It is set according to such diameter of axle, by the way that the diameter of axle of drive shaft 311 and the driven shaft 321,322 of side of first stage is formed For the smaller structure of the driven shaft diameter of axle than rear stage side, the friction so as to reduce bearing ensures swimmingly to rotate startup, And by by the diameter of axle of axle 114 and the driven shaft of rear stage side 323,324 be formed as than first stage side the driven shaft diameter of axle more Big structure ensures that power transmits so as to bear rotary load.In addition, in this example, the diameter of axle of third driven shaft 323 exists It is the largest among driven shaft, this, which allows for ratchet pawl etc., can apply larger thrust load.

As shown in figure 8, the small of the horizontal gear rotated integrally with axis 311 is installed in the drive shaft 311 of ac motor 31 Diameter gear 317.In addition, be equipped in first driven shaft 321 with axis 321 rotate integrally by large diameter gear 321a and small-diameter gear 2 horizontal gears that 321b is formed.In addition, be equipped in second driven shaft 322 with axis 322 rotate integrally by large diameter gear 3 horizontal gears that 322a, central diameter gear 322b and small-diameter gear 322c are formed.

It is equipped on third driven shaft 323 and is made of large diameter gear 323a, central diameter gear 323b and small-diameter gear 323c 3 horizontal gears.In this 3 gears, large diameter gear 323a is adjacent to central diameter gear 323b, and is rotated integrally with axis 323 While can back and forth be slided in predetermined stroke along axis 323.On the other hand, small-diameter gear 323c and 2 gear 323a, 323b is separately positioned, and can in linkage be slided with 2 gears 323a, 323b.Moreover, small-diameter gear 323c can be by rear The clutch stated is combined with axis 323.That is, when above-mentioned clutch connection, rotate integrally, and work as with 2 gears 323a, 323b During clutch separation, 2 gears 323a, 323b are free state.

The central diameter gear 324a of the horizontal gear rotated integrally with axis 324 is provided on 4th driven shaft 324.Moreover, trailing wheel Axle 114 on be provided with the central diameter gear 114c of the horizontal gear rotated integrally with axis 114.

Above-mentioned 4 driven shafts 321 ~ 324, as shown in figure 8, to disperse in the up-down direction and abutted with drive shaft 311 State whole centralized configuration is in the superjacent air space of axle 114, so as to different from previous this train of reduction gears, has no need to ensure that The storage space in the front-back direction of car body is sufficiently large, and therefore, the driving unit 3 of the utility model can compactly be accommodated in train The rear vehicle of toy.

Further, since drive shaft 311, a series of driven shaft 321 ~ 324 and axle 114 are parallel to each other, therefore can be with Can only have by a series of horizontal gear group 317,321a, 321b, 322a, 322b, 322c, 323a, 323b, 323c, 324a Effect ground transmitting rotary power.That is, it will not generate previous like that as the slippages caused by crown gear.

About gear displacement mechanism

Hereinafter, gear displacement mechanism is illustrated referring especially to Fig. 6, Fig. 7 and Fig. 8.Above-mentioned train of reduction gears 32 includes First gear displacement mechanism and second gear displacement mechanism.Wherein, first gear displacement mechanism, according to specific operating parts （Operating lever 33）First operation（Slide between OFF position and ON positions）, by by particular gear（Gear 323c） Displacement is carried out in axial direction, makes particular gear and adjacent gear（324a）Between intermeshing or engagement releasing, so as to The drive shaft 311 for connecting or cutting off the rotor is transmitted to the rotary power of axle 114, in addition, second gear displacement mechanism, root According to specific operating parts（Operating lever 33）Second operation（Slide between ON positions and HI positions）, it is specific by inciting somebody to action Gear（Some in 2 gears 323a, 323b）Displacement is carried out in axial direction, makes particular gear and other gear（Gear Some in 322b, 322c）Intermeshing, the drive shaft 311 so as to change the rotor are transmitted to the rotation of axle 114 The reduction ratio of power.

