PROBLEM TO BE SOLVED: To provide sound quality which is superior to that of a conventional device, associated with musical instruments and the like/sound equipment and the like, by making a housing sound, using a device mounted with a mineral. SOLUTION: A part having a shape such that vibrations of a sound are easily transmitted or metal 1, and the like, in a screw shape is prepared, and an acute portion of the mineral 2 which sufficiently withstands the force of vibrations is directed downward and anchored to a flat part of the top so that a noise is not generated due to loosening, and the like. Then the device is fitted in a passage of a sound and vibrations of musical instruments and the like, and sound equipment and the like, or in a place where the sound and vibrations are collected.
