Description

Multifunctional guitar bridge

Technical Field

The utility model relates to a musical instrument accessory technical field especially relates to a multi-functional guitar musical instrument bridge.

Background

The guitar bridge comprises a fixed bridge, a single-rocker bridge and a double-rocker bridge. The tailpiece for fixing the bridge is fixed on the body, the structure is simple, the stability is good, the strings are easy to adjust, and the shortcoming is that the tension of the strings can not be changed during playing to send out tremolo effect with variable height. The tailpiece bottom of the single-rocker bridge is attached to the body of the musical instrument, the front side of the tailpiece, which is close to the head of the musical instrument, is supported by the support column, the bottom of the tailpiece is provided with the tension spring plate and is tensioned and fixed by the tension spring, the rear side of the tailpiece can slightly tilt, and the handle is utilized to drive the rear side of the tailpiece to slightly tilt so that the strings are relaxed to achieve the purpose of reducing string sounds. The single-rocker bridge can only reduce the string sound, the variation amplitude of the string sound is small, and the generated tremolo effect is limited. The dual-swing bridge sets up the tailpiece to the suspension state, and the tailpiece utilizes the support column to support near the front side bottom of headstock, and the tailpiece bottom sets up the tailpiece board and utilizes the extension spring taut, and the tailpiece reaches the suspension balanced state through the pulling force of string and the pulling force balance of extension spring, utilizes the handle to drive the tailpiece tilt around, makes the string relax or taut, reaches the purpose that reduces the string sound or rise the string sound, and then plays rich changeable music melody. The double-rocker bridge can change pitch over a larger range, but is much less stable. The tailpiece atress condition of two strings of a tremolo bridge among the prior art is shown in fig. 1, because the swing strong point setting of tailpiece is in the position that is less than string sign indicating number and string, the tailpiece can the perk that makes progress in the rear side under the effect of string pulling force, at this moment, must utilize extension spring and extension spring board to hold the tailpiece, make the string keep balanced state with the pulling force of extension spring, just can make the tailpiece that is in the suspended state keep stable, can break this kind of balance to the adjustment of every string when the tuning, many strings need adjust many times repeatedly and just can reach this kind of balanced state, the tuning degree of difficulty has improved greatly, the accommodation process is wasted time and energy. If a string is broken, the total tension of the string changes, the tension balance between the string and the tension spring is broken, the pitches of all strings change, and the playing cannot be continued. Therefore, there is a need to provide a new multi-functional guitar bridge to solve the above-mentioned technical problems.
