[0081] Please refer to Figure 1 and Figure 2 , Figure 1 which is a schematic external view of the electronic device 100 in the closed state P1, Figure 2 and

[0082] Please refer to Figure 3 , Figure 4A , Figure 5 and Figure 6 , Figure 3 which is a partial exploded view of the electronic device 100, Figure 4AA partial external view schematic diagram of the electronic device 100 in the closed state P1. Figure 5 A partial external view schematic diagram of the back of the electronic device 100 in the unfolded state P2. Figure 6 A partial external view schematic diagram of the front of the electronic device 100 in the unfolded state P2. The rotation shaft module 3 includes a main shaft member 31, a transmission assembly 34, and a multimedia assembly 35. The main shaft member 31 of the rotation shaft module 3 is pivotally connected to the first body 1 or the second body 2, and is adapted to enable the second body 2 to rotate relative to the first body 1 with the main shaft member 31 as the center. The second body 2 and the main shaft member 31 are adapted to rotate along the first rotation directions R1, R1'. The transmission assembly 34 is rotatably connected to the main shaft member 31. The multimedia assembly 35 is connected to the transmission assembly 34. The multimedia assembly 35 is adapted to rotate relative to the first body 1 and the second body 2 through the main shaft member 31, and the multimedia assembly 35 is adapted to be driven by the transmission assembly 34 to rotate along the second rotation directions R2, R2'. The first rotation direction R1 is opposite to the second rotation direction R2, and the first rotation direction R1' is opposite to the second rotation direction R2'. The so-called first rotation direction R1 is the same as the rotation direction in which the second body 2 is opened relative to the first body 1, and the first rotation direction R1' is the same as the rotation direction in which the second body 2 is closed relative to the first body 1, but it is not limited thereto.

[0083] In some embodiments, when the user applies a force to the second body 2 to cause the second body 2 to unfold relative to the first body 1 along the first rotation direction R1, the main shaft member 31 rotates in the first rotation direction R1. The main shaft member 31 drives the transmission assembly 34, so that the multimedia assembly 35 rotates in the second rotation direction R2. When the user applies a force to the second body 2 to cause the second body 2 to close relative to the first body 1 in the first rotation direction R1', the main shaft member 31 rotates in the first rotation direction R1'. The main shaft member 31 drives the transmission assembly 34, so that the multimedia assembly 35 rotates in the second rotation direction R2'. Thus, by operating the second body 2, the multimedia assembly 35 can rotate in the opposite direction to the second body 2 through the main shaft member 31.

[0084] In some embodiments, the main shaft member 31 includes a rotating rod 32, a first fixing plate 331, and a second fixing plate 332. The first fixing plate 331 and the second fixing plate 332 are disposed at one end of the rotating rod 32. The first fixing plate 331 and the second fixing plate 332 are respectively connected to the first body 1 and the second body 2. The second body 2 includes a first housing 22, and the rotating rod 32 is sleeved on the first housing 22. When the second body 2 rotates, the second fixing plate 332 of the second body 2 rotates relative to the first fixing plate 331 with the rotating rod 32, and the first housing 22 and the rotating rod 32 rotate synchronously. In some embodiments, the first housing 22 can be disposed on the first body 1 and the rotating rod 32 is sleeved on the first housing 22, and the first body 1 can drive the rotating rod 32 to rotate, but it is not limited thereto.

[0085] In some embodiments, the rotating rod 32 includes a first transmission member 324', the transmission assembly 34 includes a second transmission member 344', the second housing 342 is a hollow tube body and is fixed to the first body 1, and the second transmission member 344' is disposed within the second housing 342. The first housing 22 and the second housing 342 are arranged in sequence along the first axis X direction.

[0086] In some embodiments, the multimedia assembly 35 includes a third housing 352, a multimedia element 353, and a third transmission member 354'. The third housing 352 is a hollow tube body, the multimedia element 353 is fixed within the housing 352 (using the same number as the third housing 352), the third transmission member 354' is disposed within the third housing 352, the third transmission member 354' is disposed at one end of the multimedia element 353, the multimedia element 353 is adapted to rotate relative to the first body 1 and the second body 2 through the third transmission member 354', and the multimedia element 353 and the third housing 352 can rotate simultaneously along the second rotation directions R2, R2'. The first housing 22, the second housing 342, and the third housing 352 are arranged in sequence along the first axis X direction. The multimedia element 353 may be, but is not limited to, a speaker, a lens, or a microphone. In some embodiments, taking the multimedia element 353 as a speaker as an example, a plurality of sound outlet holes 3521 are provided on the outer surface of the housing 352 (using the same number as the third housing 352), and the multimedia element 353 includes a sound outlet portion 3531, and the sound outlet portion 3531 faces each of the sound outlet holes 3521.

