Abstract
The invention relates to an audio system () for disposing in the external region of an ear, having a carrier element () for affixing to the head of the user and comprising at least one hollow space () having a primary opening () oriented in the direction of an ear opening () of the intended ear when the carrier element () is disposed as intended, and having at least one speaker () disposed in the hollow space (), the cavity () thereof being at least partially formed by a first hollow space region () and by means of which first sound waves () can be emitted through the primary opening () in the direction of the ear spaced apart from said opening. According to the invention, the hollow space () comprises a secondary opening () disposed in the first hollow space region () such that said opening is oriented away from the ear toward the surrounding area when the carrier element () is disposed as intended so that second sound waves () can be emitted through the secondary opening () by means of the speaker (), said waves being offset in phase from the first sound waves () such that the volume of the sound waves emitted by the audio system () into the surrounding area can be reduced.
