The display screen is substantially vertical during normal viewing. These doors have loudspeakers on their interior surfaces, which doors open out from the sides of the cabinet to space the loudspeakers further apart for better stereophonic sound reproduction. Console for hutch types of cabinets for television receivers can also employ hinge-pin portions for swinging the doors over the display screen.

Description

Display band door, door comprise the television receiver of loud speaker again

The present invention relates to have the television receiver of band door display screen, more particularly, relate to a kind of like this television receiver, on its door, loud speaker is arranged.

The special portable television receiver that adapts to young consumer market is a kind of conception (concept) of present inventors, and this television receiver is enough little and enough gently, and being easy to is that ten next years old children carry, and is suitable for playing video game.In order to remove the weight of battery pack, though this television receiver light to connect the power supply power supply usually.A kind of portable computer monitor is particularly suitable for young consumer market, and this computer monitor is enough little and enough gently, and being easy to is that ten next years old children carry, and is suitable for playing video game, and this is present inventors' a relevant conception.In this manual, this television set or computer monitor are known as " children are portable ".When the thought of children was upset by the hope of playing video game, they can not add littlely this " children are portable " television set or computer monitor are moved continually.Therefore, consider the protective cover of display screen, to reduce in this handling process possibility (and the injury to children that may cause thus) that picture tube or liquid crystal indicator is caused damage.

Have again, it is with gemel being used to close the two-door of display screen, be beneficial to constitute " children are portable " portable television receiver, allow children to carry receiver in the both hands mode of carrying, and make the two-door bottom of closing that leans against the body front with the handle of the cabinet left and right sides.Be in particular American Youth consumer market design and portable television receiver that be used for playing video game comprises a chassis base, one is rotated and leaning device, it not only helps regulating the direct-view direction adapting to watching of people, but also helps regulating the stereo music direction that loud speaker outwards sends from two-door to adapt to people's the sense of hearing.

The United States Patent (USP) of authorizing Finley Ruppersburg on December 14th, 1971 is entitled as " stereophonic reproduction system " 3,627, No. 392.The portable stereo reproduction means that Ruppersburg describes has a cabinet, has left hand revolving door and the right hand revolving door opened to disconnected position from cabinet the place ahead on the cabinet.When opening to disconnected position, the loud speaker that is contained in the door is arranged as stereo orientation when two-door.The phonograph that rotates is housed in the cabinet and has corresponding playback electronic installation.

The rotation cabinet that portable television receiver and computer monitor have used is beneficial to regulate positive apparent direction.The United States Patent (USP) that is entitled as " whirligig of television receiver " of authorizing Takashi Nodama on September 7th, 1993 is the proof of this fact for 5,243, No. 434.Jeong-Seop Lee that on July 22nd, 1992 announced and UK Patent Application GB 2252 003A of Woo-Jin Kim are entitled as " turntable of television receiver ", the positive apparent direction that the turntable that uses motor driven is regulated television receiver has been described, this television receiver has loud speaker, be included in the box body that picture tube is housed, be positioned at the picture tube display screen about.

The large floor formula bearing in past and box television receiver have utilized door to cover its display screen when turning off receiver; The main purpose of using door is in order to beautify the environment, thereby does not allow the people see " dead eye " (the dead eye) of no-raster picture tube.The popular cabinet that changes forward of a period of time eurovision receiver, the door that changes forward accounts for less space when opening.In stereophonic sound system, also use door as decorating.The United States Patent (USP) 5 that is entitled as " the stereophonic sound system cabinet of band loud speaker door assembly " in issue on June 2nd, 1992,119, in No. 421, Reime has described a stereophonic sound system cabinet, the Speaker panel of opening before having, it can rotate around vertical axis, and Speaker panel is not closed as door when the cabinet of stereophonic sound system does not use.Loud speaker is contained in the bottom of door, covers a support at an upper portion thereof, can be used to hold " desk-top " color TV set; So influencing the problem of color TV set colour purity, the permanent magnet of speaker motor do not consider.So machine box door is being opened mostly in most of families, only missionary or other VIPs even visit and just shut machine box door.The expense (particularly with thin wood lining time) of this trend of seldom closing the door and door has been dwindled the market that the band door is covered the television receiver of display screen.Make revolving door enough high resembling that Reime does, can make Men Gengchong and be easier to and distort with cover respectively on TV display screen and loud speaker.

