Acoustic device with means for being secured in a human ear
First Claim
1. An acoustic device for being arranged in a human ear and comprising a housing configured for being located in the outer ear, and forming a closed-ear configuration in the cavum conchae, with a face adapted for abutment on the tragus, a face adapted for abutment on the antitragus, a mouthpiece adapted for being inserted into the mouthing of the auditory tract and a resilient means adapted for abutment on the cartilage arch between the antihelix and the concha and configured for influencing the housing with a force oriented generally forwards towards the tragus, wherein the resilient means comprises an elongated element that distributes the force along the cartilage arch at the concha, and that is mounted approximately tangentially relative to that face of the housing that is configured for contact with the antitragus;
- wherein the elongated element is a spring that has a spring rigidity that decreases with the distance from the housing, whereby a uniform distribution of the force towards the cartilage arch is provided at the concha.

Abstract
A device with acoustic effect and a housing for being located in the cavum conchae of a human ear. The housing has a face adapted for abutment on the tragus, a face adapted for abutment on the antitragus, a mouthpiece adapted for being inserted into the mouthing of the auditory tract. A resilient means is adapted to abutment on the cartilage arch between the antihelix and the concha and influences the housing by a force oriented forwards towards the tragus. The resilient means is a leaf spring with a spring rigidity that decreases with the distance from the housing, whereby a uniform distribution of the force towards the cartilage arch at the concha is provided. The device may be a passive noise shield or it may have on eor two transducers for one-way or two way communication.
