发明名称 Hearing aid
摘要 <p>The invention relates to a Hearing aid comprising a housing shaped to rest behind the ear of a user, where the housing encloses electric circuitry which interconnects power input terminals or battery terminals, a microphone which converts a sound signal into an electric signal in the circuitry, an antenna which converts possible wireless signals into electric signals in the circuitry, a signal enhancer or amplifier which amplifies the electric signals from the microphones and/or from the antenna, a receiver unit which receives the amplified signal from the amplifier and produces sound waves, sound guiding means which are arranged to guide the sound from the receiver unit towards the ear of the user, where an enclosure is provided within the housing for sound isolation of the receiver, where access to the enclosure is granted by means of a detachable lid and were the receiver is flexibly suspended for free movement from the lid at a first suspension area and a second suspension area distanced from said first suspension are. The object of the present invention is to provide a construction which allows the insertion of a my-metal shield in a hearing aid comprising a receiver enclosure, without fundamentally changing the design of the hearing aid. The problem is solved in that a metal shield plate is provided between the receiver and the lid extending from the first to the second suspension area.</p>
