Detailed Description
The present invention will be described in further detail with reference to examples, but the embodiments of the present invention are not limited thereto.
Example 1:
referring to fig. 1, fig. 2 and fig. 3, a suspendable laser television comprises a flexible screen 1 and a laser television projection device 2, which are placed near a wall 3, wherein the flexible screen 1 comprises a flexible screen 11 and a magnetic suspension device 12 connected with the flexible screen 11; the laser television projection device 2 comprises a laser projection generation module 21 and a storage module 22 for storing the flexible screen 1, wherein the laser projection generation module 21 and the magnetic suspension device 12 generate magnetic fields with the same magnetism for driving the flexible screen 1 to suspend when being electrified.
When the flexible screen device is used for laser projection, the flexible screen 1 capable of being curled supplies electricity to the flexible screen 11 and the magnetic suspension device 12, the flexible screen 1 capable of being curled controls the tension of a conductive material in the flexible screen 11 through current so that the flexible screen 11 can be unfolded, meanwhile, the magnetic suspension device 12 and the laser projection generation module 21 generate a magnetic field with the same magnetism, the magnetic suspension device 12 is made to suspend, and therefore the flexible screen 1 capable of being curled is driven to suspend.
When the flexible screen is used, the flexible screen 1 can be curled to control the current of the flexible screen 11 and the magnetic suspension device 12 to be weakened to power-off, in the process, the flexible screen 11 is curled, and the magnetic suspension device 12 drives the flexible screen 11 to descend to the storage module 22.

A gravity center sensor and a displacement sensor are arranged in the rotor. A conductive ball is arranged in the rotor, and the ball is divided into an upper partition, a lower partition, a left partition and a right partition, so that the current can be controlled in the partitions.

If a leftward shift of the flexible screen is detected by the sensor, the controller increases the current to the right segment of the sphere until the flexible screen remains balanced. If a rightward shift of the flexible screen is detected by the sensor, the opposite is true. If a forward deflection of the flexible screen is detected by the sensor, the controller increases the current to the sub-sphere segment until the flexible screen remains vertically up and down. If a rearward deflection of the flexible screen is detected by the sensor, the reverse is true. Therefore, the controller identifies the floating position of the flexible screen 11 and whether the screen is tilted according to the detection signals of the center sensor and the displacement sensor, and controls the center of gravity and the balance of the whole flexible screen 1 by controlling the current of the first wire coil of the rotor, for example, when the current of the first coil is within a preset value a or a preset range, the balance of the flexible screen 11 can be maintained, but when the current is greater than the preset value a or the preset range, the flexible screen 11 will tilt forward; when the current is less than the preset value a or the preset range. Therefore, when the flexible screen 11 is tilted forward, the current can be controlled to decrease; conversely, the control current increases. The controller adjusts the balance according to the degree of positional deviation of the displacement sensor.
The rotor detects whether the screen surface of the flexible screen 1 which can be curled is vertical or horizontal through the gravity sensor and the displacement sensor. The controller controls the center of gravity shift of the rotor and the position of the rollable flexible screen 1 according to the detected result so as to achieve the vertical screen surface and the horizontal screen surface.
