CN1868428A - Wrist type deaf-person sound-identification device by using tactile sensation and visual sense to substitute for auditory sense - Google Patents

Abstract

A wrist-type sound recognizer for deaf-person features that the auditognosis is replaced by tactile sense and visual sense, that is, the sound signal is electronically converted to vibration signal by piezoelectric ceramics and optical signal by indicating lamp's flash.

Description

Substitute the wrist formula deaf person unscrambler of audition with sense of touch and vision

Technical field the present invention is a kind of micromachine and the electronic installation that designs for the deaf person, it is converted to vibration signal and optical signalling with acoustical signal by electronic technology, substitute the disappearance of audition with sense of touch and vision compensation, near to help to send the ear disorder person perception the sound reaches the perception correlate or evades dangerous purpose.

Background technology is for deaf person's dysacousis, and the remedial measure of taking at present generally is to wear various sonifer, and directly the voice emplifying signal utilizes the remaining hearing ability of patient to come sound recognition.But for the patient that audition completely loses, such as situations such as auditory center damage, audition conduction nerve injury, sonifer is no-good.

The sound perception to some extent that summary of the invention sends for peripheral things for the patient who helps audition and completely lose, the present invention propose to convert acoustical signal to vibration signal and optical signalling, utilize the sense of touch of human body and the audition that vision remedies patient's forfeiture; The vibration signal that converts to and the intensity of optical signalling and fundamental frequency are consistent with acoustical signal, can reflect the basic feature of acoustical signal faithfully, help the hearing disability person to obtain the acoustic information that peripheral things sends.The present invention is integrated in whole functional in the device of a wrist-watch pattern, makes things convenient for the patient to carry and uses; Wherein vibrator is contained in the back side, and direct and patient's wrist contact skin is by the vibration signal after the conversion of skin tactilely-perceptible; Display lamp is contained in the surface, by the optical signal after patient's the vision acquisition conversion.When peripheral things sends the sound, drag sound or the like such as people's voice, running car or the sound of blowing a whistle, article, this moment, vibrator can be with corresponding frequency of sound wave vibration, and display lamp glimmers with correspondent frequency simultaneously.Because vibration is corresponding with optical signalling harmony wave frequency, can also judge the sound of distinguishing that some is special through the patient of initial training, such as my name, simple language etc.

Description of drawings Fig. 1 is a theory diagram of the present invention; Fig. 2 is a kind of circuit theory diagrams of realizing originally debating device, among this figure, audion Q1 forms emitter follower, the audio electrical signal of microphone output is carried out the electric current amplification, by integrated power amplifying circuit U1 audio signal is carried out power amplification afterwards, the light emitting diode of driving pressure electroceramics vibrating reed, regulator potentiometer W1 can regulate output, the amplitude of control vibration and the brightness of light emitting diode; Fig. 3 debates a kind of enforcement figure example of device, and its external form is the same with general wristwatch; Fig. 4, Fig. 5 are the other two all embodiment that debate device, and this example will be debated device and quartz watch or accutron and integrate, and make this debate device and have time display function simultaneously.

The specific embodiment is in the schematic diagram of Fig. 1, pick up generally can be selected small-sized cheaply Electret condenser microphone (being Mai Kefeng) for use, the audio frequency amplifier section can adopt common audio amplifier circuit, this circuit is not strict with the distortion that signal amplifies, because patient's basic feature by sense of touch and visually-perceptible sound.Frequency content outside the filter circuit circuit filtering audio frequency; Drive circuit is mainly considered power problems, makes quiescent current very little; Display lamp selects for use common light emitting diode to get final product.Circuit adopts 6 volts of laminated cell power supplies.

In a kind of realization circuit of Fig. 2, audion Q1 can select 9014 for use, and audio-frequency power amplifier U1 selects LM386 for use, and C1, C2, C3 select the electrochemical capacitor of 3～10 microfarads for use, and C4 selects the electrochemical capacitor of 100 microfarads for use, and the withstand voltage of each electrochemical capacitor is 6 volts.M1 is a mike, and T1 is a piezo-ceramic vibrators, and D1 is a light emitting diode, and potentiometer W1 (4K ohm) is used to adjust the amplitude of amplifier output.The resistance of resistance is respectively among the figure: R1 (3K ohm), R2 (20K ohm), R3 (2K ohm), R4 (100 ohm), R5 (1K ohm).

Claims (2)

1, adopt electroacoustic techniques to substitute audition with sense of touch and vision.

2, be designed to the wrist-watch pattern that wrist is worn.
