If it is analyzed, it is desirable to set the noise mode.

Further, when the external device is a mobile communication terminal, the call mode or the music mode setting is automatically set to a call mode when the controller detects a call state signal of the mobile communication terminal, and the control unit sets the mobile communication terminal. It is preferable to automatically set the music mode when the music playback signal is detected.

It is provided to fully inform the person having the scope of the invention, which is defined only by the scope of the claims.

Also, terms used herein are for the purpose of illustrating embodiments and are not intended to limit the invention. In the present specification, the singular form includes plural forms unless otherwise specified in the specification. &Quot; comprises "and / or" comprising "used in the specification do not exclude the presence or addition of components other than the components mentioned. Unless defined otherwise, all terms (including technical and scientific terms) used herein may be used in a sense commonly understood by one of ordinary skill in the art to which this invention belongs.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings in order to describe the present invention in more detail. Like reference numerals refer to like elements throughout.

1, the first earphone unit 110 includes a first microphone 410, and the first earphone unit 110 and the second earphone unit 120 both include a speaker 310. , 320). The first earphone unit 110 including the first microphone 410 is inserted into one of both ears of the person, and the second earphone unit 120 is inserted into the other ear.

The first earphone unit 110 includes a first speaker 310 and a first microphone 410, the first earphone unit 110 is the first speaker 310 and the first microphone 410 is integrated It is inserted into the ear canal of the user's ear. The user speaks and hears through the earphone unit inserted into the ear. In other words, the speaker and the microphone are located in the ear so that external noise does not flow into the microphone, so that the user can talk to the other party in a noisy environment and both hands can freely increase work efficiency.

Here, the speakers 310 and 320 may use a sealed armature speaker and / or a piezoelectric speaker to improve sound quality as a dynamic speaker. This can reduce white noise. In addition, the first microphone 410 preferably uses a directional microphone component that is robust against noise. Since the first microphone 410 receives a signal generated from an ear as an input signal when a user speaks, a microphone having a directional characteristic is preferable, but an omnidirectional microphone may be used.

In addition, the outside of the earphone unit may suppress the noise generated when the wind noise hits the earphone units 110 and 120, and may form the outside of the earphone unit with silicon for waterproofing the earphone units 110 and 120.

The signal transceiver 210 is a part that transmits and receives a signal with an external device (eg, a mobile communication terminal). For example, the signal transceiver 210 transmits / receives a music signal and a voice signal to a mobile communication terminal, which is an external device, using Bluetooth communication.

The controller 220 controls the earphones 110 and 120 and the signal transceiver 210. Basically, the controller 220 transmits a voice signal input to the first microphone 410 to an external device, transfers a music signal received from the external device to the speakers 310 and 320, and receives the voice signal received from the external device. To control the delivery to the second speaker 320.

The main body 200 may be provided with a control device for adjusting the speaker volume, a device for turning on / off the output of the ear set, and the like. Furthermore, the earset of the present invention may include a call button for determining whether to talk with a mobile communication terminal which is an external device.

In the present invention, the mode setting unit 250 can be configured as shown in FIG. 2 so that a clean call can be made in a call mode, and rich music sounds can be heard in a music mode. On the other hand, the arrangement of the control unit 220 and the mode setting unit 250 can be changed and the signal transceiver 210 may be unnecessary in the wired ear set.

In FIG. 2, when the switch 251 is in a call mode, terminal 2 is connected to terminal 1 and terminal 5 is connected to terminal 4. In the music mode, terminal 2 is connected to terminal 3, and terminal 5 is connected to terminal 6.

