Abstract

The utility model discloses a piano keyboard regulator which slightly presents an oblong block. One side edge of the oblong is inward concave to form a groove of which the depth is equal to the standard depth of black key; another side edge is outward convex to form a lug boss of which the height is equal to the standard depth of white keys; a third side edge is outward convex to slightly form an n-shaped frame, wherein the height of an inner frame of the n-shaped frame is equal to the standard height of the black keys, and the height of an outer frame of the n-shaped frame is equal to the standard height of the white keys; a fourth side edge presents a flat and straight shape. The utility model has simple structure, integrates various functions of measurement and regulation, and is convenient to measure and regulate piano keyboards.

Description

The fingerboard calibrating device

Technical field

The utility model relates to a kind of fingerboard calibrating device.

Background technology

Usually, fingerboard when calibration be to adopt rule to measure the height and the degree of depth of black, white keyboard, and the concordant degree of white key need be measured by other instruments, and measuring operation is very inconvenient, and the calibration operation that causes keyboard is trouble very also.

The utility model content

The purpose of this utility model is to provide a kind of fingerboard calibrating device, with measurement and the calibration that makes things convenient for fingerboard.

For achieving the above object, solution of the present utility model is:

The fingerboard calibrating device, the bulk that slightly is rectangle, a rectangular side caves inward and forms a groove, the degree of depth of this groove equals the standard depth of black key, and another side outwards protrudes and forms a boss, and the height of this boss equals the standard depth of Bai Jian, the 3rd side outwards protrudes and slightly forms " Jiong " shape frame, the inside casing height of " Jiong " shape frame equals the calibrated altitude of black key, and the housing height of " Jiong " shape frame equals the calibrated altitude of Bai Jian, and four side is flat.

After adopting said structure, the utility model is simple in structure, when being used for the fingerboard calibration, directly with the inside casing of " Jiong " shape frame on black key, can measure the height of black key; On black key and toward pressing down, can measure the degree of depth of black key with groove; The housing of " Jiong " shape frame is leaned against Bai Jianshang, can measure the height of Bai Jian; Pin white key and, can measure the degree of depth of Bai Jian with boss toward pressing down; The side of flat across on several white keys, can be recorded the concordant degree of Bai Jian; The utility model integrates multiple measurement, calibration function, and all measuring operation easily and fast, accurately greatly facilitate the calibration of fingerboard.

Embodiment

See also shown in Figure 1, the fingerboard calibrating device that the utility model discloses, the bulk that slightly is rectangle, a rectangular side caves inward and forms a groove 1, the degree of depth of this groove 1 equals the standard depth of black key, another side outwards protrudes and forms a boss 2, the height of this boss 2 equals the standard depth of Bai Jian, the 3rd side outwards protrudes and slightly forms " Jiong " shape frame 3, the inside casing 31 of " Jiong " shape frame 3 highly equals the calibrated altitude of black key, the housing 32 of " Jiong " shape frame 1 highly equals the calibrated altitude of Bai Jian, and four side is flat.

The utility model is used for fingerboard when calibration, as shown in Figure 2, directly with the inside casing 31 of " Jiong " shape frame 3 on black key, can measure the height of black key.As shown in Figure 3, on black key and toward pressing down, can measure the degree of depth of black key with groove 1.As shown in Figure 4, the housing 32 of " Jiong " shape frame 3 is leaned against Bai Jianshang, can measure the height of Bai Jian.As shown in Figure 5, pin white key and, can measure the degree of depth of Bai Jian with boss 2 toward pressing down.As shown in Figure 6, the side of flat across on several white keys, can be recorded the concordant degree of Bai Jian.The utility model integrates multiple measurement, calibration function, and all measuring operation easily and fast, accurately greatly facilitate the calibration of fingerboard.

Claims

1, fingerboard calibrating device, it is characterized in that: the bulk that slightly is rectangle, a rectangular side caves inward and forms a groove, the degree of depth of this groove equals the standard depth of black key, another side outwards protrudes and forms a boss, the height of this boss equals the standard depth of Bai Jian, the 3rd side outwards protrudes and slightly forms " Jiong " shape frame, the inside casing height of " Jiong " shape frame equals the calibrated altitude of black key, the housing height of " Jiong " shape frame equals the calibrated altitude of Bai Jian, and four side is flat.
