JP3205399U - Vibration membrane pressurization mechanism for plucked string instruments with taiko drums such as banjo or percussion instruments such as small drums - Google Patents

Abstract

A vibrating membrane pressurizing mechanism for a plucked string instrument having a drum drum such as a banjo or a percussion instrument such as a small drum is provided. SOLUTION: A vibrating membrane fixing ring 4 is provided as a means for fixing a diaphragm outer peripheral edge to a plucked instrument body having a drum drum such as a banjo or a percussion instrument body such as a small drum. A diaphragm pressurizing mechanism that causes the pressurizing mechanism to apply tension to the diaphragm 2 provided inside the drum drum 1 by holding the diaphragm peripheral edge 8 from the bottom of the structure by the diaphragm fixing frame bolt 7. Therefore, the present invention provides a drum drum vibrating membrane pressurizing mechanism that can significantly reduce the number of metal parts and make a lighter musical instrument. In addition, it offers improved design flexibility. [Selection] Figure 1

Description

  The present invention is a pressure mechanism provided inside a body and a diaphragm for a plucked string instrument such as a banjo or a percussion instrument such as a small drum. This is related to a pressurizing structure that pushes up the bolt by screwing it up and applies a playable tension to the diaphragm.

  In a plucked string instrument such as a banjo or a percussion instrument such as a small drum, which has been widely used in the past, the diaphragm for expanding the sound of the string is pushed down by the external pressure ring, and the frame of the diaphragm is pushed down. A method of applying tension to the diaphragm fixed by the body is adopted, and a mechanism for applying tension to the diaphragm with 10 to 24 hooked screws to apply tension to the diaphragm is as follows: It was a factor that made heavy use of metal parts, increased the overall weight, put a burden on the performer, and made the performance itself difficult. Further, in order to uniformly install the fastening metal fittings outside the cylindrical body, the external shape is uniform.

The problem to be solved is to reduce the weight of a plucked string instrument such as a banjo or a percussion instrument such as a small drum, and to make it easier to play a plucked string instrument such as a banjo or a percussion instrument such as a small drum. Is one of the issues. Further, since the fastening metal fittings are uniformly installed outside the cylindrical body, the external shape becomes uniform, and it is difficult to improve the design.

Vibration attached to the body of a plucked string instrument such as a banjo, or a plucked instrument such as a small drum or a percussion instrument such as a small drum The main feature is to pressurize the diaphragm fixed by the membrane fixing ring until the tension required for the performance is maintained by pushing the pressure ring provided inside the fuselage evenly from the bottom to the top with a plurality of bolts. Means.

In the present invention, it is possible to greatly reduce the metal parts of a drum drum such as a banjo that uses a lot of metal parts or the percussion instrument such as a small drum, and a plucked string instrument that has a drum drum such as a banjo that is easier to hold lightly. Or, providing a percussion instrument such as a small drum is one of the effects of the idea, and giving the degree of freedom to the external design is two.

It is sectional drawing of a percussion instrument vibration membrane pressurization mechanism, such as a plucked string instrument with a drum drum, such as a banjo, or a small drum. It is a perspective view of the internal structure of a plucked string instrument having a drum drum such as a banjo or a percussion instrument vibrating membrane pressurizing mechanism such as a small drum.

Hereinafter, the form for implementing this invention is demonstrated.
The diaphragm fixing ring (4) disposed on the drum drum (1) is fixed with the bolt (7) for the diaphragm fixing frame from the bottom of the drum drum (1) structure, and the diaphragm outer peripheral edge (8) is fixed. Hold down.
A pressure ring (3) is provided below the vibrating membrane (2).
A plurality of pressure ring bolts (6) installed on the pressure ring bolt holding convex portion (5) provided at the lower portion of the pressure ring (2) are screwed from the pressure ring bolt holding convex portion (5). Raise the pressure ring (2). The diaphragm (2) fixed by the diaphragm fixing frame (4) is pressurized by the pressurizing ring (2), and a playable tension is applied to the diaphragm (2).
In addition, by installing this diaphragm pressurization structure inside a plucked instrument with a drum drum such as a banjo or a percussion instrument body (1) such as a small drum, it is possible to give freedom to the design of the external structure. It makes it possible to produce plucked string instruments such as banjos with various appearances and percussion instruments such as small drums.
