Abstract
The utility model discloses a doppler effect principle presentation device, the power distribution box comprises a box body, the box up end be the transparent panel, the box in be equipped with the lead screw, lead screw one end is equipped with step motor, is equipped with the fixed plate on the lead screw, the fixed plate lower extreme is equipped with the sliding block, the sliding block overlap on the lead screw with lead screw screw -thread fit, the fixed plate on be equipped with LED lamp display screen, the pointolite of LED lamp display screen constitute by multiunit LED lamp, LED lamp controller control LED lamp shows for the sound wave appearance. The utility model discloses a LED lamp display screen and is moved together through moving fixed slab band, be sound wave appearance through control through LED lamp briglt display in the LED lamp display screen at the in -process of motion, carries out vivid performance with doppler effect to make the audio -visual understanding doppler effect of participant is this scientific reason of how forming actually.
Description
Technical field
The utility model relates to the principles of science presentation device technical field, is specifically related to a kind of Doppler effect presentation device of theory.
Background technology
In daily life, people can have this experience: when one arranges the train of the steam whistle that rings through certain observer, he can find that the tone of train steam whistle is by high step-down.Why can there is this phenomenon? this is because the height of tone is determined by the difference of acoustic vibration frequency, if frequency is high, tone sounds just high; Otherwise tone sounds just low.This phenomenon is called Doppler effect.Existing owing to lacking experimental tool, still actually the understanding Doppler effect that a lot of people can not be real how to be formed with the figure of Doppler effect.
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of Doppler effect presentation device of theory, overcome the deficiencies in the prior art, reasonable in design, compact conformation, by LED display screen by mobile fixed head with moving together, in the process of motion, by controlling, in by LED display screen, LED is bright is shown as sound wave profile, Doppler effect is carried out the performance of image, thus to make participant get information about Doppler effect be this science reason how to be formed actually.
Technical problem to be solved in the utility model can be come to be realize by the following technical programs:
A kind of Doppler effect presentation device of theory, comprise casing, described casing upper surface is transparent panel, is provided with screw mandrel in described casing, and screw mandrel one end is provided with stepper motor, screw mandrel is provided with fixed head, fixed head lower end is provided with sliding shoe, and sliding shoe is placed on leading screw and coordinates with wire rod thread, and described fixed head is provided with LED display screen, the pointolite of described LED display screen forms by organizing LED more, and LED controller controls LED and is shown as sound wave profile.
Described casing centre position is provided with sound simulator, and sound simulator is connected with earphone, carries out simulation loud and in a low voice, carry out step raising experience effect by sound simulator according to the distance of experiencer.
Experience personnel standing place is provided with outside described casing centre position.
Compared with prior art, the beneficial effects of the utility model are:
The utility model by LED display screen by mobile fixed head with moving together, in the process of motion, by controlling, in by LED display screen, LED is bright is shown as sound wave profile, Doppler effect is carried out the performance of image, thus to make participant get information about Doppler effect be this science reason how to be formed actually.
Accompanying drawing explanation
Fig. 1 is the utility model plan structure schematic diagram;
Fig. 2 is the utility model side structure schematic diagram.
Embodiment
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of Doppler effect presentation device of theory, comprise casing 1, described casing 1 upper surface is transparent panel 101, screw mandrel 2 is provided with in described casing, screw mandrel 2 one end is provided with stepper motor 3, screw mandrel 2 is provided with fixed head 4, fixed head 4 lower end is provided with sliding shoe 5, sliding shoe 5 is placed on leading screw 2 and coordinates with wire rod thread, described fixed head 4 is provided with LED display screen 6, the pointolite of described LED display screen 6 forms by organizing LED 7 more, LED controller controls LED and is shown as sound wave profile, experience personnel standing place 8 is provided with outside described casing centre position, described casing 1 centre position is provided with sound simulator 9, sound simulator is connected with earphone 10, simulation is carried out according to the distance of experiencer loud and in a low voice by sound simulator, carry out step and improve experience effect, by LED display screen by mobile fixed head with moving together, in the process of motion, by controlling, in by LED display screen, LED is bright is shown as sound wave profile, Doppler effect is carried out the performance of image, thus to make participant get information about Doppler effect be this science reason how to be formed actually.
It should be noted that, in this article, such as term " comprises ", " comprising " or its any other variant are intended to contain comprising of nonexcludability, thus make to comprise the process of a series of key element, method, article or equipment and not only comprise those key elements, but also comprise other key elements clearly do not listed, or also comprise by the intrinsic key element of this process, method, article or equipment.When not more restrictions, the key element limited by statement " comprising ... ", and be not precluded within process, method, article or the equipment comprising described key element and also there is other identical element.
Above embodiment only in order to the technical solution of the utility model to be described, is not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
