Embodiment
For making the object of the invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, to further explain of the present invention.
Please refer to Fig. 1, the loudspeaker that the embodiment of the invention 1 provides comprise support 101, magnet fixed mount 102 resonant rings 103.Among this embodiment, the center of circle of support 101, magnet fixed mount 102 resonant rings 103 is all on same straight line.
Fig. 2-Fig. 5 is four kinds of various structure sketch mapes of the resonant ring 103 of present embodiment, and is concrete, and Fig. 2 is circular-arc responant diaphragm sketch map; Fig. 3 is horizontal responant diaphragm sketch map; Fig. 4 is single broken line responant diaphragm sketch map; Fig. 5 is a dual slope responant diaphragm sketch map.
Wherein, common support 101 all is made up of steel material, in the process that loudspeaker use, mainly plays support and fixing loudspeaker, and the bulging paper of loudspeaker and the outer edge of support 101 link together, and form a cone shape, are used for sounding.
The center of support 101 and the outer edge center of circle can combine with the magnet fixed mount on same straight line; The center of support 101 and the connecting portion between the outer edge can be processed different shapes according to different sound equipments, and in the process of using, the lead of loudspeaker often is fixed on connecting portion.
Magnet fixed mount 102 is a U iron, is the hollow cylindrical structure of end sealing; And U iron and support 101 are fixing; The axis of U iron and the central lines of said support are with the support structure that is combined as a whole.As the necessary structure of magnetic horn in conventional, but the U iron inside interior magnet of the hollow cylindrical structure of end sealing, voice coil loudspeaker voice coil, washer etc. are used for the device of sounding.
Above-described support 101, magnet fixed mount 101 have been formed the basic building block of sound horn device; In the process of loudspeaker work; After the energising, be arranged in the inner voice coil loudspeaker voice coil of U iron and play ripple, so just make and rousing the air compression between paper and the U iron or upholding in effect that has received electric field force in magnetic field and then generation vibration; And then drive drum paper and vibrate together, so just accomplished the process that electric energy converts acoustic energy into.
Be fixed on the resonant ring 103 of support 101 outer edges, common fixed form is for being bonded at 101 outer edges with the interior ring of resonant ring 103 is glutinous, and wherein, support 101 outer edges overlap with resonant ring 103 ring heart lines, makes original loudspeaker profile obtain amplification on intuitively.Resonant ring 103 is made up of responant diaphragm and fixed support flanging two parts.Generally speaking; Loudspeaker drum paper and dust cover place face are called the front of loudspeaker, and the front of loudspeaker is grooves of a cone shape, the opening direction of groove be called loudspeaker towards; The protrusion direction of the responant diaphragm of resonant ring 103 can be identical with the direction of loudspeaker, also can be opposite.
The cross section of resonant ring 103 is circular arc, linear, single broken line shape, many broken lines shape etc., and the cross section here refers to through intersecting the friendship face that forms between the plane of reference of resonant ring 103 ring heart lines and the resonant ring 103.
In the process of sound horn, electrical conductor receives the effect of power in magnetic field, thus vibration, and then make drum paper air be compressed or uphold, and then make whole bulging paper and voice coil loudspeaker voice coil vibrate, ring vibration sound wave in producing; Because the outer edge at support 101 has resonant ring 103, air driven resonant ring 103 vibrations that are compressed and uphold in the drum paper form outer shroud vibration sound wave; Can produce resonance between interior ring vibration sound wave and the outer shroud vibration sound wave, and then not increase under the situation of driving voltage, can improve the pronunciation volume of loudspeaker or produce stereo sound effect.
Simultaneously, because resonant ring 103 is nonmetallic materials, has so just reduced sound in support 101 outer edge losses, thereby made electro-acoustic conversion efficiency be improved.
The fixed support flanging that is positioned at the responant diaphragm outer of ring-type is fixed up with the audio amplifier cavity and forms the bearing edge of loudspeaker, and the fixed support flanging can be adopted with the responant diaphragm identical materials of ring-type and make.
The production method of a kind of loudspeaker that provide of present embodiment comprises, magnet fixed mount 102 is fixed on the support 101, and forms core component; The inside edge of said resonant ring 103 is cooperated and fixing with the outer edge of said support 101, thereby process interior magnetic horn.
Please refer to Fig. 6, the loudspeaker that the embodiment of the invention 2 provides comprise support 601, magnet fixed mount 602 resonant rings 603.Among this embodiment, the functional configuration of support 601 and resonant ring 603 and annexation are identical with the foregoing description 1 described support 101 and resonant ring 103, do not do and give unnecessary details, and only magnet fixed mount 202 are done further explanation and explanation.
Magnet fixed mount 602 is a T iron, and T iron is by the location-plate of the axis normal of a central shaft and extended planar and said central shaft; One end and the said location-plate of central shaft are fixed; In the assembling process of loudspeaker, T iron central shaft stretches in the centre bore of annular magnet.
The production method of the loudspeaker that the embodiment of the invention 2 provides comprises, magnet fixed mount 602 is fixed on the support 601, and forms core component; The inside edge of said resonant ring 603 is cooperated and fixing with the outer edge of said support 601, thereby process outer magnetic horn.
The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being made, is equal to replacement, improvement etc., all should be included within the scope that the present invention protects.
