Abstract: An electronic device including a first body having a first recess, a second body having a second recess corresponding to the first recess, and at least one dual-shaft hinge module connected to the first and the second bodies and disposed at inner sides of the first and the second bodies. The first and the second bodies rotate relatively via the dual-shaft binge module to be opened or closed. The dual-shaft hinge module has a dual protrusion structure movably accommodated in the first and the second recesses, and the dual protrusion structure moves into or out of the first and the second recesses when the first and the second bodies rotate relatively via the dual-shaft hinge module.

Abstract: A communication device includes a first body, a second body, a first audio module, and a second audio module. The second body is rotatably connected to the first body. The first audio module is disposed on the first body. The second audio module is at least partially disposed on the first body. When the second body rotates relatively to the first body to be in a first state to switch the communication device to be in a first operation mode, at least a portion of the first audio module is turned on, and the second audio module is turned off. When the second body rotates relatively to the first body to be in a second state to switch the communication device to be in a second operation mode, the first audio module is turned off, and the second audio module is turned on.

Abstract: A handle structure including a base portion, a stop portion and a grip portion is provided. The grip portion is connected between the base portion and the stop portion. The handle structure has a cavity therein, the cavity has a bottom surface, and the bottom surface of the cavity is inclined to an axial direction of the grip portion.

Abstract: The disclosure discloses an electronic device, which comprises a case and at least one display module. The case comprises a base, a housing, two connection ports and a track. The housing is disposed above the base and has an opening. The two connection ports are disposed in the housing and corresponding to the opening. The track is disposed on the edge of the base, and at least one end of the track is adjacent to the opening. At least one display module is disposed on the case and electrically connected to a corresponding one of the two connection ports and is adapted to slide on the track to generate a displacement in relative to the case. The disclosure also discloses a case which is adapted to be connected to at least one display module in the electronic device.

Abstract: A hinge structure includes a fixing component and a pivoting base. The fixing component includes a fixing base and at least three torsion hooks. The fixing base includes a first sidewall and a second sidewall opposite to each other. The at least three torsion hooks are disposed side by side between the first sidewall and the second sidewall. Each of the torsion hooks includes a fixing end portion and a pressing end portion opposite to each other. The fixing end portion of the torsion hook at center is fixed to the first sidewall, and the pressing end portion is close to the second sidewall. The two fixing end portions of the two torsion hooks at two sides are respectively fixed to the second sidewall, and the two pressing end portions are respectively close to the first sidewall. A pivoting base is rotatably disposed at the torsion hook, and the three pressing end portions respectively press the pivoting base. An electronic device having a hinge structure is further provided.

Abstract: A handle structure including a base portion, a stop portion and a grip potion is provided. The grip portion is connected between the base portion and the stop portion. The handle structure has a cavity therein, the cavity has a bottom surface, and the bottom surface of the cavity is inclined to an axial direction of the grip potion.
