Abstract
The utility model relates to a wireless earphone system for input of multiple sources of sound. The wireless earphone system comprises a host and an earphone. The earphone comprises a wireless reception device, an audio analysis processor, an intelligent gain amplifier and a receiver that are electrically connected in order. The host comprises a microphone, a signal processor and a wireless emission device that are electrically connected in order. The wireless emission device matches the wireless reception device. An output end of the microphone is electrically connected with a memory, an output end of the memory is electrically connected with the signal processor, and 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 multiple sources of sound to be received by a hearing aid and enables processing functions of the hearing aid to be expanded. Functions of a conventional hearing aid are combined with functions of a recorder to make the processing functions of the hearing aid expand, so that the wireless earphone system of the utility model has functions of recording and repeating besides the functions of the hearing aid and is more convenient to use.
Description
Technical field
The utility model relates to the wireless headphone system of a kind of multitone source input.
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.
At present, wireless headset substitutes wired earphone more and more.The line of wireless headset in the middle of being replaced by electric wave, is that the audio frequency outlet from computer is connected to transmitting terminal, sent to by electric wave in the earphone of receiving terminal by transmitting terminal again, and receiving terminal is the equal of a broadcast receiver exactly.Wireless headset has and knownly has three types.One is bluetooth earphone, and two is Infrared earphone, and three is 2.4G.
The utility model content
The utility model provides the wireless headphone system of a kind of multitone source input in order to overcome the defective of above-mentioned prior art.
In order to reach the foregoing invention purpose, the technical solution of the utility model is: the wireless headphone system of a kind of multitone source input, comprise main frame and ear-micro phone, described ear-micro phone comprises the radio receiver that is electrically connected in turn, audio frequency analysis processor, intelligence gain amplifier and receiver, described main frame comprises the microphone that is electrically connected in turn, signal processor, wireless launcher, described wireless launcher and radio receiver are adaptive, described microphone output also is electrically connected a memory, the memory output is electrically connected signal processor, and described signal processor input also is electrically connected with 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 by the external audio input interface except can receiving the audio-frequency information that carries Audio storage unit.
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.In this patent, Audio storage unit is converted to the recorded message of storage the signal of telecommunication and passes to signal processor, sent to the radio receiver of ear-micro phone after the signal processor processes by wireless launcher, obviously promote through being exported by receiver after the audio frequency analysis processor of ear-micro phone, the processing of intelligent gain amplifier, comparing with using independent recorder and hearing aids sound effect again.
Preferably, described external audio input interface is the 3.5mm audio jack.
Preferably, described ear-micro phone is provided with a volume by-pass cock, a mode selection switch and a wireless coupling switch.
Preferably, described main frame is provided with load button and display screen.
Preferably, described radio transmitting device and radio receiver are wireless transmission, receiving systems such as mutual bluetooth of mating or 2.4G.
Wireless headphone system of the present utility model is particularly suitable for as hearing aids.
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) existing hearing aids and recorder function are integrated, made that the processing capacity of hearing aids is expanded, possessed recording, record function except function of hearing aid;
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;
4) adopt wireless transmission between main frame and the ear-micro phone, make the constraint of breaking away from line between main frame and the ear-micro phone, use convenient.
