Embodiment one, as shown in Figure 1, control switch is an analog switch 1, comprise two single-pole double throw unit, first group of control end I N1 of analog switch 1, IN2 is electrically connected with the control signal output ends PIO pin of the control unit of bluetooth module inside, the first signal input part S1A in first group of switch terminal of two single-pole double throw unit, S2A is electrically connected with first audio signal output end 2 of bluetooth module respectively, secondary signal input S1B, S2B is electrically connected with first audio signal interface 3 of external other tone playing equipments respectively, and first group of stiff end is signal output part D1, D2 is electrically connected with the left and right acoustic channels of stereophone respectively.Analog switch has been mature technology, can use the analog switch of existing multiple model.Control switch can also be other forms of switch, for example passes through the switching circuit of transistor, relay realization etc.
Above-mentioned switch terminal is meant according to control and is used for switching so that make the terminal of the switch of circuit connection that stiff end is meant and can not switches, the terminal of only more fixedly connected switch between different tie points.
Energized and and after bluetooth cellular phone matches, realize that by following control flow switch switches, thereby the realization bluetooth earphone is multi-functional, Fig. 2 has represented control flow of the present utility model:
Please refer to Fig. 1,2, in step 100, whether the continuous detecting bluetooth module of the monitoring unit in the bluetooth module receives the conversation signal of mobile phone, conversation signal comprises that receiving element receives phone signal of calling in and the signal that has phone to transfer to, when detecting bluetooth module and receive the conversation signal of mobile phone, execution in step 101; When bluetooth module does not receive the conversation signal of mobile phone, execution in step 103;
In step 101, the control unit of bluetooth module goes out first control end that controls signal to analog switch 1 by control signal output ends PIO human hair combing waste, can first control signal be set to high level; Control procedure advances to step 102.
In step 102, the control pin of analog switch 1 receives this high level, will connect the path of stereophone and bluetooth module, first audio signal output end 2 of the audio signal output unit of bluetooth module is coupled to the left and right acoustic channels of stereophone, and what this moment, stereophone received is the sound that mobile phone sends; Because whether monitoring unit receives the conversation signal of mobile phone in detecting bluetooth module constantly, so, turn to step 103 immediately in case bluetooth module and mobile phone communication finish;
In step 103, the control unit of bluetooth module goes out second by control signal output ends PIO human hair combing waste and controls signal to analog switch 1, can second control signal be set to low level; Control procedure advances to step 104.
In step 104, the control pin of analog switch 1 receives this low level, will connect the path of stereophone and first audio signal interface 3 that is used to be connected external sound source, first audio signal interface 3 is coupled to the left and right acoustic channels of stereophone, and what this moment, stereophone received is the sound that other tone playing equipments send.
Monitoring unit and control unit can also be the independently unit that is positioned at outside the bluetooth module.
Embodiment two, as shown in Figure 3 on the basis of embodiment one, also is designed to microphone by the changeable connection bluetooth module of control switch and other transfer voice equipment, and it is by second audio signal interface 4 that same microphone is connected other transfer voice equipment.Control switch can be two analog switches 1,6, the path of analog switch 1 control stereophone, and the path of analog switch 6 control microphones, analog switch 6 is for there being the analog switch of a single-pole double throw unit.Second group of control end of analog switch 6 is electrically connected with the control signal output ends PIO pin of bluetooth module, secondary signal output S3B in second group of switch terminal is electrically connected with the audio signal input end 7 of bluetooth module, the first signal output part S3A is electrically connected with second audio signal interface 4 that is used for external other transfer voice equipment, and second group of stiff end is that signal output part D3 is electrically connected with microphone respectively.
Two groups of control ends of control switch receive the same control signal by bluetooth module output, second audio signal output end 5 with microphone when first audio signal output end 2 of bluetooth module is coupled to earphone is electrically connected with the audio signal receiving element of bluetooth module, and can pass through microphone, bluetooth module and mobile communication this moment; Second audio signal output end 5 with microphone when first audio signal interface 3 is coupled to earphone links to each other with second audio signal interface, 4 electricity, and the transmission of sound signals that this moment, microphone picked up is to other transfer voice equipment.
Embodiment three, shown in Fig. 4,5, different with embodiment one or two is that power module has been done improvement, also comprise power module, power module comprises battery, boosting unit, voltage regulation unit, the voltage of battery order is boosted, is exported after the voltage regulation unit voltage stabilizing through boosting unit, for each functional module provides power supply, battery is No. 7 dry cells.Because the required operating voltage of bluetooth module is DC+1.8V, and the voltage of common No. 7 batteries of single-unit is DC+1.5V-+1.2V, the voltage stabilizing again so need boost earlier, boosting unit are DC+2.5V with the voltage transformation of No. 7 battery outputs earlier, again the voltage of output DC+1.8V after the voltage regulation unit voltage stabilizing.Boosting unit comprises integrated circuit U9 and peripheral circuit thereof, and integrated circuit U9 can be for being the IC of RT9266 with model.From the Lx pin of RT9266 is the low-voltage of the 4th pin input DC+1.5V-+1.2V, RT9266 is a small encapsulation, the high efficiency DC/DC IC that boosts, the back of boosting through RT9266 is the high voltage of the 5th pin output DC+2.5V by the VDD pin, and the high voltage of DC+2.5V is through switching tube Q4 input voltage regulation unit.Voltage regulation unit comprises integrated circuit U6 and peripheral circuit thereof, and integrated circuit U6 can be for being the IC of RT9167A18 with model.RT9167A18 is a low-dropout regulator, under the situation that input voltage changes within the specific limits, and output DC+1.8V voltage that can be stable, thus provide operating voltage to bluetooth module.
Because No. 7 volume of battery are bigger, for making the compact conformation of earphone, when structural design, PCB are designed to the U type, the centre is emptied, and makes No. 7 batteries embed PCB central authorities, and as shown in Figure 6, label 8 refers to PCB, and label 9 refers to No. 7 batteries.Like this can maximized saving inner space, make product design thinner, littler.
