Wearable electronic device comprising damping structure of circuit board

A wearable electronic device comprising:

• a housing including a cover:
• a bracket disposed in the housing and including a first part:
• a printed circuit board disposed between the cover and the bracket and at least partially facing a first surface of the first part of the bracket:
• a sound sensor structure disposed on a second surface that is different from the first surface of the first part of the bracket:
• a biometric sensor structure installed in the cover to overlap the first surface of the first part of the bracket with respect to a direction that is perpendicular to the printed circuit board;
• and
• a damping structure interposed between the biometric sensor structure and the printed circuit board and configured to elastically support the biometric sensor structure and the printed circuit board,
• wherein the damping structure is arranged to overlap the sound sensor structure with respect to the direction that is perpendicular to the printed circuit board.