Specifically, above-mentioned first gear displacement mechanism and second gear displacement mechanism passes through specific displacement operation machine Structure is operated.The displacement operation mechanism includes operating lever 33, lobe plate 33a, cam follower 33b.Wherein, operating lever 33, End is prominent and vertical with housing to outside housing from slot 121 is oriented to thereon.Lobe plate 33a, the lower end with operating lever 33 Connection, and with horizontal posture it is freely slidable be supported on car body front-rear direction, and have on its lateral edges as flat The edge cam 33g for the wavy curve shape that plane cam works.Cam follower 33b has and is formed as downward " U（Japanese Word）" font and the clamping part 33b of 2 gears 323a, 323b is clamped, and with can be in the width of car body along guide wheel 33c Protruding portion 33f that is slidably being supported on direction and being in contact with the edge cam 33g of the lobe plate 33a.

The edge cam 33g for being formed in lobe plate 33a is formed with wavy parallax, so as to the front side horizontal overhang of car body Overhang more horizontal than rear side is big.The centre of the parallax is formed with 3 of the protruding portion 33f insertions for cam follower 33b Groove.Meanwhile cam follower 33b is pressed by compressed spring 33e, is pushed into edge cam 33g sides.

Therefore, when operating lever 33 slides into HI positions from OFF position, according to the guiding of the parallax of edge cam 33g, Cam follower 33b is pushed by the pressure of compressed spring 33d, so as to be moved to close to the direction of lobe plate 33a.And work as When operating lever 33 slides into OFF position from HI positions, cam follower 33b resists the pressure of compressed spring 33d, thus to separate The direction movement of lobe plate 33a.

In addition, when operating lever 33 is moved to OFF position from ON positions, with the power-on switch 44 of flaky switch structure formation （With reference to figure 17）OFF state is switched to from ON states, stops the power supply to coil 316a, 316b of motor 31, so as to make electricity Motivation 31 becomes the state that cannot be run.

About direction of rotation limiting unit

Secondly, it is illustrated referring especially to Fig. 5 to rotating reversed limiting unit.As described above, ac motor 31 has together The function of motor is walked, direction of rotation when starting in principle is uncertain.Simultaneously as ac motor 31 is electrodynamic type The motive power of train toy, therefore when being initially powered up, the direction of rotation of limiting AC motor 31 is needed, so as to arrange electrodynamic type The car body of Toy vehicle is advanced forwards.

If rotation angle when stopping can be determined by the inertia of rotor, then can be by by near magnet branch In addition small permanent magnet pieces or magnet slice are configured at the rotational trajectory of support plate 312, so as to using the attraction of magnet, limit The position relationship between rotation angle and electrical-coil when stop is stopped stops at it and is suitble to defined direction of rotation（It is suitable Hour hands rotate or rotation counterclockwise）The position of startup.

However, in this electrodynamic type train toy, according to the increase of connection vehicle number or step on creeping away When its travel load can increased situation and in view of child's hand pressure push travel（That is manual operation）Deng situation, less Easily by the attraction between flat thin magnet as described above or magnet slice and magnetic pole, to control the stop position of magnet support disk It puts.

Therefore, in the utility model, being will be in a series of gear set set between drive shaft 311 and axle 114 Some gear is engaged with ratchet pawl 325a, so as to force limitation direction of rotation.

As shown in figure 5, side has the ratchet pawl 325a of protruding portion 325b, it is freely rotatable with ratchet shaft 325 for fulcrum Ground is supported.In this example, ratchet pawl 325a is used for the direction of rotation of large diameter gear 321a that will be installed in first driven shaft 321 It is limited to a direction.Specifically, as schemed（b）Shown, when large diameter gear 321a is rotated clockwise, ratchet pawl 325a is successively The gear teeth across on large diameter gear 321a, so as to allow its rotation.On the other hand, as schemed（c）It is shown, when large diameter gear 321a is inverse When hour hands rotate, ratchet pawl 325a is meshed with the gear teeth on large diameter gear 321a, so as to prevent its rotation.

