Abstract
An earphone speaker with electrostatic discharge protection, comprising a loudspeaker unit, a metal mesh cover and a flexible conductive piece. The loudspeaker unit comprises an input for receiving voice signals and the input is provided with a positive contact and a negative contact. The metal mesh cover is covered on the loudspeaker component for protecting the loudspeaker mouth. The flexible conductive piece is provided with a first end fixed and connected with the negative contact and a second end that is opposite to the first end and that is connected against the metal mesh cover, when the metal mesh cover accumulates static electricity, the flexible conductive piece can lead static electricity to the grounding by the negative contact, thus achieving the electrostatic discharge protection function.
Description
Technical field
The utility model relates to a kind of earphone horn, particularly relates to a kind of earphone horn with electrostatic discharge (ESD) protection.
Background technology
Consult Fig. 1; the general earphone horn that uses enters loud speaker 41 for preventing foreign matter; usually can use metal guard 42 to cover in loud speaker 41 peripheries not destroyed by foreign matter with protection loud speaker 41; but; metal guard 42 is easily accumulated static usually and is produced electrostatic effect; electrostatic effect not only can spread in airborne floating dust or particulate in the absorption of metal guard 42 outsides; and then influence the view quality of earphone horn; even if health and earphone horn have potential difference; this moment, human body was as the contact earphone horn; will be to earphone horn discharge generation surging, that is so-called static discharge (Electrostatic Discharge, ESD).And static discharge is to cause most electronic building brick or electronic system to be subjected to excessively electrically stress (Electrical Overstress, EOS) principal element of Po Huaiing, this destruction will make with earphone horn in loud speaker and audifier work undesired, even cause the earphone horn spoilage to increase.
Summary of the invention
Therefore, the purpose of this utility model is to provide a kind of earphone horn with electrostatic discharge (ESD) protection, destroys by avoiding static discharge, improves its useful life.
So the earphone horn that the utlity model has electrostatic discharge (ESD) protection mainly comprises a speaker unit, a metal guard, and a flexible conducting spare.This speaker unit comprises that one is used to receive the input of sound signal, and a mouth of raising one's voice that is used for the output sound signal, and this input has a positive contact and a negative contact.This metal guard cover is overlying on this member of raising one's voice, and is used to protect this mouth of raising one's voice.This flexible conducting spare have one with should negative first affixed end of contact, and one in contrast to this first end and second end that connects with this metal guard.
Description of drawings
Fig. 1 is the rearview of known technology;
Fig. 2 is the rearview of preferred embodiment of the present utility model;
Fig. 3 is the cutaway view of preferred embodiment assembly relation of the present utility model.
Embodiment
Consult Fig. 2, Fig. 3, the preferred embodiment that the utlity model has the earphone horn of electrostatic discharge (ESD) protection is to be installed in the earphone (figure does not show), and comprises a speaker unit 1, a metal guard 2, and a flexible conducting spare 3.What deserves to be mentioned is at this, is with monolateral earphone horn representative explanation in the present embodiment, so has the knack of this operator can understand easily that can also be used in bilateral earphone horn, there is no can not.
This speaker unit 1 comprises the loud speaker 11 of a corresponding human body ear, and one forms the lead 12 that is electrically connected with the transmission sound signal with this loud speaker 11.This loud speaker 11 comprises that a body 111, is positioned at these body 111 rear ends (promptly figure's is right-hand) and is used to receive the input 112 of sound signal, and one be positioned at these body 111 front ends (i.e. the left of figure) and be used for the output sound signal raise one's voice mouthfuls 113.Wherein, this input 112 has a negative contact 114 and a positive contact 115.In the present embodiment, because this loud speaker 11 is known and mature technology, do not repeat them here.In the present embodiment, be that this lead 12 is welded in this input 112, be electrically connected by fixing and formation.
This metal guard 2 is to cover at this speaker unit 1 one sides, and coats this loud speaker 11 front ends, is used to avoid external foreign matter to invade the destruction of causing this speaker unit 1.This metal guard 2 has majority and runs through the sender 21 that forms inwardly by these metal guard 2 outer surfaces, is used for spreading out of for sound signal.
In the present embodiment, this flexible conducting spare 3 can be metal clips or copper foil.This flexible conducting spare 3 have one with should be negative the first affixed end 31 of contact 114, and one in contrast to this first end 31 and second end 32 that connects with this metal guard 2.In the present embodiment, be that this flexible conducting spare 3 is fixedly welded on this negative contact 114, again lead 12 is welded in the negative contact 114 and positive contact 115 of this input 112, right welding is fixing also only to be a kind of in numerous execution modes, be not to be restrictive condition of the present utility model, as long as make this flexible conducting spare 3 with respect to the fixing relative position of this negative contact 114.
Conclude above-mentionedly, make electrostatic current through should negative contact 114 and then derive ground connection, not only can avoid static discharge to destroy earphone horn, more can improve the life of product of earphone horn, and reach the purpose of this utility model really by this flexible conducting spare 3.
Claims (3)
