Abstract
The utility model relates to a high-power loudspeaker magnetic circuit, comprising a magnetic-conduction bowl which is bonded and fixed with a magnetizer and a magnetic-conduction upper plate, and a magnetic-conduction core which is bonded and fixed with the magnetizer; the high-power loudspeaker magnetic circuit further comprises a bolt, the magnetic-conduction core is a round-disc body, two grooves are systematically arranged on the surface of the magnetic-conduction core, a through hole is arranged at the circular center, and the bolt penetrates through the magnetic-conduction core and the magnetizer to be fixed with the magnetic-conduction bowl sequentially. The high-power loudspeaker magnetic circuit has the beneficial effects that: the structure has the characteristics of high mechanical strength, low price, high magnetic energy, good heat-radiation performance and good low-frequency effect; the high-power loudspeaker magnetic circuit can be widely applied to horn speakers with strict requirements to power capacity. The purpose of the proposal I is to increase the mechanical reliability importantly, and the purpose of the proposal II inclines to good heat-radiation performance, thereby being suitable for occasions with strict requirements to power capacity.
Description
Technical field
The utility model relates to magnetic circuit of loudspeaker, particularly a kind of a kind of supersound projector magnetic circuit that is used for horn loudspeaker, electrodynamic type cone loudspeaker, tweeter.
Background technology
Along with the development of sound reinforcement system is popularized, market is more and more stronger to the demand of overlength distance transfer voice and high-power professional loud speaker, therefore needs developed horse power horn loudspeaker big, in light weight, that volume is little, price is low, highly sensitive to come meeting the market requirement.Tradition supersound projector caloric value is very big, and this part heat mainly concentrates on magnetic circuit system, and very general reason in cause thermal damage numerous sources of damage that are loud speaker, it has restricted the raising of loud speaker aspect power to a great extent.
Summary of the invention
Deficiency in view of the prior art existence, the utility model provides a kind of usefulness magnetic circuit that the alnico magnet that original loud speaker adopts is formed, improve modular construction the power of loudspeaker capacity can be improved more, a kind of supersound projector magnetic circuit that still having simultaneously under the condition that magnetic energy does not reduce can weight reduction, reduce cost.
The utility model for achieving the above object, the technical scheme of being taked is: a kind of supersound projector magnetic circuit, comprise the magnetic conductor bowl that is adhesively fixed with magnetic conductor, magnetic conduction upper plate, the magnetic conduction core that is adhesively fixed with magnetic conductor, it is characterized in that: also comprise bolt, described magnetic conduction core is a wafer body, is arranged with two grooves on its face, the place is provided with through hole at the circle core, and described screw bolt passes magnetic conduction core, magnetic conductor and magnetic conductor bowl are fixed.
A kind of supersound projector magnetic circuit, comprise the magnetic conductor bowl that is adhesively fixed with magnetic conductor, magnetic conduction upper plate, the magnetic conduction core that is adhesively fixed with magnetic conductor, it is characterized in that: described magnetic conduction core is the disk shape, on its face, be arranged with two grooves, the place is provided with through hole at the circle core, and the suitable for reading of through hole is bell mouth shape; Described magnetic conductor bowl bowl bottom center is provided with through hole, and the through hole end opening is a bell mouth shape, is provided with several through holes along bowl bottom one circle, is provided with several through holes along bowl wall one circle.
The beneficial effects of the utility model are: characteristics such as this structure has the mechanical strength height, price is low, magnetic energy is big, heat dispersion is excellent, low-frequency effect is good.Can be widely used in power capacity has the horn speaker of strict demand.Such scheme one biases toward the increase Mechanical Reliability; Scheme two biases toward better heat dispersion, is applicable to the place strict to power capacity.

Embodiment
As shown in Figure 1, 2, a kind of supersound projector magnetic circuit, comprise the magnetic conductor bowl that is adhesively fixed with magnetic conductor, magnetic conduction upper plate, the magnetic conduction core that is adhesively fixed with magnetic conductor, also comprise bolt 3, magnetic conduction core 1 is a wafer body, is arranged with two groove 1-1 on its face, the place is provided with through hole 1-2 at the circle core, and bolt 3 passes magnetic conduction core 1 successively, magnetic conductor 4 is fixing with magnetic conductor bowl 2.
Shown in Fig. 3,4,5, a kind of supersound projector magnetic circuit, comprise the magnetic conductor bowl that is adhesively fixed with magnetic conductor, magnetic conduction upper plate, the magnetic conduction core that is adhesively fixed with magnetic conductor, magnetic conduction core 1 is the disk shape, be arranged with two groove 1-1 on its face, the place is provided with through hole 1-2 at the circle core, and the suitable for reading of through hole 1-2 is horn mouth 1-3 shape; Magnetic conductor bowl 2 bowl bottom centers are provided with through hole 2-1, and through hole 2-1 end opening is horn mouth 2-2, are provided with eight through hole 2-3 along bowl bottom one circle, are provided with eight through hole 2-4 along bowl wall one circle.
1, on magnetic conduction core 1, has two groove 1-1 (breach), can avoid that loud speaker is high-power, lead-in wire glue and magnetic conduction core bump the large amplitude state down.
2, magnetic conduction core 1 adopts hollow structure, and air-flow can be discharged smoothly by this hole, and then takes away heat.
3, get through hole 2-3,2-4 on magnetic conductor bowl 2, air-flow can be discharged smoothly by this hole, and then takes away heat.
4, the mesopore that is made of magnetic conduction core 1, magnetic conductor 4, magnetic conductor bowl 2, aperture, two ends are horn mouth (big chamfering) style, avoid air-flow to produce the normal vibration that turbulent flow influences the sound film.
