It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
The embodiment of the utility model provides an explanation ware switching device can realize inserting the earphone with the help of the user and can start the explanation ware, and the user uses very conveniently.
As shown in fig. 1 and 2, the interpreter switch device in the embodiment of the present invention includes an earphone insertion detection device 10 and a power supply unit switchable switch device 20. The earphone insertion detection device 10 is configured to detect whether an earphone is inserted into an earphone jack of the interpreter, and output a detection signal indicating whether the earphone is inserted. The power supply unit switchable switching device 20 is connected between the power supply unit 30 and the interpreter main circuit 40 for switching on a path between the power supply unit 30 and the interpreter main circuit 40 when the earphone insertion detecting device 10 detects that the earphone has been inserted into the earphone jack, so that the power supply unit 30 supplies power to the interpreter main circuit 40.
In practice, the power supply unit 30 may be a battery.
Referring to fig. 1 and 2, a detection signal output terminal of the earphone insertion detection device 10 may be connected to a control signal input terminal of the power supply unit switchable switching device 20. The terminals labeled EN _ POWER in fig. 1 and 2 are the detection signal output terminal of the earphone insertion detection device 10 and the control signal input terminal of the POWER supply unit switchable switching device 20, respectively. In fig. 1 and 2, the two terminals are connected by the same reference numeral "EN _ POWER". When the "EN _ POWER" terminal (i.e., the detection signal output terminal) in fig. 1 outputs the detection signal indicating that the earphone has been inserted, the "EN _ POWER" terminal (i.e., the control signal input terminal) in fig. 2 receives the detection signal and triggers the POWER supply unit switching device 20 to turn on the POWER supply unit 30 and the main interpreter circuit 40.
A detailed implementation of the headphone insertion detection apparatus 10 is described in detail below, and referring to fig. 1, the headphone insertion detection apparatus 10 in the present embodiment is an extension of the headphone jack related circuit. The headphone jack typically has two left and right pins, designated as J1 and J2, respectively. The headphone jack also has a ground terminal J3. In a normal case, when the earphone is inserted into the earphone jack, different areas of the earphone that are isolated from each other are connected to the left pin J1, the right pin J2, and the ground terminal J3. In the embodiment of the present invention, the detection terminal J4 is added, and the detection terminal 4 is designed to connect the grounding terminal J3 and the detection terminal J4 through the earphone after the earphone is inserted into the earphone jack; when the earphone is not plugged into the earphone jack, the grounding terminal J3 and the detection terminal J4 are not conducted. As can be seen from fig. 1 and fig. 2, when the ground terminal J3 and the detection terminal J4 are not turned on, the voltage at the detection terminal J4 is at a high voltage, and when the ground terminal J3 and the detection terminal J4 are turned on, the voltage at the detection terminal J4 is pulled down by the ground terminal J3, and the voltage at the detection terminal J4 is changed to a low voltage. Therefore, whether the earphone is inserted into the earphone jack or not can be detected, the voltage of the detection end J4 is different, and in turn, whether the earphone is inserted into the earphone jack or not can be judged by detecting the voltage change of the detection end J4, so that the voltage signal of the detection end J4 can be considered as a detection signal for indicating whether the earphone is inserted into the earphone jack or not.
The specific implementation of the power supply unit switchable switching device 20 is described in detail below. Referring to fig. 2, the main body of the understanding point unit switchable switching device 20 includes a switchable switching circuit, and a control signal input terminal (i.e., EN _ POWER terminal in fig. 2) of the switchable switching circuit is connected to a detection terminal (i.e., EN _ POWER terminal in fig. 1) of the earphone jack in fig. 1.
The switchable switching circuit includes: and a PMOS component, wherein the source S0 of the PMOS component is connected with the power supply unit 30, the grid G0 of the PMOS component is connected with the detection end J4 of the earphone jack, and the drain D0 of the PMOS component is connected with the main interpreter circuit 40.
Specifically, the gate G0 of the PMOS tube component may be connected to the sense terminal J4 of the headphone jack through a second resistor R31. The PMOS transistor assembly may include a plurality of PMOS transistors connected in parallel. The sources of the PMOS tubes connected in parallel are connected together to form a source S0 of the PMOS tube component. The drains of the PMOS tubes connected in parallel are connected together to form a drain D0 of the PMOS tube assembly, and the gates of the PMOS tubes connected in parallel are connected together to form a gate G0 of the PMOS tube assembly. In the specific example shown in fig. 2, the PMOS tube assembly includes two PMOS tubes connected in parallel, denoted as Q1 and Q2, respectively. The source, gate and drain of the PMOS transistor Q1 are denoted as S1, G1 and D1, respectively. The source, gate and drain of the PMOS transistor Q2 are denoted as S2, G2 and D2, respectively. The gate G0 of the PMOS transistor element may be connected to the source S0 of the PMOS transistor element through a first resistor R30.
Adopt a plurality of PMOS pipes parallel connection to constitute the advantage of PMOS subassembly: the ability of the PMOS components to withstand large currents can be improved.
The operation of the switchable switching circuit is described in detail below.
When the earphone is not inserted into the earphone jack, the source voltage minus the gate voltage of the PMOS transistors Q1 and Q2 is less than the first threshold (e.g., 0.4V), so the source and drain cannot be conducted, and the power supply unit 30 will not supply power to the main circuit 40 of the interpreter, and the interpreter is in a power-off state.
After the earphone is inserted into the earphone jack, the ground terminal J3 is connected to the detection terminal J4, and since the ground terminal J3 is connected to ground, the gate voltages of the PMOS transistors Q1 and Q2 are finally pulled low, so that the voltage difference between the source and the gate is greater than a first threshold (e.g., 0.4V), the source and the drain are connected, and the power supply unit 30 supplies power to the main interpreter circuit 40, and the interpreter is in an on state.
The process just accords with the use habit of the user, when the user inserts the earphone into the earphone jack, the user really wants to start to use the explaining device, and the explaining device can be triggered to start at the same time, so that the user is convenient, and the starting time is more reasonable.
It should be noted that, in the above-mentioned embodiments shown in fig. 1 and fig. 2, the detection signal output terminal of the earphone insertion detection device 10 is directly connected to the control signal input terminal of the power supply unit switchable switch device 20, and the following is implemented by means of the circuit design: by inserting the headset into the headset hole, triggering the power supply unit can switch the switching device 20 to make the path between the power supply unit 30 and the main interpreter circuit 40.
In practice, the detection signal can also be read in and determined by a separate controller, and the controller can send a trigger signal to the power supply unit switchable switching device 20. Specifically, the controller is configured to receive a detection signal output by the earphone insertion detection device 10 and indicating whether the earphone is inserted, determine whether the earphone is inserted into the earphone jack based on the detection signal, and send a control instruction to the power supply unit switchable switch device 20 to trigger the power supply unit switchable switch device 20 to switch on a path between the power supply unit 30 and the interpreter main circuit 40 if the earphone is inserted into the earphone jack.
