The telephone receiver comprises a shielding outer shell and a moving iron unit arranged in the shielding outer shell. The moving iron unit comprises an armature, magnets and coils. The inside faces, opposite to the armature, of the coils in the vertical vibration direction of the armature are respectively provided with at least a protruding part. The telephone receiver with the anti-collision and anti-throwing function has the anti-collision and anti-throwing function, is simple in manufacturing technology, wide in audio range and better in tone quality effect.
Description
Technical field
The present invention relates to a kind of receiver, specifically, relate 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.
Summary of the invention
For solving the problems of the technologies described above, the object of the present invention 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, technical scheme of the present invention 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.
Further, the manufacture method of described lug boss is as follows:
One, get the raw materials ready: first copper cash, glue and winding former are prepared in advance;
Two, groove processed: the mould bases upper-lower position of winding former is made respectively to corresponding groove;
Three, gluing: coat appropriate glue on the surface of winding former, and make described glue be full of described groove;
Four, coiling: copper cash is wound on described winding former, until complete;
Five, withdrawing pattern: after treating that above-mentioned glue becomes dry, the copper cash that coiling is good takes out, and described copper cash is molded is coil; Meanwhile, the glue in described groove is adhered to the inner surface of described coil, automatically forms lug boss.
Further, the manufacture method of described lug boss is as follows:
One, get the raw materials ready: first copper cash, glue and coil rack are prepared in advance;
Two, groove processed: the roll upper-lower position at coil rack is made respectively corresponding groove;
Three, gluing: coat appropriate glue on the surface of roll, and make described glue be full of described groove;
Four, coiling, moulding: copper cash is wound on described roll, copper cash and the automatic adhesion of glue meeting, the glue in roll groove also can be adhered to the inner surface of coil automatically, forms described lug boss.
Adopt technique scheme, the beneficial effect of technical solution of the present invention 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.
