超声地形障碍检出系统换能器的研制
Study on the Ultrasonic Transducer Used in the System For Detecting and Sending the Obstacles
摘要
介绍适用于超声地形障碍检出传感系统，向空气辐射的弯曲振动型超声换能器的研制.该换能器结构简单，制作方便，可在空气介质中产生高强度的超声波和良好的方向性 This paper introduces a kind of ultrasonic transducer which emits the sound wave to the air in the style of Flexuous vibration and is Fit to be used in the system For detecting and sensing the obstacles.The transducer with a simple structure is easy to be made and can produce strong ultrasonic waves in the air with a good directional character.
