Description
Technical field
The utility model relates to earphone, especially relates to bluetooth earphone.
Background technology
Along with the popularization of mobile phone, the harmfulness of mobile phone radiation also is familiar with by people gradually, as the company of handset that reduces mobile phone radiation--and the application of bluetooth earphone is also more and more.But operation such as the button on the casing is started shooting, received calls, on-hook, shutdown that present bluetooth earphone can only be to use usually, but other function of tool not, for example can't receive the signal of others, if bluetooth earphone can receive the such function of radio broadcasting, will bring very big facility to the user.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of bluetooth earphone with radio broadcasting receiving function is provided, and this bluetooth earphone can receive radio broadcasting, and can be by the audio output unit output of bluetooth earphone.
To achieve these goals, the utility model proposes a kind of bluetooth earphone with radio broadcasting receiving function, audio frequency input unit that comprise bluetooth module, is electrically connected and audio output unit, also comprise the radio broadcasting signal receiving system that is used to receive radio broadcasting signal with bluetooth module, this radio broadcasting signal receiving system is electrically connected with bluetooth module, and output is coupled to audio output unit.
Preferably, described radio broadcasting signal receiving system is FM (frequency modulation) tuning demodulator.
Preferably, described audio output unit comprises amplifier and the loudspeaker that are linked in sequence, and described audio frequency input unit is a microphone.
Preferably, also comprise audio codec, the output of described radio broadcasting signal receiving system is coupled to audio output unit by audio codec, described bluetooth module is coupled to audio output unit by audio codec, and described audio frequency input unit is coupled to bluetooth module by audio codec.
Preferably, also comprise and be electrically connected, be used at least in talking state with bluetooth module and listen to the button that switches between the radio broadcasting state.
The beneficial effects of the utility model are: owing to set up the radio broadcasting signal receiving system on the basis of existing bluetooth earphone, making bluetooth earphone not only can be linked with bluetooth cellular phone receives calls, and can receive the FM radio broadcasting, increased the function of bluetooth earphone; In addition, by in bluetooth earphone, increasing audio codec, further improved the quality of voice.

Fig. 1 is a theory diagram of the present utility model;
Fig. 2 is the structured flowchart of the utility model specific embodiment one;
Fig. 3 is the structured flowchart of the utility model specific embodiment two.
Embodiment
Specific embodiment one
As shown in Figure 1, bluetooth earphone with radio broadcasting receiving function, comprise bluetooth module, the audio frequency input unit that is electrically connected with this bluetooth module and audio output unit, also comprise the radio broadcasting signal receiving system that is used to receive radio broadcasting signal, this radio broadcasting signal receiving system is electrically connected with bluetooth module, and output is coupled to audio output unit.
Particularly, this bluetooth earphone also comprises button, status indicator LED and the power management module that links to each other with the bluetooth module electricity; Wherein, button is used for switching between the different user modes of bluetooth earphone; Status indicator LED is used for the state of bluetooth earphone is indicated; Power Management Unit is electrically connected with bluetooth module and radio broadcasting signal receiving system and provides power supply for it; As shown in Figure 2, described bluetooth module is that model is the blue tooth stereo chip of BC3MM-EXT, this BC3MM-EXT chip is integrated RF (radio frequency, less radio-frequency), BB (baseband, base band), 1.8v power supply on the sheet, 16 audio frequency CODEC (codec), support stereo, and support FM FM signal receiving function, in addition, this chip also comprises DSP (Digital SignalProcessing, digital signal processor) elimination and SBC (sub-band coding, sub-band coding) the decoding work of responsible speech communication quality such as echo; Described radio broadcasting signal receiving system is FM (frequency modulation) tuning demodulator; This FM (frequency modulation) tuning demodulator links to each other by the I2C bus with the BC3MM-EXT chip; Described audio output unit comprises amplifier and the loudspeaker that are linked in sequence, and this amplifier input terminal links to each other with the output that FM coordinates demodulator with bluetooth module, and described audio frequency input unit is a microphone.
The course of work of foregoing circuit is described below: when phone is thrown mobile phone into, switching key makes this bluetooth earphone be in call mode, and microphone picks up the user's voice signal, and voice signal outputed to bluetooth module, bluetooth module is transmitted into the bluetooth cellular phone of wireless link with it after handling; Simultaneously, when bluetooth cellular phone is received voice signal, pass to the bluetooth module of bluetooth earphone by wireless mode, the bluetooth module is passed to amplifier after handling, and is exported by loudspeaker after amplifying.In addition, by switching key can also realize the hanging up of voice, redial, function such as volume control, each state can show by status indicator LED.
When needs used bluetooth earphone to listen to radio broadcasting, the control button made this bluetooth earphone switch to the FM receiving mode, and the FM tuning demodulator passes through I
2The C bus receives instruction, the reception radio broadcasting signal that the BC3MM-EXT chip is sent; Regulate the instruction that key change BC3MM-EXT chip sends to the FM tuning demodulator, can control the radio broadcasting signal which frequency FM receives.
Specific embodiment two
As shown in Figure 3, the difference with specific embodiment one is: this bluetooth earphone comprises that also model is the audio codec of WM8731.The audio output of FM tuning demodulator and BC3MM-EXT chip is connected with audio codec respectively, audio codec carries out decoding processing to the audio signal of FM tuning demodulator and BC3MM-EXT output, and the audio signal output after the processing is to amplifier, play back through loudspeaker; The output of microphone also links to each other with audio codec, and the microphone picked up audio signals is imported this audio codec, is input in the BC3MM-EXT chip after encoded.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
