Abstract
The utility model relates to a thunder and lightening phenomenon demonstration apparatus used in the teaching of the middle and primary schools. The outside of the top end of the box body is provided with a thunder switch, a lightening switch, a strobe light, a sound volume control switch and a loudspeaker; the lower ends of the power switch connected by conductors are welded on an efficiency module; a record switch and a play switch are welded on a record and play sound module; then a battery unit, the record and play sound module and a power amplifier module which are welded by conductors are put in the box body and are fixed at the box bottom by screws. Before using, the record and play sound module records thunder; then the play sound switch is pressed, and the play sound module is in play state; the thunder switch is pressed after the power supply being communicated; the thunder is repeated played; the lightning switch is pressed again; the strobe light can constantly send like lightning light which does not stop until the lightning switch is loosed, and the test is finished. The utility model solves the problem of lack of thunder and lightening phenomenon demonstration apparatus, and can be widely used in the teaching of the middle and primary schools.
Description
Technical field:
The utility model relates to " the atmospheric electrical phenomena demonstration device " of a kind of middle and primary schools teaching usefulness.
Background technology:
Thunder, electricity are the physical phenomenons that people often see at occurring in nature, in the middle school teaching process, can only describe in words in the past, there is not demonstration equipment, student's ratio is than indigestion, owing to economy, development of science and technology, the school that has buys multimedia computer and large screen projection equipment, demonstrates by computing machine now, but not general, and effect is very not remarkable.
The content of utility model:
In order to overcome the deficiencies in the prior art, the utility model provides a kind of atmospheric electrical phenomena demonstration device.This demonstration device is simple in structure, and volume is less, is convenient to teaching, and through on probation: teaching is directly perceived, image, and the student is convenient to understand, and teaching efficiency is good.
The technical scheme that its technical matters that solves the utility model adopts is: at first make rectangular casing with wooden or plastics, all be welded on the effect module after the lower end of thunder switch, lightning switch, stroboscopic lamp, volume control switch, loudspeaker, power switch being connected with lead again.Again the upper end of thunder switch, lightning switch, stroboscopic lamp, volume control switch is fixed on the tip exterior of casing with screw or nut, loudspeaker is fixed on taking back on the plate of casing the inside, medium position with screw, then recording switch, playback switch is welded on the recording playback sound module.Electric battery, recording playback sound module and power amplifier module being packed into after with wire bonds, the back is fixed on bottom half with screw in the casing again.Record thunder with recording playback sound module before use, clicking playback switch then makes recording playback sound module be in tone playing state, behind power connection, click the thunder switch, meeting repeat playing thunder, after clicking the lightning switch again, stroboscopic lamp will not stop sends as fulgurous light and unclamps the lightning switch and just can stop up to having tested.
The beneficial effects of the utility model are, simple in structure, volume is little, are easy to carry, and the demonstration effect is true to nature, are convenient to the student and understand, and improve study and teaching efficiency.
Description of drawings:
Fig. 1 is the utility model one-piece construction synoptic diagram.
Fig. 2 is the utility model circuit diagram.
Among the figure 1, volume control switch, 2, lead, 3, casing, 4, power amplifier module, 5, power switch, 6, recording switch, 7, playback switch, 8, recording playback sound module, 9, electric battery, 10, loudspeaker, 11, the thunder switch, 12, the lightning switch, 13, stroboscopic lamp.
Embodiment:
In Fig. 1, at first use the casing 3 of wooden or plastic production rectangularity, lower end and the power switch 5 with thunder switch 11, lightning switch 12, stroboscopic lamp 13, volume control switch 1, loudspeaker 10 is welded on the effect module 4 again.Again the upper end of thunder switch 11, lightning switch 12, stroboscopic lamp 13, volume control switch 1 is fixed on the tip exterior of casing 3 with screw or nut, loudspeaker 10 usefulness screws are fixed on panel in the casing take back middle part or medium position.Then recording switch 6, playback switch 7 are welded on the recording playback sound module 8.Again back in the casing 3 of packing into after electric battery 9, recording playback sound module 8 and 2 welding of power amplifier module 4 usefulness leads is fixed on the bottom of casing 3 with screw.Recording playback sound module 8 records thunder before use, click playback switch 7 then, make recording playback sound module 8 be in tone playing state, behind power connection, click thunder switch 11 and can insert thunder repeatedly, what click that lightning switch 12 back stroboscopic lamps 13 will not stop sends the fulgurous light of picture up to having tested again, and unclamps lightning switch 12 and just can stop.
In Fig. 2, volume control switch 1, power switch 5, loudspeaker 10, thunder switch 11, lightning switch 12, stroboscopic lamp switch 13, battery pack 9, playback switch 7, recording switch 6 are the circuit connection.
