Speakers Feature Summary

• Rectangular balanced armature design optimized for space-constrained enclosures
• Electromagnetic transduction technology for accurate audio reproduction
• Receiver configuration tailored for personal audio and medical hearing devices

Speakers Applications

• Hearing aids
• Earphones
• Compact audio receivers

Speakers Procurement Notes

Verify the specific acoustic impedance and sensitivity ratings against the official Knowles datasheet before integration, as these parameters are critical for matching with driver circuits. Confirm that the rectangular form factor aligns with the mechanical housing constraints of the target device to ensure proper fit and acoustic sealing.

Speakers Selection Notes

Select this component when a rectangular footprint is required for balanced armature drivers in miniaturized audio systems. It is appropriate for designs prioritizing high fidelity within tight spatial limits, such as modern hearing aids or slim-profile earbuds, where standard round drivers cannot be accommodated.

Speakers Part Context

This part belongs to Knowles' portfolio of specialty audio components, specifically their balanced armature receiver line. These components are engineered for high performance in medical and consumer audio sectors, leveraging Knowles' expertise in precision micro-acoustics and electromagnetic design for reliable operation in sensitive environments.

Speakers Replacement Considerations

Direct substitutes must match the rectangular geometry and balanced armature architecture. Verify equivalent acoustic power handling and frequency response characteristics to maintain system performance without redesigning the acoustic chamber.
