The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features. The description is not to be considered as limiting the scope of the embodiments described herein.
The term “comprising” means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in a so-described combination, group, series, and the like.
FIG. 1 illustrates a projection device 100 includes a shell 20 and a fixing module 80. The shell 20 includes a top shell 22, a bottom shell 24 and a sidewall 26 fixed between the top shell 22 and the bottom shell 24. The fixing module 80 is fixed to the bottom shell 24.
FIGS. 3 and 4 illustrate the projection device 100 further includes a projection module 30, a motherboard 40, an image capturing module 50, a loudspeaker 60 and a power module 70. The projection module 30, the motherboard 40, the image capturing module 50, the loudspeaker 60 and the power module 70 are fixed in the shell 20. The power module 70 electrically connects to and provides power to the projection module 30, the motherboard 40, the image capturing module 50 and the loudspeaker 60.
The projection module 30 connects to the motherboard 40. The motherboard 40 transmits image data of a project to the projection module 30. FIG. 2 illustrates the projection module 30 includes a projection lens 32. The projection module 30 receives the image data and projects the images to a projection medium through the projection lens 32. Thus, an user can play the project on the projection medium. The image capturing module 50 captures playing images on the projection medium and transmits the playing images to the motherboard 40. The motherboard 40 determines the next image according to the playing image and transmits the next image to the projection module 30. The projection module 30 projects the next image to the projection medium. Thus, the user can continuously view the project.
The loudspeaker 60 connects to the motherboard 40. The motherboard 40 further transmits video data corresponding to the image data to the loudspeaker 60. The loudspeaker 60 outputs sound consistently with the video data.
The top shell 22 and the bottom shell 24 are parallel to each other. FIG. 4 illustrates the top shell 22 defines an opening 28 for projecting the image out to the projection medium. In the embodiment, the projection module 30 is fixed between and parallel to the top shell 22 and the bottom shell 24. FIG. 2 illustrates that a reflector 25 is obliquely extended from an edge of the opening 28 toward the bottom shell 24. The reflector 25 faces the projection lens 32. The projection lens 32 projects the image to the reflector 25. Then, the reflector 25 reflects the image to the projection medium. In another embodiment, the projection module 30 is perpendicularly fixed between the top shell 22 and the bottom shell 24. The projection lens 32 is opposite to the opening 28. The projection lens 32 projects the image to the projection medium
FIG. 3 illustrates that the top shell 22 further defines a first through hole 21 and a number of second through holes 23. The image capturing module 50 includes a camera lens 52. The camera lens 52 is opposite to the first through hole 21. The loudspeaker 60 is opposite to the second through hole 23. The sound output by the loudspeaker 60 is transmitted out of the shell 20 through the second through hole 23.
The embodiments shown and described above are only examples. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the details, including in matters of shape, size, and arrangement of the parts within the principles of the present disclosure, up to and including the full extent established by the broad general meaning of the terms used in the claims.
