In addition to guitar materials, guitar shape and structure have a great impact on its tone. In order for the guitar's panel to react quickly to vibration, the thickness of the panel must be thin enough. When a guitar is played, the panel bears strong pulling force, so that the panel is designed and assisted again, the panel is ensured to have enough toughness and strength, otherwise, the panel is collapsed and deformed due to the pulling force. The sound stick can strengthen panel intensity and toughness, effectively prevents the guitar because the subsidence of panel under the tensile effect of string.

The existing guitar on the market is too thick in sound stick design, so that vibration of the resonance box is affected, and resonance and volume of the resonance box are limited to a certain extent; and the design of the sound stick is too thin, so that the guitar is collapsed and deformed.

The second object of the present utility model is to provide a stringed musical instrument which is loud and has a good tone.

One of the purposes of the utility model is realized by adopting the following technical scheme:

the bridge arch type sound stick comprises a main body part and inclined surface parts extending from two ends of the main body part, wherein the inclined surface parts and the main body part form an arch structure, and at least one penetrating through hole is formed in the main body part.

Further, the center line of the through hole is perpendicular to the plane of the side wall of the main body part.

Further, the cross section of the through hole is one or more than two of a circle, a semicircle, an ellipse, a triangle and a polygon.

Further, the through holes are axially symmetrically distributed in the main body part. The utility model can control the number and the proportion of the through holes according to the requirement, preferably, the number of the through holes is 2-20, and the width ratio of the through holes to the width of the main body part is 0.1-0.8:1.

Further, the bridge arch type sound stick is of an integrated structure.

The second purpose of the utility model is realized by adopting the following technical scheme:

a string instrument comprises a resonance box, wherein the bridge arch type sound stick is arranged in the resonance box.

Further, the stringed musical instrument includes a ballad guitar, a classical guitar, a you kriging and a frego guitar.

Further, the sound stick is located at the front panel or the back panel of the resonance box.

Compared with the prior art, the utility model has the beneficial effects that:

according to the bridge arch type sound stick, through the through holes formed in the sound stick, resonance sound generated by the plucked strings circulates in the resonance box through air, so that air resistance is reduced, sound volume is increased, and feedback and sensitivity of the musical instrument are improved.

The string instrument adopts the sound stick with the through holes inside, and has high volume and good tone.

Detailed Description

The present utility model will be further described with reference to the accompanying drawings and detailed description, wherein it is to be understood that, on the premise of no conflict, the following embodiments or technical features may be arbitrarily combined to form new embodiments.

Example 1

The bridge-arch type sound stick 1 is in an integrated structure as shown in fig. 1-2, and comprises a main body part 12 and inclined surface parts 11 extending from two ends of the main body part 12, wherein the inclined surface parts 11 and the main body part 12 form an arch structure, and at least one penetrating through hole 13 is formed in the main body part 12.
