Planar Speaker For Multimedia Laptop Pcs

View page
US Patent:
6760456, Jul 6, 2004
Filed:
Oct 5, 2000
Appl. No.:
09/684556
Inventors:
Marco Annaratone - Menlo Park CA
Assignee:
Hewlett-Packard Development Company L.P. - Houston TX
International Classification:
H04R 2500
US Classification:
381306, 381333, 381388, 381386, 361683
Abstract:
A portable computer system with planar speakers. The planar speakers are fabricated with a coplanar array of small, low cost, durable, electromagnetic speaker elements mounted on a panel. The planar speakers can be attached to the lid of the computer system. The planar speakers can slide into a compartment in the lid of the computer system when not in use and slide out of the compartment for use with greater physical separation than that of built-in speakers. Alternatively, the planar speakers are attached to the lid via a hinge and folded against the lid when not in use. The planar speakers are folded outward extending the planar speakers beyond the lid for use with greater physical separation than that of built-in speakers. The planar speakers can be detachable from the remainder of the computer system for greater spacing and variable positioning of the planar speakers for improved stereo sound reproduction. Detached planar speakers also permit transport or storage of the planar speakers separately from the remainder of the computer system.