Have again, as described previously leftward with right hand revolving door in the stereo reproduction means of boombox is housed a problem be to make the surface that the box body motion may rose engine casing place in order to make the direction that stereo sensing hearer wishes.Under the situation of floor pedestal or box cabinet, they may be quite heavy, and mobile box body can be delineated hardwood flooring, lino or the linseed oil floor tile floor of supporting box body.Under the situation of portable stereo reproduction means, rotate box body for the direction that stereo sensing hearer is wished and to delineate the desktop of supporting box body.Although the weight of portable stereo reproduction means less than the stereo reproduction means in floor pedestal or the box cabinet, supports the desk of portable stereo reproduction means box body to have meticulous furniture surface, it is easier to be scratched than hardwood flooring.

Realizing portable television receiver of the present invention or calculating in the monitor that door is not the purpose that is used to beautify.On the contrary, design gate is for they can be carried by children, and mainly is for the possibility (and injury to children of reducing may cause) of protection display screen to reduce to damage picture tube or liquid crystal indicator in the process of carrying.Even hinged door that door is opened before being rather than rotary door forward, but these reduced size makes them so heavy.A left side and the door of turning right can be closed display screen and boombox is included in the door, and when left and right revolving door reached the position that is separated from each other, boombox was in the side of display screen, rather than are positioned at the below of television receiver display screen.

Some television broadcastings and some video-games provide stereo, the loud speaker of portable television receiver is got enough opened to reach directed sound reproduction, and this is a problem.With cable satellite speaker is linked on the portable television receiver and can be overcome this problem.Yet satellite speaker influences existing portability, lose when being easy to be carried by children, and can be because children's game increases family's deposit.Boombox is contained in the door of opening to about display screen, make the loud speaker degree of separation be enough to realize direct sound regeneration near the children that are sitting in the portable television receiver, for little for the small size display screen that receiver had that can be carried by children, near being normal.The door that adds hinge comprise add hinge left-hand door when closing from cabinet rotate with cover display screen left hand one side and when opening from the left hand one side expansion of cabinet; also comprise add hinge right door when closing from cabinet rotate with cover the display screen right hand one side and when opening from the right hand one side expansion of cabinet, this is not only protection picture tube and liquid crystal indicator when moving.In the process of moving, this door has also been protected the loud speaker of the inside that is contained in door when closing display screen.

In the United States Patent (USP) that is entitled as " stereo reproduction means " 2,547,447 of issue on April 3 nineteen fifty-one, de Boer has described boombox has been contained on the left and right sliding door of stereo radio electricity receiver.In the device of de Boer, loud speaker is dressed up the outside of the left and right slide of its opening when slide cuts out radio receiver, and this makes loud speaker can not get suitable protection in the process of moving.For example, between storm period when a building is moved another building to, water is easy to enter speaker openings.The inboard that loud speaker is contained in the chain chain door of cutting out display screen can prevent the generation of this incident, because the cabinet of portable television receiver of children or computer monitor and door are normally made by fluid-tight engineering plastics.

Loud speaker is contained in the door that covers the television receiver display screen when moving, this relates to some considerations that de Boer or Reime had not run into, these considerations are relevant with the interaction in the magnetic field that the loud speaker magnetic element of close display screen when door is closed display screen is sent, and will point out here.For example, the permanent magnet in the speaker drive motor distorts near the magnetic state the picture tube front panel.Near the display screen hardware is magnetized, and causes local magnetic field, and this influences electron beam and drops on image on the display screen fluorophor, causes the colour purity problem.

