SPS-BD MICROPHONE

HP 821696-001 dual-array microphone module is a replacement microphone component for compatible HP laptops. Its dual-array design provides the computer with a microphone module for voice input during everyday communication and recording tasks.

The part is listed for models including the HP EliteBook 820 G3 and 828 G3. In the EliteBook 820 G3 service guide, the microphone module is identified as a separate display-assembly component, distinct from the webcam module. This helps identify the part when replacing a microphone module rather than a combined camera assembly.

The service procedure describes the module as attached to the display enclosure with double-sided tape and connected by a cable. The documented installation location and cable connection make it a laptop display assembly component, rather than a stand-alone desktop microphone.
