Abstract
The utility model discloses an acoustic levitation device which comprises a first transparent housing (1) and a second transparent housing (5). One end of the first transparent housing (1) is connected with one end of the second transparent housing (5). A foam ball (2) is disposed inside the first transparent housing (1). A circuit board (4) is arranged inside the second transparent housing (5). The circuit board (4) is connected with a horn (3), and the opening end of the horn (3) corresponds to one end of the first transparent housing (1). The acoustic levitation device is also equipped with a volume adjusting button and an audio adjusting button. The beneficial effects of the utility model are that the acoustic levitation device is simple in structure and small in size, is easy to be transported, can serve as an instrument for research of the technology of an acoustic levitation device in classroom teaching, and also can be used as a common toy.
Description
Technical field
The utility model relates to a kind of qin, particularly a kind of sound suspending device.
Background technology
Sound suspending device is a kind of nonlinear effect under the high sound intensity condition; The sound suspending device principle is to utilize suspending power that the interaction of sound standing wave and object produces vertical direction to overcome the weight of object, and the detent force that produces horizontal direction simultaneously is fixed in acoustic pressure node place with object.The experimental facilities of existing research sound suspending device technology is too complicated, and being only limited to general large-scale experiment has, and is difficult to use as general classroom experiment equipment.
Summary of the invention
To the shortcoming of traditional qin, the utility model provides a kind of novel sound suspending device.
To achieve these goals, the measure taked of the utility model:
Sound suspending device comprises transparent housing one and transparent housing two, and an end of said transparent housing one links to each other with an end of transparent housing two, is provided with foam ball in the said transparent housing one; Be provided with circuit board in the said transparent housing two, said circuit board links to each other with loudspeaker, and the openend of loudspeaker is corresponding with an end of transparent housing one; Also be provided with volume and regulate button and audio frequency adjusting button.
The beneficial effect of the utility model: the utility model is simple in structure, and volume is little, is easy to carrying, can be used as the equipment of research sound suspending device technology in the classroom instruction, also can be used as general toy and uses.
Description of drawings
Fig. 1, the structural representation of the utility model.
Embodiment
Sound suspending device comprises transparent housing 1 and transparent housing 25, and an end of said transparent housing 1 links to each other with an end of transparent housing 25, is provided with foam ball 2 in the said transparent housing 1; Be provided with circuit board 4 in the said transparent housing 25, said circuit board 4 and loudspeaker
3 link to each other, and the openend of loudspeaker 3 is corresponding with an end of transparent housing 1; Also be provided with volume and regulate button and audio frequency adjusting button.
Sound suspending device is a kind of nonlinear effect under the high sound intensity condition; The sound suspending device principle is to utilize suspending power that the interaction of sound standing wave and object produces vertical direction to overcome the weight of object, and the detent force that produces horizontal direction simultaneously is fixed in acoustic pressure node place with object.The sound suspending device technology is divided into two kinds of triple axle and single axles; The former is that three orthogonal directionss excite the position of a row standing wave with the control object respectively in the space; The latter only produces a row standing wave at vertical direction, and its suspension Ding Heli is provided by the sound field of the certain pattern that cylindrical cavity excited.The sound suspending device technology is that ground and space condition are realized one of gordian technique that the no container of material is handled down; With the electromagnetic suspension compared with techniques; The restriction whether it is not conducted electricity by material, and suspend and heating control respectively, thereby can solidify in order to research nonmetallic materials and the metallurgical no container of low melting point.
The utility model frequency range is: 10Hz-1kHz; Output power is: 0.5W-3W: use power supply direct current 12V.Can earlier volume adjustment knob be transferred to maximum in use, again the frequency adjustment knob be regulated from small to large, in adjustment process, observe the suspension situation (we can be observed bead and when a certain frequency, can suspend) of foam bead; Also can earlier minimum be arrived in volume adjusting and frequency adjustment in use, again volume is transferred to the centre position, then frequency adjustment regulated from small to large (watching whole process bead whether can suspend).
The beneficial effect of the utility model: the utility model is simple in structure, and volume is little, is easy to carrying, can be used as the equipment of research sound suspending device technology in the classroom instruction, also can be used as general toy and uses.
Those skilled in the art's simple change and replacement all are within the protection domain of the utility model in this area.
Claims (2)
1. sound suspending device comprises transparent housing one (1) and transparent housing two (5), and an end of said transparent housing one (1) links to each other with an end of transparent housing two (5), it is characterized in that: be provided with foam ball (2) in the said transparent housing one (1); Be provided with circuit board (4) in the said transparent housing two (5), said circuit board (4) links to each other with loudspeaker (3), and the openend of loudspeaker (3) is corresponding with an end of transparent housing one (1).
