In some embodiments, for example, the multimedia element 353 is a speaker, a plurality of sound emission holes 3521 are provided on an outer surface of the housing 352 (using the same serial number as the third housing 352), the multimedia element 353 includes a sound emission portion 3531, and the sound emission portion 3531 faces the sound emission holes 3521.

In some embodiments, the hinge module 3 may be divided into two groups which are respectively arranged on two sides of the first body 1 and are connected to the second body 2. In this design, the second body 2 may be stably unfolded or folded relative to the first body 1. In some embodiments, two multimedia elements 353 are respectively arranged on two sides of the third housing 352 and are respectively connected to 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. The disclosure is not limited thereto.

During assembly, the rotating rod 32 is sleeved in the first housing 22, and the first transmission member 324′ located at one end of the rotating rod 32 is arranged in the second housing 342 and is engaged with the second transmission member 344′. The multimedia element 353 is arranged in the third housing 352, and the third transmission member 354′ is arranged in the second housing 342 and is engaged with the second transmission member 344′.

In some embodiments, when the second body 2 is unfolded from the folded state P1 relative to the first body 1, the second body 2 may drive, while rotating, the main shaft member 31 to rotate in the first rotation direction R1, so that the first transmission member 324′ of the main shaft member 31 rotates in the first rotation direction R1 and links the second transmission member 344′ to rotate in a third rotation direction R3, and 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′ may drive the multimedia element 353 and the third housing 352 to rotate synchronously. When the second body 2 is folded 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 a third rotation direction R3′ and drives the third transmission member 354′ and the third housing 352 to rotate in the second rotation direction R2′. In this way, when the second body 2 moves, the third housing 352 rotates in the second rotation directions R2 and R2′ opposite to the first rotation directions R1 and R1′. In this design, when the electronic device 100 is in the unfolded state P2, the sound emission holes 3521 are close to a surface 1a of the first body 1; and when the electronic device 100 is in the folded state P1, the sound emission holes 3521 are away from the surface 1a of the first body 1. When the electronic device 100 is in the unfolded state P2, the sound emission holes 3521 may face the user, and when the electronic device 100 is in the folded state P1, the sound emission holes may be away from the first body 1 and the second body 2 and exposed to an external space.

In some embodiments, a ratio of an angle at which the main shaft member 31 rotates in the first rotation direction R1 to an angle at which the multimedia element 353 rotates in the second rotation direction R2 may be substantially 1:1, 1:2, or 2:1. In addition, the ratio of the rotation angle of the main shaft member 31 to the rotation angle of the multimedia element 353 may be adjusted according to gears of the first transmission member 324′, the second transmission member 344′, and the third transmission member 354′.

In some embodiments, an outer diameter of the second transmission member 344′ is greater than outer diameters of the first transmission member 324′ and the third transmission member 354′, and the first rotation directions R1 and R1′ of the first transmission member 324′ and the second rotation directions R2 and R2′ of the third transmission member 354′ respectively form an angle relative to the third rotation directions R3 and R3′ of the second transmission member 344′. In more detail, the first rotation directions R1 and R1′ and the second rotation directions R2 and R2′ are respectively perpendicular to the third rotation directions R3 and R3′.

Refer to FIG. 4B together. FIG. 4B is a schematic partial diagram of an appearance of an electronic device 100 in a folded state P1. In some embodiments, one end of the multimedia element 353 may be connected to the first fixing plate 331, the second fixing plate 332, and one rotation shaft (not shown in the figure). When the user rotates the second body 2, the rotation shaft drives the third transmission member 354′ of the multimedia element 353 and the third housing 352 to rotate synchronously, and the third transmission member 354′ drives the second transmission member 344′ and links the first transmission member 324′. Such configuration may also achieve effects of the foregoing embodiments. In other words, when the electronic device 100 is in the unfolded state P2, the sound emission holes 3521 of the multimedia element 353 may face the user, and when the electronic device 100 is in the folded state P1, the sound emission holes may be away from the first body 1 and the second body 2 and exposed to an external space.

FIG. 7C is a schematic partial side view of an electronic device 100 unfolded about 130 degrees from a perspective of FIG. 7A. In some embodiments, when the user folds the second body 2 of the electronic device 100 relative to the first body 1, the sound emission portion 3531 of the multimedia element 353 is away from the surface 1a of the first body 1 and faces an external space of the first body 1, and a sound source of the sound emission portion 3531 emits sound toward the external space of the first body 1. In addition, the sound emission portion 3531 has a sound emission direction S, where there is a first angle A1 between the sound emission direction S and the surface 1a (a second axis Y) of the first body 1, and the first angle A1 is in a range of 150 degrees to 240 degrees.

Referring to FIG. 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 element 353 rotates in the second rotation direction R2 and enables the sound emission portion 3531 to face a surface 2a of the second body 2, and the sound source of the sound emission portion 3531 may rebound to the user through the first body 1 and the surface 2a of the second body 2. In this case, there is a second angle A2 between the sound emission direction S of the sound emission portion 3531 and the surface 1a (the second axis Y) of the first body 1, and the second angle A2 is in a range of 100 degrees to 190 degrees.

Referring to FIG. 7C, in some embodiments, when the included angle α is about 130 degrees, there is a third angle A3 between the sound emission direction S of the sound emission portion 3531 and the surface 1a (the second axis Y) of the first body 1, and the third angle A3 is in a range of 15 degrees to 105 degrees, for example, 45 degrees or 55 degrees, so that the sound emission portion 3531 is close to the surface 1a of the first body 1 and faces the user. In other words, the sound source of the sound emission portion 3531 emits sound toward the user.

In this way, when the electronic device 100 is in the unfolded state P2, the sound emission portion 3531 of the multimedia element 353 can face the user; or when the electronic device is in the folded state P1, the sound emission portion 3531 of the multimedia element 353 can face the outside of the electronic device 100, to effectively release the sound source, and provide good listening experience.
