Module Compared, to a earphone.

A mobile phone, a necessity of modern people, is a mobile phone that is always carried by the user indoors and outdoors or in public places, and has been spotlighted by modern people for its portability and simplicity that users can always carry and talk indoors and outdoors. As the mobile communication system is developed, it has been developed from the mobile communication terminal of the simple call function to the camera phone for message transmission including the picture and video as the PC and the mobile device, and the communication, the computer, It is changing to a terminal with a complex function which can use AV function smoothly.

The mobile terminal of the above-described complex function is generally connected to a large memory (nonvolatile flash memory, etc.) and a memory capable of downloading and storing a large amount of digital information, and recording information by embedding an operation program using a predetermined protocol. The controller stores and outputs the information of various contents by controlling and controlling the device. However, since the internal memory capacity of the terminal is limited, the contents of the contents are sufficient to satisfy various needs of the user. In order to have a separate external memory as a portable storage device in addition to the internal memory in the mobile phone is not cumbersome and economical, in particular, there is a problem in that the data of an external digital device can not be directly used without a PC.

Therefore, an earphone jack connected to an earphone jack such as a mobile phone is usually formed at one end of a connection line having a predetermined length, and a receiver (receiver) for converting an electrical voice signal to a sound is formed at the other end. There is a problem in that the earphone or the simple listening function for transmitting and receiving a signal cannot directly use a PC or an external memory without a USB cable connected to a USB port of a general computer such as a PC to perform a USB communication.

As a result, in order to use digital data of various contents by using earphones, a separate external memory is required in addition to the earphones, and a data cable equipped with a USB communication connection terminal is required as a means of connecting and transferring data. There was this uncomfortable and uneconomical problem.

In order to solve the above problems, as shown in FIG. 6, there is an extension function interface device that can be connected to the earphone socket of the mobile phone and can be detachably contacted with the earphone, but it must have a separate external memory card reader. Therefore, it was troublesome, uneconomical, and there was a problem in that it could not be connected to the communication port of the mobile phone.

In addition, in order to achieve success commercially for the new generation with sensitivity sensitive to fashion, it is applied to electronic products such as mobile phones, which are becoming smaller and lighter and more versatile, to realize the beautiful decorative effect that combines personality and fashion. Beyond the role of simple accessories, products with more practical and diversified design are required.

The present invention has been made to solve the above-mentioned problems, in order to configure a memory expansion device using a communication port of an electronic product such as a mobile phone by attaching a detachable small and lightweight memory expansion module having a USB port for data communication in earphones As well as a PC or laptop to which USB is generally applied, as a mobile communication device, a mobile phone equipped with a USB communication port and a portable storage device can be connected to an external memory card and used as an earphone function for voice communication and a digital data communication function with a computer. Design features beautiful functions such as memory card reader function, memory function of data storage, and decoration effect, and it is an integrated device with integrated functions, so it can be realized as one integrated device with good economical efficiency. Digital has greatly improved Emitter is aimed to provide an earphone device having a communication memory expansion module.
