Phenomenon acquires scientific knowledge, does not accomplish to teach through lively activities.
Utility model content
The utility model will solve the above-mentioned problems of the prior art, provide a kind of sound floating didactical doll, solve
The problem of the difference of traditional toy science popularization at present, meets the needs of of teaching through lively activities.
The utility model solves the technical solution of its technical problem use: this sound floats didactical doll, including positioning
Plate, positioning plate are respectively fixed with the speaker of hand generator and loudspeaker towards surface on front, and hand generator and speaker exist
Back connection is positioned, is equipped with one group of transparent pipe being vertically arranged, transparent pipe top closure and bottom end right above the loudspeaker of speaker
Outlet is covered with elastic membrane, and the floating material of lightweight is equipped in transparent pipe.After being arranged in this way, hand generator power generation makes speaker work
Make, speaker makes a sound, and the propagation of sound is by air along transparent pipe direction Vibration propagation, and air vibration self-assembling formation is from lower past
On air-flow, air-flow drives the floating material of lightweight to float in transparent pipe, and the transparent attribute of transparent pipe is convenient directly to be seen from outside
The floating state of floating material is examined, the intuitive principle and feature for understanding sound transmission is taught through lively activities.
It is horizontal between transparent pipe and speaker as a further improvement of the utility model, to have soundproof plate, run through on soundproof plate
Equipped with up-small and down-big bundle holes, bundle holes are aligned setting with transparent pipe coaxial line.Soundproof plate can effectively prevent sound outside
Side radiation diffusion, allows major part air-flow caused by acoustical vibration by bundle holes, and the up-small and down-big structure of bundle holes is conducive to add
The flow velocity of air blast is easier the more powerful floating material floating of air-flow, reduces the work load of speaker.
Transparent pipe includes the first transparent pipe and the second transparent pipe as a further improvement of the utility model, and first is transparent
Floating material in pipe is hollow ball, and the floating material in the second transparent pipe is one group of plastic grain.Hollow ball inner hollow can pole
Mitigate weight in big degree, utilizes float；Plastic grain floats under airflow function, increases the layer of floating material float
The characteristics of secondary sense, more intuitive understanding sound transmits.
It is equipped with close to top in the first transparent pipe and is connected with hand generator as a further improvement of the utility model,
Electromagnet, electromagnet bottom extremity are directed at hollow ball, are embedded with magnetic embedded chip in hollow ball on cross section.Hand generator
Electromagnet band is magnetic after power generation, and during hollow ball floats up, embedded chip is extremely repelled each other with electromagnet or attracting, drive
Hollow ball makes more complicated movement in transparent pipe.
LED light is equipped in transparent pipe as a further improvement of the utility model, LED light is connected with hand generator, fixed
Position plate front is equipped with control button, and control button is made of flash button and color button, leads between control button and LED light
Cross single-chip microcontroller connection.Hand generator powers and shines to LED light, and control button is used to control the illumination effect of LED light, specifically
The flicker frequency of LED light is controlled by flash button, and color button then can control the color change of LED light, such LED
The transformation of lamp is more abundant, and light does not stop the richer visual impact of transformation, externally gets up more attractive.
Positioning plate front is equipped with the protective cover for covering speaker as a further improvement of the utility model, sets in speaker
There is control to play the single-chip microcontroller of music.Protective cover avoids speaker by the destruction of the interference of extraneous factor, list for protecting speaker
Piece machine controls speaker and plays music, enhances the attraction with child.
Positioning plate dorsal edge is evenly equipped with one group of support leg, support leg height as a further improvement of the utility model,
Higher than positioning plate behind protruding parts height.Support leg can play a supporting role when laying flat, can also be independent when placing vertically
Connecting pin as wall hanging, it is contemplated that positioning plate has some positions outstanding behind, and support leg can play the high positioning plate of frame
Effect, avoid positioning plate from having protruding parts behind and directly contacted with bottom surface, protection positioning plate have protruding parts behind.
The utility model has the advantages that: the utility model it is structurally reasonable, compact, by hand generator power generation make
Speaker plays music, using the use of sound being that the principle rotated by air amplifies oscillation intensity by bundle holes, is formed upward
Air draught and finally blowing afloat floating material floats it in transparent pipe, intuitively allow child understand sound transmission original
Reason, cooperated with LED lamp increase the visual effect in transparent pipe, further increase attraction, have the effect of teaching through lively activities, suitable for pushing away
Extensively.
