Embodiment Construction

[0021] The technical scheme of the present invention will be further described below in conjunction with accompanying drawing and preferred embodiment:

[0022] refer to figure 1 As shown in , the piano tuning detection device of the present invention includes: a laser identification sticker, a laser head, a central processing unit, a storage unit, a display unit and an adjustment device. The light from the laser head is irradiated vertically on the laser identification sticker, and at the same time, it receives the light reflected from the marking area set on the laser identification sticker. The laser head, storage unit, display unit and adjustment device are respectively connected to the central processing unit.

[0023] The laser identification sticker is a film of light and thin material, which can be directly attached to the strings of the piano without affecting the normal vibration of the strings. When the strings vibrate, the laser identification stickers will vibrate...

Abstract

A piano tuning detection device and an implementation method thereof relate to the technical field of piano tuning, and in particular, to a device and a method for detecting a string frequency in the process of tuning a piano, which solves the technical problem that the professional requirement is high, the tuning precision is poor, and the operation is inconvenient in the existing piano tuning work. The tuning detection method comprises the following steps: a. sticking a laser recognition sticker on a string to be detected; b. illuminating the laser recognition sticker with a light ray from a laser head; c. pressing a key corresponding to the string to be detected; d. providing a detection signal source to a central processing unit to detect an actual frequency value of the string; and e. performing comparison. The piano tuning operation is implemented according to the principle that the laser head reads a disc in a driver without requiring a special auditory sense of a tuning person. The piano tuning operation can be accomplished by a common operator, so the operation is convenient and the tuning precision is high.

Description

technical field [0001] The invention relates to the technical field of piano tuning, in particular to a device and a detection method for string frequency detection during the piano tuning process. Background technique [0002] Piano tuning is a highly professional job. The tuner needs to have a very sensitive sense of hearing, be able to recognize this job, and be able to adjust the sound of the piano well. Generally, only blind people who are uniquely sensitive to sound to do it. However, with the development of society and the popularization of pianos in ordinary families, the tuners who can win the piano tuning work are far from meeting people's needs. [0003] Chinese patent No. is: 97123257.1 discloses a kind of piano tuning standard generator, when this generator is used for piano tuning, detects and displays the sound frequency corresponding to each key of the tuned piano, and shows the standard audio frequency simultaneously, which is consistent with the standard t...