A speaker output control circuit 252 is connected between the first terminal of the switch 251 and the first speaker 310. When the switch 251 is placed in a call mode, the speaker output is output to the speaker output control circuit 252. The first speaker 310 is output to the first speaker 310, and when the switch 251 is set to the music mode, the first speaker 310 is directly output to the first speaker 310 without passing through the speaker output control circuit 252. At this time, the speaker output control circuit 252 is preferably composed of a resistor. On the other hand, when the output level of the external device (eg, the mobile communication terminal) is lower than a predetermined standard, the speaker output control circuit 252 may be unnecessary. That is, if the output level of the external device is higher than a predetermined standard, the output of the first speaker 310 is also high and is transmitted to the first microphone 410 so that an echo phenomenon may occur when talking with the other party.

Between the third terminal of the switch 251 and the first speaker 310, a speaker matching circuit consisting of a circuit such as R, L, C, etc. in order to ensure that the speaker output is well transmitted to the first speaker 310 ( 253 may be further provided.

For the same reason, the second speaker 320 may further include a separate speaker matching circuit including R, L, and C circuits so that speaker output can be transmitted to the second speaker 320 well. It is apparent that a separate speaker output control circuit may be further provided to adjust the output of the second speaker 320.

Since the speaker output control circuit and the speaker matching circuit are further provided as described above, the volume of the first speaker 310 is lower than that of the second speaker 320 when listening to music in the call mode, and the volume in the call mode. Is less in both the first and second speakers 310,320 compared to the volume in the music mode. The reason is that the output is adjusted to prevent the volume of the first speaker 310 from being input to the first microphone 410, and the second speaker 320 is balanced to balance the first speaker 310. This is because the output of is also adjusted.

As a result, the speaker output control circuit and the speaker matching circuit perform a function of balancing left and right and outputting sound of high quality.

In addition, the fourth terminal of the switch 251 is provided with a call button 254 having one end connected to the ground, so that the user can operate in the call mode.

In addition, a microphone matching circuit 255 may be provided between the fourth terminal of the switch 251 and the first microphone 410 so that an input signal of the first microphone 410 can be well transmitted to the other party. In this case, the microphone matching circuit 255 may include a Zener diode (R, L, C, etc.). At this time, the zener diode functions to protect the first microphone 410.

In addition, a dummy resistor 256 is connected to the sixth terminal of the switch 251. The reason for this is that when terminal 5 of the switch 251 is separated from terminal 4, that is, when there is no input signal of the first microphone 410, the external device (eg, a mobile communication terminal) is provided. Since the microphone is operated, the dummy resistor 256 should be provided so that the external device recognizes that the first microphone 410 is continuously connected.

If the dummy resistor 256 is not present, when a call is made with the other party in the music mode, the microphone provided in the external device operates to make a call with the other party in a noisy environment. However, due to the dummy resistor 256, the external microphone recognizes the dummy resistor 256 as an external microphone so that the microphone itself does not operate. Therefore, the user's voice is not transmitted to the other party, so the user calls after switching from the music mode to the call mode.

In the present invention, the call mode and the voice mode have the following meanings. The call mode is a mode for operating a phone call with a counterpart via a mobile communication terminal (external device), and the music mode is a mode for operating music or video through a mobile communication terminal to listen to a sound.

When playing and listening to a video such as music or a movie through a mobile terminal, constant stereo sound quality is important. In the present invention, since the first earphone unit 110 includes the first microphone 410 and the first speaker 310, when there is no separate output control circuit, when the user talks with the other party in the call mode, The voice output from the speaker 310 may be inputted to the first microphone 410, and an echo and howling may occur when talking with the other party.

In order to prevent the echo and howling as described above, a method of reducing the output of the first speaker 310 or reducing the sensitivity of the first microphone 410 may be used, in order to reduce the output of the first speaker 310. An output control circuit is inserted into the output terminal. However, in this case, the low band is attenuated when listening to music, which causes a problem of not being able to hear rich music. Therefore, in order to solve this problem, the circuit may be configured not to pass through the output control circuit 252 of the first speaker 310 in the music mode by using a switch.

