Audio output device for obtaining biometric data and method of operating same

An audio output device to be worn in an ear of a user, the audio output device comprising:

• a buffering member comprising a biometric sensor including a light emitter and a light receiver disposed adjacent to the light emitter and a first terminal connected to the biometric sensor;
• a housing comprising a portion to which the buffering member is mounted;
• a second terminal disposed in the portion of the housing and electrically connected to the first terminal of the buffering member;
• and
• a control circuit positioned inside the housing and operatively connected to the biometric sensor, the first terminal, and the second terminal,
• wherein the control circuit is configured to:
• supply power to the biometric sensor through the second terminal if the first terminal and the second terminal are connected, and
• receive at least one piece of biometric signal data obtained from the biometric sensor of the buffering member through the second terminal,
• wherein the buffering member comprises:
• a connection portion formed to be connected to the portion of the housing, and
• a cover formed to extend from the connection portion so as to surround the connection portion,
• wherein one region of the portion of the housing is formed to protrude and to be inserted into the connection portion of the buffering member
• wherein the first terminal is disposed in a portion of the connection portion of the buffering member,
• wherein the biometric sensor is implemented of a plurality and is disposed in circular shape inside the cover of the buffering member,
• wherein the one region of the portion of the housing comprises an embossed protrusion,
• wherein a portion of the connection portion of the buffering member comprises a recessed groove formed to correspond to the embossed protrusion, and
• wherein the housing and the buffering member are coupled in one direction,
• wherein the first terminal comprises a 1-1st terminal and a 1-2nd terminal,
• wherein the second terminal comprises a 2-1st terminal corresponding to the 1-1st terminal and a 2-2nd terminal corresponding to the 1-2nd terminal, and
• wherein if the housing and the buffering member are coupled in the one direction, the 1-1st terminal and the 2-1st terminal come into contact with each other, and the 1-2nd terminal and the 2-2nd terminal come into contact with each other.
