An output transducer connected to a battery powered radio transmitter is contained within the guitar. A remote radio receiver and amplifier converts the radio signal to an audio output through an attached loudspeaker.
BRIEF DESCRIPTION OF THE DRAWING The objects and features of the invention may be understood with reference to the following detailed description of an illustrative embodiment of the invention, taken together with the accompanying drawings in which:
FIG. 1 illustrates a perspective view of the invention;
and
FIG. 2 illustrates a schematic diagram of the invention.
DESCRIPTION OF THE PREFERRED EMBODIMENT tenna 17. The antenna 13 is mounted on the guitar 11 to the face 31 of the guitar 11 and oriented to extend in a plane parallel to the plane of guitar face 31 away from and perpendicular to the axes of the guitar strings 32. This arrangement reduces distortion caused by the strings intercepting and reflecting the electrical waves transmitted by the antenna.
The amplifier radio receiver 16 is linked to a conventional audio amplifier 15 which powers the attached loudspeaker 22 to broadcast the amplified guitar sounds. The amplifier unit 15 is fitted with conventional volume, tone switching and other controls, 26A, 26B, 26C, 26D and 26E respectively and may be powered by internal batteries or by the household electrical service.
Since obvious changes may be made in the specific embodiment of the invention described herein, such modifications being within the spirit and scope of the invention claimed, it is indicated that all matter contained herein is intended as illustrative and not as limiting in scope.
Having thus described the invention, what I claim as new and desire to secure by Letters Patent of the United States is:
1. An electrical guitar equipped with a radio transmitter system which transmits the sounds of the guitar to a remote radio and amplifier unit comprising a guitar fitted with a transducer connected to an amplifier of a radio transmitter located within the guitar, with the output of the radio transmitter led to an antenna mounted to the face of the guitar and oriented to extend parallel to said guitar face in a direction .away from and generally perpendicular to the strings of the guitar.

Claims (1)

1. An electrical guitar equipped with a radio transmitter system which transmits the sounds of the guitar to a remote radio and amplifier unit comprising A GUITAR FITTED WITH A TRANSDUCER CONNECTED TO AN AMPLIFIER OF A RADIO TRANSMITTER LOCATED WITHIN THE GUITAR, WITH THE OUTPUT OF THE RADIO TRANSMITTER LED TO AN ANTENNA MOUNTED TO THE FACE OF THE GUITAR AND ORIENTED TO EXTEND PARALLEL TO SAID GUITAR FACE IN A DIRECTION AWAY FROM AND GENERALLY PERPENDICULAR TO THE STRINGS OF THE GUITAR.
