Title: Combined stand and acoustic board for musician
IPC: G10K11/28
Filed: 1985-09-09
Abstract: The present invention relates to a device consisting of a music stand which is extended upwards by a board designed to reflect the sounds of a musical instrument such as the guitar, the violoncello or any other similar instrument. This combined stand and reflective acoustic board, which is of an appropriate shape and is placed in front of the musician while he plays, reflects back to his ears the sounds emitted and projected forwards by his instrument. It is universally admitted that a guitarist, for example, hears the sound of his own guitar less clearly than a listener placed in front of him. By placing the acoustic panel in front of himself, he hears his guitar as if he were in front of it: sound quality and strength much greater.
