Please refer to FIG. 1, which shows a schematic diagram of an electronic device 100 according to an embodiment. The electronic device 100 includes a housing 110 and an active pen 120. The active pen 120 is inserted into a socket 110h of the housing 110. After the active pen 120 is inserted, the user can rotate the active pen 120 forward and backward to control the electronic device 100. For example, the user can rotate the active pen 120 to adjust the volume adjustment bar B1.

The active pen 120 includes a pen tip 121, a pen body 122 and a pen tail 123. When the active pen 120 is inserted into the socket 110h, the housing 110 exposes the pen tail 123. Please refer to Figure 2, which shows a cross-sectional view of the housing 110 and the pen tail 123 of Figure 1 along the section line 2-2'. The upper surface 111 of the housing 110 has an opening 111h to expose the pen tail 123. The pen tail 123 has a concave-convex surface 123s to increase friction. The concave-convex surface 123s is formed, for example, by a plurality of ribs or notches. The user can touch the concave-convex surface 123s with a finger to rotate the active pen 120. For example, these ribs or notches can be substantially parallel to the extension direction of the pen body 122, so as to facilitate the user to rotate the active pen 120 with the extension direction of the pen body 122 as the axis.

In addition, as shown in FIG. 2, the concave-convex surface 123s of the pen tail 123 is not higher than the upper surface 111 of the housing 110, so that when the electronic device 100 is covered with a display panel, the concave-convex surface 123s of the pen tail 123 can be prevented from touching the display panel.

In one embodiment, the active pen 120 can rotate forward or backward. Alternatively, in another embodiment, the active pen 120 can be limited to rotate in a certain direction. In one embodiment, the rotation range of the active pen 120 can be unlimited (d can rotate infinitely in the same direction). Alternatively, in another embodiment, the rotation range of the active pen 120 can be limited to 360 degrees.

Please refer to FIG. 3, which illustrates an example of the engagement between the active pen 120 and the socket 110h according to an embodiment. The pen body 122 of the active pen 120 has at least one annular groove 122g. The annular groove 122g surrounds the pen body 122 in a full circle. The electronic device 100 further includes at least one elastic pin 130. The elastic pin 130 is disposed in the socket 110h (shown in FIG. 1). When the active pen 120 is inserted into the socket 110h, the elastic pin 130 can be engaged with the annular groove 122g to position the active pen 120.

In one embodiment, the electronic device 100 may be provided with two sets of elastic pins 130, one set of elastic pins 130 is close to the pen tip 121, and the other set of elastic pins 130 is close to the pen tail 123. The number of elastic pins 130 in each set is, for example, 1, 2, 3, or more than 3. These elastic pins 130 may be symmetrically arranged around the pen body 122 to evenly apply force to the active pen 120 and hold it stably.

As shown in FIG. 3 , the width W1 of the annular groove 122g is greater than the width W2 of the elastic ejector pin 130. In this way, the elastic ejector pin 130 can naturally fall into the lowest point of the annular groove 122g. In addition, the contact area between the elastic ejector pin 130 and the annular groove 122g can be minimized to reduce friction during rotation.

Please refer to FIG. 4, which shows a side view of an active pen 120 and a sleeve 140 according to an embodiment. The electronic device 100 further includes a sleeve 140. The sleeve 140 is disposed inside the socket 110h. The tip 121 of the active pen 120 has a rough surface 121s. The rough surface 121s is located at the tip 121 of the active pen 120. The rough surface 121s is composed of, for example, a plurality of ribs or notches. These ribs or notches are, for example, parallel to the extension direction of the pen body 122.

Please refer to Figure 5, which shows a schematic diagram of the tip 121 of the active pen 120 according to Figure 4 being inserted into the sleeve 140. When the tip 121 of the active pen 120 is inserted into the sleeve 140, the active pen 120 contacts the inner wall 140w of the sleeve 140 with the rough surface 121s. With the rough surface 121s, when the active pen 120 rotates, the sleeve 140 can be driven to rotate together.

