摘要： An acoustic coupler adapted for use with an intracanal receiver module can be deeply inserted into the ear canal of the user while making minimal contact with the walls of the ear canal. The minimal contact feature of the invention allows the acoustic coupler to seal the ear canal acoustically and anchor a hearing device at an optimal depth within the ear canal, while maximizing the user's comfort. The acoustic coupler is manufactured from a soft, pliable elastomer that allows it to conform readily to the shape of the ear canal. The acoustic coupler incorporates structural supports that allow the coupler to maintain an acoustical seal and withstand the inward pressure of the ear canal wall while making minimal contact with the ear canal. The invention incorporates a cerumen-protecting feature that prevents damage to a hearing device from infiltration of earwax into the sound port of the receiver. A vent pathway for control of occlusion effects is also provided. A user-friendly, attachment mechanism incorporating a snap-on, twist-off feature allows the acoustic coupler to concentrically surround the receiver module within the ear canal in a space-efficient manner.
