Speakers datasheet and documents for ED-31197-163
Speakers Overview
The Knowles ED-31197-163 is a balanced armature speaker designed for high-power hearing aid applications. It features a medium direct current resistance to impedance ratio, providing efficient power handling within a compact form factor comparable to an EF receiver size. This component utilizes electromagnetic technology to deliver precise audio reproduction in space-constrained environments.
Speakers Feature Summary
- Enables high-fidelity sound reproduction in space-constrained hearing aids
- Reduces distortion and feedback for clearer audio experiences
- Supports a medium direct current resistance to impedance ratio
Speakers Applications
- High-power hearing aids
- Space-constrained audio devices requiring balanced armature drivers
- Premium sound applications needing reduced distortion
Speakers Procurement Notes
Verify the specific datasheet version when sourcing, as Knowles may update technical documentation over time. Confirm that the received components match the ED-31197-163 designation exactly. Ensure storage conditions comply with manufacturer guidelines for sensitive electronic transducers to maintain performance integrity before assembly.
Speakers Selection Notes
Select this model when a compact driver similar in size to an EF receiver is required but higher power handling is necessary. The medium DCR to impedance ratio makes it suitable for applications where electrical efficiency and acoustic output must be balanced within tight physical constraints typical of modern hearing aid designs.
Speakers Part Context
This component belongs to the Knowles TEC Balanced Armature Speakers family, which focuses on premium sound quality. It is categorized under Receivers and Transducers, specifically utilizing balanced armature technology rather than dynamic drivers. The series is engineered for specialized audio applications demanding high fidelity in small packages.
Speakers Replacement Considerations
Consider drivers with similar EF-sized footprints if spatial constraints are critical. Verify that substitute parts support comparable power handling capabilities and maintain the medium DCR to impedance ratio characteristics essential for the original circuit design.
