Abstract
A hearing aid includes a microphone on a proximal side of a device housing and a loudspeaker which via a transmission channel is in open communication with a sound-emitting opening of the device. A sound processing device serves to generate sound received by the microphone to the loudspeaker in amplified form. The device housing is provided on a distal side with an optionally sealed battery chamber for receiving a battery therein. The transmission channel is at least almost wholly separated from the microphone acoustically in order to prevent acoustic feedback. The battery chamber includes ventilation elements for the purpose of increasing the lifespan of the battery.
Claims16
Hearing aid adapted to be received at least almost completely in an auditory canal of a user in at least locally fitting manner, comprising a device housing having on a proximal side a microphone and on a distal side a loudspeaker which is in open communication with a sound-emitting opening of the device via at least one transmission channel, said hearing aid further comprising a battery chamber for receiving a battery therein and a sound processing device for generating sound received by the microphone to the loudspeaker in at least partly processed manner, characterized in that the device housing is at least partly enclosed in a fitting body having an outer wall which is adapted to lie at least locally sealingly against a wall of an auditory canal of the user, in that said fitting body comprises the sound-emitting opening, in that a groove in a wall of said fitting body between the loudspeaker and the sound-emitting opening comprises at least part of said transmission channel, and in that said transmission channel comprises at least one curve between the loudspeaker and the sound-emitting opening.
