One concrete application of the present embodiment are as follows: starting supersonic generator 11 operates, and supersonic generator 11 is operating
During can disseminate ultrasonic wave around, to effectively be worked, close to the sound insulation of supersonic generator 11 in cabinet 1
Plate 22 can stop to the ultrasonic wave come is propagated through, and the first reflection unit 23 and the second reflection unit on soundproof plate 22
24 can effectively reflect ultrasonic wave, so that soundproof plate 22 is strong about the ultrasonic wave of the plane of symmetry of supersonic generator 11
Degree is bigger, keeps its effect more preferable, while also tentatively blocking the propagation of the ultrasonic wave in 22 direction of soundproof plate, through first layer sound insulation
The ultrasonic wave of plate 22 can enter in abatvoix 21, and the second slot 25 in abatvoix 21 can be reflected ultrasonic wave constantly, thus plus
Fast absorption of the abatvoix 21 to ultrasonic wave, so that the ultrasonic intensity in 22 direction of soundproof plate is smaller, after being absorbed by abatvoix 21
Ultrasonic wave using second layer soundproof plate 22 reflection and blocking so that the ultrasonic wave on 22 direction of soundproof plate is effective
It stops, to will not influence the normal use of other equipment on 22 direction of soundproof plate.
One group of refrigerator 12 can carry out circularly cooling processing to the coolant liquid in the first tube body 13 and the second tube body 15, thus
So that the coolant liquid in the first tube body 13 and the second tube body 15 remains lower temperature, recycle air blower 16 by the external world
Wind is blown into cabinet 1 along air-out groove 18 and bellows 19, and wind is after one group of second tube body 15, and temperature reduces, thus to ultrasound
Wave producer 11 carries out effective cooling processing, because cold airflow specific heat current density is big, the wind blown into along bellows 19
The heat that supersonic generator 11 generates can be pushed up, and drive three using the motor 7 being arranged above supersonic generator 11
A flabellum 9 rotates, to heat is timely discharged, so that the cooling effect of supersonic generator 11 is more preferably.
Support plate 2 is relatively thin steel plate structure, has certain elasticity, and in one layer of rubber of the Surface mulch of support plate 2
Glue-line so that cabinet 1 can be by effective damping when shaking, while being equipped with spring 3 at the concave point of support plate 2, so that
When cabinet 1 is hit by the external world, damping processing also can be effectively carried out, to protect the peace of supersonic generator 11 in cabinet 1
Entirely, and support plate 2 is serpentine configuration so that the support performance of support plate 2 is more stable, while support plate 2 also by cabinet 1 with
Ground is detached from, so that cabinet 1 not will receive the erosion of ground moisture, protects the normal use of cabinet 1.
