Embodiment Construction

[0014] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments.

[0015] The invention discloses a method for suppressing the opening size of a U-shaped armature, such as figure 1 As shown, the following steps may be included:

[0016] Step S101, designing a tool for limiting the U-shaped armature;

[0017] In this example, if figure 2 As shown, the tool 1 for restraining the U-shaped armature can be made of high-temperature-resistant alumina ceramics, and can be made into a cuboid. Its processing thickness corresponds to the opening size of the U-shaped armature 2, and its tolerance is generally controlled at ...

Abstract

The invention provides a method for inhibiting the opening sizes of U-shaped armatures. The method comprises the following steps: designing a tool for limiting the U-shaped armatures; and respectively inserting a plurality of U-shaped armatures in the tool for limiting the U-shaped armatures, and carrying out a heat treatment. According to the method disclosed by the invention, the tool for limiting the U-shaped armatures is designed, and the plurality of U-shaped armatures are inserted in the tool for limiting U-shaped armatures to carry out the heat treatment so as to ensure the opening size of each U-shaped armature to be consistent with the thickness of the tool for limiting U-shaped armatures, and thus the effect of limiting occurrence of change of the opening sizes of the U-shaped armatures in a high-temperature environment is achieved.

Description

technical field [0001] The invention relates to the technical field of a U-shaped armature of a moving iron horn, in particular to a method for suppressing the opening size of the U-shaped armature. Background technique [0002] Due to the characteristics of small size, low power consumption and high output, moving iron speakers are widely used in hearing aids, covert communication, high-fidelity earphones and other fields, but their assembly process requirements are also very high. As the core component of the U-shaped armature, it is very important to match the size of the two magnets and the iron core. It is very important to ensure the consistency of the opening size of the U-shaped armature for the moving iron horn. However, for the moving iron horn, the iron core, U-shaped armature, and casing basically need heat treatment. Compared with the U-shaped armature, other parts are relatively stable in shape, so there is no need to place the parts during heat treatment. Spe...
