Abstract
The present invention is a kind of sound transmission teaching aid, is characterized in, it comprises container, syringe and hummer, and the opening on described container top seals by plug, and the syringe needle of syringe inserts in the container by plug; Described hummer places in the container, connects outside the lead propelling container of hummer, and be provided with the power supply and the switch of connecting with hummer on lead.The present invention is a kind of teaching aid that is specifically designed to the airborne sound teaching.Use it the preschool child and the students of the junior years are carried out the natural science teaching, during use, open switch, start hummer, hummer sends the sound, firmly syringe is taken out outward, air in the container is taken out some, because the air minimizing, so the buzzer of hummer reduces, the student can the very lively air of perception intuitively transaudient ability, can attract student's interest and help improving students'ability for practice.
Description
Technical field
The present invention relates to a kind of teaching aid, particularly a kind of sound transmission teaching aid.
Background technology
In the prior art, when being carried out the natural science teaching, preschool child and the students of the junior years generally all do not have special teaching aid.Particularly to air can be transaudient teaching process in, only say that intuitive is relatively poor with teacher, student's cognitive ability can not obtain the performance.
Summary of the invention
Technical matters to be solved by this invention is at the deficiencies in the prior art, and a kind of simple in structure, lively sound transmission teaching aid intuitively is provided.
Technical matters to be solved by this invention is to realize by following technical scheme.The present invention is a kind of sound transmission teaching aid, is characterized in, it comprises container, syringe and hummer, and the opening on described container top seals by plug, and the syringe needle of syringe inserts in the container by plug; Described hummer places in the container, connects outside the lead propelling container of hummer, and be provided with the power supply and the switch of connecting with hummer on lead.
Compared with prior art, the present invention is a kind of teaching aid that is specifically designed to the airborne sound teaching.Use it the preschool child and the students of the junior years are carried out the natural science teaching, during use, open switch, start hummer, hummer sends the sound, firmly syringe is taken out outward, air in the container is taken out some, because the air minimizing, so the buzzer of hummer reduces, the student can the very lively air of perception intuitively transaudient ability, can attract student's interest and help improving students'ability for practice.
