Abstract: An exemplary embodiment of the present disclosure provides a sensing device for measuring electroencephalogram (EEG). The sensing device includes an arm, a sensing portion, a multi-directional joint, a connecting base and a headband component. The arm has a front end and a back end opposite to the front end. The back end is coupled to the connecting base. The multi-directional joint is disposed on the front end, and coupled to the sensing portion, so that the sensing portion can rotate relative to the front end of the arm. The headband component includes a plurality of elastic arcuate bands and an anti-slip pad. Each of the elastic arcuate bands has a first side and a second side opposite to the first side. The first side is coupled to the anti-slip pad, and the second side is coupled to the connecting base.

Abstract: An earphone includes a body with a surrounding side, a rotatable loop and an ear hook. The rotatable loop is pivotally connected with the body on two opposite ends of the surrounding side. The body and the rotatable loop can rotate with respect to a first axis and with respect to each other. The ear hook is pivotally mounted on one side of the rotatable loop near where the rotatable loop is connected with the body, and the ear hook can rotate with respect to a second axis, which is different from the first axis.

Abstract: A Bluetooth headset includes a case, a circuit board, a speaker, a USB plug, a memory slot, an actuating structure, and a movable lid. The case is a hollow structure. A containing space in the case is accessible to an opening of the case. The circuit board is installed in the containing space. The speaker is installed on the case and electrically connected to the circuit board. Both the USB plug and the memory slot are electrically connected to the circuit board. The actuating structure is disposed on the case for driving the circuit board to selectively move the USB plug and the memory slot toward or away from the opening of the case. The movable lid is disposed at a side of the opening of the case in a rotatable manner.

Abstract: A personal audio listening device is adapted to be worn on a user's ear, and includes a housing, a pivotal knob, and an ear hook member. The housing has a surface and a hollow portion, and defines a first axis and a second axis. The pivotal knob is pivotally mounted on the surface of the housing, and includes a pair of parallel resilient walls. The ear hook member includes a hook body and an end portion. The end portion includes a pivot element in the form of a polygonal post. The hook body is configured to be wearable on the user's ear. The ear hook member is fittingly received between the resilient walls by means of the pivot element so as to be mounted on the pivotal knob. The ear hook member is pivotable about the first axis, and is rotatable about the second axis.

Abstract: An earphone includes a body with a surrounding side, a rotatable loop and an ear hook. The rotatable loop is pivotally connected with the body on two opposite ends of the surrounding side. The body and the rotatable loop can rotate around a first axis and with respect to each other. The ear hook is pivotally mounted on one side of the rotatable loop near where the rotatable loop is connected with the body, and the ear hook can rotate around a second axis, which is different from the first axis.

Abstract: A presentation apparatus includes a power management module, a storage unit, an amplifier amplifying an audio signal based on an audio control signal, a socket receiving the amplified audio signal from the amplifier, a detection circuit, a plurality of buttons, a wireless receiver/transmitter and a processing chip which connects with the power management module, the storage unit, the amplifier, the detection circuit, the buttons, the wireless receiver/transmitter to control the movement of a cursor, receive/transmit an audio signal, output the audio control signal, and determine the type of plug plugged into the socket according to the detection circuit connecting with the socket.