3 kinds of meshing states about train of reduction gears

Hereinafter, referring especially to Figure 10 to Figure 12 to 3 sliding positions of operating lever 33（OFF position, ON positions, HI positions） The meshing state of corresponding train of reduction gears illustrate.

As described above, when operating lever 33 is located at OFF position, such as Figure 10（a）It is shown, pass through edge cam 33g and protrusion The contact of portion 33f, cam follower 33b resist the elastic force of compressed spring, most inboard position are press-fit into, therefore, such as Figure 10 （b）Shown, small-diameter gear 323c is released from engaging for central diameter gear 324a, such as Figure 10（c）It is shown, the rotation of small-diameter gear 323c Turn that central diameter gear 324a can not be transferred to.Trailing wheel 114a, 114b of left and right are free state as a result, and to the logical of motor 31 Electricity is also turned off, and on the other hand, as described below, continues to maintain the power supply to control circuit portion 6 under this state（Referring to figure 16）, therefore electrodynamic type train toy 100 can be pressed with hand and traveling is pushed to play.

When operating lever 33 is located at ON positions, such as Figure 11（a）It is shown, pass through connecing for edge cam 33g and protruding portion 33f Touch, cam follower 33b since the active force of compressed spring is pushed back middle section position, such as Figure 11（b）It is shown, path tooth Wheel 323c is restored with engaging for central diameter gear 324a, such as Figure 11（c）It is shown, during the rotation of small-diameter gear 323c is delivered to Diameter gear 324a.At this point, such as Fig. 9（b）Under expanded state shown in, motor 31 drive shaft 311 obtain rotary power, according to It is secondary to pass through 317 → large diameter gear of pinion gear 321a → small-diameter gear 321b → large diameter gear 322a → small-diameter gear 322c → gear After 323a → small-diameter gear 323c → central diameter gear 324a → small-diameter gear 114a is slowed down, transmitted to the axle 114 of trailing wheel, It is possible thereby to electrodynamic type train toy 100 is made to be travelled with usual speed.

When operating lever 33 is located at HI positions, such as Figure 12（a）It is shown, pass through connecing for edge cam 33g and protruding portion 33f It touches, cam follower 33b is since the active force of compressed spring is pushed back terminal location, so as to such as Figure 12（b）It is shown, path tooth Wheel 323c is restored with engaging for central diameter gear 324a, such as Figure 12（c）It is shown, during the rotation of small-diameter gear 323c is passed to Diameter gear 324a.At this point, such as Fig. 9（c）Under expanded state shown in, motor 31 drive shaft 311 obtain rotary power, according to It is secondary to pass through 317 → large diameter gear of pinion gear 321a → small-diameter gear 321b → large diameter gear 322a → central diameter gear 322b → central diameter After gear 323b → small-diameter gear 323c → central diameter gear 324a → small-diameter gear 114a is slowed down, to the axle 114 of trailing wheel It transmits, it is possible thereby to make electrodynamic type train toy 100 to be carried out at high speed traveling.

About clutch configuration

Hereinafter, clutch configuration is illustrated referring especially to Fig. 7.In second gear displacement mechanism illustrated before Spring 323d is provided with, spring 323d is used in defined gear（323c）With other gear（324a）When being meshed, buffering Reaction force when two gears engage.

That is, as shown in fig. 7, the chimera 323e with non-linear symmetric profile is provided on third driven shaft 323, this is embedding Fit 323e can be slided along axis 323 and be rotated integrally with axis 323, and chimera 323e is tied by spring 323d and gear 323a It closes.Meanwhile the side of gear 323c is formed with the embedded hole for being embedded in chimera 323e.

