DWFK-31785-B75

Speakers Overview

The Knowles DWFK-31785-B75 is a balanced armature driver designed for in-ear monitor applications. It features a small form factor and high efficiency relative to its size. The acoustic tuning is characterized as more bass-oriented compared to the TWFK series, providing enhanced low-frequency response within a compact receiver package.

Speakers Feature Summary

• Balanced armature transducer technology
• Bass-oriented acoustic tuning profile
• High sound pressure level per unit volume

Speakers Applications

• In-ear monitor receivers
• Custom in-ear headphones
• Professional audio monitoring equipment

Speakers Procurement Notes

Verify the specific suffix B75 against the official Knowles datasheet to confirm terminal configuration and acoustic tolerances. Ensure compatibility with existing earphone housings and crossover networks. Confirm RoHS compliance status through current manufacturer documentation before integration into final assemblies.

Speakers Selection Notes

Select this component when a compact driver with emphasized bass response is required for custom IEM designs. Compare performance metrics against the TWFK series if neutral tonal balance is preferred over bass enhancement. Validate mechanical fitment within the target earpiece shell dimensions prior to procurement.

Speakers Part Context

This model belongs to the Knowles balanced armature family, specifically engineered for high-fidelity audio reproduction in constrained spaces. The DWFK series utilizes advanced magnetic structures to optimize output efficiency while maintaining miniaturization standards essential for modern wearable audio devices.

Speakers Replacement Considerations

Cross-reference with the TWFK series for alternative tonal characteristics. Verify pinout compatibility and impedance matching when substituting similar balanced armature drivers from the same manufacturer or other approved suppliers.
