Abstract

The device relates to a circular electronic musical instrument having a keyboard with keys which produces polyphonic musical notes. The device is an organ which covers at least one octave of musical notes. The octaves are aligned in bands of concentric rings located on the top of the instrument. Each band of keys may contain one octave of notes. Notes in a first octave are next to or nearby identical notes in a second octave to make popular chords and songs easy to play. Notes may be played simultaneously which are octaves apart with one hand due to proximity of all the keys. A hand may extend over a centrally located loudspeaker and be used to vary the loudness and produce vibrato effects. A small overlay having information may be easily placed on the top of the keyboard to assist in learning songs by number, color, or other visual aids.

Claims

1. An electronic musical instrument comprising:

a housing having a top, a bottom, a center and a generally cylindrical side and an interior;

a circular keyboard having a plurality of layers wherein the circular keyboard is located at the top of the housing;

wherein one of the plurality of layers of the circular keyboard has keys wherein the circular keyboard displays at least one octave of musical notes wherein the octave of musical notes are aligned in one of a plurality of bands of concentric rings wherein a first note of an octave of a first band is adjacent to an identical first note of another octave of a second band; and

a generally cylindrical support located within the interior of the housing at the center of the housing wherein the generally cylindrical support supports the circular keyboard above the bottom of the housing and wherein the generally cylindrical support contains a loudspeaker wherein the loudspeaker produces an audible sound based on the notes played on the circular keyboard.

2. The electronic musical instrument of claim 1 further comprising:

an integrated circuit electronically connected to the circular keyboard wherein the integrated circuit is located within the interior of the housing wherein the integrated circuit simultaneously generates one or more octaves of musical notes.

3. The electronic musical instrument of claim 2 wherein the notes in one of the plurality of bands of the concentric rings are shifted electronically with respect to the other bands by shifting a clock input of the integrated circuit which creates the notes for that octave.

4. The electronic musical instrument of claim 1 further comprising:

a conductive pad located beneath one of the layers of the circular keyboard wherein the conductive pad is electrically connected to an integrated circuit.

5. The electronic musical instrument of claim 1 further comprising:

a generally circular overlay layer of substantially the same size as the circular keyboard wherein the generally circular overlay is placed over the circular keyboard and wherein the generally circular overlay has a plurality of numbers, colors, or other indicia for assisting a user in learning to play a song.

6. The electronic musical instrument of claim 5 further comprising:

an LED located on the first layer of the circular keyboard wherein the LED has a diameter;

an opening having a diameter located on the generally circular overlay layer wherein the diameter of the opening of the generally circular overlay layer is the same as the diameter of the LED such that the LED may snugly fit through the opening of the generally circular overlay and wherein the generally circular overlay is prevented from moving with respect to the first layer of the circular keyboard when the LED is located in the opening of the generally circular overlay.

7. The electronic musical instrument of claim 1 wherein the electronic musical instrument is water resistant.

8. The electronic musical instrument of claim 1 further comprising:

a generally circular rim extending above the circular keyboard wherein the generally circular rim has a circumference equal to a circumference of the housing and wherein the generally circular rim extends from the generally cylindrical side of the housing;

a generally spherical ball placed over the top of the housing wherein the generally spherical ball rolls over and activates the circular keyboard and produces random notes; and

wherein the generally circular rim prevents the generally spherical ball from falling off the circular keyboard.

9. The electronic musical instrument of claim 1 further comprising:

an additional key which is added to the circular keyboard wherein the additional key allows a user to play common chords by pressing only one key.

10. The electronic musical instrument of claim 9 wherein a chord may be changed electronically by shifting a clock input of an integrated circuit.

11. The electronic musical instrument of claim 1 further comprising:

an electronic loudspeaker located on the generally cylindrical side of the housing.

12. The electronic musical instrument of claim 1 wherein the keys of the circular keyboard are triangular in shape and wherein the keys become broader the closer the keys are to the cylindrical side of the housing.

13. The electronic musical instrument of claim 1 further comprising:

a second loudspeaker wherein the second loudspeaker is located on the generally cylindrical side of the housing; and

a switch located on the housing wherein a user may use the switch to determine if the loudspeaker at the center of the housing is activated, the second loudspeaker of the generally cylindrical side of the housing is activated or both are activated.

14. An electronic musical instrument comprising:

a housing having a top, a bottom, a center and a generally cylindrical side and an interior;

a circular keyboard having a first layer, a second layer and at least a third layer wherein the circular keyboard is located at the top of the housing;

wherein the first layer of the circular keyboard has keys and wherein the first layer of the circular keyboard displays at least one octave of musical notes wherein the octave of musical notes are aligned in one of a plurality of bands of concentric rings; and

a generally cylindrical support located within the interior of the housing at the center of the housing wherein the generally cylindrical support supports the circular keyboard above the bottom of the housing and wherein the generally cylindrical support contains a loudspeaker wherein the loudspeaker produces an audible sound based on the notes played on the circular keyboard.
