Embodiment
The preferred embodiment of a kind of projection screen of the present invention and optical projection system now is described in conjunction with the accompanying drawings.
With reference to figure 1-3, described projection screen comprises curtain 1, spool 2, motor 3, housing 4, erecting frame 5, sound equipment 6, controller 90 in the present embodiment.Described spool 2 links to each other with curtain 1, and this spool 2 is used for launching or drawing in described curtain 1.The motor shaft of described motor 3 links to each other with spool 2, and this motor 3 is used to drive this spool 2 and rotates expansion or the gathering that realizes described curtain 1.
Form an accepting groove 41 on the described housing 4, the below of this accepting groove 41 has opening 411 for curtain 1 free folding and unfolding.Described motor 3 is fixedly installed in the accepting groove 41 of housing 4.Described erecting frame 5 is arranged at the rear side of housing 4, and this erecting frame 5 is used for hanging on the wall whole projection screen or other article.Described sound equipment 6 is installed on described housing 4 front sides, and this sound equipment 6 comprises left sound equipment 61, middle sound equipment 62, the right sound equipment 63 that is arranged in order on housing 4.Described sound equipment 6 is a kind of 5.1 sound channel surround sound sound equipments.Be coated with sound equipment cover 64 on the described sound equipment 6, it is circular-arc and be fixedly installed in the outside surface of described housing 4 that this sound equipment cover 64 is bar shaped.This sound equipment cover 64 protects sound equipment 6 effectively, prevents that foreign matter such as dust from falling into sound equipment 6 and damaging sound equipments 6 and influence acoustics.
The controller 90 that is used to control described motor 3 also is installed on the housing 4 of described projection screen 60.For more easy to use, this projection screen also comprises a telepilot 100, and described controller 90 is provided with wireless signal receiver 91.This telepilot 100 can be infrared remote controller, and wireless signal receiver 91 is corresponding can be the probe of band infrared inductor.
When telepilot 100 sent starting-up signal, the wireless signal receiver 91 of controller 90 was carried control signal to motor 3 after receiving starting-up signal, opens sound equipment 6 simultaneously.Like this, motor-driven spool 2 rotates, and curtain 1 slowly launches downwards from accepting groove 41 lower opening 411.When this projection screen can projection, can come to sound from three zones, left, center, right of projection screen by left sound equipment 61, middle sound equipment 62, right sound equipment 63, so left sound equipment 61, middle sound equipment 62, right sound equipment 63 can imitate the object that shows in the projection screen three sound that send in the zone from left, center, right respectively.For example, in projection screen, show three people, these three people are presented at three zones, left, center, right in the projection screen respectively, people's word for the zone, left, center, right is play by left sound equipment 61, middle sound equipment 62, right sound equipment 63 respectively, like this, make picture and sound cooperate more true to naturely.When needs draw described curtain 1 in, motor-driven spool 2 backward rotation, curtain 1 upwards slowly draws in from the opening part of housing 4 belows.
Therefore the projection screen of present embodiment not only can synchronous playing sound in the Display projector picture, has the function that can play shadow, sound, picture simultaneously, and can play sound according to the picture subregion.
With reference to figure 4-5, described optical projection system comprises projection screen 60 in the present embodiment, projector 70, video/audio signal generator 80.Described projector 70 is used for being converted to image projection in described projection screen 60 with receiving vision signal.This projection screen 60 is the projection screen in the foregoing description.With reference to figure 1-3, this projection screen comprises curtain 1, spool 2, motor 3, housing 4, erecting frame 5, sound equipment 6, controller 90, telepilot 100 simultaneously, and this sound equipment 6 comprises left sound equipment 61, middle sound equipment 62, the right sound equipment 63 that is arranged in order on housing 4.Because the foregoing description is described in detail this projection screen 60, just no longer its structure has been given unnecessary details one by one here.In order to make sound equipment reach better effect, this optical projection system also is provided with mega bass and rings 61 below projection screen 60, and projector 70 is provided with the surround sound 71 of one.
Described controller 90 rings 61 with mega bass respectively, surround sound 71, projector 70, and the motor 3 in video/audio signal generator 80 and the projection screen 60 links to each other with sound equipment 6.Described video/audio signal generator 80 rings 61 and surround sound 71 with projector 70, sound equipment 6, mega bass respectively again.This video/audio signal generator 80 is used for sound signal is sent to sound equipment and vision signal is sent to projector 70.
Described controller 90 can be a top box of digital machine, and this wireless signal receiver 91 is used to receive the control signal that telepilot 100 sends.Described telepilot 100 can be an infrared remote controller, and respective wireless signal receiver 91 can be an infrared signal receiver.
When telepilot 100 when controller 90 sends starting-up signal, the motor 3 in the controller 90 control projection screens 60 launches curtains 1, opens projector 70 simultaneously, video/audio signal generator 80, sound equipment 6, mega bass ring 61 and surround sound 71.With telepilot 100 remote controllers 90 time, projector 70 can be to the picture at projection screen 60 projections control interface, and the operator can operate according to the demonstration at control interface.When the picture of display control interface on the curtain 1, video/audio signal generator 80 is in the stand-by operation state.When needs are play what program of what file, the operator utilizes telepilot 100 to select according to the control interface that shows and straighforward operation controller 90 is finished.
When playing, described video/audio signal generator 80 sends to projector 70 with the video data of want projection, and this projector 70 is converted to image projection to described projection screen 6 with video data.Simultaneously video/audio signal generator 80 sends to sound equipment 6, mega bass respectively with sound signal and rings 61 and surround sound 71, and the image synchronization by these stereo sets and projection plays sound.
When telepilot 100 when controller 90 sends off signal, controller 90 sends instruction automatically with projector 70, video/audio signal generator 80, sound equipment 6, mega bass ring 61 and surround sound 71 close, also control motor 3 simultaneously and draw curtains 1 in.Native system need not to go one by one to turn off or open each parts in the system, and is simple to operation, quick and directly perceived.Wherein video/audio signal generator 80 can be video-audio program playback equipments such as computer, DVD player and digital video machine.
Certainly, described spool also can not need motor to drive, and can directly be hubbed in the accepting groove of housing, for the curtain rolling on it.
Above disclosed only is preferred embodiment of the present invention, can not limit the present invention's interest field certainly with this, and therefore the equivalent variations of being done according to the present patent application claim still belongs to the scope that the present invention is contained.
