HP 636925-001 internal speaker is a replacement speaker unit for the inside of a desktop computer chassis. HP identifies this exact part number as an internal speaker in its service documentation.
The speaker sits at the front of the chassis, beneath the rotating drive cage. Its wire connects to the system board connector marked SPKR, and a screw holds the unit in place. This layout describes how the part is mounted and connected within the computer.
During removal, the speaker lifts out from inside the chassis after its wire and securing screw are disconnected. The part is intended for an internal speaker position, rather than as a standalone external speaker.
