ABSTRACT:
A connector connects sound-conduction tubing from a hearing aid to sound-conduction bore in an earmold. The connector is an elbow-shaped member with one end receiving an end of the sound-conduction tubing while the other end has latching means that latchably mate with a seating member disposed in an entry section of the sound-conduction bore. The inside diameter of the sound-conduction tubing, the diameter of the sound-conduction tubular passage in the elbow-shaped member and the diameter of the sound-conduction bore are the same therealong thereby defining a continuous-flow sound-conduction path from the hearing aid to the end of a canal of the earmold. A filter can be disposed in the one end of the connector with the sound-conduction tubing engaging the filter.
