Tuning method and system for stringed instrument

Abstract

The invention discloses a tuning method for a stringed instrument. The method comprises a step of setting an adjusting device to adjust the pulling force of strings, a step of setting force sensors toreflect the tension of the strings, a step of setting a pickup device to pick up the sound of the strings, and a step of setting a main control device to control the adjusting device based on reflection signals of the force sensors and a sound signal of the pickup device. The present invention also discloses a stringed instrument tuning system based on the above method. According to the invention, the force sensors are used to reflect the tension of the strings, based on the signals of the force sensors and the pickup device, the operation of the motor is controlled, and more accurate and efficient tuning can be achieved compared with the prior art.

Description

technical field [0001] The invention relates to the field of stringed musical instruments, in particular to a stringed musical instrument tuning method and system. Background technique [0002] The pronunciation of stringed instruments relies on mechanical force to vibrate the tensioned strings. When the tension on the strings exceeds the limit, the pronunciation will be deformed, and even the strings will be broken. Stringed instruments usually use different strings to play different tones, and sometimes you have to use your fingers to press the strings to change the length of the strings, so as to achieve the purpose of changing the pitch. Stringed instruments are mainly divided into plucked string instruments (such as guitar and ruan), drawn string instruments (such as violin and huqin) and percussion instruments (dulcimer) in terms of their pronunciation. [0003] The pronunciation of strings is the result of the combined effects of many factors, including the vibration...

Problems solved by technology

Such an adjustment can achieve the purpose of tuning, but the tuning cannot be saved, and the steps of monitoring and adjustment need to be repeated frequently before each use, and the strings need to be tightened manually when the strings are loose and cannot produce sound. Not only does it take a long time, it increases the inconvenience of use, but also puts forward higher requirements for the performance of each component, the cost is higher, the structure is more complicated, and more importantly, the monitored vibration frequency signal is easily disturbed by external vibration. Reduce the credibility of the monitored samples and affect the accuracy of tuning
