Title:
CONCRETE RESONANT CONE SPEAKER SYSTEM
United States Patent 3750838
Abstract:
A speaker system for use in conjunction with a high fidelity system, the speaker system being placed within a room, and including a vertically upstanding truncated cone of hollow character and which tapers upwardly toward a top opening, the lower end of the concrete cone being mounted upon a wood base that supports a speaker, the wood base including a top ring, intermediate ring and flat bottom piece surrounding the speaker, the top ring, intermediate ring and bottom piece being spaced apart by means of the support separators.

Claims:
What I now claim is
1. In a concrete resonant cone speaker system, the combination of a wood base for placement upon the floor of a room, and a vertically upstanding concrete truncated cone placed upon said wood base, said wood base containing a speaker in alignment with a lower end of said concrete truncated cone for moving sound waves upwardly through said concrete truncated cone so as to give a false depth to a room without an espensive reverberation unit and delay system, wherein said concrete truncated cone comprises a one piece member made of concrete drainage tile, said concrete truncated cone consisting of a conical side wall around a central opening extending there through, said concrete truncated cone supported upon said wood base being tapered upwardly toward a smaller end at its top, and wherein said wood base consists of a circular bottom piece, an intermediate ring in spaced relation above said bottom piece and a top ring in spaced relation above said intermediate ring, said rings and bottom piece having a plurality of support separators there between, and said speaker being secured to an under side of said top ring.

Description:
This invention relates generally to sound speaking systems.
A principal object of the present invention is to provide a concrete resonant cone speaker system which gives a false dpeth to a room without an expensive reverberation unit and delay system.
Another object of the present invention is to provide a concrete resonant cone speaker system wherein the delay is accomplished by the time factor required for a sound wave to travel up the concrete cone and bounce off of the ceiling and reach a listener.
Yet a further object of the present invention is to provide a concrete resonant cone speaker system wherein a choking effect of the sound wave occurs as the sound wave travels up the concrete cone, because of the slightly conical shape thereof, much the same as a choke of a shotgun, which helps to prevent the sound wave from spreading before it reaches the ceiling.
Yet a further object of the present invention is to provide a concrete resonant cone speaker system wherein the unit has a 360° sound spread from the base (nondelayed sound) and the sound projecting off of the ceiling.
Other objects of the present invention are to provide a concrete resonant cone speaker system which is simple in design, inexpensive to manufacture, rugged in construction, easy to use and efficient in operation.
These and other obejects will be readily evident upon a study of the following specification and the accomapnying drawing wherein:
FIG. 1 is a side elevation view of the present invention shown partly in cross-section, and
FIG. 2 is a cross sectional view taken on the line 2--2 of FIG. 1.
Referring now to the drawing in detail, the reference numeral 10 represents a concrete resonant cone speaker system according to the present invention wherein there is a concrete cone 11 made of concrete drainage tile and which comprises a conical side wall around a central opening 12 extending through the truncated cone. The concrete truncated cone is placed upon a wood base 13 and extends vertically upwardly with the tapered end of the truncated cone being at the top.
The wood base 13 supports a speaker 14 located on the vertical axis of the concrete truncated cone so that sound from the speaker is directed into the interior 12 of cone 11. The wood base 13 is comprised of a circular flat bottom piece 15, intermediate ring 16, top ring 17 and a plurality of support separators. A plurality of four support separators 18 are placed between the bottom piece 15 and the intermediate ring 16 while another set of four support separators 19 are placed between the intermediate ring 16 and the top ring 17, it being noted particularly in FIG. 2 that the support separators 18 and 19 are out of alignment with each other. A circular support separator 20 of ring shape is fitted within the lower end of central opening 12, the support separator 20 being secured upon the top ring 17 concentrically therewith. The speaker 14 is secured to the underside of the top ring 17.
In operative use the hollow tile may contain a tuned resonant column of air. The base is especially designed to isolate the concrete drainage tile from the floor so that it will not be damped by contact with the floor. The support separators 18 and 19 are strategically placed between the rings and the bottom piece in disaligned position as indicated. This isolates the concrete tile much the same way as the tines on a tuning fork are isolated.
There is a 360° low level, linear delay off of the side of the drainage tile, as the sound wave travels up the tile. The lip on the top ring supports separator 20 is fitted into the lower end of the concrete truncated cone. Wood screws are used to secure the speaker to the bottom of the top ring. Wood screws are used to secure the top ring to the support separators and they are also counter sunk to keep them from interfering with the lip of the concrete drainage tile when it is set on top of the base.
