A guitar has a sound box with a fingerboard (4) terminating in a scroll with tuning pegs. The tuning pegs tension strings that are fixed to a bridge (7) anchored on the sound-box. The bridge (7) is linked to the sound-box upper deck (2) by a supplementary sound board (9).

Description

Plucked string instrument

Technical field

The present invention relates to a kind of plucked string instrument, guitar for example, comprise a resonant tank that has a panel, a neck that links to each other with resonant tank and some securable, across the string between resonant tank and the neck, these string one ends are fixed in the shared bridge on the resonant tank panel, and the other end is fixed on the neck.

This plucked string instrument, with by the sonorific bowed stringed instrument of the constant shock pulse that contacts with in the orchestra of playing, aspect volume, be in a disadvantageous position because for plucked instrument, very brief playing only produces a very brief pulse.

Background technology

File CH135499C has described one than technology early.Morning, technology only related to bowed stringed instrument for this, did not belong to same class with the present invention.For bowed stringed instrument, string as the ingredient that is separated from each other on the space, is determined trend by the carriage and the chord-drawing plate that are positioned on the resonant tank.Here chord-drawing plate is to be used to make the direction of string trend along carriage, and self-supporting is on the panel of resonant tank.Suitable shape described carriage is positioned at the fringe region of resonant tank, and in most cases to encase fringe region, so that the tension force of string is directed to resonant tank.According to known file, for all types of bowed stringeds instrument, pad or the toning board that should ad hoc form by other materials of a usefulness are loaded onto the chord-drawing plate that is used to guide string on the soundboard of musical instrument, to improve the tone color of musical instrument string.The chord-drawing plate pad can be the small panel of circular, oval-shaped, long rectangle or other shapes.

File DE20113495U1 discloses a nearer technology relevant with the present invention, comprises that both being used for bowed stringed instrument has the soundboard that can be used for plucked string instrument, and with the complete wooden soundboard of making of the traditional fabrication method, this soundboard should be able to produce better tonequality.

Can know from this file, in two soundboards of resonant tank at least one is to make with the method for making of fiber compound structure, described soundboard is made up of a core and the long fibre coating on one or two outside surface of this core, and its medium staple fibre is to be embedded in the carrier material.Described core has a blank that material area surrounded that core arranged at least in the surface of being delimited by the profile of soundboard.This blank can reach the core that fills up with material cumulative volume 80%.

Summary of the invention

Yet the measure of advising in the above-mentioned file does not improve the acoustic radiating of plucked string instrument.

Based on this reason, task of the present invention is, improves the acoustic radiating that is produced by plucked string instrument aspect volume and tonequality.

According to the present invention, above-mentioned task is achieved in that bridge is positioned in the toning board that is formed at panel, and this toning board has the littler thickness of ratio panels.

For plucked string instrument and bowed stringed instrument, sound is that the string by vibrations produces and is strengthened by resonant tank.For this reason, resonant tank should have relatively large quality, so that resonant tank shows an inertia mechanism.On the contrary, according to the present invention, toning board is based on its lighter vibrations quality and shakes, and can obtain the clear separation of sound like this, and wherein the vibrations of toning board are set out by string and excited through bridge.Almost loss-free shock transfer from the string to the toning board has only by shared bridge is placed on the toning board and just may realize.

An one less vibrations quality and a favourable vibrations behavior is effectively to realize with respect to panel or the less thickness of whole resonant tank by toning board.Normally, the thickness of panel is 2.5mm, and with respect to this thickness, according to a preferred embodiment of the present invention, the thickness of toning board should be 0.8mm-1.6mm.When the thickness of toning board is 1.4mm, can reach good especially audio.The thickness of toning board can not rely on the material thickness of panel with selection of constant.

When making plucked string instrument, the size of toning board may have influence on audiorange.Bigger toning board can produce lower sound, can realize higher sound and have the less toning board of physical dimension.Therefore, in view of after the playable audiorange of plucked string instrument, the physical dimension of toning board is a half-way house, it should cover from 800Hz to 15, the audiorange of 000Hz.

In an advantageous embodiments, toning board is to be made of domes that outwards protrude.Plucked string instrument, different with bowed stringed instrument, an end of its string is fixed on the panel of resonant tank rather than is only supported.By like this, not only there is the contact pressure of a vertical direction to act on toning board, and also has by string and act on the pulling force of bridge and the heeling moment that produces, toning board must stop this moment.This moment will cause the side in the introducing of bridge acting force, and the contact pressure of toning board increases, and at the extra pulling force that increases of opposite side.Under the situation of pre-tensioning 500 newton commonly used and the lever ratio of using always, the height difference of the string application point on the Yin Qinma, Shi Erhui produces on toning board and may make bridge embed the power of thin toning board.This problem can be dealt with by the thickness that increases toning board, but can weaken the positive characteristics of the tonequality aspect of toning board like this.Because the domes of the outside protrusion of toning board, acting force can outwards draw away by the flank of domes, so just can adopt thin toning board, and further improve tonequality characteristic and acoustic radiating therefrom.

Preferably, toning board can paste into panel.The enclosed combination of consequently a kind of material, by toning board equably, sticking in large area tying up on the panel.Alternatively, toning board also can be attached on the panel.

For the manufactured materials of toning board, can pay the utmost attention to timber or plastics.If employing timber then should use solid wood, such as China fir or other needlebush.

Adorn a support in the bottom surface of toning board, verified is very favourable.This angle brace is being compared the additional support with less quality place as toning board with the thicker solid toning board of set gross thickness.

