Speakers Procurement Notes

Verify the specific datasheet version for the EH-23044-000 to confirm current RoHS compliance status and detailed mechanical tolerances. Ensure that the top-port orientation aligns with the acoustic design requirements of the target enclosure. Cross-reference the impedance value with the driving circuit specifications to guarantee optimal power transfer and signal integrity during integration.

Speakers Selection Notes

Select this component when a high-efficiency, low-profile speaker is required for hearing aid or premium audio applications. The 1.055 kOhm impedance suits specific driver circuits, while the 103 dBA efficiency ensures adequate volume in small enclosures. Consider the 3.05 mm height constraint and rectangular footprint when evaluating PCB layout and housing compatibility against alternative balanced armature drivers.

Speakers Part Context

This part belongs to Knowles' portfolio of balanced armature receivers, which are engineered for high-fidelity audio reproduction in miniature sizes. The EH series typically targets medical and consumer audio markets where size and weight are critical constraints. These components utilize magnetic transduction principles optimized for clarity and power efficiency in portable electronics.

Speakers Replacement Considerations

Check for direct substitutes within the EH series or compatible Knowles balanced armature lines. Verify that any replacement matches the 1.055 kOhm impedance and 103 dBA efficiency to maintain acoustic performance. Ensure the physical dimensions and port location are identical to avoid redesigning the acoustic chamber.
