Specific embodiment

As Figure 1-5, music domino, including cuboid housing 1 and the sounding shell fragment that is arranged on inside housing 1, Sounding shell fragment is made up of vibrations shell fragment 2 and adjustable shell fragment 3, and vibrations shell fragment 2 shakes bullet together with the bottom welding of adjustable shell fragment 3 Piece 2 is cambered surface, and in the vibrations welded top tapping board 4 of shell fragment 2, the lower end of adjustable shell fragment 3 is welded with fixed plate 5, fixed plate 5 Two ends are inserted in the fixed seat 6 of the inside both sides of housing 1, and the housing 1 of the upper end of adjustable shell fragment 3 is internally provided with section for isosceles trapezoid Public address hood 7, and the upper end open of public address hood 7 is larger, and is provided with sound hole 8, adjustable shell fragment 3 on the wall of housing 1 of the opening of public address hood 7 On be cased with shell fragment slide fix bar 9, shell fragment slide fix bar 9 two ends be respectively provided with rotation block set 10, two fixed threaded posts 11 are respectively fitted in rotation block set 10, and one end that fixed threaded post 11 is located in rotation block set 10 is fixed with back-up ring 12, every Fixed threaded post 11 extends through the strip threaded post slideway 13 of the both sides of housing 1, and the both sides of threaded post slideway 13 of each side are also divided Not She Zhi gripping block slide rail 14, the opposite spiral shell in direction of rotation is respectively provided with the fixed threaded post 11 of the both sides of threaded post slideway 13 Screw shell 15 is cased with respectively on opposite screw thread on line, and every fixed threaded post 11, in the peripheral grooves of screw shell 15 Retainer ring 16 is cased with, retainer ring 16 is embedded in the clamping plate 17 of both sides respectively, clamping plate 17 is rectangle, every piece of 17 points of clamping plate Wei Yu not be in corresponding gripping block slide rail 14, so when fixed threaded post 11 is rotated, you can make in a fixed threaded post 11 Two screw shells 15 drive clamping plate 17 simultaneously it is to two side shiftings or simultaneously close to each other, clamping plate 17 simultaneously mutually Clamping action is just formed when being close to, is easy to fix at the two ends that shell fragment slides fix bar 9.

In order to improve the fastness that the shell fragment of clamping plate 17 slides fix bar 9, the relative side point of every piece of clamping plate 17 The rubber that section is triangle not being provided with and holding out against raised 18, rubber holds out against raised 18 and increases clamping plate 17 and threaded post slideway The frictional force of the side wall of 13 upper shell 1, makes two pieces of stronger side walls for clamping housing 1 at threaded post slideway 13 of clamping plate 17, enters And shell fragment is slided the more firm of the fixation of fix bar 9, the adjustable shell fragment 3 for making shell fragment slide between fix bar 9 and fixed plate 5 is fixed It is more firm, it is impossible to sounding, only shell fragment slide fix bar 9 upper end the part of adjustable shell fragment 3 can sounding, therefore, by regulation Shell fragment slides the length that fix bar 9 is the adjustable sounding position of adjustable shell fragment 3, the sounding position meeting of the different length of adjustable shell fragment 3 Send different sound.

Rotated for the ease of fixed threaded post 11, every fixed threaded post 11 is located at the one end point rotated in block set 10 Not She Zhi two circle balls 19 with rotation the madial wall of block set 10 contact, and wherein one enclose ball 19 also contacted with back-up ring 12.

Adjustable shell fragment 3 being tapped for the ease of tapping board 4 and sending sound, the width of the vibrations shell fragment 2 is more than adjustable shell fragment 3 Width, the thickness of tapping board 4 makes the weight of tapping board 4 larger, is easy to tap adjustable shell fragment more than the thickness of adjustable shell fragment 3 3。

After being well placed multigroup the utility model, when shifting onto, by clashing into, internal tapping board 4 is clashed into shell fragment and slide fixation The sounding position of adjustable shell fragment 3 above bar 9, produces vibrations sounding, and fix bar 9 is slided by adjusting each dominoes shell fragment The difference of position, the volume up-down for sending is different, and music is played out during such that it is able to making polylith dominoes fall down successively, because To there is public address hood 7, the sound for sending can be expanded.During production, the different outsides of dominoes housing 1 can coat different face Color, while improving sight and interest, is easy to distinguish different dominoes.

Certainly, described above is not that, to limitation of the present utility model, the utility model is also not limited to the example above, this The those of ordinary skill of technical field, in essential scope of the present utility model, change, change, addition or the replacement made, all Protection domain of the present utility model should be belonged to.
