Device for sound recording, signal processing and integration of common operating parts and interfaces, with a particularly simple installation option without structural changes or acoustic impairment for acoustic stringed instruments, in particular for acoustic guitars

摘要

A bearing anchor (11) may be moved or set along a section of the circumference of the rose (2) on or under the soundboard. Thanks to an appropriate design of the bearing anchor, it serves as a holder for one or several sound sensors (6), together with their associated lines, and may be introduced into the instrument through the rose, passing by the strings. The bearing anchor may be linked to a belt (3, 10, 14). By an appropriate design of belt (10) and anchor (11), the belt (10) draws the bearing anchor (11) against the soundboard when it is stretched along an axis parallel to the soundboard, so that the anchor is pressed against the soundboard along a section of the circumference of the rose and is thus held in place.
