Summary of the invention
For above-mentioned the deficiencies in the prior art, be necessary to provide a kind of receiver control circuit still under noisy environment with better speech quality.
In addition, there is a need to provide a kind of portable electron device with described receiver control circuit.
A kind of receiver control circuit, comprise the first receiver, the second receiver, dio Output Modules, Noise Acquisition device, diverter switch and control module, described dio Output Modules is electrically connected to described first receiver, for output audio signal; Described dio Output Modules is electrically connected to described second receiver by described diverter switch; Described Noise Acquisition device is for gathering ambient noise; Described control module is electrically connected to described Noise Acquisition device and diverter switch, for receiving the ambient noise that described Noise Acquisition device exports, this ambient noise and a pre-set threshold value are compared, and according to the electric connection that comparative result corresponding control diverter switch is set up or disconnected between described dio Output Modules and described second receiver.
A kind of portable electron device, comprise receiver control circuit and housing, described receiver device control circuit comprises the first receiver, the second receiver, dio Output Modules, Noise Acquisition device, diverter switch and control module, and described first receiver and the second receiver are disposed adjacent on described housing; Described dio Output Modules is electrically connected to described first receiver, for output audio signal; Described dio Output Modules is electrically connected to described second receiver by described diverter switch; Described Noise Acquisition device is for gathering ambient noise; Described control module is electrically connected to described Noise Acquisition device and diverter switch, for receiving the ambient noise that described Noise Acquisition device exports, this ambient noise and a pre-set threshold value are compared, and according to the electric connection that comparative result corresponding control diverter switch is set up or disconnected between described dio Output Modules and described second receiver.
Described receiver control circuit is by arranging the first receiver and the second receiver, and by the control of control module, can make when ambient noise is less than described noise threshold, only by the first receiver output audio signal, and when ambient noise is greater than described noise threshold, the second receiver and the equal output audio signal of the second receiver.Therefore, receiver control circuit not only output volume is larger when ambient noise is larger audio signal can be convenient to answering of user, also when ambient noise is less only by the first receiver output audio signal, can save electric energy.

Following embodiment will further illustrate the present invention in conjunction with above-mentioned accompanying drawing.
Embodiment
Refer to Fig. 1, the receiver control circuit 10 of better embodiment of the present invention is applied to a portable electron device (not shown).Receiver control circuit 10 comprises the first receiver 11, second receiver 12, dio Output Modules 13, Noise Acquisition device 14, diverter switch 15 and control module 16.
First receiver 11 and the second receiver 12 are all arranged in the housing (not shown) of described portable electron device.First receiver 11 and the second receiver 12 are disposed adjacent, and when user uses described portable electron device to listen to sound, the first receiver 11 and the second receiver 12 are all in the coverage of people's ear.
Dio Output Modules 13 is for output audio signal.Dio Output Modules 13 is electrically connected to the first receiver 11, and is electrically connected to the second receiver 12 by diverter switch 15.
Noise Acquisition device 14 for gathering the ambient noise of environment residing for it, and exports control module 16 to.Specific in present embodiment, Noise Acquisition device 14 is for gathering the ambient noise of environment residing for described portable electron device.Here the ambient noise of indication, refers in environment residing for described portable electron device, except other sound except the audio signal that dio Output Modules 13 exports.In the present embodiment, sound collector 51 is microphone.
Diverter switch 15 is electrically connected to the second receiver 12, dio Output Modules 13 and control module 16.Diverter switch 15 is for setting up or disconnecting the electric connection between dio Output Modules 13 and the second receiver 12, thus corresponding control second receiver 12 whether output audio signal.
Control module 16 is electrically connected to Noise Acquisition device 14.The ambient noise that control module 16 exports for receiving Noise Acquisition device 14, compares this ambient noise and a pre-set threshold value, and according to the switching of the corresponding control diverter switch 15 of comparative result, thus the output of control the second receiver 12.Particularly, when the ambient noise that Noise Acquisition device 14 collects is less than this pre-set threshold value, illustrate that now ambient noise is less, control module 16 exports one first control signal and disconnects electric connection between dio Output Modules 13 and the second receiver 12 to control diverter switch 15, now only has the first receiver 11 output audio signal.When the ambient noise that Noise Acquisition device 14 collects is more than or equal to this pre-set threshold value, illustrate that now ambient noise is larger, control module 16 exports one second control signal and sets up electric connection between dio Output Modules 13 and the second receiver 12 to control diverter switch 15, now the first receiver 11 and the second receiver 12 all output audio signals, thus add total volume of the audio signal that described portable electron device exports, be convenient to answering of user.
Described receiver control circuit 10 is by arranging the first receiver 11 and the second receiver 12, and pass through the control of control module 16, can make when ambient noise is less, only by the first receiver 11 output audio signal, and when ambient noise is larger, the first receiver 11 and the second receiver 12 all output audio signals.Therefore, receiver control circuit 10 not only output volume is larger when ambient noise is larger audio signal can be convenient to answering of user, also when ambient noise is less only by the first receiver 11 output audio signal, can save electric energy.
