From Fig. 1 to Fig. 7 reflection is an embodiment of Miniature 8-tone organ of the present invention.It includes the size base plate more much smaller than conventional musical box (1), is fixed with soundboard (2) on base plate (1), sounding drum (3) and clockwork spring assembly, gear drive train and governor assembly.The clockwork spring assembly further includes clockwork spring shell (4), clockwork spring (5), winder (6), non-return spring (7).At clockwork spring shell (4) an outwards outstanding little spindle nose (8) is arranged on that sidewall of sounding drum, the mutual pivot of the interior formation of central dead eye (10) that it inserts sounding drum mill pinlon (9) props up (see figure 4), such connectivity scenario has been avoided the shortcoming in the conventional solution, in conventional art spindle nose be positioned at outside the mediad of sounding drum mill pinlon outstanding, and dead eye is opened on the described wall of clockwork spring shell, reduced the intensity of this wall of clockwork spring shell like this, the present invention's design has overcome this shortcoming.
Speed governing dampened disk (11) in the present embodiment governor assembly is embedded in the recessed round platform (12) of base plate (1), like this, by the just speed governing axle (14) of a band worm screw (26) of speed-regulating rack (13) containing, so speed-regulating rack (13) can be done very simply and the duty volume is very little, what present embodiment adopted is
The speed-regulating rack of font.Because speed governing damper (11) has moved down in the base plate (1) from position, speed-regulating rack middle and upper part, also just disappeared with the damping frictional disk of described dampened disk (11) coupling, perisporium by the recessed round platform of musical movements baseboard (1) (12) replaces, so speed regulator support (13) is as long as adopt one
The thin frame of font just.Such layout also provides convenience for parking constantly and the starting that needs for the contraposition of dialling sound pin (16) on the key (15) of adjusting soundboard (2) and the sounding drum in the musical box production run.Because dampened disk (11) is embedded in the base plate (1), and speed-regulating rack (13) is tiny, many spaces have been abdicated, be convenient to the operator and remove to contact dampened disk (11) in rotating at the time standby finger of holding that musical box adjusts, the musical box complete machine will be at once by stop, and this has just made things convenient for operator's adjustment.And dampened disk (11) and clockwork spring shell (4) be located by connecting also very succinctly mutually, adopt catching groove (17) and colluding of clasp (18) to close connected mode, make between the two deciliter all very convenient.As can be seen from Fig. 2, there are speed governing axis hole (19) and coupled reinforcement (20) in speed-regulating rack (13) inside top surface central authorities, side along reinforcement (20) has a catching groove (17), and it matches with the clasp (18) of top, clockwork spring shell (4) one sides, constitutes removable lining connection.Speed-regulating rack (13)
The font frame can be a detachable with being connected of base plate (1), fix with screw (21) this moment, also can be fixed, but the meeting of making detached type be convenient to change the dampened disk (11) of different size size, when adopting fixed connection, can connects with rivet.
In order to reduce manufacturing cost, material cost, raising manufacturing accuracy and transmission efficiency, in the present embodiment with mill pinlon (9), non-return spring (7), great wheel, cross gear (24), worm gear (25) and all be designed to plastics.The plastic of these parts can increase the duty volume, but the solution of the present invention has solved this contradiction because dampened disk (11) has been imbedded in the base plate (1) thereby reserved enough spaces above base plate.
Size characteristic about soundboard (2) is shown in among Fig. 6 and Fig. 7, (just the interval S between the every adjacent key of soundboard is controlled between 0.75～0.85mm spacing between the every adjacent group of sound pin (16) of sounding drum, the wide B of key of soundboard (2) is 0.40～0.60mm, soundboard (2) thickness of slab h is 1.2～1.7mm, bass bond distance L2 is 11.5～13.5mm, the bass buttons minimum wall thickness (MINI W.) is greater than 0.15mm, high pitch key length L1 is 8.75～10.75mm, key oblique angle θ is 8 °～20 °, so musical box of the present invention, its sounding drum (3) and soundboard (2) have all been realized microminiaturization.
