Abstract
A stereo ultrasonic blind-aid can assist the blind by sensing and gaining the solid profiles of the environmental object exceeding the length of the blind wand, and facilitating the blind's going outside. This utility model comprises a control switch, a supersonic generator, and a earphone with which an acoustic generator is provided. The utility model is characterized in that two supersonic receivers arranged to the left-right ear packages with which filter, converter and amplifier arranged within the casing are equipped. Furthermore, the filter, converter and amplifier connect to the terminal end of the two supersonic receivers, as well as the amplifier output connects separately with two acoustic generators via wires. With features of simple structure, low cost and convenient usage, this utility model shows the advantage of helping the blind man of sensing and gaining the solid profiles of the environmental object with hearing to orient his way, consequently greatly facilitating blind man's daily life.
Description
Technical field
This utility model belongs to blind person's articles for use, particularly a kind of Sterosonic ultrasonic blindman-helping tool.
Background technology
The general blind man's stick that the uses when blind person goes out, the object around blind man's stick can only be felt in the scope that blind man's stick length can reach does not have stereo profile to the object of feeling, makes blind person's extremely inconvenience of trip, brings difficulty for blind person's daily life.
Summary of the invention
The purpose of this utility model is to solve the weak point that prior art exists, provide a kind of blind person of making to perceive the solid space profile of object on every side, help the identification of blind person, thereby greatly make things convenient for the Sterosonic ultrasonic blindman-helping tool of blind person's daily life the walking orientation.
This utility model is achieved in that it has a gauge tap 1, supersonic generator 2 and earphone 13, left side at earphone 13, be respectively equipped with audio frequency acoustical generator 11 and 12 in the auris dextra bag, its special character is: the ultrasonic blind person aid device of this solid also is provided with two ultrasonic receivers 3 and 4, outfan in ultrasonic receiver 3 and 4 is connected to respectively and is used to filter clutter and keeps wave filter 5 and 6 with frequency ultrasonic, be used for the ultrasonic signal frequency conversion that will receive and delay time producing the converter 7 and 8 of audio signal, amplifier 9 and 10, described ultrasonic receiver 3 and 4 is separately positioned on the left side of earphone 13, in the auris dextra bag, and amplifier 9 is connected with 12 with audio frequency acoustical generator 11 by lead respectively with 10 outfans, described wave filter 5 and 6, converter 7 and 8 and amplifier 9 and 10 be located in the machine box 14.
The utility model has the advantages that: can make the solid space profile of blind person, help the identification of blind person, thereby greatly make things convenient for blind person's daily life the walking orientation by the object of audition around perceiving, and simple in structure, cost is low, and is easy to use.
The drawing explanation:
Fig. 1 is a circuit block diagram of the present utility model;
Fig. 2 is the structural representation of this utility model earphone;
Fig. 3 is that the A of Fig. 2 is to partial view.
Among the figure: gauge tap 1, supersonic generator 2, ultrasonic receiver 3, ultrasonic receiver 4, wave filter 5, wave filter 6, converter 7, converter 8, amplifier 9, amplifier 10, audio frequency acoustical generator 11, audio frequency acoustical generator 12, earphone 13, machine box 14.
The specific embodiment:
As shown in the figure, this utility model has a gauge tap 1, supersonic generator 2 and earphone 13, left side at earphone 13, be respectively equipped with audio frequency acoustical generator 11 and 12 in the auris dextra bag, the ultrasonic blind person aid device of this solid also is provided with two ultrasonic receivers 3 and 4, outfan in ultrasonic receiver 3 and 4 is connected to respectively and is used to filter clutter and keeps wave filter 5 and 6 with frequency ultrasonic, the ultrasonic signal frequency conversion that is used for receiving is also delayed time to produce the converter 7 and 8 of audio signal, amplifier 9 and 10, described ultrasonic receiver 3 and 4 is separately positioned on the left side of earphone 13, in the auris dextra bag, and amplifier 9 is connected with 12 with audio frequency acoustical generator 11 by lead respectively with 10 outfans, described wave filter 5 and 6, converter 7 and 8 and amplifier 9 and 10 be located in the machine box 14.Supersonic generator 2 and can be installed in the blind man's stick middle and lower part for supersonic generator 2 direct current power source supplying power, gauge tap 1 is arranged on blind man's stick handle place.
After opening gauge tap 1, that supersonic generator 2 sends is very brief, certain hour ultrasonic signal is at interval arranged, when supersonic generator 2 emissions finish, two ultrasonic receivers 3 and 4 electric work, after receiving the echo of ultrasound wave chance objects in front, signal is reached wave filter 5 and 6, filter clutter, keep with the frequency ultrasonic signal, weaken superpower ultrasonic signal (phase mutual interference when avoiding other blind person to use) simultaneously, ultrasonic signal is reached converter 7 and 8, then outage; Two converters 7 and 8 are with ultrasonic signal frequency conversion and time-delay, produce the audio electronics signal and reach two amplifiers 9 and 10 ( amplifier 9 and 10 can be established the volume adjusting knob) respectively, reach audio frequency acoustical generator 11 and 12 then, the blind person can hear the reflection audio signal of melodious long stereo surrounding, thereby in audition, form the solid space of sound sensation, but the solid space profile of object around the perception.
