Abstract
The invention relates to a sound identifying instrument for a deaf person. The sound is detected by a microphone and amplified near frequency points to be sampled and detected respectively so as to obtain strength signals, and the strength signals are used to correspondingly modulate the vibration amplitude or frequency of electromagnetic vibrators and a signal-strength optical displayer. According to the vibration amplitude or frequency and the light intensity, the strength of sound signals near the frequency points is acquired, that is, the frequency and the strength information of the sound signals are obtained by sampling, so that the effect of identifying different sounds and meanings is reached to certain extent. The sound identifying instrument is used with lip read, sign language and a hearing aid used by a partial deaf person to improve the effect mutually, and can be used for training of communication function for the deaf person. The deaf person can use the sound identifying instrument to dance, sense calling and vehicle horn, and the like. A person who can not hear the sound and then can not speak can improve the pronunciation and expression abilities through the instrument and reading lips to compare own pronunciation with the pronunciation of a normal person. The deaf person also can distinguish the directions from continuous sound and discontinuous sound by using the inherent directionality of the microphone. The detection frequency is changed for identifying ultrasonic wave such as animal languages and the like.
Description
Technical field
Present technique relates to a kind of instrument for distinguishing sound of deaf, belongs to life and rehabilitation apparatus.
Background technology
Deaf person's available electron cochlea distinguishes and knows sound, and cochlear implant the nearly 200,000 yuan installation fee of China make its only can be by more than 2,000 ten thousand deaf persons in the only a few people use.It has the wound implant surgery to limit to use and can bring complication also can make audition weak person's remaining congenital hearing disability, its best result of use can only understand eighty per cant and the acoustic nerve blemisher also can't use at all.
Summary of the invention
Detect near the intensity of the several Frequency points of the sound signal of telecommunication, demonstration with several electromagnetic vibrator oscillation intensitys and signal intensity optical indicator represents, allows deaf person's frequency and size information that obtains acoustical signal of sampling in view of the above differentiate the alternative sounds and the meaning thereof to a certain extent.With the inherent directivity of microphone differentiate continuous and interrupted sound from direction.Though but extremely lower than its effect difference cost of cochlear implant, general deaf person affords to use, the acoustic nerve blemisher also can use.Lip-read person and sonifer user cooperate this function to understand sound better, comprising by distinguishing that the key elements such as the rhythm and pace of moving things of knowing sound differentiate relatives' accent etc.Certainly, the training of the result of use of this machine and user has very big relation.Because of not hearing that the not sociable people of sound can improve the ability to express of pronouncing by relatively more own pronunciation of this machine and lip-read and normal person's pronunciation.Know that by being used to distinguish the audition normal person can't distinguish the ultrasound wave such as language of some animals of knowing to this machine of selection that detects frequency.
Description of drawings
Below in conjunction with the embodiment accompanying drawing present technique is further specified.
Fig. 1 is the block diagram that present technique is represented sound characteristic information embodiment with the frequency and the signal intensity optical indicator of vibration.
Fig. 2 is the block diagram that present technique is represented sound characteristic information embodiment with the amplitude and the signal intensity optical indicator of vibration.
The specific embodiment
Acoustical signal is amplified with the microphone detection and with amplifier, reuse is several (has used 5 among the embodiment, the more acoustic informations that obtain of number many more more) frequency selective network and current rectifying and wave filtering circuit detect the intensity of these several frequency signals, (what in fact the suitable selection of the filter circuit time constant of current rectifying and wave filtering circuit can guarantee the signal intensity representative is the envelope of sound waveform, frequency selective network is to be that the center is selected with these several frequencies, and that signal frequency departs from this several frequencies decay more is big more), with these several strength signal corresponding modulating signal intensity optical indicators and the output frequency of VCO circuit or the output size of modulation circuit, frequency is high more or amplitude is big more with acoustical signal is strong more to make their output, and user is sampled in view of the above and learnt that near the size information the several Frequency points of acoustical signal can differentiate the alternative sounds and the meaning thereof to a certain extent.With the inherent directivity of microphone differentiate continuous and interrupted sound from direction.Vibration and lightshow function can be opened by the signal of selecting for use separately as required simultaneously and respectively, and this is selected for use the function of signal also can set up on and off switch by corresponding circuits and realizes.Can be placed on as can not wear the time and only distinguish by the side of and know sound by the demonstration of observation signal intensity optical indicator.This machine can be made wrist formula, earphone-type, hair fastener type or head hoop formula etc., be beneficial to use and each electromagnetic vibrator between have enough distances to be convenient to user to distinguish.Easily being distinguished at 5 electromagnetic vibrators that distribute in one week of wrist of wrist formula, two wrists respectively can also be distinguished with an instrument for distinguishing sound of deaf and know more information.Used microphone, amplifier, frequency selective network (as the RC frequency-selective amplifier), current rectifying and wave filtering circuit, signal intensity optical indicator circuit (as recorder level indication LED array), voltage-controlled oscillator circuit VCO (having multiple), vibration amplitude modulation drive circuit and the electromagnetic vibrator (as the impact printer printhead) be made up of oscillating circuit OSC and modulation circuit and drive circuit (as buffer amplifier circuit) all have ready-made circuit to select for use.The passband of telephone sound quality 300-3400Hz can all transmit the voice meaning.Select among the embodiment 500,800,1200,1800 and 2600Hz as five of frequency selection circuit sampling mid frequencyes, also can select other frequencies as required.
Claims (2)
1. instrument for distinguishing sound of deaf, it is characterized in that: sound is distinguished sampling Detection intensity simultaneously at several Frequency points, with the oscillation intensity of the several electromagnetic vibrator vibrations of these several strength signal corresponding modulating, the sampling frequency information of the comprehensive agreement of user and the oscillation intensity information of acquisition are distinguished to a certain extent and are known the alternative sounds and the meaning thereof.
2. instrument for distinguishing sound of deaf according to claim 1 is characterized in that: connect amplifier back several passages formations of being made up of frequency selective network, current rectifying and wave filtering circuit, signal intensity optical indicator, vibration amplitude modulation drive circuit (or VCO and drive circuit) and electromagnetic vibrator of cascade successively again by microphone; Wherein: microphone and amplifier obtain the signal of telecommunication of required acoustical signal, frequency selective network is determined sampling frequency, the signal intensity optical indicator is used up the signal intensity on each sampling frequency of indication, vibration amplitude modulation drive circuit (or VCO and drive circuit) produces the driving signal of electromagnetic vibrator, whether electromagnetic vibrator allows people's perception oscillation intensity, signal intensity optical indicator and electromagnetic vibrator have the signal deciding of selecting for use separately to select for use.
