Description
Technical field
The present invention relates to a kind of magnetic circuit system, more particularly relate to a kind of magnetic circuit system being applied to speaker, belong to loudspeaker techniques field.
Background technology
Along with the development of sound reinforcement system and universal, market is more and more stronger to the demand of overlength distance transfer voice and high-power specialty speaker, it is therefore desirable to the horn loudspeaker that developed horse power is big, lightweight, volume is little, price is low, highly sensitive carrys out meeting the market requirement.At present, powerful speaker caloric value is the biggest, and this partial heat is concentrated mainly on magnetic circuit system, and unusual common reason in high temperature failure numerous cause of damage that are speaker, it constrains speaker raising in terms of power to a great extent, and then affect acoustic performance and the reliability of speaker, in order to be able to improve the power of speaker, it is necessary for developing the magnetic circuit of loudspeaker with high cooling efficiency, improve the radiating efficiency of magnetic circuit system simultaneously, the operating temperature that can make speaker is lower, and then the magnet that heatproof is low can be selected, the parts such as voice coil loudspeaker voice coil, save cost to a certain extent.
Summary of the invention
Goal of the invention:
Present invention aim at for the deficiencies in the prior art, it is provided that the open magnetic circuit system of a kind of high-power and big amplitude state adapting to speaker.
Meanwhile, the present invention also provides for a kind of speaker comprising above-mentioned magnetic circuit system solving the problems referred to above.
Technical scheme:
A kind of open magnetic circuit system of the present invention, including magnetic conduction upper plate, magnet, magnetic conduction core, magnetic conductor bowl, described magnetic conductor bowl is bowl-shape, described magnet is arranged at inside described magnetic conductor bowl, described magnetic conduction core is arranged at the top of described magnet, described magnetic conduction upper plate is arranged at the periphery of described magnetic conduction core, and the outside of described magnetic conduction core is provided with at least one breach caved inward.
Being further defined to of technical solution of the present invention, the breach arranged outside described magnetic conduction core is at least 2, and is uniformly distributed along the circumference of described magnetic conduction core.
Further, described magnetic conduction core, magnet and described magnetic conductor bowl all use the structure of hollow, and described hollow structure is interconnected formation gas channel.
Further, the hollow structure of described magnetic conduction core uses chamfering sample.
Further, sidewall and the bottom even of described magnetic conductor bowl arranges passage.
The present invention also provides for another technical scheme: a kind of speaker comprising above-mentioned open magnetic circuit system.
Being further defined to this technical scheme, described speaker is horn loudspeaker, electromotive force cone loudspeaker.
Beneficial effect: a kind of open magnetic circuit system that this utility model provides, arranges breach on magnetic conduction core, it is to avoid the glue that goes between under speaker amplitude state high-power, big collides with magnetic conduction core, increases the power capacity of magnetic circuit system；Further, pore is set by the structure of hollow, magnetic conductor bowl, makes air-flow to discharge smoothly, take away heat, thus improve the radiating efficiency of magnetic circuit system, and the hollow structure of magnetic conduction core uses chamfering pattern, it is to avoid air-flow produces turbulent flow affects the normal vibration of sound film；Speaker of the present utility model has the features such as lightweight, thickness is thin, price is low, magnetic energy is big, heat dispersion is excellent, low-frequency effect is good, fundamentally improves speaker temperature under high power work state.
