Head mounted electronic device

A head mounted electronic device comprising a headphone and a display portion wherein the headphone further comprises:

• a C-shaped elastic belt having two coupling ends;
• two movable members, each movable member having a first end and a second end and being rotatably coupled to a corresponding coupling end of the elastic belt via the first end of the movable member, the movable member being configured to rotate with respect to the corresponding coupling end of the elastic belt along a first axis, and
• two speakers, each speaker including a periphery and a body and being rotatably coupled to the second end of a corresponding movable member via the periphery of the speaker, the speaker being configured to rotate with respect to the corresponding movable member around a second axis across both the periphery and the body of the speaker, wherein the second axis and the first axis define a first angle therebetween;
• and
• the display portion further comprises:
• a main body, configured to produce and project images outwardly;
• and
• two coupling components, coupled to two opposite ends of the main body and each being rotatably coupled to a corresponding speaker around a respective third axis, wherein the two third axes define a second angle therebetween;
• wherein a folding of the display portion towards a position substantially overlapping with the elastic belt causes each of the two speakers and a corresponding movable member to which the speaker is coupled to rotate with respect to a corresponding coupling end of the elastic belt along a corresponding first axis, thereby avoiding twisting between the elastic belt and the two movable members.
