Abstract
The utility model discloses a blackboard special for advanced mathematics function curve modeling. The blackboard comprises a blackboard body and a pedestal, and further comprises a projection cloth drum, a Bluetooth receiver, loudspeakers, and a glass plate which are all arranged on the blackboard body. A vertical column is arranged on the pedestal. The blackboard body is arranged on the vertical column. A storage cabinet is connected in the lower part of the blackboard body. The blackboard body is internally provided with a central processor. The Bluetooth receiver is connected with the central processor. The central processor is connected with the loudspeakers. A projector is arranged on the pedestal. The projection cloth drum is mounted in the upper part of the blackboard body and a piece of projection cloth is wound in the projection cloth drum. The blackboard is simple in structure, complete in function, wide in application scope, and long in service life; the blackboard is convenient to mount and use and easy to operate, and is safe and reliable; and the blackboard reduces the workload of teachers and increases the learning interest of students.
Description
Technical field
The utility model relates to a kind of higher mathematics function curve modeling special blackboard.
Background technology
The chapters and sections such as the computing of the limit in higher mathematics, dimensionless, Univariate Calculus and polynary infinitesimal calculus are all the most important things of this subject, for teacher, how to teach fast student by these emphasis, and apply in a flexible way after allowing student understand, it is teacher's difficult point, each teacher has the mode of giving lessons of oneself and the style of giving lessons, and some teachers are good at by teaching aid and give lessons, and some teachers allow student acquire etc. in the atmosphere of loosening in have a fine sense of humour mode.But existing teaching special blackboard can not meet people's demand, this has brought inconvenience to giving lessons of teacher.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of simple in structure, use, easy for installation, simple to operate, reduce teacher's workload, increase the interest of Students ' Learning, complete function, applied widely, long service life, has the higher mathematics function curve modeling special blackboard of safe and reliable effect.
For addressing the above problem, the utility model adopts following technical scheme: a kind of higher mathematics function curve modeling special blackboard, comprise blackboard body and base, and be arranged on the projection cloth cylinder on blackboard body, and be arranged on the Bluetooth Receiver on blackboard body, and be arranged on the loudspeaker on blackboard body, and be arranged on the glass plate on blackboard body, described base is provided with column, described blackboard body is arranged on column, described blackboard body is transferred and is connected with storage tank, in described blackboard body, be provided with central processing unit, described Bluetooth Receiver is connected with central processing unit, described central processing unit is connected with loudspeaker, described base is provided with projector, described projection cloth cylinder is arranged on blackboard body top, in described projection cloth cylinder, be wound with projection cloth, described loudspeaker is arranged on blackboard body both sides, described Bluetooth Receiver is arranged on blackboard bodies top.
As preferably, the setting corresponding with blackboard body of described projector, described base below is provided with universal wheel, and described universal wheel is provided with four.
As preferably, described column is hydraulically extensible bar.
When the utility model uses, teacher is facing to microphone speech, Bluetooth Receiver can receive the signal that microphone sends, after processing by central processing unit, inform student at speaker by the mode of voice, make rear row's classmate also can clearly hear teacher's teaching, and by set projector, the data that needs can be taught displays by the mode of projection, the mistaken ideas that teacher teaches are reduced, by set universal wheel, teacher is mobile blackboard arbitrarily, can be moved on one side in used time not.It is simple in structure, uses, easy for installation, simple to operate, has reduced teacher's workload, has increased the interest of Students ' Learning, complete function, and applied widely, long service life, has safe and reliable effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of higher mathematics function curve of the utility model modeling special blackboard;
Fig. 2 is the left view of a kind of higher mathematics function curve of the utility model modeling special blackboard.
Embodiment
Consult a kind of higher mathematics function curve modeling special blackboard shown in Fig. 1 and Fig. 2, comprise blackboard body 1 and base 2, and be arranged on the projection cloth cylinder 3 on blackboard body 1, and be arranged on the Bluetooth Receiver 4 on blackboard body 1, and be arranged on the loudspeaker 5 on blackboard body 1, and be arranged on the glass plate 6 on blackboard body 1, described base 2 is provided with column 7, described blackboard body 1 is arranged on column 7, described blackboard body 1 is transferred and is connected with storage tank 8, in described blackboard body 1, be provided with central processing unit 9, described Bluetooth Receiver 4 is connected with central processing unit 9, described central processing unit 9 is connected with loudspeaker 5, described base 2 is provided with projector 10, described projection cloth cylinder 3 is arranged on blackboard body 1 top, in described projection cloth cylinder 3, be wound with projection cloth 11, described loudspeaker 5 is arranged on blackboard body 1 both sides, described Bluetooth Receiver 4 is arranged on blackboard body 1 top.
