  • Patent number: 5852545
    Abstract: A computer system has a data processing unit, an audio speaker assembly apparatus, and at least one computer component mounting structure. The audio speaker assembly apparatus includes one or more speakers and one or more mounting mechanisms for electrically and mechanically connecting each speaker to the computer component mounting structure. Each speaker may be selectively and detachably connected to the computer component mounting structure so both an electrical connection of a speaker to the mounting structure and a physical support of the same speaker to the mounting structure can be readily established or removed. The computer component mounting structure may be, for example, as LCD housing or another type of display housing, or it may be a stationary mounting structure such as a docking station for docking portable notebook computers.
