Abstract

The invention relates to an electrodynamic loudspeaker comprising a feed line inwardly relative to a coil former. An electrodynamic loudspeaker (5) comprising: - a base, - a magnetic circuit defining at least one gap, - an assembly movable in translation relative to the base along an axis (D) of the loudspeaker, the assembly comprising at least one a film, a coil former (37) fixed on the film and at least one coil (39) fixed on the coil former and located in the gap, and a feed system (29) configured to feed the coil, the feed The system includes at least two conductive wires (49, 51), each of which includes a first end (59) connected to a coil (39) and a second end (61) mechanically coupled to a magnetic circuit . Each of said two wires comprises at least one portion (63) located radially between the axis (D) and the coil and axially between the magnetic circuit and the membrane.

Description

【Technical field】

[0001] The invention relates to an electrodynamic loudspeaker comprising: a base; a magnetic circuit defining at least one gap; an assembly movable in translation relative to the base along an axis of the loudspeaker, the assembly comprising at least one membrane configured to emit sound waves, secured to the membrane a coil former and at least one coil fixed on the former and positioned in the gap; and a feed system configured to feed the coil, the feed system comprising at least two conductive wires, each of the conductive wires It includes a first end connected to the coil and a second end mechanically coupled to the magnetic circuit.

[0002] The invention also relates to a sound enclosure comprising such a loudspeaker. 【Background technique】

[0003] A variable current is passed through the coil to obtain axial vibrations of the membrane, which are converted into sound waves. The coil is fed externally, usually by two conductive wires radially outwar...
