擦弦楽器であるバイオリンなどの音量は、集合住宅では消音器を装着しなければ隣家にとって迷惑なレベルであるため、すでに練習用の消音器は数種商品化されている。市販品は、主として駒に装着し駒の振動を押さえる方式のもので、金属製のもの、ゴム製のもの、また、金属をゴム覆ったものがある。f字孔を塞ぐ方式のものは、先行出願はあるものの商品化されているものは市場には見当たらない。 Since the sound volume of bowed stringed instruments such as violins is at a level that disturbs neighbors if they are not equipped with mufflers in collective housing, several types of mufflers for practice have already been commercialized. Commercial products are mainly of the type that is attached to the bridge to suppress the vibration of the bridge, and there are metal ones, rubber ones, and metal covered with rubber. Although there are prior applications for f-shaped holes, there are no commercially available products on the market.

駒に装着する方式の消音器の使用時の課題として、金属製のものは減音効果は高いものの重量があり、脱着時に駒や楽器を痛めるリスクがあり取り扱いに注意を要する。金属をゴムで覆ったものは金属製と同程度の減音効果があり楽器を傷つけるリスクは低いものの、弓が弦に触れる箇所がブラインドとなり演奏のセルフチェックに難がある。そして金属製および金属をゴムで覆ったものは装着時に楽器が重くなり、音質も大きく変わる。一方、ゴム製または樹脂製のものは軽量で取り扱い容易で楽器を傷つけることはないものの減音効果は低い。f字孔を塞ぐ方式のものは、商品として存在せず減音効果は不明であるが、先行出願では消音器を楽器に固定するためのものが別に必要な方式となっている。解決しようとする課題は、軽量で楽器に傷を与えるリスクの少ない脱着容易な消音器にすることである。 As a problem when using a muffler that is attached to a bridge, a metal silencer has a high noise reduction effect, but is heavy, and there is a risk of damaging the bridge and the instrument when attaching and detaching it, so care must be taken when handling it. Metal covered with rubber has the same sound reduction effect as metal and has a low risk of damaging the instrument, but the part where the bow touches the strings becomes a blind, making it difficult to self-check the performance. Metal instruments and metal covered with rubber make the instrument heavy when worn, and the sound quality changes greatly. On the other hand, those made of rubber or resin are lightweight, easy to handle, and do not damage musical instruments, but have a low sound reduction effect. There is no commercial product that closes the f-shaped hole, and the sound reduction effect is unknown. The problem to be solved is to provide a lightweight muffler that is easy to attach and detach with little risk of damaging the musical instrument.

本考案は、擦弦楽器の左右のf字孔をそれぞれ覆う消音器の基盤をソフトレザー(ヌメ革)とし、楽器に接する裏面側に、薄い鉛シールを貼り、その上からメラミン樹脂発泡体(メラミンスポンジ)を接着し、当該メラミンスポンジの周囲を囲むようにして人工皮革(スウェード調)の平型の紐をソフトレザー及びメラミンスポンジと接着し、そのメラミンスポンジと人工皮革を覆うようにフェルトを接着することによりソフトレザーとフェルトでメラミンスポンジを挟み人工皮革で周囲を補強する構造とし、消音器の楽器に接する面側のf字孔の中央部分と端の円形部分の2カ所の位置にf字孔に挿し入れる凸形状部位を備え、そのうちf字孔の中央部分に挿し入れる凸形状部位のコルクにメラミンスポンジを貼りフェルトで覆いコルク部分をソフトレザーに接着し、f字孔の端の円形部分に挿し入れる部位は、コルクをフェルトで覆いコルク部分をソフトレザーに接着し、2カ所の凸形状部位で当該消音器の位置を固定し、f字孔の中央部分挿し入れる部位のメラミンスポンジの弾力により当該消音器を楽器に密着させる構造とし、合計重量約20gと軽量で、脱着容易なことを特徴とする。 This invention uses soft leather (tanned leather) for the base of the muffler that covers the left and right f-shaped holes of the bowed stringed instrument, and sticks a thin lead seal on the back side that comes into contact with the instrument, and melamine resin foam (melamine) Sponge), a flat string of artificial leather (suede-like) is adhered to the soft leather and melamine sponge so as to surround the melamine sponge, and felt is adhered so as to cover the melamine sponge and the artificial leather. The structure is such that the melamine sponge is sandwiched between soft leather and felt, and the surroundings are reinforced with artificial leather. It has a convex part to be inserted, and a melamine sponge is attached to the cork of the convex part to be inserted into the center part of the f-shaped hole. The part where the cork is inserted is covered with felt and the cork part is glued to the soft leather. It has a structure in which the muffler is brought into close contact with the musical instrument, is light in weight with a total weight of about 20 g, and is easy to attach and detach.

