The present invention relates to a general-purpose ear jack plug device, and more particularly, to the ear jack plug device of an earphone or a headset used by connecting to a mobile device or an audio device such as an audio or cassette player, an acoustic signal (R signal and L signal). The present invention relates to a universal earjack plug device having four poles for transmitting / receiving both a microphone signal and a ground signal to be compatible with a mobile communication terminal and various audio devices.

Recently, when using a mobile communication terminal, the headset uses an integrated headset and microphone so that both hands can use the phone freely. These headsets do not have to make a loud sound when using the mobile terminal. In particular, since the use of both hands freely to talk while driving the vehicle, the use is increasing.

The headset is electrically connected by inserting an ear jack plug provided at one end thereof into a connector hole drilled at one side of the mobile communication terminal so that a call can be made while transmitting and receiving signals with each other.

The other side is provided with a connection part 6 connected through the inside of the contact part 3 to transfer the signal to an earphone (not shown) or a microphone (not shown) and a clamp 7 for controlling the connection parts 6. It is surrounded by a predetermined sheath (not shown). In the figure, a state in which the coating is peeled off on the connection part 7 side is shown.

When the ear jack plug 1 is tightly coupled to the connecting hole, the holder 5 is caught by the connecting hole inlet 9 so that the sleeve 13 is in close contact with the sleeve terminal 13 '. It allows you to stay connected to each other.

In addition, the contact portion 3 is separated into three poles through a divider 8, one end portion of which is responsible for a microphone signal (11), the middle portion is responsible for the ear (ring) ( 12), one side of the middle portion is composed of a sleeve portion 13 of the ground (GND), respectively.

In addition, there is a respective contact terminal portion 4a in close contact with the contact portion 3 inside the connector hole of the mobile communication terminal. The innermost side of the microphone terminal portion 11 'corresponding to the tip portion 11 and the outermost side are grounded. The terminal portion 13 'and the middle portion are provided with ear terminal portions 12'.

Therefore, while the contact portion 3 of the ear jack plug 1 is inserted into the connecting hole, the tip portion 11 of the contact portion 3 is in contact with the microphone terminal portion 11 'to perform a voice transmission function. The ring part 12 contacts the ear terminal part 12 'to receive a voice or sound, and the sleeve part 13 is brought into close contact with the ground terminal part 13' to be in an electrical connection state. It exchanges signals and ground signals, and enables communication of mobile communication terminals.

On the other hand, in a similar structure, the ear jack plug 2 used in a stereo audio device such as a cassette player, CD player, audio, etc. is shown in FIG. 1B.

The ear jack plug 2 used in such an acoustic device also has the same appearance as the ear jack plug 1 for the mobile communication terminal described above, but the tip portion 21 of one end of the contact portion 3 has an L signal (left or hot). The ring portion 22 is responsible for the R signal (Right or cold), one side of the ring portion 22 is provided with a sleeve portion 23 of the ground (GND).

In addition, the L signal terminal 21 ', the R signal terminal 22', and the ground terminal 23 'are formed at a position corresponding to the contact portion 3 at the connecting hole side.

As described above, the ear jack plug 2 of the acoustic device and the ear jack plug 1 of the mobile communication terminal have the same three poles, but the roles of the respective contact parts 3 are different, so that they are compatible with each other. It was impossible.

Therefore, it is economically wasteful to purchase and use an ear jack or headset for a mobile communication terminal separately from the earphone for an audio device, and also has to carry each earphone or headset when carrying the audio device and the mobile terminal together. The inconvenience was great.

Therefore, the present invention was developed in view of the above-mentioned conventional problems, and an object of the present invention is to provide an ear jack plug of an earphone or a headset that is compatible with a mobile communication terminal and various audio devices.
