Abstract

The invention provides a piano tuning method. A tuning system used comprises a received sound comparison and control system, an automatic tuning and sound stopping device, an automatic playing deviceand a support platform, wherein the received sound comparison and control system comprises a sound reception microphone, a comparison system, a logic system and a control system; the automatic tuningand sound stopping device comprises an automatic tuning device and a sound stopping device; the automatic playing device comprises a positioning platform, a power box, a moving screw, a guide rail, apositioning bracket, a rubber fingertip, a moving platform, a torque motor and a mechanical arm. Key overtones are recorded by the sound reception microphone in the received sound comparison and control system and converted into digital signals, the digital signals are stored in the received sound comparison and control system for comparison, the overtone interference caused by music wire vibration is excluded to improve the accuracy of sound reception, at the same time, the tension on music wires is monitored in real time to protect the music wires from being broken by tuning.

Description

technical field [0001] The invention relates to piano tuning, in particular to a piano tuning method. Background technique [0002] At present, manual tuning is labor-intensive and expensive, and the tuning process mainly relies on the auditory experience of technicians, which may cause large errors. Patent CN2010101138025 discloses an automatic tuning device for pianos. The automatic tuning device includes an audio input device and a filter. The audio input device is connected to the filter. The filter is connected with the waveform amplifier, the waveform filtered by the filter is amplified by the waveform amplifier, the waveform amplifier is connected with the waveform shaping circuit, the sound wave is input to the central processing unit after being shaped by the waveform shaping circuit, and the central processing unit The standard frequency processes the sound wave frequency, the central processing unit controls the drive circuit, and the drive circuit drives the adj...
