Abstract
The utility model discloses a tone beam of an instrument, comprising a stripy wood tone beam main body. The tone beam main body is provided with a plurality of tone frequency through holes which play a role in effectively reducing the weight of the tone beam. In the tone beam disclosed by the utility model, the structure strength is same as that of the traditional solid tone beam; since the weight of the tone beam is reduced, the elasticity of the tone beam with an instrument panel bonded with the tone beam is greatly enhanced, the tone frequency through holes can lead the area of the side surface of the tone beam to be reduced and lead a tone frequency transfer to be smoother, so that a tone given out of the instrument is thicker and finer. In the tone beam, not only can the weight be reduced, but also the tone frequency vibration effect and the tone color of the instrument are better, and compared with the instrument with the ordinary tone beam structure, the volume and the tone quality of the instrument with the tone beam disclosed by the utility model are greatly improved.
Description
Technical field
The utility model relates to musical instrument spare and accessory parts technical field, relates to a kind of sound beam of musical instrument specifically.
Background technology
The sound beam is a kind of parts of musical instrument, it is a kind of wooden crossbeam that is installed in the stringed instrument resonator, usually glued together with the resonant tank soundboard, the sound beam has the effect of adjusting instrument tamber and support soundboard anticracking, and sound beam of the prior art acts on the resonant tank of consolidating wooden musical instrument usually.The many wide models of sound beam use on wooden acoustic instrument, and material is mainly used pine, European spruce wherein, and Canada Red cdear (Cedar) is best sound beam material, the fish-scale floss in China northeast also is first-class sound beam material.Sound beam of the prior art all is the solid wooden sound beam of strip, when reaching the frame thing intensity that supports instrument panel, the quality of sound beam is excessive, causes the excessive instrument panel that causes of total quality of musical instrument to produce too much resistance in the process of vibration sounding, has weakened the vibrating effect of soundboard; Musical instrument in use, the vibrations of audio frequency run into traditional solid sound Liang Bi can be obstructed and produce refraction effect, thereby produces discordant noise.How to provide a kind of and not only can alleviate sound beam weight, and can make the better sound beam of audio frequency vibrating effect of musical instrument become the urgent demand of musical instrument designing technique personnel.
The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, provide a kind of and not only can alleviate traditional solid sound beam weight and the constant sound beam of structural strength, this musical instrument sound beam can make instrument panel and resonant tank obtain bigger unobstructed vibration area and space, has alleviated the load of panel effectively.
The purpose of this utility model realizes by following scheme: a kind of sound beam of musical instrument, the wooden sound beam main body that comprises strip, described sound beam main body comprises upper side, leading flank, trailing flank and is positioned at the smooth binding face of downside, described sound beam main body is provided with several audio frequency through holes, and described audio frequency through hole connects described leading flank and described trailing flank.
Described sound beam main body is provided with several audio frequency through holes, and the upper side of described sound beam main body is provided with inserting groove, and described inserting groove can be fixing for pegging graft mutually between sound beam and the sound beam.
Advantage of the present utility model is: because sound beam of the present utility model is provided with a plurality of audio frequency through holes, its effect is: 1, alleviated the weight of traditional solid sound beam effectively, strengthened the elasticity of sound fine strain of millet, made instrument panel obtain better vibrating effect; 2, reduce sound beam sides area effectively, and lower to the audio frequency refraction effect in addition, therefore can obtain harmonious tone color, make volume bigger generouser.The structural strength of the utility model sound beam is identical with traditional solid sound beam, owing to the alleviating of weight of sound beam greatly strengthens the elasticity of sound beam, make the instrument panel load reduction, thereby the sound that musical instrument is sent is generouser and fine and smooth.The utility model not only can alleviate sound beam weight, makes all high-qualitys more of the audio frequency vibrating effect of musical instrument and tone color.
Description of drawings
Fig. 1 is the positive perspective view of the sound beam of a kind of musical instrument of the utility model;
Fig. 2 is the back side perspective view of the sound beam of a kind of musical instrument of the utility model;
Wherein: 1. sound beam main body; 2. upper side; 3. leading flank; 4. trailing flank; 5. binding face; 6. audio frequency through hole; 7. inserting groove.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Extremely shown in Figure 2 as Fig. 1, a kind of sound beam of musical instrument, the wooden sound beam main body 1 that comprises strip, described sound beam main body 1 comprises upper side 2, leading flank 3, trailing flank 4 and is positioned at the smooth binding face 5 of downside, described sound beam main body 1 is provided with 6 audio frequency through holes 6, described audio frequency through hole 6 connects described leading flank 3 and described trailing flank 4, and the upper side 2 of described sound beam main body 1 is provided with inserting groove 7.
Should be noted that at last, accompanying drawing and above content are only in order to the explanation the technical solution of the utility model, the simple modification that others skilled in the art and enterprise carry out the technical solution of the utility model as: increase or reduce honeycomb audio frequency hole, change shape, perhaps be equal to or replace, the essence and the scope that all do not break away from technical solutions of the utility model allow to use without authorization the infringement that all is considered as the utility model technology without the inventor.
Claims (2)
1. the sound beam of a musical instrument comprises the wooden sound beam main body of strip, and it is characterized in that: described sound beam main body is provided with several audio frequency through holes.
2. according to the sound beam of the described a kind of musical instrument of claim 1, it is characterized in that: described audio frequency through hole connects described leading flank and described trailing flank.
