Abstract
The utility model discloses an ultrahigh-power loudspeaker. T-shaped iron is formed by tightly assembling an upper piece and a lower piece; an upper and lower short-circuit radiating ring is assembled at the matched part and is positioned in a voice coil; a radiator is arranged above the upper piece of the T-shaped iron; a reinforcing ring is adhered at the joint of a lower spring plate and the voice coil; and a lower dustproof cap is provided with a spherical surface protruding towards the interior of the voice coil, the stepped wall of the lower dustproof cap and the inner wall of the voice coil are matched and fixed, and the outer edge of the lower dustproof cap and an upper opening of the voice coil as well as a cone are respectively fixed. A sample test proves that the phenomenon that a fault is caused due to radiating and degumming is avoided under the condition that the loudspeaker works at extremely high power for a long time.
Description
Technical field
The utility model belongs to the loud speaker group in International Patent Classification (IPC), i.e. HO4R, particularly supersound projector.
Background technology
Public super high power loud speaker has basin frame, magnet steel, clamping plate, T iron, short circuit cover, voice coil loudspeaker voice coil, cone, upper and lower dust cap and upper and lower latch plate at least.Because operating power is very big, it is more that heat is gathered in generation, therefore under the prerequisite that guarantees mechanical property, should dispel the heat as early as possible, must consider to save and use material.For example dust cap is used two up and down, but is positioned at following meeting generation gluing difficulty like this, very easily comes unstuck here; And for example, the effect of short circuit cover is undesirable, when long-time extreme power is worked, can cause T iron rubescent; For increasing heat radiation clamping plate are processed pie for another example, consumptive material is serious; The inner heat accumulation of voice coil loudspeaker voice coil is exceedingly fast in addition, is difficult to leave.Should take all factors into consideration in manufacturing and designing in a word.Through retrieval, new technical scheme fails to retrieve.Say that definitely these problems have become the biggest problem of this aspect in the electroacoustic industry.
The utility model content
The purpose of the utility model provides a kind of super high power loud speaker, and it can be at extreme power, when using for a long time, be difficult for coming unstuck, and voice coil loudspeaker voice coil is not yielding, and rapid heat dissipation is economized with material.
The new solution that realizes above-mentioned purpose is following:
A kind of super high power loud speaker contains basin frame, magnet steel, T iron, clamping plate, voice coil loudspeaker voice coil, cone, upper and lower dust cap and upper and lower latch plate at least, on the axis of said T iron shaft through-hole is arranged, and the spiracle group is arranged on the voice coil loudspeaker voice coil, it is characterized in that:
The cooperation of T iron center pillar bottom is with down the short circuit heat dissipating ring, and the cooperation of center pillar top is with the short circuit heat dissipating ring;
The short annulus boss that the one processed is arranged on the circumference above the clamping plate centre bore;
Following dust cap has protruding in the inner sphere of voice coil loudspeaker voice coil, and its step wall and voice coil loudspeaker voice coil inwall suitable for reading coincide and fixes, the outer rim of following dust cap respectively with voice coil loudspeaker voice coil suitable for reading and cone fix;
There is stiffening ring the junction of lower spring plate and voice coil loudspeaker voice coil above it, between stiffening ring and the voice coil loudspeaker voice coil space is arranged, and in this space bonding agent is arranged;
The top that the T iron of axis hole is arranged, close-fitting also is fixed with radiator.
By the sample that such scheme is processed, have more advantage: stiffening ring and following dust cap following protruding guaranteed bigger bonding plane, so has been difficult for coming unstuck; Clamping plate are with material province and same magnetic conduction and radiating effect are arranged; The short circuit heat dissipating ring has beyond thought bass performance and radiating effect up and down; The radiating effect of radiator is good.In fatigue test or ageing test, never break down in a word.
