Speakers datasheet and documents for EF-28395-055

EF-28395-055

Speakers Overview

The EF-28395-055 is a speaker transducer manufactured by Knowles. It features an impedance of 74 ohms and includes a port located on the end of the housing. The physical dimensions are 7.87 mm in length, 5.59 mm in width, and 4.01 mm in height. The sensitivity rating is specified as 126 dB.

Speakers Feature Summary

Integrated acoustic port positioned on the end of the unit
Defined impedance characteristic of 74 ohms
Compact rectangular form factor suitable for constrained spaces

Speakers Applications

Audio signal reproduction in compact electronic devices
Transducer applications requiring specific end-port acoustics
Embedded sound generation systems

Speakers Procurement Notes

Verify the specific acoustic requirements against the 74-ohm impedance and 126 dB sensitivity specifications before procurement. Confirm that the end-port configuration aligns with the mechanical design constraints of the target enclosure. Ensure the manufacturer designation matches Knowles to guarantee component authenticity and performance consistency.

Speakers Selection Notes

Select this component when a small form factor with integrated end-porting is required. The 74-ohm impedance must match the driving circuit capabilities. Consider the 126 dB sensitivity level for volume requirements within the available space constraints defined by the 7.87 x 5.59 x 4.01 mm dimensions.

Speakers Part Context

This part belongs to the EF series of speakers from Knowles. It is categorized under speakers and transducers. The product line focuses on providing audio solutions with specific acoustic geometries, such as the end-port design found in this model.

Speakers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing mounting structures and electrical driving requirements if considering alternative transducers.
