Abstract: Disclosed is a headphone including a headband and two ear cups connected to opposite ends of the headband. Each of the ear cups includes a shell, a front cover, and a light sensor. The shell has an open end. The front cover covers the open end of the shell. The front cover is in a basin form and has a peripheral sidewall and a bottom wall. The light sensor is located on the peripheral sidewall of the front cover. The light sensor includes a light-emitting unit and a light detection unit. When a user wears the headphone, light emitted by the light-emitting unit irradiates a flat portion of a back surface of an ear of the user.

Abstract: Disclosed is an open ear headphone, including a housing, a speaker arranged in an accommodating space inside the housing to define the accommodating space into a front cavity and a rear cavity, a connecting member including opposite first and second ends, and a supporting member connected to the second end and including a supporting portion and a sound outlet channel. A sound outlet is provided on a surface of the housing and is in acoustic communication with the front cavity. The first end is connected to the surface of the housing. When a user wears the open ear headphone, the housing is located in a concha cavity of the user's ear, the supporting portion at least leans against a lower edge of the concha cavity, and the sound outlet channel is in acoustic communication with the user's ear canal and is not in contact with the user's ear.

Abstract: An earbud including a main body, a sound guiding structure, a battery, and a sensor is provided. A geometric shape of the main body has a long axis and a short axis orthogonal to each other. When the earbud is worn, the main body is housed in a concha cavity of a user, and a tragus of the user and the long axis are located on a same level. The sound guiding structure extends away from the main body from the long axis of the main body. The battery and the sensor are disposed in the main body, and the sensor is adjacent to a periphery of the battery.

Abstract: An electronic device includes a body, an input device and a connecting mechanism. The connecting mechanism includes a first connector and a second connector installed on the body and the input device, respectively. The connectors are connected via a magnetic interaction. When the electronic device approaches the input device, the electronic device is fixed on the input device by the magnetic interaction.

Abstract: A portable electronic device includes a base, a cover and a connecting element. The cover includes a track and a rotating portion next to the track. The connecting element is connected to the base wherein the track is movable with respect to the connecting element and is connected to the connecting element. When the connecting element is in the rotating portion, the cover is rotatable with respect to the base.

Abstract: A portable electronic device. The portable electronic device includes a base, a body, and a connecting mechanism. The body has a first surface and a second surface, wherein the first surface faces the base. The connecting mechanism rotatably connects the base and the body. The connecting mechanism rotates relative to the base to a specific angle. The body rotates relative to the connecting mechanism, allowing the second surface to face the base.

Abstract: A portable electronic device comprises a base, a cover and a linkage mechanism. The linkage mechanism comprises a first linkage assembly and a second linkage assembly. The first linkage assembly pivots to the cover. The second linkage assembly pivots to the first linkage assembly and the base, respectively. The second linkage assembly is movably installed on the base.

Abstract: An input device and a handheld electronic device comprising the input device are provided. The input device comprises an elastic sheet and a switch sheet, both with alignment through-holes for precise alignment. Thereby, a protrusion of the elastic sheet is disposed precisely above a switch of the switch sheet. Because of the inerrable assembly of the input device, the handheld electronic device will have an acute response to the depression made by the user.

Abstract: A key structure of a portable electronic device is provided. The portable electronic device has a first operation mode and a second operation mode. The key structure comprises a key, a first light source, and a second light source. The first light source emits a first colored light in the first operation mode so that the key can display a first input symbol. The second light source emits a second colored light in the first operation mode so that the key can display a second input symbol. As a result, users who operate portable electronic devices with the aforementioned key structure can easily recognize the different kinds of input symbols corresponding to different input methods in different operation modes.
