Description
Technical field
The utility model relates to the musical instrument Wooden Fittings, and especially piano is made the field with the string code system.
Background technology
Piano comprises bass string sign indicating number and alt string sign indicating number with the string sign indicating number.Existing bass string sign indicating number by the sign indicating number bridge, connect firmly the sign indicating number on the sign indicating number bridge and the filler strip that connects firmly below the sign indicating number bridge constitutes.The sign indicating number bridge is made of hardwood (as beech, maple etc.) or hardwood plywood, filler strip adopts hardwood to make equally, alt string sign indicating number generally has whole string sign indicating number and is connected the string sign indicating number and (is about to middle and high sound string sign indicating number and is divided into two sections, place at middle register and treble stepping, below with thin hardwood plate, connect together as edges such as look wood, numb grain wood, it also plays the effect of whole string sign indicating number) two kinds, the two all is to adopt hardwood to make.There is following problem and shortage part in above-mentioned string sign indicating number: the piano allow of compositions such as soundboard sent in, bass sound is thin and " drying " is impure, lacks mellow and full thick and heavy sense.Its reason is, soundboard itself is a vaulted sheet material that radius is very big, and the piano string sign indicating number is close on the curved surface of soundboard, and the string sign indicating number is delivered to vibrations of strings on the soundboard, makes the soundboard vibration, empathizes, and makes the piano sounding.And existing medium-to-high grade piano soundboard has the trend that adopts the quarter sawing dragon spruce to make lining.Because the bass string sign indicating number all is to be close to transmitting vibrations with hardwood mutually with soundboard dragon spruce cork with high pitch string sign indicating number, thereby the effect of string sign indicating number " filtration " acoustic energy is bad, will inevitably produce not conform to humorous sound, and is especially more remarkable in middle basso.
The utility model content
The purpose of this utility model provides a kind of Composite piano string bridge, and it has in the absorption, the pure tone effect of bass area noise.
Be used to realize that the technical scheme that absorbs the bass area noise is: a kind of piano bass string sign indicating number comprises a yard bridge; Connect firmly the sign indicating number on the sign indicating number bridge; Connect firmly the filler strip in the Ma Qiao bottom surface, it is characterized in that, the thickness of the filler strip that described employing dragon spruce is made is 3-15mm; Described sign indicating number bridge is quarter sawing dragon spruce solid wood plate or two-layer above quarter sawing dragon spruce solid wood composite board.
Be used to realize that the technical scheme that absorbs the middle register noise is: a kind of piano alt string sign indicating number, comprise the high pitch string sign indicating number and the middle pitch string sign indicating number that connect as one, it is characterized in that, be inlaid with the dragon spruce filler strip from its outer end part on the bottom surface of described middle pitch string sign indicating number.
Technique scheme shows that the sign indicating number bridge of bass string sign indicating number adopts quarter sawing dragon spruce solid wood plate or composite plate, and filler strip adopts dragon spruce to make, and inlays the dragon spruce filler strip on the middle pitch part bottom surface of alt string sign indicating number.Therefore, the material of above-mentioned string sign indicating number and the soundboard panel be close to it is consistent, does not just have inharmonious noise when producing resonance and occurs, and can play the pure tone effect that absorbs noise, makes in the piano, bass is simpler and more honest mellow and full; One of material cause the two vibration more synchronously, harmonious more, can play and filter sound, increase amplitude, add the effect of strong resonance sympathetic response.
