String pulling assembly of bridge capable of rapidly switching suspension state

The present application is a divisional application entitled "a bridge capable of rapidly switching a floating state" filed on application date 2021, 3/16/3, application number 202120543429.0.

Technical Field

The utility model relates to a guitar bridge technical field especially relates to a but string pulling assembly of fast switch over suspension's bridge.

Background

The bridge is a device commonly used by stringed instruments such as guitars, and can be divided into three categories according to functionality, wherein the first category is a fixed bridge, the second category is a tremolo bridge, and the third category is a bridge capable of switching the suspension state of the bridge, wherein the tremolo bridge is a device which generates corresponding continuous and alternate special pitch changes by controlling the suspension state of the bridge artificially and changing the tension change of strings in a linkage manner.

The existing first type of fixed bridge is a device fixedly installed on a body, most of the fixed bridge is an organization structure of a thread sleeve fixedly embedded in the body and a supporting screw with adjustable height, and the tremolo effect cannot be generated by changing the suspension state of the bridge. The tuning string has the advantages of firm and stable structure, difficult deformation, stable and firm timbre, longer delay, better resonance, fast tuning, fast overall replacement of the string, and no influence on the pitch standard of the cosine of the string after the string is broken. The disadvantage is that it does not produce diversified tremolo effects, and lacks the expressive power of instruments than tremolo bridges, such as Gibson lp and sg fixed bridges.

The working standard of the existing second-type double-swinging guitar tremolo bridge is a balanced suspension state, which is mainly realized by the balance of the acting force of the whole string and the acting force of a spring, two or more main supporting structures are embedded in the guitar body, height-adjustable upright post screws are realized as fulcrum structures, the inner arc-shaped supporting point of the bridge part is clamped in the concave ring of the upright post, and the acting force of the string and the acting force of the spring enable the bridge to suspend to reach the working state. Its advantages are that the organ can generate diversified tremolo effect during playing, and high expressive power of musical instrument. Its shortcoming is that when the tremolo bridge is used to the high frequency, because the position of fulcrum contact is the hard friction relation, produce easily and return the not smooth and easy condition in equilibrium position, and then the relation influences the standard pitch requirement of playing in succession, this kind of structure rocks simultaneously and feels on the hard side, it is bad to play the experience, the long-time single direction atress of stand, there is the tendency of not hard up deformation, influence the stability of bridge, because the structural relation easily produces bad resonance when playing, can not wholly change the string, can not quick tuning, and the fracture of any string can all influence all the other string standard pitches moreover.

The third type is a bridge capable of switching the suspension state of the bridge, for example, a tremolo bridge with a balance lock (publication No. CN212113192U), the suspension state of the bridge can be controlled by a rocker device in the working state, and the whole part is screwed on the body. The piano with the device has the advantages that the working state of the piano bridge can be switched at will when the piano is played, and the fixed state or the suspension state can be modulated according to requirements. The tremolo bridge has the defects that when the tremolo bridge with the design is used, because the structure of the balance lock adopts bidirectional torsion conduction, when the tremolo bridge is locked at a balance position, the situation that the lock tongue is blocked is easily caused due to the pressure difference of the pressure spring, and the tremolo bridge cannot smoothly switch functions; meanwhile, the rocker needs to be screwed into the rotating shaft at an alignment angle, so that the operation requirement is high, and the rocker is not suitable for beginners to operate.
