Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in electric guitars, and more particularly to improvements in electric guitars, and in particular to improvements in electric guitars.
r: A guitar that does not amplify the sound using an electrical device) or an amplified acoustic guitar (amplified acoustic guitar)
This invention relates to an electric guitar that can also be used as an electric guitar.

Traditionally known electric guitars, especially electric guitars that are played at relatively high volumes, have a solid (non-hollow), highly rigid body with an electromagnetic pickup device (hereinafter referred to as a pick) for detecting string vibrations. A pickup device (referred to as an amplifier device) is attached to the pickup device so that the signal output from the pickup device can be amplified as the output of the guitar. Although such electric guitars are well known and widely used for playing relatively popular music in modern music, when played without a pink amplifier or amplification device, The sound quality and musical characteristics required of a normal acoustic guitar used to play relatively traditional or classical music cannot be obtained at sufficient volume to be audible. is not obtained. In order to amplify the music produced by an acoustic guitar crab, which has a hollow body made of thin plate material, a transducer is attached to the top face or other parts of the body, and the vibrations of the body are detected. Attempts have also been made to amplify the electrical signals obtained therefrom. However, this solution is not completely satisfactory, especially when the signal is amplified to a large extent, because it causes problems such as feedback and causes distortion of the output.

It is an object of the present invention to combine the characteristics of both the amplified acoustic guitar and the conventional electric guitar, and furthermore, it is an object of the present invention to provide a guitar that can be used when playing in a narrow space or when practicing playing. To provide a guitar which can be used as an acoustic guitar which allows a player to perform live with high sound quality without using any electric amplification device when required by a player.

An electric guitar according to the invention includes a hollow body with a bridge on the top face, a neck rigidly attached to the body and having means for tensioning strings fixed to the bridge; The main body includes a highly rigid bottom and side portions forming a hollow internal bottom and sides, and a relatively low rigid top table that closes the internal hollow and to which the bridge is fixed.

A first electric pickup device is rigidly attached to the bottom of the body within the interior hollow, and the electric pickup device is inserted through an opening formed through the top table to connect the guitar strings. They are protruded to a position where they can work together.

Preferably, one pickup device, a lead pickup device, is provided near the bridge, and a second pickup device, a rhythm pickup device, is provided near the bridge.
A pickup) is provided between the first pickup device and the neck. Furthermore, preferably, the second pink-up device includes a
It is also possible to provide it so as to extend from a portion firmly fixed to the metal portion of the main body. With this configuration, the acoustic performance mode of the guitar (acoust
The vibrating part of the top table that vibrates during the ic mode) is a first pink amplifier device, that is, a lead, which has an opening formed therein and is firmly fixed through the opening in the part of the top table that closes the internal hollow. The pink amplifier device is the prominent part.

Furthermore, by providing a transducer on the lower surface of the relatively low-rigidity top table facing the inner hollow inside the main body, it is possible to provide the guitar with an output similar to that of an amplified acoustic guitar. be. In addition to conventional switches for adjusting the volume and tone of the lead pickup device and rhythm pickup device, the guitar also includes a selection switch to select between the guitar's performance modes, namely electric performance mode and amplified acoustic performance mode. It is also possible to provide it on the top face of.

In order to enhance the vibration characteristics of the top table located above the internal hollow and improve the acoustic characteristics in the acoustic performance mode of the guitar, the top table is made of a relatively resilient (flexible) material such as Ezo pine. It is desirable to construct it from high quality materials. Furthermore, on the bottom (back) of the top table,
It is desirable to provide appropriate reinforcing ribs. With such a configuration, the bridge is fixed to the reinforcing rib via the top table.
The bridge can be relatively large (having a large mass) and rigid. As a result, the ability to support the strings of the guitar in the electric performance mode is enhanced, and the top table, which is a vibrating member, is suitably vibrated in the acoustic performance mode, resulting in excellent sound quality.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below based on drawings showing one embodiment thereof.

In Figure 1, the neck 11 extends from the guitar body.
is provided with a normal head 10.

The bridge 16 is placed on the top table 23 of the guitar body.
is fixed, and a string extending over the fret board on the neck 11 is stretched between the bridge 16 and the head 10. A rhythm pickup device 12 and a lead pink up device 13 from the inside of the guitar body to the outside.
are provided so as to protrude, and these pickup devices detect the vibrations of the strings when the guitar is in the electric performance mode. Furthermore, various operation switches are arranged on the top table 23 of the guitar.

