Abstract
A hearing aid and a receiver for use therein, the receiver being tip-mountable in a chamber of a housing. The back chamber of the receiver is acoustically connected to the chamber of the housing. The receiver is a dual-diaphragm receiver providing no or very little vibrations, whereby the receiver is fixedly but removably mounted to the housing. Electrical connections are provided between the receiver and housing using solderless, biasing electrical contacts, whereby removal of the receiver is facilitated.
Claims11
A hearing aid or ear monitor comprising a housing and a miniature loudspeaker, wherein:
- the housing has a first compartment and a sound outlet port toward the surroundings of the housing,
- the miniature loudspeaker is removably receivable in the first compartment so that the sound outlet port is at least substantially sealed around a predetermined portion of the miniature loudspeaker,
- the miniature loudspeaker comprises a sound outlet acoustically coupled to the sound outlet port, and
- the first compartment and the miniature loudspeaker comprise mating first and second electrically conducting contact means adapted to provide solderless/solderfree, electrical conduction between the contact means of the first compartment and the miniature loudspeaker,
- wherein the sound outlet port has a predetermined inner contour in a predetermined plane, and the miniature loudspeaker has an outer contour, in a plane perpendicular to an axis of the miniature loudspeaker through the miniature loudspeaker and the sound outlet thereof, and over a majority of its length from a position farthest from the outlet and toward the outlet, which outer contour may be circumscribed by the inner contour of the sound outlet port, and
- wherein the miniature loudspeaker comprises a pair of diaphragms, the first sides of which are oppositely directed.
A hearing aid or ear monitor comprising a housing and a miniature loudspeaker, wherein:
- the housing has a first compartment and a sound outlet port toward the surroundings of the housing,
- the miniature loudspeaker is removably receivable in the first compartment so that the sound outlet port is at least substantially sealed around a predetermined portion of the miniature loudspeaker,
- the miniature loudspeaker comprises a sound outlet acoustically coupled to the sound outlet port, and
- the first compartment and the miniature loudspeaker comprise mating first and second electrically conducting contact means adapted to provide solderless/solderfree, electrical conduction between the contact means of the first compartment and the miniature loudspeaker,
- wherein the sound outlet port has a predetermined inner contour in a predetermined plane, and the miniature loudspeaker has an outer contour, in a plane perpendicular to an axis of the miniature loudspeaker through the miniature loudspeaker and the sound outlet thereof, and over a majority of its length from a position farthest from the outlet and toward the outlet, which outer contour may be circumscribed by the inner contour of the sound outlet port, and
- wherein the housing and the miniature loudspeaker comprise mating detachable fixing means adapted to position the miniature loudspeaker in a predetermined position in the first compartment, the mating detachable fixing means being operable by engaging the housing and/or miniature loudspeaker from outside the housing and/or miniature loudspeaker.
