A METHOD FOR PROVISION OF A SOUND TUBE WITH A PRE-FORMED SHAPE

摘要

The present invention relates to a simplified manufacturing method for provision of a sound tube with a pre-formed shape, especially a sound tube for use in a BTE (Behind­The-Ear) hearing aid utilizing a holder with an external surface for imparting the shape of the surface to the sound tube, a first attachment element that is adapted to receive and hold a first connector at a first end of the sound tube, and a second attachment element that is adapted to receive and hold a second connector at a second end of the sound tube thereby keeping the sound tube in abutting contact with at least parts of the external surface whereby the external surface imparts the shape of the surface to the sound tube.
