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

The invention discloses a piano tone tuning device and an implementation method thereof and relates to the technical field of piano tone tuning, in particular to a device and a method for detecting the string frequency during tone tuning of a piano. The technical problems of high specialty requirement, low tuning accuracy and inconvenience in operation in the conventional piano tone tuning work are solved so as to implement the tone tuning detection method. The method comprises the following steps of: a, adhering a laser identification paste on a string to be detected; b, allowing the light ray of a laser head to irradiate on the laser identification paste; c, pressing a key corresponding to the string to be detected; d, providing a detection signal source for a central processing unit, and detecting the actual frequency value of the string; and e, comparing. According to a principle that the laser head reads a disk in a CD-driver, the tone tuning operation of the piano is realized, special requirements on hearing of tuning staff are avoided, common operation staff can finish the operation, and the method is convenient to operate and is high in tuning accuracy.

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...
