Abstract

The invention discloses a mobile phone terminal based piano tuning system. The mobile phone terminal based piano tuning system comprises a sound sensor used for receiving piano sound signals, a piano sound signal preprocessor, a user intelligent mobile phone terminal, a cloud server and tuner intelligent mobile phone terminals; the sound sensor is arranged at the inner side of a piano shell and is close to the edge of the piano string which corresponds to a to-be-measured tone; the signal output end of the sound senor is connected with the signal input end of the signal preprocessor; the signal output end of the signal preprocessor is connected with the signal input end of the user intelligent mobile phone; the signal output end of the user intelligent mobile phone is connected with the database input end of the cloud server; and the database signal output end of the cloud server is respectively connected with the signal input ends of multiple tuner intelligent mobile phone terminals. The mobile phone terminal based piano tuning system provides services for users with piano tuning requirements, reduces requirements of piano tuning for professional special crowds and improves piano tuning precision.

Description

technical field [0001] The invention relates to a tuning system, in particular to a mobile phone-based piano tuning system. Background technique [0002] The current piano tuning technology mainly relies on manual tuning, and the requirements for tuning personnel are very high, and they need to have a very sensitive piano tone recognition ability. Although there are many existing related mechanical equipment, due to the immature technology, the analysis of the signal and the display of the results require a computer, or even some other special equipment, which cannot be applied to the most commonly used and most convenient mobile phone. Still biased towards manual tuning. Because the manual tuning is mainly for the tuner to judge the pitch of the piano based on the sound of the piano heard by the human ear, and then use the tuning tool to adjust the strings. This whole process is not only very cumbersome, but also highly demanding for professionals, and the accuracy is not...