[0087] In some embodiments, the above-mentioned rotating shaft module 3 may be two groups, which are respectively disposed on both sides of the first body 1 and connected to the second body 2. With this design, the second body 2 can be stably unfolded or closed relative to the first body 1. In some embodiments, two multimedia elements 353 are respectively disposed on both sides of the third housing 352 and are respectively connected to the two main shaft members 31. In some embodiments, the first transmission member 324', the second transmission member 344', and the third transmission member 354' may be bevel gears, but are not limited thereto.

[0088] Upon assembly, the rotating rod 32 is sleeved on the first housing 22. The first transmission member 324' at one end of the rotating rod 32 is disposed within the second housing 342 and meshes with the second transmission member 344'. The multimedia component 353 is disposed within the third housing 352, and the third transmission member 354' is disposed on the second housing 342 and meshes with the second transmission member 344'. The first transmission member 324' and the third transmission member 354' respectively protrude from the rotating rod 32 and the multimedia component 353 towards the second transmission member 344', and are respectively meshed on both sides of the second transmission member 344' and disposed within the second housing 342. In some embodiments, when the second body 2 is unfolded from the closed state P1 relative to the first body 1, the second body 2 will drive the main shaft member 31 to rotate in the first rotation direction R1 while rotating, causing the first transmission member 324' of the main shaft member 31 to rotate in the first rotation direction R1, which in turn drives the second transmission member 344' to rotate in the third rotation direction R3. The second transmission member 344' drives the third transmission member 354' of the multimedia assembly 35 to rotate in the second rotation direction R2. When the third transmission member 354' rotates, the third transmission member 354' will drive the multimedia component 353 and the third housing 352 to rotate synchronously. When the second body 2 is closed from the unfolded state P2 relative to the first body 1, the second body 2 drives the main shaft member 31 and the first transmission member 324' to rotate in the first rotation direction R1', the first transmission member 324' drives the second transmission member 344' to rotate in the third rotation direction R3', and simultaneously drives the third transmission member 354' and the third housing 352 to rotate in the second rotation direction R2'. Thus, when the second body 2 is actuated, the third housing 352 rotates in the second rotation directions R2, R2' opposite to the first rotation directions R1, R1'. With this design, when the electronic device 100 is in the unfolded state P2, the sound outlet hole 3521 is adjacent to a surface 1a of the first body 1. When the electronic device 100 is in the closed state P1, the sound outlet hole 3521 is away from the surface 1a of the first body 1. The sound outlet hole 3521 can face the user when the electronic device 100 is in the unfolded state P2, and is away from the first body 1 and the second body 2 and exposed to the external space when the electronic device 100 is in the closed state P1.

[0089] In some embodiments, the ratio of the rotation angle of the main shaft member 31 in the first rotation direction R1 to the rotation angle of the multimedia component 353 in the second rotation direction R2 can be substantially 1:1, 1:2, or 2:1. Moreover, the ratio of the rotation angle of the main shaft member 31 to the rotation angle of the multimedia component 353 can be adjusted according to the gear ratios of the first transmission member 324', the second transmission member 344', and the third transmission member 354'.

[0090] In some embodiments, the outer diameter of the second transmission member 344' is greater than the outer diameters of the first transmission member 324' and the third transmission member 354'. The first rotation directions R1, R1' of the first transmission member 324' and the second rotation directions R2, R2' of the third transmission member 354' respectively have an angular relationship with the third rotation direction R3, R3' of the second transmission member 344'. More specifically, the first rotation directions R1, R1' and the second rotation directions R2, R2' are respectively perpendicular to the third rotation direction R3, R3'.

