Abstract
The utility model discloses a bass bar of a music instrument. The utility model aims to provide the bass bar which can improve musical quality of a wooden musical instrument. The bass bar is composed of a bass bar body and grooves. The bass bar of the musical instrument is characterized in that: the bass bar body is an elongated wooden bass bar; a plurality of grooves which are uniformly separated from one another by equal distance are engraved on the front surface and the back surface of the bass bar body through a laser engraving machine; and the thickness of each groove is 0.1-3mm. The grooves on the front surface and the back surface of the bass bar body effectively reduce foreign sound which is generated by irregular sound wave, so that the sound is more clear and the musical quality of the wooden musical instrument is improved. Simultaneously, the whole weight of the bass bar is reduced through carbonizing after laser cutting on the front surface and the back surface of the bass bar, and a better sound guiding effect is obtained.
Description
Technical field
The utility model belongs to the parts in a kind of woody musical instrument resonant tank, is specifically related to a kind of sound beam of musical instrument.
Background technology
Traditional sound beam surface is without technical finesse, the wooden softness in surface, position that is used for the reflect sound effect, area is limited, sound is concentrated relatively not after the flat surface reflection of light, to the reflection of sound, conduction causes certain retardance, limit to the resonance of soundboard and the sympathetic response of casing, do not reached desirable tamber effect; And traditional sound beam is heavier, is unfavorable for leading note.
The utility model content
The utility model provides a kind of sound beam of musical instrument.The purpose of this utility model is to optimize the manufacturing technology of existing sound beam, the limitation of the sound beam effect effect that breaks traditions, provide a kind of surface harder, to the reflex of sound wave with to the sound beam with better function of panel leading note, its quality is lighter, the surface is more careful attractive in appearance, and this musical instrument sound beam can strengthen the sympathetic response degree of woody musical instrument resonant tank, effectively improves instrument tamber quality and musical instrument class.
For achieving the above object, the utility model adopts following technical scheme: a kind of sound beam of musical instrument is comprised of sound beam main body (1) and groove (2); It is characterized in that: described sound beam main body (1) is the wooden sound beam of strip; Described sound beam main body (1) front surface (1-1) passes through laser engraving machine carve spacing some grooves (2) uniformly with rear surface (1-2); The degree of depth of described groove (2) is 0.1mm～3mm.
Two ends, left and right, described sound beam main body (1) top are opened respectively and have been cut upper surface (1-3) and (1-4).
Advantage of the present utility model: 1, the utility model has effectively strengthened the hardness of front and rear surfaces after by the laser burning and cutting, strengthens the sound beam to the reflection of sound wave; Strengthen the sympathetic response of musical instrument casing, weaken noise, alleviate sound beam weight, improve bond strength, and make that the surface of sight line contact range is more careful neatly texture.
2, rational groove has enlarged the surperficial area that resonates of sound beam, adds the forte beam to the function of soundboard leading note, thereby strengthens casing sympathetic response degree.
3, sound beam front and rear surfaces by the laser burning and cutting after carbonization alleviated sound beam overall weight, make it that better leading note effect be arranged.
4, the sound beam is compared with original sound beam after processing by the front and back side surface, and sight line contact range surperficial wooden more neatly careful shows the texture of timber, is conducive to improve the class of musical instrument product.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Symbol description in figure: sound beam main body 1, front surface 1-1, rear surface 1-2, groove 2.
Embodiment
The below is described in detail the utility model with best embodiment.
In this enforcement, a kind of sound beam of musical instrument is comprised of sound beam main body (1) and groove (2) with reference to Fig. 1; It is characterized in that: described sound beam main body (1) is the wooden sound beam of strip; Described sound beam main body (1) front surface (1-1) passes through laser engraving machine carve spacing some grooves (2) uniformly with rear surface (1-2); The degree of depth of described groove (2) is 0.1mm～3mm.
Different from original sound beam is: two ends, left and right, sound beam main body (1) top are opened respectively and have been cut upper surface (1-3) and (1-4).The centre is not opened and is cut the surface, and front and rear surfaces is fined away by interposition above sound beam main body (1).
It should be noted that at last: obviously, above-described embodiment is only for the utility model example clearly is described, and is not the restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.And the apparent variation of being amplified out thus or change still are among protection domain of the present utility model.
Claims (2)
1. the sound beam of a musical instrument is comprised of sound beam main body (1) and groove (2); It is characterized in that: described sound beam main body (1) is the wooden sound beam of strip; Described sound beam main body (1) front surface (1-1) passes through laser engraving machine carve spacing some grooves (2) uniformly with rear surface (1-2); The degree of depth of described groove (2) is 0.1mm～3mm.
2. a kind of sound beam of musical instrument as claimed in claim 1, is characterized in that, two ends, left and right, described sound beam main body (1) top are opened respectively and cut upper surface (1-3,1-4).
