Wherein, described voice coil loudspeaker voice coil is countless flat solder circles.
Wherein, between described magnetic circuit and bonnet, be provided with sealed film.
Wherein, the shape of described vibrating diaphragm lid is identical with closed chamber shape.
Wherein, the thickness of the degree of depth of described seal groove, diameter and sound ring frame, diameter are in full accord.
Wherein, described bonnet and the thermal column structure that is formed in one, and the material of bonnet and thermal column is aluminium alloy.
Wherein, described through wires hole is provided with the electric wire that binding post is connected with power amplifier.
Beneficial effect of the present invention: the present invention includes magnetic circuit, sound ring frame, bonnet, fan, described magnetic circuit top is bolted with bonnet, described rear tops is provided with countless thermal columns, described thermal column top is bolted with fan, described bonnet bottom offers closed chamber, in described closed chamber, be provided with sound ring frame, described sound ring frame bottom surrounding is surrounded with voice coil loudspeaker voice coil, described sound ring frame top is provided with vibrating diaphragm, described sound ring frame top is provided with the vibrating diaphragm lid in vibrating diaphragm is enclosed in, described vibrating diaphragm tops is provided with binding post, the positive and negative polarities of described voice coil loudspeaker voice coil are connected to respectively on binding post, described bonnet bottom is provided with the seal groove with closed chamber concentric, described bonnet side opening is provided with through wires hole, the present invention adopts flat tin voice coil loudspeaker voice coil, and by being bonnet and the thermal column of aluminum alloy materials, and fan is established at thermal column top, thereby improve voice coil loudspeaker voice coil power, improve tonequality, and raising radiating effect, in addition sound ring frame is sealed in the closed chamber of bonnet, can reach fabulous sealing effectiveness, prevent distorsion or tonequality impact.
