Abstract
A hearing aid may include a housing shaped to rest behind an ear of a user, electric circuitry, a microphone, an antenna which receives wireless signals, a signal processor, a receiver, and a sound guide configured to sound from the receiver towards the ear. An enclosure may be provided for sound isolation of the receiver and includes a detachable lid providing access to the enclosure. A suspension body may be attached to a first suspension area and a second suspension area of the lid. The suspension body holds the receiver suspended within the enclosure. The suspension body includes suspension members connected to the suspension areas of the lid. The suspension members include protrusions that form a shelf that holds a metal shield plate between the lid and the receiver and spaced away from the receiver.
