Abstract
The utility model relates to a hearing aid for input of multiple sources of sound. The hearing aid comprises a microphone, a signal processor, a frequency divider, a gain amplifier and a receiver that are electrically connected in order. An input end of the signal processor is electrically connected with an external audio input interface. The adoption of the external audio input interface enables the hearing aid to receive input of the multiple sources of sound and allows processing functions of the hearing aid to be expanded. Compared with a recorder and a hearing aid that are separated used, the hearing aid of the utility model is noticeably improved in terms of sound effects.
Description
Technical field
The utility model relates to a kind of hearing aids, relates in particular to a kind of multitone source input hearing aids.
Background technology
Hearing aids is one and helps hearing disabilities person to improve dysacousis, and then instrument, unit and the instrument etc. of raising and his conference communicative competence.The hearing aids of often seeing in the market mainly contains boxlike, hard of hearing formula and customized type.All there is the function singleness defective in existing hearing aids, just simply sound is amplified enhancing, can only simply satisfy the demand of listening barrier patient and other people communication exchange, sound loss is bigger when listening the barrier patient to listen to the music under the situation of using hearing aids, and sound effect is poor.Simultaneously, owing to listen the barrier patient in time to use hearing aids also may not catch speaker's full content fully, for having omission on important meeting or the chat script, common hearing aids is recording and record function not, gives and listens the barrier patient to make troubles.
Publication number is that the utility model patent of CN 201044508 discloses a kind of hearing aids, comprising: be used for finishing conversion, the use pattern between voice signal and the signal of telecommunication and arrange between the pattern switching and to the master controller MCU of setting and the demonstration of parameter; The sound signal amplifier that the sound that is used for gathering amplifies; For the volume adjusting module of respectively volume of left and right acoustic channels being regulated; For the tone adjustment module of respectively tone of left and right acoustic channels being regulated; Be used for showing the LCD display module of hearing aids operating state and parameter; Thin film switch; And the power module that is used for providing power supply; Described voice signal amplification, volume adjusting module, tone adjustment module, LCD display module, thin film switch and power module link to each other with described MCU respectively.The weak point of this hearing aids is function singleness, has only the basic function of hearing aids.
The utility model content
The utility model is in order to overcome the defective of above-mentioned prior art, and a kind of hearing aids that has recording, re-reading and music playback function is provided.
In order to reach the foregoing invention purpose, the technical solution of the utility model is: a kind of multitone source input hearing aids, comprise the microphone, signal processor, frequency divider, gain amplifier and the receiver that are electrically connected in turn, described signal processor input also is electrically connected the external audio input interface.
The signal processor input is electrically connected the external audio input interface, and signal processor can also receive other external device audio signals (such as different mobile phones by the external audio input interface except the audio-frequency information that can receive microphone, computer, TV, MP3, MP4, MP5), easy to use.
Preferably, described microphone output also connects an Audio storage unit, and described Audio storage unit output connects signal processor.When independent recorder and hearing aids work, need the signal of telecommunication be converted to voice signal by recorder, by hearing aids voice signal be converted to the signal of telecommunication, again the signal of telecommunication be amplified output.The signal multiple conversions makes distorted signals, and sound effect is poor.Audio storage unit is converted to the audio-frequency information of storage the signal of telecommunication and passes to signal processor, handles the back by receiver output by signal processor, frequency divider, gain amplifier, compares with using independent recorder and hearing aids sound effect obviously to promote.
Preferably, described external audio input interface is the 3.5mm audio jack.
Preferably, described hearing aids comprises a volume by-pass cock and a mode selection switch.
The beneficial effects of the utility model are:
(1) by the external audio input interface is set, make hearing aids can accept the input of multitone source, make that the processing capacity of hearing aids is expanded;
(2) will the record storage information translation of memory device of Audio storage unit is the signal of telecommunication and passes to signal processor, handle the back by receiver output by signal processor, frequency divider, gain amplifier, compared to using independent recorder and hearing aids sound effect obviously to promote;
(3) be provided with the 3.5mm audio jack, can receive other MP3, mobile phone, the audio-frequency information of apparatus such as computer, and directly be to amplify behind the signal of telecommunication these storage information translation, give and listen barrier patient sound effect more clearly.
Description of drawings
Fig. 1 is theory diagram of the present utility model.
Embodiment
Below in conjunction with concrete the drawings and specific embodiments the utility model is described further:
As shown in Figure 1, a kind of multitone source input hearing aids, comprise the microphone, signal processor, frequency divider, gain amplifier and the receiver that are electrically connected in turn, described microphone output also connects an Audio storage unit, described Audio storage unit output connects signal processor, and described signal processor input also is electrically connected the external audio input interface.Described external audio input interface is the 3.5mm audio jack.Hearing aids is provided with a volume by-pass cock and a mode selection switch, and mode selection switch is divided into 4 grades, is respectively recording, re-reading, hearing aid, MP3, and wherein the MP3 function can select to play the audio file of external equipment audio file or storage inside.
During use, as long as stir the mode selection switch button, can make equipment between hearing aids, recording, re-reading, MP3, carry out function and switch, can make hearing aids be operated in recording mode, re-reading pattern, music playing mode and basic hearing aid pattern.Because integrated recorder function is being attended a lecture on class, and both sides stay occasion such as contact method very practical mutually, can help the user to write down own useful voice messaging effectively easily.The MP3 music playback function has also improved tin barrier patient's entertainment life greatly.Be provided with the 3.5mm audio jack, can receive other MP3, mobile phone, the audio-frequency information of apparatus such as computer, and directly be to amplify behind the signal of telecommunication these storage information translation, give and listen barrier patient sound effect more clearly.