That is, the pink-up selection switch 17 is used when the guitar is in the electric performance mode, and is in a position where only the lead pickup device 13 is selected, a position where only the lead pickup device 13 is selected, a position where the lead pickup device 13 and the rhythm pickup device 12 are selected. It has three operating positions: a position for selecting both of the above, and a position for selecting only the rhythm pick arrangement device 12. The second selection switch 14 has two operating positions, one for selecting the electric performance mode and the other for selecting the amplified acoustic performance mode.

Knobs 19 and 21 are also volume control knobs used when the guitar is placed in amplified acoustic performance mode and electric performance mode, respectively. Furthermore, the knob 18 is a tone control knob for adjusting the tone quality of the rhythm pickup device 12. The tone control knob 18 is provided with a push-pull type switch for controlling a conventional variable coil tap device provided for the rhythm pink amplifier.

Further, the knob 20 is a torque control switch for the lead pick amplifier device 13, and has the same function as the knob 18.

Note that although a specific operation switch configuration has been described above, it is possible to change it as necessary. For example, it is possible to provide a common volume control switch that can be used in both the amplified acoustic performance mode and the electric performance mode.

As can be seen in FIG. 2, the body of the guitar is provided with a sufficiently rigid solid bottom and side walls 32 defining an interior hollow 24 thereof.

These parts of the guitar body are made sufficiently solid and have increased rigidity so that they can perform the same function as the solid body of a conventional electric guitar. A mounting block 25 is provided inside the internal hollow 24 and is firmly fixed to the bottom of the guitar. On the other hand, a recess 33 for attaching the rhythm pink-up device W12 is formed in the main body of the guitar. Internal hollow 24
Furthermore, an acoustic preamplifier 31 is attached to a solid side wall 32 of the guitar body.

FIG. 3 shows the internal structure of the guitar body. A lead pickup device 13 is attached to the block 25 inside the internal hollow 24, and this pink-up device 13 passes through an opening 15 formed in the top table 23 and protrudes from the top face of the top table 23. There is. The rhythmic amplifier device 12 is installed in a recess 33 formed in the guitar body, passes through an opening 28 formed in the top table 23, and projects in front of the top table. As is clear from the above explanation, the rhythm pink-up device 12 is connected to the top table 23.
It is desirable that the oscillator protrudes from a non-vibrating portion that is firmly fixed to the guitar body.

Top table 2 that closes the internal hollow 24 of the guitar body
In order to provide excellent sound quality to the vibrating part 3, it is preferable that the top table be made of Ezo pine. Also,
In order to obtain excellent acoustic properties, it is desirable that the bridge 16 be made of solid metal, fairly large, and fixed in place with bolts. That is, in this embodiment, the mounting bolt 29 passing through the top table 23 is attached to the bottom (back side) of the top table 23 facing the internal hollow 24.
The bridge 16 is fixed in a predetermined position by screwing into the main portion 27 of the reinforcing rib shown in FIG. 4 fixed to the surface. This reinforcing rib is provided with a plurality of arms 26 extending radially from the raw portion 27 toward the side wall 32 of the guitar body. Furthermore, a transducer 3o is fixed to the lower surface of the top table 23, which is operated in the amplified sound performance mode of the guitar.

As described above, the constructed electric guitar has sufficient rigidity and has the same functions as a conventional electric guitar, while the pink amplifier device is turned off and the transducer 3
It has been found that by turning on o, it is possible to easily switch from the electric performance mode to the amplified acoustic performance mode, resulting in a performance that is at least comparable to that obtained with an amplified acoustic guitar. Furthermore, the internal hollow 24 formed inside the guitar body is used as a sound box, and the top table 23, which is made of flexible wood and appropriately reinforced with ribs, located above the top table 24 is used as a vibration member. With this simple configuration, it is possible to obtain a fairly large and appropriate volume output in the normal amplified sound-performance mode without using any electrical amplification equipment.

In order to achieve normal high-quality performance, it is conceivable that the body of the guitar is made primarily of wood, but other materials such as reinforced plastic may also be used to form the body of the guitar, as shown in the drawings. It is also possible to make suitable structural changes that differ from the structure described above.

In addition, in the above embodiment, the fretboard is located at the neck 1.
However, in place of this fretboard, it is also possible to use the pitch board described in British Patent Specification No. 1.511840.
