Abstract:
1. A non-electronic hearing aid foldable between folded and collapsed condition and comprising a resilient sheet material substrate defined as having at least three interconnected, inter-foldable panel portions including: a first substrate panel portion having a flexible sound capturing surface with a generally parabolic outer peripheral edge, said first panel portion structurally defined by said outer peripheral edge and its intersecting first and second substantially linear panel edges; a second substrate panel portion sharing said first linear edge with said first panel portion, and having a second edge configured in a general c-shape with generally opposed terminal ends for fitting about a user's ear so as to retain said second substrate panel closely adjacent said user's head; a third substrate panel portion is separated by a slit from said second substrate panel portion but shares said second linear edge with said first panel portion and includes a second connector part configured to mate with said first connector part of said single fastener for securing said resilient sheet material substrate in a folded position; said first and second substrate panel portions, in folded condition, interconnect at said first linear edge at an included angle of between 45 and 90 degrees, while said second and third substrate portions overlap one another to form a three-dimensional sound catching shape; whereby said hearing aid in its folded condition suspends from an upper edge of the user's ear and fits in close proximity to a back portion thereof due to the included angle of said first and second substrate portions such that sound waves cannot be trapped between the flexible sound capturing surface and the back of the user's ear.
