Background technique

Guitar trill zither bridge is the common device of stringed musical instrument, by artificial control, changes in the short time of string The corresponding continuous alternate special change in pitch of power variation and sending.

Existing pair is shaken guitar trill zither bridge (floydrose), is the state to suspend when balancing static, is whole by string The active force of body and tension spring force balance reach, by 2 or multiple post adjustment zither bridges being embedded on qin body The edge of a knife of whole height, zither bridge is withstood in the concave ring of column, and column props up zither bridge and carrys out work, due to zither bridge shake when be Hard friction is easy to wear on column and then causes to playback to have some setbacks to influence whole standard pitch, and hard friction also makes whole shake feel It is partially hard.The edge of a knife and the abrasion of column contact point can increase and irreversible when significantly alterring pitch using rocking bar for a long time, also hold So that the column built-in fitting being embedded in inside qin body is loosened deformation, and then influences zither bridge job stability.Since double zither bridges of shaking exist It is easy to cause string to be broken when the stretching string of frequent different range or large force play string when work, because of string Between and between tension spring be balance relationship, any string when being broken this balance be broken, and then remaining string The change that standard pitch is all generated due to tension variations continue qin performance can not.

In addition, it is existing it is double shake guitar trill zither bridge change string, tuning, in terms of there is technological deficiency.

1) in terms of changing string

A. cannot integrally change the outfit string, usually all be independent dismounting (since the tension spring tension and string of trill zither bridge are whole Tension balanced, integral disassembly, assembly will cause zither bridge and collapse, or damage qin body；

B. disassembly screw is easy to slip teeth for a long time for the jacking block of the clamping string device of trill zither bridge；

C. all it is device from thick to thin from high pitch to bass string due to string, holds in string block in most thin high pitch string pressing from both sides It is easy to wait abjection when in use, cause the whole sound that runs to be unable to complete performance, thin string, which curves round be placed in folder string block, can reduce de- string Generation, but beginner is not easy to operate.

Since string is in whole pulling force and zither bridge entirety tension balanced, it is vibraphone that the position of zither bridge and qin body, which maintain an equal level, The optimum state of bridge, on condition that every string requires to be maintained at standard pitch, due between every string, all strings and zither bridge It is the relationship of three's tension balanced between tension spring, so this adjustment process is cumbersome very long, it is a large amount of to consume the tuning time.Traditional The method of tuning a stringed instrument is that a piece old string of disassembly is installing a new string, is then tuned into standard pitch, has several strings to need repetition several The secondary step, because different according to the specification of string, whole thickness is also different, when the string for integrally changing thinner or thicker specification into When, due to string entirety tension variations, zither bridge height have it is different degrees of float up and down, need comparatively laborious debugging With the accuracy in pitch of every string of correction, while being also difficult to adjust the high good octave accuracy in pitch position in the case where empty-chord sound mixes up.

3) resonance aspect

Double zither bridge pulling force that shake are by more tension spring connection zither bridges and qin body, by adjusting the drawing spiral shell between tension spring and qin body What silk was adjusted to complete pulling force, when playing the musical instrument, the vibration of string can pass to tension spring, and tension spring is made to generate resonance, and this resonance is Damage musical sound quality.

4) string is away from adjustment

Traditional pair is shaken zither bridge bridge and is fixed on zither bridge pedestal, therefore individually string is away from that can not adjust, if adjusted String makes whole string away from variation away from the height for being all adjusting post, not can be carried out the subtle adjustment of independent string.

When rotating trill rocking bar 400, trill rotary shaft 401 is moved synchronously, and is driven eccentric block 402 to rotate, is worked as eccentric block 402 rotations rotate as shown in figure 3, eccentric block 402 protrudes one end to rotation lock pressure to when generating interference with rotation lock pressure 303 The location A of power part 302, rotation lock pressure piece 302 are moved around first rotating shaft 308, at the same time, the in first rotating shaft 308 The second torsional spring 306 on one torsional spring 305 and the second shaft 309 starts to accumulate torsion, when the prominent one end of eccentric block 402 is rotated to rotation When the B location of twist lock pressure piece 302, as shown in figure 4, movement is completed, rotation lock pressure piece 302 is pushed open by eccentric block 402 at this time, Because U-shaped rotation lock lock tongue 303 is connect with rotation lock pressure piece 302 by the second torsional spring 306, at this time U-shaped rotation lock lock tongue 303 Accumulation of pressure reaches capacity.There are three types of positions relative to the lock-bit groove 307 on spring frame for U-shaped rotation lock lock tongue 303 at this time:

As shown in figure 5, U-shaped rotation lock lock tongue 303 is at this time when upper plate 102 is relative to 201 forward-lean state of spring frame The accumulation of pressure limit is withstood on the upslope of spring frame lock-bit 304, and string pulling force is greater than the pressure of spring 206 at this time, is passed through Lifting trill rocking bar 400 reaches U-shaped rotation lock lock tongue 303 and locks in the lock-bit groove 307 of spring frame lock-bit 304, at this time for The equilibrium state of zither bridge work, as shown in Figure 7.

As shown in fig. 6, U-shaped rotation lock lock tongue 303 is at this time when upper plate 102 is relative to 201 retroverted state of spring frame The accumulation of pressure limit is withstood on 304 downslope of spring frame lock-bit, and string pulling force is less than the pressure of spring 206 at this time, by pressing Pressure trill rocking bar 400 reaches U-shaped twist lock lock tongue 303 and locks in the lock-bit groove 307 of spring frame lock-bit 304, is at this time zither bridge The equilibrium state of work, as shown in Figure 7.

When U-shaped rotation lock lock tongue 303 is locked in the lock-bit groove 307 on spring frame lock-bit 304, string pulling force etc. at this time It is as shown in Figure 7 and Figure 8 spring 206 and string tension balanced shape for the equilibrium state of zither bridge work in the pressure of spring 206 Figure is cutd open before state cuts open figure with after.

Three kinds of positions are that string pulling force and spring and another spring pressure difference cause, and are shaken by lifting or pressing trill Bar 400 enters U-shaped rotation lock lock tongue 303 in spring frame lock-bit groove 304, and whole zither bridge is made to reach equilbrium position.

In addition, rotation trill rocking bar 400 to original state, eccentric block 402 synchronizes after string is adjusted to the accuracy in pitch of musician's needs Rotation lock pressure piece 302 is screwed out, U-shaped 303 pressure of rotation lock lock tongue is eliminated, by lifting trill rocking bar 400, U-shaped rotation up and down Lock lock tongue 303 is popped up out of lock-bit groove 307, such as Fig. 9, Figure 10, tri- kinds of states of Figure 11, these three state string pulling assemblies 100 enclose When rotating in rotatable space around axis, U-shaped rotation lock lock tongue 303 does not generate any interference with spring frame lock-bit 304, this State is zither bridge counter lock off position, and three kinds of situations are by adjusting worm screw 203 (worm screw and qin rear surface maintain an equal level) band at this time Turbine 202,205 push the spring 206 of spring back plate on synchronous drive turbine spinner handle 204 are moved, and then change pressure to make zither bridge tune It saves to equilibrium state.
