INTERNALLY INTEGRATED DIGITALLY AMPLIFIED ELECTRONIC GUITAR

GUITARE ELECTRONIQUE A AMPLIFICATEUR NUMERIQUE INTEGRE INTERNE

English Abstract

The INTERNALLY INTEGRATED DIGITALLY AMPLIFIED ELECTRONIC GUITAR adds new
minuature digial
technology to standard electric guitars by utilizing various integrated
circuits inside the body of the invention to replace the
standard external devices standard electric guitars require in order to
operate. The external devices the standard electric
guitar requires to operate are: (1)-interface cable, (2)-audio amplifier, (3)-
speakers) and (4)-speaker cabinet. With standard
electric guitars a magnetic coil pickup (or pickups) captures the magnetic
flux created by the guitar strings vibrating and
carries that signal through a series of tone controls through an I/O connector
or out-put jack on the external side of the body
of the guitar. An interface cable is then required to be inserted into the
guitar at one end and the other end of the interface
cable is then inserted into the I/O connector or input jack of an external
audio amplifier (powered by AC or DC current)
where the signal is boosted and routed to output speakers (which may require
or not another separated I/O connection )
between the amplifier and the speaker.
With the INTERNALLY INTEGRATED DIGITALLY AMPLIFIED ELECTRONIC GUITAR all
components required
for operation are contained within the guitar. The signal passes from the
vibration of the strings to a Hex Magnetic or piezo
electric MIDI Pickup and is converted from a anlogue signal to digital
information. The digital information is then manipulated
by internal tone controls via a MIDI (music instrument digital interface)
synthesizer and sent to the internal Digital Amplifier
which boosts the signal and creates either a mono or stereo output path which
connects directly to the systems internal set of
Digital Speakers. Due the extreme minuaturization of the IC components the
entire system can operate on DC current
provided by on-board rechargable batteries. The INTERNALLY INTEGRATED
DIGITALLY AMPLIFIED
ELECTRONIC GUITAR offers significant advantages over the standard electric
guitar. It is portable and requires non of
the external devices that a standard electric guitar does in order to operate.
The INTERNALLY INTEGRATED DIGITALLY
AMPLIFIED ELECTRONIC GUITAR can operate anywhere without the need for an
external AC power source. The
INTERNALLY INTEGRATED DIGITALLY AMPLIFIED ELECTRONIC GUITAR DC power cells can
be conveniently
recharged with it's on-board charging system and the Digital Amplifier and
Digital Speaker system draws less electrical
power and delivers superior sound quality over conventional solid state or IC
analogue amplifier/speaker combinations.
With the on-board MP3 player/recorder; the musician can record the output of
the guitar listen to it later and/or accompany
the output of the MP3 player by playing the guitar as the MP3 player
replicates what is stored on it's hard drive.

Claims

CLAIMS:
THE EMBODIMENTS OF THE INVENTION
INTERNALLY INTEGRATED DIGITALLY AMPLIFIED ELECTRONIC GUITAR
IN WHICH AN EXCLUSIVE PROPERTY OR PRIVILEGE IS CLAIMED ARE:
1. The utilization of DC rechargeable nicad batteries to power all aspects of
the
INTERNALLY INTEGRATED DIGITALLY AMPLIFIED ELECTRONIC GUITAR
2. The utilization a HEX Magnetic or Piezo Electric MIDI Pickup with circuitry
that buffers the signals
and filters out the harmonics for pitch analysis. After filtering, the
microprocessor determines the
pitch played by measuring the time of one sinus vibration (half of one cycle)
which is the shortest
part of the note. This alows the pickup to make a positive analysis in only
one cycle under optimum
conditions. As soon as the pitch is confirmed, the microprocessor instantly
sends the information as a
standard MIDI message (note number and velocity) to the onboard midi
synthesizer processor.
3. The utilization of Digital Amplifer and Circuit Board with a controller and
a power device which
provide full digital audio preamplifer functions and power amplification. The
device supports both
coaxial and optical S/PDIF interfaces, digital volume and balance controls and
local power regulation
to operate from a signal supply voltage. The amplifier can be configured in
both mono or stereo
versions. The power device is dual channel H-bridge that can deliver over 35
watts per channel of
audio power. The amplifer design includes; a logic interface, integrated
bridge drivers, high effiency
MOSFET outputs and protection circuitry. Two logic level signals per channel
are used to control
high speed MOSFET swirches to connect the speaker load to the input supply or
ground in a bridge
configuration. The amplifier also includes over-current, thermal, and over-
voltage protection and
under voltage lock-out with automatic recovery. A thermal warning status is
also provided. This
device is also capable of interfacing as with the analogue to digital
converter data as well as with
MP3, CD and DVD players and components.
4. The utilization of Digital Speakers with home theatre sound quality
utilizing linear magnetic
drive technology to deliver hi-fi quality sound which are also capable of
interfacing as with the
with MP3, CD and DVD players and components.
5. The utilization of a singular enclosure, body or chassis to enclose and
integrate all the components
of the INTERNALLY INTEGRATED DIGITALLY AMPLIFIED ELECTRONIC GUITAR
including the tuning keys, the guitar neck, the fret board, the strings, the
bridge and all the electronc components
including the internal MIDI Synthesizer, Digital Amplifier, Digital Speakers,
MP3 Player/Recorder, rechargable
batteries and the AC/DC battery charger constructed from either: wood , metal
alloy, gold, silver, brass, aluminum,
titanium, fiberglass, carbon fibre or composite materials.
6. The utilization of an on-board MP3 player/recorder with a 6GB hard drive,
which gives you real-time,
on-the-fly recording of up to 6000 minutes of top-quality music in MP3 format.
It can record directly
from any audio source, including the digitally amplified signal coming from
the guitar strings via the
stereo, line-in jack. With the on-board MP3 recorder/ player, the musician can
record the output of the guitar
listen to it later and/or accompany the output of the MP3 player by playing
the guitar as the MP3 player
replicates what is stored on it's hard drive. The INTERNALLY INTEGRATED
DIGITALLY
AMPLIFIED ELECTRONIC GUITAR is compatible with a Pentium 233MHz or higher, Win
98 SE/
2000/Me, 32MB RAM (64MB recommended), CD-ROM drive with digital audio
extraction support,
Mac OS 8.6 or higher, iMac/G3/ or higher.
