Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, and the present invention includes but not limited to the following embodiments.

[0028] The invention provides a scientific research and experimental equipment capable of meeting the requirements of different physical experiment environments, and at the same time can arbitrarily select different types of horns according to different samples to be suspended, and provides new experimental observation methods and ideas. According to the principle of ultrasonic levitation, and the relationship between the propagation speed of ultrasonic waves and the density of the medium, (V is the velocity of the sound wave in the gas, k is the adiabatic coefficient of the gas, p is the gas pressure, and d is the gas density). Therefore, it is determined that changes in the physical experimental environment such as temperature, humidity, and pressure will have a certain ...

Abstract

The invention provides a multiple physical environment controllable acoustic levitation experiment apparatus. A support base seat and a transparent pressure resistance cover are connected to form an enclosed cavity; an electric elevating platform is mounted on the support base seat, a sound reflecting end on the electric elevating platform is driven via an electric motor to move up and down, an energy transducer is fixed on the support base seat via support rods, and a supersonic generator is connected with the energy transducer; that one of a step-shaped amplitude transforming rod, a conicalamplitude transforming rod and an exponential type amplitude transforming rod shares the same axis with an output end of the energy transducer can be guaranteed via a lower end of the energy transducer via movement of a converter; a sound emitting end of the amplitude transforming rod is right opposite to the sound reflecting end; a humidifier, a heating pipe, an air pressure gauge, a temperaturesensor and a humidity sensor are mounted in the cavity; the cavity is also provided with a vent hole communicated with the outside or a gas transmission device. Via the multiple physical environment controllable acoustic levitation experiment apparatus, requirements for different physical experiments can be met, and different types of amplitude transforming rods can be chosen at will according todifferent samples to be levitated.

Description

technical field [0001] The invention belongs to the power ultrasonic non-contact technology, and relates to a multi-horn automatic acoustic levitation scientific research experimental device with controllable experimental temperature, humidity and pressure. Background technique [0002] With the rapid development of the material industry, the requirements for the physical environment for the preparation of new materials are also getting higher and higher. All-round scientific research experiments often require observation of experimental objects in different physical environments. The emergence of acoustic levitation technology and its rapid development in recent years have provided new ideas and possibilities for the above-mentioned experimental environment and measurement. [0003] Acoustic levitation is an emerging technology that uses the sound radiation force generated in the strong standing wave sound field to balance the gravity of the suspended sample in a gravity o...
