Abstract: A sound output control device includes: an orientation detecting unit configured to detect a state of orientation of a face of a user; an ambient sound obtaining unit configured to obtain ambient sound; an ambient sound reducing processing unit configured to perform, based on the ambient sound, processing of reducing the ambient sound; and a sound output control unit configured to cause sound to be output with the ambient sound reduced by the ambient sound reducing processing unit, when the detected orientation of the face of the user is in a first state, and make audibility of the ambient sound higher than in a state where the ambient sound has been reduced by the ambient sound reducing processing unit, when the detected orientation of the face of the user is in a second state changed from the first state.

Abstract: To provide an electronic device having an antenna function without having to enlarge the size of the device. The electronic device includes a shielding case, a feeding loop, an operation knob, and an antenna element. The shielding case blocks passage of electromagnetic waves. The feeding loop is a conductor that is disposed annularly along a prescribed plane outside the shielding case and is connected to a radio communication circuit encompassed within the shielding case. The operation knob is configured to be rotatable around a specific axis that passes through an annular ring formed by the feeding loop. The antenna element is an open-loop conductor fixed to the operation knob.
