Description
Technical field
The utility model relates to a kind of multimedia education system, is specifically related to a kind of portable multimedia tutoring system.
Background technology
Along with the development of computer technology, multimedia technology is ripe gradually, and multi-media classroom or meeting room are come into multiple fields such as teaching, training unit and company gradually.Various kinds of schools and R&D institution, all building multi-media classroom or the multi-functional report Room, and traditional construction scheme is to be equipped with computing machine, multimedia projector, electronic giant-screen, DVD and stereo set etc., reaches the synchronous teaching efficiency of sound, image and word.In multi-media classroom, be generally furnished with computer and projector, in the process of speech or explanation, speaker often needs the content of explanation operate and point out, and carries out speech sound eeplaining by microphone simultaneously.There is the weak point of following several respects in traditional Mobile Teaching system: (1) product composition is more, has comprised multiple Voice & Video device, and various types of electronic equipments are comparatively various, and it is more difficult to manage; (2) operating process is loaded down with trivial details, separate device switching manipulation, complex redundancy; (3) install, arrange comparatively trouble, multiple different electron device is connected, frequency modulation etc. are processed very loaded down with trivial details.
Summary of the invention
The technical matters that the utility model solves has been to provide a kind of portable multimedia tutoring system, traditional optical projection system and other control system are simplified with integrated, thereby dwindle the apparent size of whole multimedia system, used like this, operate, carried and installed all convenient.
The technical solution of the utility model is: a kind of portable multimedia tutoring system, it is characterized in that mainly by left substrate, right substrate, bearing pin, notebook computer, handwriting pad, projector support bar, supporting substrate, micro projector and projection screen form, described left substrate and a side of right substrate are respectively equipped with connecting hole, and by the bearing pin that matches with connecting hole by hinged to left substrate and right substrate, position at left substrate and four angles of right B.B.P is respectively equipped with sucker, on described left substrate, be placed with notebook computer, on right substrate, be fixed with respectively handwriting pad and projector support bar, this projector support bar is made up of the telescopic vertical rod of three joints, and the top at projector support bar is provided with supporting substrate, on described supporting substrate, be fixed with micro projector by trip bolt, described projection screen is arranged at a side relative with micro projector camera lens.
One side of notebook computer described in the utility model is respectively equipped with USB interface and signal wire hole, one side of described micro projector is respectively equipped with signal wire hole and power lead hole, wherein the signal wire hole of notebook computer and the signal wire hole of micro projector are connected by signal wire, and the power lead hole of the USB interface of notebook computer and micro projector is by power lead and power connection.
The portable multimedia tutoring system that the utility model provides is compared with traditional Mobile Teaching system, by adopting modern integrated equipment, as micro projector, notebook computer and handwriting pad etc., traditional optical projection system and other control system are simplified with integrated, this utility model is without special Electronic platform, liquid crystal display and sound-box device etc., thereby dwindle the apparent size of whole system, used like this, operate, carried and installed all more simple and convenient.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Drawing explanation: 1, left substrate, 2, right substrate, 3, bearing pin, 4, connecting hole, 5, sucker, 6, notebook computer, 7, handwriting pad, 8, projector support bar, 9, supporting substrate, 10, trip bolt, 11, micro projector, 12, projection screen, 13, USB interface, 14, signal wire hole, 15, power lead hole.
Embodiment
Describe by reference to the accompanying drawings embodiment in detail.A kind of portable multimedia tutoring system, mainly by left substrate 1, right substrate 2, bearing pin 3, notebook computer 6, handwriting pad 7, projector support bar 8, supporting substrate 9, micro projector 11 and projection screen 12 form, described left substrate 1 and a side of right substrate 2 are respectively equipped with connecting hole 4, and by the bearing pin 3 that matches with connecting hole 4 by hinged with right substrate 2 left substrate 1, be respectively equipped with sucker 5 in left substrate 1 and the position at right substrate 2 four angles, bottom, on described left substrate 1, be placed with notebook computer 6, on right substrate 2, be fixed with respectively handwriting pad 7 and projector support bar 8, this projector support bar 8 is made up of the telescopic vertical rod of three joints, and be provided with supporting substrate 9 on the top of projector support bar 8, on described supporting substrate 9, be fixed with micro projector 11 by trip bolt 10, described projection screen 12 is arranged at a side relative with micro projector 11 camera lenses.
One side of notebook computer 6 described in the utility model is respectively equipped with usb 13 and signal wire hole 14, one side of described micro projector 11 is respectively equipped with signal wire hole 14 and power lead hole 15, wherein the signal wire hole 14 of notebook computer 6 and the signal wire hole 14 of micro projector 11 are connected by signal wire, and the usb 13 of notebook computer 6 and the power lead hole 15 of micro projector 11 are by power lead and power connection.
Principle of work of the present utility model is: first open left substrate and right substrate, lie in a horizontal plane on desk, then difference placing laptop and handwriting pad on left substrate and right substrate, now sucker adsorbs on the table under the effect of gravity, projector support bar is installed on the correspondence position of right substrate, then in the supporting substrate of projector support bar, place micro projector, and screw the fixing micro projector of trip bolt, then power lead hole and USB interface are connected and power connection by a power lead, again notebook computer signal wire hole is connected by signal wire with micro projector signal wire hole, projection screen is hung on to the position relative with micro projector camera lens, the height of adjusting projector support bar makes micro projector relative with projection screen, then open notebook computer and micro projector, this multimedia education system can enter duty.
