Overview
The Knowles BK-21612-052 is a balanced armature speaker transducer designed for compact audio applications. It features a nominal impedance of 500 ohms and includes a sound port located on the end of the housing. The component utilizes stainless steel construction to ensure durability in demanding environments. This specific model is categorized under speakers and transducers, offering a specialized acoustic output suitable for devices requiring precise signal reproduction within limited physical spaces.
Feature Summary
- Balanced armature technology for efficient audio conversion
- Stainless steel housing for structural integrity
- End-mounted sound port configuration
Applications
- Compact consumer electronics audio output
- Medical device acoustic signaling
- Industrial control panel feedback systems
Procurement Notes
Verify the exact impedance specification of 500 ohms against circuit requirements before integration. Confirm that the end-port orientation aligns with the mechanical design constraints of the target enclosure. Ensure compatibility with driving circuits capable of handling high-impedance loads typical of balanced armature speakers. Cross-reference the stainless steel material properties if environmental resistance is critical.
Selection Notes
Select this component when high impedance matching is required for specific driver outputs. Consider the stainless steel build for applications needing enhanced corrosion or wear resistance compared to standard polymer housings. Evaluate the end-port layout against available space for acoustic venting. Balance the higher impedance against power consumption needs in battery-operated devices.
Part Context
This part belongs to the Knowles speakers and transducers family, specifically focusing on balanced armature designs. It complements other models like the BK-21612-B48 which offers different impedance characteristics. The series provides various options for integrating audio functionality into small form-factor devices while maintaining reliable performance standards.
Replacement Considerations
Direct substitutes may include other Knowles balanced armature speakers with similar 500-ohm impedance ratings. Models such as those in the CDM series might offer comparable form factors but require verification of acoustic parameters. Always validate electrical and mechanical fit before swapping components.
