For example, a Bluetooth speaker which is connected with a smart phone, and is configured to output music, call voice, and the like received from the smart phone corresponds to the above.
Recently, to increase use of the speaker as described, in addition to a function of outputting an original sound of the speaker, a product which provides a visual effect such as lighting function together therewith is also being released.

Alternatively, the processor 170 may identify one area to output light on the first to fourth LED arrays 120 to 150 according to the features of the image data. Further, the processor 170 may provide a dimming effect by applying driving current to only the plurality of LED modules included in the identified one area to be turned-on.
At this time, the processor 170 may control brightness of each of the LED modules included in the first to fourth LED arrays 120 to 150 with a pulse width modulation (PWM) in which a duty ratio is varied.

However, the above is not limited thereto, and each of the first to fourth driver ICs may be implemented in hardware separate from the processor 170 and include in the speaker 100. For example, the first to fourth driver ICs may be implemented as an LED driver configured to control current applied to the plurality of LED modules included in each of the first to fourth LED arrays 120 to 150.
An embodiment of the disclosure which applies a light emitting method according to a mode of the speaker 100 differently based on a driving method of the processor 170 for the plurality of LED modules included in each of the first to fourth LED arrays 120 to 150 described above will be described below.
According to an embodiment of the disclosure, the processor 170 may emit the first to fourth LED arrays 120 to 150 based on a light emitting method corresponding to a mode of the speaker 100 from among the plurality of light emitting methods, and output sound through the sound outputter 160.
Specifically, the processor 170 may receive an instruction on a mode setting from the user through the input interface. Here, the mode may indicate a driving type of the speaker 100, and may relate to, for example, a driving method for the plurality of LED arrays (e.g., the light emitting method of the first to fourth LED arrays 120 to 150) included in the speaker 100. At this time, the mode for the speaker 100 may be in plurality, and each of a plurality of modes may be set to correspond to each of a plurality of driving types of the speaker 100.
Meanwhile, the light emitting method of the speaker 100 may be set differently according to the driving type of the speaker 100. Accordingly, the processor 170 may identify a mode corresponding to the driving type of the speaker 100, and identify the light emitting method corresponding to the identified mode.
Further, the processor 170 may drive the plurality of LED modules included in each of the first to fourth LED arrays 120 to 150 based on the identified light emitting method. Specifically, image data corresponding to the identified light emitting method may be identified. At this time, the image data may be stored in the memory of the processor 170. Further, the processor 170 may apply, based on the image data, driving current to the plurality of LEDs included in each of the first to fourth LED arrays 120 to 150.
At this time, the processor 170 may apply driving current to the plurality of LEDs included in each of the first to fourth LED arrays 120 to 150 according to a local dimming method. Specifically, the processor 170 may divide the plurality of LED modules included in each of the first to fourth LED arrays 120 to 150 into a pre-set number.
For example, it may be assumed that thirty LED modules are disposed at each of the first to fourth LED arrays 120 to 150. The processor 170 may divide each of the first to fourth LED arrays 120 to 150 into ten blocks. At this time, in each of the ten blocks, three LED modules may be included. Further, the processor 170 may apply driving current to the plurality of LED modules in each block unit. As described above, the processor 170 may turn-on or turn-off the plurality of LED modules include in each of the first to fourth LED arrays 120 to 150 according to the local dimming method. Alternatively, the processor 170 may adjust color and a brightness value of light emitted from the plurality of LED modules included in each of the first to fourth LED arrays 120 to 150 according to the local dimming method.
Meanwhile, the processor 170 may output sound through the sound outputter 160 after emitting the first to fourth LED arrays 120 to 150 based on the identified light emitting method. Specifically, the processor 170 may output sound corresponding to an audio signal stored in the speaker 100 or an audio signal received from the external device (e.g., the user terminal device) connected with the speaker 100 through the sound outputter 160.
Meanwhile, according to an embodiment of the disclosure, the processor 170 may emit, based on the speaker 100 being turned-on based on a user input, the first to fourth LED arrays 120 to 150 based on a first light emitting method corresponding to a first mode.
Specifically, the processor 170 may receive an instruction for turning-on the speaker 100 while the speaker is in a turned-off state. At this time, the instruction may be received through an input interface disposed at one side surface of the housing 110 of the speaker 100. For example, the input interface may include a button for turning-on power of the speaker 100. Further, when the processor 170 detects an operation of the button for turning-on power, power may be applied to the speaker 100, and the speaker 100 may be turned-on. At this time, power applied to the speaker 100 may be output by a power supplying part.
