Wearable device comprising at least one electrode for measuring biometric information

A wearable device comprising:

• a housing comprising a first surface facing a first direction, a second surface facing a second direction opposite to the first direction, and a third surface at least partially surrounding a space between the first surface and the second surface;
• a printed circuit board disposed between the first surface and second surface of the housing;
• a speaker device disposed in a cavity formed by the third surface of the housing, between the first surface and second surface of the housing;
• a flexible printed circuit board disposed to surround at least a part of the speaker device and electrically connected to the printed circuit board, and comprising a first conductive connector in a first area facing the third surface of the housing;
• and
• at least one first electrode connected to the first conductive connector and electrically connected to the flexible printed circuit board,
• wherein the at least one first electrode is disposed to be at least partially exposed to the outside of the third surface of the housing through an opening formed in the third surface of the housing and is configured to be in contact with at least a portion of a body of a user of the wearable device,
• wherein the flexible printed circuit board is electrically connected to the at least one first electrode, based on the first conductive connector, and provides a first signal path between the at least one first electrode and the printed circuit board, and is electrically connected to the speaker device, based on a second conductive connector comprised in a second area, and provides a second signal path between the speaker device and the printed circuit board,
• wherein the wearable device further comprises:
• a plurality of second electrodes exposed to the outside through the second surface of the housing;
• and
• a biometric sensor module electrically connected to the at least one first electrode and the plurality of second electrodes, and
• wherein the biometric sensor module provides an electrical signal or data value corresponding to body composition information of a user, based on contact of the user's body with at least one of the at least one first electrode or the plurality of second electrodes.