As the designers of color TV set are known, shadow mask (shadow mask) in the picture tube or aperture grid are normally made by ferromagnetic metal, thereby among it is exposed to magnetic field the time, even the low-intensity magnetic field resemble the magnetic field of the earth also can be magnetized.This magnetized any variation, as the sort of change that is taken place in the television receiver process that the position changes in the magnetic field of the earth, the capital influences the deflection (these three electron beams scan red radiofluorescence body, green radiation fluorophor and the blue radiofluorescence body in the display screen respectively) of three electron beams, cause losing suitable joining property of colour, this is unacceptable fully to the beholder.In order to tackle the loss of this joining property of colour and to keep colour purity, chromoscope has built in degausing coil usually, and when starting shooting first after television receiver is turned off a period of time, anti-magnetized coil is just to baffle or the quick demagnetization of aperture grid.Yet, as noted here, if before the door on the display screen is opened and pinned or remains on open position, receiver is switched on, just can disturb the autodegauss coil to remove because near the magnetic field display screen that the loud speaker radiation field induces is unusual.Therefore, if the chromoscope that uses aperture grid chromoscope, baffle chromoscope or relevant type in portable television receiver of children or computer monitor is as display unit, and in closing the hinge side door of display screen, be equipped with loud speaker, it is to be noted that so here autodegauss should delay door and open and pin or keep carrying out after its open position again.Can do like this, be deferred to promptly that door is opened and negative live or remain on open position after again television receiver or computer monitor are powered up again.

Can otherwise get rid of or avoid owing in closing the hinged door of display screen, comprising the colour purity problem that loud speaker causes.If adopt aperture grid chromoscope, baffle chromoscope or correlation type chromoscope, in aperture grid or baffle, casing and picture tube support, use nonmagnetic substance can reduce the colour purity problem as display unit.In any case for weight reduction with resist the damage that leaves or collide and cause with other objects because of accidental, it is attractive adopting engineering plastics in portable television receiver of children or computer monitor.The formation of speaker motor can be avoided using the permanent magnetization structure, but adopts electromagnetic structure fully.Really, in the door motor of loud speaker can be electrostatic rather than electromagnetic type, can avoid magnetic texure better.Because having the good small-sized electrostatic loudspeaker than LF-response is a problem, so the loud speaker in door can be assisted with a LF-response electromagnetic type loud speaker conduct, this loud speaker can be arranged in chassis body or in its substrate.For avoiding the colour purity problem, can replace another kind of colour display device, for example liquid crystal colour disply without the chromoscope of standard, or use single rifle picture tube of controlled penetrability fluorophor, it can be called " green onion skin (onionskin) " type picture tube.Yet, preferably use traditional chromoscope, because its price is lower.

It is very attractive that the boombox that adopts in being particularly suitable for the portable television receiver of youth market is placed on the conception that shows in the screen door, so that this conception expands to all kinds of color TV sets on the American market, comprise the console receiver on non-portable desktop receiver and the floor.This conception also will be used for computer monitor.Other local television receiver styles of the style of U.S.'s television receiver and the world are different.Other places in the world, particularly in Europe, popular is that kinescope screen is embedded in the cabinet with flushing, and the television receiver of the U.S. and computer monitor make its kinescope screen be contained in the back of cabinet costa colpi usually, for the beholder forms a menu frame, this is that U.S. consumer has a preference for.

The picture tube that the portable television receiver that is in particular American Youth market and designs for playing video game uses has flat front surface, dark costa colpi is arranged on every side, so that reducing incident light when playing on the daytime drops on the panel, and children are felt as him in the world of oneself, be not subjected to adult invasion.Before the putting on market of possible cabinet design, in the pre-research, when estimating the design of zanjon edge, be another factor that will consider because the baffle of picture tube or aperture grid are magnetized may being offset of being caused by loud speaker permanent magnet in the door.The portable television electric drive picture tube of having produced is just taked traditional demagnetization measure when switching on for the first time after television receiver is turned off a period of time, this has been used for the zanjon edge design television receiver that the pilot uses.

