Abstract

The invention relate to a householdgoods for blindmen, in particular to a voice walking stick with voice hint for blindmen, which is characterized in that the microtreater is connected with sensing head emitting supersonic wave through boosted circuit to output working signal emitted by supersonic wave sensing head, which is connected with input end of comparator through amplifier and band filter at the same time, the sensibility regulator controlled by microtreater in host machine is connected with the other end of comparator, the output end of comparator is connected with microtreater, and the microtreater is connected with ear phone through voice memory and energy amplification circuit. The distance between hand stick and obstacle can be detected by voice energy amplifier and distinguish the distance with tone of voice, the further of the distance, the lower and slower of the tone of alarm; and the nearer of distance, the higher and faster of the tone of alarm, by means of which to alarm the blind.

Description

technical field [0001] The invention relates to daily necessities for the blind, in particular to an anti-collision cane for the blind with voice prompts for distance. Background technique: [0002] In the prior art, the cane of the blind generally adopts a wooden stick for exploring the road and moves forward by feeling by touching the ground. Although the existing blind road guides the way, there are often obstacles on the blind road, and it is difficult for the blind to clearly judge the location of the obstacle. distance. Contents of the invention [0003] In order to overcome the defects in the prior art, the invention provides a distance voice to instruct blind people to avoid obstacles and avoid collisions. [0004] The technical solution adopted by the present invention to solve the technical problem is: a voice anti-collision cane for the blind, including a host, an ultrasonic transmitting and receiving sensor, and an earphone. It is characterized in that the hos...
