Embodiment
For can further understand feature of the present utility model and technology contents, refer to following about detailed description of the present utility model and accompanying drawing, but institute's accompanying drawings only provide reference and explanation use, is not used for doing any restriction to interest field of the present utility model.
Refer to Fig. 1 to Fig. 5, its embodiment being this creation, the present embodiment is a kind of loud speaker 100.As shown in Figure 1, 2, loud speaker 100 consists essentially of supporting construction 1, vibrating diaphragm 2 and a coil 3.
Above-mentioned supporting construction 1 is such as based on made by the insulating material such as plastics, and its outline is roughly in flat rectangle.Further, supporting construction 1 can be divided into the first half 11 and a Lower Half 12 further, and the first half 11 of supporting construction 1 is formed with an opening 111.
Above-mentioned vibrating diaphragm 2 is located at the first half 11 of supporting construction 1, and is positioned at the periphery of opening 111, and its outline is roughly in flake.As shown in Figure 4,5, vibrating diaphragm 2 has the magnetic material layer 22 (magnetic layer) that a basalis 21 (substrate layer) and is formed at basalis 21 surface.Specifically, the basalis 21 of vibrating diaphragm 2 can be such as made by one of them or the combination such as paper pulp, cloth, silk, fiber crops, synthetic fibers, pottery, metal, plastics, high molecular polymer, but not as limit.In addition, the magnetic material layer 22 of vibrating diaphragm 2 such as can be made up of multiple elements such as iron (Fe), chromium (Cr), cobalt (Co), neodymium (Nd), boron (B), and its proportioning can adjust according to actual design demand.Furthermore, physical gas phase deposition technology (PVD) or chemical vapour deposition technique (CVD) can be utilized, make magnetic material layer 22 be formed at basalis 21 surface, and then make vibrating diaphragm 2 have magnetic.
In another embodiment, above-mentioned vibrating diaphragm 2 is single piece type alloy vibrating diaphragm.Specifically, vibrating diaphragm 2 is closed sheet metal for material directly synthesizes a slice by alloy technology with iron (Fe), chromium (Cr), cobalt (Co), neodymium (Nd), boron (B), and then makes vibrating diaphragm 2 have magnetic.
The Lower Half 12 of supporting construction 1 is located at by above-mentioned coil 3.Thin portion, Lower Half 12 centre of supporting construction 1 is formed with a positioning convex column 121, and namely coil 3 is fixed on the Lower Half 12 of supporting construction 1 through positioning convex column 121 location.In addition, as shown in Figure 3,4, both coil 3 and vibrating diaphragm 2 are that interval is arranged relative to one another, and alternatively coil 3 corresponds to vibrating diaphragm 2 abreast, and form a minimum spacing each other.Moreover coil 3 is the flat coil of a flattening design.
The loud speaker 100 of the present embodiment more can include an outstanding limit 4, and outstanding limit 4 is a soft outstanding limit, such as, can be that silica gel hangs limit, cloth hangs limit, rubber hangs limit or foam hangs limit etc.Further, outstanding limit 4 is connected to the periphery of vibrating diaphragm 2 and the periphery of opening 111.In the present embodiment, outstanding limit 4 hangs limit for silica gel, and hangs limit through aforementioned silica gel, and the periphery of the periphery of vibrating diaphragm 2 and opening 111 is glued together each other.
The loud speaker 100 of the present embodiment is in time assembling, first coil 3 is put into the Lower Half 12 in supporting construction 1, and the Lower Half 12 of supporting construction 1 is fixed in location, through tool, vibrating diaphragm 2 is put into opening 111 again, and in the periphery of vibrating diaphragm 2 and the week of opening 111 intermarginal reserved runner inject outstanding sapwood material, withdrawing pattern after it solidifies and make vibrating diaphragm 2 can pass through outstanding limit 4 with the first half 11 of supporting construction 1 to be combined, finally the first half 12 of supporting construction 1 to be carried out gluing together namely completing assembling with the Lower Half of supporting construction 1.
The loud speaker 100 of the present embodiment is when start, and its start relation is roughly as described below:
When coil 3 imports electric current, according to Maxwell relational expression, coil 3 can change electromagnetic field along with importing current phase, then according to Ampere's right-handed screw rule, and then learn magnetic direction.Therefore, the coil 3 being positioned at below generates an electromagnetic field through the electric current imported, and directly with to be positioned at above coil 3 and the magnetic vibrating diaphragm 2 of tool produces electromagnetic induction, due to two like magnetic poles repel each other and the characteristic that there is a natural attraction between the sexes, and make vibrating diaphragm 2 up-down vibration, produce sound to extrude air.It is worth mentioning that in addition, because coil 3 corresponds to vibrating diaphragm 2 abreast, and the magnetic direction that produces when importing electric current of coil 3 can perpendicular to vibrating diaphragm 2 and magnetic force directly acts on vibrating diaphragm 2, and make electro-acoustic conversion efficiency better, can reduce the energy loss that tradition drives vibrating diaphragm to cause through voice coil loudspeaker voice coil up and down.In addition, under the prerequisite of same volume (dB value is identical), loud speaker 100 power consumption of the present embodiment can be less, and alternatively, under the prerequisite of bearing equal-wattage, volume can be larger.
In sum, the loud speaker of the present embodiment, its vibrating diaphragm has magnetic material layer, so be different from the vibrating diaphragm of conventional paper stock, plastics or metal material, makes the vibrating diaphragm of the present embodiment have magnetic.Moreover, the magnetic vibrating diaphragm of the present embodiment tool is positioned at the top of supporting construction, and coil is positioned at the below of supporting construction, be different from conventional voice coil loudspeaker voice coil be positioned at the top of supporting construction and be connected to vibrating diaphragm, and magnetic goes back to the below that assembly is positioned at supporting construction, the loud speaker of the present embodiment is removed from arrange magnetic to go back to space occupied by assembly.Again, the coil of the present embodiment and vibrating diaphragm are arranged in relatively interval each other, and form minimum spacing each other, are different from conventional voice coil loudspeaker voice coil and must retain the stroke space that enough voice coil loudspeaker voice coils move up and down in order to drive vibrating diaphragm.Therefore, the loud speaker of the present embodiment is through flake and the magnetic vibrating diaphragm of tool, and corresponding configuration and be the coil of flat, the magnetic being removed from conventional loud speaker goes back to the space occupied by assembly and voice coil loudspeaker voice coil, effectively can reduce thickness and reach the demand of more lightening design.
The foregoing is only this novel better possible embodiments, non-ly therefore limit to the scope of the claims of the present utility model, so all utilization the utility model specifications and accompanying drawing equivalence techniques change that content is carried out, be all contained in scope of the present utility model.
