It is set according to such diameter of axle, by forming the diameter of axle of drive shaft 311 and the driven shaft 321,322 of side of first stage For the smaller structure of the driven shaft diameter of axle than rear stage side, ensure swimmingly to rotate starting so as to reduce the friction of bearing, 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 guarantees power transmitting so as to bear rotary load.In addition, the diameter of axle of third driven shaft 323 exists in this example It is the largest among driven shaft, this, which allows for ratchet pawl etc., can apply biggish thrust load.

As shown in figure 8, being equipped with the small of the horizontal gear rotated integrally with axis 311 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 composed by 321b.In addition, be equipped in second driven shaft 322 with axis 322 rotate integrally by large diameter gear 3 horizontal gears composed by 322a, central diameter gear 322b and small-diameter gear 322c.

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 configured adjacently with central diameter gear 323b, and is rotated integrally with axis 323 While can be slided back and forth in predetermined stroke along axis 323.On the other hand, small-diameter gear 323c and 2 gear 323a, 323b is separately positioned, and can be slided in linkage with 2 gears 323a, 323b.Moreover, after small-diameter gear 323c can pass through The clutch stated is combined with axis 323.That is, being rotated integrally when above-mentioned clutch connection with 2 gears 323a, 323b, and work as When 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, rear-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, with disperse in the up-down direction and with drive shaft 311 it is adjacent State whole centralized configuration is in the upper space of axle 114, thus 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, the previous slippages as caused by crown gear like that will not be generated.

About gear displacement mechanism

Hereinafter, being illustrated referring especially to Fig. 6, Fig. 7 and Fig. 8 to gear displacement mechanism.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 stick 33）First operation（Slide between OFF position and the position ON）, by by particular gear（Gear 323c） It is displaced in axial direction, makes particular gear and adjacent gear（324a）Between be intermeshed 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 stick 33）Second operation（Slide between the position ON and the position HI）, by will be specific Gear（Some in 2 gears 323a, 323b）It is displaced in axial direction, makes particular gear and other gear（Gear Some in 322b, 322c）Intermeshing, so as to change the rotation that the drive shaft 311 of the rotor is transmitted to axle 114 The reduction ratio of power.

Specifically, above-mentioned first gear displacement mechanism and second gear displacement mechanism pass through specific displacement operation machine Structure is operated.The displacement operation mechanism includes operating stick 33, lobe plate 33a, cam follower 33b.Wherein, operating stick 33, End is prominent and vertical with shell to outside shell from guiding slot 121 thereon.Lobe plate 33a, the lower end with operating stick 33 Connection, and be supported on car body front-rear direction freely slidablely with horizontal posture, and have in its side edge 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 Text）" font and clamp 2 gears 323a, 323b clamping part 33b, and have 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, thus 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 insertion for cam follower 33b Groove.Meanwhile cam follower 33b is pressed by compressed spring 33e, is pushed into the side edge cam 33g.

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

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

About direction of rotation limiting unit

Secondly, being illustrated referring especially to Fig. 5 to reversed limiting unit is rotated.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 that electrodynamic type be made to arrange The car body of Toy vehicle is advanced forwards.

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

However, according to the increase of connection vehicle number or carrying out climbing walking etc. in this electrodynamic type train toy When it is travelled load the case where will increase, and in view of child's hand push pushes traveling（That is manual operation）Deng situation, less It is easy 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 sets.

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, 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, the direction of rotation for the large diameter gear 321a that ratchet pawl 325a is used to install 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, 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, 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 stick 33（OFF position, the position ON, the position HI） The meshing state of corresponding train of reduction gears be illustrated.

As described above, when operating stick 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.Rear-wheel 114a, 114b of left and right are free state as a result, and electric motor 31 is logical 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 push traveling to play with hand push.

When operating stick 33 is located at the position ON, such as Figure 11（a）It is shown, pass through connecing for edge cam 33g and protruding portion 33f Touching, 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 rear-wheel, It is possible thereby to travel electrodynamic type train toy 100 with usual speed.

When operating stick 33 is located at the position HI, such as Figure 12（a）It is shown, pass through connecing for edge cam 33g and protruding portion 33f Touching, cam follower 33b since the active force of compressed spring is pushed back terminal location, thus, 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 rear-wheel Transmitting, it is possible thereby to make electrodynamic type train toy 100 to be carried out at high speed traveling.

