In the following embodiments, the descriptions of the respective embodiments have respective emphasis, and reference may be made to related descriptions of other embodiments for parts that are not described in detail in a certain embodiment.
The embodiment of the application provides a self-moving device 100, and the self-moving device 100 is a machine device for automatically executing specific work, and can accept human command, run a pre-programmed program, and perform an action according to a principle formulated by an artificial intelligence technology. The mobile robot can be used indoors or outdoors, can be used for industry or families, can be used for replacing security patrol, replacing people to clean the ground, and can also be used for family companions, auxiliary office work and the like. Illustratively, the self-moving device 100 may be: cleaning machines people, industrial robot, intelligent vehicle, unmanned aerial vehicle, family accompany formula mobile device, audio-visual robot, medical mobile device, and patrol formula mobile device etc..
Specifically, in the present embodiment, referring to fig. 1, the self-moving apparatus 100 includes a base 110, a moving device 120, a pose adjusting device 130, a display device 140, and a control device 150.
The base 110 is a structural foundation for bearing other components, and the moving device 120 is disposed at the bottom of the base 110 and is used for driving the base 110 to move, so that the mobile device 100 can move from one position to another position. The moving device 120 may be a crawler-type moving structure, a wheel-type moving structure, or a bionic moving structure, and the present embodiment does not limit the moving device. Here, the moving means 120 is in signal connection with the control means 150, and the control means 150 has a function of controlling the moving means 120 to move the base 110.
The pose adjustment device 130 is disposed on the base 110 and connected to the display device 140, so as to drive the display device 140 to rotate relative to the base 110 to adjust the spatial pose of the display device 140. Here, the posture adjustment device 130 is signal-connected to the control device 150, and the control device 150 can control the posture adjustment device 130 to perform corresponding actions. Here, the posture adjustment device 130 can adjust the spatial posture of the display device 140, so that the display device 140 can better face the user and have a suitable image display posture, so as to improve the use experience of the user.
In some embodiments, referring to fig. 1, the pose adjusting device 130 includes a first driving element 131, the first driving element 131 is connected to the base 110 and has a rotatable first output end, the display device 140 is connected to the first output end, and the first output end can drive the display device 140 to rotate to adjust the spatial pose of the display device 140 when rotating.
Further, as shown in fig. 1, the posture adjusting device 130 may further include a second driving member 132, the second driving member 132 is connected to the base 110 and has a rotatable second output end, the first driving member 131 is connected to the second output end, and the rotation axes of the first output end and the second output end are perpendicular to each other.
For example, referring to fig. 1 and 2, in fig. 2, a direction B is a rotation direction of the first output end, and the first driving member 131 can drive the display device 140 to rotate in the direction B, so that the display device 140 is switched between a portrait screen posture and a landscape screen posture. The display device 140 is in the portrait screen posture, which means that the image currently displayed by the display device 140 is in the portrait screen state, and the display device 140 is in the landscape screen posture, which means that the image currently displayed by the display device 140 is in the portrait screen state. Referring to fig. 1, in fig. 1, the direction a is a rotation direction of the second output end, the second driving element 132 can drive the display device 140 to rotate along the direction a to adjust the pitch state of the display device 140, and during the adjustment of the pitch state, the display device 140 is also switched between the portrait attitude and the landscape attitude. The first driving member 131 and the second driving member 132 may be driving motors or the like.
It is to be understood that the configuration of the posture adjustment device 130 is not limited to the above-described embodiment, and only adjustment of the spatial posture of the display device 140 is possible. For example, in some embodiments, the posture adjustment device 130 may further include a third driving element, and the rotation axes of the output ends of the first driving element 131, the second driving element 132, and the third driving element are perpendicular to each other.
As mentioned above, the display device 140 is connected to the pose adjusting device 130 and can be driven by the pose adjusting device 130 to generate a spatial posture change, that is, can switch between a vertical screen posture and a horizontal screen posture. Meanwhile, the display device 140 also has a plurality of speakers. Here, in order to ensure that the speakers can have a good stereo output effect, the control device 150 controls each of the speakers to perform stereo output according to the spatial posture of the display device 140.
Illustratively, the control device 150 determines the spatial attitude of the display device 140 according to the parameters of the adjustment operation of the pose adjustment device 130 connected by signals, and controls each of the speakers to perform stereo output accordingly, for example, determines the spatial attitude of the display device 140 according to the rotation angle of the pose adjustment device 130 and controls each of the speakers to perform stereo output accordingly. Further illustratively, the control device 150 determines the spatial posture of the display device 140 by detecting data parameters of the display device 140 connected by signals, for example, may detect a window orientation parameter of the display device 140, and control each of the speakers to output stereo sound accordingly. As still another example, referring to fig. 2, the self-moving apparatus 100 may further include a pose sensor 160, the pose sensor 160 is disposed on the display device 140 and is in signal connection with the control device 150, and the pose sensor 160 is configured to detect a spatial pose of the display device 140 and control each of the speakers to output stereo sound accordingly. The pose sensor 160 may be a gravity sensor, a magnetic sensor, or the like.