[0091] Please also refer to Figure 4B , Figure 4B which is a partial external view schematic diagram of the electronic device 100 in the closed state P1. In some embodiments, one end of the multimedia component 353 can be connected to the first fixing plate 331, the second fixing plate 332, and a rotating shaft (not shown in the figure). When the user rotates the second body 2, the rotating shaft drives the third transmission member 354' of the multimedia component 353 and the third housing 352 to rotate synchronously. The third transmission member 354' drives the second transmission member 344' and in turn drives the first transmission member 324'. With this configuration, the functions of the above embodiments can also be achieved. That is, the sound outlet holes 3521 of the multimedia component 353 can face the user when the electronic device 100 is in the unfolded state P2, and can be away from the first body 1 and the second body 2 and exposed to the external space when the electronic device 100 is in the closed state P1, which will not be elaborated here.

[0092] Please refer to Figure 3 and Figure 7A , Figure 7A which is Figure 1 a partial side view schematic diagram marking the position A - A, with the electronic device 100 in the closed state P1. Figure 7B which is Figure 7A a partial side view schematic diagram of the perspective of the electronic device 100 unfolded by about 45 degrees, Figure 7C which is Figure 7A a partial side view schematic diagram of the perspective of the electronic device 100 unfolded by about 130 degrees. In some embodiments, when the user closes the second body 2 of the electronic device 100 relative to the first body 1, the sound output part 3531 of the multimedia component 353 is away from the surface 1a of the first body 1 and faces the external space of the first body 1. The sound source of the sound output part 3531 emits sound towards the external space of the first body 1. And the sound output part 3531 has a sound output direction S, and there is a first angle A1 between the sound output direction S and the surface 1a (the second axis Y) of the first body 1, and the first angle A1 is between 150 degrees and 240 degrees.

[0093] Please refer to Figure 7B, in some embodiments, when the user unfolds the second body 2 of the electronic device 100 relative to the first body 1, there is an included angle α between the first body 1 and the second body 2. When the included angle α is about 45 degrees, the multimedia component 353 rotates along the second rotation direction R2 such that the sound-emitting part 3531 faces a surface 2a of the second body 2, and the sound source of the sound-emitting part 3531 can rebound to the user through the surface 1a of the first body 1 and the surface 2a of the second body 2. Here, there is a second angle A2 between the sound-emitting direction S of the sound-emitting part 3531 and the surface 1a (second axis Y) of the first body 1, and the second angle A2 is between 100 degrees and 190 degrees.

[0094] Please refer to Figure 7C , in some embodiments, when the included angle α is about 130 degrees, there is a third angle A3 between the sound-emitting direction S of the sound-emitting part 3531 and the surface 1a (second axis Y) of the first body 1, and the third angle A3 is between 15 degrees and 105 degrees, such as 45 degrees or 55 degrees, so that the sound-emitting part 3531 is adjacent to the surface 1a of the first body 1 and faces the user. That is, the sound source of the sound-emitting part 3531 emits sound towards the user.

[0095] Thus, when the electronic device 100 is in the unfolded state P2, the sound-emitting part 3531 of the multimedia component 353 can face the user, or when in the closed state P1, the sound-emitting part 3531 of the multimedia component 353 can face the outside of the electronic device 100, effectively releasing the sound source and providing a good auditory experience.

[0096] Refer to Figure 6A , Figure 6A is a partial front external view schematic diagram of the electronic device 100 in the unfolded state P2, and the multimedia component 353 is in the state of a camera lens. In some embodiments, taking the multimedia component 353 as a camera lens as an example, the multimedia assembly 35 includes a housing 352 (using the same number as the third housing 352), a multimedia component 353, and an opening part 3522. The opening part 3522 is arranged on the outer surface of the housing 352, the multimedia component 353 is arranged inside the housing 352, and the camera lens of the multimedia component 353 is exposed to the external space through the opening part 3522. The opening part 3522 is adapted to move away from or close to the surface 1a of the first body 1 through the rotation shaft module 3. The opening part 3522 can face the user when the electronic device 100 is in the unfolded state P2, and the camera lens of the multimedia component 353 is used for photography.

[0097] In some embodiments, the second body 2 rotates relative to the first body 1 to a closed state P1 or an unfolded state P2. When the second body 2 is in the closed state P1, the opening portion 3522 of the multimedia component 353 is away from the surface 1a of the first body 1. When the second body 2 is in the unfolded state P2, the opening portion 3522 of the multimedia component 353 is adjacent to the surface 1a of the first body 1. The opening portion 3522 of the multimedia component 353 forms an angle with the surface 1a of the first body 1 when in the unfolded state P2, and the angle is between 100 degrees and 190 degrees. This angle is the same as the second angle A2 in the foregoing embodiments and will not be elaborated herein.

