1 is a diagram for explaining connection between a terminal and an ear microphone in an embodiment.

A reception signal (reception sound) input to the terminal 100 can be generated at the core-end server, but it is difficult for the terminal itself to generate a transmission signal (transmission sound) generated at the terminal 100. [ To this end, in the embodiment of the present invention, it is possible to provide a method of loop-back the transmission signal of the terminal using the ear microphone 200 inserted in the ear jack 110 of the terminal 100. Hereinafter, the reception signal (reception sound) is a signal generated at a core-end server such as a base station and transmitted to the terminal 100, and a transmission signal (transmission sound) refers to a signal generated at the terminal 100 and transmitted to the base station.

The terminal 100 may correspond to various terminals providing a wireless communication function such as a smart phone and a feature phone. The terminal 100 may include an ear jack 110 (for example, an earphone, a headphone, etc.) ). The position of the ear jack 110 is not limited to the upper end, the lower end, or any position of the terminal.

The ear microphone 200 according to the embodiment is provided in a form including a terminal to be inserted into the ear jack 110. For example, it is possible to provide a method of looping back a transmission signal to a terminal by re-inputting a reception signal received from a base station and output from a terminal 100 via a microphone 200 to a terminal 100 in the form of a sound source .

The microphone 200 may include a speaker terminal, a microphone terminal, and a capacitor. When the microphone 200 is connected to the ear jack 100, the ear microphone 200 is input to the terminal, To the microphone terminal of the ear microphone 200, converts the received signal into a transmission signal, and inputs the transmission signal to the terminal 100. [

When transmitting a transmission signal from a speaker terminal to a microphone terminal, when the microphone terminal is directly connected to the speaker terminal, a malfunction may occur in the terminal 100 due to a voltage difference, and a current or voltage The terminal 100 may fail. As another example, the terminal 100 may misunderstand the voltage or the voltage input to the microphone terminal by operating the button of the ear microphone. Therefore, when the microphone terminal is directly connected to the speaker terminal, it is impossible to normally transmit the transmission signal to the terminal 100 due to the malfunction described above, and it may be difficult to generate a transmission sound source for loop back.

According to one embodiment, a capacitor is used when connecting the speaker terminal and the microphone terminal. The detailed configuration will be described below with reference to FIG. 2 and FIG. In the embodiment, if a capacitor is connected between the speaker terminal and the microphone terminal, the transmission signal can be transmitted to the terminal 100 without malfunction of the terminal 100.

Through the connection as shown, a transmission signal input to the speaker terminal 203 or 204 through the terminal can be transmitted to the microphone terminal 201. At this time, the capacitor 205 can solve the problem of a sudden voltage drop .

A voltage difference occurs between the microphone terminal 201 and the speaker terminal 203 or 204 when a call is made after inserting the microphone 200 into the terminal. Since the voltage is higher than the microphone terminal 201, if a direct connection is made without the capacitor 205, a high current can be introduced into the microphone terminal 201. [ Thereafter, due to the current flowing into the microphone terminal 201, a call malfunction may occur in the terminal due to a call type of call, voice recognition, etc., and the call may be automatically terminated, and an operation of converting the transmission signal and transmitting the transmission signal to the terminal may be performed I can not.

The microphone terminal 201 and the speaker terminal 203 or 204 can be connected through the capacitor 205 to solve the voltage drop between the microphone terminal 201 and the speaker terminal 203 or 204. [ In the embodiment, the amount of current (the amount of charge per hour) flowing from the speaker terminal 201 to the microphone terminal 203 or 204 can be controlled by the capacitor 205.

For example, the capacitor 205 may have a value of 10 uF, and may have a relatively large capacitance among the commonly used capacitors. In an embodiment, the capacitance of the capacitor 205 may be set such that the signal coming from the speaker terminal 201 to the microphone terminal 203 or 204 is separated from the signal from the button input of the ear microphone.

The loop back line can be used to loop back a signal transmitted from the base station to the terminal during a call using the terminal to the base station.

In the embodiment, when the microphone 200 is inserted into the terminal, since the terminal can perform the same processing as the insertion of the earphone or the like, the speaker of the terminal is silenced and no sound is outputted through the speaker of the terminal have.

3 is an example of an actual shape of the ear microphone in one embodiment.

The ear microphone 200, which is actually implemented by applying the concept of the embodiment of FIG. 2, may be provided in a form of connecting the capacitor 205 using the inner wall of the ear microphone 200.

In an embodiment, the capacitor 205 having a capacitance of 10 uF may be connected to the inner side of the microphone terminal 201 and the inner side of the speaker terminal 203 or 204, as shown, depending on its size.

The speaker terminal 201 and the speaker terminal of the earphone jack are connected to each other through the outer surface of the ear microphone 200. The microphone terminal 203 or 204 and the earphone jack microphone terminal are connected through the outer surface of the ear microphone 200 .

The microphone terminal 201 and the microphone terminal 201 can be controlled so that the button operation of the microphone 201 does not occur when the reception signal is inputted into the terminal through the connection of the capacitor 205. In this embodiment, It is possible to solve the problem caused by the sudden voltage drop between the electrodes.

4 is a diagram for explaining a measurement scenario for a transmitted sound in one embodiment.
