Description

A kind of modified form drum

Technical field

This utility model drum is related to a kind of musical instrument and dancing stage property, and in particular to a kind of modified form drum.

Background technology

Minorities in Yunnan rich culture is colorful, good at singing and dancing；This nationality is expressed by musical instrument and dancing to life Understand and fine pursuit, Minorities in Yunnan musical instrument kind about more than 100, from the Chinese bronze chime bells and copper of the Warring States Period Yunnan people creation Drum, Wa people's wooden drum finally and drum on a pedestal of the Dai nationality etc., it is seen that as percussion music be each nationality hobby simultaneously.

But traditional bulging acoustic construction is not reasonable, drum chamber inwall, resonator, louver and whole drum profile do not have Good sound entirety sympathetic response is formed, is caused traditional drum to impact and is sent the single sound of tone color, be hardly formed tone color rich Rich music, affects the use feeling of music-lover.

Utility model content

The purpose of this utility model drum is to provide that a kind of tone color is abundant, profile svelteness, assembles the peculiar people in Yunnan The representative drum culture of race, with reference to modern society's fashion, fashion elements, and can meet various modes and beat and play the modified form of requirement and rouse.

The purpose of this utility model drum is achieved in that including drum body the bulging body includes arranging from top to bottom Drum head, drum chamber, spur, resonator, leakage sound inner chamber, playback aperture and playback mouth, the drum head are set from top to bottom in drum chamber It is drum surface accent with drum chamber junction, drum surface chamber mouth inner and outer side is connected with drum head arc transition, the resonator is vertical to be cut Face is spherical hopper type, and the leakage sound inner chamber is up big and down small horn-like, for realizing the circular arc of resonator and playback aperture Transition connects, playback aperture bottom arc transition connection playback mouth, the playback mouth be it is up-small and down-big horn-like, it is described Drum chamber longitudinal section is in integrally goblet shape.

Drum surface chamber mouth inner and outer side and drum head are bordered on partial arc mistake by this utility model drum on the basis of original drum on a pedestal Cross, effectively reduce abrasion of the drum surface accent to drum head, there is protective effect to drum head, and improve the comfortable of player's percussion Degree；It is spherical hopper type by the traditional conical hopper type improvement of resonator；The space for making resonator increases；Subsphaeroidal resonator energy Different resonating effects are given play to；Playback aperture is together flaring leakage sound inner chamber between tymapanum, promotes resonator to playback The sound conduction in aperture；The setting of drop-down circle platform causes drum chamber integrally more to coordinate, and drop-down circle is moved up, and has Enough support forces support the pulling force of drop-down circle；Playback mouth is horn-like, can promote the conduction of sound and the expansion of volume.

This utility model drum on the basis of original drum on a pedestal, from resonator, leakage sound inner chamber, playback aperture, playback mouth with And whole drum profile carries out improvement design, the cydariform after improvement can impact out various differences into the entirety sympathetic response of good sound The sound, play with changeable rhythm so as to defining a kind of Novel drum and can beating, changeable pitch can be sent, can have loud and clear sound Ring the ethnic groups drum of effect；Appreciation and succession protection to improving national arts culture is significant.

Specific embodiment

This utility model drum is further described below in conjunction with the accompanying drawings, but must not by any way to this utility model Drum is any limitation as, and any change or improvement made is roused based on this utility model, belongs to the protection domain of this utility model drum.

As shown in Figure 1 and 2, this utility model includes drum body, and the bulging body includes drum head 8, the drum for arranging from top to bottom Resonator 1, leakage sound inner chamber 2, playback aperture 3 and playback mouth 4, the drum head 8 are set from top to bottom in chamber, spur 6, the drum chamber It is that outside is connected with the arc transition of drum head 8 in drum surface accent 7, the drum surface accent 7 with drum chamber junction, the resonator 1 Longitudinal section is spherical hopper type, and the leakage sound inner chamber 2 is up big and down small horn-like, for realizing resonator 1 and playback aperture 3 Arc transition connection, the bottom arc transition connection playback mouth 4 of the playback aperture 3, the playback mouth 4 is up-small and down-big loudspeaker Shape, the drum chamber longitudinal section is in integrally goblet shape.

The vertical height ratio of the resonator 1, leakage sound inner chamber 2, playback aperture 3 and playback mouth 4 is 228.83:55.31: 125.42:189.9。

The vertical height of the resonator 1 is 228.83mm, and the internal diameter of the resonator 1 is progressively reduced to by 220mm 106.35mm, the vertical height of the leakage sound inner chamber 2 is 55.31mm, and the internal diameter of the leakage sound inner chamber 2 is reduced to by 106.35mm 64.47mm, the vertical height in the playback aperture 3 is 125.42mm, and the internal diameter in the playback aperture 3 is reduced to by 64.47mm 60mm, the vertical height of the playback mouth 4 is 189.9mm, and the internal diameter of the playback mouth 4 is expanded to 185.03mm by 60mm.

The outer surface of leakage sound inner chamber 2 arranges the drop-down circle platform 5 of a circle.

The spur 6 is as feet or train of dress shape.

The weight of the bulging body is 3.5 ~ 5.6kg.

Operation principle of the present utility model and the course of work are as follows：

Drum surface accent and drum surface are bordered on partial arc transition, energy by this utility model drum on the basis of original drum on a pedestal Abrasion of the drum surface accent to drum head is effectively reduced, there is protective effect to drum head, and improve the comfortable of music-lover's percussion Degree；The traditional conical hopper type of resonator is changed to into spherical hopper type；The space for making resonator increases；Subsphaeroidal resonator can be sent out Shoot different resonating effects；Playback aperture is together flaring leakage sound inner chamber between tymapanum, promotes resonator to louver The sound conduction in footpath；The setting of drop-down circle platform causes drum chamber integrally more to coordinate, and drop-down circle is moved up, and has foot Enough support forces support the pulling force of drop-down circle；Playback mouth is horn-like, can promote sound conduction and expand volume, the weight of whole drum Amount distribution meets ergonomics.

This utility model drum on the basis of original drum on a pedestal, from resonator, leakage sound inner chamber, playback aperture, playback mouth with And whole drum profile carries out improvement design, the cydariform after improvement into the entirety sympathetic response of good sound, can impact send it is various not With the sound, can beat and play changeable rhythm so as to defining a kind of Novel drum and having, changeable pitch can be sent, can have loud and clear Acoustic ethnic groups drum；Appreciation and succession protection to improving national arts culture is significant.
