Further, it is determined according to the range information of the user and projection device and the outside environmental sounds being presently in
Go out to project volume, the user is closer with projection device, and the projection volume of projection device is smaller；User gets over projection device
Far；The projection volume of its projection device is bigger so that meets it and is in demand of the user of different location to projection volume；It should
When the outside environmental sounds being presently in are larger, the projection volume of the projection device determined enables to big also because larger
It can be heard by user in outside environmental sounds；Avoid user and projection device apart from each other and project volume it is smaller caused by
Can not hear clearly and user and projection device at a distance of projected compared with close volume it is larger caused by too loudly the problem of.It uses at this time
The correspondence at the distance between family and projection device, outside environmental sounds and projection volume can pass through the multiple of staff
Experiment obtains its best volume relationship table.The best volume relationship table includes the environment nowadays sound of light sensor detection
Amount, range information and projection volume, at this time projection device get the range information and outside environmental sounds with user

Shadow plays so that the best volume viewing of user can be achieved.
Further, projection angle can determine that according to the angle information of the user and projection device so that its projection is set
It is standby to carry out offset projection towards towards one end of user when being projected, avoid user and the projection device at a distance of orientation compared with
The problem of causing user that can not see project content clearly when big.
Further, projection device is after determining projective parameter, and control is instructed with the projective parameter response control, specifically
, for example, when user is located at the front of projection device, and according to its projection device farther out when says broadcasting target film, at this time
Projection is gone out that a projection size is larger, projection brightness is brighter, volume is larger and projection angle is placed in the middle for projection by this
Target film.
Sound control method provided in an embodiment of the present invention, the voice messaging sent out by acquisition user is to parse voice
Command information in information and voiceprint, wherein command information pass through acquisition for realizing the control to projection device
Voiceprint can determine that the location information of user, determine corresponding projective parameter according to the location information of user at this time, such as
Projection size, projection brightness, projection volume etc. are determined at a distance from projection device according to user, according to user and projection device
Orientation determine projection angle etc. so that the projection device can meet user be presently in position projection play needs, and
The projective parameter of existing projection device remains unchanged always, when user needs to adjust the parameter informations such as projection volume, needs to lead to
The adjustment of projective parameter could be realized by crossing remote keying, can be automatically determined out at a distance from projection device according to user in the present invention
Required projective parameter, and control projection device and projected with the projective parameter, it is inconvenient for use to solve existing projection device
Prompt problem.
Embodiment two：
Fig. 2, the flow chart of the sound control method provided in the second embodiment of the present invention are please referred to, this method is applied to
Projection device, this approach includes the following steps：
Step S201 controls the projection device and switches to monitoring when receiving the default voice messaging that user sends out
Pattern；
Wherein, it should be pointed out that realize that the energy consumption to the projection device controls, and avoid real-time response user's language
The chaotic problem that message is brought when ceasing, projection device are equipped with multiple-working mode, and operating mode includes mainly standby mould
Formula, listening mode and response modes are not sent out user wherein in stand-by mode, projection device is in low power consumpting state
The voice messaging gone out is responded.In the listen mode, the voice messaging that projection device real-time reception user sends out, projects at this time
Equipment is changed into normal power consumption state by low power consumpting state.Under response modes, projection device carries out the voice messaging of reception
Response.
Projection device in stand-by mode, can obtain the voice messaging that user sends out, but it does not switch to monitoring at this time
When under pattern, which can not be responded, at this time when projection device gets default voice messaging, this time control
Make the projection device and switch to listening mode, it is possible to understand that the default voice messaging pre-set for user, can be existing
Have common " hello " etc..
Step S202, the voice messaging that real-time reception user sends out under the listening mode, the voice messaging include
Command information and voiceprint；
Wherein, when getting the default voice messaging that user sends out, control switches to listening mode, is monitoring mould at this time
Under formula, voice messaging that real-time reception user sends out.
Wherein, it should be pointed out that in listening mode, projection device real-time monitoring users in preset time are sent out
Voice messaging, when it does not receive the voice messaging that user sends out in preset time, control switch to standby mode,
Continue standby processing at this time, to save power consumption.
Step S203 parses to obtain the control instruction that user sends out according to described instruction information；
Wherein, when receiving the voice messaging that user sends out in preset time, then the voice messaging is parsed
To obtain the control instruction that user sends out.
Step S204 determines that user is relatively described according to the voiceprint and the outside environmental sounds being presently in
The location information of projection device.
