In order to have a better understanding of the above-mentioned and other aspects of the present disclosure, the following embodiments are given and described in detail with the accompanying drawings as follows:

Please refer to FIG. 1 , which shows a schematic diagram of a smart speaker operating system 1000 according to an embodiment. The smart speaker operation system 1000 includes a mobile device 100 and a smart speaker 200 . The mobile device 100 is, for example, a smart phone, a tablet computer or a notebook computer. In this embodiment, the mobile device 100 can install an application program (App), and the application program allows the user to set the dot pattern PT. The mobile device 100 further determines, according to the size of the dot pattern PT, that the dot pattern PT is too large and requires a mobile display, so the moving direction MD is set. After the mobile device 100 transmits the dot pattern PT and the moving direction MD to the smart speaker 200, the smart speaker 200 can display the dot pattern PT according to the moving direction MD. In this way, the interactive experience between the smart speaker 200 and the user can be enriched.

Please refer to FIG. 2 , which shows a block diagram of a smart speaker operating system 1000 according to an embodiment. The smart speaker operation system 1000 includes a mobile device 100 and a smart speaker 200 . The mobile device 100 includes a processor 110 , a transmission module 120 , a memory 130 and a user interface 140 . The smart speaker 200 includes a controller 210 , a receiving module 220 , a memory 230 and an LED matrix 240 . The processor 110 is, for example, a chip, a circuit, or a circuit board. The transmission module 120 is, for example, a wifi transmission module, a Bluetooth transmission module, or an NFC transmission module. The memory 130 is, for example, an eMMC embedded memory or a flash memory. The user interface 140 is, for example, a touch display panel or an active pen. The controller 210 is, for example, a chip, a circuit, or a circuit board. The receiving module 220 is, for example, a wifi receiving module and a bluetooth receiving module. The memory 230 is, for example, a flash memory or an eMMC embedded memory. The LED matrix 240 is, for example, a square matrix or a rectangular matrix composed of several LEDs. The operation of each of the above elements is described in detail below with a flow chart.

Please refer to FIG. 3 , which is a flowchart of a method for dynamically adjusting the dot matrix pattern of the smart speaker 200 according to an embodiment. In step S301 , the dot pattern PT is set through the user interface 140 of the mobile device 100 . Please refer to FIG. 4, which illustrates an example of step S301. For example, the user may draw the dot pattern PT on the user interface 140 with the finger FG. Each square touched by the finger FG is an LED that is expected to be displayed. Users can intuitively select and draw each square. Alternatively, the user can click the select pattern button K1 to select the pre-stored dot pattern PT. Alternatively, the user can click the input text button K2 to input text and convert the text into a dot pattern PT. Alternatively, the user can click the select photo button K3 to select a photo and convert the photo into a dot pattern PT. These texts or photos can be binarized first, and then the pixels can be merged to obtain a binarized pattern with the same resolution as the LED matrix. The lattice pattern PT can be obtained according to the binarization pattern. The set dot pattern PT is temporarily stored in the memory 130 .

Please refer to FIG. 5 , which illustrates a dot pattern PT and an LED matrix 240 according to an embodiment. The dot matrix pattern PT set by the user has a length L1 and a width W1. The LED matrix 240 has a fixed predetermined length L0 and a predetermined width W0. When the length L1 of the dot matrix pattern PT does not exceed the predetermined length L0 and the width W1 does not exceed the predetermined width W0, the dot matrix pattern PT is directly displayed in the form of a still image.

Next, in step S302, the processor 110 of the mobile device 100 determines whether the length L1 of the dot pattern PT is greater than the predetermined length L0.

Then, in steps S303 and S304, the processor 110 of the mobile device 100 determines whether the width W1 of the dot pattern PT is greater than the predetermined width W0.

If the length L1 of the dot pattern PT is greater than the predetermined length L0 and the width W1 of the dot pattern PT is greater than the predetermined width W0, proceed to step S305; if the length L1 of the dot pattern PT is greater than the predetermined length L0 and the width W1 of the dot pattern PT is less than or equal to the predetermined width W0, then go to step S306; if the length L1 of the dot pattern PT is less than or equal to the predetermined length L0 and the width W1 of the dot pattern PT is greater than the predetermined width W0, then go to step S307; If the length L1 is less than or equal to the predetermined length L0 and the width W1 of the dot matrix pattern PT is less than or equal to the predetermined width W0, the process proceeds to step S308.

In step S305, the processor 110 of the mobile device 100 controls the user interface 140 to display a size setting error message. Please refer to FIG. 6, which illustrates the case where the length L1 of the dot pattern PT is greater than the predetermined length L0 and the width W1 of the dot pattern PT is greater than the predetermined width W0. In the case of FIG. 6 , no matter how the dot pattern PT moves, it cannot be displayed normally on the LED matrix 240 , so a size setting error message is directly displayed to remind the user that the dot pattern PT needs to be reset.

