Abstract

An ear hook is to be able to be tightly attached to a hearing device housing in a simple fashion. To this end, provision is made for it to be possible to clip the ear hook onto the hearing device housing. One of the two parts; hearing device housing and ear hook has a sound outlet tube, which can be inserted into a corresponding opening in the other part. The two parts are detachably fastened to one another in an axial direction in respect of the sound outlet tube by means of a magnetic connection. The magnetic connection ensures that the two components are fitted tightly onto one another, though it enables said two components to rotate in respect of each other.

Claims

1. A behind-the-ear hearing device, comprising:

a hearing device housing;

an ear hook that is clipped onto the hearing device housing; and

a sound outlet tube arranged in the hearing device housing that is inserted into an opening in the ear hook,

wherein the hearing device housing and the ear hook are configured to be detachably attached to one another in an axial direction of the sound outlet tube by a magnetic connection.

2. The behind-the-ear hearing device as claimed in claim 1, wherein the magnetic connection is generated by a ring-shaped magnet arranged at an edge of the opening in the ear hook and a ferromagnetic section of the hearing device housing as a magnetic counterpiece.

3. The behind-the-ear hearing device as claimed in claim 1, wherein the magnetic connection is generated by a ring-shaped magnet arranged around the sound outlet tube in the hearing device housing and a ferromagnetic section of the ear hook as a magnetic counterpiece.

4. The behind-the-ear hearing device as claimed in claim 1, wherein the hearing device housing and the ear hook are rotatable about the axis of the sound outlet tube in respect of one another when attached.

5. The behind-the-ear hearing device as claimed in claim 1, wherein the hearing device housing and the ear hook are directly attached to one another.

6. The behind-the-ear hearing device as claimed in claim 1, wherein a clip is arranged on the hearing device housing and a recess is arranged on the ear hook to engage the hearing device housing to the ear hook.

7. The behind-the-ear hearing device as claimed in claim 1, wherein a clip is arranged on the ear hook and a recess is arranged on the hearing device housing to engage the hearing device housing to the ear hook.

8. A behind-the-ear hearing device, comprising:

a hearing device housing;

an ear hook that is clipped onto the hearing device housing; and

a sound outlet tube arranged in the ear hook that is inserted into an opening in the hearing device housing,

wherein the hearing device housing and the ear hook are configured to be detachably attached to one another in an axial direction in respect of the sound outlet tube by a magnetic connection.
