    Abstract: A planar speaker for an information handling system includes a frame, a voice coil, a speaker cone, a primary surround damper, and a secondary surround damper. An outside edge of the primary surround damper is affixed to a first surface of the frame, and an inside edge of the primary surround damper is affixed to the cone. An outside edge of the secondary surround damper is affixed to a second surface of the frame, and an inside edge of the secondary surround damper is affixed to a portion of the voice coil.

    Abstract: An electronic device may be provided with peripheral conductive housing structures having a segment that forms a resonating element for an antenna. A speaker may be mounted to a mid-chassis of the electronic device. A printed circuit may be mounted to the speaker and may have a ground trace for the antenna. A conductive spring may extend through the printed circuit and the speaker to couple the ground trace to the mid-chassis. A conductive contact pad may be welded to an aluminum layer such as an aluminum layer used to form the mid-chassis. A conductive spring such as the conductive spring coupled to the ground traces may press against the contact pad. The contact pad may include gold or nickel-plated stainless steel. The contact pad may provide a strong electrical connection between the conductive spring and the aluminum layer.