上述の様に、本考案はその素材にメラミンスポンジ、フェルト、コルクを使用しており、共に軽量で吸音効果があり加工性が良い。また、ソフトレザーの裏に貼った鉛シールは防振効果とともに可塑性があるため消音器を装着する楽器の形状にフィットさせる。フェルト素材は楽器表面のニスに優しい。楽器への装着は、f字孔に消音器の2つの凸部位を差し入れ、2カ所で消音器を固定する形式で、簡単で脱着容易である。また、消音器が左右に分割されるためサイズ的にもコンパクトになり、楽器ケースにも収納可能となる。音の減衰効果については、約7デシベルの減音効果が認められ、特にf字孔を塞ぐことで低音部の減音効果があり、音質的にも雑音が減少するため音程が取り易くなる効果がある。 As described above, the present invention uses melamine sponge, felt, and cork as its materials, all of which are lightweight, sound absorbing, and easy to process. In addition, the lead seal attached to the back of the soft leather has a vibration-proof effect and plasticity, so it fits the shape of the instrument to which the silencer is attached. The felt material is gentle on the varnish on the surface of the instrument. Mounting to the musical instrument is simple and easy to attach and detach, by inserting two projections of the muffler into the f-shaped holes and fixing the muffler at two points. In addition, since the muffler is divided into left and right, it is compact in size and can be stored in a musical instrument case. Regarding the sound attenuation effect, about 7 decibels of sound reduction effect is recognized, and especially by closing the f-shaped hole, there is a sound reduction effect in the bass part, and in terms of sound quality, noise is reduced, making it easier to tune. There is

消音器の重量を軽くして減音効果を高めることをf字孔を塞ぐ方法にて行うために強度・耐久性のあるレザー(皮革)及び人工皮革(スウェード調)を使用するとともに吸音素材であるメラミンスポンジをクッション材として使用することにより楽器と消音器との密着性を高め、消音器の凸形状部とf字孔との摩擦によって消音器を固定し、鉛シールを貼ることにより消音器自体の振動を押さえ総合的に減音を実現した。 In order to reduce the weight of the muffler and enhance the sound reduction effect by closing the f-shaped hole, we used strong and durable leather (leather) and artificial leather (suede-like), as well as a sound absorbing material. By using a certain melamine sponge as a cushioning material, the adhesion between the musical instrument and the muffler is enhanced, the muffler is fixed by friction between the convex shape of the muffler and the f-shaped hole, and the muffler is affixed with a lead seal. It suppresses the vibration of itself and realizes overall sound reduction.

本考案は、擦弦楽器のf字孔を被覆し、f字孔からの音の放出を妨げることで減音する方式の消音器に関するものである。 TECHNICAL FIELD The present invention relates to a muffler that reduces sound by covering f-holes of bowed stringed instruments and preventing sound emission from the f-holes.

擦弦楽器の消音器は既に数種のものが存在する。主として駒に装着し、駒の振動を押さえる方式のものであり、素材が金属製のもの、金属をゴムで覆ったもの、ゴム製のものが数種ある。また、市場にはないが、先行出願にf字孔を塞ぐ方式のもの、魂柱の位置を変える方式のものがある。 Several types of mufflers for bowed string instruments already exist. It is mainly attached to the bridge to suppress the vibration of the bridge, and there are several types made of metal, metal covered with rubber, and rubber. In addition, although not on the market, there are prior applications for which the f-shaped hole is closed and for which the position of the sound post is changed.

駒に装着する方式の消音器の使用時の課題として、金属製のものは減音効果は高いものの重量があるため、脱着時に駒や楽器を痛めるリスクがあり取り扱いに注意を要する。金属をゴムで覆ったものは金属製と同程度の減音効果があり楽器を傷つけるリスクは低いものの、駒の上に装着した消音器で弓が弦に触れる箇所がブラインドとなるためボウイングの確認がし難い。そして金属製および金属をゴムで覆ったものは装着時に楽器が重くなるため長時間の使用では疲れ、また音質も相当変わる。一方、ゴム製または樹脂製のものは軽量で取り扱い容易で楽器を傷つけることはないものの減音効果は低い。f字孔を塞ぐ方式のものは、商品として存在せず減音効果は不明であるが、先行出願では消音器を楽器に固定するためのものが別に必要な方式となっている。解決しようとする課題は、駒に装着する消音器と併用して楽器の音量を下げることが可能な軽量で楽器に傷を与えるリスクの少なく脱着容易な消音器にすることである。 As a problem when using mufflers that are attached to the bridge, metal ones have a high sound reduction effect, but are heavy, so there is a risk of damaging the bridge and the instrument when attaching and detaching them, so care must be taken when handling them. Metal covered with rubber has the same sound reduction effect as metal, and the risk of damaging the instrument is low. hard to do Metal instruments and rubber-covered metal instruments make the instruments heavy when worn, so they are tiring to use for long periods of time, and the sound quality changes considerably. On the other hand, those made of rubber or resin are lightweight, easy to handle, and do not damage musical instruments, but have a low sound reduction effect. There is no commercial product that closes the f-shaped hole, and the sound reduction effect is unknown. The problem to be solved is to provide a lightweight muffler that can reduce the sound volume of a musical instrument in combination with a muffler that is attached to a bridge, has little risk of damaging the musical instrument, and is easy to attach and detach.

