Abstract
The invention discloses a convenient and inexpensive teaching aid comprising a frame, a box body mounted on the frame, a controller connected with the box body, and a sound receiving module connected with the box body. The box body consists of a card slot and a control chip, which are connected. The control chip is connected with a display module and a sound amplifying module, and the display module and the sound amplifying module are disposed at one side of the box body. The controller controls on-off of the display module and the sound amplifying module. Video or pictures in a learning card can be played by the teaching aid. Moreover, the teaching aid has the function of a microphone, and teachers can explain the video or pictures through the microphone while playing the video or pictures. The teaching aid is convenient, practical, and low in cost.
Description
Technical field
The present invention relates to teaching equipment technical field, particularly a kind ofly facilitate cheap teaching tool.
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.And the classroom of general remote districts is more spacious, the classroom sound that needs to speak is very large.Therefore design a with earphone function, can play video and picture teaching tool extremely important.
Summary of the invention
The object of this invention is to provide a kind of low price, convenient and practical teaching tool.
To achieve these goals, the technical solution of employing is in the present invention:
A kind ofly facilitate cheap teaching tool, comprise frame, be installed on the casing in frame, the controller be connected with casing, the acoustic reception module be connected with casing, described casing comprises draw-in groove and is connected with control chip, and control chip is 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.
Described acoustic reception module and casing wireless connections.
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.Simultaneously by acoustic reception module and sound amplification module, with sound enlarging function, teacher can laborsaving effective explanation course, convenient and practical, improves the ability that student receives new things, and this teaching tool low price.
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; 4, acoustic reception module; 21, draw-in groove; 22, control chip; 23, display module; 24, sound amplification module.
Embodiment
Consult shown in Fig. 1-2, the invention provides and a kind ofly facilitate cheap teaching tool, comprise frame 1, be installed on the casing 2 in frame 1, and the controller 3 to be connected with casing 2, the acoustic reception module 4 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, display module 23 being set for light-emitting diode display, economize energy, sound amplification module 24 is audio amplifier.Acoustic reception module 4 and casing 2 wireless connections, acoustic reception module 4 is microphone, with switch on microphone.
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, and it is for inserting learning card, and mainly comprises the data of general study in learning card, 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; And by the data that reception acoustic reception module 4 transmits, it is play by sound amplification module 24, plays the effect of voice emplifying.
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.Acoustic reception module 4 opened, teacher can talk facing to this acoustic reception module 4, sound can be amplified broadcasting by sound amplification module 24 by the control chip in casing 2, easy to use simultaneously.
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.
