Abstract: An electronic device includes a body and a first support coupled to one portion of the body, where the first support extends from the body along a line in a first direction relative to a central axis of the body. The device further includes a second support coupled another portion of the body, where the second support extends from the body along a line in a second direction relative to a central axis of the body, and an ear loop connecting the first support to the second support. The shape of the ear loop permits coupling with a user's ear, such that the shape of the ear loop changes according to changes in a degree of an angle between the line in the first direction and the line in the second direction.

Abstract: An earphone capable of making it easy to remove foreign substances that have accumulated on a nozzle portion and easy to control sound characteristics thereof is provided. The earphone includes a driver, a housing defining an electrical component mount on which the driver is mounted, a nozzle portion provided at one end of the housing and defining therein a nozzle hole communicating with the electrical component mount, a nozzle cap detachably coupled to an outer circumferential surface of the nozzle portion, and a nozzle mesh provided at the nozzle cap so as to cover the nozzle hole, wherein the nozzle cap serves to decrease output in a second peak region in a graph of output over frequency for the earphone and to increase a fourth peak region or expand a bandwidth of the fourth peak region in the graph.

Abstract: An ear unit and a portable sound device having the same are provided. The ear unit includes a driver unit, an ear housing configured to form an electric part in which the driver unit is mounted and including a bass hole and a flat hole formed in a first surface of the electric part, a rotator including a second surface opposite the first surface and rotatably coupled to the ear housing, and an opening/closing hole provided in the second surface of the rotator to open or close the bass hole or the flat hole according to rotation of the rotator. The flat hole is connected to an inner hole formed in one position inside the first surface so as to form a duct.
