The utility model content
The utility model mainly is to solve existing problem in the above-mentioned prior art, and a kind of flat film loudspeaker is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of flat film loudspeaker, comprise support, in support, be provided with yoke, magnet is arranged in the yoke, is provided with plane diaphragm on magnet top, and protecting cover buckles on support, it is characterized in that: on support, also be provided with substrate, plane diaphragm is arranged on the substrate, is furnished with voice coil on the two sides of this plane diaphragm, and described voice coil is arranged around the center spirality.Voice coil loudspeaker voice coil is not set in the utility model, but adopt voice coil loudspeaker voice coil and vibrating diaphragm two-in-one, forming the vibrating diaphragm that the two sides is provided with voice coil, they are different with common loudspeaker to have different sounding principles, instigated in magnetic gap by charged vibrating diaphragm comprehensively, this vibrating diaphragm is thin and light, and active force does not have the difference of phase place, the conversion efficiency height, the frequency response broadness, distortion is little, not only number promotion but also control well, and transient response is very good.
As a kind of preferred version of such scheme, described support is middle perforation, and the edge contracts in successively and is formed with radially anchor ring and second step structure of anchor ring radially of the first axial anchor ring, the second axial anchor ring, first.
As a kind of preferred version of such scheme, described yoke is embedded in by in second groove that radially anchor ring and the second axial anchor ring form, the yoke upper end with first radially anchor ring flush.
As a kind of preferred version of such scheme, described substrate protrudes on the ring bodies cylindrical and is formed with the connection wing circlewise, connects the wing and is provided with the tie point that is connected with voice coil.
As a kind of preferred version of such scheme, described substrate is arranged on first radially on the anchor ring, and the described first axial anchor ring is provided with breach, and the connection wing on the substrate is passed by indentation, there.
As a kind of preferred version of such scheme, protecting cover is provided with and evenly is provided with through hole.
The plane diaphragm of voice coil is arranged on the two sides that the utility model adopts voice coil loudspeaker voice coil and vibrating diaphragm two-in-one to form, structure is thin, light weight, and then its active force does not have the difference of phase place, the conversion efficiency height, the frequency response broadness, distortion is little, not only number promotion but also control well, transient response is very good, this loadspeaker structure advantages of simple, production technology is simple, and production cost is low.
