Automatic guitar tuning case

Abstract

An automatic guitar tuning case is a tuning system to automatically, synchronously, accurately and rapidly turn a guitar. To automatically tune one string is not new, but automatically and synchronously tune an acoustic guitar or electrical guitar without modifying the guitar has never be done before. Changing one string's tension will cause all other strings' tension change, so all strings should be tuned synchronously and ended tuning together only when all strings are in tone at the same time. As a closed-loop control system, the automatic guitar tuning case comprises six transducers sensing the vibration frequency of six guitar strings respectively, six tuner units to analyze tones, and a center processor unit to control six electric tuning wrenches to tune the six guitar strings. The automatic guitar tuning case also consists of a control panel for a user to preset and select tuning patterns, control and monitor the system. To tune a guitar with this invention just need to put a guitar in the case and close the lid, the guitar will be in tone in seconds. It doesn't require installing any components, means or devices on the guitar or modifying the guitar. It can either work on an acoustic guitar or electric guitar regardless of the gauge and material of the strings. This invention could be a tuning case to serve a specific guitar, or be a tool to serve a batch of the same model guitars or serve different model guitars with a little adjustment.
