Abstract
The utility model discloses a coil-moving speaker with full-symmetry structure comprising a magnet, a soft iron, a support bracket and a diaphragm and a voice coil. The upper and the lower portions are both composed of an annular magnet, a circular soft iron and a support bracket, whose structures are identical and symmetrical; two paraboloid diaphragms have the same size in the middle; both sides are adhered with the two voice coils with the same size; the diameters of the voice coils are enlarged; an involute reflexion ring is positioned on the loudspeaker opening; the entire loudspeaker structure is symmetrical. The utility model is simplicity and utility, and it can decrease the aberration to the lowest degree.
Description
The present invention relates to a kind of sound equipment, especially a kind of total all is holosymmetric coil-moving speaker.
Tradition moving-coil type gas loudspeaker distortions degree is higher, and people have thought that a lot of methods solve, and for example: the sound basin adopts the fine braiding of silicon carbide/polypropylene carbon, bulletproof cloth etc., but because traditional pyramidal structure unreasonable, various distortions are difficult to further reduce.
The purpose of this utility model provides the coil-moving speaker that a kind of total all is a symmetry, can make the inherent distortion of traditional coil-moving speaker drop to minimum level.
The utility model is by toroidal magnet, annular soft iron, support, vibrating diaphragm, compositions such as voice coil loudspeaker voice coil.
Elaborate below in conjunction with accompanying drawing.
Fig. 1 is a cross-sectional view of the present utility model.
The utility model shown in Figure 1 is upper and lower by equirotal toroidal magnet 2, and annular soft iron 3 and support 6 constitute.On, two partial structure are identical and symmetrical down, toroidal magnet 2 is clipped between two annular soft iron 3 and with support 6 and links, be positioned at the edge of parabolic vibrating diaphragm 7, on, be two equirotal parabolic vibrating diaphragms 7 in the middle of two parts down, the equirotal voice coil loudspeaker voice coil of vibrating diaphragm 7 both sides and two 5 is bonding, voice coil loudspeaker voice coil 5 is outer middle bonding with two equirotal pair of locating branch slices 4, the diameter of voice coil loudspeaker voice coil 5 strengthens than traditional voice coil loudspeaker voice coil, each coil with two lines and around, ring 8 one ends and last vibrating diaphragm 7 link, and the other end and is positioned at speaker port can reduce the ante-chamber effect on upper end soft iron 3 involute reflection circle 9 and links.On the soft iron 3 of upper end a screw hole 1 is arranged.
After having adopted such structure,, just little to the reflection interference of vibrating diaphragm because magnet positions is far away than conventional loudspeakers from the distance of vibrating diaphragm.Adopted the dual paraboloid vibrating diaphragm, strengthened voice coil loudspeaker voice coil, driven, realized comprehensive vibration from the vibrating diaphragm edge.The vibrating diaphragm that has overcome conventional loudspeakers is difficult to reach synchronous vibration during from middle driving work, and occur cut apart oscillation phenomenon.The utility model is simple and practical, distortion can be dropped to minimum level.