In step S306, the processor 110 of the mobile device 100 sets the movement direction MD to be the direction parallel to the length L1. Please refer to FIG. 7, which illustrates the case where the length L1 of the dot pattern PT is greater than the predetermined length L0 and the width W1 of the dot pattern PT is less than or equal to the predetermined width W0. In the case of FIG. 7 , the moving direction MD can be set as the direction parallel to the length L1 , so that the dot pattern PT is displayed on the LED matrix 240 in the form of an Animated Image. In the dynamic picture mode, the dot pattern PT moves with time. At each time point, the LED matrix 240 displays only part of the dot pattern PT. After one cycle, each part of the dot pattern PT is displayed.

In step S307, the processor 110 of the mobile device 100 sets the movement direction MD to be the direction parallel to the width W1. Please refer to FIG. 8, which illustrates the case where the length L1 of the dot pattern PT is less than or equal to the predetermined length L0 and the width W1 of the dot pattern PT is greater than the predetermined width W0. In the case of FIG. 8, the moving direction MD can be set to be parallel to the direction of the width W1, so that the dot pattern PT is displayed on the LED matrix 240 in the form of an Animated Image. In the dynamic picture mode, the dot pattern PT moves with time. At each time point, the LED matrix 240 displays only part of the dot pattern PT. After one cycle, each part of the dot pattern PT is displayed.

In step S308, the processor 110 of the mobile device 100 disables the movement direction MD, so that the smart speaker 200 directly displays the dot pattern PT in the form of a still image. Please refer to FIG. 9, which illustrates a case where the length L1 of the dot pattern PT is less than or equal to the predetermined length L0 and the width W1 of the dot pattern PT is less than or equal to the predetermined width W0. In the case of FIG. 9 , the moving direction MD is disabled, and the dot pattern PT is displayed in the center of the LED matrix 240 as a static picture. In the still picture mode, the dot pattern PT is stationary over time. At each time point, the LED matrix 240 displays the entire dot pattern PT.

Next, in step S309 , the transmission module 120 of the mobile device 100 is connected to the receiving module 220 of the smart speaker 200 . This step can be performed automatically after steps S305, S306, S307, and S308 are performed. Alternatively, this step can also be performed when the application (App) is opened.

Then, in step S310 , the moving direction MD and the dot pattern PT are transmitted by the transmission module 120 of the mobile device 100 .

Next, in step S311 , the moving direction MD and the dot pattern PT are received by the receiving module 220 of the smart speaker 200 and stored in the memory 230 .

Then, in step S312, the controller 210 of the smart speaker 200 controls the LED matrix 240 to display the dot pattern PT according to the moving direction MD. Please refer to FIG. 10, which illustrates a movement method according to an embodiment. As shown in FIG. 10, the dot matrix pattern PT has a total of 6X columns, and the LED matrix 240 can only display 4X columns. At the time point T1, the LED matrix 240 displays the 1st to 4Xth columns of the dot pattern PT; at the time point T2, the dot pattern PT moves up by X columns, so that the LED matrix 240 displays the 1st+Xth column of the dot pattern PT Columns to 5Xth columns; at time point T3, the dot matrix pattern PT moves up by X columns again, so that the LED matrix 240 displays the 1+2Xth column to 6Xth column of the dot matrix pattern PT; at time point T4, the dot matrix pattern PT The X columns are moved downward, so that the LED matrix 240 displays the 1+X column to the 5X column of the dot pattern PT. That is to say, the controller 210 of the smart speaker 200 moves back and forth to display the dot pattern PT at a speed of moving X columns per unit time according to the moving direction MD.

Please refer to FIG. 11, which illustrates a movement method according to another embodiment. As shown in FIG. 11, the dot matrix pattern PT has a total of 6X columns, and the LED matrix 240 can only display 4X columns. At the time point T1, the LED matrix 240 displays the 1st to 4Xth columns of the dot pattern PT; at the time point T2, the dot pattern PT moves up by X columns, so that the LED matrix 240 displays the 1st+Xth column of the dot pattern PT Columns to 5Xth columns; at time point T3, the dot matrix pattern PT moves up by X columns again, so that the LED matrix 240 displays the 1+2Xth column to 6Xth column of the dot matrix pattern PT; at time point T4, the dot matrix pattern PT Continue to move up the X columns, so that the LED matrix 240 displays the 1+3X column to the 6X column and the first column to the X column of the dot pattern PT. That is, the controller 210 of the smart speaker 200 cyclically displays the dot pattern PT at a speed of moving X columns per unit time according to the moving direction MD.

In another embodiment, the length L1 or the width W1 of the dot matrix pattern PT set by the user may be quite long, and it may take a long time for the LED matrix 240 to display all the dot matrix patterns PT, so the following The flow chart speeds up the display of the dot pattern PT.

Please refer to FIG. 12 , which shows a flowchart of a method for dynamically adjusting the dot matrix pattern of the smart speaker 200 according to another embodiment. Steps S401-S408 are similar to steps S301-S308, and the description is not repeated here.

