Description

Earphone In / Out Device for Mobile Phones {INSTRUMENT FOR ROLLING EARPHONE WIRE}

The present invention relates to an earphone in and out device for use in a mobile terminal.

In general, as the size of a communication or listening device such as a mobile phone, a portable mini cassette, an MP3 player, and a radio becomes smaller, a portable necklace and a portable necklace that can be carried around the neck by connecting the electronic devices for easy carrying Necklace-type ear microphones for electrically connecting and communicating with each other are widely used.

The ear microphones are kept in the neck after use or left without a separate storage means, and this neglect causes damage and entanglement of the ear microphones.

In addition, since the earphone is separated from the portable terminal main body and the earphone in a separate state, it has to be always provided with each other when used, and has to be moved together when moving.

In addition, the earphone has a disadvantage of being very inconvenient when using the earphone because the earphone should be connected to the terminal body to find a separate earphone during the call of the mobile terminal.

In addition, since the earphone is exposed to the outside, it may be damaged by external impact or contact during use and storage, and may be stored in an unorganized state, resulting in deterioration or poor appearance.

The present invention has been made to solve the above problems of the prior art, an object of the present invention is easy to pull in and out of the earphone in the mobile terminal while the introduction of the earphone for the mobile terminal can minimize the amount of impact due to automatic insertion And a drawing device.

In order to achieve the above and other objects,

An earphone jack, a microphone, and an earphone part connected to the portable terminal are sequentially provided, and a microphone side enlarged part is provided in the microphone, the diameter of which gradually increases from the earphone jack toward the microphone, and the earphone jack and the microphone are provided. An earphone for a mobile terminal, wherein an earphone side enlargement and reduction alternate portion is provided between the side enlargement portion and the diameter gradually increases and decreases; And

An earphone insertion and withdrawal mechanism for entering and withdrawing the earphone for the portable terminal, comprising: a case; A bobbin rotatably provided on opposite sides of the case, and the earphone wound around a circumferential surface thereof; An earphone jack fixture formed on one side of the case to help fix the earphone jack; Earphone draw-out hole formed on the other side of the case; A pair of elastic rollers disposed inside the case and rotatably provided on opposite sides of the case to rotate by mutual frictional contact; And an earphone inlet / outlet mechanism including a spring in which one side contacts one of the pair of elastic rollers and the other side contacts the inner surface of the case.

In the pair of elastic rollers, grooves corresponding to the average diameter of the string of the earphone are formed on the circumferential surfaces of the pair of elastic rollers with respect to the circumferential surfaces of the pair of elastic rollers, and the springs 44 are in contact with each other. Both ends of the roller side operate separately from the roller, and the roller in contact with the spring provides an earphone inlet and outlet device for a mobile terminal, characterized in that the shaft is configured to be movable.

The earphone insertion and withdrawal device for the mobile terminal according to the present invention can reduce the entry speed of the earphone due to the combination configuration of the pair of rollers and the incremental diameter portion provided in the earphone when the earphone is automatically inserted. This enables the long-term use of the earphone by minimizing the amount of noise. In addition, since the device according to the present invention is stored in a state wound inside when not using the earphone can be prevented twisting and damage due to the twisting of the earphone.

As an example of use, it is a diagram illustrating a state in which earphones are drawn out, and FIG. 6 is a diagram illustrating a state in which the earphones are decelerated while being drawn in as an example of use of the earphone insertion and withdrawal device for a mobile terminal according to the present invention.

Referring to these drawings, the earphone input and withdrawal device for a mobile terminal according to the present invention includes both the earphone configuration and earphone input and withdrawal configuration.

The earphone 10 used in the present invention includes an earphone jack 12, a microphone 14, and an earphone part 16 connected to a portable terminal as is commonly used. However, in the present invention, the microphone-side enlarged portion 14 'and the earphone jack 12 and the microphone-side enlarged portion 14 of which the diameter increases gradually toward the microphone 14 to the microphone 14 in the earphone 10 ( 14 ') further includes an earphone-side enlarged and reduced alternating portion 16 in which the diameter gradually increases and decreases. Such a configuration is an essential configuration in some cases in the present invention, and the structural necessity for this portion will be described later.

In the present invention, the configuration of the earphone 10 and the structure of the earphone 10 in addition and withdrawal (in the present invention, the earphone insertion and withdrawal mechanism 30) is essentially further included.

The earphone retracting and withdrawing mechanism 30 has a structure in which the whole is fixed by fitting the earphone jack 12 to one side of the portable terminal, for example, as shown in FIG. 1.

This earphone retracting and withdrawing mechanism 30 is provided rotatably with respect to the case 32, opposite sides of the case 32, as shown in Figure 1 and in particular Figures 2 to 4 The bobbin 34 on which the earphone 10 is wound, the earphone jack fixture 36 formed on one side of the case 32 to help fix the earphone jack 12, and formed on the other side of the case 32. A pair of earphone inlet / outlet 36 '(refer to FIG. 1), which is disposed inside the case 32, is rotatably provided on opposite sides of the case 32, and rotates by mutual frictional contact. One side of the elastic roller 40 and one of the pair of elastic rollers 40 includes a spring 44 which is in contact with the inner surface of the case 32.

More specifically, the pair of rollers 40 has a groove corresponding to the average diameter of the string of the earphone 10 on the circumferential surface in frictional contact with each other, as shown in these figures. Both ends of the roller side which are formed together with respect to the main surface and which contact the spring 44 operate separately from the roller 40, and the roller 40 which contacts the spring 44 is capable of axial movement. It is composed.

Hereinafter, the withdrawal process and withdrawal process of the earphone will be described with reference to FIGS. 5 and 6.

Referring to Figure 5, the user is pulling the earphone from the earphone inlet and withdrawal device according to the present invention detachably coupled to the portable terminal. When pulled to some extent, the expansion and contraction alternating portions provided on the earphone jack side pass through the pair of rollers. At this time, the roller located in the upper portion of the drawing of the pair of rollers to move the shaft, and is restored to the original position by the spring again. After this process, the earphones remain withdrawn.

Meanwhile, referring to FIG. 6, the user moves the roller as described above after using the earphone, and while the earphone is retracted, the roller is in contact with the enlarged portion provided on the microphone side, and the enlarged portion and the elasticity of the roller are Due to the frictional contact with the part, the entry speed of the earphone is drastically reduced. That is, the pulling speed of the earphone is reduced by the buffering action by the elastic roller. Moreover, a pair of guide grooves are provided on the circumferential surface of the roller to assist and guide such deceleration.
