Embodiment repeats no more.
The exemplary embodiment of the disclosure one provides a kind of method for management of shutting down, as shown in figure 1, the processing stream of this method
Journey can include the steps：
Step S110, by power sense circuit, the close event of power supply is preset in multiple power supplys of detection device, its
In, default power supply is the power supply before the power supply of governor circuit and audio discharge circuit is come in power-off sequential.
Wherein, audio discharge circuit is the audio amplification for governor circuit is exported, and play out.Audio amplifier
Circuit includes earpiece audio discharge circuit, loudspeaker audio discharge circuit.
When the power supply of governor circuit is closed, a sharp impulse wave can be produced at once, in Fig. 2, by circle circle
Residence is sharp impulse wave.In embodiments of the present invention, main purpose is to not play this impulse wave.
In force, in the mainboard of a television set, including multiple power supplys.First, mainboard can take 220V civil power, take
After obtaining civil power, civil power is carried out by Transformer Rectifier by power circuit, civil power is transformed into other circuits in mainboard to make
Power supply.Usually, civil power can be transformed into the direct current that voltage is 12V, then the direct current that voltage is 12V is continued to turn
It is changed to other common voltage direct currents such as 5V, 3.3V.In closing television machine, these direct currents are not all directly to close, and
It is to be closed successively according to sequential according to certain logic.Therefore, in order to which in shutdown, power sense circuit energy is first it is detected that be
, it is necessary to set power sense circuit detection to come governor circuit and sound in power-off sequential during no generation power off event
The close event of power supply before the power supply of frequency discharge circuit, rather than a random power supply.
Alternatively, power sense circuit includes first resistor, second resistance, 3rd resistor and triode：First resistor

The second pin of pipe is connected with the first pin of first resistor.
In force, as shown in figure 3, power sense circuit includes R1, R2, R3, V1 and VD1.In the circuit, detect
Power supply be voltage be 5V direct current.In figure 3, R1 is first resistor, and R2 is second resistance, and R3 is 3rd resistor, and V1 is
Triode, VD1 are voltage-stabiliser tube.In the case where 5V power supplies are not turned off state, R1 and R2 points must be except the supply voltage u1 in addition to voltage-stabiliser tube.R1
Get u1 u11 and u12 according to the ratio of resistance with R2.Then the voltage of V1 base stage pin is identical with the voltage on R2, is
u12.Then, it is believed that the voltage of V1 base stage pin is high level, and V1 is turned on, the electricity for the governor circuit being connected with V1 emitter-base bandgap grading
The level that source detection pin detects is high level.When 5V power supplies are closed, the voltage gradual rolloff of V1 base stage pin
To 0V, it is believed that the voltage of V1 base stage pin is low level, and V1 is not turned on, the power supply for the governor circuit being connected with V1 emitter-base bandgap grading
Detection pin is in vacant state.Logic as being set in governor circuit：When detecting that power detecting pin is in
Ground state, it is believed that there occurs television set shutdown event, then carry out step S120.
Alternatively, method provided in an embodiment of the present invention also includes：The pressure drop of voltage-stabiliser tube is determined by following formula 1：
Wherein, x is the pressure drop of voltage-stabiliser tube, and U is the voltage of default power supply, and R1 is the resistance of first resistor, and R2 is the second electricity
The resistance of resistance, △ u are the conducting voltage of triode.
It should be noted that the pressure drop of suitable voltage-stabiliser tube can be obtained, by choosing appropriate voltage-stabiliser tube to adjust electricity
The detection sensitivity of power sense circuit.When the pressure drop of voltage-stabiliser tube is closer to the voltage of default power supply, the spirit of power sense circuit
Sensitivity is higher.Specifically, the pressure drop of voltage-stabiliser tube first has to the voltage for being less than default power supply.Secondly, when default power supply passes through voltage stabilizing
After pipe, voltage declines, if voltage drops too low, can cause the brownout of the base stage pin of triode, it is impossible to turn on,
Therefore power sense circuit cisco unity malfunction.So by the pressure drop of voltage-stabiliser tube according to the voltage and triode of default power supply
Voltage needed for conducting, determine the pressure drop of voltage-stabiliser tube.It is specific to determine that formula be as shown in formula 1.
As seen from Figure 3, the structure of power sense circuit is simple, and component is fewer, therefore, power sense circuit pair
The reaction of the close event of default power supply will be correspondingly rapid.And then before sharp impulse wave plays back, to strive for
The effective time reacted with processing.
Step S120, when detecting the close event of default power supply, governor circuit is cut off to the sound of audio discharge circuit
Frequency exports, so that audio discharge circuit stops playing audio.
In force, as shown in figure 4, the master chip of governor circuit is SoC, the power supply of governor circuit is u3, and R4 is current limliting
Resistance.Power sense circuit is A mute, and power sense circuit includes R1, R2, R3, V1 and VD1, and u1, u2 are power supplies.Sound
Frequency discharge circuit is Headphone.In Headphone, HP P_HP1_L are the left audio input pin of first passage,
HP P_HP1_R are the right audio channel input pin of first passage.By taking Headphone as an example, when A mute detect default electricity
During the close event in source, SoC is cut off to the audio output of the Headphone pins of HP P_HP1_L and HP P_HP1_R two.
When between SoC and Headphone, during in the absence of audio, impulse wave would not be also produced.
Alternatively, default power supply is the power supply of sequential at first in power-off sequential.
For example, there are four kinds of power supplys, respectively 12V, 8V, 5V, 3.3V on mainboard, in power-off sequential, by most arriving first
The power supply that last order is closed successively is：3.3V、8V、5V、12V.It is thereby possible to select whether detection 3.3V power supplys are closed
Close, before sharp impulse wave plays back, to strive for the effective time reacted with processing.
The method provided by the present embodiment, when detecting the close event of default power supply, cuts off governor circuit to sound
The audio output of frequency discharge circuit, so that audio discharge circuit stops playing audio.Default power supply is in power-off sequential
The power supply before the power supply of governor circuit and audio discharge circuit is come, in this manner it is possible in governor circuit and audio amplifier electricity
Before the power supply on road is terminated, first the situation that television set shuts down is checked to come, raced against time for further processing.So,
Immediately before governor circuit closing, governor circuit is cut off to the audio output of audio discharge circuit, when the output of no audio
When, impulse wave would not be produced, having been cut off from root may caused by impulse wave.