In one embodiment, the rough surface 121s of the active pen 120 is conical, and the inner wall 140w of the marking sleeve 140 is also conical, so that the rough surface 121s and the inner wall 140w can fit each other. In addition, the conical inner wall 140w can effectively limit the insertion depth of the active pen 120.

Please refer to FIG. 6, which shows a schematic diagram of a sleeve 140, a convex rod assembly 150 and a deformation sensing assembly 160 according to an embodiment. The electronic device 100 further includes a convex rod assembly 150 and a deformation sensing assembly 160. As shown in FIG. 6, the convex rod assembly 150 includes, for example, a first convex rod 151, and the deformation sensing assembly 160 includes, for example, a first pressure sensing element 161, a second pressure sensing element 162, a third pressure sensing element 163 and a fourth pressure sensing element 164. The convex rod assembly 150 is disposed on an outer surface of the sleeve 140. The convex rod assembly 150 rotates together with the sleeve 140. The deformation sensing assembly 160 is disposed outside the sleeve 140. The deformation sensing assembly 160 is located within the rotational travel of the cam assembly 150 to sense the rotation of the cam assembly 150.

Please refer to FIG. 7, which shows a top view of a sleeve 140, a cam assembly 150, and a deformation sensing assembly 160 according to an embodiment. The cross section of the first cam 151 of the cam assembly 150 is, for example, an isosceles triangle. The first pressure sensing element 161, the second pressure sensing element 162, the third pressure sensing element 163, and the fourth pressure sensing element 164 are, for example, plate-like structures. The first pressure sensing element 161, the second pressure sensing element 162, the third pressure sensing element 163, and the fourth pressure sensing element 164 are substantially evenly located at four positions outside the sleeve 140, for example, at the 0 degree position, the 90 degree position, the 180 degree position, and the 270 degree position, respectively. When the sleeve 140 rotates, the first protruding rod 151 will push the first pressure sensing element 161, the second pressure sensing element 162, the third pressure sensing element 163 or the fourth pressure sensing element 164.

Please refer to Figure 8A, which illustrates an example of the first protruding rod 151 pushing the second pressure sensing element 162 in a clockwise direction. The hardness of the protruding rod assembly 150 is higher than the hardness of the deformation sensing assembly 160. When the first protruding rod 151 pushes the second pressure sensing element 162 in a clockwise direction, the second pressure sensing element 162 is concave downward. Please refer to Figure 8B, which illustrates an example of the charge distribution of the second pressure sensing element 162 in a concave downward situation. When the second pressure sensing element 162 is in a concave downward situation, negative charges will be gathered above the piezoelectric material, and positive charges will be gathered below the piezoelectric material, and a positive pressure deformation sensing signal SNi will be output.

Please refer to FIG. 8A and Table 1 below. When the user rotates the active pen 120 90 degrees clockwise, the positive pressure deformation sensing signal SNi is output by the second pressure sensing element 162. When the user rotates the active pen 120 180 degrees clockwise, the positive pressure deformation sensing signal SNi is output by the second pressure sensing element 162 and the third pressure sensing element 163 in sequence. When the user rotates the active pen 120 180 degrees clockwise, the positive pressure deformation sensing signal SNi is output by the second pressure sensing element 162 and the third pressure sensing element 163 in sequence. When the active pen 120 rotates 270 degrees clockwise, the positive pressure deformation sensing signal SNi will be outputted by the second pressure sensing element 162, the third pressure sensing element 163 and the fourth pressure sensing element 164 in sequence; when the user rotates the active pen 120 360 degrees clockwise, the positive pressure deformation sensing signal SNi will be outputted by the second pressure sensing element 162, the third pressure sensing element 163, the fourth pressure sensing element 164 and the first pressure sensing element 161 in sequence. In other words, the rotation of the active pen 120 can be analyzed based on these deformation signals SNi.

