As shown in Figure 3,4, a kind of ribbon high pitch loudspeaker, comprise user oriented, can magnetic conduction and the panel 1 that is provided with perforate 11; Can the rearmounted magnetic conductive board 4 of magnetic conduction; Two magnets 31, described two magnets 31 described panel 1 and rearmounted magnetic conductive board 4 inside and outside between, and interval is arranged; Sound-producing device 32, described sound-producing device 32 is arranged between described two magnets about 31, and described panel 1 and rearmounted magnetic conductive board 4 inside and outside between.In this embodiment, described sound-producing device 32 comprises surface and is provided with the pleated diaphragm 321 of electric conducting material for installing the diaphragm support 322 of described pleated diaphragm.Described diaphragm 321 is for vibration sounding, and described diaphragm support 322 for firm diaphragm, and is convenient to insert in vertical channel and extract, and avoids diaphragm damaged in the process inserted and extract.Concrete, the perforate of described panel 1 is bar hole, and described rearmounted magnetic conductive board 4 is also provided with bar shaped perforate.
The preposition magnetic conductive board of existing sounding diaphragm and panel are integrated by the present embodiment, make the transducer of traditional ribbon-type high-pitch without the need to the extra preposition magnetic conductive board of use respectively and panel, decrease manufacturing cost.In the utility model, panel can adopt the magnetic conductive material the same with rearmounted magnetic conductive board such as iron to make, this panel serves the effect as preposition magnetic conductive board and Users panel simultaneously, thus without the need to using the panel be made up as aluminium of non-magnet_conductible material, the price of metallic iron is significantly less than the price of aluminium, thus reduce further manufacturing cost.
The perforate 11 of acoustic is directly arranged at panel 1 by the present embodiment, the sound of sound-producing device directly 11 to send from the perforate of panel 1, and do not need as the perforate of structure before from preposition magnetic conductive board, sent by the position that hollows out of panel again, thus significantly expand listening area, add spread scope, substantially can be increased to the sector region of 120 °.
Further, the operative axis of described sound-producing device 32 is essentially perpendicular to described panel.That is, sound-producing device 32, panel 1 and rearmounted magnetic conductive board 4 are laminated in together in parallel to each other.
Further, as shown in Figure 6, Figure 7, the longitudinal section of described magnet 31 is trapezoidal, and on it, base 311 outwardly, and bottom 312 inwardly; Described rearmounted magnetic conductive board 4 is squarish, and its dual-side and top margin are provided with chamfering, thus its dual-side aligns with the upper base of described magnet 31, chamfering and the alignment of two waists.After two magnets 31, sound-producing device 32 and rearmounted magnetic conductive board 4 are assembled into one, whole outer contour shape alignment.
Further, as shown in Figure 5, Figure 6, in the inside that described panel 1 and rearmounted magnetic conductive board 4 cover, between described spaced two magnets 31, a vertical channel is formed; Described sound-producing device 32 can insert from described vertical channel and extract fast to assemble.The inside that the present embodiment covers at described panel 1 and rearmounted magnetic conductive board 4, forms a vertical channel between described spaced two magnets 31; Described sound-producing device 32 can insert from described vertical channel and extract fast to assemble, thus reduces manufacture and maintenance cost, and improves applicability.The in particular, for example occasion of outdoor activities, the volume of sound equipment is put into very large usually, and the damage of sounding diaphragm occurs often, present embodiments provides that to change with maintenance convenient.
Further, an edge of described diaphragm 321 is fixed with a pair electric connecting sheet 323, and one of them electric connecting sheet is connected to the one end at the edge of the diaphragm being provided with electric conducting material; Another electric connecting sheet is connected to the other end at the edge of the diaphragm being provided with electric conducting material.By this to electric connecting sheet 323, sound-producing device can be connected tone currents.
Embodiment two
The difference of this embodiment and embodiment one is, as shown in Figure 9, Figure 10, described magnet 31 is arc, and outwardly, string limit 314 inwardly on its arc limit 313; Described rearmounted magnetic conductive board 4 is sub-circular, and its both sides circular arc aligns with the arc limit of described magnet.
By using the structure of the present embodiment, can on the basis of existing trapezoidal magnet, base on it is mended camber thus formed longitudinal section is arc magnet, which increase the area of magnet, to increase the intensity in magnetic field, thus improve the definition of sound, further avoid audio distortions.Because existing preposition magnetic conductive board and panel are integrated by the present embodiment, while the area of magnet is increased, only need corresponding for the area of rearmounted magnetic conductive board increase, because the area of panel itself is enough large, exceed the area of magnet and rearmounted magnetic conductive board, so do not need the area changing panel.In existing structure, front and back due to magnet have preposition magnetic conductive board and rearmounted magnetic conductive board, panel is an independent assembly, if increase the area of magnet to increase magnetic field intensity, then preposition magnetic conductive board also will increase by area thereupon the same as rearmounted magnetic conductive board, and to make its outline align with magnet and rearmounted magnetic conductive board, this will increase cost greatly, therefore, lose more than gain.And the present embodiment, preposition magnetic conductive board and panel are integrated, and this has saved cost, on this basis, increase magnet area to increase magnetic field intensity, only need the area increasing rearmounted magnetic conductive board, and panel need not change, and it also avoid rolling up of cost.
Embodiment three
The difference of this embodiment and embodiment one is, the inner face of described panel 1 also has one for the bonnet (not shown) of coated described magnet 31, sound-producing device 32 and rearmounted magnetic conductive board 4, and described bonnet is bonding with described panel inner surface and seal.The mechanical dimension of this bonnet need consider the accurate control of audio frequency and provide acoustics to isolate for equipressure interference.
In this embodiment, such as this embodiment is used for, in the sound equipment that high pitch and bass arrange jointly, now, providing bonnet as above, by the interference effectively avoiding bass to high pitch.
In this embodiment, when measuring at vertical plane, the height of panel reaches 3mm.In order to ensure the magnetic force coefficient in magnetic field, when measuring at vertical plane, the height of panel is preferably set to 4mm.
Above disclosedly be only preferred embodiment of the present utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
