Abstract
The invention discloses a low-cost teaching aid tool which comprises a rack, a box mounted on the rack as well as a controller connected with the box, wherein the box comprises a card slot and a control chip which are connected, the control chip is connected with a display module and a voice amplification module respectively, the display module and the voice amplification module are located on one side of the box respectively, and the controller controls opening and closing of the display module and the voice amplification module. A teaching card is inserted into the card slot of the teaching aid tool, the controller controls the display module to perform display and controls the voice amplification module to play voice, accordingly, a teacher can explain the course to students in a form of graphs and voice, the new thing reception capability of the students is improved, and the teaching tool is cheap.
Description
Technical field
The present invention relates to teaching equipment technical field, particularly a kind of teaching tool of low cost.
Background technology
In school instruction process, especially in mathematical education, for making student better understand, teacher often needs to coordinate various on-the-spot demonstration while explanation, plays some videos or picture.Current great majority adopt multimedia education system, but this system price is expensive, in some, the primary school in western or remote mountain area, middle school owing to being subject to fund restriction, can not effectively be promoted.
Summary of the invention
The object of this invention is to provide a kind of low price, teaching tool that practicality is high.
To achieve these goals, the technical solution of employing is in the present invention:
A kind of teaching tool of low cost, comprise frame, be installed on the casing in frame, and the controller to be connected with casing, described casing comprises draw-in groove and is connected with control chip, control core to be connected with display module and sound amplification module respectively, and described display module, sound amplification module lay respectively at the side of casing, described controller controls the open and close of display module and sound amplification module.
Preferably, described controller is connected with casing is wired or wireless.
Preferably, described display module is liquid crystal display or light-emitting diode display.
The present invention has following beneficial effect: by being positioned in classroom by this teaching tool, and teaching card is inserted in draw-in groove, and then shown by controller control display module, control sound amplification module to play sound, teacher can be made like this to give student explain course with excellent pictures and texts, improve the ability that student receives new things, and educational aid has low price, the feature that practicality is high.
Accompanying drawing explanation
Fig. 1 is the one-piece construction figure of teaching tool of the present invention;
Fig. 2 is the module map of box house of the present invention.
Description of reference numerals: 1, frame; 2, casing; 3, controller; 21, draw-in groove; 22, control chip; 23, display module; 24, sound amplification module.
Embodiment
Consult shown in Fig. 1-2, the invention provides a kind of teaching tool of low cost, comprise frame 1, be installed on the casing 2 in frame 1, and the controller 3 to be connected with casing 2, wherein: casing 2 comprises draw-in groove 21 and is connected with control chip 22, control chip 22 is connected with display module 23 and sound amplification module 24 respectively, and described display module 23, sound amplification module 24 lay respectively at the side of casing 2, described controller 3 controls the open and close of display module 23 and sound amplification module 24.And as required, controller 3 can be set and be connected with casing 2 is wired or wireless.And display module 23 is set for liquid crystal display or light-emitting diode display.Sound amplification module 24 is audio amplifier.
General, in order to better realize the carrying of mathematical education aid of the present invention and installation etc., what to arrange frame 1 be Liftable type, and in the lower end of frame 1, scroll wheel is installed.Wherein, draw-in groove 21 is general draw-in groove, it is for inserting learning card, and in learning card, mainly comprise the data of general study, as various mathematical model, mathematical formulae, theory etc., arrange control chip 22 is general dsp chip simultaneously, is mainly used in the data of the learning card being arranged in draw-in groove 21 to be converted to the data that the displayable data of display module 23 and sound amplification module 24 can be play.
Composition graphs 1 and the course of work of Fig. 2 to mathematical education aid of the present invention are explained as follows again below: teacher in use, teaching card can be inserted in the draw-in groove 21 of casing 2, then control controller 3 and open display module 23, now the data that the data of the teaching card in draw-in groove 21 are separately converted in display module 23 show by control chip 22, and the data be converted in sound amplification module 24 play sound.
Above-described embodiment is the present invention's preferably embodiment; but embodiments of the present invention are not restricted to the described embodiments; and other any do under not deviating from Spirit Essence of the present invention and principle change, modification, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection scope of the present invention.