Surprisingly, during the zanjon edge design television receiver work used as this pilot, do not have evidence to show the problem that has expection, promptly the baffle of picture tube or aperture grid had been done explanation by the magnetized problem of loud speaker permanent magnet in the door hereinbefore to the solution of this problem.In retrospect, it seems that this be owing to having adopted high-permeability material to add the magnetic texure that is adopted for keeping motor weight to descend, having made that the magnetic flux bleed-through of modern speaker motor is quite little.The road of loud speaker when panel rotates is through being that path Yuan Lu when opening by door returns, so the changes of magnetic field that causes goes to zero.Use the design of costa colpi and door that the surface of a permanent magnet of dress loud speaker and kinescope screen is kept at a distance of several centimetres, thereby avoided picture tube baffle or aperture grid to be magnetized to the problem that is enough to the appreciable impact colour purity.

Have, the television receiver of pilot's zanjon edge design uses monophony low-frequency range loud speaker, or " bass horn (woofer) " again, and it is contained in the television reception machine enclosure and leaves kinescope screen somewhere.The mankind realize that the stereo separation effect mainly is at Mid Frequency, particularly when the loud speaker spacing all the more so during less than the 4-5 foot.Because not obvious in the stereo separation effect of low-frequency range, so adopt the monophony bass horn usually in more cheap stereophonic reproduction system when the loud speaker spacing is limited in less than the 4-5 foot, particularly those floor stand cabinet type systems are all the more so.In order to keep the acoustical coupling in low-frequency range and room, hearer place, bass horn is bigger than the surface of tweeter by the surface of its motor driven (taper surface).In order to make bass horn can drive these big surfaces, the size of the permanent magnet in the motor of bass horn and magnetic field intensity all (or claim permanent magnet in the motor of " loudspeaker " greater than the motor of mid frequency ludspeaker and some type tweeter.Not loweing in the door of the television receiver that pilot's zanjon edge designs, the sound loudspeaker help avoid the picture tube baffle or the aperture grid is magnetized to the problem that is enough to the appreciable impact colour purity.This allows the costa colpi degree of depth in zanjon edge design television receiver can do more shallowly, and don't suffers because picture tube is caused the colour purity loss by the speaker motor magnetization.

When design children's portability television receiver or computer monitor, also consider other factors.Move for cabinet weight being reduced be beneficial to children, used not design with the 50/60Hz power transformer.Except the hinged door of cabinet, cabinet surrounds that part of equipment that is used for producing image on display screen fully, and does not allow to cause the object of electric shock disaster to insert in the casing.The cabinet preferred design becomes to encourage children with the hands to move, and shows the belly of screen door facing to children with it.This has reduced the chance that is linked to be injury when mentioning, and has also reduced the equipment that leaves or has made cabinet and the possibility of other people or object collision.If handle is provided, preferably be placed on cabinet both sides or cabinet below, carry it not encourage children's one hand.When closing, be designed to have the round corner of long radius for cabinet that children moved, with reduce children damage oneself, furniture in the vestibule in other children, house or wall, the room or the possibility of vehicle.Consider if can satisfy price, be preferably in and have surface soft or the band cushion on the cabinet.The hinge of machine box door and door lock mechanism will be designed to avoid clamping the possibility of finger or other parts of health.The hinge of machine box door will have firm structure, and machine box door can not be twisted from cabinet.If hinge uses hinge pin (for example piano type), the two ends of each hinge will provide protection, pulled out by children to stop hinge pin.Electric drive signal should be made to the conduction of loud speaker and make lead be difficult for being made a mess of by children.Moving in the process feed cable at the portable television receiver of children or computer monitor preferably can go back in the cabinet.Can comprise that in portable television receiver of children or computer monitor a device can play out in advance " dialling plug down " information of record, when children are activated receiver or monitor this device when resting position is mentioned.The device of this play cuing information can be similar to the sort of device that uses in some toys (as sociable rag baby).

One aspect of the present invention is to realize portable television receiver of a kind of children or computer monitor, and it has an energy to cover its display screen in the process of moving.Boombox is housed in door, and door is opened to about display screen, makes the distance of separation of loud speaker make life be enough to obtain directivity sound reproduction effect near portable television receiver children nearby.If provide demonstration by picture tube, then this picture tube is closely to watch safe low radiation type picture tube to this.

