Wearable electronic device with an optical sensor module integrated with a wireless charging module

A wearable electronic device, comprising:

• a housing including a front surface facing a first direction, a rear surface facing a second direction opposite to the first direction, and a side surface surrounding a space between the front surface and the rear surface;
• a display disposed in the housing and visibly exposed through the front surface;
• a circuit board disposed in the housing;
• a module assembly disposed between the circuit board and the rear surface, and electrically connected with the circuit board;
• and
• a connecting member connecting the module assembly and the circuit board,
• wherein the module assembly includes:
• an optical sensor module including a flexible printed circuit board (FPCB) including a first surface facing the second direction and a second surface facing the first direction, a light emitting part disposed on the first surface of the FPCB, and a light receiving part disposed on the first surface so as to be spaced apart from the light emitting part, and
• a wireless charging module surrounding the FPCB and at least partially coupled to the FPCB so as to be integrated with the FPCB, and
• wherein the optical sensor module is configured to detect a biometric signal of an external object as the light emitting part emits light in the second direction, and the light receiving part receives emitted light reflecting off the external object, when the external object is in contact with the rear surface of the wearable electronic device;
• wherein the wireless charging module further includes a third surface facing a same direction as the first surface of the FPCB, and a fourth surface facing a same direction as the second surface of the FPCB;
• and
• wherein the FPCB is disposed between the geometric planes extending the third surface and the fourth surface when a side section of the module assembly is viewed, and the side section is a section in a direction substantially perpendicular to the third surface or the fourth surface.
