GUITAR, RADIO, MICROPHONE COMBINATION WITH SELF-CONTAINED ENERGY SOURCE AND AMPLIFIER BACKGROUND OF THE INVENTION 1. Field of the Invention This invention is in the field of musical instruments.
2. Description of the Prior Art In the U. S. Pat. No. 3,550,495 issued to Shotmeyer, there is disclosed a musical instrument which combines a guitar and a tape reproducer whereby a mixed sound can be reproduced. Likewise, in the U. S. Pat. No. 3,296,916 issued toPalmer, there isdisclosed a musical instrument which includes a guitar in combination with a microphone. Disclosed herein is a musical instrument which combines a guitar with a radio and microphone.
Electrical guitars require various electrical cords which extend from the guitar to the source of electrical energy such as a standard outlet found on a wall. In addition, the guitar must be connected by electrical cords to the amplifying system. As a result, the movement of the musician is restricted and frequently, the electrical cords become entangled in the musicians feet. As a result, l have designed an electrical guitar which is selfcontained having a battery source of electrical energy mounted within the guitar and having the amplifier also built into the guitar. Thus, various electrical cords are not required thereby allowing the musician to move freely as the instrument is played. Simultaneously, I have mounted the microphone onto the guitar thereby not requiring the musician to stand in a relatively fixed position near the microphone found on the stage. In order to obtain a unique sound, I have mounted a radio within the guitar. Thus, the musician may sing and be accompanied by either music from the radio, music from the guitar or a combined music from the radio and guitar. A unique feature of my invention is utilization of the amplifier of the radio to amplify both the sounds from the microphone and guitar strings as well as the radio.
Other patents of interest are the U. S. Pat. No. 3,357,291 which is issued to Carmichael which discloses a guitar having a self-contained amplifier and the U. S. Pat. No. 1,739,680 issued to La Joie which is a combination radio and phonograph.
SUMMARY OF THE INVENTION One embodiment of the present invention is a musical instrument comprising a guitar having a hollow main body forming a sound box with a long neck attached thereto and strings with opposite ends attached to the neck and the main body, a battery holder mounted within the main body for receiving at least one battery, the holder having electrical output terminals contactable with the battery for providing electrical energy, a radio receiving set mounted within the main body and connected to the terminals for the operation of the set, the radio receiving set including antenna means, an audio speaker and a first amplifier, a microphone mounted to the guitar and being electrically connected to the terminals, the microphone having an output line connected to the amplifier, first means mounted to the main body beneath the strings being electrically connected to the terminals and the amplifier and being operable to produce audio electrical signals in proportion to sounds generated by the strings, and switch means mounted to the guitar and connected between the amplifier and the antenna means, between the amplifier and the microphone and between the amplifier and the first means, the switch means being operable to control electrical signal flow from the antenna means, the microphone and the first means to the amplifier.
It is an object of the present invention to provide a new and improved musical instrument.
It is a further object of the present invention to provide a musical instrument which combines the features of the guitar, radio and microphone Yet another object of the present invention is to provide a guitar, radio, microphone combination which utilizes a single amplifier for amplifying the sounds from the guitar, radio and microphone.
In addition, it is an object of the present invention to provide a guitar, radio, microphone combination which has a self-contained source of electrical energy and a self-contained amplifier thereby not requiring any external electrical cords.

DESCRIPTION OF THE PREFERRED EMBODIMENTS For the purposes of promoting an understanding of the principles-of the invention, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended, such alterations and further modifications in the illustrated device, and such further applications of the principles of the invention as illustrated therein being contemplated as would normally occur to one skilled in the art to which the invention relates.
Referring now more particularly to FIG. 1, there is shown a musical instrument 10 which is a guitar having a hollow main body 11 forming a sound box with a long neck 12 attached to main body 11. Six strings 13 are strung on the guitar having their opposite ends attached to the neck and the main body in the conventional manner. The main body 11 has a top panel 14 and a bottom panel 15 spaced apart and connected to an outer wall 16. Panel 14 is provided with hole 17 which extends beneath strings 13. An audio speaker 18 is mounted to the inside surface of panel 14 and is positioned adjacent hole 17. Speaker 18 is connected to a radio mounted within main body 11, to microphone 19 mounted to side wall 16 and to device 20 which produces electrical signals in response to the sounds generated by strings 13.
