Embodiment
Make specific introduce to the present invention below in conjunction with the drawings and specific embodiments.
Shown in reference picture 1, a kind of method for closing display device of the present invention, the display device includes sound and plays list
Member, specifically include following steps：
S10, the echo that the sound playing unit plays sound is obtained, judges whether echo meets the first preparatory condition.
First preparatory condition is：The difference of the acoustical phase of the phase of the echo and the sound playing unit output be less than or
Equal to the poor threshold value of preset phase, and the waveform of the echo is similar to sound waveform that the sound playing unit exports
Similarity threshold of the degree more than or equal to predetermined waveform.Need exist for explanation, the poor threshold value and predetermined waveform of preset phase
Similarity threshold can be set according to the actual requirements, be not any limitation as herein.On how to obtain output sound and return
The phase of sound, the technological means of waveform are prior art, and not in this to go forth.
S20, if meeting first preparatory condition, calculate the voltage magnitude of the echo.The voltage magnitude can be with
The volume of echo is interpreted as, voltage magnitude is also big if the giving great volume of echo, the voltage magnitude if the volume of echo is small
It is small.In addition, the technological means of the voltage magnitude on how to calculate echo is prior art, not in this to go forth.
S30, judges whether the voltage magnitude of the echo meets the second preparatory condition.The voltage for judging the echo
Whether amplitude meets that the method for the second preparatory condition is：The voltage magnitude of the echo and predeterminated voltage amplitude are contrasted,
If voltage magnitude is in the predeterminated voltage amplitude range, meet the second preparatory condition.In order to obtain the default electricity
Amplitude range is pressed, needs first to follow the steps below before S10：
When display device all is clear ahead, the echo that the sound playing unit plays sound is repeatedly obtained；
The voltage magnitude of the multiple echo is calculated, the scope of obtained multiple voltage magnitudes is predeterminated voltage amplitude model
Enclose.
Foundation above step, the control voltage magnitude scope of display device local environment can be obtained, i.e., in no user
Voltage magnitude scope when front uses display device.When user is when using display device, the volume of echo can increase, and make
The predeterminated voltage amplitude range can also be exceeded by obtaining the voltage magnitude of echo.
S40, if meeting second preparatory condition, close display device.
In one embodiment of the invention, closing the method for display device will not only make the voltage magnitude of echo meet the
Two preparatory conditions, it is also necessary to which the voltage magnitude persistently meets second preparatory condition within a certain period of time, could close aobvious
Showing device.Like this, for the previous period, display device does not turn off user's display device away from keyboard yet.
Shown in reference picture 2, the invention also provides a kind of display device, including sound playing unit 101, the display dress