Further, the processor 170 may identify, based on the speaker 100 being turned-on, the operating mode of the speaker as the first mode. Here, the first mode may be a standby mode for receiving a next control command of the user after the speaker 100 has been turned-on.
Meanwhile, the processor 170 may emit the first to fourth LED arrays 120 to 150 based on the first light emitting method corresponding to the first mode when the speaker 100 is turned-on. At this time, the first light emitting method may be a light emitting method by which a process wherein the plurality of LED modules included in each of the first to fourth LED arrays 120 to 150 are sequentially turned-on from LED modules disposed at a center to LED modules disposed at both ends based on a first speed and are then turned-off, and when the plurality of LED modules are turned-off, the plurality of LED modules are sequentially turned-on from LED modules disposed at the center to LED modules disposed at both ends based on a second speed are then turned-off is repeated.

Meanwhile, referring to
Then, the processor 170 may apply driving current to the LED modules disposed in a vertical direction based on the LED modules disposed at the center. Specifically, the processor 170 may simultaneously apply driving current to LED modules of a pre-set number disposed toward an upper side direction and LED modules of a pre-set number disposed toward a lower side direction based on the LED modules disposed at the center that are emitting light. Meanwhile, the pre-set number may be determined based on a dimming method. Further, the pre-set number may be set in a same value for each of the first to fourth LED arrays 120 to 150.
Referring back to the example described above, while the three LED modules disposed at the center of each of the first to fourth LED arrays 120 to 150 are in a state emitting light, the processor 170 may simultaneously apply driving current to the three LED modules disposed at an upper side and the three LED modules disposed at a lower side based on the three LED modules disposed at the center.
Meanwhile, the processor 170 may set sizes of driving current applied to the three LED modules disposed at the upper side and the three LED modules disposed at the lower side differently based on the sizes of driving current applied to the three LED modules disposed at the center and the three LED modules disposed at the center. Through the above, in the LED modules which are turned-on, light having colors and brightness values different from one another may be emitted.
Meanwhile, the processor 170 may progressively increase the number of LED modules which are turned-on from among the plurality of LED modules included in each of the first to fourth LED arrays 120 to 150. That is, the processor 170 may increase the LED modules applied with driving current in the vertical direction based on the LED modules disposed at the center. Referring to
Further, based on the processor 170 may turn-off, based on the LED modules disposed at both ends, that is, from the LED modules disposed at an uppermost end to the LED modules disposed at a lowermost end of the first to fourth LED arrays 120 to 150 disposed vertically at the first side surface and the second side surface being identified as all turned-on, the processor 170 may turn-off the plurality of LED modules included in the first to fourth LED arrays 120 to 150. That is, the processor may cut off the driving current being applied to the plurality of LED modules included in the first to fourth LED arrays 120 to 150.
Further, the processor 170 may repeatedly drive, when the plurality of LED modules are turned-off, the plurality of LED modules to be sequentially turned-on from the LED modules disposed at the center to the LED modules disposed at both ends based on a second speed and then turned-off.
That is, the processor 170 may apply, after the speaker 100 is turned-on, driving current for the plurality of LED modules to be sequentially emitted based on the first speed when the plurality of LED modules included in each of the first to fourth LED arrays 120 to 150 are initially emitted. Further, after the plurality of LED modules included in each of the first to fourth LED arrays 120 to 150 are turned-off, the processor 170 may apply driving current for the plurality of LED modules to be sequentially emitted based on the second speed.
At this time, according to an embodiment of the disclosure, the first speed may be set faster than the second speed. For example, the processor 170 may apply driving current for two seconds to be spent until emitting light from the LED modules disposed at the center to the LED modules disposed at both ends, which are included in each of the first to fourth LED arrays 120 to 150 at initial emission. Further, the processor 170 may apply, after turning-off the plurality of LED modules in each of the first to fourth LED arrays 120 to 150, driving current for four seconds to be spent until emitting light from the LED modules disposed at the center to the LED modules disposed at both ends, which are included in each of the first to fourth LED arrays 120 to 150.
Meanwhile, the first to fourth LED arrays 120 to 150 may be repeatedly emitted based on the second speed. That is, after the first to fourth LED arrays 120 to 150 are emitted one time based on the first speed, the first to fourth LED arrays 120 to 150 may be repeatedly emitted based on the second speed. At this time, the light emitting method of the plurality of LEDs included in each of the first to fourth LED arrays 120 to 150 may be a method by which the LED modules disposed at the center to the LED modules disposed at both ends of the first to fourth LED arrays 120 to 150 are sequentially turned-on as described above.
