Fig. 6 shows a kind of illustrative circuit structure of vibrating motor control circuit according to the embodiment of the present disclosure.Such as Shown in Fig. 6, the connecting element of J3, J4, J5, J6 namely for connecting vibration motor.Wherein each connecting element includes two Endpoint 1,2, is connected respectively to one end of the stator winding of vibrating motor.Node M 3Check and M4Check shown in Fig. 5 A points It is not the test point for the motor status of two vibrating motors.In some embodiments, it can will test and a little be set as vibrating No. 1 point in the connecting element of motor, as shown in Figure 6.

The circuit structure according to shown in Fig. 6, when vibrating motor work, PWM input terminal input low level, at this time in Q5 At common emitter amplifying circuit, emitter junction no-bias, collector junction reverse biased；Cut-off region；It disconnects.At Q4: U (BC) > 0, current collection Tie forward bias；Saturation region；U (CE)=0, emitter and collector is such as switch connection, resistance very little；Pressure drop all on R11, Current collection extremely low level.At Q2: the base stage of Q2 is connected with the collector of Q4, so its base stage is exactly low level；Cut-off region； It disconnects.At Q6: the base stage of Q6 is connected with the collector of Q4, so his base stage is exactly low level, U (CE) < U (BE), current collection Pole forward bias；Saturation region；Emitter also forward bias；U (CE)=0, emitter and collector is such as switch connection, conducting. At Q3: R12 cannot obtain voltage, and NMOS tube grid is low level, be not turned on.Therefore, the electricity of test point M3Check at this time Pressure is exactly VCC voltage, is in high level.That is, detection sub-circuit 122 is collected by node M 3Check, M4Check The motor status of high level detects signal.

When vibrating motor does not work, PWM input terminal input high level, at this time at Q5 common emitter amplifying circuit, input Export paraphase (i.e. in digital circuit, input height then export it is low, input it is low, export height, electricity of the collector relative to emitter Position is about 0.2v, is low level, a section lead is equivalent to after conducting, is grounded, and pressure drop is just all on R13, locating for collector Position is exactly low level, does not drive next stage triode ON)；U (CE) < U (BE), collector forward bias；Saturation region；Hair Emitter-base bandgap grading also forward bias；U (CE)=0, emitter and collector is such as switch connection, conducting.At Q4, the base stage of Q4 is with Q5's Collector is connected, so its base stage is exactly low level；Cut-off region；It disconnects.It is total at collector amplifying circuit in Q2, input and output Same phase；U (B)>U (E), U (BE)>0, emitter junction forward bias, U (B)<U (C), U (BC)<0, collector junction reverse biased；Conducting. At Q6, U (B) > U (E), U (BE) > 0, emitter inverse bias, U (B) > U (C), U (BC) > 0, collector junction reverse biased；At Q6 In cut-off region；It disconnects.At Q3, NMOS tube grid obtains Q2 and exports high level, conducting.Therefore, test point M3Check at this time It is equivalent to and is directly grounded, be in low level.That is, detection sub-circuit 122 is acquired by node M 3Check, M4Check Signal is detected to low level motor status.

As described above, detection sub-circuit 122 is by the level value at acquisition testing point M3Check and M4Check as electricity Machine state detection signal, and to control 124 output motor status signal of sub-circuit.When vibrating motor starts to work normally, inspection Level value at measuring point occurs height and changes, and the motor status signal for detecting the output of sub-circuit 122 is caused to change therewith. If control sub-circuit 124 detects motor status signal intensity, issue what indication motor worked normally to instruction sub-circuit Control signal.Corresponding lumination of light emitting diode is controlled by serial ports for example, a low level can be exported.When vibrating motor or When person's connecting line exception, the level value at test point is high level, by controlling triode ON after resistance, thus to control Circuit output corresponds to the motor status signal (for example, low level) of abnormality.When control sub-circuit 124 detects motor shape When state signal corresponds to the motor status signal of abnormality, then the control letter of indication motor failure is issued to instruction sub-circuit Number.For example, a high level can be issued, so that corresponding light emitting diode will not shine in instruction sub-circuit, failure is prompted.

As described above, detection sub-circuit is examined by the level value at collection point M1Check and M2Check as motor status Survey signal, and to control 124 output motor status signal of sub-circuit.Control sub-circuit 124 judges received motor status signal Whether the motor status signal that when push-rod electric machine work normally should export is met.If controlling the received motor of sub-circuit 124 Status signal indicates that push-rod electric machine works normally, then issues the control signal that indication motor works normally to instruction sub-circuit.

Corresponding lumination of light emitting diode is controlled by serial ports for example, a low level can be exported.If control son electricity The received motor status signal designation push-rod electric machine in road 124 does not work normally, then issues indication motor event to instruction sub-circuit The control signal of barrier.For example, a high level can be issued, so that corresponding light emitting diode will not be sent out in instruction sub-circuit Light prompts failure.In some embodiments, control sub-circuit 124 may determine that the level value of received motor status signal is The no control mainboard for meeting beddo exports the level of the relay to corresponding motor.If the two is different, control luminous two Pole tube light-emitting, instruction work normally.If the two is identical, controls light emitting diode and do not shine, indicates failure.
