装置。[Scope of Claim for Utility Model Registration] (1) In a music box pick-up device that uses a piezoelectric element to detect the vibration of a comb-like vibration valve provided on a diaphragm and convert it into an electrical signal, the piezoelectric element is fixed to the diaphragm. A pickup device for a music box having a structure in which a detection voltage for vibration changes along the arrangement of the vibration valves on a side surface of a pedestal that is parallel to the direction in which the vibration valves are arranged in pitch order. (2) In the music box pickup device according to claim 1, the configuration in which the detection voltage of the piezoelectric element in response to vibration changes along the arrangement of the vibration valves means a change in the shape or thickness of the piezoelectric element, or a change in the thickness of the piezoelectric element. A music box pick-up device characterized by dividing, changing the material, selecting the position along the arrangement direction of the vibrating valves, or a combination thereof.