Meanwhile, in an embodiment of the disclosure, the processor 170 may emit, based on a user input for setting a mode of the speaker to a second mode being received while the speaker 100 is in the first mode, the first to fourth LED arrays 120 to 150 based on a second light emitting method corresponding to the second mode.
At this time, the second light emitting method may be a light emitting method by which a process wherein the plurality of LED modules included in each of the first to fourth LED arrays 120 to 150 are sequentially turned-on from the LED modules disposed at the center to the LED modules disposed at both ends based on the first speed, and when the plurality of LED modules are all turned-on, the plurality of LED modules are then all turned-off is repeated.
Specifically, the processor 170 may receive an instruction corresponding to the second mode through the input interface while in a state of the first mode of the speaker 100 after the speaker 100 has been turned-on. At this time, the instruction corresponding to the second mode may be received through the input interface disposed at one side surface of the housing 110 of the speaker 100. To this end, a button for setting the second mode of the speaker may be included in the input interface. Accordingly, the processor 170 may identify, based on the button for setting the second mode being identified as operated, that an instruction for setting in the second mode has been input, and identify a mode of the speaker 100 as the second mode.
Meanwhile, a button for mode setting may be included in the input interface, and if the button for mode setting is identified as operated by a number of times corresponding to the second mode, the processor 170 may identify a mode of the speaker 100 as an instruction for setting in the second mode as having been input. Alternatively, the processor 170 may receive the instruction for setting in the second mode from the external device through a communicating part.
The processor 170 may identify, based on receiving the instruction corresponding to the second mode, a mode of the speaker 100 as the second mode.
Meanwhile, the processor 170 may emit, based on a user input for setting a mode of the speaker 100 to the second mode being received through the input interface even when the mode of the speaker 100 is in another mode other than the first mode, the first to fourth LED arrays 120 to 150 based on the second light emitting method.

As described, based on the processor 170 sequentially applying driving current to the LED modules disposed at the center to the LED modules disposed at both ends from among the plurality of LED modules included in each of the first to fourth LED arrays 120 to 150, there may be an effect such as light on the speaker 100 spreading out in a vertical direction from the center of the speaker 100.
Meanwhile, every time driving current is applied to a new LED module from among the plurality of LED modules, a value of the driving current applied to the LED module emitting light may be changed. For example, it may be assumed that a block including three LED modules disposed at the center on the first to fourth LED arrays is a first block, a block including three LED modules adjacent with the first block toward an upper direction is a second block, and a block including three LED modules adjacent with the first block toward a lower direction is a third block. At this time, the processor 170 may change, if a level 5 driving current was applied to the three LED modules included in the first block, a level of driving current applied to the three LED modules included in the first block when applying driving current to the three LED modules included in each of the second and third blocks thereafter.
That is, the level of driving current applied to the three LED modules included in each of the second and third blocks may be set to 5, and the level of driving current applied to the three LED modules included in the first block may be changed to 4. Thereby, brightness values and color values of the three LED modules included in the first block and the three LED modules included in each of the second and third blocks may be different. Meanwhile, the processor 170 may change the value of the driving current based on image data.
Meanwhile, according to the second light emitting method, the processor 170 may apply driving current for the first to fourth LED arrays 120 to 150 to repeatedly emit light based on the first speed. Referring back to the above-describe example, the driving current may be applied for two seconds to be spent until emitting light from the LED modules disposed at the center to the LED modules disposed at both ends from among the plurality of LED modules included in each of the first to fourth LED arrays 120 to 150. Further, in this case, the processor 170 may control, by periodically applying the driving current, the first to fourth LED arrays 120 to 150 to repeatedly emit light.
In addition, according to an embodiment of the disclosure, the processor 170 may emit, based on a user input for setting a mode of the speaker 100 to a third mode being received while the speaker 100 is in the first mode, the first to fourth LED arrays 120 to 150 based on a third light emitting method corresponding to the third mode.
Here, a first end may be an area positioned at an uppermost side in the first to fourth LED arrays 120 to 150 disposed in the vertical direction. Meanwhile, a second end may be an area positioned at a lowermost side in the first to fourth LED arrays 120 to 150 disposed in the vertical direction.
