Abstract
An audio system worn near the user's ear has a carrier element and a speaker. The carrier element is configured for affixing the audio system to the head of the user and defines a hollow space having a primary opening oriented in the direction of the opening of the user's ear when worn and emitting first sound waves from the speaker. The hollow space includes a secondary opening disposed in a first hollow space region of the carrier element and oriented away from the ear toward the surrounding area when the carrier element is worn so that the speaker emits secondary sound waves through the secondary opening, and the secondary sound waves are 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.
