Abstract

The utility model provides an earplug sleeve of an in-ear earphone. The earplug sleeve comprises an earphone body, an earplug sleeve joint portion, and a truncated cone earplug sleeve made from a slow rebound material. One end of the truncated cone of the earplug sleeve is equipped with an inclined eccentric boss. A transverse plane of the inclined eccentric boss of the earplug sleeve is provided with a groove that is jointed with the earphone body. One end of the truncated cone earplug sleeve, inserted into an ear, is a semispherical round joint. An elastic rubber sleeve may be sleeved between the earplug sleeve joint portion and the earplug sleeve. The structure of the earplug sleeve of the in-ear earphone well accords with structural characteristics of ear canals of a human body. When a user is using the in-ear earphone for listening, the user inserts the earphone equipped with the earplug sleeve into one ear canal to make the inclined eccentric boss of the earplug sleeve adhere to the auricle of the user, thereby effectively preventing the earplug sleeve from being completely inserted into the ear canal. The in-ear earphone according with structural characteristics of the ear canals of the human body is comfortable to wear and safe to use. A dual sound insulation design formed by the truncated cone and the boss of the earplug sleeve helps to improve a sound insulation effect of the earphone so that the earphone exhibits better timbre.

Description

A kind of earplug cover of In-Ear Headphones

Technical field

The utility model relates to a kind of earphone unit, is specifically related to a kind of earplug cover of In-Ear Headphones.

Background technology

Existing earphone generally is divided into two kinds, and a kind of is the earphone that is connected with head hoop, also has a kind of for having the In-Ear Headphones that earplug is directly filled in auricle.Usually the earplug of In-Ear Headphones adopts the sponge kind material to process, and sponge density is little, and soundproof effect is poor.The inventor adopts slow rebound polyurethane material earplug for this reason, has invented the patent of " earplug of In-Ear Headphones (ZL200720176096.2) ", and is as shown in Figure 1, the soundproof effect of earphone is improved, and wears pleasant.Owing to use the earplug cover of slow rebound polyurethane material to be cylinder or circular cone stage body; Directly earplug is enclosed within the earplug socket part of earphone; In-Ear Headphones is filled in contact with the human body auricle behind the duct tightr, still, and when need not be when ear be taken earphone; The earplug cover of earphone comes off from the earphone earplug socket part sometimes and stays the duct, makes troubles to use.

The utility model content

The purpose of the utility model provides a kind of earplug cover of In-Ear Headphones; The earplug cover that is enclosed within on the In-Ear Headphones is provided with the eccentric boss that tilts; Effectively stoped the earplug cover to be filled in fully in the duct; Both guaranteed safe in utilizationly, the soundproof effect that has improved has again solved the problems referred to above that existing In-Ear Headphones earplug cover exists.

The technical scheme that the utility model adopted is; A kind of earplug cover of In-Ear Headphones; Comprise earphone body, earplug cover socket part, and the circular cone stage body earplug cover of being made by slow resilient material, an end of said earplug cover circular cone stage body is provided with the eccentric boss that tilts; Be provided with the groove with the socket of earphone body in the end face of earplug cover obliquity prominence platform, the pleasant end of circular cone stage body earplug cover connects for the hemisphere circle.

The earplug cover of the described In-Ear Headphones of the utility model, its characteristic also be,

Between said earplug cover socket part and earplug cover, be with one section elastic rubber sleeve.

The earplug cover of the utility model In-Ear Headphones; The earplug cover end that it will be enclosed within on the In-Ear Headphones is provided with the eccentric boss of an inclination, and the earplug cover is filled in duct during use, and the eccentric boss of earplug cover inclination is affixed on auricle; Stoped the earplug cover to be filled in fully in the duct; Not only guaranteed the comfortable and safe use of wearing of In-Ear Headphones, the dual sound Insulation Design that the circular cone stage body of earplug cover and boss form has improved the soundproof effect of insert earphone, makes tonequality better.

Among the figure, 1. earphone body, 2. earplug cover socket part, 3. earplug cover, 4. boss, 5. groove, 6. hemisphere, 7. elastic rubber sleeve, 8. earplug passage, 9 ducts.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.

A kind of earplug cover of In-Ear Headphones; As shown in Figures 2 and 3,1, a kind of earplug cover of In-Ear Headphones, comprise earphone body 1, earplug cover socket part 2; And the circular cone stage body earplug cover of making by slow resilient material 3; The end that said earplug overlaps 3 circular cone stage bodies is provided with the eccentric boss 4 that tilts, and the end face that overlaps 3 obliquity prominence platforms 4 in earplug is provided with the groove 5 with 1 socket of earphone body, and it is that hemisphere 6 circles connect that circular cone stage body earplug overlaps 3 pleasant ends.

The earplug cover of the utility model In-Ear Headphones; The circular cone stage body earplug cover 3 that is sleeved on earplug cover socket part 2 leans on earphone body 1 one ends to be set to have the eccentric boss 4 of an inclination; The end face that earplug overlaps 3 obliquity prominence platforms 4 is provided with the groove 5 with 1 socket of earphone body, this earplug cover 3 is enclosed within earphone body 1 goes into duct with earplug cover socket part 2 top plugs and be used to listen to.

The earplug nested structure of the utility model In-Ear Headphones meets the human antrum auris architectural feature very much, and earplug cover 3 is filled in duct during use, and is as shown in Figure 4; The boss 4 that earplug cover 3 tilts off-centre is close to auricle; Make earplug cover 3 can not all fill in duct 9, and soundproof effect is good, because the PU material of slow resilient material for forming of earplug cover 3 by PPG and isocyanate reaction chain extension interlinkage; It is the hemisphere that connects with circular cone stage body circle that the circular cone stage body earplug of slow resilience PU material overlaps 3 pleasant ends; The earplug passage 8 of earphone directly communicates with the duct 9 of ear, and is more comfortable after filling in, and can not injure duct 9.
