Description

Earphones with Shrink and Expanding Members {EAR PHONE}

This proposal relates to earphones used in connection with various acoustic devices and communication equipment. In particular, by combining the contraction and expansion member formed with the sound guide hole to the outside of the speaker coupled to the case of the earphone, it fits the size of the ear hole of the user It is possible to wear and prevent the detachment of the earphone from the ear canal naturally by custom-wearing, and get soundproofing effect close to perfection, and the contraction / expansion member that can use the earphone for a long time by the comfort of custom-wearing. It is about the earphone attached.

Conventionally, the configuration of earphones used in connection with various acoustic devices and communication equipment is configured to include a speaker connected to an electric wire inside the case.

In addition, some earphones are coupled to the outside of the speaker sponge.

The conventional earphone as described above is not worn by inserting into the ear hole, but is worn at the ear hole entrance.

Therefore, since the earphone is not firmly worn, there are many phenomena of natural detachment from the ear hole entrance, and the earphone has to be frequently pressed toward the ear hole.

In addition, since the size of the wearer's ear hole is different depending on the people, there is no earphone that fits the size of the wearer's ear hole.

Therefore, the conventional earphone has a problem that external noise is transmitted to the ear hole together with the sound of the speaker because the sound insulation effect is not perfect.

In addition, due to the problems described above, there was also a problem that can not be used for a long time.

The purpose of this article to solve and complement these conventional problems,

It can be customized to fit the size of the ear hole of the user, and it can prevent the earphone from being naturally removed from the ear hole. Serve the purpose of making it available for

In order to achieve the above object,

When combined with the contraction, expansion member formed with a sound guide hole to the outside of the speaker coupled to the case of the earphone can achieve the purpose of the present proposal.

101-case 102-speakers

103-Wire 104-Shrink, Expanding Member

105-sound guide

The configuration of the present invention will be described in detail with reference to the accompanying drawings.

The outer side of the speaker 102 coupled to the case 101 of the earphone is configured to combine the contraction, expansion member 104, the sound guide hole 105 is formed.

The operation of this paper is as follows.

First, the outer part of the speaker 102 coupled to the case 101 of the earpiece earphone is coupled to the contraction, expansion member 104 is formed with an acoustic guide hole 105, the contraction, expansion member 104 As shown in Fig. 1, the initial shape of the contraction and expansion member 104 is maintained in an expanded state, so that the sound guide hole 105 is also maintained in an expanded state.

As described above, when the wearer contracts by hand and presses the expansion member 104 in a state in which the contraction and expansion member 104 is coupled to the earphone as described above, the contraction and expansion member 104 contracts as shown in FIG. .

At this time, the contraction of the contracted and thinned state, the expansion member 104 can be inserted smoothly into the wearer's ear hole.

As described above, the contraction and expansion member 104 inserted into the wearer's ear hole gradually starts the expansion operation to return to the original position.

In addition, the contraction and expansion member 104 expands to fit the size of the wearer's ear hole after about 1-2 minutes, and the expansion force of the contraction and expansion member 104 is continuously elastic to the inner circumferential surfaces of the ear hole. Will be supported.

Therefore, the contraction and expansion member 104 is not naturally detached from the ear hole, and the soundproofing effect can be obtained close to perfection, and the earphone can be used for a long time by the comfort by fitting.

In addition, when the earphone is separated from the ear hole, it is possible to easily remove the contraction and expansion member 104 from the ear hole by pulling the case 101 of the earphone as in the prior art.

In addition, the contraction and expansion member 104 removed from the ear hole by the wearer's intention starts to expand continuously and is returned to its initial form as shown in FIG.

In this way, by combining the contraction, expansion member formed with the sound guide hole to the outer portion of the speaker coupled to the case of the earphone, it is possible to fit the fit to the size of the ear hole of the user and the earphone to the ear hole by the custom wearing It can be prevented from being removed from nature and can get soundproofing effect close to perfection and has the useful effect that earphone can be used for a long time by the comfort by custom wearing.

Claims (1)

Earphones with a contraction, expansion member is characterized in that coupled to the outer portion of the speaker 102 is coupled to the case 101 of the earphone, the sound guide hole 105 is formed, the contraction, expansion member (104).
