EJ-26552-000

Speakers Overview

The Knowles EJ-26552-000 is a rectangular balanced armature receiver designed for the speaker side of audio applications. It features a compact physical footprint measuring 6.33 mm in length, 4.32 mm in width, and 5.97 mm in height. The component provides a sound pressure level sensitivity of 110 dB and utilizes a 12-second port configuration to optimize acoustic performance.

Speakers Feature Summary

• Rectangular balanced armature design optimized for speaker-side integration
• High sensitivity output for efficient audio reproduction
• Compact form factor suitable for space-constrained devices

Speakers Applications

• Receiver modules in mobile communication devices
• Speaker-side audio components in portable electronics
• Integrated audio systems requiring high-sensitivity transducers

Speakers Procurement Notes

Verify the specific datasheet version to confirm mechanical tolerances and acoustic specifications match your design requirements. Ensure compatibility with existing enclosure designs given the precise 6.33 x 4.32 x 5.97 mm dimensions. Confirm that the 12S port configuration aligns with your target frequency response and sound profile needs before finalizing procurement.

Speakers Selection Notes

Select this component when a rectangular balanced armature receiver is required for the speaker side of an audio chain. The 110 dB sensitivity makes it suitable for applications demanding high efficiency. Consider the physical constraints of the 6.33 x 4.32 x 5.97 mm package size during the layout phase to ensure proper fit within the device housing.

Speakers Part Context

This part belongs to Knowles' portfolio of balanced armature transducers, which are widely used in hearing aids, earpieces, and other small audio devices. The EJ series specifically targets applications where rectangular footprints offer assembly advantages over circular designs. These components are engineered for consistent acoustic performance across various consumer electronics platforms.

Speakers Replacement Considerations

Direct substitutes must match the rectangular balanced armature type, similar sensitivity around 110 dB, and comparable physical dimensions. Verify that any alternative maintains the 12S port specification to preserve intended acoustic characteristics. Consult manufacturer cross-reference lists for validated equivalents.
