Description
Technical field
The present invention relates to loud speaker, particularly a kind of flip-over type loud speaker.
Background technology
Along with the quick progress of science and technology, human life quality also promotes thereupon, and traditional large-sized iconoscope TV is replaced by the LCD TV of the lightweight of today, slimming or LED TV.And liquid crystal of new generation or LED TV are more conceived to the thin design of screen sizes, profile is as simply agile in same width picture frame, but first dwindle with the relative attenuation of volume of LCD TV, it is very limited that internal structural space becomes, traditional loadspeaker structure be magnetic circuit be placed on vibrational system after, promote vibrational system by the vibration of voice coil loudspeaker voice coil and complete sounding, its loud speaker tonequality is good but assembly volume is larger, be unfavorable for being configured in the limited liquid crystal in inner space or LED TV, if for the just necessary relative decrease loudspeaker size of arranging in pairs or groups reluctantly, but its sound wave sending just has no idea effectively to resonate, cause exporting audio desirable not to the utmost, and cannot take into account the dual enjoyment of vision and the sense of hearing, for its maximum shortcoming.
Summary of the invention
Technical problem to be solved by this invention is: for above-mentioned the deficiencies in the prior art, a kind of flip-over type loud speaker is provided, can effectively reduce vibrating diaphragm height, significantly reduce loudspeaker combination volume, to insert in the limited electric equipment products in inner space, can stablize again voice coil loudspeaker voice coil vibration, produce good acoustical quality.
The present invention for achieving the above object, the technical scheme adopting is: a kind of flip-over type loud speaker, comprise the magnetic circuit group that is provided with basin frame, dust cover, locating branch slice, the cone that is provided with ring, the voice coil loudspeaker voice coil of weld tabs and is fixed with successively pad I, magnet, pad II formation in U iron groove, it is characterized in that: also comprise magnetic circuit support, described magnetic circuit support is structure as a whole, comprise interior ring and outer shroud, interior ring and outer shroud are connected as a single entity by four horizontal supports; The base ring of the cylindrical of described locating branch slice and basin frame bonds together, the pressed on ring of the cylindrical of described cone and basin frame bonds together, centre bore and dust cover that one end of described voice coil loudspeaker voice coil penetrates cone and locating branch slice successively bond together, one end of voice coil loudspeaker voice coil and cone and locating branch slice bond together simultaneously, one end of described magnetic circuit group is bonded in the interior ring of magnetic circuit support, the outer shroud of magnetic circuit support and the cylindrical of cone bond together, and it is matched in clearance that the other end of voice coil loudspeaker voice coil is placed between the gap of the magnetic circuit group U iron groove corresponding with it and pad I, magnet, pad II.
The invention has the beneficial effects as follows: the present invention is a kind of thin speaker structure-improved, and it is flip-over type thin speaker that magnetic circuit is placed on vibrational system front, because magnetic circuit is placed cone recess, basin frame is a short disk body, and whole height is reduced.This flip-over type thin speaker has used neodymium iron boron high-performance magnet, adopts internal magnetic type magnetic line structure, thereby has reduced inner space, also makes loud speaker obtain enough magnetic energy levels.This loud speaker has also utilized paper cone recess to place magnetic circuit, both saved television set space, can show again good acoustical quality, make that thin speaker is real to be used in the sound system of LCD TV or LED TV, Costco Wholesale also can reduce greatly simultaneously.
