audio industry for their ability to deliver high fidelity sound in miniature packages. The RAB series is specifically engineered for applications where space is limited but performance standards remain high, such as in modern hearing aids and high-end audio accessories.

Speakers Replacement Considerations

Consult the official Knowles documentation for direct cross-references. Verify that any substitute maintains the same 46.3 Ohm impedance and similar frequency response characteristics. Mechanical compatibility must be confirmed by comparing pin configurations and overall dimensions.