Therefore, when switching to ON states from OFF state, first, the freedom that gear 323c is not fitted into chimera 323e State is abutted against with gear 324a phases, then, is resisted two gears under reaction force state and is gradually engaged, finally, chimeric In the state of part 323e insertion embedded holes, the engagement of two gears is completed.Therefore, gear 323c can be suitable with engaging for gear 324a Freely carry out.

Conversion circuit is handed over about straight

Hereinafter, referring especially to Figure 17 to conversion circuit 5 is directly handed over to illustrate.As shown in figure 17, this directly hands over conversion circuit Portion is formed in the following manner, i.e., previously described scroll coil 316a and 316b are assembled as load cell, by from electricity The DC power supply supplied at pond framework 4（3V）Driving.

That is, the straight friendship conversion circuit, includes：Left side, driving transistor 51a, the 51b on right side；Left side, The driven of right side uses transistor 52a, 52b；Bridge current access 58；1 or 2 or more（It is 2 in this example）Scroll Coil 316a, 316b；Left side, pull down resistor 54a, the 54b on right side；And between electrostatic capacitance 56a, 56b and resistance 55b, 55a Series circuit.The left side, driving transistor 51a, the 51b on right side, configuration side by side, is the first conductive type mutually（This It is positive-negative-positive in example）.The left side, the driven of right side use transistor 52a, 52b, and configuration side by side, is the second conductive type mutually （It is NPN type in this example）, it is connected in series with respectively with left side, right side driving with transistor 51a, 51b, and pass through left side, the right side Control is opened and closed in the output of the driving transistor of opposite side of the side driving in transistor 51a, 51b.The bridge current Access 58 is connected in the outlet side of left side driving transistor 51a（Collector）Driving with right side is defeated with transistor 51b's Go out side（Collector）Between.Described 1 or 2 or more（It is 2 in this example）Scroll coil 316a, 316b, make Driving for left side, right side is arranged on the load cell of transistor 51a, 51b in the bridge current access 58.The left side Side, right side pull down resistor 54a, 54b, by left side, the control terminal current potential of the driving transistor on right side（Base potential）It draws Extremely（Pulldown）Open threshold potential（Base stage/transmitting pros threshold voltage）.Described electrostatic capacitance 56a, 56b and resistance 55b, The series circuit of 55a for setting auto-excitation type cycle of oscillation, is respectively arranged at the control terminal of the driving transistor 51a in left side Son（Base terminal）The leading-out terminal of driving transistor 51b with right side（Collector terminal）Between and right side driving With the control terminal of transistor 51b（Base terminal）The leading-out terminal of driving transistor 51a with left side（Collector terminal） Between.In addition, the driven control terminal side with transistor 52a, 52b of left and right（Base terminal side）On be separately provided for limiting Base resistance 53a, 53b of the left and right of base current processed.

It is as described above, identical with the number of turn using mutual coiling direction as scroll coil（Two lines when i.e., being powered Circle generates the magnetic force of same magnetic and same intensity）2 circular scroll coil 316a, 316b, and, these scroll lines 316a, 316b are enclosed, with the state being electrically connected in series mutually, is set on bridge current access 58.Also, these scroll coils As before with reference to illustrated by Fig. 4, stator side is configured at the angle interval of 180 degree by 316a, 316b.

Also, either side in electrostatic capacitance 56a, 56b of left and right（In this example, on right side）Electrostatic capacitance 56b on It is connected with to promote the resistance 57 started side by side.

By above structure, after power switch 33a is connected, by the effect for the resistance 57 for being used to promote to start, make a left side The driving unlatchings of transistor 51a earlier of side（ON）, part thereof of collector current be supplied to right side driven electricity consumption The base stage of crystal 52b, so as to which the driven of right side be made also to be opened with transistor 52b（ON）.Hereafter, the driving transistor of left and right 51a, 51b, according to the resistance value of pull-down resistance 55a, 55b of left and right and the direct capacitance magnitude and resistance of capacitance 56a, 56b 55a, 55b carry out determining auto-excitation type cycle of oscillation（Defined long period）, it is alternately carried out being opened and closed.The auto-excitation type cycle of oscillation sets It is fixed, it is to be set on the basis of considering to be actuated for the rotation of rotor induction.

