Abstract
The utility model discloses a moving coil type loudspeaker principle demonstration board, which comprises a semi-ring alternating current converter, a moving coil type electromagnetic coil, a paper basin of a loudspeaker, a rocking handle, the loudspeaker, a music circuit board and a battery, wherein a permanent magnet is arranged in the moving coil type electromagnetic coil, the paper basin of the loudspeaker is fixed on the moving coil type electromagnetic coil with the permanent magnet being arranged at the inside, the moving coil type electromagnetic coil with the permanent magnet being arranged at the inside is connected with the semi-ring alternating current converter, the rocking handle is arranged on the semi-ring alternating current converter, and the music circuit board is connected with the semi-ring alternating current converter and is conducted with the loudspeaker through the battery. The moving coil type loudspeaker principle demonstration board has an ingenious design and is simple to operate, the perceptual knowledge of students on teaching contents can be deepened, and the students can understand and remember the contents.
Description
Technical field
The utility model relates to a kind of coil-moving speaker principle demonstration plate, particularly the coil-moving speaker principle demonstration plate about using in teaching.
Background technology
As everyone knows, loudspeaker seals, and its inner structure can't see, and is very difficult when giving student explain, is not easy to make clear, and the student understands very difficult.In teaching, the student is easier to be understood in order to make, and can understand and remember, just need be equipped with the educational aid that is easily understood to demonstrate.
Summary of the invention
Technical problem to be solved in the utility model is, overcome the shortcoming that prior art exists, a kind of coil-moving speaker principle demonstration plate is provided, coil-moving speaker principle object simulating is fixed on the substrate, reach that the student is seen easily is clear, and the purpose that can understand and remember.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of coil-moving speaker principle demonstration plate, it is characterized in that, comprise semi-ring alternation electric transducer, the moving-coil type solenoid of band built-in permanent magnets, the cone of loudspeaker; rocking handle; loudspeaker, music circuit plate and battery, the cone of loudspeaker are fixed on the moving-coil type solenoid of band built-in permanent magnets; the moving-coil type solenoid of band built-in permanent magnets connects semi-ring alternation electric transducer; semi-ring alternation electric transducer is provided with rocking handle, and the music circuit plate connects semi-ring alternation electric transducer, and connect by battery with loudspeaker.
The beneficial effects of the utility model are: this teaching aid design is ingenious, simple to operate, and the simulation of coil-moving speaker principle is fixed on the substrate, the demonstration effect is obvious in teaching practice, principle demonstration is clear, can deepen the perceptual knowledge of student to the content of courses, and can understand and remember.
Description of drawings
Fig. 1 is a coil-moving speaker principle demonstration plate synoptic diagram.
Among the figure:
The moving-coil type solenoid of 1 semi-ring alternation electric transducer, 2 band built-in permanent magnets
Cone 4 rocking handles of 3 loudspeakers
5 loudspeakers, 6 music circuit plates
7 batteries
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail: coil-moving speaker principle demonstration plate, as shown in the figure, comprise semi-ring alternation electric transducer, the moving-coil type solenoid of band built-in permanent magnets, the cone of loudspeaker; rocking handle; loudspeaker; music circuit plate and battery; the cone of loudspeaker is fixed on the moving-coil type solenoid of band built-in permanent magnets, the moving-coil type solenoid of band built-in permanent magnets connects semi-ring alternation electric transducer, and semi-ring alternation electric transducer is provided with rocking handle; the music circuit plate connects semi-ring alternation electric transducer, and connects by battery with loudspeaker.
In presentation process, at first open the switch that leads to loudspeaker, loudspeaker begins playing back music, open the switch that leads to the moving-coil type solenoid of being with built-in permanent magnets then, shake semi-ring alternation electric transducer with handle, the moving-coil type solenoid of band built-in permanent magnets is vibration back and forth constantly just, drives the also vibration back and forth of cone of loudspeaker, so the cone of loudspeaker is just sounded.Design of the present utility model is ingenious, and is simple to operate, can deepen the perceptual knowledge of student to the content of courses, and can understand and remember.
