The Risoux forest, located in the Jura massif, is the home of the resonance wood (spruce). Used by the best violin makers, these multicentennial trees are endowed with exceptional sound qualities. This acoustic board, worked by hand like a guitar soundboard, allows, through a vibrator and a bluetooth connection, the resonance of the wood and thus the diffusion of music. With its crystalline sound, this sculptural object offers an alternative way to listen to relaxing music (jazz, classical, folk). This product is handmade by local craftsmen and use only local and natural resources. The aim is to propose an affordable speaker by demonstrating the potential of natural resources used through a relevant way.
