Abstract
The utility model relates to a two chinese fiddle section of thick bamboos, which comprises a pane, the covering, connecting pin and drag the pad, wherein the panel is totally six, and the first the connection constitutes inclosed regular hexagon tube -shape cavity in proper order, the cavity both ends are by the covering cladding, the tooth is connected to the equipartition on the connection side between the panel, establish the locating hole on the connection tooth in addition, connect through connecting the tooth meshing between the panel, and the connecting pin locates to be connected the positioning hole connector of tooth in addition with dual board contact surface, lie in four at least acoustic windows of equipartition on the panel of below in the panel, and its surface is connected with dragging the pad through adjusting bolt in addition, drag fill up with the panel of below between at least 4 pieces that pronounce of equipartition in addition, this novel connection stability is good, high structural strength, can the intermural emergence resonance phenomenon of an effectual reduction resonance musical instrument section of thick bamboo, can ensure effectively on the one hand that the two -stringed bowed instrument audio is stable, on the other hand still and help and improve the life of a musical instrument section of thick bamboo, herein simultaneously, in addition can the adjustment such as enlarge to two -stringed bowed instrument audio and tone quality, improve the performance effect of two -stringed bowed instrument.
Description
Technical field
The utility model relates to a kind of two-stringed piano drum, belongs to instrument devices technical field.
Background technology
Formed by bonding boa skin of then coveing with at used two-stringed piano drum general polylith panel at present, in use find, due to the contraction of big skin self, and easily cause qin cylinder during Erhu playing and produce resonance effect with string, thus cause qin cylinder panel easily to ftracture, have a strong impact on the acoustical quality of urheen, and reduce the serviceable life of urheen, in order to overcome this problem, also have at present and on qin cylinder, add tag strengthen, but aglet is bad with qin cylinder globality on the one hand, affect result of use, can not effectively protect whole qin cylinder on the other hand, therefore result of use is poor, therefore need a kind of novel two-stringed piano drum structure of exploitation to overcome the deficiency of current use.
Utility model content
For the deficiency that prior art exists, the utility model provides a kind of two-stringed piano drum, and this new structure is simple, and connective stability is good, structural strength is large, and effectively can reduce between resonance qin barrel resonance effect occurs, effectively can guarantee that urheen audio is stablized on the one hand, also help and the serviceable life of improving qin cylinder on the other hand, simultaneously, separately according to use needs, the adjustment such as amplification can be carried out to urheen audio and tonequality, improve the playing effect of urheen.
To achieve these goals, the utility model realizes by the following technical solutions:
A kind of two-stringed piano drum, comprise panel, covering, connecting pin and drag pad, wherein panel totally six, and head and the tail connect and compose airtight regular hexagon tubular cavity successively, cavity two ends are coated by covering, uniform connection tooth on connection side between panel, connect on tooth and separately establish pilot hole, be connected with a joggle by connecting tooth between panel, and the another pilot hole being connected tooth with two panels surface of contact place of connecting pin connects, uniform at least four acoustic windows on the panel being positioned at bottom in panel, and its outside surface is separately connected with dragging to pad by adjusting bolt, pad xsect is dragged to be isosceles trapezoid, it is highly not more than 1/2 of the tubular cavity diameter that panel is formed, pad distance panel distance is dragged to be 0.5-3 centimetres, another uniform at least 4 pieces of sheets that pronounce between the panel dragging pad and bottom.
Further, all separately cementing agent is established between described plate contact face and between pilot hole and connecting pin surface of contact.
Further, the described mat thickness that drags is at least 3 times of plate thickness.
This new structure is simple, connective stability is good, structural strength is large, and effectively can reduce between resonance qin barrel resonance effect occurs, effectively can guarantee that urheen audio is stablized on the one hand, also help and the serviceable life of improving qin cylinder on the other hand, simultaneously, separately according to use needs, the adjustment such as amplification can be carried out to urheen audio and tonequality, improve the playing effect of urheen.
Accompanying drawing explanation
The utility model is described in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is this new structure schematic diagram;
Fig. 2 is panel construction schematic diagram.
Embodiment
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.
A kind of two-stringed piano drum as described in Fig. 1 and 2, comprise panel 1, covering 2, connecting pin 3 and drag pad 4, wherein panel 1 totally six, and head and the tail connect and compose airtight regular hexagon tubular cavity successively, cavity two ends are coated by covering 2, uniform connection tooth 5 on the connection side between panel 1, connect on tooth 5 and separately establish pilot hole 6, be connected with a joggle by connecting tooth 5 between panel 1, and the another pilot hole 6 being connected tooth 5 with two panels 1 surface of contact place of connecting pin 3 connects.
In the present embodiment, uniform at least four acoustic windows 7 on the panel 1 being positioned at bottom in described panel 1, and its outside surface is separately connected with dragging pad 4 by adjusting bolt 8, pad 4 xsect is dragged to be isosceles trapezoid, it is highly not more than 1/2 of the tubular cavity diameter that panel 1 is formed, drag pad 4 to be 0.5-3 centimetres apart from panel 1 distance, to drag between the panel 1 of pad 4 and bottom separately uniform at least 4 pieces of sheets 9 that pronounce.
In the present embodiment, between described panel 1 surface of contact and between pilot hole 6 and connecting pin 3 surface of contact, all separately establish cementing agent.
In the present embodiment, described pad 4 thickness that drags is at least 3 times of panel 1 thickness.
This new structure is simple, connective stability is good, structural strength is large, and effectively can reduce between resonance qin barrel resonance effect occurs, effectively can guarantee that urheen audio is stablized on the one hand, also help and the serviceable life of improving qin cylinder on the other hand, simultaneously, separately according to use needs, the adjustment such as amplification can be carried out to urheen audio and tonequality, improve the playing effect of urheen.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
