Definitions

  • a hearing aid apparatus having an acoustic receiver member extending outwardly from the upper portion of a front face of a housing, the upper portion of the housing being angulated so that the receiver angle approximates the normal angle of the ear canal with the ear concha.
  • the lower portion of the housing front face being angulated to approximate the angle of the ear concha.
  • the receiver is mounted with respect to the housing by means of a cupshaped retainer supporting one end of the receiver 'while a hollow cap member encloses the remainder of the receiver.
  • This invention pertains to improvements in hearing" aids, and more particularly to improvements in an in-theear hearing aid which is designed to be worn in the external ear of the user.
  • the in-the-ear hearing aid disclosed in US. Patent No. 3,197,576 comprises generally a housing which includes a microphone, amplifier, and a source of energizing potential for the amplifier, preferably a battery.
  • a receiver which has an electrical input and produces an acoustic output has its electrical input connected to the output of the amplifier, and the receiver is mounted within a soft resilient boot, usually of a soft rubber material, and is flexibly attached to the hearing aid housing, the receiver normally extending outwardly from the front face of the housing at a 90 angle.
  • the end of the soft resilient boot has an aperture therethrough adjacent the acoustic output of the receiver so that the acoustic output energy of the receiver always travels in the same acoustic medium, that is, air.
  • a wax guard such as the wax guard shown in United States Patent, Kuklock, 3,197,577, is mounted in the aperture of the boot to prevent earwax from entering the receiver output.
  • the resilient boot in order to provide a covering for the receiver which is adequately strong, the resilient boot must be fairly thick so as to provide suflicient mechanical strength. It has been discovered that the thickness of the boot preventsthis hearing aid being used by certain people with hearing deficiencies, since their ear canal is too small to receive the "ice boot covered receiver. It has also been found that insertion of the hearing aid housing in the outer ear of the wearer sometimes causes an irritation or soreness due to engagement of the edge of the housing with the concha of the ear.
  • the present invention provides an in-the-ear hearing aid which, because of its novel construction, is much less susceptible to damage even when mistreated or mishandled by the wearer.
  • the present invention comprises a housing which, when the hearing aid is being used, is fitted in the external ear of the user.
  • the housing has a front face having an upper portion which extends downwardly and inwardly toward a vertical plane, and a lower portion which extends downwardly away from the vertical plane.
  • the housing also has a battery compartment door which forms a part of the front face and which is located between the upper and lower portions of the housing face.
  • An elongated receiver is flexibly mounted to the face of the housing and extends outwardly therefrom, the longitudinal axis of the receiver being generally perpendicular to the upper portion of the housing face.
  • the mounting for the receiver comprises a cup-shaped retainer which has a flexible link extending outwardly from the base of the retainer in the direction of the longitudinal axis of the retainer.
  • the receiver member has an electrical input and an acoustic output end, and the electrical input end is mounted within the cup-shaped retainer with the acoustic output end of the receiver extending out of the retainer.
  • the flexible link of the retainer is mounted or connected to the upper face of the housing.
  • An elongated hollow cap member preferably of plastic, is placed over the portion of the receiver which extends out of the cup-shaped retainer, the hollow cap thereby enclosing the exposed portion of the receiver.
  • the end of the hollow cap adjacent the acoustic output end of the receiver has a plurality of apertures therethrough to allow transfer of the acoustic energy output from the receiver to the users eardrum.
  • a generally umbrella-shaped tip is mounted in spaced relation to the end of the cap member to cover the apertures through the end of the'cap and prevent earwax from plugging the cap apertures, however, as mentioned previously, the tip is spaced from the end of the cap so as to allow transfer of acoustic energy.
  • the hollow cap which encloses the hearing aid receiver is readily removable so that the entire cap may be replaced in the event of damage. In the event the cap-apertures become plugged with earwax, the cap is readily removable for cleaning.
  • the receiver Since the elongated receiver is mounted such that its longitudinal axis is perpendicular to the an-gulated upper face of the hearing aid housing, the receiver extends outwardly from the housing at an angle.
  • the angle at which the receiver extends from the housing is chosen to closely approximate the approach angle of the human ear canal so as to facilitate insertion of the receiver into the ear canal, and also to minimize any strain on the flexible link or mounting between the retainer and the hearing aid housig.
  • the amount of angulation of the lower portion of the hearing aid face is chosen to closely approximate the angle of the concha of the ear so as to prevent or minimize engagement of the housing with the ear concha, thereby preventing any soreness of the ear which may be occasioned by the wearing of the hearing aid.
  • Another object of the present invention is to provide an in-the-ear hearing aid, wherein the hearing aid receiver is mounted at an angle closely approximating the approach angle of the human ear canal.
  • a further object of the present invention is to provide an in-the-ear hearing aid having an improved receiver mounting and cover.