Described support can be made of grid, and especially advantageously these grid shapes are right angles.The right angle grid is meant many cross one another supports, and these supports are the angle of intersection with about 90 degree.

Preferably, grid comprises the bridge that the thick both sides of many center sections are thin.West India cork wood is particularly suitable as the material of these bridges.These bridges are affixed on the whole bottom surface of toning board.Preferably, the side edge of these bridges and toning board, but not overlapping, like this can be so that packing into of toning board is easy.

On these bridges, can be coated with the last layer carbon fiber.Carbon fiber especially will be applied to a side that deviates from toning board.The thickness of carbon fiber coating can remain unchanged along the length overall of bridge.

More advantageously, make the texture of these bridges and toning board wood or angled with the texture of panel.By like this, can be so that toning board obtains reinforcing in the less direction of the intensity of timber own.

For the plucked string instrument of panel, can make the texture of panel wood parallel with the grain direction of the toning board of usefulness timber manufacturing with usefulness timber manufacturing.Needlebush, especially China fir can be used as the preferred timber kind of panel equally.Toning board can be with same timber manufacturing.Because the vibrations behavior of mechanical load ability and timber depends on the trend of texture, the texture of the trend of lumber fibre just, so toning board trend should be consistent with the texture trend of panel.The interruption of texture can obviously improve the tonequality characteristic between toning board and the panel.

Embodiment

The present invention will further be set forth by following five accompanying drawings.

Fig. 1 is a front perspective view, and a guitar 1 according to the invention has been described, it has a resonant tank 3 and coupled neck 4.String 5 moves towards the latter end of neck 4 from resonant tank.On resonant tank, an end 6 of string 5 is fixed on the shared bridge 7.The tuner of guitar 1 realizes that by peg 23 other end 8 of string 5 is received in respectively in this peg, and every string 5 is aligned to have corresponding separately tension force by this peg.

Resonant tank 3 comprise one in the bottom surface 26, the sightless sympathetic response base plate 24 of Fig. 1 and one and its outward flange vertical stand-up around sympathetic response side plate 25.In the above 27, resonant tank is the panel involution that has sound hole 28 openings by.

As can be seen, toning board 9 is embedded in 2 li of panels, and shared bridge 7 is fixed on this toning board.Toning board 9 is oval-shaped, and bridge 7 is positioned in the zone line of toning board 9.

Fig. 2 has illustrated the longitudinal sectional drawing of guitar 1.It is one dull and stereotyped and flush with panel 2 on 27 in the above that the toning board 9 here is made into.The thickness 11 of thickness 10 ratio panels 2 of toning board 9 is obviously little.

The fixing of toning board 9 can at first be placed the position of toning board and cut a hole by bonding realization on panel, mill out an annular groove 29a then on this hole.The degree of depth of groove 29a, from top 27, the thickness with toning board 9 matches basically.

Fig. 3 has used the view description identical with Fig. 2 one guitar 1, but different be that toning board 9 is not to paste among the groove 29a, but directly be attached on the panel 2 by an adhesive surface 29b.

Fig. 4 has described a guitar 1 with a longitudinal sectional drawing equally.But the shape that shows with Fig. 2 and Fig. 3 is different, and the toning board 9 here is not to be made into writing board shape, but has domes 12 that outwards protrude.Domes 12 are that each limit evenly forms relatively, bridge 7 is positioned in zone line, so that will be directed to two

flank

30a, 30b towards the contact pressure of sympathetic response base plate 24 directive effects, and the support conical surface by forming by

flank

30a, 30b, a bridge shape or domes will be produced.

In addition, Fig. 4 has clearly demonstrated the thickness 10 and the thickness 11 of panel 2 and toning board 9 with a partial enlarged drawing.Toning board 8 is in groove 29a, is adhesively fixed on panel 2 with circumferencial direction.Because the outside domes that protrude, toning board protrudes from panel 2.

Fig. 5 has described a resonant tank 3 of settling a toning board 9 on panel 2 with a front perspective view that amplifies.At the back side 13 of toning board 9, loaded onto the support of representing with the line segment that cuts off 14.Support 14 has the regular shape of a grid 15, and grid 15 is by bridge 16a and horizontal bridge 16b form longitudinally.These bridges 16a and bridge 16b intersect with an angle of 90 degrees and extend to the edge of toning board, but are no more than the edge.

For the guitar 1 that Fig. 5 shows, the resonant tank 3 and the toning board that have panel 2 are all made by timber.Texture 22 with mark 22 illustrated panels 2 is the direction that extends axially that is parallel to string 5 basically, and the texture 21 of wooden toning board 9 too.The tonequality advantage of guitar 1 according to the invention is the interruption by xylogen, the consistent and generation of the direction that also has texture 21 and texture 22.

Fig. 6 has shown a toning board, the support 14 that this toning board has domes 12 and forms with grid at toning board 9 back sides 13 1.In Fig. 6 view, horizontal bridge 16b is visible in the whole width of toning board 9.In discontinuous interval, bridge 16b is become the bridge 16a of 90 degree trends to pass by five with it.Bridge 16a is structurally identical with bridge 16b.The thickness of

bridge

16a, 16b reaches maximum at zone line, hereinto between the distance of regional domes and the panel 2 that is not shown at Fig. 5 also reach

maximum.Bridge

16a, 16b extend and end at a light filling bar respectively to both sides equably.In the side away from toning board,

bridge
