Description
Technical field the utility model belongs to the multimedia teaching technical field, relates to a kind of suspension type multimedia teaching apparatus.
The background technology prior art multimedia education system generally be with desktop computer (or laptop computer), projector, central controller, material object display platform, wireless microphone, power amplifier, audio amplifier, screen and various wire rod, integrated being installed in the place to operate schools realized multimedia teaching.But existing multimedia education system exists equipment cost than higher, complex structure and the lower deficiency of integrated level, and the installation site of each appliance arrangement relatively disperses, and general system is installed on the several different positions, causes the inconvenience in the practical operation.
The summary of the invention the purpose of this utility model is to solve the technical matters that there is practical operation inconvenience in prior art, a kind of suspension type multimedia teaching apparatus is provided, be equipped with the computer main control system within it, can constitute multimedia education system as long as connect projector and audio amplifier, last class hour of teacher is as long as with behind the USB flash disk insertion computer main control system that carries, can directly move the teaching courseware that carries.
For achieving the above object, the utility model suspension type multimedia teaching apparatus, it comprises casing, casing is provided with hanging nose, be provided with power amplification unit and the wireless speech receiving element and the action button that are connected with power amplification unit in the casing, casing is provided with audio input interface unit and the horn interface that is connected with power amplification unit; Its main points are also to be provided with the computer main control system in the described casing, and casing is provided with USB interface and the RJ45 interface that is connected with the computer main control system, and the computer main control system is connected with power amplification unit; Be provided with the central controller that is connected with the computer main control system in the described casing, casing is provided with projector's interface, material object display platform interface, electronic whiteboard interface, screen interface that is connected with central controller and the operational module that carries out wire communication with the computer main control system.
Described operational module is the action button of carrying out wire communication with the computer main control system.
The utility model is gathered the computer main control system in the existing voice public address system, serving as a teacher needs to adopt various files to be equipped with when giving lessons, only need displacement disc is plugged into USB interface, re-using action button selects file, the computer main control system just can read corresponding file and play, and carry out audio frequency by power amplification unit and amplify, by central controller the VGA signal is amplified the output projection, greatly improved convenience; And compact conformation, install easily, easy to use.
Appended drawings is the utility model circuit structure principle schematic.
Among the figure: 1, casing 2, audio input interface unit 3, hanging nose 4, wireless speech receiving element 5, power amplification unit 6,7, horn interface 8, central controller 9, projector's interface 10, material object display platform interface 11, electronic whiteboard interface 12, screen interface 13, action button 14, action button 15, computer main control system 16, RJ45 interface 17, USB interface
Embodiment is with reference to accompanying drawing, it comprises casing 1 the utility model, casing 1 is provided with hanging nose 3, be provided with power amplification unit 5 and wireless speech receiving element 4 that is connected with power amplification unit 5 and action button 14 in the casing 1, casing 1 is provided with audio input interface unit 2 and the horn interface 6,7 that is connected with power amplification unit 5; Also be provided with computer main control system 15 in the casing 1, casing 1 is provided with usb 17 and the RJ45 interface 16 that is connected with computer main control system 15, and computer main control system 15 is connected with power amplification unit 5; Be provided with the central controller 8 that is connected with computer main control system 15 in the casing 1, casing 1 is provided with projector's interface 9, material object display platform interface 10, electronic whiteboard interface 11, screen interface 12 that is connected with central controller 8 and the action button 13 of carrying out wire communication with computer main control system 15; Action button 13,14 is arranged on the casing 1; Central controller 8 may command projectors and the automatic open and close machine of computer are controlled the automatic ascending, descending of screen simultaneously.
After the start that plugs in, the first initialization of computer main control system 15 meetings of the present utility model shows main interface then in screen, just can select required file operate by action button 14 and 13.The teacher need adopt various files to be equipped with when giving lessons, only need displacement disc is plugged into USB interface, re-using action button selects file, computer main control system 15 just can read corresponding file and play, the VGA signal is read by the input terminal of computer main control system 15 or external material object display platform interface 10, and exports central controller 8 to, by action button 13 controls, realize that selecting computer still is that material object display platform VGA signal outputs to projector, is projected in the screen by projector again.
Export loudspeaker to and project in the screen and can amplify by the utility model such as the voice signal of wireless microphone output, from the signal of computer (comprise the file signal of computer main control system self storage and from the signal of USB interface and RJ45 interface), material object display platform, electronic whiteboard etc.