At this time, the third light emitting method may be a light emitting method by which a process wherein the plurality of LED modules included in each of the first to fourth LED arrays 120 to 150 are sequentially turned-on from LED modules disposed at the first end to LED modules disposed at the second end based on the first speed and are then turned-off is repeated
Specifically, the processor 170 may receive an instruction corresponding to the third mode through the input interface in the first mode state of the speaker after the speaker 100 has been turned-on. At this time, the instruction corresponding to the third mode may be received through a button setting the third mode included in the input interface which is disposed at one side surface of the housing 110 of the speaker 100. Alternatively, based on the button for mode setting included in the input interface is operated by a number of times corresponding to the third mode, an instruction corresponding to the third mode may be received. Alternatively, an instruction corresponding to the third mode may be received from an external device through the communicating part. Because the above has been described in detail with respect to the second mode, descriptions thereof will be omitted.
The processor 170 may identify, based on receiving an instruction corresponding to the third mode, a mode of the speaker 100 as the third mode.
Meanwhile, the processor 170 may emit, based on a user input for setting a mode of the speaker 100 to the third mode being received through the input interface even when the mode of the speaker 100 is in the second mode (or another mode other than the first mode) and not the first mode, the first to fourth LED arrays 120 to 150 based on the third light emitting method.
Further, the processor 170 may first apply driving current to the LED modules of the pre-set number disposed at the first end from among the plurality of LED modules included in each of the first to fourth LED arrays 120 to 150.
Further, the processor 170 may apply driving current to another LED module positioned at a lower side of the LED modules of the pre-set number disposed at the first end while maintaining the applying of the driving current for the LED modules of the pre-set number disposed at the first end which are included in each of the first to fourth LED arrays 120 to 150. At this time, a number of another LED modules may also match with the pre-set number. Further, the processor 170 may cease applying driving current to the LED modules of the pre-set number disposed at the first end. Thereby, the LED modules of the pre-set number disposed at the first end which were emitting light may be turned-off.
Specifically, referring to
Then, the processor 170 may apply driving current to LED modules of the pre-set number positioned below the LED modules emitting light disposed at the first end of the first to fourth LED arrays 120 to 150 at a t5 time-point. Further, the applied driving current may be cut off for the LED modules disposed at the first end. Accordingly, at the t5 time-point, the LED modules of the pre-set number disposed at the first end of the first to fourth LED arrays 120 to 150 may be turned-off, and the LED modules disposed at the center from among the plurality of LED modules disposed in the first to fourth LED arrays 120 to 150 may be turned-on. Accordingly, the LED modules disposed at the center from among the plurality of LED modules disposed in the first to fourth LED arrays 120 to 150 may emit light.
Meanwhile, the processor 170 may reduce the value of driving current being applied for the LED modules disposed at the first end, and set for the brightness value of the LED modules disposed at the first end to be smaller than the brightness value of the LED modules disposed at the center. Accordingly, at the t5 time-point, the LED modules disposed at the center from among the plurality of LED modules disposed in the first to fourth LED arrays 120 to 150 may output light more brighter than the LED modules disposed at the first end.
Then, the processor 170 may apply driving current to LED modules of the pre-set number positioned below the LED modules emitting light disposed at the center of the first to fourth LED arrays 120 to 150 at a t6 time-point. That is, the processor 170 may apply driving current to the LED modules of the pre-set number disposed at the lowermost side corresponding to the second end of the first to fourth LED arrays 120 to 150. Then, the processor 170 may cease applying the driving current to the LED modules which were emitting light disposed at the center. Accordingly, at the t6 time-point, the LED modules of the pre-set number disposed at the center of the first to fourth LED arrays 120 to 150 may be turned-off, and the LED modules disposed at the second end in the first to fourth LED arrays 120 to 150 may be turned-on. Accordingly, the LED modules disposed at the lowermost side from among the plurality of LED modules disposed in the first to fourth LED arrays 120 to 150 may emit light.
Meanwhile, the processor 170 may reduce the value of driving current being applied for the LED modules disposed at the center, and set for the brightness value of the LED modules disposed at the first end to be smaller than the brightness value of the LED modules disposed at the second end. Accordingly, at the t6 time-point, the LED modules disposed at the second end from among the plurality of LED modules included in the first to fourth LED arrays 120 to 150 may output light more brighter than the LED modules disposed at the center.
