Description

The hearing aid that the deaf-mute uses, training and entertainment systems

Affiliated technical field

The utility model relates to a kind of medical electronics auxiliary system, especially a kind of hearing aid, training and entertainment systems of using towards each age level deaf-mute.

Background technology

Usually, the medical electronics auxiliary system of using towards the deaf-mute is mainly hearing aids.Traditional hearing aid can be reduced to a sound intensifier, mainly comprises: microphone, preamplifier, post amplifier, earphone.For the voice signal that amplifies, most deaf-mute may feel to some extent, but some especially those are from the little children that become deaf, they often do not understand the content of being listened.In this respect, periodic training is necessary.In addition, to the deaf-mute, on the one hand, they wish and can exchange as the normal person, and on the other hand, they also wish to enjoy each electronic product as the normal person, for example: the entertainment effect that TV, smart mobile phone, panel computer bring.Traditional hearing aids is suitable for Language Communication, the entertainment applications of the aspect that is unsuitable for for example listening to the music.Reason is that its earphone frequency band is narrow, in addition, also can't overcome the interference that background noise brings.

Summary of the invention

In order to overcome the shortcoming of existing hearing aids, the utility model provides a kind of deaf-mute to use, and integrates the Novel medical electronic assistant of hearing aid, training, amusement function.

The technical scheme that the utility model adopts is: a kind of hearing aid, training and entertainment systems, it is characterized in that, and comprising: transmitter unit, receiving element, earphone; Described transmitter unit, it is characterized in that, comprise: microphone and amplifier, data storage, MP3/MP4/MP5 player, digital radio audio emitter, these functional modules integrate, and have that volume is little, integrated level is high, tonequality is good, the effect of strong interference immunity; Described receiving element is characterized in that, comprising: microphone and amplifier, signal processor, power amplifier, amplitude-frequency regulator, digital radio audio receiver; Described transmitter unit and receiving element is characterized in that: connect, adopt 2 microphone denoisings by digital radio mode; Described earphone, it is characterized in that, comprise: the left and right acoustic channels earphone, earphone inside comprises at least two oscillator unit, an oscillator element excitation (for example: 20 10000 hertz of He Zi –) vibration and voice signal produces medium and low frequency, this signal passes to deaf-mute's auditory nerve by skin or bone, another oscillator element excitation produces medium-high frequency, and (for example: 10,000 20000 hertz of He Zi –) vibration and voice signal, this signal passes to deaf-mute's auditory nerve by air or ear-drum.

Embodiment

As shown in Figure 1, the hearing aid that a kind of deaf-mute uses, training and entertainment systems 1 comprise transmitter unit 11, receiving element 12, earphone 13.Transmitter unit 11 comprises a microphone and amplifier 11a, data storage 11b, MP3/MP4/MP5 player 11c, digital radio audio emitter 11d, these functional modules integrate, and have that volume is little, integrated level is high, tonequality is good, the effect of strong interference immunity.Data storage 11b can be built-in storage chip, can be also USB flash disk, SD card of outside plug type etc.Training courseware or those contents that is used for amusement are stored in data storage with MP3, MP4 or MP5 form, follow play command, by the digital radio audio emitter, audio frequency (stereo) signal wireless are propagated in air and go.The built-in microphone of transmitter unit 11 and amplifier 11a, therefore, except audio signal, the speech signals that microphone is surveyed and the background noise of surveying, also in the lump by the digital radio audio emitter, radio transmission is in air.Except the content in direct collection microphone input signal, played data memory, transmitter unit also can be directly and other multimedia devices, such as: the wired connections such as TV, computer, mobile phone, VCD/DVD, collected audio signal wireless transmission is gone out.Receiving element 12 comprises a microphone and amplifier 12a, signal processor 12b, power amplifier 12c, amplitude-frequency regulator 12d, digital radio audio receiver 12e.Receiving element receives and demodulates by the digital radio audio receiver the three class signals altogether that transmitter unit sends, and the first kind is the microphone collection signal, and Equations of The Second Kind is the content play signal, and the 3rd class is the multimedia device play signal.The present invention includes 2 microphones, be built in respectively in transmitter unit and receiving element.Signal processor (for example: difference processing), effectively eliminated background noise, improved the amplitude of normal signal carries out relevant treatment to the signal of 2 microphone collections.The signal that the ANTENN AUDIO receiver receives further amplifies by power amplifier, is accompanied by amplitude-frequency regulator, and the user can facilitate the amplitude in regulation output signal averaging amplitude and the selected band limits of fine setting.Therefore, technical solution provided by the utility model extensively be suitable for slightly, moderate and severe deafness patient and those deaf-mutes to indivedual frequency range sensitivities.The system that the utility model discloses provides three kinds of work to touch formula: (1) speaking mode, (2) training pattern, (3) multimedia audio-visual pattern.Can conveniently switch between each quasi-mode, not interfere with each other, realize the effect of hearing aid, training and amusement multifunctional all.Earphone 13 comprises L channel earphone 13a and R channel earphone 13b.

Fig. 2 provides Headphone structure schematic diagram described in the utility model.Earphone inside comprises at least two oscillator unit, an oscillator unit 21, another oscillator unit 22.The suitable inertia mass in oscillator unit 21 is connected on housing by spring.Under electromagnetic force, excitation produces medium and low frequency, and (for example: 20 10000 hertz of He Zi –) vibration and voice signal, this signal passes to deaf-mute's auditory nerve by skin or bone.Another oscillator unit 22 suitable flexible vibrating diaphragms, under electromagnetic force, excitation produces medium-high frequency, and (for example: 10,000 20000 hertz of He Zi –) vibration and voice signal, this signal passes to deaf-mute's auditory nerve by air or ear-drum.The earphone that the utility model discloses, its frequency response is wide, and the whole audible frequency range of nearly cover are not only applicable to talk with communication, the application scenario of the amusement aspect such as yet be suitable for listening to the music.The hearing aid that the utility model discloses, training and entertainment systems are suitable for all kinds of crowds with dysaudia and hearing loss.
