Speakers Procurement Notes

Verify the specific revision code and packaging format directly with the manufacturer or authorized distributors before ordering. Ensure that the procurement documentation explicitly confirms the component matches the ES-23140-000 designation to avoid substitution errors. Confirm compliance requirements and material declarations align with project specifications. Request official datasheets to validate electrical and mechanical tolerances against design inputs.

Speakers Selection Notes

Select this component when a rectangular balanced armature speaker is required for applications demanding a 101 dB sensitivity and a frequency response extending up to 5.9 kHz. The 5.18 mm x 3.55 mm footprint makes it suitable for designs where standard circular receivers do not fit. Evaluate the impedance characteristics against the driving circuitry to ensure adequate power handling and signal integrity within the target audio bandwidth.

Speakers Part Context

This part belongs to the Knowles ES series of balanced armature speakers. The series is characterized by its use in miniaturized audio solutions where size and acoustic performance are critical. The ES-23140-000 specifically addresses the need for rectangular form factors in modern consumer electronics, distinguishing itself from traditional round receiver designs while maintaining high efficiency and clarity.

Speakers Replacement Considerations

Cross-reference with other rectangular balanced armature models from the same manufacturer family. Verify that any substitute maintains identical mounting dimensions and terminal configurations. Ensure the replacement part meets or exceeds the original 101 dB SPL and frequency range specifications. Confirm compatibility with existing acoustic chambers and sealing requirements.
