Abstract

<P>PROBLEM TO BE SOLVED: To solve the problems that the conventional damper is hard to attach to the stringed instrument and it makes hard to play on correct tones when attached and further gives uncomfortable feeling on the fingers pressing the strings if attached on the strings. <P>SOLUTION: The high damper effect can be obtained without affecting the touch sense on the strings and the tones by attaching a special sheet for vibration damping on the surface of the front board which mainly generates the sound of the stringed instrument. Further, this special sheet can repeatedly be used by making its one side a suction surface. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a sound attenuator that suppresses the sound volume of a stringed instrument having a sound body such as a guitar, violin, or mandolin without impairing the playing comfort.

  Most of the structures of typical attenuators currently in circulation are those that suppress vibrations of strings by attaching metal, sponge, or rubber attenuators near the lower piece of the strings. Other than this, there is a thing that blocks a sound hole vacated on the surface plate of a musical instrument with a rubber lid.

There is also a silencer with various modifications to the sound drum.

However, the method of attaching a weak sound device directly to a string has the following drawbacks. Because the vibration of the strings is disturbed unnaturally, it gives the player a sense of technical discomfort. If a weak sounder is mounted at a position away from the lower piece for the purpose of enhancing the weak sound effect, the musical instrument's pitch is adversely affected. For stringed instruments, the sound quality is cut off, and only the attack sound when playing a string is heard. In particular, the disadvantages of pitch and sound quality are not allowed from a musical point of view.
Although the sound quality is softened by the method of closing the sound hole, the low sound effect is not so high. This is because it is the vibration of the surface plate that produces the main volume of the stringed instrument, and the volume generated from the sound hole is not so high compared to the volume generated from the surface plate.

  In the case of a muffler with a remodeled soundbox, in addition to the large economic burden of purchasing a new instrument, different instruments are used for public performance and practice. A sound attenuator that can be easily attached to a favorite instrument reduces the economic burden and helps practice efficiency.

  The present invention has been made to overcome the above-mentioned drawbacks, and provides an apparatus capable of obtaining a high low-pitched sound effect while minimizing a sense of incongruity with the performance sensation and affecting the musical instrument's pitch and expressiveness as much as possible. With the goal.

  In order to solve the problem 1, the gist of the present invention resides in a method for efficiently obtaining a weak sound effect by attaching a sheet having a high vibration control effect to a surface plate of a stringed instrument.

  In order to facilitate attachment and detachment to the musical instrument of Problem 2, the vibration suppression sheet is adhered to the suction sheet, and is adhered to the surface plate of the musical instrument on the surface of the suction sheet.

  Due to the action of the first problem solving means, the vibration of the surface plate of the musical instrument is suppressed, and the volume generated from the musical instrument becomes very small. Also, since no foreign object is attached to the strings, the player feels a little uncomfortable except that the instrument is a little heavier. There is no negative impact on the pitch.

  The operation of the second solving means is as follows. The existing vibration suppression sheet can obtain the maximum effect by adhering to a vibrating object without any gap. However, if the vibration suppression sheet is glued to the musical instrument, it cannot be removed. Therefore, after attaching the vibration suppression sheet to the suction sheet, attaching the surface of the suction sheet to the instrument provides the same low-noise effect as attaching the vibration suppression sheet directly to the instrument, and can be easily and repeatedly attached and detached. It becomes possible.

  As described above, the present invention suppresses the vibration of the surface plate, which is the main source of the volume of the stringed instrument, so that natural music expression can be achieved while suppressing the volume.

  Moreover, since the adsorption sheet is used for mounting on the musical instrument, it can be easily and repeatedly attached and detached.

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

  In FIG. 1, reference numeral 1 denotes a vibration suppression sheet obtained by processing urethane or rubber. Reference numeral 2 denotes an adsorption sheet that is attached to a flat surface without using an adhesive. These two types of sheets are stacked and bonded without gaps.

  As shown in FIG. 2, the sheet laminated in the manner shown in FIG. 1 is molded in accordance with the shape of the surface plate of the guitar. Cut off the fingerboard and lower piece. Reference numeral 5 denotes a cut made from the hole of the lower piece part to the edge part so that the attachment and detachment is easy.

  FIG. 3 shows a state where it is attached to a guitar.

Claims (2)

  In a stringed instrument with a sounding drum, this is a low-pitched sound that reduces the volume of the instrument by mounting a vibration-suppressing sheet on the surface plate, which is the main source of volume.   By using a suction sheet that does not use glue or adhesive, it is possible to attach and detach it easily and repeatedly by attaching a sound absorber to the surface plate.
