Abstract
The invention relates to a voice self-test visual chart, belongs to manufacture technology field of medical appliance. The visual chart consists of display device, character window and voice apparatus, wherein the character window is provided on visual chart display, the voice apparatus includes earphone, mike and voice emitter. Earphone and mike are linked with voice emitter with wire, visual chart display is connected with voice emitter by 'Bluetooth' wireless system. When the chart is used, power will be turned on, and the detecting people wear earphone and mike. When testing character is light, correct direction selection should be made using 'up-down-right-left' voice in desired time limit. When selection is correct, voice of 'correct judgment, go on testing' will be sent out from the earphone, and higher level test will be carried out continuously. When selection is wrong, voice of 'false judgment, go on trying' will be send out from the earphone, the test will stop in this level and continues, no longer upgrades to higher level. The voice self-test visual chart of this invention has following advantages: professional design, simple structure, and convenient for use, etc.
Description
Technical field
The present invention relates to a kind of self-testing eye chart with speech instruction, belong to manufacture technology field of medical appliance.
Background technology
When common logarithmic visual acuity chart is tested the tester, need tester and another people to assist to carry out, tester self can't detect the vision of oneself with logarithmic visual acuity chart, uses inconvenient.And because logarithmic visual acuity chart is a leaflet, and the direction of each symbol is fixed, can not randomly changing, so the somebody carried on the back symbol opening direction of each row in order to detect by vision, also can get by under false pretences, and lost the seriousness that detects.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, but provide a kind of reasonable in design, simple in structure, use reliable stochastic transformation character and self-testing eye chart with speech instruction that can single use.
The objective of the invention is to be achieved through the following technical solutions: a kind of self-testing eye chart with speech instruction, form by visual acuity chart display, character window and voice device, wherein, the visual acuity chart display is provided with the character window, voice device includes earphone, Mike and voice transmission device, earphone is connected with the voice transmission device by lead with Mike, is connected by " bluetooth " wireless system between visual acuity chart display and the voice transmission device.
Described visual acuity chart display is made up of housing and display window, is arranged with " E " font or " C " font of dwindling by logarithmic relationship in the display window and detects character, and character is provided by liquid crystal display.
When the present invention used, with energized, conducting was to tester's earphone Mike, when the test character lights, in the time that requires, make correct direction and select, when selection is correct, send the voice of " correct judgment, continuation detect " in the earphone with the voice of " up and down ", continuation detects to rank more, when selecting mistake, transmit the voice of " misjudge please keep punching " in the earphone, and rest on this rank and detect, no longer upgrade to higher level.Advantages such as it is reasonable in design, simple in structure, easy to use that the present invention has.
Description of drawings
Fig. 1 is a visual acuity chart display sketch map of the present invention;
Fig. 2 is a voice transmission device sketch map of the present invention.
Wherein: 1, visual acuity chart display, 2, the character window, 3, earphone, 4, Mike, 5, the voice transmission device.
The specific embodiment
Embodiment: structure as shown in drawings, form by visual acuity chart display 1, character window 2, earphone 3, Mike 4, voice transmission device, wherein, visual acuity chart display 1 is provided with character window 2, voice device is earphone 3, Mike 4 and voice transmission device 5, and earphone 3 is connected with voice transmission device 5 by lead with Mike 4.Be connected by " bluetooth " wireless system between visual acuity chart display 1 and the voice transmission device 5.Visual acuity chart display 1 is made up of housing and display window, be arranged with " E " font or " C " font of dwindling by logarithmic relationship in the display window and detect character, character is provided by liquid crystal display and energy stochastic transformation opening direction, the detection order is descending carries out successively, the character that is detecting shows as high brightness and shows, the character of each grade every 5 seconds randomness conversion first powers to, correct continuously selection three times after, enter the detection of higher level automatically.Voice signal up and down is transformed to four kinds of corresponding signals of telecommunication by speech recognition device, be emitted to the receiving circuit of visual acuity chart display 1, and when using by receiving circuit correcting errors of judging that direction selects, with energized, be conducting to tester's earphone 3 and Mike 2, when the test character lights, in the time that requires, make correct direction and select, when selection is correct, send the voice of " correct judgment; continue to detect " in the earphone 3 with the voice of " up and down ", continuation detects to rank more, when selecting mistake, transmit the voice of " misjudge please keep punching " in the earphone 3, and rest on this rank and detect, no longer upgrade to higher level.Advantages such as it is reasonable in design, simple in structure, easy to use that the present invention has.
Claims (2)
1, a kind of self-testing eye chart with speech instruction, it is characterized in that, form by visual acuity chart display, character window and voice device, wherein, the visual acuity chart display is provided with the character window, voice device includes earphone, Mike and voice transmission device, and earphone is connected with the voice transmission device by lead with Mike, is connected by " bluetooth " wireless system between visual acuity chart display and the voice transmission device.
