Embodiment Construction

[0025] refer to figure 1 The speaker 1 according to the present invention will be described.

[0026] The loudspeaker 1 is configured to be integrated in a cabin (not shown) of a motor vehicle (not shown).

[0027] The loudspeaker 1 comprises a cabinet 3 , a loudspeaker 5 and advantageously further loudspeakers 7 , 9 , 11 .

[0028] Apart from a substantially planar surface 13 surrounding the loudspeaker 11 , the enclosure 3 has an advantageously substantially spherical general shape.

[0029] The loudspeaker 7 is, for example, structurally similar to the loudspeaker 5 and is mounted upside down from the loudspeaker 5 along an axis D common to both loudspeakers.

[0030] Loudspeaker 9 is, for example, a midrange and tweeter with a passband extending advantageously between 200 Hz and 25 kHz. The loudspeaker 9 is intended, for example, to diffuse sound waves in the interior space (not shown) of a cab of a motor vehicle (not shown).

[0031] Loudspeakers 11 are also, for exam...

Abstract

Electrodynamic loudspeaker including: - a chassis; - a magnetic circuit defining at least one air gap; - an assembly that is movable with respect to the chassis in translation along an axis (D) of theloudspeaker, the assembly including at least one diaphragm configured to emit sound waves, a coil holder (37) attached to the diaphragm, and at least one coil (39) attached to the coil holder and located in the air gap; and - a power supply system (29) configured to supply electrical power to the coil, the power supply system including at least two electrically conductive wires (49, 51), each ofthe wires comprising a first end (59) that is connected to the coil (39) and a second end (61) that is mechanically rigidly connected to the magnetic circuit. Each of the two wires comprises at leastone portion (63) that is located radially between the axis (D) and the coil, and axially between the magnetic circuit and the diaphragm.

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...