Please refer to FIG. 9A, which illustrates an example of the first convex rod 151 pushing the second pressure sensing element 162 in a counterclockwise direction. When the first convex rod 151 pushes the second pressure sensing element 162 in a counterclockwise direction, the second pressure sensing element 162 presents a concave upward situation. Please refer to FIG. 9B, which illustrates an example of the charge distribution of the second pressure sensing element 162 in a concave upward situation. When the second pressure sensing element 162 presents a concave upward situation, positive charges will be gathered above the piezoelectric material, and negative charges will be gathered below the piezoelectric material, and a negative pressure deformation sensing signal SNi will be output.

Please refer to FIG. 9A and Table 2 below. When the user rotates the active pen 120 counterclockwise by 90 degrees, the negative pressure deformation sensing signal SNi is output by the second pressure sensing element 162. When the user rotates the active pen 120 counterclockwise by 180 degrees, the negative pressure deformation sensing signal SNi is output by the second pressure sensing element 162 and the first pressure sensing element 161 in sequence. When the user rotates the active pen 120 counterclockwise by 180 degrees, the negative pressure deformation sensing signal SNi is output by the second pressure sensing element 162 and the first pressure sensing element 161 in sequence. When the active pen 120 rotates 270 degrees in the clockwise direction, the negative pressure deformation sensing signal SNi will be outputted by the second pressure sensing element 162, the first pressure sensing element 161 and the fourth pressure sensing element 164 in sequence; when the user rotates the active pen 120 counterclockwise by 360 degrees, the negative pressure deformation sensing signal SNi will be outputted by the second pressure sensing element 162, the first pressure sensing element 161, the fourth pressure sensing element 164 and the third pressure sensing element 163 in sequence. In other words, the rotation of the active pen 120 can be analyzed based on these deformation signals SNi.

In other words, the degree and direction of rotation of the active pen 120 can be analyzed through the deformation sensing signal SNi.

Please refer to Figure 10, which shows a schematic diagram of the sleeve 140, the convex rod assembly 250 and the deformation sensing assembly 160 according to another embodiment. The convex rod assembly 250 includes a first convex rod 251, a second convex rod 252 and a third convex rod 253. The first convex rod 251, the second convex rod 252 and the third convex rod 253 are arranged within a 90-degree range on the outer surface of the sleeve 140.

Please refer to FIG. 11, which shows a top view of the sleeve 140, the cam assembly 250, and the deformation sensing assembly 160 according to an embodiment. The cross-section of the first cam 251, the second cam 252, and the third cam 253 of the cam assembly 250 is, for example, an isosceles triangle. The angle between the first cam 251 and the second cam 252 is, for example, 22.5 degrees. The angle between the second cam 252 and the third cam 253 is, for example, 22.5 degrees. Please refer to Figure 11 and Table 1 below. When the user rotates the active pen 120 22.5 degrees clockwise, the positive pressure deformation sensing signal SNi will be output by the second pressure sensing element 162; when the user rotates the active pen 120 45 degrees clockwise, the positive pressure deformation sensing signal SNi will be output twice by the second pressure sensing element 162; when the user rotates the active pen 120 67.5 degrees clockwise, the positive pressure deformation sensing signal SNi will be output three times by the second pressure sensing element 162; and so on. The degree of rotation can be analyzed by the number of times the second pressure sensing element 162 outputs the deformation sensing signal SNi, and the estimation accuracy can reach 22.5 degrees.

Please refer to FIG. 12, which shows a schematic diagram of the sleeve 140, the convex rod assembly 350 and the deformation sensing assembly 360 according to another embodiment. As shown in FIG. 12, the convex rod assembly 350 includes, for example, a first convex rod 351, a second convex rod 352, a third convex rod 353 and a fourth convex rod 354, and the deformation sensing assembly 360 includes, for example, a first pressure sensing element 361.