The function of the controller 220 and the mode setting unit 250 for controlling the call mode and music mode is to control the mode by grasping the call state or the music playback state manually or automatically. Of course, the functions of the controller 220 and the mode setting unit 250 may be configured in the user's device (cell phone).

In this embodiment, by using a switch or a voice recognition function or a sensor or an application, it can be automatically or manually moved from the music mode to the call mode to talk with the other party through the first microphone 410 in the ear.

As a result, the first microphone 410 does not operate in the music mode, and when the music is heard in the call mode, the speaker output is reduced due to the output control circuit 252. In the music mode, the dummy resistor 256 may be removed to talk to the other party using a microphone of an external device (eg, a mobile communication terminal).

Meanwhile, as shown in FIG. 3, the second microphone 420 may be connected to the outside of the dummy resistor 256 at the sixth terminal of the switch 251. The arrangement of the second microphone 420 may be disposed between the main body 200 or the earphone units 110 and 120 and the main body 200 of FIG. 1. In this case, it is divided into a noise mode and a normal mode. When listening to music in the noise mode, the volume of the first speaker 310 is lower than that of the second speaker 320 than the normal mode. In both of the speakers 310 and 320 in the noise mode, the volume is lower than in the normal mode. The reason is that an output control circuit is required to prevent echo and howling, so that the volume is low. However, if the signal output from an external device (eg, a mobile communication terminal) is below a certain reference level, the speaker output control circuit 252 may be unnecessary. Meanwhile, the difference between FIG. 2 and FIG. 3 is that the second microphone 420, which is an external microphone, is electrically connected instead of the dummy resistor 256. Accordingly, the call mode and the music mode of FIG. 2 correspond to the noise mode and the normal mode of FIG. 3, respectively. Therefore, all descriptions of mode change should be regarded as talk mode as noise mode and music mode as normal mode.

In FIG. 3, in a noise environment, a switch or a voice recognition function or a sensor or an application may be used to automatically or manually move from the normal mode to the noise mode to talk with the other party through the first microphone 410 in the ear. In a quiet environment, the normal second mode is automatically or manually switched to operate the external second microphone 420 to make a clearer call than when talking to the first microphone 410. Meanwhile, FIG. 2 and FIG. 3 show the second speaker 320, which is additionally necessary for listening to music on stereo. That is, the second speaker 320 may be unnecessary only for a simple call with the other party. In addition, when the external device is a radio, the second speaker 320 may be unnecessary even more because only a call is used.

mode  Setting and control

Hereinafter, control according to a call mode (noise mode) and a music mode (normal mode) will be described. Mode control described below is performed by the controller 220 or the mode setting unit 250 illustrated in FIG. 1. The controller 220 and the mode setting unit 250 may be disposed between the first earphone unit 110 and an external device (mobile communication terminal) or disposed in the external device according to the wired or wireless earset.

When the user manually determines the call mode (silence mode) or the music mode (normal mode) through a separate switch, voice recognition or motion sensor, etc., is referred to as the manual mode, and the control unit 220 or the mode setting of the present invention. When the unit 250 automatically sets the call mode (silence mode) / music mode (general mode) according to the environment is called an automatic mode. First, let me explain how manual mode or automatic mode can work. In other words, we want to see in what order or mode the mode execution proceeds.

Mode execution  First Embodiment

The controller 220 or the mode setting unit 250 is basically controlled in the manual mode. In other words, the user using the earset device selects the call mode or music mode operation. Although not shown in the drawings, the manipulation may be performed through at least one of a switch, a voice recognition, and a motion sensor disposed in the main body 200. In this case, it will operate in the already set mode unless you have special choice. Furthermore, the mode may be manually set through an application running on the mobile communication terminal.

Mode execution  Second Embodiment

The earset device of the present invention can also be set in advance to operate in manual or automatic mode. In this case, it can be set through a switch for selecting a manual mode or an automatic mode, voice recognition, or a motion sensor. It can also be set through an application installed in the mobile communication terminal.

