Abstract

A sound transducer, particularly an earphone, is buttoned into a sound opening of an in-the-ear hearing aid housing by means of an elastic hose part seated on a sound connector of the sound transducer. The elastic hose part is slightly pre-stressed in longitudinal direction and the sound transducer is provided with an elastic abutment that elastically compensates the prestress.

Claims

1. A mount for a sound transducer, particularly an earphone, having a sound connector in a housing of a hearing aid having a sound opening, particularly an in-the-ear hearing aid, close to the sound opening, whereby the sound transducer is buttoned into the sound opening by means of an elastic hose part seated on the sound connector and is also at least partially provided with an elastic support, comprising the improvement wherein the elastic hose part is slightly elastically stretched in longitudinal direction such that it pulls the sound transducer in the direction of the sound opening and the sound transducer is provided with the elastic support as an elastic tension abutment.

2. A mount according to claim 1, wherein the elastic hose part and the sound opening are buttoned to one another by means of a bead-channel connection.

3. A mount according to claim 2, wherein the elastic hose part embraces an annular bead that can be buttoned into an annular channel of the sound opening that mates therewith.

4. A mount according to claim 3, wherein the annular channel has a distal, annular lateral face, the channel being proximally open, and only the distal, annular lateral face thereof forms an abutment for the elastic hose part that is stretched in the longitudinal direction.

5. A mount according to claim 1, wherein the hose part at least partially projects beyond or over the sound connector of the sound transducer and has its projecting part buttoned into the sound opening.

6. A mount according to claim 1, wherein the elastic hose part is glued to the sound transducer.

7. A mount according to claim 1, wherein the sound transducer is at least partially seated in a pocket of elastic material that contacts the inside wall of the housing of the hearing aid in at least punctiform fashion and thus forms the tension abutment.

8. A mount according to claim 7, wherein the pocket approximately covers that half of the sound transducer opposite the sound connector.

9. A mount according to claim 1, wherein the sound opening likewise comprises a connector or neck form and the sound transducer is buttoned into this connector by means of the elastic hose part.
