Novel music box structure

Abstract

The invention discloses a novel music box structure. The novel music box structure comprises an articulating box, supporting plates are installed on the two sides of the lower end face of the articulating box, a rotating hole is formed in the articulating box, a rotating rod is rotationally installed in the rotating hole, a rotating plate is installed on the upper end face of the rotating rod, anda connecting rod is installed on the rotating rod. The rotating plate is rotated, and drives circular cover plates to rotate, the shielding area of the circular cover plates for sound discharging holes is changed accordingly, and the sound of a music box is conveniently changed; bent-angle rods support the middle sides of the front ends and the back ends of articulating plates, and the anti-bending-deformation strength of the middles of the articulating plates can be effectively improved; when the articulating plates are shifted and bent through articulating protrusions, the articulating plates can be rapidly sprung back to the original state, and the articulating plates are not prone to bending and deformation under using for a long time; pulling plates are pulled on the inner sides to drive inserting rods to be separated from inserting grooves, the pulling plates are pulled downwards, a fixing plate is separated from a square hole, new articulating plates and fixing plates are inserted into the lower port of the square hole, and the articulating plates are conveniently replaced.

Description

technical field [0001] The invention relates to a novel music box structure. Background technique [0002] The craftsmanship of the music box is exquisite, and its clear and translucent sound quality brings wonderful enjoyment to people. Now the music box has become a good gift for people to visit relatives and friends. [0003] In the existing music box, the handle is rotated to drive the dial wheel to rotate, so that the dial protrusion set on the dial wheel according to the music score rotates and stirs the sound board, so that the sound board vibrates and emits sound and the music is released from the sound box. The sound discharge hole on the upper end discharges the pronunciation box. The disadvantages are: first, some occasions require a smaller sound, and some occasions require a louder sound. Because the size of the sound discharge hole of the pronunciation box itself is constant, the sound discharge of the pronunciation box itself cannot be changed. The size of th...
