Abstract
The utility model discloses a teaching combination board, comprising a frame, a first writing board, and an electronic whiteboard. The first writing board is disposed on a front side of the frame. The electronic whiteboard is embedded in the first writing board or is arranged side by side with the first writing board. The frame comprises an upper frame, a lower frame, a left frame, and a right frame. The left frame and the right frame are respectively provided with a loudspeaker box. The teaching combination board is advantaged in that the left frame and the right frame are respectively provided with the loudspeaker box inside, the loudspeaker boxes are relatively dispersed in the frame, so that spread range of voice is enlarged and amplification effect is good.
Description
Technical field
The utility model relates to a kind of board of education, especially relates to a kind of teaching group plywood.
Background technology
Existing teaching group plywood has generally comprised framework, computer, clipboard and electronic whiteboard.Wherein clipboard is fixedly installed on the front side of framework, and electronic whiteboard embeds in clipboard or is arranged side by side with clipboard, and computer is connected with electronic whiteboard.Existing teaching group plywood generally is respectively arranged with built-in speaker in the both sides of electronic whiteboard, causes thus teacher to say being sitting in class hour electronic whiteboard student's on one side audibility relatively good, and it is bad to be sitting in clipboard student's on one side audibility.
Summary of the invention
Technical problem to be solved in the utility model is to provide the good teaching group's plywood of a kind of amplifying effect.
The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of teaching group plywood, comprise framework, the first clipboard and electronic whiteboard, described the first clipboard is arranged on the front side of described framework, described electronic whiteboard is embedded in described the first clipboard or with described the first clipboard and is arranged side by side, described framework comprises upper side frame, lower frame, left frame and left frame, is respectively arranged with audio amplifier in described left frame and described left frame.
Also be provided with audio amplifier in described upper side frame and described lower frame.
Described audio amplifier is the double horn audio amplifier.
Described audio amplifier is four Horn loudspeaker boxs.
Form chamber between described framework, described the first clipboard and described electronic whiteboard, be provided with computer in described chamber, described computer be connected electronic whiteboard and connect.
Described electronic whiteboard is infrared electronic blank, induction electronic whiteboard, ultrasonic electronic blank or optical electron blank.
The front side of described the first clipboard is provided with the second clipboard, the top and bottom of described the second clipboard are fixedly installed respectively pulley, be provided with the sliding rail that coordinates with described pulley on described upper side frame and described lower frame, described pulley can move left and right in described sliding rail.
Compared with prior art, the utility model has the advantage of that framework comprises upper side frame, lower frame, left frame and left frame, be respectively arranged with audio amplifier in left frame and left frame, in framework, audio amplifier relatively disperses, and has enlarged the spread scope of sound, and amplifying effect is good;
When the front side of the first clipboard was provided with the second clipboard, when not using electronic whiteboard, write the front side that the second clipboard can be moved to electronic whiteboard.
