Abstract: According to various embodiments, an electronic device may comprise: a front cover; a rear cover disposed opposite to the front cover; an annular portion including a side portion surrounding at least a part of the space between the front cover and the rear cover, and including a display at least partially disposed along the front cover and at least one magnetic member, comprising a magnetic material, arranged at a specified first angle and a specified first distance with respect to the center of the display; a first Hall sensor disposed at a specified second distance from the center of the display; a second Hall sensor disposed at the specified second distance from the center of the display and spaced a second angle smaller than the first angle apart from the first Hall sensor; a memory; and at least one processor, comprising processing circuitry, operatively connected to the memory.

Abstract: An audio output device is provided. The audio output device includes a housing, an audio output unit outputting audio data, a first contact sensor configured to detect a contact of an external object, a second contact sensor configured to detect a contact of the external object, a proximity sensor configured to detect a proximity of the external object within a predetermined distance, and a processor operatively connected to the audio output unit, the first contact sensor, the second contact sensor, and the proximity sensor. The processor may be configured to execute a wearing detection mode of the audio output device, to determine the contact of the external object through the first contact sensor, to determine the contact of the external object through the second contact sensor, to determine the proximity of the external object through the proximity sensor, and to determine that the audio output device is in a state worn by the external object.
