Abstract
The invention relates to a deaf sound discerning apparatus. The apparatus adopts a microphone to test sound and amplifies the sound in the vicinity of a plurality of frequency points for respective sampling and testing and a plurality of intensity signals are acquired. The intensity signals are used for modulating the vibration amplitude or the frequency of a plurality of electromagnetic vibrators and the signal intensity of an optical display correspondingly. The value of signals in the vicinity of the frequency points are obtained based on the amplitude or the frequency and the light intensity, namely, the frequency and the value data of a sound signal are obtained by sampling so as to achieve the effects of discerning different sounds and the meanings of the sounds to a certain degree. The deaf sound discerning apparatus, lip-reading, dummy statement and a hearing aid used by a person of partial deafness can improve effects mutually. The deaf sound discerning apparatus can be used for communication function training for the deaf. The deaf can dance, and perceive calling and vehicle horn, and the like, by the apparatus. People who can not speak because of deafness can compare own pronunciations with the pronunciations of normal people by the apparatus and lip-reading, thus improving pronunciation and expression abilities. The inherent directivity of the microphone can be used for discerning the directions of the continuous and the discontinuous sounds. The sound discerning apparatus also can be used for discerning ultrasonic waves, such as animal language, and the like, by changing the testing frequency.
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 is distinguished and is known sound, and the nearly 200,000 yuan installation fee of cochlear implant only can be used it by only a few people among China more than 2,000 ten thousand deaf persons, cochlear implant is implanted has invasive procedures to limit the use crowd and brings complication and can make audition weak person's remaining congenital hearing disability, the acoustic nerve blemisher also can't use cochlear implant at all, and what the cochlear implant result of use was best can only understand eighty per cant.
Summary of the invention
Detect near the intensity of the several Frequency points of the sound signal of telecommunication, demonstration with several electromagnetic vibrator vibration amplitudes or frequency and signal intensity optical indicator is represented, allow the deaf person sample in view of the above and obtain the frequency and the size information of acoustical signal, to 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 low compared with 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 detects with microphone and amplifies with amplifier, can add the compression of signal magnitude scope during amplification and manually reach automatic electric-level control, 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 signal intensity of these several frequencies, (what in fact the 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, user is sampled in view of the above and is learnt near the size information that the several Frequency points of acoustical signal are, reaches the effect of differentiating the alternative sounds and the meaning thereof.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-watch, earphone, hair fastener or head hoop formula etc., be beneficial to use and each electromagnetic vibrator between have enough distances to be convenient to user to distinguish them.Being distinguished easily at 5 electromagnetic vibrators that distribute in one week of wrist of watch style, 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 (3)
1. this patent relates to a kind of instrument for distinguishing sound of deaf, it is characterized in that: sound is distinguished sample detecting intensity simultaneously near several Frequency points, with the amplitude or the frequency of the several electromagnetic vibrators of these several strength signal corresponding modulating vibration, user is sampled the frequency that obtains sound and amplitude information in view of the above and is distinguished to a certain extent and know the alternative sounds and the meaning thereof.