In the portable television receiver of a use chromoscope or computer monitor, there is Men Zaiqi to move to cover its screen in the process and shows screen, in the door that has boombox to be contained in to about display screen, to open, in such portable television receiver or computer monitor, another aspect of the present invention is that the autodegauss process is postponed till the door that covers display screen and opened and pin or stay separately and carry out after the open position.It is unusual that this helps proofreading and correct before near the remnant field display screen that the magnetic field induction by the loud speaker radiation comes out.

Portable television receiver of Gou Chenging or computer monitor use liquid crystal colour disply and do not adopt chromoscope according to a further aspect in the invention, it has door to cover display screen in the process of moving, in the door that has loud speaker to be contained in to open to about display screen.Door close cover display screen during, liquid crystal colour disply is not subjected to the influence in any magnetic field of loud speaker radiation.

Television receiver of Gou Chenging or computer monitor have a chromoscope according to another aspect of the present invention, it can lose colour purity because of changes of magnetic field, a costa colpi frame is centered around around the picture tube display screen, left and right two-door its display screen and the costa colpi frame on every side of covering, left and right loud speaker is contained in the inner surface of its left and right door, and speaker motor has permanent magnet.The door of outwards opening from the cabinet both sides spatially further separates loud speaker, causes better stereophonic reproduction effect.The motor of loud speaker comprises permanent magnet element separately.Loud speaker is contained in the door, and the costa colpi frame makes display screen surface recessed inwards from the cabinet front side, this physical dimension makes the permanent magnet element of speaker motor and display screen surface keep several centimetres distance, thereby can the permanent magnet element of speaker motor does not cause tangible colour purity lose owing to show changes of magnetic field near display screen surface when door is opened owing to closing behind the door.

Portable television receiver of Gou Chenging or computer monitor have door to cover display screen in the process of moving according to a further aspect in the invention, and having boombox to be contained in the left and right door of opening of display screen, the structure of its boombox makes wherein not by the permanent magnetization element.

Have again, box body is supported on a base or the support, do not need movable base or support, thereby solved the problem that surface that box body places is delineated in order to make the different direction of stereo sensing.Box body is supported on base or the support, and box body can easily rotate with respect to base or support when hope makes the different direction of stereo sensing.

Figure 14 is the schematic diagram of an alternative embodiment of the invention.

The portable television receiver of children has a cabinet 10 as shown in Figure 1, and is in light weight owing to being collided and wish, so cabinet 10 is preferably made by engineering plastics.This engineering plastics should be fluid-tight.Shown in cabinet 20 be placed in rotatable and the bearing 11 that tilts on.The display screen 12 of display unit is equipped with in the front side of cabinet 10, and the display unit of 33 centimetres of picture tubes of diameter of low radiation for example is housed.The left-hand door 13 that is in fully open position shown in the figure has high-frequency horn, Low frequency horn and mid frequency ludspeaker 14,15,16 to be contained in the door, thereby they are outwards sounded from the inner surface of the exposure of door.The right door 17 that is in fully open position shown in the figure has high-frequency horn, Low frequency horn and mid frequency ludspeaker 18,19,20 to be contained in the door, thereby they are outwards sounded from the inner surface of the exposure of door.

Bead among Fig. 1 in the hole of an insertion of supposition left-hand door 13 usefulness cabinet 10 is hinged on the cabinet 10, supposes that right door 17 also is hinged on the cabinet 10 similarly, and this hinge arrangement is called " relative pin and eye ".Yet other hinge arrangements such as strong piano hinge also can adopt.If can find a kind of flexible engineering plastics, it still has enough intensity after repeated deformation, and this hinge can be realized by folding plastic itself.

