Embodiment
For making those of ordinary skill in the art clearly understand the object, technical solutions and advantages of the present invention, below in conjunction with drawings and Examples, the present invention is further elaborated.
Shown in figure 1, in some embodiments of the invention, Mobile phone talkback companion 10 includes the radio-frequency antenna 14 and being connected to this intercommunication module 12 for Mobile phone talkback companion 10 and the interface module 13, that mobile phone 20 carries out being connected that intercommunication module 12, that a master controller 11, is connected to this master controller 11 is connected to this master controller 11 and provides the electric supply installation 15 of working power for Mobile phone talkback companion 10.
Command signal and voice signal for receiving the command signal and voice signal that come from mobile phone 20, and are sent to master controller 11 and intercommunication module 12 by this interface module 11 respectively.The voice signal of described interface module 11 also for described intercommunication module 13 being exported sends to mobile phone.Wherein, according to the actual requirements an APP software can be installed on mobile phone, described command signal, voice signal be converted to the analog signal form needed for interface module 11 or digital signal form.The interface module 11 of Fig. 1 is earphone microphone interface module 111a, by can realize the connection of mobile phone 20 and this Mobile phone talkback companion 10 once the connecting line of band double end headset plug when user uses.Mobile phone earphone microphone interface conventional at present mainly meets two kinds of standards, namely OMTP standard (is commonly referred to national standard, plug connection is: L channel-R channel-microphone-ground wire) and CTIA standard (be commonly referred to international standard, contact pin connection is: L channel-R channel-ground wire-microphone).Therefore, MIC signal transmitting and receiving can be realized by this earphone microphone interface module 111a, the transmitting-receiving of earphone left and right binaural signal, keypress function three kinds of basic functions.In the present embodiment, this earphone microphone interface module 111a is for receiving the command signal and voice signal that send from mobile phone 20, and described command signal is left and right binaural audio signal, and described voice signal is MIC signal, and the two is analog signal.
This command signal, for receiving and resolving the command signal that interface module 11 transmits, then sends to intercommunication module 13 to arrange the running parameter of this intercommunication module 13 and to control the receipts/hair-like state of described intercommunication module 13 by described master controller 12.Described master controller 12 also works for interface module 11 according to the working state control of described intercommunication module 13.Described master controller 12 can be the MCU of multiple conventional model, as STM32F030F4.
Described intercommunication module 13 is for receiving and resolving the command signal that master controller 12 sends, and produce a control data, the voice signal that receiving interface module 11 sends, and voice signal is processed (analog-to-digital conversion, encryption etc.), then convert the voice signal after this control data and process to radiofrequency signal and be sent to radio-frequency antenna 15; The radiofrequency signal of described intercommunication module also for being sent by described radio-frequency antenna 15 converts voice signal and control data to, resolves this control data and judges whether this voice signal to be sent to described interface module 11.
General intercommunication module 13, for wireless voice intercommunication and transfer of data, comprises rf chip, microcontroller and radio-frequency (RF) power amplification etc.Because antijamming capability is strong, speech quality is good, frequency efficiency advantages of higher, general use digitlization intercommunication module at present.But the voice I/O interface of digitlization intercommunication module is generally analog signal interface, therefore, the simulated audio signal of input can be converted to digital audio and video signals by this digitlization intercommunication module, exports after digital audio and video signals being converted to simulated audio signal.Intercommunication module 13 of the present invention is preferably the intercommunication module 13 (as models such as HKT-81BK) of the above-mentioned type.Intercommunication module 13 receives the command signal that master controller 12 sends, and according to set running parameter work, and is in reception or transmission state.The running parameter of the intercommunication module 13 arranged is needed mainly to comprise: bandwidth, tranmitting frequency value, receive frequency value, infrasonic frequency etc.In use, intercommunication module 13 is generally defaulted as accepting state to Mobile phone talkback companion 10 of the present invention, and in an Intranet, tranmitting frequency, receive frequency are arranged on corresponding frequency according to agreement by all users.
When intercommunication module 13 is in transmission state, described intercommunication module 13 is resolved this command signal and is produced a control data, this control data can be the data increasing infrasonic frequency in a digital audio signal or produce measures such as digital audio and video signals are encrypted, can certainly be other control data.This intercommunication module 13 also converts the voice signal of reception to digital audio and video signals, then converts this control data and digital audio and video signals to radiofrequency signal and is sent to radio-frequency antenna 15.When intercommunication module 13 is in accepting state, described intercommunication module 13 converts digital audio and video signals and control data to for the radiofrequency signal sent by described radio-frequency antenna 15, resolves this control data and then determines whether to need this digital audio and video signals is converted to simulated audio signal and sends to described interface module 11.Such as, if control data when launching has infrasonic frequency information, receive user and judge that the infrasonic frequency information received is consistent with oneself, then can accept this digital audio and video signals; If receive user do not arrange same subsonics value, then directly abandon this digital audio and video signals.If control data when launching does not require infrasonic frequency information, then some receptions are with accepting this digital audio and video signals per family.
Described electric supply installation 14 comprises the power management module 142a, lithium battery 141a, the usb interface module 143a that are connected with described master controller 12 respectively, and described usb interface module 143a is connected with lithium battery 141a by power management module 142a.According to actual user demand, described usb interface module 143a can coordinate to be embodied as this lithium battery 141a as power input port with power management module 142a and charge; Described usb interface module 143a also can to coordinate with power management module 142a as output port of power source and is embodied as external equipment and charges.In addition, electric supply installation 14 also comprises the display module 144a be connected with master controller 12, master controller 12 carries out electricity monitoring to this lithium battery 141a and (namely generally measures cell voltage by master controller 12, then according to the magnitude of voltage estimation electricity measured), and this information about power is shown through display module 144a, improve Consumer's Experience greatly.When lithium battery 141a electricity is lower, the connection of usb interface module 143a and external equipment can also be disconnected by master controller 12, forbid outside equipment charge.
