Claim Text:
1. A headset device measuring a biosignal, the headset device comprising: a headset body including a generally arch-shaped head holder having one or more speakers installed at each end of the head holder; a connection unit configured to move relative to the headset body; and a sensor unit mounted to the connection unit to make contact with a surface of a human body, wherein: the connection unit includes a spring which longitudinal axis is substantially perpendicular to the surface of the human body, each end of the spring being supported by the headset body and the sensor unit respectively, deformation of the spring allows the headset body and the sensor unit to move relative to each other in a transverse direction, the connection unit is spaced apart from the sensor unit, the connection unit further includes a guide bar passing through the spring and connected to an end of the sensor unit, thereby inducing deformation of the spring, the connection unit includes a hole passing through an end of the guide bar, thereby preventing the sensor unit from separating from the connection unit the sensor unit includes a light emitting element and a light receiving element configured to sense a biosignal, the biosignal is measured by comparing features of light sensed by the light receiving element via a portion of the human body exposed to light generated by the light emitting element, and the light emitting element and the light receiving element are oriented in a same direction to measure a reflected light from the portion of the human body.
