Super-power loudspeaker

Abstract

The invention discloses a super-power loudspeaker. Each T-yoke is formed by tight matching of an upper piece and a lower piece; an upper short-circuit radiating ring and a lower short-circuit radiating ring are matched tightly in each matching position and are placed in a voice coil; a radiator is arranged on each upper piece of each T-yoke; a reinforcing ring is bonded above a position where each lower spring plate is bonded with the voice coil; and a lower dust cap is provided with a spherical surface bulging to the inside of the voice coil, the step wall of the lower dust cap is matched and fixed with the inner wall of the voice coil, and the outer edge is fixed with the upper opening and a paper cone of the voice coil respectively. Experiments prove that a sample of the super-power loudspeaker cannot fail caused by heat radiation and degumming under conditions of extreme power and long-time operation.

Description

technical field

[0001] The present invention belongs to the loudspeaker subclass in the International Patent Classification Table, that is, HO4R, and particularly relates to high-power loudspeakers. Background technique

[0002] Known public ultra-high-power loudspeaker, at least basin support, magnetic steel, splint, T iron, short-circuit cover, voice coil, paper cone, upper and lower dustproof caps and upper and lower spring plates. Due to the huge working power, there is a lot of accumulated heat. Therefore, under the premise of ensuring the mechanical properties, heat dissipation should be carried out as soon as possible, and material saving should also be considered. For example, two upper and lower dust caps are used, but it will be difficult to apply glue on the lower part, and it is easy to degumming here; another example, the effect of the short-circuit cover is not ideal, and the T-iron will become red when it is operated at extreme power for a long time; Another ...
