Technical field
The utility model relates to a kind of dynamic iron unit and shell thereof, more particularly, relates to a kind of liquid metal shell of dynamic iron unit and applies the dynamic iron unit of this shell.
Background technology
Dynamic iron unit is the balanced armature up-down vibration by controlling to be arranged in magnetic field, and by conductive bar by this vibration passing to vibrating diaphragm, vibrating diaphragm agitates the air in dynamic iron unit ante-chamber to sound.The dynamic advantages such as iron unit has stable frequency response curve, highly sensitive, high frequency performance is superior and volume is little, therefore adopt the earphone, audio amplifier etc. of dynamic iron unit to enjoy consumers.
Along with dynamic iron unit is in the popularization and application of many special occasions, also more and more higher to the requirement of the properties of dynamic iron unit.On the intensity that the intensity of dynamic iron unit and bearing capacity are mainly reflected in its shell and bearing capacity, the shell of existing dynamic iron unit adopts the metal material with shielding action to make mostly, but because shell wall thickness is very thin, therefore existing chlamydate intensity and bearing capacity can not be satisfactory, and once the shell of dynamic iron unit deforms, cause the decline of dynamic iron unit tonequality after inevitable, what is more, dynamic iron unit internal structure can be caused to damage.In addition, the shell of existing dynamic iron unit is all that employing is stamping forming, and shell precision is not high, and this also has very important impact to the tonequality of dynamic iron unit.
Summary of the invention
1. the utility model technical problem that will solve
The purpose of this utility model is to overcome the poor deficiency of the intensity of existing dynamic iron cell enclosure, bearing capacity and the accuracy of manufacture, a kind of liquid metal shell of dynamic iron unit is provided and applies the dynamic iron unit of this shell, adopt the technical solution of the utility model, utilize the shell of system liquid metal start iron unit, significantly improve intensity and the bearing capacity of dynamic iron cell enclosure, the wall thickness of dynamic iron cell enclosure can be reduced, reduce the overall dimension of dynamic iron unit further; Meanwhile, liquid metal has plasticity ability after melting, can be shaping as plastics, and therefore manufacture craft is more simple, the shell hardness produced and precision high, smooth surface is wear-resisting, has very strong durability and corrosion resistance.
2. technical scheme
For achieving the above object, the technical scheme that the utility model provides is:
The liquid metal shell of a kind of dynamic iron unit of the present utility model, comprise the upper cover and lower cover that are connected in one, described upper cover and lower cover are made up of liquid metal.
Further, described upper cover and lower cover all adopt extrusion process shaping.
Further, described upper cover and lower cover glued joint or are welded in one.
A kind of dynamic iron unit applying above-mentioned liquid metal shell of the present utility model.
3. beneficial effect
The technical scheme adopting the utility model to provide, compared with existing known technology, has following beneficial effect:
The liquid metal shell of a kind of dynamic iron unit of the present utility model and apply the dynamic iron unit of this shell, upper cover and the lower cover of its composition shell are made up of liquid metal, utilize the material characteristic of liquid metal, significantly improve intensity and the bearing capacity of dynamic iron cell enclosure, the wall thickness of dynamic iron cell enclosure can be reduced, reduce the overall dimension of dynamic iron unit further; Meanwhile, liquid metal has plasticity ability after melting, can be shaping as plastics, therefore manufacture craft is more simple, the shell hardness produced and precision high, smooth surface is wear-resisting, there is very strong durability and corrosion resistance, improve the useful life of dynamic iron unit.
Accompanying drawing explanation
Fig. 1 is the structural representation of the liquid metal shell of a kind of dynamic iron unit of the present utility model.
Label declaration in schematic diagram:
1, upper cover; 2, lower cover.
Embodiment
For understanding content of the present utility model further, in conjunction with the accompanying drawings and embodiments the utility model is described in detail.
Embodiment 1
Shown in composition graphs 1, the liquid metal shell of a kind of dynamic iron unit of the present embodiment, comprise the upper cover 1 and lower cover 2 that are connected in one, upper cover 1 and lower cover 2 are made up of liquid metal.Liquid metal is a kind of metal being called the state that can make the transition by California scientific & technical corporation LiquidmetalTechnologies (liquid metal science and technology), it is by zirconium, titanium, nickel, copper, other materials mixing is also had to form, these elements constitute a kind of unique material of antibody Monoclonal, why be referred to as liquid metal, because its fusing point is low, it also has unique non-crystalline molecules structure, there is plasticity ability after melting, its casting process is made more to be similar to plastics instead of metal, the mode of similar blow molding can be adopted, drastically increase Product Precision, and smooth surface is wear-resisting, because the particular molecule attribute of liquid metal, it has the practical characteristic such as high-yield strength, high rigidity, excellent strength-weight ratio, higher elastic limit, anticorrosive and high abrasion, hardness, higher than titanium alloy and steel, has been applied to phone housing and mobile telephone SIM card slot discloses pin etc.Therefore, utilize the shell of system liquid metal start iron unit, significantly improve intensity and the bearing capacity of dynamic iron cell enclosure, the wall thickness of dynamic iron cell enclosure can be reduced, make the shell of iron unit more frivolous, reduce the overall dimension of dynamic iron unit further; Meanwhile, manufacture craft is more simple, the shell hardness produced and precision high, smooth surface is wear-resisting, has very strong durability and corrosion resistance.
The liquid metal shell of a kind of dynamic iron unit of the present embodiment, its upper cover 1 and lower cover 2 all adopt extrusion process shaping, the convenient formation of upper cover 1 and lower cover 2, make precision high, thus also improve the tonequality audio of dynamic iron unit.Upper cover 1 in the present embodiment and lower cover 2 glued joint or are welded in one, easy to assembly, overall solid and reliable.
