Anti-mechanical shock armature device used for moving-iron receiver/ speaker

Abstract

The invention discloses an anti-mechanical shock armature device with an innovated structure used for a moving-iron receiver/ speaker. The anti-mechanical shock armature device comprises a vibration energy changing part, an anti-mechanical shock device and magnetic conduction connection parts, and is characterized in that the vibration energy changing part which is of a planar structure is arranged in the middle, the protruding and concave-shaped anti-mechanical shock device which is directly crossed with the planar structure is distributed on the vibration energy changing part, and the vibration energy changing part is further connected with the magnetic conduction connection parts arranged on the two sides and tail portion to form the armature device. Compared with a traditional armature device, the anti-mechanical shock armature device has at least the advantages that the anti-mechanical shock device is additionally arranged to the vibration energy changing part in an innovated mode, the mechanical shock resistance property of the moving-iron receiver/ speaker using the armature device is greatly improved, manufacturability is strong, cost is low, and packaging technology is simple and convenient in the subsequent manufacturing process of the receiver/ speaker. In addition, the anti-mechanical shock device can also be applied to various armature devices conveniently, and a marketing value is large.

Description

technical field [0001] The invention relates to an energy conversion and vibration generating device, in particular to an anti-mechanical shock armature device applied in a miniature moving iron receiver / speaker, belonging to the fields of electroacoustics and micromechanics. Background technique [0002] At present, armature devices for moving iron receivers / speakers in the market generally adopt three types: "U", "E" or flat. These three common armature devices do not have any additional mechanical resistance. Impact device, at the same time, because of the limitations of the materials used and the characteristics of the mechanical structure, the existing armature device generally has the disadvantage of insufficient structural rigidity, and thus the moving iron receiver / speaker generally has poor mechanical impact resistance. One drawback. In order to improve the mechanical shock resistance of the moving iron receiver / speaker, in existing products, it is usually necessar...

Problems solved by technology

[0002] The armature devices for moving iron receivers / speakers currently on the market generally adopt three types: "U", "E" or flat. These three common armature devices do not have any additional mechanical resistance. Impact device, at the same time, because of the limitations of the materials used and the characteristics of the mechanical structure, the existing armature device generally has the disadvantage of insufficient structural rigidity, which also results in the generally poor mechanical impact resistance of the moving iron receiver / speaker. a malady

In order to improve the mechanical shock resistance of the moving iron receiver / speaker, in existing products, it is usually necessary to add an anti-mechanical shock device to the inner hole wall of the magnetic induction coil or the surface of the magnetic sheet, which not only increases the material cost and manufacturing cost, but also, Because the process of adding these anti-mechanical shock devices is relatively complicated, the mechanical shock resistance of related receiver / speaker products often does not achieve the desired effect
