A system for fixing and tensioning strings of a stringed musical instrument comprises a string holder provided on one end of a neck, an upper nut provided on a second end of the neck and adjusting screw mechanisms in an amount that corresponds to the amount of strings, while each of the strings is configured so that its first end can be fixed in the string holder, the second end can be passed through grooves of the upper nut and fixed on the adjusting screw mechanism. An arrangement for directing the strings is mounted after the upper nut on a face surface of the neck, in a form of a curved plate, which has guides for the strings provided therein. The adjusting screw mechanisms are arranged at an acute angle relative to the longitudinal axis of the neck in a frame fixed on a back surface of the neck. A neck reinforcement member can be mounted in a central portion of the neck along the entire length.

System for fixing and tensioning strings of a stringed musical instrument

The invention relates to the field of plucked string musical instruments, specifically to designs of electric musical instruments which transform mechanical vibration of strings into electrical signals, more particularly to compact electronic guitars, and can be used in portable electronic guitars. The application of the invention claimed allows to create a compact electronic guitar that can be quickly assembled/disassembled, while the string elasticity level remains the same in both disassembled and assembled states (making the guitar immediately available for use once the parts of the body have been connected) and to provide the possibility to obtain information about vibrations and excursions of the strings located on the neck occurring as a result of using various playing techniques requiring certain actions to be taken in relation to the strings located on the neck, such as hitting, displacing the pressed string sideward, sudden pressing down of the string and sudden releasing of the pressed string, moving the finger along the string, either pressed or not. This provides the possibility to use a larger number of events occurring with the string to generate acoustic oscillations.

Compact electronic guitar

The inventions relate to the field of electric musical instruments, more particularly, to an optical sensor for a stringed musical instrument with a digital interface and to a stringed musical instrument with a digital interface equipped with said sensor (MIDI&#x2014;Musical Instrument Digital Interface). Implementation of the disclosed inventions allows to obtain a signal corresponding to vibrations (deflections) of a string in two mutually perpendicular planes, with the influence of the device generating such signals on string vibration parameters being reduced, without signals generated by different strings being mixed and with dimensions of the optical sensor being reduced to allow for its compact placement on a stringed musical instrument.
