Problems solved by technology

The existence of this air layer causes the magnetic flux generated by the coil to not completely pass through the armature, but part of the magnetic flux leaks into the air, resulting in a decrease in the receiver's energy conversion efficiency.

Abstract

The invention discloses a magnetic leakage free vertical coil receiver motor. The technical scheme of the invention is as follows: in the magnetic leakage free vertical coil receiver motor, a component comprises a coil, a filler of a high permeability magnetizer, a high permeability concentrating flux plate, an armature, a first magnet, a second magnet and a lower shell (made of a high permeability magnetic material). The coil is provided with a passage, the passage of the coil is arranged to be perpendicular to the inner bottom of the lower shell, the interior of the passage of the coil is filled with high permeability fillers and forms a transverse H-shaped section. There is no gap between the coil and the filler of the high permeability magnetizer, and the magnetic line of force generated by the coil is collected by the high permeability fillers, so that there is no magnetic leakage.

Description

technical field [0001] The invention relates to the technical field of balanced armature type receivers, in particular to a magnetic leakage-free vertical coil receiver motor. Background technique [0002] Because the armature of the motor of the receiver on the market vibrates in the coil passage, there must be an air layer between the coil and the armature. The existence of this air layer causes the magnetic flux generated by the coil to not completely pass through the armature, but part of the magnetic flux leaks into the air, resulting in a decrease in the receiver's energy conversion efficiency. Contents of the invention [0003] In view of the deficiencies in the prior art, the main purpose of the present invention is to provide a vertical coil receiver motor with good structural performance and no magnetic leakage. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a vertical coil receiver motor without ...
