When the cover 120 is opened, the L function or R on each earbud in consideration of the case in which the user's finger or the user's body is detected by an object sensor (not shown) installed on one side of the cover 120. The function can be set.

For example, when the cover 120 positioned adjacent to the user's body is pushed with a finger to open in the first direction, when the cover 120 is opened in the first direction, the object is detected by an object sensor (not shown). Since the user's body or finger will continue to be detected, the control unit has an L function on the earbud located on the left side based on the detected object when the cover 120 is opened in the first direction, and on the earbud located on the right side. R function can be given.

Similarly, when the user pulls the cover 120 positioned away from the user's body with a finger to open it in the second direction, the user's finger is temporarily detected or not detected by the object sensor (not shown). Will not,

When the cover 120 is opened in the second direction, the controller may provide an L function to the earbud located on the left side and an R function to the earbud located on the right side based on the opening direction of the cover 120. The user's convenience can be further improved.

7 is a view showing another embodiment in which the earbuds 200a and 200b are controlled by the controller as the lid 120 is opened.

The portable audio device 100 according to the present invention recognizes whether the cover 120 is opened and the direction in which the cover 120 is opened, and uses each earbud 200a and 200b by using information detected by the object detecting sensor. You can control the function of.

The controller detects the direction in which the cover 120 is opened by using a signal detected by the hall sensor 182, and then controls the function of each earbud 200a or 200b by using the detected information. do.

In addition, the control unit may grant a master function to one earbud and a slave function to the other earbuds.

In order to provide stereo sound outputting sound according to different left and right sound signals, a true wireless stereo (TWS) technology may be used, in which an audio source input from an external terminal is separated into two left and right channels and output. In this case, the direction of the sound output from the master earbud and the sound output from the slave earbud is generally fixed.

When the earbuds 200a and 200b are stored in the case 110 while the cover 120 is closed, the control unit functions as a master in any one of the earbuds 200a and 200b. And other slave earbuds.

Here, when the earbuds operate as a master function, the first function may be performed, and when the earbuds operate as a slave function, the second function may be performed.

The A2DP method is generally used between the earbuds having a master function and the earbuds having a slave function. The basic control is performed on the earbuds performing the master function, and the earbuds acting as the slave function are used in the earbuds serving as the master function. Only separated sound is received and output. Thus, not all of the earbuds need to transmit or receive a control signal.

When the opening of the cover 120 is recognized by the control unit, the portable acoustic apparatus 100 according to the present invention takes into account the power charging state of each earbud 200a or 200b, and the charged power source has a large earbud. It can be given a function as a master, and the earbuds can be given a slave function.

In this case, LED lamps 183a and 183b may be installed at one end of the case 110 based on each of the received earbuds 200a and 200b of the case 110. In this case, when the cover 120 is opened, the controller may control the power to be applied so that light is emitted to the LED lamp 183b in which the earbud 200b to which the master function is applied is located.

The control unit compares the power states charged to the earbuds 200a and 200b, sets the earbuds 200b in a state where a relatively large power is charged, and sets a master function, and a state in which a relatively small power is charged. The earbuds 200a may be set to give a slave function. This ensures efficient power management of each earbud.

That is, as shown in FIG. 7, the controller recognizes a power state charged in each of the earbuds 200a and 200b and then controls to give a master function to the earbud 200b in which the charged power is large. It becomes possible.

8 shows that the earbuds 200a and 200b are controlled by the controller as the cover 120 is opened.

As described above with reference to FIG. 7, the control unit grants a function (L function) to output the sound corresponding to the user's left ear to the earbud 200a positioned at one side based on the direction in which the cover 120 is opened. And, the earbuds (200b) located on the other side can be given a function (R function) to output a sound for the right ear of the user.

In addition, as described above, the controller may assign a master function or a slave function in consideration of a power state charged in each earbud 200a or 200b. As shown in FIG. 8, when the size of the charged power is similar between the earbuds 200a and 200b (including when the charged gauges are the same), the controller arbitrarily provides a master function to one earbud and another earbud. It may be possible to assign a slave function to the master or a master function to both earbuds.

At this time, the LED lamp (183a, 183b) installed in the case 110, so that the user can recognize the earbuds (200a, 200b) to which the master function is given, the control unit LED lamp adjacent to the earbuds to which the master function is given At 183a and 183b, light may be controlled to be irradiated.

9 and 10 are conceptual diagrams showing a state in which the portable acoustic apparatus 100 is set by the mobile terminal.

Here, the mobile terminal is a wearable device capable of exchanging (or interworking) data with the portable acoustic apparatus 100 (eg, smart watch, smart glass, HMD ( head mounted display).

As described above, the control unit may detect whether the cover 120 is opened by detecting that the strength of the magnetic force detected by the hall sensor 182 is reduced, and the control unit may determine whether the magnetic force detected between each hall sensor 182 is detected. After comparing the sizes and recognizing the direction in which the cover 120 is opened, it is possible to control to give an L function or an R function to each earbud accommodated in the case 110. In this case, the controller may be configured to give a master function to one of the earbuds and a slave function to the other earbuds in consideration of the charged power state of each of the earbuds 200a and 200b.

At this time, the mobile terminal can communicate with each of the earbuds (200a, 200b), the controller in consideration of the power charging state of each of the earbuds (200a, 200b), the master function to the earbuds with a high energy level charged to the user It may provide a notification about whether to set the.

When the user applies a touch input to grant the master function to the earbud with a high energy level, the controller allows the master or slave function to be switched between the earbuds 200a and 200b. This is not only when the cover 120 is closed with each earbud accommodated in the case 110 as shown in FIG. 9, but also when the cover 120 is opened as shown in FIG. 10. By notifying the power charging state of the earbuds 200a and 200b and controlling the granting of a master or slave function according to the power charging level of the earbuds 200a and 200b by applying a user's touch input, the device is considered in consideration of the charging state. Enable operation.

The foregoing detailed description should not be construed as limiting in all respects, but should be considered as illustrative.
