Abstract
A device having an earphone is provided to be attached to the tragus of the outer ear of a person, wherein two levers held to one another in a pivotal manner from opposite sides, driven by an elastically preloaded part, press onto the tragus. The levers both have two arms, wherein the pivot axis is at a distance from the ends of the two levers in the longitudinal direction of the lever and lies outside the normal projection towards the surface of the tragus when the device is attached as intended to the tragus, and/or the elastically preloaded part is a pre-curved bending spring which is pre-curved by more than 360°.
Claims11
An earphone device comprising:
- an inner lever and an outer lever which are arranged oriented parallel or at an acute angle to each other and are connected to each other pivotably with respect to a pivot axis, wherein
- the inner lever, when the device mounted on the tragus, is provided to bear on the tragus from the inside via a region of contact lying remote from the pivot axis, and the outer lever, with the device mounted on the tragus, is provided to bear on the tragus from the outside via a region of contact lying remote from the pivot axis, wherein
- the device is securable on an ear by means of the two levers pressing on the tragus from opposite sides, wherein
- an elastically prestressed part is in engagement with both levers in such a way that, on account of its elastic prestressing force, it causes a torque between the two levers about the common pivot axis,
- wherein, the two levers both have two arms, wherein the pivot axis lies at a distance from the ends of both levers in a respective longitudinal direction of the levers and moreover lies outside the normal projection in side view onto the surface of the tragus when the device is fitted on the tragus.