Door 13 and 17 bead end are as the hinge pin in relative pin and the eye hinge arrangement, and be porose in bead, but cannot see in Fig. 1.Be used for the electric lead that the signal of performance sound sends left-hand door 13 loud speakers 14,15,16 to from the left audio frequency amplifier of television receiver is passed one or several this hole of bead end the left-hand door 13; Be used for the electric lead that the signal of performance sound sends right door 17 loud speakers 18,19,20 to from the right audio frequency amplifier of television receiver is passed one or several this hole of bead end the right door 17.The another kind of practice is, can realize electrical wiring by the armoured cable that connects cabinet 10 and door 13 and 17 respectively, leave the space in door 13 and 17, with at the two-door armoured cable that holds when closing display screen 12.

Quite the costa colpi frame 21 of the degree of depth surrounds display screen 12, to accept the loudspeaker of woofer 15 and 19.Costa colpi frame 21 constitutes the previous section of cabinet 10, and door 13 and 17 hinges are on it.Round angle is arranged for costa colpi frame 21 and door 13 and 17 in case the children of television set are carried in injury or the children on television set of falling.Make the costa colpi frame have sizable degree of depth can protect display screen 12 to be knocked better, and the costa colpi frame is strengthened as structure member so as not to accidental.Fig. 1 demonstrate be used for main television control fall in shake key, they are positioned at the opening of costa colpi frame 21, what comprise switch television receiver power supply shakes key 22, control wave volume height shake key 23, what the control channel was selected up and down shakes key 24, and select to television receiver provide radio frequency signals signal source shake key 25 (control uses television receiver to make the power supply of electronic game machine in some designs).Perhaps, these shake operating key 22,23,24 and 25 and can be arranged in a inside groove on costa colpi frame 21 front surfaces.On the front surface of costa colpi frame 21, there is one one to be used for hiding the operating key be of little use, as the high pitch and the bass control of audio frequency by the panel 26 of promptly opening (snap-open).Be used to receive the front surface that also is positioned at costa colpi frame 21 from the infrared sensor 27 of the remote signal of Infrared remote controller 28.The key that the whole television set functions of control are arranged on the Infrared remote controller 28.

As shown in Figure 1, a spring bolt 82 can be contained in top center the place ahead of costa colpi frame 21, is used to fasten close door socket 83 at 13 and 17 inner surface tops and 87 edge, moves being used to so that fix the door 13 and 17 of closing definitely.Button 84 in costa colpi frame 21 central term surfaces is pressed and then decontrols door 13 and 17. Stage clip 85 and 86 are arranged closing door 13 and 17 inner surface top, thereby be depressed when decontroling spring bolt 82 when button 84, stage clip 85 and 86 flick door 13 and 17.These stage clips 85 and 86 can be the elastoplast blades, and may constitute these two stage clips in door 13 and 17 inside plasticity panels itself.Perhaps, stage clip 85 and 86 can be positioned at the front surface top of costa colpi frame 21.Also can use other safety latch structures to fix door 13 and 17, the injury children but they should avoid outstanding structure, the possibility that they should avoid children to be held under the arm into, they should be reasonably simply to adapt to children's operation.

Fig. 2 demonstrates the rear portion of children's portability television receiver shown in Figure 1.Engineering plastics bonnet 29 constitutes the rear portion of cabinets 10, links to each other with costa colpi frame 21 and fixes with screw 30.The engineering plastics that constitute costa colpi frame 21 and bonnet 29 are electrical insulators, and permission is used transformerless power supply and do not had significant electric shock disaster in television receiver.Screw has the groove (for example groove of those screws of fixed car headlight) of hourglass shape or other special shapes, to give up the thought that children will separate bonnet 29 and costa colpi frame 21, adopts anti-liquid sealing glue outside the connection between bonnet and costa colpi frame.Bonnet 29 corners are circular, carry television set or the children's on television set that fall possibility to reduce injury.Preferably bonnet 29 does not have enterable hole, attempts object is thrown in possibility in the receiver electronic unit to reduce children, reduces liquid yet and sprinkles possibility into television receiver.Have again, receiver is taken out of not conference of open air cause problem at rain or snow weather.Bonnet 29 is can be on its bottom surface porose to be used for the insertion instrument sheltering adjusting etc., thereby can only could insert television receiver after rotation and inclination bearing 11 unload.If vent must be arranged near the top of cabinet 10 to allow the heat that produces in the television receiver get rid of, preferably allow these holes be positioned at the front surface of costa colpi frame, these holes can be moved in the process by door 13 and 17 at receiver and be closed there, and to be still reality feasible so at rain or snow weather receiver is taken the open air.

