Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, embodiment described below the present invention is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Fig. 1 is the process flow diagram of the player method of the multimedia file of one embodiment of the invention, and the method is based on the earphone shown in Fig. 2 and terminal.As shown in Figure 2, electrical connection is realized by contact pin structure 23 between earphone 21 and terminal 22, the type of this contact pin structure 23 includes but not limited to four-part form, contact pin structure 23 comprises the external plug 231 being arranged at earphone 21 side, and being arranged at the circumscription socket 232 of terminal 22 side, external plug 231 comprises the grounding ports, microphone ports, L channel port and the R channel port that connect with predefined procedure.
Terminal 22 mentioned by the embodiment of the present invention is for smart mobile phone, certainly smart mobile phone is not limited to, it can be any terminal with audio playing function, comprise portable communication appts, PDA (Personal Digital Assistant, personal digital assistant or panel computer) etc.
Consult shown in Fig. 1 and Fig. 2, the player method of the present embodiment comprises:
Step S11: the sensor be connected with terminal is set on earphone.
Sensor 20 can release infrared sensor for heat, also can for monitoring earphone 21 whether by the sensing device of other types worn.Sensor 20 is arranged at the side of earphone 21 ear dorsad, and when earphone 21 is worn in ear, need not be formed contact with human body.
Step S12: the using state of sensor Test earphone is also sent to terminal, wherein using state comprises and is worn on ear neutralization and takes out from ear.
Step S13: terminal controls time-out and the broadcasting of multimedia file according to the change of the using state of earphone.Specifically, if the using state of earphone is taken out from ear from being worn in ear to become, then terminal suspends the broadcasting of multimedia file, if the using state of earphone is worn in ear from taking out to become from ear, then and terminal plays multimedia file.
Wherein, multimedia file can be the texts such as audio file or video file, or even the novel of automatic page turning browse mode, picture, PPT.
The fundamental purpose of the embodiment of the present invention is the sensor 20 by being arranged on earphone 21, automatically the using state of in real time or on schedule interval monitoring earphone 21, thus judge that earphone 21 is worn in ear or from ear and take out, and automatically control time-out and the broadcasting of multimedia file according to the change of the using state of earphone 21.Such as in the process using earphone 21 to listen to the music, if user needs the broadcasting suspending music when earphone 21 takes out from ear, then can complete without the need to manually operation control terminal 22, and it is follow-up to continue broadcasting music, only earphone 21 need be worn in ear again, be compared to prior art, the embodiment of the present invention, without the need to user's manual operation terminal 22, can improve the experience of user greatly.
Based on foregoing invention object, release infrared sensor for heat below, introduce time-out and broadcasting that how the embodiment of the present invention carries out multimedia file in detail.
Fig. 3 is the electrical block diagram that in the embodiment of the present invention, heat releases infrared sensor.As shown in Figure 3, heat is released infrared sensor 30 and is comprised optical filter 31, two electrodes contrary pyroelectricity element 32, biasing resistor R, electric capacity C and field effect transistor 33, wherein, two pyroelectricity elements 32 are connected, and be connected in parallel in ground-electrode GND and field effect transistor 33 with biasing resistor 32 and electric capacity C, field effect transistor 33 is connected to terminal 22 by the signal wire 24 shown in Fig. 2, realizes the connection between earphone 21 and terminal 22 with this.
Wherein, the output impedance of two pyroelectricity elements 32 is high, and field effect transistor 33 is for the impedance transformation of whole circuit.Biasing resistor R, for regulating bias current, makes heat release the output current of infrared sensor 30 in an OK range.Due to heat release infrared sensor 30 export be a low frequency weak signal, be very easy to the interference being subject to other electronic components and electromagnetic wave signal, therefore electric capacity C is for forming a wave filter to suppress interference, the type of the electric capacity C of the present embodiment can be (Electromagnetic Interference, electromagnetic interference (EMI)).
The external structure that heat releases infrared sensor 30 is in encapsulation state (as in figure, dotted line represents), and extraneous light can only enter into inside by optical filter 31.Optical filter 31 only allows wavelength to pass through at the infrared ray of 10 microns, i.e. the Infrared wavelength that goes out of human-body emitting, and shields the light of other wavelength.Do not have light enter heat release the inside of infrared sensor 30 time, the electrical effect that two pyroelectricity elements 32 produce is cancelled out each other, and exports electric signal and is almost 0.
When earphone 21 takes out by user from ear, namely earphone 21 using state from be worn in ear become take out from ear time, the arm of user releases infrared sensor 30 near heat, the heat that human body produces is propagated with ultrared form, and infrared ray passes optical filter 31 and focuses on two pyroelectricity elements 32.Because focusing angle is different, two pyroelectricity element 32 temperature variation in the upper morning are different, and the electrical signal intensity of two pyroelectricity element 32 opto-electronic conversion generations is different and polarity is contrary, the superimposed i.e. exportable electric signal by dying down by force of the electric signal that intensity is different.
In like manner, when earphone 21 is worn in ear by user, namely earphone 21 using state from from ear take out become be worn in ear time, heat is released infrared sensor 30 and is produced by the opto-electronic conversion of two pyroelectricity elements 32 and export by the electric signal died down by force.
Based on this, heat is released infrared sensor 30 and is connected to terminal 22 by signal wire 24, with this by by the electric signal died down by force and by the electric signal transmission died down by force to terminal 22.
The electric signal releasing infrared sensor 30 output due to heat is low frequency weak signal, and therefore the terminal 22 of the embodiment of the present invention is provided with signal amplifier further, to carry out power amplification by signal amplifier to electric signal after reception electric signal.
Fig. 4 is the electrical block diagram of signal amplifier in the embodiment of the present invention, and Fig. 5 is the equivalent circuit diagram of signal amplifier shown in Fig. 4.Shown in composition graphs 4 and Fig. 5, the signal amplifier of the present embodiment for adopting the amplifier of triode and direct current negative-feedback circuit, both can ensure the space of the circuit board not increasing terminal 22, can reduce costs again.
Heat is released a part for the electric signal that infrared sensor 30 exports through input port IN+ and IN-, resistance R2 and resistance Re, resistance R1, resistance Rb and resistance Rc input, as a part for input signal.When environment temperature rises, according to calorifics principle, the motion of transistor MOS internal electrical subflow is accelerated, and makes transistor MOS itself produce faint electron stream, causes the electric current flowing through resistance R2 to increase, and export through delivery outlet OUT+ and OUT-after amplifying.
Fig. 6 is the process flow diagram of the player method of the multimedia file of another embodiment of the present invention.On the description basis of above-described embodiment, whether the present embodiment needed the application program judging play multimedia file to open before the time-out controlling multimedia file and broadcasting.