Step S205, determines the projective parameter of the projection device according to the positional information, and controls the projection and set
It is standby that the control instruction is responded with the projective parameter；
Wherein, it should be pointed out that may further determine that the identity characteristic information of user, wherein identity characteristic according to voiceprint
Information includes age information and gender information, for example, according to wave volume, sound frequency in the user's voiceprint got
Etc. information can determine age information and the gender information of user.
Determine that the projective parameter of projection device further includes at this time：The projection ginseng of projection device is determined according to identity characteristic information
Number.For example, when determining that user is older user according to the voiceprint for sending out voice messaging, projection ginseng can determine
Projection size in number is large-size, and projection volume is larger volume etc., at this time so that its older user is in eye
See project content in the case of eyeball presbyopic clearly, user does not hear broadcast information in the case of hard of hearing so that can be improved user's
Experience sense, the wherein correspondence of the identity characteristic information of user and projective parameter can be obtained by many experiments of staff
To its optimal parameter relation table.When projection device gets the identity characteristic information with user at this time, by searching for the best ginseng
Number relation table can determine that corresponding projective parameter, and the projective parameter determined according to location information is combined and determines to need to project
Parameter, for example, when the closer position of its older user distance projection device needs to watch target film, although at this time
User is closer away from projection device distance, but older due to user, and projection size is larger, sees throwing clearly to meet user
The demand of shadow content.
Further, the voice messaging sent out such as user is when recommending film, according to the age information of user and property
Other information can determine that matched recommendation film so that promote user experience.
Step S206, when not receiving the voice messaging that user sends out in the first preset time, described in control
Projection device stops responding the control instruction；
Wherein, for projection device when being responded to control instruction, it is in projection state at this time, default first at this time
Judge whether to receive the voice messaging that user sends out in time, when the voice for receiving user in the first preset time and sending out
When information, the voice messaging is responded.When not receiving the voice messaging that user sends out in the first preset time, the throwing at this time
Shadow equipment stops response control instruction, that is, stops projection broadcasting, for example, when user's control projection device plays target film,
Its projection device can not judge that user whether also in the viewing stage, controls the mesh at this time after playing longer period of time
Mark the broadcasting of film.
Step S207 controls the projection device and sends out prompt message, to prompt the user whether to continue to control the projection
Equipment responds the control instruction；
Wherein, projection device sends out prompt message, to prompt the user whether to carry out after the response for stopping control instruction
Response control instructs, it is possible to understand that, the prompt message which sends out can be one prompt of pop-up in project content
Frame, to prompt the user whether to continue the broadcasting of target film；Or suggestion voice is sent out by loud speaker, with prompt the user whether after
The broadcasting of continuous target film.
Step S208, when the confirmation voice for receiving the confirmation prompt message that user sends out in the second preset time
When information, controls the projection device and proceed to respond to the control instruction；
Wherein, when user sends out confirmation voice messaging in the second preset time, and control instruction is proceeded to respond to confirm,
Projection device control proceeds to respond to the control instruction, for example, after projection device sends out prompt message, user, which sends out, to continue to play
Voice messaging when, the projection device continues the broadcasting of the target film at this time, until the target film finishes.
Step S209, when not receiving the confirmation voice messaging that user sends out in second preset time,
The projection device is controlled to stop responding the control instruction.
Wherein, when not sending out confirmation voice messaging in the second preset time as user, then projection device control stops
Response control instructs, for example, when not closed to the projection device when user is busy outgoing in the midway for watching film,
Projection device is constantly in response modes, leads to the power consumption for increasing projection device, when projection device is playing target film extremely
When the first preset time, prompt message is sent out, whether continues to play with prompt, not received when in the second preset time
When the confirmation voice messaging that user sends out, stop the broadcasting of the target film at this time, and switch to standby mode, so that can save
About energy consumption.
Further, when projection device, which receives the confirmation that user sends out, stops the confirmation message of response control instruction,
It stops response control instruction.For example, when user receives prompt message, user sends out the voice messaging for stopping playing, this
When the projection device stop the broadcasting of the target film, and be switched to listening mode by response modes, sent out with to receive user
Voice messaging.When not receiving the voice messaging that user sends out in preset time, then standby mode is switched to, so that section
About energy consumption.
The sound control method provided through the above way is set by controlling projection when default voice messaging has not been obtained
It is standby to be in standby mode, listening mode is switched to when getting default voice messaging, is being listened to voice messaging and is being rung
At once response modes are switched to so that can be achieved to control the energy consumption of the projection device, while avoiding real-time response user speech