[0098] Please refer to Figures 8 to 10 , Figure 8 a partial exploded view of the electronic device 100, Figure 9 a partial external view of the back surface of the electronic device 100 when unfolded, Figure 10 a partial external view of the front surface of the electronic device 100 when unfolded. In some embodiments, one end of the rotating rod 32 is connected to the first fixing plate 331 and the second fixing plate 332, and a first transmission member 324” is provided at the other end. The transmission assembly 34 includes a second housing 342, transmission rods 3431, 3432 located inside the second housing 342, and second transmission members 361, 362 that mesh with each other. The transmission rod 3431 and the transmission rod 3432 are in thread engagement and are interlocked with each other. The second transmission members 361, 362 respectively have the transmission rods 3431, 3432, and the transmission rod 3431 of one second transmission member 361 meshes with the transmission rod 3432 of the other second transmission member 362. The second transmission members 361, 362 are respectively provided on the transmission rods 3431, 3432. The second transmission member 361 extends along the first axis X from the transmission rod 3431 towards the main shaft member 31 and meshes with the first transmission member 324”; the second transmission member 362 extends along the -X direction opposite to the first axis X from the transmission rod 3432 towards the multimedia assembly 35 and meshes with the third transmission member 354”. In some embodiments, the outer diameters of the transmission rods 3431, 3432 are larger than the outer diameters of the second transmission members 361, 362. In some embodiments, the transmission rods 3431, 3432 are in tooth engagement with each other, but this is not limiting.

[0099] In some embodiments, the multimedia component 35 includes a third housing 352, a multimedia element 353, and a third transmission member 354". The third housing 352 is a hollow tube, the multimedia element 353 is fixedly disposed within the third housing 352, and one end of the third transmission member 354" is connected to the second transmission member 362; the other end of the third transmission member 354" is connected to the multimedia element 353, and the multimedia element 353 and the third housing 352 can rotate simultaneously along the second rotation directions R2, R2'. The first housing 22, the second housing 342, and the third housing 352 are arranged in sequence along the first axis X direction.

[0100] During assembly, the rotating rod 32 is sleeved on the first housing 22, and the first transmission member 324" located at one end of the rotating rod 32 is disposed within the second housing 342 and meshes with the second transmission member 361. The multimedia element 353 is disposed within the third housing 352, and the third transmission member 354" is disposed within the second housing 342 and meshes with the second transmission member 362.

[0101] In some embodiments, when the second body 2 is unfolded from the closed state P1 relative to the first body 1, the second body 2 will drive the main shaft member 31 to rotate in the first rotation direction R1 while rotating, so that the first transmission member 324" of the main shaft member 31 rotates in the first rotation direction R1, driving the second transmission member 361 to rotate in the fourth rotation direction R4 and simultaneously driving the transmission rod 3431 to rotate in the fourth rotation direction R4; since the transmission rod 3431 is linked with the transmission rod 3432, the transmission rod 3431 drives the transmission rod 3432 to rotate in the fifth rotation direction R5, causing the second transmission member 362 to rotate in the fifth rotation direction R5 at the same time, and linking the third transmission member 354" of the multimedia component 35 to rotate in the second rotation direction R2. When the third transmission member 354" rotates, the third transmission member 354" will drive the multimedia element 353 and the third housing 352 to rotate synchronously. When the second body 2 is closed from the unfolded state P2 relative to the first body 1, the second body 2 drives the main shaft member 31 and the first transmission member 324" to rotate in the first rotation direction R1', the first transmission member 324" drives the second transmission member 361 to rotate in the fourth rotation direction R4', and the second transmission member 361 simultaneously drives the transmission rod 3431 to rotate in the fourth rotation direction R4'; the transmission rod 3431 drives the transmission rod 3432 to rotate in the fifth rotation direction R5' and simultaneously drives the second transmission member 362 to rotate in the fifth rotation direction R5', and the second transmission member 362 drives the third transmission member 354" and the third housing 352 to rotate in the second rotation direction R2'.
