• Wearable audio devices

Speakers Procurement Notes

Verify the specific port configuration (top vs. side) against the official datasheet, as variations exist within the EC series. Confirm impedance matching requirements for the target application circuit. Ensure compliance with RoHS standards if required by the end product specifications. Cross-reference the part number with the manufacturer's latest documentation to confirm current availability and manufacturing status.

Speakers Selection Notes

Select this component when high sensitivity and compact size are critical. The 400-ohm impedance requires appropriate driver circuitry compared to standard 8-ohm speakers. Consider the 200 Hz to 4 kHz frequency response limitations for applications requiring deep bass or ultrasonic frequencies. Evaluate the mechanical mounting options provided by the package style for reliable assembly.

Speakers Part Context

This part belongs to the Knowles EC Series of speakers, which are specialized acoustic components often used in medical and hearing aid applications. The series is characterized by its balanced armature technology, offering superior performance in small packages compared to dynamic drivers. These components are engineered for reliability and consistent acoustic performance in demanding environments.

Speakers Replacement Considerations

Direct substitutes may include other models from the Knowles EC series with similar impedance and dimensions. Verify compatibility with existing acoustic chambers and mounting structures. Alternative brands may require significant redesign of the audio path due to differences in sensitivity and frequency response characteristics.
