Specific embodiment
As shown in Figures 1 and 5, multimedia equipment 100 includes bracket 10, movable plate, display device 30 and multiple mutual inductance lists
Member.
The movable plate is installed on the bracket 10.The display device 30 is installed on the bracket 10.The shifting
Movable plate can move on the bracket 10.For example, the movable plate is slidably mounted on the bracket 10 and is located at the display
30 front of device.
In specific implementation, the movable plate can be blackboard or electronic whiteboard.It can by the blackboard or electronic whiteboard
Writing displaying is carried out, easily convenient for interaction.Display device 30 then can be used for playing multimedia file, with the blackboard or electronics
Blank is used cooperatively.
The multiple mutual inductance unit is respectively arranged in the movable plate and the display device 30.The movable plate is opposite
When the display device 30 is mobile, movable plate described in the mutual inductance unit senses is believed relative to the position of the display device 30
Breath, the display device 30 is according to the positional information and pre-defined rule switch operating state.
In specific implementation, the multimedia equipment 100 may include one or more movable plates.Below with the multimedia
For equipment 100 including being illustrated for two movable plates, i.e., the described multimedia equipment 100 includes that first movement plate 20 and second move
Movable plate 40.It is understood that in other embodiments, the multimedia equipment 100 may include one or more movable plates
The case where can refer to following implementation realization.
The movable plate includes first movement plate 20 and the second movable plate 40.The first movement plate 20 and the second movable plate
40 are slidably mounted on the bracket 10.The first movement plate 20 and the second movable plate 40 are symmetrically disposed on the display device
30 front.The first movement plate 20 and the second movable plate 40 are moved, then the first movement plate 20 and the second movable plate 40
It is movable to the position (as shown in any figure of the Fig. 2 into Fig. 4) for blocking the display device 30, or reverse movement is to described aobvious
The two sides (as shown in Figure 1) of showing device 30.
The first movement plate 20 is equipped with the first mutual inductance unit 210, and second movable plate 40 is equipped with the second mutual inductance
Unit 410.The display device 30 be equipped with the matched third mutual inductance unit 310 of the first mutual inductance unit 210 and with institute
State the matched 4th mutual inductance unit 340 of the second mutual inductance unit 410.
The third mutual inductance unit 310 is matched with the first mutual inductance unit 210 to sense 20 phase of first movement plate
For the first location information of the display device 30.The 4th mutual inductance unit 340 is matched with the second mutual inductance unit 410
To sense second location information of second movable plate 40 relative to the display device 30.
In a preferred embodiment, the display device 30 can also include display unit 320 and control unit 330.
Described control unit 330 and the display unit 320, the second mutual inductance unit 410 and the 4th mutual inductance list
Member 340 communicates to connect.
Described control unit 330 is cut according to the first location information and the second location information and pre-defined rule control
Change the working condition of the display unit 320.
For example, the first mutual inductance unit 210, the second mutual inductance unit 410, third mutual inductance unit 310, the 4th mutual inductance unit
340 can be range sensor.First location information is first distance of the first movement plate 20 relative to the display device 30, right
It answers, second location information is second distance of second movable plate 40 relative to the display device 30.
In specific implementation, control unit 330 can be less than predetermined value time control in the first distance or the second distance
The display unit 320 is made to close.
As shown in fig.2, the first distance becomes when the first movement plate 20 mobile to the display device 30
It is small.When the first distance is less than a scheduled critical value, the first movement plate 20 is blocked before the display device 30
Portion formed the first blocked area 350 area it is excessive, cause display device 30 can not normal use, can conclude that display device at this time
30 display unit 320 can close.Therefore, control unit 330 controls the closing of display unit 320 at this time.
Similarly, as shown in fig.3, when second movable plate 40 mobile to the display device 30, described second away from
From becoming smaller.When the second distance is less than a scheduled critical value, second movable plate 40 is blocked in the display device
30 fronts formed the second blocked area 360 area it is excessive, cause display device 30 can not normal use, can conclude that display at this time
The display unit 320 of device 30 can close.Therefore, control unit 330 controls the closing of display unit 320 at this time.
It is similar, as shown in figure 4, control unit 330 can be both less than predetermined in the first distance and the second distance
The display unit 320 is controlled when value to close.
In another preferred embodiment, the multimedia equipment 100 can also include a clock unit 50, the clock
Unit 50 and described control unit 330 communicate to connect, and clock unit 50 is used for timing.
After described control unit 330, which controls the display unit 320, closes and be spaced a first time, the control is single
Further control 30 suspend mode of display device of member 330.
Further, after described control unit 330, which controls the display unit 320, closes and be spaced for the second time, institute
Stating control unit 330, further control display device 30 is shut down.
