The sound speaker system comprises an elongated vertical cylinder having an overall length equal to an integral multiple of its inside diameter. The cylinder is open at its upper and lower ends and a loudspeaker is positioned adjacent its lower end. The diameter of the loudspeaker cone is equal to one-half the inside diameter of the cylinder. The system is designed to be placed in the corner of a room so that sound emanating from the lower and upper ends is reflected by the floor and ceiling corners respectively into the room.

This invention relates generally to sound and more particularly to an improved sound speaker system for enhancing the enjoyment of music and the like.
The prior art is prolific with respect to various types of loudspeaker designs for use in music systems. Known speaker systems range from extremely compact type speakers within baffled cabinets to fairly large rectangular-shaped speaker cabinets incorporating one or more loudspeakers.
Most speakers of the foregoing type, particularly sophisticated versions, are relatively expensive. Further, while the baffling in such speakers is theoretically based on computations of wave lengths so as to enhance certain frequencies in the sound spectrum, there generally are provided many speakers in a single cabinet in order to properly cover this spectrum. For example, relatively large speakers are provided to enhance bass tones while smaller or "tweeter" type speakers are used for the higher frequencies. In addition to the expense of multiple speakers per se in a given cabinet structure, when more than one speaker is used, impedance matching problems arise and thus further expense is involved in assuring maximum power transfer between the output from an amplifier and the input to the speaker system.
A better understanding of the invention will be had by now referring to the accompanying drawings in which:
FIG. 1 is a perspective view of the preferred embodiment of the sound speaker system shown disposed in the corner of a room;
FIG. 2 is an exploded perspective view of the basic components making up the sound speaker system of FIG. 1;
Referring first to FIG. 1, there is shown an elongated vertical cylinder 10 having upper and lower open ends 11 and 12. In the particular embodiment illustrated in FIG. 1 there is provided a secondary cylinder 13 telescopically receiving the lower open end 12 of the cylinder 10. A base stand includes a flat horizontal circular surface 14 supporting the lower end of the secondary cylinder 13 and including legs 15 secured to its underside.
As indicated by the dotted lines in FIG. 1, the flat surface 14 of the base stand includes a central opening 16 over which is positioned a loudspeaker 17. Speaker wires for the speaker 17 extend through an auxiliary opening in the flat surface 14 from the lower portion of the base stand as indicated at 18.
The basic structure is completed by the provision of stop means 19 three of which are indicated by the dotted lines serving to support the inner telescoped lower end of the elongated cylinder 10 in a given telescoped position with respect to the secondary cylinder 13. These stop means can be removed so that the elongated cylinder 10 can telescope completely within the secondary cylinder 13 to rest on the surface 14. This latter situation is depicted by the dotted lines wherein the upper open end of the elongated cylinder 10 is indicated at 11'.
