Description

String end pin {End Pin}

In this invention, when a string instrument such as a cello or double bass is played, vibration or sound is transmitted to the ground through the end pin, resulting in loss of sound or tone. To compensate for these shortcomings, loss of sound or tone was minimized, and a hollow part with a small diameter inside the main hollow part of the end pin was installed in a non-contact method to generate resonance in the small diameter hollow part and reproduce a clear and delicate sound. It is a device that returns to the soundboard of

In general, string instruments (FIG. 1) are used by fixing the soundboard (102) countless times. To produce a clear sound, the soundboard is processed thinly, or to make a heavy sound, the soundboard is processed by adding the thickness of wood. In addition, the end pin was manufactured in the form of a rod or a hollow (pipe), so there was a problem in that the sound or tone was lost in the process of being transmitted to the ground (FIG. 1)-(107). This minimizes sound loss,

A hollow part 501 with a smaller diameter is installed inside the main hollow part (FIG. 6)-(201) in a non-contact (FIG. 6)-(B) method using a set screw to reduce resonance in the small hollow part 501 Then, the clear sound was delivered to the soundboard (Fig. 1)-(102) again for a delicate performance.

the present invention

1) To prevent the loss of tone or tone that is lost to the ground.

2) Through a device that resonates inside the end pin, it resonates with a clearer sound, which improves the performance of the instrument without replacing or repairing the instrument. can diversify

A common endpin is

(FIG. 2) In an integrated method in which the shaft 203 is fixed to the main hollow 201 with a set screw 206, sound and tone are transmitted to the ground well and are lost.

(D) of (Fig. 3) of the present invention inserts the bushing 301 into the main hollow part 201 in a structure that transmits less sound and tone to the main shaft 203 than the fixed method, and 201 of the main hollow part ) load is applied to the arrowhead (800), so the three protrusions (Fig. 4)-(400) are stably applied to the end of the main hollow part, and the closing area is minimized to minimize the transmission of tones and tones to the ground, A washer 302 was installed to eliminate noise between the main hollow part (FIG. 5)-(201) and the arrowhead (FIG. 5)-(800), and a compression spring 501 pushed the washer to prevent noise.

A resonance device was added in the main hollow part (Fig. 6)-(201).

(FIG. 6)-(B) is a hollow part 501 with a small diameter inside the main hollow part 201 in a non-contact manner to generate resonance in the hollow part 501 and produce a clear sound in the resonance plate (FIG. 1)-( 102) to do so.

It is possible to play delicately, and it is possible to increase the expressive power.

An embodiment of the present invention will be described with reference to the accompanying drawings as follows.
1 is a front view of an end pin mounted on a stringed instrument.
Fig. 2 is a cross-sectional view of an arrow portion generally contacting the ground and a main hollow portion;
3 is a cross-sectional view designed to prevent loss of sound and tone to the ground by improving FIG. 2;
4 is a front view with a minimized contact area in order to minimize loss of sound and tone.
Fig. 5 is a partial cross-sectional view in which a compression spring is installed in the contact portion to prevent noise;
6 is a cross-sectional view in which a small hollow part and a main hollow part are fastened in a non-contact manner to generate resonance.

In the conventional method (FIG. 2), a screw hole 205 is formed in the main hollow part 201 toward the center, and a set screw 206 is coupled to the screw hole, so that the main hollow part 201 and the shaft 203 are one. As the body, the yin is lost to the ground. to alleviate this

This invention is

(FIG. 3) - In the cross-sectional view (D), a bushing 301 is inserted into the main hollow 201, and a groove 23 is installed on the shaft to prevent the shaft 203 from leaving, and a stop ring 300 ) to prevent the shaft 203 from being separated. This minimizes the transmission of sound and tone from a fixed method to an indirect contact method,

Since a screw hole 850 is formed in the hollow arrow bundle 800 toward the center and fastened with a set screw 900 , it is designed to support the load of the main hollow part 201 .

(FIG. 4) shows that in order to minimize the contact area, the protrusion 400 is made to contact only three places 400 at the end of the main hollow part 201 to reduce the contact area, so that the sound and tone are directed to the ground through the arrow ball 800. to minimize fall out

(Fig. 5) In order to prevent noise on the contact surface, the washer (302) is pushed by the spring (501) so that there is no vibration.

as a resonance device

(FIG. 6) - The enlarged cross-sectional view (B) is a cross-sectional view for fixing the hollow part 501 with a small diameter inside the main hollow part 201 in a non-contact manner.

A screw hole (C)-(77) is formed toward the center of the small hollow part (501) to make a gap (A) to position the small hollow part (501) in the center of the main hollow part (201),

Adjust the gap (A) evenly with the set screw (700), and after the set screw (600) is positioned in the middle of the two set screws (700) of the small hollow part (501), the screw hole (C)-(66) If it is locked with an asset screw (C)-(600), it passes through the through hole (C)-(55) and presses the point on the opposite side of the through hole (C)-(88) to the main hollow and (B)-(201). ) The small hollow part (B)-(501) is fixed, and the small hollow part (B)-(501) receives the vibration of the bow in the main hollow part (B)-(201) and receives the vibration from the hollow part with a small diameter (Fig. 6). )-(W) The condition to cause resonance and return to the soundboard was prepared.

The device for fixing the hollow part (FIG. 6)-(B) may be installed in at least two places in the main hollow part 201 . If the length of the main hollow part (FIG. 6)-(201) is long, it is possible to install three or more places (FIG. 6)-(B) fixed in the main hollow part 201 with a set screw.