Different with other portable television receivers is that receiver shown in Figure 1 is not with the handle that is positioned at the top.Doing like this is to move with hand again in the time of will encouraging children to move receiver, and the door of closing with receiver heads on his belly, because this position of moving believes that can to attempt to carry the risk of injury that receiver brings with the handle that is positioned at the top than him little.The structure of rotation and inclination bearing 11 makes it not influence this both hands and moves, and the center of gravity of receiver is positioned at receiver the place ahead slightly, and can there be shallow slot the bottom of bonnet 29 along its left and right sides so that finger is held receiver.Shown in power line 31 guide into be contained in the rotation and inclination bearing 11 in the spring bobbin winoler on, this has limited rotation amount.The another kind of practice is: the spring bobbin winoler is placed among the bottom of bonnet 29, but this has reduced the space of electronic unit of packing in bonnet 29, and makes not that easy use of bobbin winoler.Have, bobbin winoler must be opened in the container with receiver electronic unit branch again, and this makes bonnet 29 complicated as the individual unit casting.Comprise bobbin winoler and cause the minimizing of placing the electronic unit space in bonnet 29, this situation for computer more merits attention.Be arranged in the design of the front portion of receiver or computer in the control of the power supply of electronic game, on the rear board part of bonnet 29, provide power connection 32,33.This of bonnet 29 also has " antenna " joint 34 above rear board part, is used for receiving radio frequency signals from video-game with from cable coupling, outdoor electric wire or video recorder.Receiver shown in Figure 1 does not have the common rabbit ear type of seeing or this machine antenna of other types on portable television receiver, because this class antenna bring danger can for the children that fall down on antenna when placing receiver on the floor.Some design comprises built-in aerial, and it can be used to receive when the VHF TV broadcast singal again that receives UHF broadcasting or from radio and television on the 920MHz that main frame sends." input " audio/video socket 35 and " output " audio/video plug 36 are arranged on the back of bonnet 29, be used to connect the video video cassette recorder.On the back of bonnet 29, also have " input " left side/right stereo socket 37 and " output " left side/right stereo socket 38.

Fig. 3 is the circuit schematic block diagram of the portable television receiver of children shown in Figure 1, and this receiver has the display screen that door closure is lived its chromoscope 40.In the time of on linking main power source, plug 41 offers transless LVPS 42 with traditional principal voltage with the 50/60Hz alternating current by power line 31, it carries out rectification and filtering to power line voltage, supplies with remote-control receiver circuit 43 to produce direct-current working volts.43 responses of remote-control receiver circuit are added on each circuit of television receiver to produce control signal by the modulated infrared light carrier wave of transducer 44 perception, and these will here be explained.The 50/60Hz alternating current that provides by power line 31 also is added on bipolar/double-throw on/off mains switch 45, and this switch is started by the telekinesis key on the television receiver front surface shown in Figure 1 22.Suppose that on/off mains switch 45 is in the position that it " leads to ", according to an aspect of the present invention, when and if only if left-hand door interlocking switch 48 and right door interlock switch 49 are opened greatly simultaneously, just make this 50/60Hz alternating current offer the autodegauss coil 46 and positive temperature coefficient type (posister type) thermistor 47 of series connection thereafter selectively.So, after the display screen of chromoscope 40 is outwards opened autodegauss takes place just at loud speaker 14-16 and 18-20 only.

Utilize the magnetic speaker motor that does not adopt permanent magnet in its structure, can get rid of problem the picture tube demagnetization.Utilize electromagnet can provide the loudspeaker horn coil required constant electromagnetic field, its magnetic structure is made of low remanent magnetism material, provides direct current by LVPS circuit 59 in its coil.Open up to door 13 and 17 and to allow in the door lock-switch 48 and 49 conductings just set up the stationary magnetic field afterwards.