In step S403, it is determined that the length L1 of the dot matrix pattern PT is greater than the predetermined length L0 and the width W1 of the dot matrix pattern PT is less than or equal to the predetermined width W0, and in step S406, after setting the moving direction MD to be the direction parallel to the length L1, enter the Step S409. In step S409, the processor 110 of the mobile device 100 determines whether the multiple of the length L1 of the dot pattern PT relative to the predetermined length L0 exceeds a predetermined size multiple. The predetermined size multiple is, for example, 1.3 times, 1.5 times, 2 times, and 2.5 times. If the multiple of the length L1 of the dot pattern PT relative to the predetermined length L0 exceeds the predetermined size multiple, the process proceeds to step S411.

In step S411, the processor 110 of the mobile device 100 increases a moving speed MS by a predetermined speed multiple. The predetermined speed multiple is, for example, 1.3 times, 1.5 times, 2 times, 2.5 times.

In step S404, it is determined that the length L1 of the dot pattern PT is less than or equal to the predetermined length L0 and the width W1 of the dot pattern PT is greater than the predetermined width W0, and in step S407, the moving direction MD is set to be the direction parallel to the width W1, and then enter the Step S410. In step S410, the processor 110 of the mobile device 100 determines whether the multiple of the width W1 of the dot pattern PT relative to the predetermined width W0 exceeds the predetermined size multiple. If the multiple of the width W1 of the dot pattern PT with respect to the predetermined width W0 exceeds the predetermined size multiple, the process proceeds to step S412.

In step S412, the processor 110 of the mobile device 100 increases the moving speed MS by a predetermined speed multiple.

Next, in step S413 , the transmission module 120 of the mobile device 100 is connected to the receiving module 220 of the smart speaker 200 .

Then, in step S414, the transmission module 120 of the mobile device 100 transmits the moving direction MD, the moving speed MS and the dot pattern PT.

Next, in step S415 , the receiving module 220 of the smart speaker 200 receives the moving direction MD, the moving speed MS and the dot pattern PT, and stores them in the memory 230 .

Then, in step S416, the controller 210 of the smart speaker 200 controls the LED matrix 240 to display the dot pattern PT according to the moving direction MD and the moving speed MS.

Please refer to FIG. 13, which illustrates an example in which the moving speed MS is doubled. As shown in FIG. 13, the dot matrix pattern PT has a total of 6X columns, and the LED matrix 240 can only display 4X columns. At time point T1, the LED matrix 240 displays the 1st to 4Xth columns of the dot pattern PT; at time point T2, the dot pattern PT moves upward by 2X columns, so that the LED matrix 240 displays the 1+2Xth column of the dot pattern PT Columns to 6Xth columns; at time point T3, the dot matrix pattern PT moves downward by 2X columns, so that the LED matrix 240 displays the 1st to 4Xth columns of the dot matrix pattern PT; at time point T4, the dot matrix pattern PT moves upwards 2X columns, so that the LED matrix 240 displays the 1+2X column to the 6X column of the dot pattern PT. That is to say, the controller 210 of the smart speaker 200 cyclically displays the dot pattern PT at a speed of moving 2X columns per unit time according to the moving direction MD.

Please refer to FIG. 14, which illustrates another example in which the moving speed MS is increased by 2 times. As shown in FIG. 14, the dot matrix pattern PT has a total of 6X columns, and the LED matrix 240 can only display 4X columns. At time point T1, the LED matrix 240 displays the 1st to 4Xth columns of the dot pattern PT; at time point T2, the dot pattern PT moves upward by 2X columns, so that the LED matrix 240 displays the 1+2Xth column of the dot pattern PT row to row 6X; at time point T3, the dot matrix pattern PT is moved up again by 2X columns, so that the LED matrix 240 displays the 1+4X column to the 6X column and the 1X column to the 2X column of the dot matrix pattern PT; At time point T4, the dot pattern PT continues to move upward by 2X columns, so that the LED matrix 240 displays the first to 4X columns of the dot pattern PT. That is to say, the controller 210 of the smart speaker 200 cyclically displays the dot pattern PT at a speed of moving 2X columns per unit time according to the moving direction MD.

In this way, when the length L1 or the width W1 of the dot pattern PT set by the user is relatively long, the display of the dot pattern PT can be accelerated.

According to the above-mentioned embodiment, the mobile device 100 can install an application program (App), and the application program allows the user to set the dot pattern PT. The mobile device 100 further determines, according to the size of the dot pattern PT, that the dot pattern PT is too large and requires a mobile display, so the moving direction MD and the moving speed MS are set. After the mobile device 100 transmits the dot pattern PT and its moving direction MD and moving speed MS to the smart speaker 200 , the smart speaker 200 can display the dot pattern PT according to the moving direction MD and moving speed MS. In this way, the interactive experience between the smart speaker 200 and the user can be enriched.
