Description

Gong

Technical Field

The utility model belongs to the technical field of the musical instrument and specifically relates to a gong.

Background

The gong is a metal percussion instrument, generally formed by forging bronze, and has a simple structure, the gong body is a circular arc surface, the periphery of the gong body is fixed by a frame of the gong body, and a player uses a wooden hammer to knock the central part of the front side of the gong body to generate vibration and pronounce.

The size of the gong body has various specifications, the small gong body is lifted by a left hand when being played, and the gong is hammered by a right hand holding wood; the large gong should be hung on the gong frame for playing. It belongs to a metal body musical instrument and has no fixed pitch. Its sound is deep, full and strong, and its lingering sound is long-lasting. Generally, gong is used to represent a stressful atmosphere and a discouraging sign, with a very unique artistic effect.

The traditional gong has a slightly convex central part called as umbilicus, light or hall, which is the main part of pronunciation, the size and thickness of the umbilicus and the area ratio of the gong determine the tone height, and the central part is flat without umbilicus or protrudes into a semi-circle sphere, which all constitute the main characteristics of the gong. The gong surface is called between the gong navel and the gong edge, and two gong holes are drilled on one side of the gong edge so as to thread a gong rope and be convenient for carrying or hanging a gong frame.

Along with the environment and the requirement of current use gong constantly change, when the gong of general structure was used under many occasions, there was following not enough:

1. The sound is divergent. Because the gong navel part in the center of the existing gong is generally convex or flat without a navel, the sound generated during knocking is dispersed and cannot be concentrated.

2. A single sound tone cannot be emitted. Because the gong navel part in the center of the existing gong is generally convex or flat and has no navel, the sound emitted by the knocking sound is deep and loud, and the single tone with stable sound cannot be emitted.

SUMMERY OF THE UTILITY MODEL

In order to solve the above-mentioned technical problem who exists among the background art, the utility model provides a gong has the sound and concentrates, can send the advantage of single sound tone.

The technical solution of the utility model is that: the utility model relates to a gong, including the circular gong body, gong limit, the gong limit sets up in the external side of circular gong body, and gong body central authorities are the gong navel, are the gong face between gong navel and the gong limit, and its special character lies in: the gong navel is circular recess.

The ratio of the excircle radius of the circular groove to the radius of the circular gong body is 1:5 or 1: 4.

The vertical section of the circular groove is an isosceles trapezoid with a wide upper part and a narrow lower part.

The distance from the top edge to the bottom edge of the isosceles trapezoid is 5-20 mm.

The included angle alpha between the bottom edge of the isosceles trapezoid and the side edge is 120-160 degrees.

The distance from the top edge to the bottom edge of the isosceles trapezoid is 10 mm.

The included angle alpha between the bottom edge of the isosceles trapezoid and the side edge is 135 degrees.

The gong surface is a cambered surface.

The utility model has the advantages of it is following:

1. The sound is concentrated. The utility model discloses change the structure of gong navel part of the central authorities of gong of current structure into circular recess by protruding or flat no navel, decide the sound point just in circular recess, its characteristics are same weight, and only beat with the cold hammer and will transfer the tone to circular recess, and when taking the wooden hammer to strike the gong, the sound of sending is concentrated, can not disperse, simultaneously the utility model discloses an experimental and debugging, the area of discovery circular recess excircle is less, and sound is concentrated more easily, and the volume also reduces thereupon, therefore the circular recess excircle radius is 1:5 or 1 with the ratio of circular gong body radius: 4, the pronunciation effect is good.

2. A single tone may be emitted. The utility model discloses the protruding or flat no navel of structure of gong navel part with the central authorities of current structure gong changes circular recess into, when taking the mallet to strike the gong navel, can send single tone.

3. the tone is adjustable. The utility model discloses a pitch point is just in circular recess, and its characteristics are same weight, just beat will transfer the tone to circular recess with the cold hammer, and the tone can beat down selected required tone at the cold hammer, if: A. b, C, D, E, F, G, and simultaneously the utility model discloses an experiment and debugging find that the perpendicular sectional area of circular recess is when the wide isosceles trapezoid of narrow down, and sound effect is best, the utility model discloses can also realize the adjustment of tone through the angle of adjusting isosceles trapezoid's height and isosceles trapezoid base and side.

Detailed Description

Referring to fig. 1 and 2, the utility model discloses a specific embodiment's structure includes the circular gong body 2, gong limit 5, and gong limit 5 sets up in the 2 outsides of the circular gong body, and 2 central authorities of the gong body are gong navel 1, are gong face 3 between gong navel 1 and the gong limit 5, and the shape of gong navel 1 is circular recess, and wherein the ratio of 4 radiuses of circular recess excircle and 2 radiuses of the circular gong body is 1:5 or 1: 4, the pronunciation effect is good. The vertical section of the circular groove is an isosceles trapezoid with a wide upper part and a narrow lower part, the distance from the top edge to the bottom edge of the circular groove is 5-20 mm, preferably 10mm, and the included angle alpha between the bottom edge and the side edge of the isosceles trapezoid is 120-160 degrees, preferably 135 degrees. The gong surface 3 is a cambered surface.
