Abstract

The utility model relates to a percussion instrument and particularly relates to a drum set with a silencer. The drum set comprises a drum cavity wall, a drum skin and the silencer in a drum cavity. The drum set provided by the utility model is characterized in that horizontal sliding grooves are arranged on the drum cavity wall and are corresponding front and back; vertical grooves, which extend downward, are arranged at the both sides of the sliding grooves; the silencer consists of a pair of semicircular or semi-oval rubber cushions and a pair of supporting rods; the rubber cushions are fixed on the supporting rods; the supporting rods pass through the drum cavity and are horizontally installed in the sliding grooves at the front and back of the drum cavity wall; the both ends of the supporting rods are fixed by nuts; and the upper surfaces of the rubber cushions are tightly adhered to the lower surface of the drum skin. By adjusting the distance between the two rubber cushions, different degrees of silencing effects can be achieved. The drum set provided by the utility model has the advantages that the silencing effect is obvious, the problem of disturbing residents can be solved when a drummer practices the drum, and better hand feel under a silencing state can be achieved so as to not influence the practice effect of the drummer; the silencer does not influence tone quality when the drummer performs the drum normally; and the drum set provided by the utility model is suitable for various drum percussion music.

Description

The frame drum that has exhaust box

Technical field

The utility model relates to a kind of percussion instrument, relates in particular to a kind of frame drum.

Background technology

Frame drum is a kind of Western percussion music of circle, and sound is very big when beaing performance, but student and the drummer this very big sound when carrying out the frame drum exercise will produce the problem that disturbs residents; A lot of for this reason drummers are rubber blanket on the drum head upper berth; Sound has obviously reduced like this, but this can influence in one's hands having an effect, and feels also just flat; Effect to drummer exercise is just made a discount greatly, and the raising of drummer's technical ability is brought certain resistance.Application number is 200820076343.6 Chinese patent, discloses a kind of frame drum of embedded with drum pad capable of adjusting volume, and its drum pad contacts with drum head when exercise.Reach the purpose of noise reduction, its drum pad moves down with drum head and breaks away from when formal performance, but the drum head normal articulation; The drum pad was parallel all the time with drum head when the shortcoming of this device was the drum head normal articulation; Drum pad retaining hinders sound wave and fully resonates in the middle of drum head up and down, influences tonequality.Application number is 200920101590.1 Chinese patent, discloses a kind of embedded moving type muffler apparatus for drum, is made up of drum silencing pad supporting plate and silencing pad; Its quieter is mounted in bulging chamber one side, and it is through regulating embedded with drum pad, make its near and withstand drum head and reach its erasure effect; Shortcoming is: when locating the noise reduction state, the drummer directly hits the drum pad of built-in exhaust box, has a strong impact on feel; Can't realize the sensation of real strike drum face, erasure effect neither be fairly obvious.

Summary of the invention

The problem that the utility model will solve provides a kind of frame drum that has exhaust box, and this frame drum both can noise reduction when the drummer practises, and the feel of hitting drum head is arranged again, the tonequality when also not influencing simultaneously normal performance.

For addressing the above problem; The technical scheme that the utility model adopts is: the frame drum that has exhaust box; Comprise the quieter in bulging chamber wall, drum head and the drum chamber, it is characterized in that: corresponding horizontal concrete chute before and after drum chamber wall is provided with, the both sides of chute are provided with to the cannelure that extends below; Quieter is made up of a pair of semicircle or half elliptic rubber blanket and pair of support rods; Rubber blanket is fixed on the support bar; Support bar passes bulging chamber level and is installed in the chute before and after the bulging chamber wall, and fixed by nut is used at two ends, and the upper surface of rubber blanket is close to the lower surface of drum head.When two rubber blankets are close together between two parties; Tangible sound deadening can be played,, a void area will be abdicated in the middle of the semicircular rubber blanket when behind two side shifting support bars; When this moment, the drum hammering was beaten on the drum head on void area; Not only good muffling effect, and feel is better, does not influence the effect of exercise.When support bar is moved on to the both sides of horizontal concrete chute, just get into cannelure, support bar sinks; Rubber blanket can be away from top drum head; Simultaneously become state vertically downward by horizontality, at this moment the quieter of frame drum can not influence tonequality, can normally perform use.

The further improvement of the utility model, the said support bar part xsect in horizontal concrete chute is following on being to be horizontal line, and the right and left is the flat structure of circular arc line, can prevent that like this support bar from rotating, and influences erasure effect.

A step again of the utility model improves; The shutoff slideway gap that is used for of all overlapping a circle near the inboard of drum chamber wall at the two ends of support bar prevents to rouse the thin slice of ventilating inside and outside the chamber, spring of back cover of thin slice, and the other end of spring withstands on the positive stop lug boss on the support bar (4); The thin slice outside is corresponding with the arc of drum chamber wall; And withstood the inboard that abuts against bulging chamber wall by spring, and can prevent that like this outer chute is ventilated in the drum chamber, influence tonequality.Can certainly adopt the slit of other mode shutoff slideway, reach close effect.

Compared with prior art, the beneficial effect of the utility model is: not only erasure effect is obvious, has eliminated the problem that disturbs residents, and feel is better when the noise reduction state, does not influence the effect of drummer's exercise, and quieter can not influence bulging tonequality when normally performing.The utility model is applicable to various drum type percussion music.

Embodiment

Shown in Fig. 1-4, have the frame drum of exhaust box, comprise the quieter in bulging chamber wall 1, drum head 2 and the drum chamber, corresponding horizontal concrete chute 6 before and after drum chamber wall 1 is provided with, the both sides of horizontal concrete chute 6 are provided with to the cannelure that extends below 5; Quieter is made up of pair of semicircular shaped rubber blanket 3 and pair of support rods 4; Rubber blanket 3 is fixed on the support bar 4; Support bar 4 passes in the chute 6 that bulging chamber level is installed in wall 1 front and back, bulging chamber, and fixed by nut is used at two ends, and the upper surface of rubber blanket 3 is close to the lower surface of drum head 2.The part xsect of support bar 4 in horizontal concrete chute 6 is that upper and lower limit is the flat structure of circular arc line for horizontal line the right and left.The shutoff slideway gap that is used for of all overlapping a circle near the inboard of drum chamber wall 1 at the two ends of support bar 4 prevents to rouse the thin slice of ventilating inside and outside the chamber; Spring of back cover of thin slice; The other end of spring withstands on spacing on the support bar 4; The thin slice outside is corresponding with the arc of drum chamber wall 1, and is withstood the inboard that abuts against bulging chamber wall 1 by spring.

So just can be reached by the size of the determining positions of rubber blanket resonance area and reduce the purpose that shakes in various degree, the vibroshock that 2 semicircle rubber blankets are done merges, and just can reach the purpose of thorough damping and silencing.
