1. Field of the Invention
The present invention relates to a remote controller, especially to a remote controller with main body built in with USB connection port electrically connected to a receiver.
2. Description of Prior Art
The consumer electronic product and electronic storage media have rapid progress recently as the advance of electronic technology and prevailing of computer system. More particularly, people gradually use notebook computer and projector for presentation and lecture. The presentation material of notebook computer is projected to screen or whiteboard by the projector for view by the audience.
When the presentation is to be changed to next or previous page, the lecturer generally needs to approach the computer and press page-up or page-down key. The frequent key pressing operation on the computer will interrupt the presentation.
Therefore, a remote controller is developed to control the page switching for computer. The remote controller includes a receiver therein, and a USB connector arranged at front face thereof and pluggable to a USB port of a notebook computer. When a speaker wants to control the screen content, he can operate the remote controller to send a control signal. In this way, the page of presentation can be changed or cursor can be moved. However, the prior art receiver can only perform signal transmission/reception function and no further function is available. It is desirable to provide a function integration of remote controller and flash memory/thumb drive.
The present invention is intended to integrate playback function of digital audio data to a remote controller.
Accordingly, the present invention provides a multi-function remote controller, the remote controller includes:
The features of the invention believed to be novel are set forth with particularity in the appended claims. The invention itself however may be best understood by reference to the following detailed description of the invention, which describes certain exemplary embodiments of the invention, taken in conjunction with the accompanying drawings in which:
The main body 1 includes an accommodation space 11 and the accommodation space 11 includes a first chamber 12 and a second chamber 13. The first chamber 12 is used to place battery 3 for supplying working power. A USB connection port 14 is placed in the second chamber 13. The USB connection port 14 is electrically connected to a control circuit (not shown) in the main body 1. A cover plate 15 is arranged atop the accommodation space 11.
The receiver 2 includes a USB connector 21 at front face thereof The USB connector 21 is electrically connected to a signal-receiving circuit (not shown) therein and the USB connection port 14. A memory is provided for the receiver circuit for digital storage such as digital audio file.
Moreover, when the receiver 2 is not operated at signal reception mode, the receiver 2 can download digital audio file from the host computer 4. The digital audio file is stored in the memory in the receiver 2 through the USB connection port 41 and the USB connector 21.
Although the present invention has been described with reference to the preferred embodiment thereof, it will be understood that the invention is not limited to the details thereof. Various substitutions and modifications have suggested in the foregoing description, and other will occur to those of ordinary skill in the art. Therefore, all such substitutions and modifications are intended to be embraced within the scope of the invention as defined in the appended claims.
