The ultrasonic guide alarming device of this creation is a ring structure body, is at least provided with a vibrator on this ring structure body of what. This ring structure system with electrical connection is to another ultrasonic sensors, the ultrasonic sensors detect the echo of the emitted wave frequency of ultrasonic emitter by ultrasonic receiver, the operation echo time simultaneously comes alarm obstruction object space position and distance with the vibrator on ring structure body, and vibrator is to issue two-part vibration strong or weak and time of vibration length, come the distance and orientation of alarm obstruction object, preceding object object is detected in order to reaching, helping what prevents blind person from colliding injured safety when ensureing that blind person walks.本創作之超音波導盲警示裝置，為一環形結構體，其至少於此環形結構體上設置有一振動器。此環形結構體係以電性連結至另一超音波感測裝置，該超音波感測裝置藉由超音波接收器偵測到超音波發射器所發射波頻的回波，運算回波時間並以環形結構體上的振動器來警示障礙物方位及距離，而振動器是以發出兩段式振動強弱與振動時間長度，來警示障礙物的距離遠近與方位，俾達偵測前方障礙物體，有助於防止盲者碰撞受傷，以保障盲者行走時的安全。
