Description

A Dong Nationality Dage Music Box

technical field

The utility model relates to a Dage music box of the Dong nationality, which belongs to the technical field of music box structures.

Background technique

The existing music box is composed of sound tube, sound board, gear, spring (or other power source), damping and other components in the movement of the music box. The sound number of the movement we refer to means that the sound board can effectively pronounce In the rotation movement, the bump on the sound tube stirs up the soundboard to vibrate the soundboard, and emits sound according to the designed vibration frequency. However, the existing music box has a single shape and structure, and the music type is also relatively single. The music box doesn't last long.

Contents of the invention

The purpose of this utility model is: aim at the defect of the prior art, provide a kind of music box of the big songs of the Dong nationality, adopt the circuit control to realize the automatic operation, and integrate the national characteristics, the structure is novel, so as to overcome the deficiencies of the prior art.

Technical scheme of the utility model

A Dage music box of the Dong nationality, comprising a cylindrical chassis, the middle part of which is a regular octagonal groove, the drum tower of the Dong nationality is arranged on the groove through a support rod, the regular octagonal bell mouth is arranged around the groove, and the horn is arranged in the bell mouth A symmetrical opening along the center line of the chassis is arranged on the extension of the chassis surface, a pressure sensor with a top plate is arranged in the chassis and corresponds to the position of the opening, and the pressure sensor and the horn are connected through a control circuit.

In the aforementioned Dage music box of the Dong nationality, the size of the top plate is consistent with the size of the opening.

In the aforementioned Dage music box of the Dong nationality, the groove, the bell mouth and the surface of the chassis form a stepped structure.

Due to the adoption of the above-mentioned technical scheme, compared with the prior art, the utility model realizes the automatic operation of the music box through the pressure sensor, places the Dong dolls prepared on the top plate of the pressure sensor, and realizes the music of different music through the dolls of different weights. Playing, when the doll is not placed, the top and the opening fit together to realize the chassis surface as a whole, the groove, the bell mouth and the chassis surface form a ladder-like structure and the drum tower of the Dong nationality as a whole structure, so that the music can be surrounded when playing music. Realize a more obvious three-dimensional auditory effect (regular polygon structure is more conducive to the surround effect of music), the utility model is simple in structure, easy to manufacture, has a unique national style, and has good ornamental value under the condition of ensuring the quality of the music box and collection value.

Detailed ways

The utility model is used as a further detailed description below in conjunction with the accompanying drawings, but not as any limitation to the utility model.

Embodiment of the present utility model: a kind of Dong nationality big song music box, as shown in accompanying drawing 1, comprises cylindrical chassis 1, and this chassis 1 middle part is regular octagonal groove 2, and Dong nationality drum tower 3 is arranged on the concave groove by support bar 4 On the groove 2, a regular octagonal bell mouth 5 is arranged around the groove 2, and the horn is arranged in the bell mouth 5. On the extension of the surface of the chassis 1, there is a symmetrical opening 6 along the center line of the chassis 1, and a pressure sensor with a top plate 7 8 is arranged in the chassis 1 and corresponds to the position of the opening 6. The size of the top plate 7 is consistent with the size of the opening 6. The pressure sensor 8 and the horn are connected through a control circuit. The control circuit is shown in Figure 2, in which the groove 2, the horn The mouth 5 and the surface of the chassis 1 form a stepped structure.

When in use, turn on the switch of the control circuit, place a Dong doll on each top board, and play music through the weight of the Dong doll (dolls with different weights can play different music, and can also place multiple dolls at the same time, Realize the sequential playback of different music).
