Description
Technical field
The utility model relates to loudspeaker techniques field, particularly relates to a kind of full range height SPL loud speaker.
Background technology
Loud speaker is a kind of very conventional electro-acoustic transducer device, existing coil-moving speaker comprises taper frame, be fixedly installed T iron bottom taper frame, be arranged on frame opening part and the center is fixedly connected with the vibrating diaphragm of cylindrical framework, the cylindrical framework at described vibrating diaphragm center is wound around by a wire voice coil loudspeaker voice coil formed, and is fixedly connected with frame and cylindrical framework respectively and can the sheet that moves both vertically up and down of spacing described cylindrical framework.
Because frame is fixedly connected with a sheet, vibrating diaphragm, the outer end of sheet and the ring of vibrating diaphragm are separately fixed in frame, during moving-coil speaker work, the wire of voice coil loudspeaker voice coil winding has electric current to pass through, according to left hand rule, the winding in magnetic gap can produce and move with flowing through power that current strength conforms to direction and promote vibrating diaphragm.Because sheet and vibrating diaphragm are movabilities on the direction of vibration of vibrating diaphragm, but then have very large rigidity on the direction vertical with direction of vibration, ensure voice coil loudspeaker voice coil windings section can in magnetic gap proper motion and deflection does not occur.
In the especially high-grade electronic organ of electronic organ, need the audible frequency of loud speaker wider, and have very high SPL, but the volume of electronic organ in turn defines the volume of loud speaker, if realizing full range height SPL under the prerequisite of small size is the technical problem being badly in need of solving.
Utility model content
The purpose of this utility model is the technological deficiency for existing in prior art, and provides a kind of full range height SPL loud speaker.
The technical scheme adopted for realizing the purpose of this utility model is:
A kind of full range height SPL loud speaker, comprise taper frame, be fixedly installed the magnet bottom taper frame, be arranged on frame opening part and the center is fixedly connected with the cone of cylindrical framework, connect the ring of cone top edge and frame opening, the voice coil loudspeaker voice coil that described cylindrical framework is formed is wrapped in by a wire, to be fixedly connected with frame and cylindrical framework respectively and can the centring disk that moves both vertically up and down of spacing described cylindrical framework, and dust cover, described ring is PU material, described cone thickness is at 0.3-0.5mm, described voice coil loudspeaker voice coil is entwined by two layers, wire, the magnetic flux of described magnet is not less than 10000Gs, described dust cover is fixedly installed on voice coil loudspeaker voice coil top and lower limb is fixedly connected with cone.
The thickness of described dust cover is at 0.1-0.2mm.
The opening diameter of described frame is at 120mm.
Compared with prior art, the beneficial effects of the utility model are:
Loud speaker of the present utility model, increases the magnetic flux of magnet, improves the winding density of voice coil loudspeaker voice coil guiding, controls the quality of vibrational system to realize high SPL demand simultaneously, wherein, adopts the ring of PU material can ensure lightly can ensure the powerful of bass again.
Accompanying drawing explanation
Figure 1 shows that the structural representation of full range height SPL loud speaker of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, loud speaker described in full range height SPL loud speaker of the present utility model is 5 inch, namely opening diameter is at 120mm, it comprises taper frame 1, sheet-pile 2, be fixedly installed the magnet 3 bottom taper frame, be arranged on frame opening part and the center is fixedly connected with the cone 4 of cylindrical framework, connect the ring 5 of cone top edge and frame opening, the voice coil loudspeaker voice coil 6 that described cylindrical framework is formed is wrapped in by a wire, and to be fixedly connected with frame and cylindrical framework respectively and can the centring disk 7 that moves both vertically up and down of spacing described cylindrical framework, described ring is PU material, described cone thickness is at 0.3-0.5mm, described voice coil loudspeaker voice coil is entwined by two layers, wire, the magnetic flux of described magnet is not less than 10000Gs, magnet prepared by the DM4229 model ferrite as the production of Dongyang, Zhejiang magnetic material company.Dust cover 8 is fixedly installed on voice coil loudspeaker voice coil top and lower limb is fixedly connected with cone, and as bonding connection, the thickness of described dust cover is at 0.1-0.2mm.Dust cover can be dust-proof and improve high frequency frequency response.
Loud speaker of the present utility model, increase the magnetic flux of magnet, improve the winding density of voice coil loudspeaker voice coil guiding, control the quality of vibrational system to realize high SPL demand simultaneously, wherein, adopt the ring of PU material can ensure lightly can ensure the powerful of bass again, curve basin selected by cone, dust cover improves high frequency response, exports so realize full range.
The above is only preferred implementation of the present utility model; it should be noted that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