Please refer to FIG. 13, which shows a top view of the sleeve 140, the rod assembly 350 and the deformation sensing assembly 360 according to an embodiment. The cross-section of the first rod 351, the second rod 352, the third rod 353 and the fourth rod 354 of the rod assembly 350 is, for example, an isosceles triangle. The first rod 351, the second rod 352, the third rod 353 and the fourth rod 354 are substantially evenly disposed at four positions on the outer surface of the sleeve 140. In addition, the lengths of the first rod 351, the second rod 352, the third rod 353 and the fourth rod 354 are different. When the sleeve 140 rotates, the first protruding rod 351, the second protruding rod 352, the third protruding rod 353 or the fourth protruding rod 354 will push the first pressure sensing element 361.

Please refer to Figure 13, which illustrates an example of the first protrusion 351, the second protrusion 352, the third protrusion 353 or the fourth protrusion 354 pushing the first pressure sensing element 361 in a clockwise direction. The first protrusion 351, the second protrusion 352, the third protrusion 353 or the fourth protrusion 354 have different lengths, so when the first protrusion 351, the second protrusion 352, the third protrusion 353 or the fourth protrusion 354 pushes the first pressure sensing element 361, different degrees of deformation will be generated.

Please refer to FIG. 13 and Table 4 below. When the user rotates the active pen 120 clockwise by 90 degrees, the first protruding rod 351 pushes the first pressure sensing element 361 and outputs a corresponding positive pressure deformation sensing signal SNi. When the user rotates the active pen 120 clockwise by 180 degrees, the first protruding rod 351 and the fourth protruding rod 354 push the first pressure sensing element 361 in sequence and outputs a corresponding positive pressure deformation sensing signal SNi in sequence. When the user rotates the active pen 120 clockwise by 180 degrees, the first protruding rod 351 and the fourth protruding rod 354 push the first pressure sensing element 361 in sequence and outputs a corresponding positive pressure deformation sensing signal SNi in sequence. When the clockwise rotation is 270 degrees, the first protrusion 351, the fourth protrusion 354 and the third protrusion 353 will push the first pressure sensing element 361 in sequence, and output the corresponding positive pressure deformation sensing signal SNi in sequence; when the user rotates the active pen 120 clockwise by 270 degrees, the first protrusion 351, the fourth protrusion 354, the third protrusion 353 and the second protrusion 352 will push the first pressure sensing element 361 in sequence, and output the corresponding positive pressure deformation sensing signal SNi in sequence. In other words, according to these deformation signals SNi, the rotation of the active pen 120 can be analyzed.

Please refer to Figure 14, which shows a top view of the sleeve 140, the protruding rod assembly 450 and the deformation sensing assembly 360 according to one embodiment. The protruding rod assembly 450 includes protruding rods 450j arranged at different densities.

Please refer to FIG. 14 and Table 5 below. When the user rotates the active pen 120 clockwise by 90 degrees, one convex rod 450j pushes the first pressure sensing element 361 and outputs a positive pressure deformation sensing signal SNi. When the user rotates the active pen 120 clockwise by 180 degrees, three convex rods 450j push the first pressure sensing element 361 and output three positive pressure deformation sensing signals SNi. Signal SNi; when the user rotates the active pen 120 clockwise by 270 degrees, the six protruding rods 450j will push the first pressure sensing element 361 and output six positive pressure deformation sensing signals SNi; when the user rotates the active pen 120 clockwise by 360 degrees, the ten protruding rods 450j will push the first pressure sensing element 361 and output ten positive pressure deformation sensing signals SNi. In other words, the rotation of the active pen 120 can be analyzed based on the number of deformation signals SNi.

Please refer to Figures 15A-15B, which show schematic diagrams of a sleeve 540 according to another embodiment. The sleeve 540 has a slot 540h. The electronic device 500 further includes a resistance rod 571, a motor 572 and a gear set 573. The resistance rod 571 is inserted into the slot 540h. The gear set 573 is connected to the motor 572 and the resistance rod 571. The motor 572 drives the gear set 573 to rotate to change the depth of the resistance rod 571 inserted into the slot 540h. As shown in Figure 15A, the resistance rod 571 is inserted to the bottom of the slot 540h to provide more friction. As shown in Figure 15B, the resistance rod 571 is only inserted into half of the slot 540h to provide less friction. The magnitude of the friction can create different degrees of force feedback. The resistance rod 571 can also provide a vibrating touch by moving forward and backward.

