Description

Automatic musical box

The utility model relates to a kind of music box, and it is applicable to deposits jewellery, souvenir and gift other people as gift box.

The music box of prior art, its music generator is mechanical, and it can only playing back music, can not play language.This mechanical type music generator comprises: the soundboard of clockwork spring, band sheet metal, the rotating cylinder and the switch of band small lugs.Its principle of work is: after tightening clockwork spring, open the lid, clockwork spring drives the rotating cylinder with small lugs and rotates, because the small lugs on the rotating cylinder is arranged according to certain rules, therefore, along with the uniform rotation of rotating cylinder, these small lugs of arranging according to certain rules collide soundboard regularly, thereby produce sound clocklike, form musical composition.This mechanical type music generator, complex structure, volume is big, and cost is higher, and voice are single, and because it mainly relies on mechanical drive and metal bump pronunciation, so it installs difficulty, serviceable life is short simultaneously.

The purpose of this utility model is in order to overcome the shortcoming of prior art, provide a kind of simple in structure, volume is little, the music box of with low cost, long service life.

Technical solution of the present utility model is: music box comprises lid, box body and sound generator, it is characterized in that sound generator is made up of switch, music IC sheet, battery and hummer, wherein switch is arranged on the hinge place, and it comprises hinge, switch plate and the contact that connects lid and box body; Switch plate is flexible, can live hinge by hasp, and contact is positioned at switch plate inner face and insulation with it, and the two is connected to respectively on two control pins of music IC sheet, constitutes switch of the present utility model by hinge, switch plate and contact; The power supply input pin of battery and music IC sheet links, the signal output pin connection of hummer and music IC sheet.

Compared with prior art, the utlity model has following advantage:

(1) sound generator has adopted electroacoustic techniques, and the sound generator volume is little, in light weight, makes the utility model simple in structure, with low cost.(2) the hinge switch is hidden at the music box edge, does not take the space of box, so box is rationally distributed, the utilization factor height.(3) the electronics music box can be selected different IC sheets as required for use, makes the utility model change musical film easily, increases new kind; Therefore, the music box of playing a piece of music or many songs can be arranged not only, and can play the music box of language in addition, this is that the mechanical type music box can't be realized.(4) the used components and parts of sound generator are few, and the power consumption of these components and parts is all very little, so the utility model power consumption is minimum, long service life.

Below in conjunction with accompanying drawing the utility model is described in detail:

Cut-open view when Fig. 1 is the utility model pass upper box cover 10.

Fig. 2 is the cut-open view that the utility model opened the lid 10 o'clock.

Fig. 3 is the electrical principle block diagram of the utility model sound generator.

Fig. 4 is that the D of switch plate 21 of the present utility model is to view.

Fig. 5 is that the E of switch plate 21 of the present utility model is to view.

Fig. 1, Fig. 2, Fig. 3 and music box shown in Figure 4 are one of embodiment of the present utility model.Music box comprises lid 10, box body 11 and sound generator.It is characterized in that sound generator is by switch 12, music IC sheet 13, battery 14 and hummer 15 are formed, wherein music IC sheet 13 adopts 5201 IC sheets, switch is arranged on hinge 20 places, it comprises the hinge 20 that connects lid 10 and box body 11, switch plate 21 and the contact 22 that is positioned at switch plate 21 centres, on two pages of sheets of hinge 20, a groove is arranged respectively, switch plate 21 is one to be the spring leaf of arcuation, two ends band crotch, make its energy hasp live the groove of hinge 20, contact 22 is leads that are wrapped on the

switch plate

21,21 insulation of it and switch plate, contact 22 and switch plate 21 respectively with two control pins 1 of

music IC sheet

13,2 link; Battery 14 adopts button cells, and its magnitude of voltage is 1.5V, and the power

supply input pin

3,4 of it and music IC sheet 13 links; Hummer 15 adopts flat hummer, and the

signal output pin

5,6 of it and music IC sheet 13 links; As can be seen from Figure 1, when lid 10 was shut, switch plate 21 had only the two ends hasp to live hinge 20, the centre protuberance, and contact 22 does not contact hinge 20, and switch 12 disconnects; As can be seen from Figure 2, when lid 10 is opened, β angle＜180 of 20 two pages of sheets of hinge °, switch plate 21 is strained by hinge 20, and contact 22 relies on hinge 20 and contact with it, switch 12 conductings, sound generator sends music.

Fig. 1, Fig. 2, Fig. 3 and music box shown in Figure 5 are another embodiment of the present utility model, different with embodiment one is: the music IC sheet 13 in the present embodiment adopts the 5202IC sheets, battery adopts button cell, its magnitude of voltage is 3.0V, contact 22 is sheet metals that are positioned at the center of switch plate 21 and insulate with it, it connects by the control pin of lead with music IC sheet 13, and all the other implementation methods are with embodiment one.
