Abstract: Described herein is an in-ear device that is at least partially insertable into an ear canal of a user. The in-ear device comprises a housing that is mechanically releasably coupled to a connector by way of a dedicated opening provided in the housing. The connector is made of an elastic material, a tubular overall shape defining a longitudinal axis and radially delimits a sound channel. The connector is mechanically releasably coupled to a loudspeaker unit at a second end of the connector. A cerumen protection unit is connected to the connector by an adhesive-free and non-losable connection.

Abstract: The disclosure relates to a hearing device configured to be worn at an ear of a user, the hearing device including a sound delivery (SD) part configured to be at least partially inserted into an ear canal and having a custom shell at least partially customized to the ear canal and an electroacoustic transducer housed within the custom shell. The hearing device further includes a mechanical element connected to a medial end of the custom shell of the SD part, the mechanical element having a structure enclosing a cavity with an opening facing the SD part such that the cavity is acoustically coupled to the electroacoustic transducer. The structure includes a section in which thinner portions and thicker portions are alternatingly arranged around an axis of the structure.

Abstract: Described herein are a receiver for a hearing instrument, the receiver comprising: a case having a tubular shape with at least one open end, a flexible or partially flexible printed circuit board populated with a plurality of MEMS receiver cells, wherein the printed circuit board is folded to form a hollow body and inserted in the case with the MEMS receiver cells facing inward and/or outward, and at least one cap closing the open end of the case, wherein one of the caps comprises a sound port for guiding sound produced by the MEMS receiver cells out of the receiver.

Abstract: An illustrative cartridge includes a transparent vial, at least partially filled with a curable liquid printing material, a cap sealing the vial, and at least one solid structure submerged in the liquid printing material.

Abstract: An ear tip is described for retaining a hearing device or a hearing device part in an ear canal of a user wearing the hearing device or the hearing device part. The ear tip includes a sealing element with a sound channel providing for a sound path between a sound inlet opening for receiving an acoustic signal from an output unit of the hearing device or the hearing device part and a sound outlet opening for releasing the acoustic signal to the ear canal of the user wearing the hearing device or the hearing device part, and a first filtering element arranged in the sound channel between the sound inlet opening and the sound outlet opening.
