Abstract
A hearing aid comprises 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 comprises ventilation means for the purpose of increasing the lifespan of the battery.
Claims16
Hearing aid to be wearable substantially completely in an auditory canal of a user, comprising:
- a device housing which comprises a microphone at a proximal side thereof;
- a loudspeaker which is in open communication with a sound-emitting opening at a distal side via at least one sound transmission channel;
- a battery chamber for receiving a battery therein;
- and
- a sound processing device for processing a sound signal received by said microphone and sending the sound signal to said loudspeaker in an at least partly processed form,
- wherein said at least one transmission channel and said microphone being acoustically at least substantially completely separated from one another within said device,
- said device housing is releaseably accommodated in a fitting body having a close fit at least locally in the auditory canal of the user,
- said at least one transmission channel extends at least partly in a groove formed in either or both of an inner wall of said fitting body and an outer wall of said device housing, and
- said fitting body comprises said sound-emitting opening.
Hearing aid to be wearable substantially completely in an auditory canal of a user, comprising:
- a device housing which comprises a microphone at a proximal side thereof;
- a loudspeaker which is in open communication with a sound-emitting opening at a distal side via at least one sound transmission channel;
- a battery chamber for receiving a battery therein;
- and
- a sound processing device for processing a sound signal received by said microphone and sending the sound signal to said loudspeaker in an at least partly processed form,
- wherein said at least one transmission channel and said microphone being acoustically separated from one another within said device,
- said at least one transmission channel and said battery chamber being acoustically isolated from one another,
- said transmission channel between said loudspeaker and said sound-emitting opening comprises locally additional buffer space for collecting cerumen, and
- said device housing is releaseably accommodated in a fitting body having a close fit at least locally in the auditory canal of the user, and said at least one transmission channel extends between an inner wall of said fitting body and an outer wall of said device housing.
