A loudspeaker is proposed, having an enclosure where the following components are installed: a magnetic circuit, a permanent magnet, a coil, a system positioning the coil in the gap between the enclosure and a permanent magnet, a resonating membrane diffuser, attached by an attachment mechanism to the coil, and lead wires with terminals. The coil is star-shaped. The technical result is to increase the loudspeaker's power and efficiency, to reduce its weight and size, and to improve the sound quality.
1. A loudspeaker comprising:
an enclosure having installed therein:
a magnetic circuit,
a permanent magnet with a gap between the enclosure and the permanent magnet,
a coil having a plurality of turns, wherein each turn of the coil is formed into a star shape configuration having a plurality of alternating beams and cavities, and
a system configured for positioning the coil in the gap between the enclosure and the permanent magnet;
a membrane attached by an attachment mechanism to the coil; and
lead wires attached to terminals and to the coil.
2. A loudspeaker according to claim 1 , wherein each beam of the plurality of beams of the turns of the coil has a respective beam end, and each beam end has a respective shape of at least one of an angle, arc, or rectangle; or a combination thereof.
