Description
Technical Field
The invention relates to medical equipment, in particular to a hearing aid device, and particularly relates to a smart phone hearing aid device.
Background
The hearing aid is a small-sized loudspeaker, which enlarges the originally inaudible sound and then utilizes the residual hearing of the hearing-impaired person to enable the sound to be transmitted to the auditory center of the brain so as to feel the sound. The earphone mainly comprises a microphone, an amplifier, an earphone, a power supply and volume control. Hearing aids are classified into air conduction hearing aids and bone conduction hearing aids according to conduction modes; they are classified by the manner of use into box, glasses, hair clip, behind the ear, in the canal, and deep canal hearing aids.
Since the beginning of the twentieth century electronic hearing aids were being activated, the structure of the hearing aids was not changed much, and they were still composed of a microphone, an amplifier, a receiver, and a power supply. However, the volume of each part of the hearing aid is gradually reduced, the sound quality is gradually improved, and more selective control is provided.
At present, a plurality of hearing aids with the price of tens of thousands of yuan cannot allow the hearing-impaired to hear television sound clearly.
Chinese patent application CN102474697A discloses a hearing aid, a signal processing method, and a program, which easily hear the sound of a television when a hearing aid user wishes to watch the television, and easily hear the sound of another person when they wish to talk with the other person. A hearing aid (100) is provided with a speech detection unit (150) for detecting speech of a speaker other than the hearing aid wearer by using detected sound source direction information, self-speech detection results, and television sound detection results, and a sound source frequency calculation unit (160) for calculating the frequency of each sound source by using the self-speech detection results, the television sound detection results, the other-person speech detection results, and the sound source direction information. A scene discrimination unit (170) discriminates between a 'conversation scene', a 'television viewing scene', and a 'television viewing scene while talking', using the sound source direction information and the frequency of each sound source, and an output sound control unit (180) controls the sound output from the hearing aid (100) according to the discriminated scene. The hearing aid detects and identifies the sound of a wearer, the sound of other people and the sound generated by the television by positioning a sound source, and then performs different processing on the sound of the wearer and the sound of the television, so that the sound of the television can be enhanced as required, and the wearer of the hearing aid can hear the sound of the television more clearly. However, the technical implementation of the scheme is relatively complex and high in cost.
Chinese utility model patent CN203492199U discloses a wireless audiphone for listening to television accompanying sound, including emitter and receiving arrangement, emitter connect by signal preamplifier circuit, speech modulation device and infrared emitter electricity in proper order and form, receiving arrangement connect by infrared receiver, speech receiving circuit, speech modulation circuit, audio amplifier circuit and earphone electricity in proper order and form, infrared emitter and infrared receiver adaptation. The utility model discloses make the personage of hearing disorder can remote, clearly hear television sound (or other sound sources), avoid having too big influence other people with television sound, and overcome and arouse the personage of hearing disorder because the deterioration that long-term superstrong volume stimulation leads to. The wireless hearing aid disclosed in the patent receives information from a television after audio output through a pair of infrared transmitting devices and a receiving device, the infrared transmitting devices are connected with the audio output of the television, and the wireless hearing aid is internally provided with an audio adjusting and modulating circuit and an audio amplifying circuit to complete the simplest hearing aid processing of sound amplification. And controls whether the hearing-impaired person listens to the accompanying sound of the television by opening or closing the infrared transmitting device. The patent only makes a simple amplification (completed by an audio amplification circuit) on the sound of the television, and the effect of listening to the accompanying sound of the television is still poor. This patent controls the sound that whether the user listened to the TV set through letting infrared transmitting device work, and infrared transmitting device places at the TV set side, not near the user, and control is more troublesome, uses inconveniently.
Therefore, there is a need in the art to develop a low-cost, easy-to-use hearing aid that overcomes the above-mentioned drawbacks.
