Abstract: A hearing instrument includes a housing and at least one electroacoustic input transducer adapted to generate a corresponding electrical input signal from an ambient sound. The housing has a sound entry opening. A sound channel, which guides a sound path from the sound entry opening to the input transducer, is formed inside the housing. A contamination filter, which is transmissive for sound, at least partially covers a first cross section of the sound channel. The sound channel forms a sound chamber between the contamination filter and the sound entry opening, in such a way that the housing partially overlaps the sound chamber in the region of the sound entry opening.

Abstract: An electronic module for a hearing instrument to be worn in the ear canal has a rechargeable battery, a circuit carrier, and a chipset arranged on the circuit carrier and forming an audio processor, and power management electronics. The circuit carrier is strip-shaped and, in the intended assembly state, is wrapped, in sections and bent, around the rechargeable battery in such a way that the rechargeable battery is at least partially arranged between the audio processor and the power management electronics.

Abstract: An electronics module for a hearing instrument to be worn in the auditory canal has a rechargeable battery, a mechanical holder, in which the rechargeable battery is received in the intended assembly state of the electronics module, a circuit carrier, and a chipset arranged on the circuit carrier. The circuit carrier is band-shaped and in the intended assembly state is laid in sections and bent around the mechanical holder. There is also described a hearing instrument module and a complete hearing instrument.

Abstract: A charging device of a hearing aid has a charging unit, which has a housing with a housing cover and a magnet arranged therein and movably guided in a longitudinal direction. At one longitudinal end, a contact is attached on the magnet for the detachable, direct electrical contacting with a counter contact of the hearing aid. The contact is electrically connected by a line to a charging circuit, wherein the housing cover has an opening, within which the contact is inserted. The charging device is part of a system having a hearing aid.
