Abstract

A drum practice pad having a snare wire adjustment function comprises an elastic member, a striking pad, a base plate, and a snare wire adjustment device. The elastic member is fixed above the base plate. A resonance cavity is disposed below the base plate. The snare wire adjustment device is disposed in the resonance cavity. The snare wire adjustment device comprises multiple steel balls, a T-shaped adjustment rod, an adjustment seat, an adjustment knob, and a spring. The steel balls are placed in the resonance cavity. The resonance cavity is sealed via a cover plate. A horizontal rod at an end portion of the T-shaped adjustment rod isolates the steel balls from an inner wall on one side of the rectangular resonance cavity. A vertical rod of the T-shaped adjustment rod is placed in a slot communicating with the resonance cavity. The spring is sleeved on and fixed to a middle portion of the vertical rod, and a tail portion of the vertical rod is connected to the adjustment knob. The T-shaped adjustment rod is fixedly connected to the base plate via the adjustment seat in a detachable manner. In the present application, a snare wire is adjusted to simulate the actual sound of a drum, such that a beginner practicing on a drum practice pad can still experience the actual sound of a drum without disturbing others, so as to ensure that practicing does not feel monotonous and to accelerate the learning process.

Description

Dumb drum with sand belt adjustment function

Technical field

The present application relates to the field of instrument-assisted teaching, and in particular to a dumb drum with a sand-belt adjustment function.

Background technique

At present, there are many types of dumb drums on the domestic market, but the functions are limited to the changes in the practice feel, hitting speed, and coordination of the limbs. The sound of a real drum, which will affect the practitioner's feeling during the training process. The snare sound that the snare drum can emit comes from a sand belt installed under the snare drum. The sand tape is composed of multiple steel wires arranged in parallel with each other and can resonate with the vibration of the drum skin. This has played a role in enhancing the performance effect, but currently there is no sand belt structure provided on the dumb drum and adjustable.

Overview

The technical problem to be solved by the present application is to provide a dumb drum with a sand belt adjustment function. By setting an adjustable sand belt structure on the dumb drum, a drummer can simulate sound effects similar to a real drum during practice, and increase practice. Real feeling.

In order to solve the above technical problems, the present application is implemented as follows: A dumb drum with a sand belt adjustment function described in this application includes an elastic body, a striking edge, a bottom plate and a sand belt adjustment device; the elastic body is fixed at Above the bottom plate; the striking edge is fixed above the bottom plate, and the striking edge surrounds the elastic body and protrudes from the surface of the elastic body; a resonance cavity is arranged below the bottom plate, and a sand belt adjusting device is arranged in the resonance cavity; The device includes a plurality of steel balls, a T-shaped adjusting rod, an adjusting base, an adjusting knob and a spring. The steel balls are placed in a resonance cavity, and the resonance cavity is sealed by a cover plate. The end crossbar of the T-shaped adjusting rod connects the steel ball with the rectangular resonance cavity. The inner wall of one side is isolated. The vertical rod of the T-shaped adjustment rod is placed in a card slot communicating with the resonance cavity. The middle of the vertical rod is sleeved and fixed with a spring. The tail is connected with the adjustment knob. Fixed connection.

Positive effects of this application: The dumb drum with sand belt adjustment function described in this application has a sound level between real and silent dumb drums, which can not only practice the feel and hitting speed, but also adjust the sand belt and simulate The sound effects of real drums allow beginners to not disturb the people and experience the sound effects of real drums in the practice of dumb drums. The practice is not boring and speeds up the learning process.

detailed description

As shown in FIG. 1 to FIG. 4, a dumb drum with a sand belt adjustment function described in this application includes an elastic body 2, a striking edge 1, a bottom plate 3, and a sand belt adjustment device 4; the elastic body 2 is fixed on the bottom plate. 3; the striking edge strip 1 is fixed above the bottom plate 3, the striking edge strip 1 surrounds the elastic body 2 and protrudes from the surface of the elastic body 2; a resonance cavity 11 is disposed below the bottom plate 3, and a sand belt adjusting device 4 is disposed on the resonance The cavity 11; the sand-belt adjusting device 4 includes a plurality of steel balls 6, a T-shaped adjusting rod 7, an adjusting seat 9, an adjusting knob 10, and a spring 8, the steel balls 6 are placed in the resonance chamber 11, and the resonance chamber 11 passes through a cover plate 5 seals, the end crossbar of the T-shaped adjustment rod 7 isolates the steel ball 6 from the inner wall of one side of the rectangular resonance cavity 11, and the vertical rod of the T-shaped adjustment rod 7 is placed in the card slot 12 communicating with the resonance cavity 11. A spring 8 is sleeved and fixed in the middle of the rod, an adjustment knob 10 is connected to the tail, and a T-shaped adjustment rod 7 forms a detachable and fixed connection with the bottom plate 3 through the adjustment seat 9.

The dumb drum with sand-belt adjustment function described in the present application adjusts the tightness of the steel ball 6 in the rectangular resonance cavity 11 by rotating the adjustment knob 10 to move the T-shaped adjustment rod 7 forward or backward, thereby changing the resonance The size of the cavity 11 realizes the looseness or compactness of the sound density emitted by the sand belt structure, and achieves the pronunciation effect of simulating a real drum. When the T-shaped adjustment lever 7 moves backward, the steel ball 6 becomes loose, and the resonance chamber 11 becomes larger. When the beginner hits the elastic body 2 or the side strip 1, the sound density of the sand belt structure is loose; when T When the shape-adjusting lever 7 is moved forward, the T-shaped adjustment lever 7 gradually presses the steel ball 6 tightly, the steel ball 6 becomes tight, and the resonance chamber 11 is squeezed to become smaller. When beginners hit the elastomer 2 or the side strip 1, the sand The density of the sound emitted by the belt structure becomes compact; a spring 8 is provided in the middle of the T-shaped adjustment lever 7, which can reset the T-shaped adjustment lever 7.

What has been described above is only a schematic illustration of some functional and structural principles of a dumb drum with a belt adjustment function related to the present application. Since it is easy for those skilled in the same technical field to make several modifications on this basis, therefore This specification is not intended to limit a dumb drum with a belt adjustment function described in this application to the specific mechanism and scope of application shown or described. Therefore, any corresponding modifications and equivalents that may be used belong to this specification. The scope of patent protection.
