Embodiment Construction

[0020] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0021] The inventive idea of ​​the present invention is: by setting a projection unit in the projection device, the screen content of the terminal equipment such as a mobile phone is projected and enlarged, so that it is convenient for multiple people to watch the content played by the terminal equipment at the same time; For the problem of equipment playback, set the retaining device of the fixed terminal equipment as a device with a movable position and an adjustable size; considering the limited power of the terminal equipment, add a wire slot to connect the power cord to supply power to the terminal equipment.

[0022] The above-mentioned terminal device can be a mobile phone, a tablet computer, an MP4 player and other devices with self-illuminating screens; in the embodiment of the present invention, the terminal device is a m...

Abstract

The invention discloses a projection device and a method of using the same. The projection device comprises a closed housing, a lens unit disposed on the housing and a fixing device; during playing, a mobile terminal device is fixed onto the fixing device, the lens unit faces toward a screen of the terminal device and playing content on the screen of the terminal device can be projected for multiple persons to view; and meanwhile, the fixing device can also be designed as a movable and resizable base to facilitate shared playing using the projection device by a variety of different terminal devices. By use of the above technical scheme, the problem in the prior art that the screen of the terminal device is so small that the playing content on the screen is hard to shared and viewed by multiple persons for communication is solved.

Description

technical field [0001] The present invention relates to a device for projecting output, in particular to a device for enlarging and projecting content played on a screen of a terminal device and a method for using it. Background technique [0002] At present, with the popularization of terminal equipment such as mobile phones and the continuous improvement of functions, it brings great convenience to people. Various functions such as surfing the Internet, reading books, and watching movies emerge in an endless stream, giving people the enjoyment of unlimited entertainment. [0003] However, due to the small screen size of current mobile phones or other terminal devices, it is very inconvenient to share with others and to be watched by many people; although some special projectors can be connected to mobile phones for projection, they are expensive. And it can only be aimed at specific mobile phones, and still cannot realize projection playback for most terminal players. Co...
