PURPOSE: A guitar string regulator is provided to enable even hearing impaired people and visual impaired people to regulate the string of a guitar and prevent the string from being broken. CONSTITUTION: A guitar string regulator comprises a sensor unit(4), a frequency converter(3), a microprocessor(1), and a drive part. The frequency converter converts sensed sound into frequency and transmits the frequency to a microprocessor. The microprocessor stores the frequency of the fundamental tone which is selected. The selected microprocessor transmits control signals so that the frequency of the string of the guitar may be in accord with delivered frequency. The drive part moves the string of the guitar to the fixed location. |