If the manual mode is set, the earset device of the present invention waits for a user's input or operates in a preselected mode as in the first mode setting. If the automatic mode is set, the earset device of the present invention operates in the automatic mode described below. Setting the manual mode or the automatic mode is called first mode setting.

Mode execution  Third Embodiment

The earset device of the present invention is operated in the manual mode according to the user's selection if the user's operation when the sound signal is transmitted to the earphone device, and in the automatic mode if the user's operation is not. Of course, even if you are operating in the automatic mode, if the user manually operates it operates in the call mode or music mode according to the operation. In order to distinguish it from the second embodiment, selecting or setting the music mode or the call mode is called setting the second mode.

Manual mode basically operates according to user input, but other types of operation are possible. Some embodiments will be described.

Manual mode  First Embodiment

In the most basic manual mode, a user sets a call mode or a music mode through an external terminal such as a switch or an interface of a mobile communication terminal interworking with an earset device.

Manual mode  Second Embodiment

When a user inputs a specific voice command through the first microphone 410 of the earset device, the earphone device recognizes the voice and operates in the call mode or the music mode according to the voice command. For example, when the user inputs "call", the call mode may operate, and when the user inputs "music", the music mode may operate.

Manual mode  Third Embodiment

The particular operating sensor placed on the earset device or mobile communication terminal determines the call mode or music mode. For example, by using a gyro sensor or the like, the user may shake the mobile communication terminal or the earset device a predetermined number of times, or move in a predetermined shape to determine a call mode or a music mode. It is obvious that the call mode or the music mode may be determined through various sensors available to those skilled in the art.

On the other hand, when the user is listening to music in the manual mode (music mode) and the phone is pressed and the call button is placed on the mobile communication terminal or the body of the earset device, the control unit controls to switch to the call mode along with the call connection. . It is possible to have an input means for switching to the call mode separately from the call button, but it is preferable to press the call button to switch the call and the call mode. When the user presses the call button again to input again to switch to the call mode, it is cumbersome and there is a possibility that an echo phenomenon may occur.

Meanwhile, the above-described manual modes may be set or performed by a user operation through an application executed in the mobile communication terminal.

Each embodiment will be described in more detail with respect to the automatic mode. In the following description of the automatic mode, it is assumed that the controller 220 performs overall control for convenience of description. Of course, the mode setting unit 250 may control the automatic mode described later.

Auto mode  First embodiment

The mobile communication terminal has an identification signal or an identification code unique to the mobile communication terminal in the case of call operation and music reproduction. For example, in a telephone call, 001 has an identification code (call state signal), and in the case of music reproduction, it has another identification code (002). The identification signal or the identification code may vary depending on the mobile communication terminal, but the identification code defined by a certain operation is unified for each product. The first embodiment uses this identification signal or identification code. When a mobile communication terminal device, which is an external device, is in a call operation, the signal transmission / reception unit 210 may receive the identification signal or the identification code as well as exchange a voice signal with the signal transmission / reception unit 210. When the 001 code is received using the identification signal or the identification code, the controller 220 controls the earset device of the present invention in accordance with a call mode. That is, in the call mode, the output of the first speaker 310 is cut off, and the first microphone 410 receives the voice while the second speaker 320 outputs the voice of the other party. When the 002 code is received, the controller 220 controls the earset device according to the music mode. In the music mode, the sound is output through all the speakers 310 and 320 so that the user can listen to the stereo music.

Auto mode  Second Embodiment

Recently, with the spread of smart phones, mobile communication terminals with various functions have appeared. Smartphones perform various functions by running individual applications. Voice calls, MP3 music playback, or video playback are all done through separate applications. When various applications operate, individual identification signals or identification codes are generated as in the first embodiment. Accordingly, the controller 220 may control the earset device to operate in a call mode or a music mode by receiving a signal generated by an application.

