Abstract

The invention belongs to the technical field of electronic products, and especially relates to a multifunctional projection device. The device comprises a projection light machine and a housing. An outer side wall of the housing is provided with a loudspeaker which is rotatingly connected with the outer side wall of the housing and electrically connected with the projection light machine. The interior of a cavity formed by the enclosing of the housing is provided with a transmission shaft which is fixedly connected with the loudspeaker and the projection light machine. An adjustment device which is used for adjusting a projection angle is disposed between the transmission shaft and the housing. A side wall, opposite to a lens of the projection light machine, of the housing is provided with a window, and the window is provided with a detachable projection screen. When the device is in use, an image can be projected on the projection screen, and also the projection screen can be opened to enable the image to be projected on a wall, thereby solving a problem that the number of projection mode is very small. The device can provide different projection modes according to the different needs of a user. In use, the loudspeaker can be rotated to drive the projection light machine fixedly connected with the transmission shaft to rotate, thereby achieving the purpose of adjusting the projection angle.

Description

Technical field [0001] The invention belongs to the technical field of electronic products, and in particular relates to a multifunctional projection device. Background technique [0002] With the advancement of society and the development of technology, more and more parent-child smart toys have entered people’s daily lives. Smart toys are equipped with projection devices. Parents can use remote Internet technology to remotely control, play and project videos. On the wall, the projection device of the existing parent-child smart toy is fixed inside the toy without a corresponding position adjustment mechanism. The position of the projection area can only be adjusted by moving the entire product during projection, and the single projection mode cannot meet the demand. Summary of the invention [0003] The technical problem to be solved by the embodiments of the present invention is to provide a multifunctional projection device, which aims to solve the problem of a single projecti...
