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 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.
