Description

The crashproof anti-type receiver that falls
Technical field
The present invention relates to a kind of receiver, particularly a kind of crashproof anti-type receiver that falls.
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 in the time using the equipment such as mobile phone, landline telephone, earphone in some environment; while use 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, if and 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 makes the whole receiver cannot trace work.
Therefore, under greater impact, also can effectively prevent that armature from being inhaled dead receiver by magnet if can provide a kind of, so just can reduce the loss percentage of receiver under this environment, and then extend the service life of receiver.
Summary of the invention
