SPS-SPEAKERS

HP speaker assembly 828420-001 is a replacement speaker unit for supported HP notebook computers. It connects to the system board by a speaker cable and sits in the computer’s top cover, making it a service part for restoring the built-in speaker hardware.

HP’s service guide identifies this assembly by its exact spare part number and describes the speakers as removable from the top cover. This makes the part relevant when servicing the speaker assembly in a compatible notebook.

A distributor lists it for the HP ProBook 450 G3 and HP ProBook 455 G3 Notebook PCs. The listing and HP service documentation together confirm the part identity and its intended role; they do not specify audio power, speaker dimensions or package contents.