. Th musical instrument utilizes the amplifier of the radio mounted within the main body to amplify the sounds from the radio receiving set, the sounds picked up by microphone 19 as wellas the sounds picked up by device 20. The radio receiving set may be of the AM type with the schematic for the AM radio receiving set being shown in FIG. 4 or may be of the FM type with the electrical schematic for the FM type radio receiving set being shown in FIG. 5. Referring now to FIG. 4, there is shown an antenna 21 connected to tuner 22 which in turn is connected to RF amplifier 23. Amplifier 23 is provided with a local oscillator 24 with the output of the amplifier being connected to'mixer 25. This circuitry is well known with the RF amplifier merely amplifying the station to which tuner 22 is positioned with the amplified signal having an audio modulation passed onto mixer 25. Typically, local oscillator 24 produces a 455 KC signal which is then mixed with the incoming signal and fed into the IF amplifier 26. Amplifier 26 provides a signal to detector 27 which removes the 455 KC RF component from the audio modulation component and normally passes this component into the first audioamplifier 28. Instead of the normal relationship between detector 27 and amplifier 28, the output of detector 27 is fed through a three deck/- three position switch 27' which is also connected to microphone 19 and device 20. The output of switch 27' is then connected to amplifier 28 which in turn is connected to amplifier 29. Speaker 18 is connected to the output of amplifier 29. 7
I the power supply is connected to the input power line of microphone l9 and the input power line of device 20. Switch 31is also the volume switch for the radio receiving set and may be turned so as to control the flow of electrical energy to the radio receiving set. Switches 32 and 33 are volume switches respectively for microphone l9 and device and are connected between the output lines respectively of microphone 19 and device 20 and contacts 6 and 30f switch 29. Wipers A, B and C are mechanically linked. When the wipers are in the positions adjacent contacts 1, 4 and 7, only microphone 19 will be connected to amplifier 28. Likewise, when wipers A, B and C are positioned adjacent contacts 2, 5 and 8, both microphone 19 and device 20 will be connected to amplifier 28 whereas when the wipers are positioned adjacent contacts 3, 6 and 9, the microphone 19, device 20 and detector 27 will be connected to amplifier 28 thereby allowing the sounds received by the radio receiving set, the sounds received by the microphone and the sounds received by device 20 to be amplified simultaneously via amplifier 28 and then to emit from speaker 18.
The circuitry shown in FIG. 5 is identical with respect to the circuitry shown in FIG. 4 with the exception that the radio receiving set is of the FM type and therefore,
incorporates a limiter 34 and discriminator 35. The antenna, tuner and RF amplifier are connected via converter 36 to the IF amplifier 37 which in turn is connected to limiter 34. Limiter 34 is a specialized RF amplifier and eliminates the noise effects from the signal. Discriminator 35 changes the rate of frequency variation into voltage variations. The output of discriminator 35 is connected to switch 27' in a manner identical to the connection of the output of detector 27. Likewise, the output of switch 27 is connected to amplifier 29 in an identical manner as described for the connection between switch 27 and amplifier 28. In addition, the same connections are made between microphone 19 and device 20.
Selector switch 27' is therefore connected between the amplifier and antenna means 21, between the amplifier and microphone l9 and between the amplifier and device 20 with the selector switch being operable to control the electrical signal flow from the antenna, microphone and device 20 to amplifier 29. The selector switch is mounted to top panel 14. Likewise, the onoff/volume switch 31 is mounted to panel 14 along with microphone volume switch 32 and guitar volume switch 33. l
A door 38 is hingedly mounted to panel 15 (FIG. 3) in order to allow access to the battery pack 39. Pack 39 has a plurality of batteries removably mounted therein and connected to the output terminals 40 and 41. Onoff/volume switch 31 is connected between terminals 40 and 41 and the radio receiving set which has its components mounted to terminal board 42 secured to the inside surface of panel 14. Likewise, the onoff/volume switch is connected between terminals 40 and 41 and the microphone and between terminals 40 and 41 and device 20. Terminals 40 and 41 are contactable with the batteries secured within passage 39 for providing the electrical energy for the various components.
Many variations are contemplated and included in the present invention. For example, additional speakers, such as four speakers, may be mounted to the main body of the guitar in lieu of the single speaker shown in the drawing. It will be obvious from the above description that the present invention provides a new and improved musical instrument. It will be further obvious from the above description that the present invention provides a guitar radio microphone combination which has a self-contained power supply and amplifier thereby eliminating the necessity for external electrical cords.
A variety of devices may be utilized to pick up the sounds generated by the guitar strings. A popular version of device 20 incorporates a magnetic coil with sensors positioned immediately below the guitar strings. The magnetic coil produces electrical signals in proportion to the sounds generated by the strings.
While the invention has been illustrated and described in detail in the drawings and foregoing description, the same-is to be considered as illustrative and not restrictive in character, it being understood that only the preferred embodiments have been shown and described and that all changes and modifications that come within the spirit of the invention are desired to be protected.
