Technical Field

The invention relates to the field of musical instruments, in particular to a bridge type mute of a violin.

Background

Training in the performance of musical instruments often produces loud sounds which, if made by beginners or hands, tend to be intolerable to bystanders. In cities, ordinary families are difficult to be specially provided with sound insulation rooms and specially used for musical instrument training. For example, when a violin is exercised, noise is generated, the rest of other people is affected, and the violin is not skilled every day from the beginning, and the violin is not exercised well and the neighborhood is empty. Therefore, a violin with small sounding loudness is needed, which can emit appropriate sound intensity when the violin is exercised, can achieve the sound intensity needed by an exerciser, and can not affect the rest of other people.

However, in the low-loudness violin on the market, the working principle is to reduce the vibration amplitude of the strings through the flexibility of the mute material, and the reduced vibration amplitude of the strings is still directly transmitted to the face with the highest sound production efficiency, so the actual mute effect is poor.

Disclosure of Invention

In view of the above, it is desirable to provide a bridge type mute and a low-loudness violin for a violin in addressing at least one of the problems mentioned above.

The invention provides a bridge type mute of a violin, which is arranged on the violin and comprises a bridge span with a symmetrical structure, wherein a string supporting groove is arranged at the top end of the bridge span, and limiting convex bamboo shoots with preset lengths are arranged at two ends of the bridge span;

In the prior art, a bridge structure 10 of a violin is, as shown in fig. 1, composed of string supporting grooves 11 for supporting strings 20, a bridge deck, and legs 12. As shown in fig. 2, the body 30 is constituted by a deck 31, a back plate 32, side plates 33 on both sides, and the like, and the bridge structure 10 is provided on the deck 31 via a foot surface 31 a.

When the violin is played normally, the strings 20 vibrate due to the friction between bowstrings and the strings 20, then the bridge supporting the strings 20 transfers the vibration of the strings 20 to the piano face 31 through the vertical feet 12, as shown in fig. 3, the piano face 31 drives air to finish resonance in the piano box, and then sound is efficiently transmitted through the piano face 31, the piano back and the piano holes with large areas. Therefore, the vibration of strings 20 is transmitted to the large-area piano face 31 with high sound production efficiency by the bridge supporting the strings 20 through the vertical legs 12, and the path of the transmitted vibration is the key of high sound production loudness of the violin during regular playing.

The invention provides a bridge type mute of a violin and a low-loudness violin, and aims to solve the technical problems in the prior art.

The technical solution of the present invention and how to solve the above technical problems will be described in detail with specific examples.

The embodiment of the first aspect of the present invention provides a bridge type mute of a violin, which is arranged on the violin, as shown in fig. 4 and 5, and comprises a bridge span 100 with a symmetrical structure, wherein a string supporting groove 110 is arranged at the top end of the bridge span 100, and limiting convex bamboo shoots 120 with a preset length are arranged at the two ends of the bridge span 100; the bridge span 100 is suspended on the violin surface 31, and at least part of the side end surfaces of the limiting convex bamboo shoots 120 facing the bridge span 100 respectively abut against the two side end surfaces of the violin, namely part of the side end surfaces abuts against the side plates 33 of the violin. The side end surface of the limiting convex bamboo shoot 120 facing the bridge span 100 can be called as the inner side surface of the limiting convex bamboo shoot 120, and the violin is arranged between the limiting convex bamboo shoots 120 at the two ends of the bridge span 100.

The limiting convex bamboo shoots 120 at the two ends of the bridge-type mute are used for hooking the edges at the two ends of the piano box and can play a role in determining and fixing the position of the bridge-type mute above the piano face 31.

According to the bridge-type mute of the violin, which is provided by the invention, the mute is designed to be a bridge structure which can transmit the vibration of the strings 20 to the side plate 33 with the lowest sound production efficiency of the violin sound box through the bridge span 100 which is arranged across the violin face 31, so that the vibration of the strings 20 is transmitted to the panel with the highest sound production efficiency of the violin sound box, the expansion effect of the face 31 on the vibration of the strings 20 is greatly reduced, the sound heard by a player mainly comes from the strings 20, the loudness of the sound emitted by the violin box is greatly reduced, and the interference of other people when the violin is exercised is avoided.

Alternatively, in certain implementations of the first aspect embodiment, as shown in fig. 4, the bridge span 100 has an upper arched surface and a lower arched surface, the string support groove 110 being provided at the apex of the upper arched surface, the lower arched surface facing the face 31 of the violin.

Optionally, with reference to the embodiment of the first aspect and the foregoing implementation manners, in another implementation manner of the embodiment of the first aspect, as shown in fig. 5, a supporting surface 130 with a predetermined width is disposed between the inner side surface of the limiting protrusion 120 and the side end edge of the lower arched surface, and the bridge span 100 further abuts against the edge rib of the piano surface 31 through the supporting surface 130. The inner side surface of the limit convex bamboo shoot 120 is the side surface of the limit convex bamboo shoot 120 facing the middle of the bridge span 100, the edge of the violin surface 31 close to the side plate 33 is generally provided with a convex rib, and the bridge span 100 abuts against the convex rib through the supporting surface 130, so that the contact between the bridge span 100 and the body 30 can be reduced as far as possible. The slightly wider supporting surfaces 130 at the two ends of the bridge type mute can more firmly arrange the bridge type mute on the body 30, and can play a role of stably jacking the strings 20 of the bridge type mute.

Optionally, with reference to the embodiments of the first aspect and the foregoing implementation manners, in other implementation manners of the embodiments of the first aspect, as shown in fig. 6 and 7, the width of the top end face of the bridge span 100 gradually increases from the middle of the bridge span 100 to both ends.

With reference to the embodiments of the first aspect and the foregoing implementation manners, in other implementation manners of the embodiments of the first aspect, as shown in fig. 8, the width of the limiting protrusion 120 is greater than the width of the top end surface of the bridge span 100.

By providing the transverse structure (i.e., the bridge span 100 from one end of the restraining protrusion 120 to the other end of the restraining protrusion 120) and the vertical structure (i.e., the bridge span 100 from the top end to the bottom end) of the bridge span 100 as the above-described structures, the structure of the bridge span 100 can be simplified as much as possible.

In the aspect of the influence on the timbre, the bridge type mute provided by the invention reduces the volume by changing the vibration transmission path of the strings 20, and in the aspects of the material and mechanical relationship between the string supporting grooves 110 on the mute and the strings 20, the bridge type mute is completely the same as a common bridge, and the problem of changing the frequency balance does not exist, so that the original timbre of the violin is not changed completely when the bridge type mute is used, and only the volume of the violin is reduced.
