Loudspeaker comprising a magnetic circuit defining at least one conduit for fluidly connecting an air gap and a loading volume

Abstract

A loudspeaker comprising a defined magnetic circuit with at least one conduit for fluidly connecting an air gap and a loading volume. A loudspeaker (12), particularly one intended for emitting high frequencies, defining a central axis (X) and comprising: - a magnetic circuit (20) defining a housing (22), - an assembly (26) that is axially movable relative to the magnetic circuit, comprising a diaphragm (28) adapted for emitting sound waves and defining a front side of the loudspeaker, - a suspension (34) mechanically connecting the diaphragm to a chassis (36) of the loudspeaker, and - a cover (38) extending axially from the rear side relative to the magnetic circuit and delimiting a loading volume (40). The magnetic circuit defines: - a radially inner surface (44) delimiting a central passage (46) axially connecting an air volume (48) located behind the membrane and the charge volume, and - a conduit (50A) fluidically connecting, on the one hand, the housing and, on the other hand, the charge volume or the central passage.
