Embodiment
The invention provides a kind of mobile communication terminal and driving method thereof that possesses bone-conduction speaker.Below, the present invention is described in detail with reference to accompanying drawing.
Fig. 3 is in the embodiment of the invention, and the bone-conduction speaker driving part is in the front elevation of the mobile communication terminal 100 of the frame center portion of audio tweeter, and Fig. 4 is the frame assumption diagram of mobile communication terminal internal structure among Fig. 3.
As shown in Figure 3, the mobile communication terminal in the embodiment of the invention, the same with prior art, its formation comprises: contact with user's ear, be positioned at the audio tweeter portion 110 on mobile communication terminal 100 tops; Near user's oral area, be positioned at the microphone 140 of mobile communication terminal 100 bottoms; Be positioned at the front of mobile communication terminal 100, show the display part LCD 120 and the key panel 130 that can import user's control command of its driving condition; Be positioned at the bone-conduction speaker portion 150 of audio tweeter portion 110 adjacent locations.
Fig. 4 is the frame assumption diagram of mobile communication terminal 100 internal structures among Fig. 3, and as shown in Figure 4, mobile communication terminal 100 of the present invention includes control part 101; Control part 101 can be controlled sound, the data communication of mobile communication terminal, mobile station modems) and MCU (Micro Controller Unit: microcontroller) constitute its inside be by exporting the converter section control signal, selectively the MSM that audio tweeter portion 110 and bone-conduction speaker portion 150 are driven (Mobile Station Modem:.In addition, at the audio signal output end of control part 101, be provided with and make a choice the converter section 160 of output audio signal to audio tweeter portion 110 and bone-conduction speaker portion 150; Control part 101 and converter section 160 also be connected can output audio signal audio signal wire 102, and to the converter section control signal wire 103 of converter section 160 output switching signals.In addition, converter section 160 also is provided with audio tweeter terminal 161 and bone-conduction speaker terminal 162, can change according to the switching signal of control part 101, to audio tweeter portion 110 and bone-conduction speaker portion 150 output audio signal selectively.In addition, at audio tweeter terminal 161 places of converter section 160, be connected with the loud speaker 111 of audio tweeter portion 110; Bone-conduction speaker terminal 162 places at converter section 160 are connected with bone-conduction speaker portion 150.Wherein, above-mentioned bone-conduction speaker portion 150 refers to, and needn't directly insert in ear, but the vibrations by cheek side bone the snail place of sound conduction to the screw shape that is positioned at the eardrum inboard, thereby allow user's uppick sound.This bone-conduction speaker is very familiar to for the practitioner of the industry, therefore repeats no more.
Secondly, above-mentioned audio tweeter portion 110 comprises: loud speaker 111; Have hollow space, can protect loud speaker 111, be arranged on the external frame 112 in speaker portion 110 fronts; The hollow space of framework 112 externally, pressing button 113 obtains to support by spring 114, in the lower end of pressing button 113, after pressing button 113 is pressed, can export to ground signalling the earthed switch 115 of control part 101.Earthed switch 115 1 end ground connection, the other end and reference power supply VCC are parallel to control part 101.Above-mentioned spring 114 can be by replacing for pressing button 113 provides the various forms of elastic force and the flexible member of material.
Fig. 5 is the flow chart of the mobile communication terminal driving method treatment step of the embodiment of the invention.
With reference to above-mentioned Fig. 3 to Fig. 5, to the mobile communication terminal 100 that possesses bone-conduction speaker, the mobile communication terminal driving method of realizing by selectively working of audio tweeter portion 110 and bone-conduction speaker portion 150 is described as follows.
At first, under general state, the converter section 160 of mobile communication terminal 100 is remaining state such as the step S10 that passes through audio tweeter portion 110 output audio signals among Fig. 3.
Then, whether 101 pairs of pressing buttons of control part 113 produce to push and carry out determining step S20.
According to the judged result of S20 step, if the user audio tweeter portion 110 contact around ear and position such as chin, pressing button 113 will be pushed, earthed switch 115 will be changed ground connection, to control part 101 output low level signals.Control part 101 will be sensed pushing of pressing button 113 according to this low level signal, and by switching signal line 103 output changeover control signals, converter section 160 will be converted into bone-conduction speaker portion 150 then.Receive the converter section 160 of changeover control signal,, the audio signal conversion is input to bone-conduction speaker portion 150 by audio signal wire 102.Like this, need not the output of voice signal, the user just can pass through bone-conduction speaker uppick audio signal, and other people also can't hear voice signal, thereby can protect the step S30 of individual privacy effectively.
Then, whether terminal has been removed to push to pressing button 113 and has been carried out determining step S40.
Judged result according to the S40 step, when pressing button 113 is not removed when not pushing, terminal will keep the transition status of current bone-conduction speaker portion 150, by bone-conduction speaker portion 150 output audios, return the S40 step then, whether the releasing of pressing button is pushed carry out monitoring step S50.
Different therewith is, judged result according to the S40 step, if the user removes audio tweeter portion 110 around ear and near the chin, under the effect of spring 114, pressing button 113 just will return original position, push promptly and be disengaged, earthed switch also disconnects ground connection, by reference power supply VCC again to control part 101 input high level signals.After control part 101 receives high level signal, to converter section 160 output changeover control signals, be converted into audio tweeter portion 110 again; Converter section 160 is carried out conversion then, to audio tweeter portion 110 output audio signals.
And, in above-mentioned treatment step, judged result according to the S20 step, if be in talking state, and at terminal plays multimedia file output audio signal, the user does not press pressing button 113, when audio tweeter portion 110 is placed on ear, converter section 160 will remain the state S60 to audio tweeter portion 110 output audio signals.
Above-mentioned Fig. 3 to Fig. 5 is the explanation to the embodiment of the invention, different therewith is, for the bone-conduction speaker drive division among the present invention, also can with its functional configuration on the particular key of mobile communication terminal push panel, pushing of button be driven according to the user.
In addition, the invention described above goes for all mobile communication terminals of cover type, flip-type, slide cover type etc.
