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. |

DETAILED DESCRIPTION OF THE DRAWINGS The invention can be incorporated in the display of a variety of computers.
The processor unit could be, for example, a personal computer, a mini computer or a mainframe computer, running the plurality of computer displays.
The computer may be a standalone system, part of a network, such as a local area network or wide are network or a larger teleprocessing system.
Most preferably, however, the invention as described below is implemented on a standalone multimedia personal computer, such as IBM's PS/2 multimedia series, although the specific choice of a computer is limited only by the resource requirements, e.
g.
, memory and disk storage of multimedia programming.
For additional information on IBM's PS/2 series of computer readers referred to Technical Reference Manual Personal System/2 Model 50, 60 Systems and (IBM Corporation, Part Number 68X2224, Order Number S68X-2224 and Technical Reference Manual, Personal System/2(Model 80) IBM Corporation, Part Number 68X22256, Order Number S68X2256.
In FIG.
1, a personal computer 10, comprising a system unit 11, keyboard 12, a mouse 13 and a display 14 are depicted.
Also depicted are the speaker systems 15a and 15b mounted to the left and right of the monitor 14.
The screen 16 of display device 14 is used to present the visual components multimedia presentation.
The speaker system 15a and 15b provides good quality sound with very good impulse and phase response with good directionality for the single listener without disturbing others nearby.
Note that the very thin shape of the speaker system requires a minimum of additional desk space beyond that which would ordinarily be required by the display 14 itself.
FIG.
2 shows a block diagram of the components of the multimedia personal computer shown in FIG.
1.
The system unit 11 includes a system bus to which various components are coupled and by which communication between the various components is accomplished.
A microprocessor 22 is connected to the system bus 21 and is supported by read only memory (ROM) 23 and random access memory (RAM) and (24) also connected to system bus 21
