Definitions

  • the invention relates to a hearing aid for the hearing impaired, in particular to behind-the-ear device, with a hearing device parts, such as a microphone, amplifier, earpiece, battery, etc., housing, the parts of which are held together by releasable connecting elements, such as screws, and with an audio input connector.
  • a hearing device parts such as a microphone, amplifier, earpiece, battery, etc., housing, the parts of which are held together by releasable connecting elements, such as screws, and with an audio input connector.
  • the audio input is an electrical contact device, via which a sound-frequency electrical signal can be directly - galvanically - fed into the hearing aid amplifier.
  • the audio input is often used in schools for the hearing impaired in connection with a "frequent hearing facility" or with FM or infrared transmission systems and the like. But also in the private area the hearing impaired can be used by many additional devices such as hand microphones, TV Adapters, portable cassette players, etc., which can be connected to the audio input, benefit.
  • the audio input is a contact device that enables the connection of the output cable of an external signal source either via a pin / socket combination or via a pressure contact.
  • the so-called "audio shoe” was proposed as a way out of this situation. It is a cup-like structure that clamps or snaps around the lower part of the hearing aid. On the inside, the audio shoe has contact springs which are in line with the individual contact devices of the hearing aid in question, and on the outside there is a socket for two or three sockets has a standard Euro audio plug.
  • Such an audio shoe is described for example in DE-PS 27 51 755. However, a special manufacturer-specific audio shoe is required for each hearing aid type.
  • the object of the invention is to provide a hearing aid of the type mentioned at the outset which eliminates the disadvantages described.
  • the audio input connection takes place via at least two of the connecting elements holding the detachable housing parts together.
  • the invention thus proposes to use at least two of the connecting elements that are present anyway, such as screws, by means of which the two halves of the device housing are held together, as a contact device for the audio input.
  • This solution has the advantage that no special housing and no additional space for the contact device is required. Furthermore, when the audio shoe is removed, no components that increase the dimensions of the device are required.
  • Fig. 1 shows schematically a BTE device housing, which as usual consists of two shell halves (1, 2) and is held together by the screws (3, 4, 5), of which the screws (3, 4) as connections for the audio - Entrance can be used.
  • FIG. 2 shows in detail a sectional view of the inner construction of the housing in the area of one of the connecting elements 3 or 4.
  • a metallic stud 6 with an internal thread is injected into the lower shell 2.
  • a screw 3, which holds the upper shell 1, is screwed into this.
  • the stud 6 can be molded with the lower shell 2 and in this case is made of plastic.
  • the screw 3 In order to be able to use the screw 3 as a contact for an attached audio shoe, it is necessary to electrically connect the stud 6 to the circuit of the hearing aid. This is done with the aid of a compression spring 8, which in turn is attached to the amplifier board 7 by riveting or soldering. If there is no space for this, you can contact the stud 6 - or in the event that this is made of plastic, the screw 3 itself - with the help of a hairpin-like fork spring.
  • a connecting wire 10 can be soldered to the fork spring 9. Direct soldering to the stud is generally not advisable, since there is a risk of the housing being damaged by the soldering heat. You can also weld the connecting wire 10 - as a non-releasable connection - to the bolt 6.
  • Fig. 4 shows in section a part of the housing in the area of the connecting element with an attached audio shoe 11.
  • the shoe 11 contains resilient sleeves 12 for the euro audio connector, which make a connection to the housing screws via attached contact springs 13.
  • the head of the screw serving as contact is conical and the end of the contact spring 14 has the shape of a spherical cap. These two parts then form a clean, self-cleaning contact when the audio shoe is placed on the hearing aid.
  • the housing is therefore not damaged by the contact springs. It is also advantageous to at least lower the screw heads serving as contacts so far in the housing 1 that they cannot make contact with the skin of the hearing device wearer in the use position of the device in order to avoid undesired electrical effects or interference if no audio shoe is fitted is.
  • the resulting recesses in the housing can serve in cooperation with the spherical end of the contact springs 14 as a locking device for the entire audio shoe 11.