About clutch configuration

Hereinafter, being illustrated referring especially to Fig. 7 to clutch configuration.In second gear displacement mechanism illustrated before It is provided with spring 323d, 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, being provided with the chimera 323e with non-linear symmetric profile 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 state from OFF state, firstly, the freedom that gear 323c is not fitted into chimera 323e State is abutted against with gear 324a phase, then, is resisted two gears under reaction force state and is gradually engaged, finally, chimeric Part 323e is embedded in the state of embedded hole, and 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, handing over conversion circuit 5 to be illustrated to straight referring especially to Figure 17.As shown in figure 17, this directly hands over conversion circuit Portion is constituted 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 box 4（3V）Driving.

That is, the straight friendship conversion circuit, includes：Driving transistor 51a, the 51b in left side, 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；Pull down resistor 54a, the 54b in left side, right side；And between electrostatic capacitance 56a, 56b and resistance 55b, 55a Series circuit.Driving transistor 51a, the 51b in the left side, 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 respectively with left side, right side driving with transistor 51a, 51b, and pass through left side, the right side Control is opened and closed with the output of the driving of the opposite side in transistor 51a, 51b transistor in side driving.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 Side out（Collector）Between.Described 1 or 2 or more（It is 2 in this example）Scroll coil 316a, 316b, make Load cell for driving transistor 51a, the 51b in left side, right side is arranged in the bridge current access 58.The left side Side, right side pull down resistor 54a, 54b, by the control terminal current potential of the driving transistor in left side, 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 is respectively arranged at the control terminal of the driving transistor 51a in left side for setting auto-excitation type cycle of oscillation Son（Base terminal）The output 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 output 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.

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

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 the resistance 57 for promoting starting side by side.

By above structure, after power switch 33a is connected, by the effect for promoting the resistance 57 of starting, make a left side The driving unlatching 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 that 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 direct capacitance magnitude and resistance of the resistance value of pull-down resistance 55a, 55b of left and right and capacitor 56a, 56b 55a, 55b are come auto-excitation type cycle of oscillation for determining（Defined long period）, it is alternately carried out opening and closing.The auto-excitation type cycle of oscillation sets It is fixed, it is to be set on the basis of consideration is actuated for induction to the rotation of rotor.

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

It is now assumed that the state of Fig. 4（Permanent magnet 313a, 313c are the pole N, and permanent magnet 313b, 313d are the pole S）In, If being the pole S by coil 316a, 316b excitation, permanent magnet 313b, 313d of the pole S are upper to have repulsive force with regard to effect, meanwhile, Acted on permanent magnet 313a, 313c of the pole N it is attractive, thus on rotor just generate diagram clockwise rotary driving force （Torsion）.In addition, rotor is the permitted direction of rotation ratchet pawl 325a clockwise.At this point, rotor clockwise after It is continuous be rotated by 90 ° after, when coil 316a, 316b are excited as the pole N, effect has row on permanent magnet 313a, 313c of the pole N Repulsion, meanwhile, acted on permanent magnet 313b, 313d of the pole S it is attractive, thus on rotor just generate diagram it is clockwise Rotary driving force.By being iteratively produced such state, after rotor clockwise starting, speed is gradually increased.In addition, due to synchronization Direction of rotation is uncertain when the starting 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 obtaining clockwise rotary torsion, above operation can be realized, motor just rotates clockwise starting.

When the rotation speed of rotor reaches specified value, pass through on coil 316a, 316b in permanent magnet 313a ~ 313d Time point（That is, the opportunity of permanent magnet and scroll interleaving coils）, the counter electromotive force arteries and veins that is incuded on coil 316a, 316b The size of punching increases, and the driving of left and right in this way is in is opened at that time in transistor 51a, 51b（ON）The base of the transistor of state Electrode potential moment gets a promotion（Reverse bias）, thus 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, with before the case where it is identical, successively via the driving transistor 51a → bridge current access in left side The driven power-on circuit with transistor 52b on 58 → right side, and successively via the driving transistor 51b → bridge current on right side The driven power-on circuit with transistor 52a in 58 → left side of access is alternatively formed, thus to 2 coils with identical the number of turns 316a, 316b, with identical current value, alternately to first direction（In figure, from left to right）Be powered and to second direction （In figure, from right to left）It is powered, to occur and be synchronized with every half revolution of rotor on 2 coils 316a, 316b Separated exciting cycle of oscillation after phase is synchronous, polarity having the same（Such as the pole S）With the magnetic pole of same intensity, alternating switch polarity The case where.To which the rotation speed of rotor persistently rises the rotary driving force of mechanical load and coil until rotor（Torsion） Mutually until balance, reach the velocity-stabilization of the node rotor of balance 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 , 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, biggish counter electromotive force is induced, so that realizing the low speed rotation shape from auto-excitation type cycle of oscillation earlier after actuation High speed rotation state from state to separated exciting cycle of oscillation switching, starting characteristic can be improved.

