Abstract

The invention discloses a blind orientation training device for simulated outdoor danger avoidance based on Doppler effects, which relates to the technical field of blind orientation training. The blind orientation training device for simulated outdoor danger avoidance based on Doppler effects comprises a bottom plate, and is characterized in that the middle part of the top part of the bottom plate is fixedly connected with two fixing plates; the opposite sides of the two fixing plates are movably connected with the left end and the right end of a roller; the roller is sleeved with a belt; a supporting plate is arranged in front of the belt; and the bottom part of the supporting plate is fixedly connected with the top part of the bottom plate. According to the blind orientation training device for simulated outdoor danger avoidance based on Doppler effects disclosed in the invention, through arrangement of a training simulation mechanism and matched arrangement of a second rotary motor, a horizontal rotation rod and a connection rod, the perception sensibility of the blind towards surrounding sounds can be effectively enhanced based on the Doppler effects, and the outdoor danger avoidance reaction capability of the blind can be improved.

Description

technical field [0001] The invention relates to the technical field of orientation training for the blind, in particular to an orientation training device for the blind who simulates outdoor danger avoidance based on the Doppler effect. Background technique [0002] When a blind person walks outdoors, the brain can establish a temporary neural connection between the sound and specific things by locating and locating the sound source based on the difference in the intensity of the sound reaching the two ears and the difference in the time when the sound reaches the two ears, and the individual can learn through hearing. orientation. [0003] According to the principle of the Doppler effect, when an object makes the same sound, the closer the distance is, the louder it is, and the farther the distance is, the smaller it is. Therefore, individuals can judge the distance of an object by the size of the sound. The time difference can judge the direction of the sound. By turning ...
