More particularly, the disclosure relates to an in the ear type hearing aid, which comprises a housing configured to be inserted into the ear canal of a user, and which comprises at least a receiver and at least one microphone which protrudes from the housing.
  • In-the-ear type hearing aids which should be dimensioned to match a plurality of different sized ear canals, it is important that the hearing aid housing is made as compact as possibility in order to allow a greater fit rate in the ear canal. It is generally known that the size of the ear canals differs in the human population, why some hearing aids are custom designed to provide a perfectly matched hearing aid.
  • a hearing aid comprises a housing configured to be inserted into an ear canal of a hearing aid user.
  • the housing accommodates at least one microphone, a receiver, a battery, and electrical components configured to create electrical connections between the at least one microphone, the battery and the receiver.
  • the housing is configured as a casing having an outer surface.
  • the outer surface comprises at least a first opening and a second opening.

  • the second opening is configured to have arranged therein the receiver.
  • the receiver and the first microphone is arranged in said second and first opening, respectively, so that at least a surface of said receiver and said first microphone protrudes from said outer surface of the casing.
  • the outer surface of the casing may comprise a third opening, said third opening is configured to receive a second microphone, wherein a surface of the second microphone is exposed to the surroundings or protrudes from the outer surface of the casing. This allows improving the configuration of said hearing aid even for a dual microphone type in ear hearing aid.
  • the casing defines a longitudinal direction, wherein a first end faces towards the eardrum and a second end faces towards the ear canal opening when the hearing aid is inserted into an ear canal, wherein the first end may comprise the receiver, which in one end of the receiver may face towards a first surface of the battery, and the first microphone may be arranged in the second end and may face another surface of the battery.
  • the second microphone may be arranged in the first end of the casing, and substantially faces a first longitudinal side of the receiver. This further improves the configuration of said hearing aid for single as well as dual microphone type in ear hearing aids.
  • a first electrical component of said electrical components may be arranged between the second microphone and the receiver. This allows creating a physical separation between the receiver and the inner microphone, thereby lowering the risk of vibratory feedback between receiver and microphone while allowing efficient use of physical space.
  • the second end may comprise a battery drawer configured to receive a battery
  • the battery drawer is hingedly connected to the casing on a side of the battery drawer facing an end of the receiver. This allows simple replacement of the battery while efficiently using the available space.
