Abstract
The utility model discloses a teaching aid, which comprises an electronic pointer circuit integrated board, a microphone circuit integrated board, an electronic pointer laser head and a microphone, wherein the top part of a seal plate is provided with the electronic pointer laser head and a microphone receiver, grooves of the microphone circuit integrated board and the microphone circuit integrated board are arranged in the seal plate, the lower part of the seal plate is provided with a cell, a microphone cord is led out from the right lower corner of the seal plate, the side surface of the seal plate is provided with a power switch, and the back surface of the seal plate is provided with a cell cover for sealing the cell and a clip. The utility model has the advantages that the electronic pointer and a collar clip type radio microphone are combined as one via the seal plate and share the cell, so the energy is saved and the cost is reduced.
Description
Technical field:
The utility model is a kind of a kind of teaching aid that tie clip formula wireless microphone and electronic teacher pointer are united two into one.
Background technology:
At present, multimedia teacher generally usefulness all be tie clip formula wireless microphone, characteristics are that microphone is clipped in the neckline place, battery can be placed in the pocket or be clipped on the waistband, but battery case is placed on pocket or is clipped on the waistband very uncomfortablely, particularly summer, women teacher has put on skirt, battery does not just have the place to put, must be hand held in.On the other hand, in order to improve classroom efficiency, have a lot of teachers all to join electronic teacher pointer now, yet on the other hand take electronic teacher pointer, take battery case on the other hand, teacher can feel very ill, and when needing writing on the blackboard, seems inconvenient more.
Summary of the invention:
Task of the present utility model is to propose a kind of energy savings, and cost reduces, and teacher is saying class hour a kind of teaching aid more freely.Task of the present utility model is finished like this, it comprises electronic teacher pointer circuit circuit board, microphone circuit circuit board, electronic teacher pointer laser head, microphone, it is characterized in that: electronic teacher pointer laser head and microphone receiver are housed at the top of shrouding, the groove that electronic teacher pointer circuit circuit board and microphone circuit circuit board are housed is set in the shrouding, battery is equipped with in the bottom of shrouding, microphone cord is drawn from the lower right corner of shrouding, there is power switch the side of shrouding, and the back side of shrouding is provided with the battery cover and the clip of sealed cell.Electronic teacher pointer laser head and the series connection of electronic teacher pointer circuit circuit board, microphone receiver and the series connection of microphone circuit circuit board, on turn over, turn over down the pin that button, laser button are respectively electronic teacher pointer circuit circuit boards, electronic teacher pointer circuit circuit board and the microphone circuit circuit board is parallel to battery and switch is cascaded.The utility model has following effect: the utility model is that electronic teacher pointer and tie clip formula wireless microphone are united two into one by shrouding, common battery, and energy savings, cost reduces.Wireless microphone makes teacher's efficient of teaching higher, electronic teacher pointer operation courseware, teacher is taught more freely, and the clip of back can be placed on pocket or hang on the waist when not using electronic teacher pointer, and push-button design is hommization more, more convenient operation, electronic teacher pointer is integrated in the wireless microphone box, teacher is said class hour make things convenient for writing on the blackboard, also can be free movable in the classroom, freely control courseware, classroom efficiency is higher.
