Description

The present invention relates to a holding device for suspending an acoustic guitar during performance.

The endpin attached to the acoustic guitar is a holding device for hanging and playing the guitar, but for an electric acoustic guitar with a built-in microphone system, the electric signal from the microphone is sent outside the guitar instead of the endpin. It is equipped with an endpin jack equipped with a standard size audio terminal, which corresponds to the description in Patent Document 1.
Hereinafter, the electric acoustic guitar will be referred to as an electric acoustic guitar.

If you want to convert an acoustic guitar that does not have a microphone system into an electric-acoustic guitar, you can choose to use a small-diameter condenser microphone in addition to adopting a dedicated microphone system for electric-acoustic guitar. While many microphones dedicated to acoustic-electric guitars have been developed, small-diameter condenser microphones for audio, which are used for voice conversation, are lightweight and compact, so they can be installed anywhere and are also used for musical instruments. Many inexpensive products have a mini terminal for output, and if you crawl the cable to the body of the guitar and tape it, you do not necessarily need an endpin jack, but I think you need a simple and safe way to attach the cable. Is done.

When the microphone cable 7 is taped to the front plate 12 or the side plate 13 of the guitar, the adhesive of the tape may adversely affect the painted surface of the guitar. In addition, there is a possibility that the tape may come off due to the movement of the performer and the cable may come off, so it is useful to use the endpin jack. However, the end pin hole 16 of the guitar equipped with the conventional end pin 17 has a hole with a diameter of about 8 mm at the insertion port 14, but the outer diameter of the end pin jack is 12 mm, and the end is from the insertion port 14. The hole diameter must be expanded to the size of the endpin jack until it penetrates the block 15, and for acoustic guitar owners who are considering making an electric-acoustic guitar, the cost burden and construction concerns and appearance changes will occur. There is a feeling of resistance. There is also an endpin jack on the market that can be mounted on a guitar without processing by embedding a mini terminal in the conventional end pin 17, but there are concerns about the durability and rigidity of the mini terminal due to the load caused by hanging.

As a remedy for this, a complicated mechanism such as adding an audio jack function to the end pin 17 is not used, but a simple mechanism that can be fixed from the end pin hole 16 included in the end block 15 to the inside of the body of the guitar through the microphone cable 7. We devised a split endpin that is easy to mold.

Hollow processing is possible to make a hole in the axial direction of the endpin 17 through a hole of the same size as the diameter of the microphone cable 7, but the microphone body 6 and the mini terminal (plug) 8 or the mini terminal (plug) 8 or Since the mini terminal (jack) 9 is connected as a set and the set of microphones cannot be passed through the hollowed end pin, the end pin 17 is divided into two in the axial direction, and the axis at the center of both division surfaces. If the grooves are provided at symmetrical positions in the direction and recombined, it is possible to have the same function as the hollowed endpin, and the microphone cable 7 is sandwiched between the divided endpins and integrated into the endpin. Can be fixed in the hole 16.

In the present invention, the endpin jack required for making an acoustic guitar without a microphone system into an electric-acoustic guitar is unnecessary, there is no processing on the body 10 that changes the appearance of the guitar, and only the cable is routed. If you don't need a microphone system, you can return to the conventional endpin 17. In addition, there are only two parts that can be molded with synthetic resin, metal, or wood, which has the advantage of being inexpensive to manufacture.

It is a figure explaining the implementation method to the guitar of the split endpin. It is a figure explaining each part of a split end pin and a set of microphones. It is a figure explaining the implementation method of combining a split end pin and a microphone cable. It is a three-view view of a split end pin. It is sectional drawing of the end pin which showed the conventional example. It is the schematic perspective view of the guitar which showed the conventional example of the end pin.

1 and 2 show examples of the present invention. In FIG. 1, the microphone cable 7 is sandwiched between the split end pin male and the split end pin female, and is integrally inserted into the end pin hole 16 from the insertion port 14 and fixed in the end block 15.

FIG. 2 shows an embodiment in which the split end pin and the microphone cable 7 are combined. If the microphone cable 7 is placed in the cable through groove 5 and the recessed portion 3 of the split end pin female 1 and the protrusion 4 of the split end pin male 2 are aligned and united, the microphone cable 7 and the split end pin female 1 and the split end pin male 2 are combined. Is united, and it looks like a set of microphones pierces the endpin 17.

The endpin 17 attached to the non-acoustic acoustic guitar shown in FIG. 5 is mainly made of synthetic resin or wood, and if the endpin 17 implemented in FIG. 6 is pulled out, it is often the case. A hollow endpin hole 16 appears. FIG. 1 shows a mode in which a microphone cable 7 is sandwiched by a split end pin instead of the end pin 17, and is inserted into an end pin hole 16 together with a set of microphones.

The present invention can be used for musical instruments having a cavity inside.

Claims (2)

The endpin used as a hanging device for a box-shaped stringed instrument with a cavity, such as an acoustic guitar, is divided into two in the axial direction, and a groove is located at a position symmetrical in the axial direction at the center of both division surfaces. A split endpin that is characterized by having a hollow structure when both are combined. Multiple recesses are provided on one of the split surfaces of the two divided endpins to form a split endpin female, and the same number of protrusions are provided on the other symmetrical surface to form a split endpin male. The split endpin according to claim 1, wherein the split endpin is characterized in that the strength of the holding device for suspending the guitar can be maintained to a certain extent while preventing the guitar from shifting.