So, successively via the driving transistor 51a in left side → 58 → right side of bridge current access from employing The power-on circuit of transistor 52b and successively via the driving on right side with transistor 51b → 58 → left side of bridge current access from The power-on circuit for employing transistor 52a is alternatively formed, so as to 2 coils 316a, 316b to the identical number of turn, with identical electricity Flow valuve, alternately to first direction（In figure, from left to right）It is powered and to second direction（In figure, from right to left）Led to Electricity, it is synchronous with defined auto-excitation type cycle of oscillation so as to occur on 2 coils 316a, 316b, there is identical polarity（Such as S Pole）With the situation of the magnetic pole of same intensity, alternately switch polarity.

It is now assumed that the state of Fig. 4（Permanent magnet 313a, 313c are N poles, and permanent magnet 313b, 313d are S poles）In, If it is S poles by coil 316a, 316b excitation, then permanent magnet 313b, 313d of S poles are upper to have repulsive force with regard to effect, meanwhile, Acted on permanent magnet 313a, 313c of N poles it is attractive, so as to just generate the clockwise rotary driving force of diagram on rotor （Torsion）.In addition, rotor is the permitted direction of rotation of ratchet pawl 325a clockwise.At this point, rotor clockwise after Continue after being rotated by 90 °, when coil 316a, 316b are excited as N poles, being acted on permanent magnet 313a, 313c of N poles has row Repulsion, meanwhile, acted on permanent magnet 313b, 313d of S poles it is attractive, so as to just generate the clockwise of diagram on rotor Rotary driving force.By being iteratively produced such state, after rotor clockwise starts, speed gradually increases.In addition, due to synchronization Direction of rotation is uncertain during the startup of motor, if the direction of rotary torsion is counterclockwise when starting, rotor passes through The effect of ratchet pawl 325g maintains the state that rotation stops, and in this case, wait for the cycle of oscillation of half period After clockwise rotary torsion is obtained, you can the operation more than realizing, motor just rotate clockwise startup.

When the rotary speed of rotor reaches specified value, on permanent magnet 313a ~ 313d is by coil 316a, 316b Time point（That is, the opportunity of permanent magnet and scroll interleaving coils）, the counter electromotive force arteries and veins that is sensed on coil 316a, 316b The size increase of punching, the in this way driving of left and right were in were opened at that time in transistor 51a, 51b（ON）The base of the transistor of state Electrode potential moment gets a promotion（Reverse bias）, so as at that time in unlatching（ON）The driving of state is no longer waiting for self-excitation with transistor Formula cycle of oscillation and forcibly closed（OFF）.Same effect is by repeatedly as a result, later, the driving electricity consumption of left and right is brilliant Body 51a, 51b alternately repeat opening and closing operation with the separated exciting cycle of oscillation after synchronous with every half swing circle of rotor.

So, it is identical with situation before, successively via the driving in left side transistor 51a → bridge current access 58 → right side it is driven with the power-on circuit of transistor 52b and successively via the driving on right side transistor 51b → bridge current The driven power-on circuit with transistor 52a in 58 → left side of access is alternatively formed, so as to 2 coils with the identical number of turn 316a, 316b, with identical current value, alternately to first direction（In figure, from left to right）It is powered and to second direction （In figure, from right to left）It is powered, so as to occur and be synchronized with every half revolution of rotor on 2 coils 316a, 316b Separated exciting cycle of oscillation after phase synchronizes, and has identical polarity（Such as S poles）With the magnetic pole of same intensity, alternating switch polarity Situation.So as to which the rotary speed of rotor persistently rises the rotary driving force of mechanical load and coil until rotor（Torsion） Mutually until balance, the velocity-stabilization of the node rotor of balance is reached in the two.Cycle of oscillation at this time is to consider electrodynamic type What the usual travel speed of train toy 100 was set.