Auto mode  Third embodiment

Furthermore, an application for controlling the earset device of the present invention may be installed in a smartphone, and the earset device may be controlled through the control application. That is, the controller 220 does not control to perform the call mode or the music mode operation, but controls the earset device by determining whether the call mode or the music mode is performed in the control application. The controlling application analyzes the call operation or music playing state of the smartphone and transmits the analyzed result to the earset device of the present invention to perform the call mode or the music mode operation.

Auto mode  Fourth embodiment

In another embodiment, the controller 220 analyzes a sound signal received by the earset device through the signal transceiver 210, and sets a call mode or a music mode based on the analysis result. The sound signal is largely divided into a voice signal and a music signal. The voice signal is a sound signal composed purely of human speech, and the music signal is a signal of sound generated when playing music.

Sound can be represented physically as waveforms. Analyze frequency intensity, waveform height, and waveform regularity. The distinction between the voice signal and the music signal described above is the core of the present embodiment.

The distinction between the voice signal and the music signal by analyzing the height, the amount of change, and the regularity of the frequency for a certain period of the sound signal can be performed by a person of ordinary skill in the art in various ways, and thus a detailed description thereof will be omitted. . For example, the voice signal and the music signal may be distinguished according to whether the average value of the frequency change amount disclosed in Korean Patent Laid-Open Publication No. 10-2010-0098100 exceeds a threshold.

In the control unit 220 of the present invention, the voice signal (noise environment) and the music signal (quiet environment) may be distinguished and set to a call mode (noise mode) or a music mode (music mode). Furthermore, as described in the third embodiment, the sound signal output from the smart phone is distinguished from the voice signal or the music signal through the application driven on the smart phone, and the analyzed result is transmitted to the earset device of the present invention. You can also control the automatic mode of operation.

Figure 4 is a flow chart showing the operating sequence of the ear set according to the present invention.

The mode execution 1, the mode execution 2, and the mode execution 3 each show a procedure according to the embodiment in which the above-described modes are executed. On the other hand, the manual mode and the automatic mode are indicated by dotted boxes, respectively. The dotted line box shown on the left side of FIG. 4 is the manual mode, and the dotted line box shown on the right side corresponds to the automatic mode operation. Meanwhile, although FIG. 4 has been described with reference to the drawing of FIG. 2, the same applies to the drawing of FIG. 3. That is, it is preferable that the call mode and the music mode of FIG. 2 correspond to the noise mode and the normal mode of FIG. 3, respectively.

Mode execution 1 means the user manually selects a call mode (silent mode) or a music mode (normal mode) without executing the automatic mode.

Mode execution 2 operates in the manual mode or the automatic mode according to the user preset. Therefore, after receiving the external device signal (S1), it is necessary to determine whether the preset mode is the manual mode or the automatic mode (S2). It operates in the set mode according to the judgment. If the preset mode is the manual mode (first mode) and the user does not select the first mode newly, the second mode set immediately before is performed.

Mode execution 3 is the manual mode when the user selects the call mode or the music mode (second mode) after receiving the external device signal (S1), and enters the manual mode, and if there is no input from the user, the automatic mode is activated. Is executed. Even while operating in the automatic mode, if the user manually selects the music mode or the call mode (S4), the corresponding mode is manually changed, and if there is no input from the user, the automatic mode continues to run.

The automatic mode operation will be described further. As described in the above-described embodiment of the automatic mode, the mode analysis can be performed in various ways. If it is determined that the received signal is a music signal (quiet environment) as a result of the mode analysis, the earset device of the present invention operates in the music mode (normal mode) through the control unit 220. On the contrary, if it is determined that the received sound signal is a voice signal (noise environment) as a result of the mode analysis, the earset device of the present invention operates in a call mode (noise mode) through the control unit 220.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be appreciated that one embodiment is possible. Accordingly, the true scope of the present invention should be determined by the technical idea of the claims.
