Description

[0001] The present invention relates to a Bluetooth-earphone available for wired type,

More particularly, the present invention relates to a Bluetooth earphone capable of charging a user device for use with a Bluetooth earphone and a Bluetooth earphone, In addition, when the battery of the Bluetooth earphone is discharged, the Bluetooth earphone is connected to the user terminal by wire to receive the electric power from the user terminal in an urgent manner and to receive the digital audio signal from the user terminal and receive the sound. And a user terminal having an effect of charging the wireless terminal.

The Bluetooth headset performs data communication with a user terminal (e.g., smart phone, MP3, tablet PC, notebook, etc.) using a Bluetooth module, acquires audio information transmitted from the user terminal through the Bluetooth module, And outputs the information to the user.

As 4G LTE (4th generation Long Term Evolution) is implemented due to the development of communication technology, various contents can be viewed through wireless communication using a smart phone or a tablet PC, Terminal and a wired earphone that outputs sound through earphone, the preference of a headset or an earphone equipped with a Bluetooth function is gradually increasing.

Bluetooth is a short-range wireless technology standard that exchanges information by connecting mobile devices such as mobile phones, laptops, earphones, and headphones. It is used when a low-power wireless connection is required in very short distances, typically about 10 meters.

[0003] As communication technology has developed as described above, various types of headsets or earphones have been developed using Bluetooth, and such technologies include Patent Documents 1 to 3.

Patent Document 1 discloses a case having a plurality of function buttons for sound reproduction and communication and a case having a connection plug connected to an earphone connection groove of the mobile terminal and receiving a signal related to output of various sounds or a call from the mobile terminal by wire, A master Bluetooth module for Bluetooth communication, a control unit for controlling the operation of the master Bluetooth module according to the selection of the function buttons, and a control unit for controlling the operation of the master Bluetooth module. The earphone main body is detachably mounted on the earphone main body, And a unit earphone having a slave Bluetooth module paired to enable Bluetooth communication with the master Bluetooth module of the slave Bluetooth module and an output unit outputting sound data received through the slave Bluetooth module, And the earphone The master Bluetooth module is set to be paired so as to be able to communicate simultaneously with the slave Bluetooth modules of the two unit earphones, a mounting groove is formed on the outer surface of the earphone body, and the unit earphone is mounted on the mounting groove Wherein the earphone main body further comprises a microphone for receiving voice when used for a communication purpose and the earphone main body is formed to have an animal shape or a human figure or a shape of a specific character, The unit earphone is mounted on the circumferential surface of the earphone main body and is formed so as to have the shape of an animal, a person or an ear of a specific character shaped by the earphone main body. The unit earphone includes various data through Bluetooth communication with the mobile terminal And a transmitting / receiving unit The earphone main body and each unit earphone are connected to each other by a wired connection with the mobile terminal so that sound output can be performed while they are communicating with each other through Bluetooth communication. In addition, the earphone main body and each unit earphone are always set to be paired Therefore, it is possible to solve the inconvenience of the user performing a manual operation for connecting the mobile terminal and the multifunctional earphone of the present invention by Bluetooth communication,

Patent Document 2 discloses a microphone device having a body of a predetermined shape, a speaker device installed in the above place, a microphone device installed on the body so as to be separated from the speaker device by a predetermined distance, And a USB connector for selectively extending / inflating the ear hook and an USB connector for electrically connecting to the USB port of the PC and transmitting / receiving data to / from the terminal, In addition to the call, the built-in USB contactor is used as a wireless adapter for data transmission and reception by directly connecting with a PC. Therefore, it is advantageous in that it is not necessary to use a separate data cable or adapter,

Patent Document 3 discloses a Bluetooth built-in wireless earphone including a control body having a printed circuit board including a microphone connected to one earphone line of the earphone head and an adjustment button, and a Bluetooth module installed at the center of both earphone lines, And the earphone line is inserted into the fitting portion of the neckband which is formed by being closed and the other side is closed. The neckband and the Bluetooth built-in wireless earphone are mutually detachable by inserting the Bluetooth module into a housing formed at the center of the neckband And the housing of the neckband can be used as a necklace by making it into an ornamental shape. When the Bluetooth built-in wireless earphone is not used, the housing of the neckband is seen as an ornamental shape, thereby enhancing the appearance as a necklace, Germanium inside (usually germanium gemstones wind In the case of using a wireless built-in type wireless earphone, the earphone of the Bluetooth built-in wireless earphone can be used. In addition, The present invention provides a universal earphone that can be used both as a necklace and as a wireless earphone with a built-in Bluetooth by allowing the earphone and a Bluetooth module to be inserted into a fitting portion and a housing of the neckband, It is possible to eliminate the inconvenience due to the earphone string when worn.

However, the above-described 'Patent Document 1' to 'Patent Document 3' is a technology for a general Bluetooth device, and the advantage offered to the user is somewhat narrow.

That is, it is difficult to provide a variety of functions through the Bluetooth earphone by providing the user with only a simple function of the call or the sound information, so that the limited effect can not be provided.

In particular, the above-described 'Patent Document 1' to 'Patent Document 3' require a device for using a Bluetooth earphone and a Bluetooth earphone, for example, a device such as a user terminal, It is inconvenient to separately provide a charger and a charging cable.

In addition, when the battery of the Bluetooth earphone is discharged during the use of the Bluetooth earphone, since it is no longer possible to output the sound through the earphone, it is necessary to perform sound output through the speaker built in the user terminal or to have a separate wired earphone It is practically impossible to output sound through a speaker built in a user terminal. Therefore, in order to solve such a situation, an external battery for charging the Bluetooth earphone is always provided Or the necessity of always having a Bluetooth earphone and a wired earphone together.

Meanwhile, as technology has been advanced, a technique of charging a user terminal with a wireless charging method has been commercialized. Accordingly, convenience and simplification have been required for a charging method of a device such as a Bluetooth earphone.