Here, the display device 140 has opposite first and second sides 145 and 146, and among the speakers, at least one of the speakers is disposed near the first side 145 and at least one of the speakers is disposed near the second side 146. That is, among the plurality of speakers, at least one of the speakers is closer to the first side edge 145 than to the second side edge 146, and at least one of the speakers is closer to the second side edge 146 than to the first side edge 145. For example, the first side 145 and the second side 146 may be left and right sides or upper and lower sides of the display device 140. Also, typically, the speakers are positioned along the first side 145 or the second side 146 so as not to be too far inside and affect the integrity of the image displayed in the middle of the display device 140, while not being too far outside and increasing the volume of the display device 140 too much.
In some embodiments, the speakers are arbitrarily arranged at the first side 145 and the second side 146. It is only necessary that the display device 140 has at least one speaker located on the left side and at least one speaker located on the right side when the display device is in the portrait posture or the landscape posture.
In other embodiments, at least one pair of the speakers is left-right symmetric about a central vertical axis of an image currently displayed by the display device when the display device 140 is in the portrait or landscape orientation. For example, when the display device 140 is in the portrait screen posture, one pair of the speakers is symmetric to the left and right with respect to the central vertical axis of the image currently displayed by the display device 140, and here, due to the symmetric layout of the speakers, the speakers can have a better stereo output effect in the portrait screen posture. For another example, when the display device 140 is in the landscape orientation, one pair of the speakers is symmetric with respect to the vertical central axis of the image currently displayed by the display device 140, and here, due to the symmetric layout of the speakers, the speakers can have a better stereo output effect in the landscape orientation. For another example, the number of the speakers is at least three, at least one pair of the speakers is bilaterally symmetric about a vertical central axis of an image currently displayed by the display device when the display device 140 is in the portrait orientation, and at least one pair of the speakers is bilaterally symmetric about a vertical central axis of an image currently displayed by the display device 140 when the display device is in the landscape orientation. Here, since the display device 140 has the speakers in a symmetrical layout regardless of the portrait posture or the landscape posture, the speakers can be made to have a more excellent stereo output effect.
In some examples, one of the speakers is disposed in the middle of the first side 145 and the other of the speakers is disposed in the middle of the second side 146.
For example, referring to fig. 3, the speakers specifically include a first speaker 141 and a second speaker 142, when the display device 140 is in the landscape posture shown in fig. 3, the first side 145 is a left side of the display device 140, the second side 146 is a right side of the display device 140, the first speaker 141 is disposed in a middle of the first side 145, and the second speaker 142 is disposed in a middle of the second side 146, it is understood that the middle here may refer to a distance range between the middle of the first side 145 and the middle of the second side 146, and does not strictly refer to a central position of the first side 145 and the second side 146.
Here, in the landscape state shown in fig. 3, the first speaker 141 and the second speaker 142 are symmetrical to each other about the vertical central axis α, and here, the vertical central axis of the display device 140 substantially coincides with the vertical central axis of the currently displayed image. The control device 150 controls the first speaker 141 located at the left side of the image currently displayed on the display device 140 to play left channel audio, and controls the second speaker 142 located at the right side of the image currently displayed on the display device 140 to play right channel audio, so as to achieve good stereo playing effect. It is understood that, when the display device 140 is rotated by 180 °, the positions of the first speaker 141 and the second speaker 142 are exchanged, and accordingly, the channels of the played audio are also exchanged.
The vertical screen state can be achieved after the display device 140 is rotated by 90 ° or 270 ° from the state shown in the figure, here, taking the vertical screen state shown in fig. 4 as an example, the first speaker 141 and the second speaker 142 are both located approximately in the area near the middle, and the control device 150 controls the first speaker 141 and the second speaker 142 near the vertical central axis β of the image currently displayed by the display device 140 to play left and right channel mixed audio, so as to achieve a good stereo playing effect.
In some examples, the number of the speakers may be three, and the three speakers are respectively disposed at any three corners of the rectangular display device 140. For example, referring to fig. 5, the first side 145 is a left side of the display device 140, the second side 146 is a right side of the display device 140, the three speakers are respectively a first speaker 141, a second speaker 142 and a third speaker 143, the first speaker 141 is disposed near the first side 145, the second speaker 142 and the third speaker 143 are disposed near the second side 146, and in the landscape state shown in fig. 5, the first speaker 141 and the second speaker 142 are disposed symmetrically with respect to a vertical central axis α of a currently displayed image.