In this example, since 2 coils 316a, 316b being set on bridge current access 58 are to be electrically connected in series mutually It, therefore, the reciprocal cross induced on 2 scroll coils 316a, 316b is for mutually superimposed, by from the rotation for also comparing low speed Turn to start, induce larger counter electromotive force so that realize the low speed rotation shape from auto-excitation type cycle of oscillation earlier upon actuation Switching of the state to the high speed rotation state of separated exciting cycle of oscillation, can improve starting characteristic.

4th, about battery case

Secondly, referring especially to Fig. 2, the configuration of battery case 4 is illustrated.Driving unit 3 involved by the utility model Shell 34 be formed as front-rear direction with length（L）, left and right directions have width（W）And vertical direction has height（H） Cuboid, particularly, length（L）And width（W）Aspect, compared with previous cell enclosure, it is particularly possible to form to obtain smaller.

Its main cause is following 2 points as described above.1）Motor employs following basic structure, i.e., with small First imaginary plane of gap face setting（Rotor side plane）With the second imaginary plane（Stator side plane）Upper opposite direction respectively is matched Put flat magnet 315a ~ 315d and flat scroll coil 316a, 316b.2）By 4 driven shafts 321 ~ 324, in trailing wheel The superjacent air space of axle 114 is dispersedly adjacent to configuration with drive shaft 311 in the up-down direction.

As shown in Fig. 2, after the housing 34 of driving unit 3 is contained in the rear portion of interior space, it is ensured that before interior space Portion has larger spare space, and battery case 4 can be accommodated in the spare space.Wherein battery case 4 can be by No. four of 1.5V Dry cell is stored side by side in the form of the interlaced ground of 2 batteries head and the tail.

There is the battery case 4 top to offer the box body 41 of opening and cram the upper opening of the box body 41 Upper cover 42.Wherein, the opening that the top of the box body 41 opens up takes No. four dry cells of 2 section 1.5V for filling.2 section 1.5V tetra- Number dry cell, is electrically connected in series, so as to form the DC power supply 40 of 3.0V.In addition, in figure, reference numeral 43 is that have for switching The pronunciation switch of sound pattern and silent mode.

Using in the existing car body of small-sized DC motor available on the market, motor and train of reduction gears occupy substantially Whole length directions of the interior space, therefore cannot ensure the receiving space of enough dry cells, have no alternative but can only to adopt With the structure for carrying 1 section No. tri- dry cells of 1.5V of receiving reluctantly on motor.In this case, it does not simply fail to ensure for a long time Continuous operation sufficient electric power, moreover, for realizing in recent years gradually popular function of pronunciation, camera function, wireless communication It is also inadequate for the supply voltage of the integral microprocessor such as function, illumination functions, as a result, needing DC/DC converters are separately set, and supply is to microprocessor after suitably boosting to the 1.5V voltages obtained from battery, so as to make The consumption for obtaining battery is further speeded up.

In this regard, in the utility model, the direct current of 3V can be directly obtained at battery case 4, and do not need to pass through DC/DC Converter boosts, and it is hereby ensured that sufficient electric power so as to fulfill continuously driving for a long time.Alternatively, it is also possible to realize The gradually integral miniature processing such as function of pronunciation, camera function, wireless communication function, illumination functions of prevalence in recent years The running of the stabilization of device, it is a kind of brand-new electronic so as to by improving the design freedom of this electrodynamic type train, expect The commercialization of formula moving toy.

5th, about loud speaker

Secondly, referring especially to Fig. 2 and Figure 13, the mounting structure of loud speaker 8 is illustrated.At present, referred to as electrodynamic type from In the field of the electrodynamic type toy vehicles of motor-car toy or electrodynamic type train toy etc., prevalence increases function of pronunciation, so as to send out Simulated driving sound or chat voice etc..In the electrodynamic type toy vehicles that vehicle enclosure is made of hull bottom plate and car body cover board In, using there is following loudspeaker installing structure, the flat miniature loudspeaker of function of pronunciation will be used to implement with upward appearance Gesture is installed on the inside top of car body cover board, multiple apertures that the sound which sends out is opened up from top（Sound hole）To vehicle It is spread out of outside body.

