English Abstract



An electronic synthesized steelpan drum resembling a conventional steelpan
drum and
featuring the same shallow cylindrical shape with a sunken concave playing
surface. The
steelpan drum includes a central processor chip and associated memory chips
for providing a
variety of synthesized steelpan and a full range of musical, orchestral, and
symphonic
instrumental sounds, including tenor, double-seconds, guitar, cello,
quadraphonic, tenor-bass,
and bass steel drums. The concave playing surface is comprised of a series of
rubber striking pad
areas, which can be arranged in a conventional or other unique pattern typical
of a tenor pan.

The striking pad areas will be played with a pair of pansticks. Attached under
each pad is a
pressure sensor, which will detect the amount of force applied when a pannist
strikes a pad and
provide a signal to the central processor for controlling the synthesized
sound. The steelpan has
various control functions including speakers, volume control, function
selection buttons, and a
control display panel.


Note: Claims are shown in the official language in which they were submitted.



CLAIMS

WHAT IS CLAIMED IS:

1. An electronic steelpan drum, comprising:

an oval can-like outer housing with extended control function surface along
one
side, said outer housing having a top circular sunken concave playing surface,

the height of said outer housing being of varying lengths for aesthetic
purposes;
a plurality of striking pads arranged on said concave playing surface, the
area of
said striking pads generally associated with the frequency range of the
generated musical notes;
pressure sensors attached to the bottom side of each said striking pad for
determining the force applied to said striking pad by a pannist;

a central processing chip mounted on a circuit board enclosed within said
outer
housing for electronically controlling the functions of said steelpan drum;
one or more memory chips mounted on said circuit board and coupled to said
central processing chip for storing a variety of synthesized steelpan sounds
and a full range of musical, orchestral, and symphonic sounds to be
reproduced by said steelpan drum;
a plurality of function selection buttons mounted on said control function
surface
along one side of said outer housing for selecting one of said variety of
synthesized steelpan sounds;
audio drivers mounted on said circuit board, the input of said audio drivers
coupled to an audio output of said central processing chip;

volume control equalizing circuitry coupled to the output of said audio
drivers;
one or more speakers mounted on said outer housing, said speakers driven from
said audio drivers;

a display mounted on said outer housing for use in plug-and-play setup and
controlling the basic elements of said steelpan drum; and

a power supply for providing power to said circuit board of said steelpan
drum,

2. The steelpan drum of claim 1, said plurality of striking pads being further

comprised of:
an outer ring of larger striking pads generally associated with lower
frequency
sounds;
a central ring of medium sized striking pads generally associated with mid-
range
frequency sounds; and

a central patch of at least four small striking pads generally associate with
higher
frequency sounds, which will be played with a pair of pansticks.

3. The steelpan drum of claim 1, wherein said outer housing has a convex
bottom
surface.
4. The steelpan drum of claim 1, wherein a free-standing pan stand is used to
hold
said steelpan drum, said free-standing stand having a slot means for receiving

said steelpan drum.
5. The steelpan drum of claim 4, said outer housing further comprising an
attaching
means for hanging said steelpan drum on said free-standing pan stand.

6. The steelpan drum of claim 1, wherein said synthesized steelpan sounds are
configurable from the group consisting of: tenor, double-seconds, guitar,
cello,
quadraphonic, tenor-base, and base.
7. The steelpan drum of claim 1, wherein said basic elements of said steelpan
drum
are selected from the group consisting of: sound type, configuration of
striking
pads, tone, rhythm, melody, harmony, tone color, and equalized volume.

8. The steelpan drum of claim 1, wherein said outer housing is constructed
with
materials from the group consisting of: molded plastic, lightweight metal, and

wood.
9. The steelpan drum of claim 1, wherein said striking pads are made of hard
rubber-
type material.
10. The steelpan drum of claim 2, wherein said pansticks are made of hard
rubber-
type material.

-10-




11. The steelpan drum of claim 1, wherein a musical instrument digital
interface
(MIDI) is provided for interfacing said steelpan drum with other musical
instruments.

12. The steelpan drum of claim 1, wherein said steelpan drum has an audio
output
jack mounted on said outer housing for coupling to an external audio
amplifier.

13. The steelpan drum of claim 1, wherein a CD player/burner port is included
on said
housing and coupled to said central processing chip for mixing other musical,
orchestral, and symphonic instrumental samples with the steelpan drum sound
and for recording the output from said steelpan drum.
14. The steelpan drum of claim 1, wherein a series of equalizing volume
control
buttons are mounted on said outer housing for quick equalization of the sound
from said steelpan drum by a musician.
15. The steelpan drum of claim 1, wherein said synthesized steelpan sounds are
from
the group consisting of: tenor (soprano), double tenor, double seconds, double

guitar, triple guitar, four-pan (cello), quadraphonic, tenor bass, six bass,
