Abstract
The utility model discloses a movement demonstrating device of rotating objects in a sound field, which comprises loudspeakers, an organic glass container, a support frame and the rotating objects, wherein the loudspeakers are arranged at both sides of the organic glass container, the support frame is fixed in the organic glass container, and the rotating objects are respectively arranged at both sides of the support frame. The movement of the rotating objects can be visually seen through the movement demonstrating device, in addition, data obtained through measurement and molds are compared and are basically anastomotic, and the movement of the rotating objects can be explained in a quantitative way.
Description
Technical field
The utility model relates to a kind of teaching demonstration device, the apparatus for demonstrating of rotating object motion in particular a kind of sound field.
Background technology
At present, the device of relevant demonstration sound field generally can only be demonstrated static relatively phenomenons such as standing wave, for dynamic demonstration and calculating clocklike, does not also relate to.Demonstration research for sound field can only be qualitative, also do not accomplish quantitative demonstration.
The utility model content
The utility model purpose: the purpose of this utility model is to overcome the deficiencies in the prior art, and the apparatus for demonstrating of rotating object motion in a kind of sound field is provided, and can not only vividly demonstrate the motion of object in the sound field, can also provide the theoretical model quantitative interpretation.
Technical scheme: the utility model is achieved through the following technical solutions, the utility model comprises loudspeaker, organic glass container, support and gig, wherein: loudspeaker are located at the both sides of organic glass container, and support is fixed in the organic glass container, and gig is located at the both sides of support respectively.
Described support comprises base, vertical bar and horizon bar, and wherein: base is fixed in the organic glass container, and vertically bar is fixed on the base, and the top of vertical bar is located in the horizon bar activity, and the two ends of horizon bar are located in the gig activity.
Described organic glass container is an airtight container.
Described gig is recessed cup, and the longitudinal profile of recessed cup is semicircle or parabola shaped, measures the rotating speed and the sound field frequency relation of gig.
Described loudspeaker are provided with power instrument, can regulate the size and the frequency of sound field.
Described gig substitutes with energy sensor, measures the relation of same position place's amplitude and frequency.With gained data substitution theoretical derivation gained formula, can specifically verify.
Principle of work of the present utility model is: it is semicircle or parabola shaped being designed to the longitudinal profile with recessed glass, and when being placed in the airtight sound field, because sound field is propagated the vibration that drives air particles, gig can be subjected to clashing into repeatedly back and forth of air particles.Because the both sides of gig is different recessed to special shape, the difference of the action effect of the power that it will clash into because of the air particles vibration and rotating.Adopt power instrument can regulate the size and the frequency of sound field in the experiment, can measure the rotation situation of rotating object under different voltages, frequency.
Beneficial effect: the utility model can be seen the motion of gig intuitively, and the data that will measure gained contrast mutually with model, and is identical substantially, motion that can the quantitative interpretation gig.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Below embodiment of the present utility model is elaborated; present embodiment is being to implement under the prerequisite with technical solutions of the utility model; provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As shown in drawings, present embodiment comprises organic glass container 2, support and the gig 3 of loudspeaker 1, sealing, and wherein: loudspeaker 1 are located at the both sides of organic glass container 2, and support is fixed in the organic glass container 2, and gig 3 is located at the both sides of support respectively.
Loudspeaker 1 are embedded in organic glass container 2 both sides, add voltage after, can vibrate in container the sound field that forms characteristic frequency back and forth.
Described support comprises base 4, vertical bar 5 and horizon bar 6, and wherein: base 4 is fixed in the organic glass container 2, and vertically bar 5 is fixed on the base 4, and the top of vertical bar 5 is located in horizon bar 6 activities, and the two ends of horizon bar 6 are located in gig 3 activities.
Described gig 3 is recessed cups that plastics are made, and the longitudinal profile of recessed cup is semicircle or parabola shaped, measures the rotating speed and the sound field frequency relation of gig 3.
Described loudspeaker 1 are provided with power instrument, can regulate the size and the frequency of sound field.
Described gig 3 usefulness energy sensors substitute, and measure the relation of same position place's amplitude and frequency.With gained data substitution theoretical derivation gained formula, can specifically verify.