本考案は、擦弦楽器の左右のf字孔をそれぞれ覆う消音器の基盤をソフトレザー(ヌメ革)とし、楽器に接する面側に、薄い鉛シールを貼り、その上からメラミン樹脂発泡体(メラミンスポンジ)を接着し、当該メラミンスポンジの周囲を囲むようにして人工皮革(スウェード調)の平型の紐をソフトレザー及びメラミンスポンジと接着し、そのメラミンスポンジと人工皮革を覆うようにフェルトを接着することによりソフトレザーとフェルトでメラミンスポンジを挟み人工皮革で周囲を補強する構造とし、消音器の楽器に接する面側のf字孔の中央部分と端の円形部分の2カ所の位置にf字孔に挿し入れる凸形状部位を備え、そのうちf字孔の中央部分に挿し入れる凸形状部位のコルクにメラミンスポンジを貼りフェルトで覆いコルク部分をソフトレザーに接着し、f字孔の端の円形部分に挿し入れる部位のコルクをフェルトで覆いコルク部分をソフトレザーに接着し、2カ所の凸形状部位で当該消音器の位置を固定し、f字孔の中央部分に挿し入れる部位のメラミンスポンジの弾力により当該消音器を楽器に密着させる構造とし、合計重量約20gと軽量で、脱着容易なことを特徴とする。 This invention uses soft leather (tanned leather) for the base of the muffler that covers the left and right f-holes of the bowed stringed instrument, and attaches a thin lead seal to the side that comes into contact with the instrument, and then melamine resin foam (melamine). Sponge), a flat string of artificial leather (suede-like) is adhered to the soft leather and melamine sponge so as to surround the melamine sponge, and felt is adhered so as to cover the melamine sponge and the artificial leather. The structure is such that the melamine sponge is sandwiched between soft leather and felt, and the surroundings are reinforced with artificial leather. It has a convex part to be inserted, and a melamine sponge is attached to the cork of the convex part to be inserted into the center part of the f-shaped hole. The cork in the part to be inserted is covered with felt and the cork part is glued to the soft leather. It has a structure in which the muffler is brought into close contact with the musical instrument, is light in weight with a total weight of about 20 g, and is easy to attach and detach.

上述の様に、本考案はその素材にメラミンスポンジ、フェルト、コルクを使用しており、共に軽量で吸音効果があり加工性が良い。また、ソフトレザーの裏に貼った鉛シールは防振効果とともに可塑性があるため消音器を装着する楽器の形状にフィットさせる効果がある。楽器に接する部分のフェルト素材は比較的柔らかな表板を傷つけず表面のニスを痛めない。楽器への装着は、f字孔に消音器の2つの凸形状部位を挿し入れ、2カ所で消音器を固定する形式で、簡単に脱着できる。また、消音器が左右に分割されるためサイズ的にもコンパクトになり、楽器ケースに収納可能となる。音の減衰効果については、約7デシベルの減音効果が認められ、特にf字孔を塞ぐことで低音部の減音効果があり、音質的にも雑音が減少するため音程が取り易くなる効果がある。 As described above, the present invention uses melamine sponge, felt, and cork as its materials, all of which are lightweight, have a sound absorbing effect, and are easy to process. In addition, the lead seal attached to the back of the soft leather has a vibration-proof effect and plasticity, so it has the effect of fitting the shape of the instrument to which the silencer is attached. The felt material in the part that comes into contact with the instrument does not damage the relatively soft top board and does not damage the surface varnish. The muffler can be easily attached to and detached from a musical instrument by inserting the two convex portions of the muffler into the f-shaped holes and fixing the muffler at two points. In addition, since the muffler is divided into left and right, it is compact in size and can be stored in a musical instrument case.
