Description

[0001] EARPHONES ADJUSTABLE SIZE FOR EAR CANAL ADAPTATION [0002]

The present invention relates to a ear-tunable ear-adaptive earphone, and more particularly, it relates to an ear-ear-adjustable earphone which can be adjusted in size according to a user's ear kernels using an earphone and can prevent pain from being used for a long time, And an earphone adaptive earphone that can be sized to prevent breakage and reduce manufacturing costs.

Recently, with the development of information and communication technology, music listening functions provided in portable audio players such as portable sound players and MP3 are also provided in mobile communication portable terminals such as smart phones, and thus, Various efforts have been made to improve the audio quality of earphones which are widely used.

In order to enhance the audio quality of the conventional earphone, there has been a technique of inserting a wearing portion of a kernel into the ear keeper of a user so as to be in contact with the inner face of the ear keeper to hear the sound more closely.

However, if the portion to be inserted into the kernel is made of a hard synthetic resin when the portion to be worn by the kernel is directly inserted into the inner portion of the core, there is a problem that it can cause pain when used for a long time.

In addition, since most of the ear kernels are manufactured in the same size, there is a gap in the contact point inside the ear kernels due to the size of the ear kernels according to each user, so that it is difficult to prevent noise from the outside, There is a problem that the earphone is frequently detached when the user is in an environment of exercise.

In order to solve such a problem, as a conventional art, there is known a method of adjusting the size of a deformed tube to a size of a user's ears by compressing air by using a pumping button which forms a wear part with a tube whose shape is varied by air and receives an external force from the rear surface of the wear part There was a technique to adjust accordingly.

However, since the size of the deformable tube is controlled by compressing the air by the conventional pumping button, the size of the deformable tube is adjusted by using the air. Therefore, when the deformable tube is shrunk for a certain period of time after wearing, There is a problem in that when the pump is used for a long time, malfunction occurs, or if an external force equal to or greater than a certain magnitude is applied, the pump is broken, the internal structure is complicated, and the manufacturing cost is increased .

Therefore, it is possible to prevent the pain from being generated even when using for a long time, to effectively prevent noise from the outside, to prevent deterioration of audio quality, to prevent the earphone from being detached even when worn for a long time, There is an urgent need for realistic and highly utilizable technologies that can prevent defects or damage and reduce manufacturing costs.
