Description
Technical field
The utility model relates to medical instruments, and in particular to a kind of auditory prosthesis more particularly to a kind of smart phone hearing aid
Device.
Background technique
Hearing aid is a miniature loudspeaker, and the sound that can't hear originally is expanded, and recycles the remnants for the person that listens to barrier
Hearing enables sound to be sent to brain auditory center, and feels sound.Mainly by microphone, amplifier, earphone, power supply and sound
Five parts of amount regulation composition.Hearing aid is divided into air conduction hearing aid and ossiphone by conduction pattern；It is classified as by usage mode
Boxlike, spectacle, hairpin-type, behind-the-ear, inner ear type, duct-type, deep duct-type hearing aid.
Since earlier 1900s, since electronic hearing aid is activated, there is no too big variations for the structure of hearing aid, still by
Microphone, amplifier, receiver and several parts of power supply are constituted.But the volume of hearing aid parts is gradually reduced, sound quality is increasingly
Improve, there are more selectivity controls.
Currently, the hearing aid of many price members up to ten thousand, tens of thousands of members, it can not allow and listen to barrier person does not hear sound of television.
Chinese utility model patent application CN102474697A discloses hearing aid, signal processing method and program,
Hearing aid user wishes to be easy to hear sound of television when watching TV, is easy to hear other people sound when it is desirable that talking with other people
Sound.Hearing aid (100) has: being detected and is tied using the Sounnd source direction information detected, itself sounding testing result and sound of television
Fruit detects other people sounding detection units (150) of the sounding of the speaker other than hearing aid wearer;And it is sent out using itself
Sound detection result, sound of television testing result, other people sounding testing results and sound source directional information, calculate the frequency of each sound source
Each sound source frequency computing unit (160).Scene judgement unit (170) uses the frequency of Sounnd source direction information and each sound source
Degree differentiates " talk scene ", " audiovisual tv scene " and " audiovisual on one side talk while tv scene ", output sound control unit
(180) sound of hearing aid (100) output is controlled according to the scene determined.The patent application is that hearing aid passes through to sound source
Positioning, detection identify the sound that the sound of wearer, other people sound and television set occur, then to the sound of wearer and
The sound of television set carries out different disposal, so that can according to need the sound of television set is enhanced, so that hearing aid is worn
Wearer can more clearly hear the sound of television set.But the technology of this scheme realizes relative complex, higher cost.
Chinese utility model patent CN203492199U discloses a kind of for listening to the wireless hearing aids of television field frame, packet
Emitter and reception device are included, the emitter is successively by signal pre-amplification circuit, voice modulation device and infrared ray
Transmitter is electrically connected, the reception device successively by infrared receiver, phonetic incepting circuit, voice modulation circuit,
Audio amplifier circuit and earphone are electrically connected, and the RF transmitter is adapted to infrared receiver.The utility model
Enable that dysaudia personage is remote, clearly uppick sound of television (or other sources of sound), avoids opening sound of television
Other people are influenced greatly, and are overcome and caused dysaudia personage due to deteriorating caused by long-term superpower volume stimulation.The patent
The wireless hearing aids pass through a pair of of infrared launcher and reception device receives the information after tv audio output,
Infrared launcher connects the audio output of television set, and wireless hearing aids built-in audio adjusts modulation circuit and audio amplification electricity
Simplest sound amplification hearing aid processing is completed on road.And the person that listens to barrier is controlled by opening or closing infrared launcher whether
Listen to the sound accompaniment of television set.It is (complete by " audio amplifier circuit " that the patent has only done a simple amplification to television sound
At), the effect for listening to television audio is still bad.The patent is by whether allowing infrared launcher to work to control user is
The no sound for listening to television set, and infrared launcher be placed on TV pusher side, not user at one's side, control it is more troublesome, make
With inconvenience.
Therefore, this field needs to research and develop that a kind of cost that can overcome drawbacks described above is low, hearing aid easy to use.
