Abstract
The utility model discloses a kind of dynamic iron unit shield shell for loud speaker.A kind of dynamic iron unit shield shell for loud speaker of the present utility model, comprise upper shell and lower house, described upper shell and lower house are " Qian " structure of twice bending, and upper shell and lower house form the accommodation space placing dynamic iron unit to grafting.The utility model processing and easy to assembly, can realize automated production, time saving and energy saving, production efficiency is high.
Description
Technical field
The utility model relates to the shield shell of the phonation unit of a kind of loud speaker, loudspeaker, earphone etc., more particularly, relates to a kind of dynamic iron unit shield shell for loud speaker.
Background technology
Dynamic iron earphone is as mid-to high-end product in the market, in dynamic iron earphone there is critical component for dynamic iron unit in it, it is for moving-coil earphone, frequency response curve is more stable, sensitivity is higher, pleasant dark, the advantage such as resistance is little, focused on gradually the music-lover of tonequality accept pay attention to institute's fan.Dynamic its occurring principle of iron unit is electromagnetic energy conversion, and also namely dynamic iron unit is a sound transducer.By sending sound to solenoid with ac signal pattern, the electromagnetic conductive that solenoid produces balances armature, the magnet being positioned at balanced armature both sides drives balanced armature to move under magneticaction, ac signal has to be had by force weak, then its up-down vibration amplitude of balanced armature is also thereupon different.Balanced armature one end is connected with vibrating diaphragm by wire, and vibrating diaphragm also does corresponding frequencies vibration under the vibration of balanced armature thereupon, thus agitates surrounding air to do corresponding sports, conduction sound.
The shield shell of current dynamic iron unit is divided into lower house and upper cover (shown in Figure 2), and its lower house is identical with the interface physical dimension of upper cover, and interface is plane, by welding or to be gluingly connected and fixed after docking.Because the interface physical dimension of upper-lower casing is identical, and be all plane, when docking, upper-lower casing is difficult to location, does not slightly note causing docking port place position deviation, affects presentation quality.And adopt this structure, upper-lower casing can only adopt metal material, otherwise, cannot weld.And the difficulty of docking port place welding is comparatively large, welding operation required precision is very high, and therefore crudy is difficult to ensure.
Through retrieval, existing technical scheme of carrying out improving for the problems referred to above, as China Patent No. ZL201220441685.X, authorized announcement date is on March 13rd, 2013, invention and created name is: a kind of dynamic iron unit for loudspeaker arrangement, this application case relates to a kind of dynamic iron unit for loudspeaker arrangement, it comprises shield shell, be arranged in the balanced armature of described shield shell, magnet, solenoid, vibrating diaphragm, wire, sound guide tube, described shield shell is divided into upper shell and lower house, and described upper shell and lower house are connected and sealed by nested mode.Upper shell in this application case and lower house are tensioning member, manufacture the mould adopted complicated, also need after punching stretch is complete to carry out secondary operations (truncation, rush side opening, rush the techniques such as side boss), because upper shell and lower house are tensioning member and volume is little, thickness is thin, therefore on upper shell and lower house, carry out secondary operations inconvenience, waste time and energy, production efficiency is low.