Meanwhile, in an embodiment of the disclosure described above, the processor 170 has been described as cutting off driving current to the LED modules which are in an on state after applying driving current to LED modules which are in the off state, but is not limited thereto. That is, the processor 170 may apply driving current to the LED modules which are in the off state after cutting off driving current to the LED modules which are in the on state.
Meanwhile, the processor 170 may sequentially emit the plurality of LED modules included in each of the first to fourth LED arrays 120 to 150 from the LED modules disposed at the first end to the LED modules disposed at the second end.
Specifically, compared to a time spent from after when the LED modules disposed at the first end are turned-on to until the LED modules disposed at the second end are turned-on, a value of a length of the first LED array 120 (or, the second LED array 130, the third LED array 140, the fourth LED array 150) may be a first value corresponding to the first speed. Referring back to the above-described example, the processor 170 may control the driving current being applied to the first to fourth LED arrays 120 to 150 for a time of two seconds to be spent until emitting light from after the LED modules disposed at the front end are emitted to until the LED modules disposed at the second end are emitted from among the plurality of LED modules included in each of the first to fourth LED arrays 120 to 150.
Meanwhile, based on the processor 170 emitting the first to fourth LED arrays 120 to 150 by repeating according to the third light emitting method, there may be a visual effect of light output from the speaker 100 repeatedly falling from the top to bottom on the first to fourth LED arrays 120 to 150.
Meanwhile, according to another embodiment of the disclosure, the processor 170 may sequentially turn-on the plurality of LED modules included in each of the first to fourth LED arrays 120 to 150 from the LED modules disposed at the second end to the LED modules disposed at the first end based on the first speed and then turn-off the same. The above may be a light emitting method set such that a light emitting direction and a light emitting order of the third light emitting method described above are in opposite.
Meanwhile, according to another embodiment of the disclosure, the processor may change the light emitting direction and order of the third light emitting method for every pre-set period. Specifically, the processor 170 may emit, for a first period, the plurality of LED modules included in each of the first to fourth LED arrays 120 to 150 to be sequentially turned-on from the LED modules disposed at the first end to the LED modules disposed at the second end based on the first speed and then turned-off. Further, the processor 170 may emit, for a second period, the plurality of LED modules included in each of the first to fourth LED arrays 120 to 150 to be sequentially turned-on from the LED modules disposed at the second end to the LED modules disposed at the first end based on the first speed and then turned-off.

At this time, the fourth light emitting method may be a light emitting method by which a process wherein the plurality of LED modules included in each of the first to fourth LED arrays are simultaneously turned-on and are then simultaneously turned-off is repeated.
Specifically, the processor 170 may receive an instruction corresponding to the fourth mode through the input interface while in the first mode state of the speaker 100 after the speaker 100 has been turned-on. At this time, the instruction corresponding to the fourth mode may be received through a button for setting the fourth mode included in the input interface which is disposed at one side surface of the housing 110 of the speaker 100. Alternatively, an instruction corresponding to the fourth mode may be received according to a button for mode setting included in the input interface being operated by a number of times corresponding to the fourth mode. Alternatively, an instruction corresponding to the fourth mode may be received from an external device through the communicating part. With respect to the above, because detailed descriptions associated with the second mode have been described, descriptions thereof will be omitted.
The processor 170 may identify, based on receiving an instruction corresponding to the fourth mode, a mode of the speaker 100 as the fourth mode.
Meanwhile, the processor 170 may emit, based on a user input for setting a mode of the speaker 100 to the fourth mode being received through the input interface even when the mode of the speaker 100 is in the second mode (or another mode other than the first mode) other than the first mode, the first to fourth LED arrays 120 to 150 based on the fourth light emitting method.
Further, the processor 170 may emit the first to fourth LED arrays 120 to 150 based on the fourth light emitting method which is a light emitting method that corresponds to the fourth mode.
Specifically, referring to
Further, the processor 170 may cut off, at a t8 time-point which is past the pre-set time, the driving current applied to all of the plurality of LED modules included in each of the first to fourth LED arrays 120 to 150. Accordingly, the plurality of LED modules included in each of the first to fourth LED arrays 120 to 150 may all be turned-off. Accordingly, the first to fourth LED arrays 120 to 150 may all stop emitting light.