In this loudspeaker installing structure that louver is set at top, for focusing on the toy vehicles of aesthetic appearance, The shortcomings of in the presence of appearance and modeling is damaged, simultaneously as will be from loud speaker extraction wire, so as to the vehicle enclosure in battery swap It loads and unloads very inconvenient.

Therefore, for the toy vehicles of emphasis aesthetic appearance, then using another loudspeaker installing structure, pronunciation will be realized The flat cone loudspeaker of function is installed on the inside of the bottom part of hull bottom plate with downward posture, which is sent out The sound gone out is released from multiple sound holes that bottom opens up to track, and the reflection for passing through track is diffused.

Even however, this loudspeaker installing structure, since the characteristic and sound wave reflection characteristic of track are various Various kinds, and the distance between the lower surface of vehicle bottom and track are also different, therefore there are volume deficiency or sound quality Poor the problem of waiting.

In view of this, in the utility model, as shown in Fig. 2 to Figure 13, the flat cone for being used to implement function of pronunciation is raised Sound device 8 is installed on the bottom interior surface of hull bottom plate 11 with downward posture, and the bottom surface of the front-surface side of loud speaker 8 is not provided with Louver, the sound wave sent out by loud speaker 8 make vehicle enclosure 1 voluntarily vibrate, so as to shaking by entire carbody shell 1 Trend outside vehicle releases sound wave.

Specifically, it as shown in figure 13, on the bottom surface of hull bottom plate 11, positioned at the location directly below of battery case 4, is formed There is the circular recess 112 that depth is shallower.The bottom flat of the recess portion 112, and the opening of louver etc. is not provided with without exception.Recess portion Around 112 cricoid ridge 112c is curled into equipped with a lower height of.Therefore, the upper peripheral edge of circular recess portion 112 and ring-type Ridge 112c between be formed with cricoid rank portion 112a, pass through the rank portion 112a support speakers 8.As a result, loud speaker 8 There is gap 112b between the bottom of recess portion 112.

Loud speaker 8 in this example, is flat cone speaker, has, positioned at the flat of speaker body center Circular magnet 8a, winding magnet 8a sound coil 8b and connect and be layed between main body outer peripheral edge with sound coil 8b Vibrating membrane 8c.In figure, based on reference numeral 8d on the spiracle of loud speaker that opens up.

According to this loudspeaker installing structure, by being arranged on the loud speaker of hull bottom plate 11 with downward posture, by Hull bottom plate makes entire vehicle enclosure vibration therefore, louver be opened up with car body top so as to be made a sound to outside vehicle Structure is compared, and will not damage the beauty of car body appearance.With being set to vehicle bottom with downward posture, and put from what bottom plate opened up Sound hole sends out sound, and is compared by the structure that track reflection is diffused, and having will not be because of track Characteristic or with the distance between track etc. and caused by volume or sound quality change the advantages of.

Particularly, in this example, between the loud speaker 8 of downward posture configuration and the bottom surface of bottom plate 11, it is provided with composition The dead air space 112b of resonant chamber, therefore the sound wave released from loud speaker 8 will not decay, and can be effectively transmitted to bottom Plate.And the bottom of circular recess 112 is relatively thin, therefore this structure can also inhibit the attenuation of vibration.

According to the experiment of the inventors of the present invention, Fig. 1 ~ Fig. 3 will be provided with, the train toy 100 of vehicle enclosure shown in fig. 51 is made For outturn sample, in the office environment of volume 40dB or so, the position configuration dB detectors of 10cm, measure in front of car body Caused by boombox 8 during volume, following result is obtained：
