RF shielding structure for extended reality glasses

A method of assembling a head-worn device, comprising:

• inserting a projector into a metal support arm such that the metal support arm forms at least two faces of an electrically grounded enclosure for the projector configured to provide radio frequency (RF) shielding for the projector;
• structurally attaching the metal support arm to an optical element holder of the head-worn device;
• and
• structurally attaching the metal support arm to a rear structural element of the head-worn device,
• such that the metal support arm forms a structural support joining the optical element holder to the rear structural element without placing mechanical load on the projector.

A head-worn device, comprising:

• an optical element comprising an input optical element;
• an optical element holder configured to hold the optical element;
• a projector;
• a rear structural element;
• and
• a support arm assembly, comprising an electrically grounded enclosure for a projector configured to provide radio frequency (RF) shielding for the projector, the support arm assembly comprising:
• a metal support arm:
• configured to form at least two faces of the enclosure;
• configured to structurally attach to the optical element holder;
• and
• configured to structurally attach to the rear structural element;
• such that the metal support arm forms a structural support joining the optical element holder to the rear structural element without placing mechanical load on the projector.
