EJ-23080-000

Speakers Overview

The Knowles EJ-23080-000 is a miniature speaker designed for audio output applications. It features an impedance of 380 ohms and utilizes a side port configuration with a sensitivity rating of 110 dB. The physical dimensions are specified as 6.33 mm in length, 4.32 mm in width, and 5.97 mm in height. This component is part of the Knowles audio device portfolio, offering a compact form factor suitable for space-constrained electronic designs requiring reliable sound reproduction.

Speakers Feature Summary

• Compact mechanical design with precise dimensional constraints for integration into small enclosures
• Side port acoustic architecture to direct sound output effectively
• High impedance specification of 380 ohms for specific driver matching requirements

Speakers Applications

• Portable consumer electronics requiring miniaturized audio output
• Medical devices needing compact sound generation components
• Industrial control panels with limited internal volume

Speakers Procurement Notes

Verify the exact port orientation (side vs. top) and sensitivity variant against the official datasheet before ordering, as multiple configurations exist within this series. Confirm RoHS compliance status and lead-free manufacturing details with the supplier. Ensure the 380-ohm impedance matches your circuit design requirements. Request the latest revision of the technical drawing to verify pinout and mounting hole specifications for PCB layout compatibility.

Speakers Selection Notes

Select this model when a high-impedance, low-power speaker is required for space-limited applications. The 380-ohm impedance suggests suitability for specific amplifier outputs or voltage-driven circuits rather than standard low-impedance systems. Evaluate the 110 dB sensitivity against the required acoustic output level and available drive voltage. Consider the side port direction relative to the enclosure opening to ensure optimal sound projection and minimal obstruction.

Speakers Part Context

This component belongs to the Knowles miniature speaker family, which focuses on providing high-quality audio solutions in ultra-small packages. The EJ series typically targets applications where size and weight are critical factors. Knowles leverages its expertise in acoustic engineering to deliver consistent performance across various industrial and consumer sectors. These speakers often feature robust construction to withstand environmental stresses while maintaining acoustic integrity.

Speakers Replacement Considerations

Direct substitutes must match the 380-ohm impedance, 110 dB sensitivity, and 6.33 x 4.32 x 5.97 mm footprint. Verify that any replacement maintains the side port configuration or adjust the enclosure design if a top-port variant is used. Ensure the new component meets the same electrical and mechanical specifications to avoid redesigning the host device.
