Embodiment Construction

[0056] The invention discloses a new type of electromagnet, which includes a coil group made by semiconductor technology. Because the coil group is etched by semiconductor technology, the line pitch in the coil group is extremely small, so that the magnetic field of each coil in the coil group can be directly superimposed. Compared with the wire coil of the existing electromagnet, the finished product of the coil group is extremely small in size and light in weight, so that the proportion of the volume and mass of the electromagnet to the power is greatly reduced.

[0057] On the basis of the above, in order to reduce the reluctance of the electromagnet and strengthen the magnetic force lines, the electromagnet also includes a magnetic material. Such as figure 1As shown, the magnetically permeable material can be set in the coil group; as figure 2 and image 3 As shown, the magnetically permeable substance can also be arranged on the coil group; as Figure 4 As shown, the...

Abstract

The invention relates to a novel electromagnet, a preparation method thereof, and a magnetic structure of a loudspeaker, and the novel electromagnet comprises a coil assembly made by adopting a semiconductor technology. Because the coil assembly is formed by etching by adopting a semiconductor technology, the line distance in the coil assembly is extremely small, and the magnetic fields of the coils in the coil assembly can be directly superposed. Compared with a wire coil of an existing electromagnet, the finished product body of the coil assembly is very small, the mass is very light, and the size and the mass of the electromagnet are greatly reduced relative to the power ratio.

Description

technical field [0001] The invention relates to the field of electromagnets, in particular to a novel electromagnet, a preparation method of the novel electromagnet and a magnetic structure of a loudspeaker. Background technique [0002] An electromagnet is a device that energizes to generate electromagnetism. It winds a conductive winding that matches its power in a concentric circle outside the iron core. Electromagnet is an application of current magnetic effect, which is closely related to life, such as electromagnetic relays, electromagnetic cranes, maglev trains, electronic door locks, intelligent channel turns, electromagnetic flowmeters and other electronic devices. [0003] For some small electronic devices, the current electromagnet will occupy a relatively large space, which limits the miniaturization and ultra-thinning of the small electronic devices. Therefore, how to provide a miniaturized electromagnet to meet the requirements of ultra-thinning or miniaturiza...
