Abstract

The invention discloses a user interface of a multimedia device, which comprises a projection frame. A projection cavity is provided in the projection frame, and the left and right sides of the projection cavity are respectively connected with a lifting cavity. The left and right sides of the side walls are respectively rotated with upper and lower symmetrical upper and lower shafts, and the outer circular surfaces of all the upper and lower shafts are fixed with upper and lower pulleys, and upper and lower belts are wound between the upper and lower pulleys. The left and right sides of the lifting cavity on the left and right sides are respectively rotated and provided with vertically symmetrical lower lifting shafts. The present invention can accurately determine the position of the projection device by manually adjusting the position of the projection positioning point according to the needs of the general device user for the projection screen. The position and size of the projected screen, and the up and down movement of the positioning point and the synchronization of left and right movement ensure the symmetry of the screen and avoid skewed images. In addition, the movement of the positioning point can also be controlled by remote control, which is convenient and practical.

Description

technical field [0001] The present invention relates to the technical field of multimedia equipment, in particular to a multimedia equipment user interface. Background technique [0002] A projector, also known as a projector, is a device that can project images or videos onto a screen. During the use of the projector, it is often necessary to adjust the position and size of the projection screen. The adjustment function often cannot be quickly and effectively adjusted to the projection screen that meets the user's requirements, because the adjustment of the screen and the position judgment of the real object cannot be quickly and one-to-one correspondence, which makes the adjustment difficult. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multimedia device user interface, which solves the problem of difficulty in adjusting the size and position of the screen of the projection device. [0004] The present in...