Here, when the display device 140 is in the landscape orientation shown in fig. 5, the control device 150 controls the first speaker 141 located on the left side of the image currently displayed by the display device 140 to play left channel audio, and controls the second speaker 142 and the third speaker 143 located on the right side of the image currently displayed by the display device 140 to play right channel audio, so as to achieve a good stereo playing effect. Preferably, in order to ensure equalization of sound effects, the third speaker 143, which does not have a symmetrically disposed speaker in the current spatial attitude, may also be controlled to be muted. It can be understood that, after the display device 140 rotates 180 °, the positions of the first speaker 141, the second speaker 142 and the third speaker 143 are switched left and right, and accordingly, the channels of the played audio are also switched.
The vertical screen state is achieved when the display device 140 is rotated by 90 ° or 270 ° from the state shown in fig. 5, and here, the second speaker 142 and the third speaker 143 are disposed symmetrically with respect to the vertical central axis β of the currently displayed image. Taking the vertical screen state shown in fig. 6 as an example, the control device 150 controls the second speaker 142 and the first speaker 141 located on the left side of the image currently displayed by the display device 140 to play left channel audio, and controls the third speaker 143 located on the right side of the image currently displayed by the display device 140 to play right channel audio, so as to achieve a good stereo playing effect. Preferably, the first speaker 141 having no symmetrically disposed speaker in the current spatial posture may be controlled to be muted in order to secure the equalization of sound effects.
It is understood that, in other embodiments, three speakers may be disposed at any three corners of the rectangular display device 140, and are not limited to the specific examples shown in fig. 5 and 6.
In some examples, the number of the speakers may be four, and four speakers are respectively disposed at four corners of the rectangular display device 140. Referring to fig. 7, the display device specifically includes a first speaker 141, a second speaker 142, a third speaker 143, and a fourth speaker 144, where the first side 145 is a left side of the display device 140, the second side 146 is a right side of the display device 140, the first speaker 141 and the second speaker 142 are disposed near the first side 145, and the third speaker 143 and the fourth speaker 144 are disposed near the second side 146.
Here, when the display device 140 is in the landscape orientation shown in fig. 7, the first speaker 141 and the fourth speaker 144 are bilaterally symmetric with respect to the central vertical axis α of the currently displayed image, the second speaker 142 and the third speaker 143 are bilaterally symmetric with respect to the central vertical axis α of the currently displayed image, and the control device 150 controls the first speaker 141 and the second speaker 142 located on the left side of the currently displayed image of the display device 140 to play left channel audio and controls the third speaker 143 and the fourth speaker 144 located on the right side of the currently displayed image of the display device 140 to play right channel audio, so as to achieve a good stereo playing effect. It is understood that, after the display device 140 is rotated by 180 °, the positions of the first speaker 141, the second speaker 142, the third speaker 143 and the fourth speaker 144 are changed, and accordingly, the channels of the played audio are also changed. It is understood that, in order to save power consumption, any pair of speakers symmetrically arranged left and right may be controlled to mute.
Taking the vertical screen state shown in fig. 8 as an example, in the current spatial posture, the fourth speaker 144 and the third speaker 143 are bilaterally symmetric with respect to the vertical central axis β of the currently displayed image, the first speaker 141 and the second speaker 142 are bilaterally symmetric with respect to the vertical central axis β of the currently displayed image, and the control device 150 controls the fourth speaker 144 and the first speaker 141 located on the left side of the currently displayed image of the display device 140 to play left channel audio, and controls the second speaker 142 and the third speaker 143 located on the right side of the currently displayed image of the display device 140 to play right channel audio, so as to achieve a good stereo playing effect. It is understood that, in order to save power consumption, any pair of speakers symmetrically arranged left and right may be controlled to mute.
It is understood that in other embodiments, the speakers may not be disposed at the corners of the display device 140. For example, as shown in fig. 9, the first speaker 141, the second speaker 142, and the third speaker 143 are not located at corners of the display device 140. As also shown in fig. 10, the first speaker 141, the second speaker 142, the third speaker 143, and the fourth speaker 144 are not located at corners of the display device 140. Here, the arrangement positions of the speakers need only be such that two of the speakers are bilaterally symmetric about the vertical central axis of the image currently displayed by the display device when the display device 140 is in the portrait orientation, and two of the speakers are bilaterally symmetric about the vertical central axis of the image currently displayed by the display device when the display device 140 is in the landscape orientation.
It can be known that, through the setting of the control device 150 and matching with the layout setting of the speakers, the audio played by the speakers can be matched with the spatial posture of the display device 140. When the pose adjusting device 130 controls the display device 140 to generate a change of the spatial pose, the speakers can switch the playing channels according to the change, so that the audio channels played by the speakers after the spatial pose of the display device 140 is changed can be kept matched with the auditory direction of the user, and the speakers can have a good stereo playing effect.
