Description
Technical field
The utility model relates to a kind of receiver, specifically, relates to a kind of crashproof anti-receiver that falls function that has.
Background technology
Receiver claims again receiver, is a kind of electro-acoustic element that audio electrical signal is converted to voice signal under voiceless sound leak condition, is widely used in the communication terminal devices such as mobile phone, landline telephone, earphone, realizes audio frequency, as the playback of voice and music etc.
But; people usually can cause larger impact to the receiver in these equipment when using the equipment such as mobile phone, landline telephone, earphone in some environment; while being used in ground or in the larger harsh environment of some vibrations as in use accidentally dropped; the impact bringing usually can impact the armature in receiver, thereby causes the receiver cannot trace work.This be because, armature is the important component part of drive unit in receiver, its vibration by self drives the vibrating diaphragm in receiver to vibrate to carry out the transmission of sound, and if armature is subject to larger impact, armature is easy to upwards or downwards to inhale and to die from magnet, thereby cause armature cannot continue vibration and it was lost efficacy, vibrating diaphragm also just cannot continue to vibrate like this, thereby make the whole receiver cannot trace work.
Traditional earphone is for fear of above-mentioned condition, generally adopt and lug boss is set on armature avoids armature and magnet attraction to be integrated, although such setting can reach good effect, because the spacing between magnet and armature is less, its manufacture craft difficulty is higher; And easily making the Oscillation Amplitude of armature reduce, the audiorange of receiver also diminishes thereupon, affects whole acoustical quality.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide the crashproof anti-receiver that falls function that has that a kind of manufacture craft is simple, audiorange is extensive, acoustical quality is good.
For achieving the above object, the technical solution of the utility model is as follows: a kind of have a crashproof anti-receiver that falls function, comprises screening can and be arranged at the moving iron unit in described screening can, and described moving iron unit comprises armature, magnet and coil; Along described armature up-down vibration direction, inner surface relative with described armature on described coil is respectively arranged with at least one lug boss.
Further, the height that described lug boss protrudes from described coil is greater than the distance of described coil inner surface and magnet inner surface.
Further, described lug boss is insulating material.
Further, described armature comprises maincenter, and along the length direction of described maincenter, described lug boss is near described magnet.
Further, along the Width of described maincenter, described lug boss is arranged at the middle part of described maincenter.
Further, described magnet is permanent magnet.
Further, described moving iron unit also comprises iron core, vibrating diaphragm and conductive bar, and described coil and iron core sleeve are located at described maincenter, and described permanent magnet is arranged at the inside of described iron core, and described maincenter is by the described conductive bar described vibrating diaphragm that is in transmission connection.
Adopt technique scheme, the beneficial effect of technical solutions of the utility model is: along armature up-down vibration direction, on coil, the inner surface relative with armature is respectively arranged with at least one lug boss, lug boss is arranged on coil, overcome the little shortcoming in space has been set, spacing between coil and armature is larger, and the manufacture craft of lug boss is simpler; Meanwhile, can not reduce the amplitude of armature, effectively raise the acoustical quality of receiver; Separately, make can effectively prevent that armature is dead by magnet suction in the situation that of greater impact, and then extended useful life.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment 1
As shown in Figure 1, a kind of have a crashproof anti-receiver that falls function, comprises screening can and be arranged at the moving iron unit in screening can, and moving iron unit comprises armature, magnet 1 and coil 2; Along armature up-down vibration direction, on coil 2, the inner surface relative with armature is respectively arranged with a lug boss 3.
The height that lug boss 3 protrudes from coil 2 is greater than the distance of coil 2 inner surfaces and magnet 1 inner surface, and wherein, lug boss 3 is insulating material, is sizing material in the present embodiment.
Armature comprises the flank (scheming not shown) of maincenter 4 and connection maincenter 4, and along the length direction of maincenter 4, lug boss 3 is near magnet 1; Along the Width of maincenter 4, lug boss 3 is arranged at the middle part of maincenter 4.Wherein, magnet 1 is permanent magnet.
