Abstract
The utility model discloses a multimedia controller based on the bluetooth wireless communication technology, which comprises a main controller, a keyboard input module, a laser emission module, a bluetooth LED indicating lamp, a bluetooth transmit-receive module and a bluetooth USB adapter. The main controller acquires a button signal and then data are sent to the bluetooth USB adapter connected with a computer via the bluetooth transmit-receive module. The received data are decoded by the computer and the corresponding operation is sent to a windows system so as to realize the page-turning operation on PPT files of the computer. Meanwhile, the operations such as pausing, playing, full-screening, scaling, speeding up, volume controlling of storm video files and single clicking on a left key or a right key can also be realized. By utilizing the multimedia controller, the operations of controlling a computer and a multimedia projector and turning the pages of PPT files are operated in a wireless remote control manner. The multimedia controller is suitable for the multimedia demonstration in places such as classrooms, lecture halls and the like. By utilizing the multimedia controller, a teacher or a speaker does not need to stay beside a computer any more and can freely move about in a classroom or a lecture hall. Therefore, the teacher or the speaker can better interact and communicate with the audience, so that the teaching and lecture effect is improved.
