Description: APPARATUS AND METHOD FOR RECORDING MUSIC FROM A GUITAR HAVING A DIGITAL RECORDER AND PLAYBACK UNIT LOCATED WITHIN THE GUITAR FIELD OF THE INVENTION This invention relates generally to apparatus and methods for recording musical sounds from a musical instrument and, more particularly, to an apparatus and method for recording long lasting, high quality, noise-free musical sounds from a single hand-held, portable guitar. BACKGROUND OF THE PRIOR ART In the past, recordings of music generated by musical instruments were created on various recording mediums such as musical records, cassette type or other forms of magnetic recording mediums. The recordings of such music were usually created for public listening and a great deal of care was taken to create a "master" recording with the highest quality of musical sound that was possible so that many multiple recordings could be generated from the "master" recording for dissemination to the public. While most of these recordings were previously for public listening, the musicians playing various musical instruments were very desirous of achieving recording of musical sounds that they generated so that they could capture the "magic moment" when they created a particular combination of musical sounds that might lead to or become an important musical piece. Thus, musical recordings for public use and listening pleasure is on a macroscopic level relative to creating musical recordings of a single musical instrument for the musician playing the musical instrument which is on a microscopic level. In either situation, whether it was the public listening to the musical recordings or the musician listening to the musical sounds created by the musician from a single musical instrument, it was extremely important to create higher quality, noise-free musical sounds. Conventional tape recordings of these musical sounds were not able to eliminate undesired distortions that were created by noise in the vicinity of the tape recording operation. Very expensive sound recording studios were used to try to eliminate noise that reduced the quality of the musical sounds that were to be recorded. However, as a practical matter, musicians desiring to play their musical instruments could not race over to a sound recording studio every time they were playing their musical instruments to try to record high quality musical sounds from their musical instruments. Furthermore, as is well known, inspiration may come and go in a fleeting few moments, therefore, it is imperative that musicians be able to obtain instant high quality, noise-free recordings of their creative musical renditions. This is especially applicable for musicians playing music on their handheld, portable musical instruments such as guitars or other types of string type instruments. U.S. Patent 3,562,397 utilized a tape recorder in a certain type of console electronic musical instrument to try to record higher quality musical sound. However, this disclosed arrangement was for a large electronic console type musical instrument and was not practical for use with hand-held, portable musical instruments such as guitar or other types of string type instruments. U.S. Patent 3,746,772 is similar to U.S. Patent 3,562,397 and directed to a keyboard type electronic musical instrument with a built-in tape recorder to try to record high quality musical sound. However, the problem with both U.S. Patent 3,746,772 and 3,562,397 is that the tape recorder records the musical sounds on a magnetic tape medium which is not very good for maintaining long lasting sound quality. Furthermore, these two prior art console type music recording systems use analog recording techniques rather than the much better, higher quality, longer lasting attributes of a digital recording system. Additionally, the tape recorders of these two prior U.S. Patents do not readily permit implementation in hand held, portable musical instruments such as guitars. Consequently, a need existed for an apparatus and method for instantaneously recording long lasting, high quality, noise-free musical sounds from a hand-held, portable guitar in a digital rather than an analog format. SUMMARY OF THE INVENTION Accordingly, it is an object of this invention to provide an improved apparatus and method for recording long lasting, high quality, noise-free musical sounds from a hand-held, portable musical instrument. It is a further object of this invention to provide an improved apparatus and method for recording long lasting, high quality, noise-free musical sounds in a digital format from a handheld, portable musical instrument such as for electric, acoustic and classical guitars. It is a still further object of this invention to provide an improved apparatus and method for recording long lasting, high quality, noise-free musical sounds in a digital format from a handheld, portable musical instrument such as for electric, acoustic and classical guitars wherein recording in the digital format is achieved by incorporating a digital recording unit within a portion of the housing of the electric, acoustic and/or classical guitar.