4, about battery case

Secondly, being illustrated referring especially to Fig. 2 to the configuration of battery case 4.Driving unit 3 involved in 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, in particular, length（L）And width（W）Aspect, compared with previous cell enclosure, it is particularly possible to be formed smaller.

Its main cause is following two points as described above.1）Motor uses 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 Set flat magnet 315a ~ 315d and flat scroll coil 316a, 316b.2）By 4 driven shafts 321 ~ 324, in rear-wheel The upper 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 shell 34 of driving unit 3 is contained in the rear portion of interior space, it is ensured that before interior space Portion has biggish spare space, can accommodate battery case 4 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 is for filling No. four dry cells for taking 2 section 1.5V.2 section 1.5V tetra- Number dry cell, is electrically connected in series, to form the DC power supply 40 of 3.0V.In addition, appended drawing reference 43 is that have for switching in figure The pronunciation of sound pattern and silent mode switchs.

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 accommodating space of enough dry cells, have no alternative but can only to adopt With the structure for carrying 1 No. tri- dry cells of section 1.5V of receiving reluctantly on motor.In this case, it is not only unable 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 for the supply voltage of the integral microprocessor such as function, illumination functions and inadequate, as a result, needing DC/DC converter is separately set, and supply is to microprocessor after suitably boosting to the 1.5V voltage obtained from battery, 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 from battery case 4, and do not need to pass through DC/DC Converter boosts, and it is hereby ensured that sufficient electric power to continuously drive for a long time to realize.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 stable running of device can be expected a kind of brand-new electronic thus by the design freedom for improving this electrodynamic type train The commercialization of formula moving toy.

5, about loudspeaker

Secondly, being illustrated referring especially to Fig. 2 and Figure 13 to the mounting structure of loudspeaker 8.Currently, 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, to issue 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, i.e., by the flat miniature loudspeaker for realizing function of pronunciation with upward appearance Gesture is installed on the inside top of car body cover board, multiple apertures that the sound which issues is opened up from top（Sound hole）To vehicle Outflow outside body.

It is this top setting louver loudspeaker installing structure in, for focus on aesthetic appearance toy vehicles for, The disadvantages of in the presence of appearance and modeling is damaged, simultaneously as will be from loudspeaker extraction wire, thus the vehicle enclosure in battery swap It loads and unloads very inconvenient.

Therefore, realization is pronounced then using another loudspeaker installing structure for focusing on the toy vehicles of aesthetic appearance 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 Multiple sound holes that sound out is opened up from bottom are released to track, and are diffused by the reflection of track.

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 It is poor

In view of this, as shown in Fig. 2 to Figure 13, will be raised in the utility model for realizing the flat cone of function of pronunciation 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 loudspeaker 8 is not provided with Louver, the sound wave issued by loudspeaker 8 vibrate vehicle enclosure 1 voluntarily, to pass through the vibration of entire carbody shell 1 Trend outside vehicle releases sound wave.

Specifically, as shown in figure 13, on the bottom surface of hull bottom plate 11, positioned at the following location directly of battery case 4, being 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 Cricoid ridge 112c is curled into equipped with a lower height of around 112.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 speaker 8.As a result, loudspeaker 8 There is gap 112b between the bottom of recess portion 112.

Loudspeaker 8 is flat cone speaker, has, positioned at the flat of speaker body center in this example Circular magnet 8a, wind 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 appended drawing reference 8d on the spiracle of loudspeaker that opens up.

According to this loudspeaker installing structure, by the way that the loudspeaker of hull bottom plate 11 is arranged in downward posture, by Hull bottom plate makes entire vehicle enclosure vibration to make a sound to outside vehicle, therefore, opens up louver with car body top Structure is compared, and the beauty of car body appearance will not be damaged.It is set to vehicle bottom with downward posture, and what is opened up from bottom plate puts 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.

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

The experiment of people etc. according to the present invention will be provided with Fig. 1 ~ Fig. 3, the train toy 100 of vehicle enclosure shown in fig. 51 is made For product sample, in the office environment of volume 40dB or so, the position of 10cm configures dB detector, measurement in front of car body When volume caused by boombox 8, following result is obtained：

Condition 1：Volume measurement when carbody shell 12 is installed on hull bottom plate 11：

1）Loudspeaker downwards+be equipped with louver：55~60dB；

2）Downward+not set louver of loudspeaker：63~70dB；

Condition 2：Volume measurement when carbody shell 12 is unloaded from hull bottom plate 11：
