Abstract

This invention minimizes the space required for a speaker system for a multimedia personal computer display on a desktop. The speaker system has a very thin shape, moderate cost, very good impulse and phase response for a crisp sonic detail and good directionality for use by a single listener seated in front of the multimedia personal computer display without disturbing others nearby. Each component of the speaker system is attached to or incorporated in the right or left side of the computer display. Each component comprises a plurality of small speakers arranged in a vertical, linear array. Preferably, each plurality includes a small folded waveguide which is acoustically coupled to the rear of each of the speakers. The folded waveguide is in a unique sheet configuration and enables directional ports in a treble component and a folded variable impedance maze in a base waveguide. The speaker system provides the required shape, clarity and listener isolation needed in the personal multimedia market. A locator function is provided by the speaker system to locate the listener to enable stereo effects such as sonic holography.
