Embodiment Construction

[0016] A precision piano tuner, comprising a casing 1, a power device, a string shaft pin sleeve 9, and a programmable control circuit. The power unit includes a stepping motor 2, a gear A3, a rotating speed device A, and a rotating speed device B. The gear A3 is installed on the rotating shaft of the stepping motor 2, and the stepping motor 2 drives the gear A3 to rotate coaxially. Speed ​​device A includes gear B4, gear C5 and shaft A6, gear B4 and gear C5 are fixed together, gear B4 rotates to drive gear C5 to rotate along the same shaft A6, speed device B includes gear D7 and shaft B8, gear D7 is fixed on shaft B8 , the gear D7 rotates to drive the rotating shaft B8 to rotate. The string shaft pin sleeve 9 is a hollow cylinder, and the hollow part is a cuboid whose cross section is a square, so that the string shaft pin sleeve 9 just in time is enclosed within the string shaft pin of the piano. The shell 1 is in the shape of a cuboid as a whole, and is used for installin...

Abstract

The invention discloses a precise piano tuner which comprises a shell, a power device, a string shaft pin sleeve and a programmable control circuit. The power device comprises a stepping motor, a gearA, a first rotating speed device and a second rotating speed device. The rotation angle of the stepping motor is controlled by the programmable control circuit, four buttons are connected with the programmable control circuit, the corresponding buttons are respectively pressed several times according to the amount of high or low tones, and the tightness of the strings can be adjusted to achieve accurate tuning. The piano tuning device overcomes the defects of an existing tuning method, has the advantages of being labor-saving in tuning, short in consumed time, accurate in tuning, simple in structure, low in production cost and the like, and can be used for easily realizing piano accurate tuning of families, schools and the like without professional piano tuners.

Description

technical field [0001] The invention mainly relates to the field of tuners, in particular to a precision piano tuner. Background technique [0002] At present, when the piano is played for a period of time and needs to be tuned, a tuner with tuning experience is usually asked to perform the tuning. The tuner usually uses a tuning wrench to tighten or loosen the strings to make it reach a certain pitch. On the one hand, using a tuning wrench is very laborious. On the other hand, when the frequency is corrected to within ±5Hz, it is time-consuming. A piano usually has more than 200 strings, and each string is corrected to an error within ±5Hz. Within a few days, the tuner needs to spend at least one day. When the frequency is corrected to the error within ± 2Hz, it is more difficult. It takes a lot of time for the tuner with many years of tuning experience to achieve it. When the frequency is corrected to the error within ± 1Hz It is more difficult when it is within, almost i...
