Abstract

The invention discloses a panel for an acoustic guitar drum body and aims at overcoming the defects that in the existing acoustic guitar drum body,because a sound beam is complex in structure and configuration, the manufacture is troublesome, the manufacturing efficiency is not high, the tone quality is irregular, a good piano is difficult to obtain, and an outer end head of a cross sound beam isclamped on the surrounding edge in the panel, the panel is non-uniform in vibration and is poor in tone color, and the like. The technical scheme provided by the invention has key points that the panel is a wooden main board body attached to the top of the surrounding edge of the acoustic guitar drum body; and sound holes are formed in the wooden main board body. The panel is characterized in that a wooden secondary board body of which the circumferential shape is approximate to the circumferential shape of the main board body and of which the peripheral size is smaller than that of the main board body is stuck on the inner side of the main board body, and the secondary board body is covered to the peripheries of the sound holes of the main board body; a convex ring of which the section is of a peak shape is attached to the peripheries of the sound holes of the auxiliary board body; and when the main board body is correspondingly connected with the top of the surrounding edge, a certain distance is reserved between the periphery of the secondary board body and a corresponding inner lining strip on the surrounding edge of the secondary board body.

Description

A kind of panel of wooden guitar drum body

Technical field

The present invention relates to a kind of parts of musical instrument, specifically a kind of panel of wooden guitar drum body.

Background technology

The wood guitar is to send the guitar primary sound by the drum body the sound Amplitude amplification of string vibration and from drum sound hole with it.The bulging body structure of wood guitar is made of panel, base plate, surrounding edge, wholesale wood, sound beam and interior lead-in, wherein the corresponding connection of panel surrounding edge top, base plate correspondence connect the surrounding edge bottom and consist of the outer wall construction that rouses the body casing, wholesale wood is arranged at the position that the qin handle is installed in the bulging body, the sound beam is arranged at the place, the back side of panel and base plate, interior lead-in is located on the surrounding edge in the bulging body junction with panel, base plate, and sound hole is located on the panel.

The panel of the wooden guitar drum body that generally uses at present, its lateral surface is smooth plate face, the sound hole upside of its medial surface (namely close qin is a side) locates to be pasted with the upper support crossbeam of being used as back support, be pasted with control overtone sympathetic response amount on the panel medial surface of upper support crossbeam below, the sound beam of the effect such as the form of tenuto or the tone color variable quantity when different volume, the sound beam has generally comprised cross sound beam, Da Yinliang, little sound beam etc.Because the structure of sound beam and configuration are very exquisite and complicated, to the manufacturing trouble that arrived, cause making efficient not high, the tonequality quality is uneven, so that good qin difficulty is asked; In addition, the external end head of cross sound beam must fix on the breach at surrounding edge top in the manufacturing, tends to cause panel vibration inhomogeneous, causes tone color not good.

Summary of the invention

For the panel that overcomes existing similar wooden guitar drum body exists sound girder construction and configuration complexity, make trouble, make efficient not high, tonequality is uneven, good qin difficulty is asked, and the external end head of cross sound beam fixes on the breach of surrounding edge, can cause the defectives such as the inhomogeneous and tone color of panel vibration is not good, the invention provides a kind of panel of improved wooden guitar drum body, can overcome the defective of prior art.

The technical solution adopted for the present invention to solve the technical problems is: a kind of panel of wooden guitar drum body, that a slice is used to stick on the wooden mainboard body that wooden guitar rouses the surrounding edge top of body, which is provided with sound hole, it is characterized in that: be pasted with on the mainboard body medial surface that a slice peripheral shape is similar to mainboard body peripheral shape and peripheral size less than the wooden subplate body of mainboard body, and the subplate body is covered to around the sound hole of mainboard body, sound hole periphery place on the subplate body is pasted with the flange collar in shape cross section, a mountain peak, when the mainboard body links together with the surrounding edge top is corresponding, be separated with certain distance between between the corresponding interior lead-in on subplate body periphery and the surrounding edge.

Between the corresponding interior lead-in on the subplate body of technique scheme periphery and the surrounding edge apart from being taken at 5～60 millimeters.

The thickness of the subplate body of technique scheme can be taken at 2～4 millimeters.

Lead-in refers to be in the interior lead-in of mainboard body and corresponding junction, surrounding edge top in technique scheme corresponding.

Upside (namely close qin is a side) in flange collar on the mainboard body medial surface of technique scheme is located to be pasted with the upper support crossbeam that the enhancing back support is used, with bending resistance, the non-deformability on reinforced panel top.

On the subplate body of technique scheme between the downside and Qin Qiao place correspondence position (the qin bridge is mounted on the external side of mainboard of this position) of wooden flange collar, tilting support cant beam can be set, so that bending resistance, the non-deformability at Qin Qiao position to be installed on the reinforced panel.

The wooden guitar of technique scheme can be unfilled corner wood guitar, also can be full-shape wood guitar.

A slice mainboard body of technique scheme can be to be made of the whole piece plate body, also can be to be that a slice consists of by two and half plates docking; Mainboard body or subplate body can be laminas, also can be the plywood more than two layers.

The shape cross section, so-called mountain peak of technique scheme refers to that the cross section is convex shape high in the middle and low on both ends, and its protruding gradient or domatic curve shape can be set according to actual needs.

The flange collar of technique scheme generally can adopt wood materials, also can adopt plastic material.

The invention has the beneficial effects as follows: peripheral size is less than the subplate body of mainboard body owing to adopting a peripheral shape to be similar to mainboard body peripheral shape, stick on the mainboard body medial surface and be covered to around the sound hole, sound hole periphery place on the subplate body is pasted with the flange collar in shape cross section, a mountain peak, with the sound beam that arranges through complexity on the panel of this alternative log guitar, facts have proved, the present invention not only can reach sound beam control overtone sympathetic response amount, the effect such as the form of tenuto or the tone color variable quantity when different volume and due tamber effect, and can have better tone color and larger volume, thereby it is simple to reach panel construction, easily manufactured, manufacturing efficient is high, and can not occur having an obvious uneven problem of tonequality between the wooden guitar, qin is easily asked; Owing to being separated with certain distance between between the corresponding interior lead-in on subplate body periphery and the surrounding edge, so sound beam breach need not be opened in the surrounding edge top, there is not the sound beam outer end headstock to be placed on the surrounding edge yet, thereby the external end head that has overcome log guitar cross sound beam fixes on the surrounding edge breach, wooden guitar causes the inhomogeneous and not good problem of tone color of panel vibration, so that can reach its best tone color.

The invention will be further described below in conjunction with drawings and Examples.