Please refer to FIG. 16, which shows a block diagram of an electronic device 100 according to an embodiment. The electronic device 100 includes the elastic ejector pin 130, the protruding rod assembly 150, the deformation sensing assembly 160, a calibration unit 181, an analysis unit 182, a database 183, and a control unit 184. The calibration unit 181 is used to perform a calibration procedure. The analysis unit 182 is used to execute various analysis procedures. The database 183 is used to store various data. The control unit 184 is used to execute various control procedures. The calibration unit 181, the analysis unit 182, and/or the control unit 184 are, for example, a circuit, a chip, a circuit board, a processor, or a storage device for storing program codes. The database 183 is, for example, a memory, a hard drive or a cloud storage center. In this embodiment, after the active pen 120 is inserted into the jack, the control unit 184 activates the calibration unit 181 and the analysis unit 182 to analyze the rotation of the active pen 120 according to the deformation signals SNi and perform corresponding operations accordingly. The operation of each component is described in detail with a flowchart below.

Please refer to FIG. 17, which shows a flow chart of a control method of an electronic device 100 according to an embodiment. In step S110, the control unit 184 senses whether the active pen 120 is inserted into the socket 110h of the housing 110. For example, the control unit 184 can determine whether the elastic ejector pin 130 is engaged with the annular groove 122g of the active pen 120 based on the compression status signal S1 of the elastic ejector pin 130, so as to confirm whether the active pen 120 has been inserted into the socket 110h.

Alternatively, the annular groove 122g of the active pen 120 can be provided with an annular conductive sheet, and when the elastic ejector pin 130 is engaged with the annular groove 122g, a short circuit signal will be generated. The control unit 184 can know whether the elastic ejector pin 130 is engaged with the annular groove 122g of the active pen 120 through the short circuit signal S2 to confirm whether the active pen 120 has been inserted into the position of the socket 110h.

Next, in step S120, the control unit 184 activates the calibration unit 181 and the analysis unit 182. The calibration unit 181 and the analysis unit 182 are usually in a closed state or a dormant state until the control unit 184 transmits activation signals E1 and E2 to the calibration unit 181 and the analysis unit 182 respectively.

Then, in step S130, the calibration unit 181 executes the calibration procedure. When the calibration procedure starts, the screen of the electronic device 100 prompts the user to rotate 90 degrees, 180 degrees, 270 degrees, and 360 degrees clockwise (or counterclockwise), and the deformation signal SNi output by the deformation sensing component 160 is transmitted to the calibration unit 181. The calibration unit 181 generates a deformation signal and rotation comparison table TB according to the deformation signal SNi, and transmits it to the analysis unit 182.

Next, in step S140, according to the deformation of the deformation sensing component 160, the deformation signal SNi is output to the analysis unit 182.

Then, in step S150, the analysis unit 182 analyzes the rotation of the active pen 120 according to the deformation signal SNi.

Next, in step S160, the control unit 184 generates a control command CM according to the rotation condition of the active pen 120. For example, the rotation condition signal S3 provided by the analysis unit 182 to the control unit 184 is, for example, four conditions such as upward rotation at the first rotation speed, upward rotation at the second rotation speed, downward rotation at the first rotation speed, or downward rotation at the second rotation speed. The first rotation speed is higher than the second rotation speed. The control unit 184 can generate different control commands CM according to these four conditions of the rotation condition signal S3, such as double speed fast forward, single speed fast forward, double speed reverse, single speed reverse, etc.

According to the above embodiment, after the user inserts the active pen 120 into the socket 110h, the user can rotate the active pen 120 forward and backward to perform the required control on the electronic device 100, which is very convenient to use and meets the needs of the user.

In summary, although the present disclosure has been disclosed as above by the embodiments, it is not intended to limit the present disclosure. Those with ordinary knowledge in the technical field to which the present disclosure belongs can make various changes and modifications without departing from the spirit and scope of the present disclosure.
