A hearing aid which has a casing accommodating one or more second to electric signal converting transducers (11,12) and a signal path from the transducer (11,12) to a receiver which provides a sound signal at the ear of the user. The signal processing is provided in the signal path to ensure a signal amplification/attenuation according to the needs of the user. A battery (6) is accommodated in the casing and a battery lid is arranged with a first side (1) facing the surrounding and a second side (2) facing the interior of the casing whereby the battery lid is operable for replacement of the battery. The battery lid has a recess (3) for receiving at least one sound to electric signal converting transducer (11,12) and a sound transmission path is provided between the first side (1) of the battery lid and the at least one transducer (11, 12).
Method of producing a hearing aid comprising a casing and at least one transducer (11, 12) and a signal path from the transducer (11, 12) to a receiver which provides a sound signal at the ear of the user, wherein signal processing is provided in the signal path to ensure a signal amplification/attenuation according to the needs of a user, whereby the at least one transducer (11, 12) is embedded within the material of a casing part during the production thereof whereby a sound transmission path is provided between an exterior surface (1) of the casing part and the at least one transducer (11, 12), whereby the at least one transducer is mounted to a printed circuit board and where the printed circuit board and transducer assembly is embedded in the casing material during the production of the casing, such that at least an edge part of the printed circuit board is connectable from the inside of the casing.
Hearing aid comprising a casing accommodating one or more sound to electric signal converting transducers (11, 12) and a signal path from the transducer (11, 12) to a receiver which provides a sound signal at an ear of a user, wherein signal processing is provided in the signal path to ensure a signal amplification/attenuation according to the needs of the user, wherein the casing includes a faceplate, wherein a battery (6) is accommodated in the casing and wherein a battery lid is arranged with a first side (1) facing the surrounding and a second side (2) facing the interior of the casing whereby the battery lid is operable for replacement of the battery, whereby the battery lid has recess means (3) for receiving at least one sound to electric signal converting transducer (11, 12) and whereby a sound transmission path is provided between the first side (1) of the battery lid and the at least one transducer (11, 12).
