Embodiment
With reference to Fig. 2, Fig. 2 shows audio frequency of the present invention and wakes operation principle up.In the inside of mobile terminal external equipment, set up a Rouser.This Rouser is connected with the audio interface of mobile terminal (wakener), the audio signal E that mobile terminal receive sends, and after receiving specific audio signal, this Rouser can produce a wake-up signal D and drive external equipment, and external equipment is waken up to operating state from resting state.Here, wake-up signal D can be a level saltus step or pulse.
Particularly, first need to insert wake-up device to work on power by audio interface, can detect audio interface according to the MIC pin bias voltage of audio frequency of mobile terminal interface and insert, that is, judge whether audio frequency MIC line is connected with Rouser.In the situation that not inserting audio interface, self does not power on Rouser.Only, when inserting audio interface, Rouser just works on power.After Rouser work, use audio interface and communication of mobile terminal, and the instruction of sending according to mobile terminal, determine whether other functional modules of Rouser to wake up.When receiving that the audio frequency of mobile terminal wakes instruction up, Rouser is converted into single wake-up signal by it, and in triggering external equipment, other each functional modules wakes up.After externally equipment is waken up, Rouser just passes peripheral hardware information by audio signal is transmitted to external equipment, to avoid the loss of audio control signal.
With reference to Fig. 3, Fig. 3 shows the structured flowchart of Rouser of the present invention.This Rouser mainly consists of power on-off control circuit, Audio processing circuit and processor circuit.Wherein, power on-off control circuit comprises MIC insertion detection circuit and electronic switch, whether this MIC insertion detection circuit inspection has the audio frequency MIC line of mobile terminal to be connected with Rouser, in the situation that audio frequency MIC line being detected and being connected with Rouser, controlling this electronic switch opens, the power supply of external equipment is powered on to Audio processing circuit and processor circuit, thereby the work of having controlled this two parts circuit whether.
The audio signal E that Audio processing circuit sends for mobile terminal receive, and audio signal E is nursed one's health into the signal of being convenient to processor circuit decoding.And the signal that Audio processing circuit also can send processor circuit is modulated into and is easy to be moved the audio signal that terminal receives.
Processor circuit can be decoded to the audio signal after conditioning, in the situation that audio signal is wake command, wakes other functional modules of external equipment up; In the situation that audio signal is sleep command, make other functional modules of external equipment enter park mode.
Fig. 4 shows the concrete structure of the power on-off control circuit of one embodiment of the invention.As shown in Figure 4, triode Q4 and Q5 with and peripheral resistance R 16, R18, R19, R20 form MIC insertion detection circuit; Triode Q3 with and peripheral resistance R 23, R24, R15, R17 form electronic switch.
MIC insertion detection circuit can be according to the MIC pin bias voltage of audio frequency of mobile terminal interface, and whether the audio frequency MIC line that detects mobile terminal is connected with Rouser, usings this as the foundation whether powering on to Rouser.
Because the base stage of triode Q3 is connected with external equipment power supply VBAT_CON by peripheral resistance R 23, R24, in the situation that externally equipment is not connected with mobile terminal, Q3 base stage is high level, and Q3 is in cut-off state, and Rouser is not worked.
And after external equipment is connected with mobile terminal, between the PHONEJACK_PIN3 of audio frequency of mobile terminal interface and PHONEJACK_PIN4, there is voltage difference, this voltage difference is the MIC pin bias voltage that mobile terminal provides.When having voltage difference to exist, no matter in PHONEJACK_PIN3 and PHONEJACK_PIN4, which point voltage is high, all can cause a conducting in triode Q4 or Q5, thereby cause triode Q3 conducting, external equipment power supply VBAT_CON is to processor circuit and Audio processing circuit (VCC_A network) power supply of Rouser.
The reason that two symmetrical transistor circuit Q4 and Q5 are set is, audio interface is divided into international standard, two kinds of standards of domestic standard, both differences are that the position of MIC and GND is different, one of MIC position is the 3rd pin (GND is the 4th pin) of headset plug, and one is the 4th pin (GND is the 3rd pin).In Fig. 4, transistor circuit Q4 and Q5 detect respectively the audio interface of international standard and domestic standard, their collector electrode links together by resistance R 15, R17 respectively, with or logic control opening and closure of electronic switch Q3, in triode Q4, Q5 during any one conducting, it is low level that capital makes the base stage of triode Q3, thus conducting Q3.
It may be noted that, circuit shown in Fig. 4 is a kind of concrete exemplifying embodiment of power on-off control circuit, wherein, and alternatively, MIC insertion detection circuit can only include in above-mentioned transistor circuit Q4, Q5, a kind of in corresponding detection international standard, domestic standard audio interface; Above-mentioned switch triode Q3 also can adopt metal-oxide-semiconductor field effect transistor.
Processor circuit can be selected general single-chip microcomputer, for example, selects STM8 processor, as shown in Figure 5.While earphone insertion being detected in Rouser, VCC_A network power supply, like this, processor circuit brings into operation.Wake command is sent by mobile terminal, is adjusted to audio signal E and sends to external equipment.In Fig. 5, after processor circuit powers on, by its L_TTL pin, the audio signal of earphone mouth L channel is decoded, determine whether wake command, if so, by its WAKEUP pin, wake other functional modules of external equipment up.Processor circuit also can, according to the sleep command in audio signal, make other functional modules of external equipment enter park mode by its SLEEP pin.
With reference to Fig. 6, the Audio processing circuit diagram that Fig. 6 is one embodiment of the invention.Wherein, audio signal E that mobile terminal sends first carries out DC-isolation through capacitor C 3, then, by an input of analog computing amplifier U2A, is received, and it is amplified to processing, then be input in processor circuit and decode through output.The reference signal REF that another input of analog computing amplifier U2A receives, produces via the node between resistance R 2, R3.Preferably, R2 and R3 resistance are equal, and they are connected in series between VCC_A and ground, and to processor power supply voltage, VCC_A carries out dividing potential drop.Like this, reference signal REF is 1/2 processor power supply voltage, and therefore, the audio signal of inputting can be moved near 1/2 magnitude of voltage on amplitude territory, facilitates processor circuit decoding.
Obviously, the present invention described here can have many variations, and this variation can not be thought and departs from the spirit and scope of the present invention.Therefore, all changes that it will be apparent to those skilled in the art, within being all included in the covering scope of appended claims.
