Loudspeaker apparatus with circumferential, funnel-like sound outlet opening

摘要

A loudspeaker apparatus has at least one sound generator wherein an at least partially sound-conducting channel is arranged in a sound radiation direction of the sound generator and is suitable for directing sound emerging from the sound generator along the course of the sound-conducting channel such that the sound emerges from the loudspeaker apparatus at a second end of the sound-conducting channel, which end is in the form of a sound outlet opening, at a radiation angle which defined by the sound outlet opening.

主权项

1. A loudspeaker apparatus which comprises at least one sound generator, wherein a channel which conducts sound at least in part is arranged in one sound radiation direction of the sound generator, which channel is suitable for directing sound emerging from the sound generator along the course of the sound-conducting channel in such a way that the sound emerges from the loudspeaker apparatus at a second end—designed in the form of a sound outlet opening—of the sound-conducting channel at a radiation angle defined by the sound outlet opening, characterized in that the sound-conducting channel has on an inner wall a mainly sound-reflecting material in some portions and a mainly sound-absorbing material in other portions, wherein the mainly sound-reflecting material is arranged inside the sound-conducting channel on a face situated radially on the inside and the mainly sound-absorbing material is arranged inside the sound-conducting channel on a face situated radially on the outside, and a cross-section of the sound-conducting channel is made substantially constant over at least 50% of the length of the sound-conducting channel.
