Abstract

The present invention discloses an electrical device. The electrical device comprises: a supporting arm, a base portion connected to one end of the supporting arm, and a head portion connected to the other end of the supporting arm, wherein the head portion comprises a projector which is fixed to the head portion by a projector bracket and is at least used for carrying out projection on a first region of a placed plane of the base portion, and a roller which is connected with the projector and is used to adjust an image projected by the projector; and a first portion of the roller is exposed on a first outer surface of a housing of the head portion. By applying the technical scheme of the present invention, at least the problem of inconvenience for adjusting the projector in the prior art can be solved, and the usage experience of a user is promoted.

Description

technical field [0001] The present invention relates to the field of terminal equipment, in particular to an electronic equipment. Background technique [0002] With the development of electronic technology, the application range of projectors is becoming wider and wider, and it has been widely used in fields such as homes, offices, schools, and entertainment venues. [0003] At present, there are many ways to install the projector, such as desktop placement, hoisting, bracket placement and so on. However, in some cases, such as a projector mounted under a ceiling, it is not easy to adjust it when it is installed at a higher position, for example, it is inconvenient to adjust a projector installed on the ceiling of a classroom. Contents of the invention [0004] In view of this, the present invention expects to provide an electronic device, which can at least solve the problem of inconvenient adjustment of the projector in the prior art, and improve user experience.