Referring to Figure 3 which illustrates the guitar 10 of Figures 1 and 2, reference number 41 designates a new feature of the guitar 10 which is, in effect, a port for permitting, for example, a microphone input jack from a microphone (not shown) to be inserted into the port 41 to permit voices or other sounds to be inserted into the inner portion of the guitar 10 for merging with musical sounds generated by a musician or user playing the guitar 10. These merged sounds can be digitally recorded by the mini-disc unit D. Reference number 42 is a D.S.P. (Digital Sound Processing) selector switch to permit selection of any of the following (Reverb-Echo-Flange-Chorus-Distortion) which can be used in digital recording for the mini-disc unit D. Referring to Figure 4, this Figure corresponds to Figure 1 and provides a further clarification thereof. Reference number 51 designates a door for the mini-disc unit D which serves to permit entry therein and removal therefrom of a mini-disc 52. Thus, individual mini-discs 34 of Figure 2 can be inserted into and, after recording thereon, removed from the mini-disc unit D using the door 51 thereof. Referring to Figure 5, the flow type diagram of this Figure illustrates the interconnection of the various elements or components of the guitar apparatus 10 that is depicted in Figures 1 and 2. The electric guitar 10 is electrically coupled to the mini-disc unit D through the switch 13 or switch unit 13 which, as was described above with reference to Figure 1, serves to switch analog output 60 of the guitar 10 to provide an analog input 62 to the mini-disc unit D. The switch or switch unit 13 can selectively switch the analog output 60 from the guitar 10 to provide an input 64 to the guitar output headphones or headphones 32 (see also Figure 2), if desired, so that the user or musician can instantaneously listen to the analog musical input 60 from the guitar 10. The mini-disc unit D can provide, if desired, an output 66 of the music contained therein to the guitar output headphones 32 after proper selection for this mode of operation by the switch or switch unit 13 which receives the output 66 from the mini-disc unit or recorder D and sends it on to the guitar output headphone or headphones 32 by means of the input 64 thereto. The (battery or transformer) power pack 35 that is used to charge the mini-disc unit or recorder D provides the D.C. voltage source thereto (by means of conduit 68) as described with reference to Figure 2. As was also described with reference to Figure 2, the digital output 33 from the mini-disc unit D is provided by means of output conduit 69. With reference to both Figures 3 and 5, a microphone or, if desired, another musical instrument 41 can provide an analog input to the guitar 10 by means of its analog output line 70 to the bidirectional line 60 going to the guitar 10. This permits blending of the sounds from the microphone or second instrument 41 into the guitar 10 which provides a total analog output 60 to the switch 13. Referring to Figure 6, this flow diagram type Figure is similar to the flow diagram of Figure 5. Therefore, the description of Figure 5 (as well as the description of associated Figures 1,2 and 3) are incorporated into the description of this Figure 6. Accordingly, the same reference numbers are used with reference to Figure 5 are used in this Figure 6. In the embodiment of Figure 6, digital effects 72 are provided as an input 74 to the switch or switch unit 13 after receiving the analog output 60 from the guitar 10 by means of conduit 70A which may also contain voice from a microphone or music from another (second) musical instrument if such is imputed to the guitar 10 from the analog output line 70 connected to the microphone or second instrument 41. Thus, the combined input 74 to the switch or switch unit 13 from the guitar 10, the microphone or second instrument 41 and digital effects 72 permits the switch 13 to provide, as described above, the input 64 to the headphone or headphones 32 and/or to the input 62 to the mini-disc unit or recorder D. Referring to Figure 7 in combination with the other Figures of this patent application including specifically Figures 1 and 2, electrical connections are shown beneath the outer surface of the guitar 10 as depicted in Figures 1 and 2. As discussed above, the guitar 10 shown in Figures 1 and 2 is a 3 pickup guitar having a neck pickup A (located near the neck of the guitar 10 in Figure 1), a middle pickup B located below the neck pickup A, and a bridge pickup C located below the middle pickup B. Three pickup wires are provided to each of the three (A, B, C) pickups of the guitar 10. The three pickups A, B, and C function similar to the three pickups of an electric guitar wherein the use of permanent magnets in association with an electrical coil (for the electric guitars) serves to create different changes in the magnetic flux because of the associated moving conductive (metal) wires of the electric guitar. For classical guitars where non-metal wires are used, piezoelectric quartz crystal devices are used to sense the different vibrations of the non-magnetic wires of the classical guitar and to generate electrical signals corresponding to these vibrating non-metal wires. A positive electrical signal is generated by the vibrating wires of the guitar 10 on the line R for the neck pickup A, the middle pickup B and/or the bridge pickup C. A negative signal is generated by the vibrating wires of the guitar 10 on the line Bl of the neck pickup A, the middle pickup B and/or the bridge pickup C. In the use of a shield type wire covering, a negative signal is produced on the line S for the neck pickup A, the middle pickup B and/or on the bridge pickup C. The volume control 12 (see Figure l)is shown in Figure 7 as having an electrical contact with both the negative Bl and shield S lines from the neck pickup A, the middle pickup B and the Bridge pickup C. The volume control 12 as shown in Figure 7 has two other terminals, one (the other end one) is electrically connected to the S5 Switch 11 shown in Figure 7. The volume control 14 has one (outside) terminal thereof connected to wires Bl and S of each of the pickups A, B, and C through a capacitator Cl. The center terminal of the tone control 14 is connected to a center terminal of the S5 Switch 11. The center terminal of the volume control 12 is connected to the switch 13 which is shown as a biplole switch connectable to either a jack 80 (that is located beneath the mini- disc unit D of Figure 1 and connected to an input port (not shown) beneath the mini-disc unit D) or to a jack 82 (that is also located beneath the mini-disc unit D of Figure 1) and connected to an output port (not shown) beneath the mini-disc unit D) . A ground (or negative) connection is made by wire 84 from the guitar output 16 (that is shown in Figure 7 as a guitar and mini-disc jack, however, a port for the external electrical connection is located within the threaded portion of the jack - with the threaded portion used to secure this jack to the envelope of the guitar 10) to each of the jacks 80 and 82 by means of wires 84A and 84B electrically connected to the wire 84. The positive terminal of the guitar and mini-disc output jack is connected to the other wires 86A and 86B respectively connected to the input jack 82 by means of wire 86 (which is directly connected to the jack 82) . The positive terminal of the guitar and mini-disc output jack is connected (by means of the selection switch 13 in the position shown in Figure 7 to the (middle terminal) of the volume control 12. The positive signal generated by the pickups A, B, or C is conducted using the respective R wires of each of these pickups to (three) different terminals of S5 Switch 11. While the invention has been particularly shown and described with reference to the preferred embodiments thereof, it will be understood by those skilled in the art that the foregoing and other changes in form and details may be made therein without departing from the spirit and scope of the invention. For example, implementation of the mini-disc unit D into the housing or envelope of an acoustic or classical guitar can be performed in accordance with the teachings of this invention.
