ABSTRACT:
An ear module with an interior lobe (200) housing a speaker (58) and adapted to fit within the Concha (103) of the outer ear, and an exterior lobe (300) housing data processing resources, includes a compressive member (202) coupled to the interior lobe (200) and providing a holding force between the anti-helix (101) and the forward wall (108) of the ear canal (102) near the tragus (104). The interior lobe (200) extends into the exterior opening (110) of the ear canal (102), and includes a forward surface (210) adapted to fit against the forward wall (108) of the ear canal (102), and a rear surface (211) facing the anti-helix (101). The width of the extension (201) (in a dimension orthogonal to the forward surface (210) of the extension (201)) between the forward surface (210) and the rear surface (211) from at least the opening of the ear canal (102) to the tip (203) of the extension (201) is substantially less than the width of the ear canal (102), leaving an open air passage (250).
