Abstract

The utility model relates to a novel drum which is composed of a drum body and drum leather. The drum leather is sealed and installed on both head faces of the drum body through a drum ring. The novel drum is characterized in that: synthetic glass is heated, stretched and integrated as a whole to form the drum body. The drum body takes the shape of a tube with the wholly sealed circumference. The novel drum of the utility model has simple structure and reasonable design. By breaching the constraint of the process and the structure of the traditional wooden drum, the synthetic glass is firstly adopted to produce the tube-shaped drum body with the wholly sealed circumference. The drum body has the advantages of light weight, high mechanical strength, high transparency, beautiful and unique appearance, simple process, low cost, etc. By adopting the drum body made from the synthetic glass, the drum has better general air tightness, thus having a better effect of resonance and saving wood raw material. The novel drum has the advantages of saving energy, environmental protection and relatively high novelty.

Description

Novel drum

Technical field

The utility model relates to the bulging class in musical instrument field, particularly a kind of novel drum.

Background technology

Drum is a kind of widely used percussion instrument, and its structure is generally by drum head and drum body two parts and constitutes, and adopts the drum circle that drum head and drum body are fixed.Drum head is the sounding body of drum, and the drum body is the resonator of drum, and the leakproofness of resonator will directly influence bulging sympathetic response effect.Existing bulging body is wooden cylindrical shell, carry out reel by the mode that wooden boards is hot-forming, to carry out bonding formation Shell drum body to edge fit again, existing wooden bulging body has following shortcoming: 1. the fabrication and processing forming process of wooden bulging body is comparatively complicated, the bulging body after the moulding and the installed surface flatness of drum head are not enough, cause bulging body and drum head to install and cooperate the back impermeability relatively poor, rouse the impermeability that the body interface also influences drum to a certain extent simultaneously, thus the sympathetic response effect of influence drum; 2. the making of rousing body needs a large amount of high-quality timber, and cost is higher, and long-term large batch of production will inevitably consume great deal of raw materials, and energy-output ratio is bigger, is unfavorable for energy-conserving and environment-protective; 3. the weight of wooden bulging body is big and intensity is lower, long-term use to be easy to generate damage or metaboly, influence is played.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, the novel drum of a kind of employing by the circumferential one closed tube shape drum body of organic glass heating drawing and forming is provided, its have simple in structure, machine-shaping fast, advantage such as regular shape, impermeability be good.

The utility model solves its technical matters and takes following technical scheme to realize:

A kind of novel drum is made of drum body, drum head, and drum head encloses the both ends of the surface that are packaged in bulging body by drum, and it is characterized in that: it is one-body molded that described bulging body adds hot-stretch by organic glass, and it is shaped as the tubular of circumferential one sealing.

And, being fixed with circumferentially uniform wall card in drum body outer wall symmetry, this wall card all is equipped with the drum that the end chucking is connected on the drum circle and colludes.

Advantage of the present utility model and good effect are:

1. the bulging body of this novel drum adopts organic glass to replace traditional timber, form the Shell drum body of circumferential one sealing by the heating stretching mode, its regular shape, the drum lower limb is smooth smooth on one's body, drum body and drum head encapsulation back impermeability effect are preferable, and the unmatchful face that connects makes progress in week, strengthen the impermeability and the intensity of drum body, this kind drum body has better sympathetic response effect, has preferable musical expression.

2. the bulging body of this novel drum processings of can holing, and not breaking, therefore can be the same with traditional bulging body direct wall be fixed is loaded on one's body the drum, installs to rouse by this wall card and colludes, to play fastening drum head and to rouse body, the effect of tensioning drum head.

3. this novel drum can save a large amount of high-quality timber as drum body raw material, significantly reduces expending of the energy, helps energy-conserving and environment-protective; Simultaneously, organic glass is adopted in the making of drum body, is that organic glass is used in the expansion in musical instrument field.

4. the utility model is simple in structure, design science is reasonable, break through body processing of conventional wooden drum and structural limitation, adopting organic glass to make first becomes the Shell drum body of circumferential one sealing, that the drum body has is in light weight, physical strength is high, transparency is high, novelty attractive in appearance, easy to process, low cost and other advantages, adopt the drum of this kind organic glass drum body to have better whole impermeability, thereby has better sympathetic response effect, save wood raw material simultaneously, energy-conserving and environment-protective are the higher novel drums of a kind of novelty.

Fig. 1 is structural representation of the present utility model (partial sectional view).

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described, following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.

This novel drum is made of drum body 1, drum head 2, and drum head is packaged in the both ends of the surface of bulging body by drum circle 3, and its innovative point is: the drum body is by the organic glass heating and stretch one-body moldedly, and it is shaped as the tubular of circumferential one sealing.Because organic glass has the advantage that is easy to process, the mode that adopts heating and stretch can stretch raw material according to the required height of drum body cylindrical shell becomes rule and satisfactory tubular, and the Shell drum of moulding is in the one sealing that makes progress in week, therefore no interface has stronger toughness, physical strength and leakproofness; The last lower limb of Shell drum body is smooth smooth, thus its with drum head install cooperates after, more wooden bulging body has better impermeability, strengthens bulging body sympathetic response effect.The bulging body of organic glass can be holed, and does not break, damages, and therefore can equally with traditional wooden bulging body be fixed with circumferentially uniform wall card 4 in its outer wall symmetry, and the drum that this wall card all is equipped with end chucking connection drum circle colludes 5.

Claims

1. a novel drum is made of drum body, drum head, and drum head encloses the both ends of the surface that are packaged in bulging body by drum, and it is characterized in that: it is one-body molded that described bulging body adds hot-stretch by organic glass, and it is shaped as the tubular of circumferential one sealing.

2. novel drum according to claim 1 is characterized in that: be fixed with circumferentially uniform wall card in drum body outer wall symmetry, this wall card all is equipped with the drum that the end chucking is connected on the drum circle and colludes.