The processor 170 may repeat the above-described light emitting process for every pre-set period. For example, if driving current is applied to all of the first to fourth LED arrays 120 to 150, and 0.5 seconds are spent after turning-on all the LED modules included in the first to fourth LED arrays 120 to 150, all the LED modules included in the first to fourth LED arrays 120 to 150 may be turned-off. Further, after 0.5 seconds are spent again, driving current may be applied again to all the LED modules included in the first to fourth LED arrays 120 to 150, and all the LED modules may be turned-on.
Meanwhile, the processor 170 may set the driving current for light colors output from the first to fourth LED arrays 120 to 150 to be the same.
In addition, the processor 170 may set the driving current for the light colors to be changed every time all the plurality of LED modules included in each of the first to fourth LED arrays 120 to 150 are turned-on. For example, the processor 170 may apply, based on all the plurality of LED modules included in each of the first to fourth LED arrays 120 to 150 being initially turned-on, first driving current for light of a first color to be output. Then, the processor 170 may apply, based on all the plurality of LED modules included in each of the first to fourth LED arrays 120 to 150 being turned-off and are then turned-on again, second driving current for light of a second color to be output.
Meanwhile, based on the processor 170 emitting the first to fourth LED arrays 120 to 150 by repeating according to the fourth light emitting method, there may be a visual effect such as light output from the speaker 100 periodically blinking.

Meanwhile, the processor 170 may emit, after emitting the first and third LED arrays 120 and 140 based on the fourth speed, the second and fourth LED arrays 130 and 150 after turning-off the first and third LED arrays 120 and 140. Referring back to the above-described example, the processor 170 may emit, after one second is passed after emitting the first and third LED arrays 120 and 140, the second and fourth LED arrays 130 and 150 after turning-off the first and third LED arrays 120 and 140.
Meanwhile, based on the mode of the speaker 100 being in the fifth mode, the processor 170 has been described as selectively applying the fifth light emitting method or the sixth light emitting method, but is not limited thereto. That is, the processor 170 may identify, based on a user input for setting the fifth mode being input, the mode of the speaker 100 as the fifth mode, and emit the first to fourth LED arrays 120 to 150 by applying both the fifth light emitting method and the sixth light emitting method. At this time, the processor 170 may randomly set an application order of the fifth light emitting method and the sixth light emitting method.
Meanwhile, according to an embodiment of the disclosure, the processor 170 may apply all the second to fourth light emitting methods described above in one mode. For example, the processor 170 may emit, based on a user input for setting the sixth mode being received, the first to fourth LED arrays 120 to 150 by sequentially applying the second to fourth light emitting method in random order.
Meanwhile, the processor 170 may set a time period in which the first to sixth light emitting methods are repeated based on sounds output through the sound outputter 160.
Specifically, according to an embodiment of the disclosure, the speaker 100 may further include a microphone. At this time, the processor 170 may identify, based on sounds obtained through the microphone, a beat per minute (BPM) of a sound, and set a period time corresponding to the sound output from the speaker based on the identified BPM. Further, the processor 170 may repeatedly emit the first to fourth LED arrays 120 to 150 based on the light emitting method corresponding to the mode of the speaker 100 according to a set period time.
More specifically, the processor 170 may obtain sounds output through the sound outputter 160 through the microphone. Further, the processor 170 may analyze the obtained sound, and identify the BPM of the sound. Further, a time period corresponding to the identified BPM may be set. For example, if the BPM is identified with a high value, the processor 170 may identify the sound output through the sound outputter 160 as of a fast tempo. Further, the processor 170 may set a light emitting period of the LED modules to be short so as to corresponding to the fast tempo of the identified sound. Conversely, if the BPM is identified with a low value, the processor 170 may identify the sound output through the sound outputter 160 as of a slow tempo. Further, the processor 170 may set a light emitting period of the LED modules to be long so as to corresponding to the slow tempo of the identified sound. Meanwhile, the processor 170 may repeatedly apply driving current to the plurality of LED modules included in each of the first to fourth LED arrays 120 to 150 by repeating according to the set time period. Because the above has been described above, descriptions thereof will be omitted.

Meanwhile, a mode of the speaker may indicate a driving type of the speaker 100, and for example, may relate to a driving method for the plurality of LED arrays (e.g., the light emitting method of the first to fourth LED arrays 120 to 150) included in the speaker 100. Meanwhile, the mode for the speaker 100 may be in plurality, and each of the plurality of modes may be set to correspond to each of the plurality of driving types of the speaker 100.
Then, the processor 170 may emit the first to fourth LED arrays 120 to 150 based on the light emitting method corresponding to the mode of the speaker 100 from among the plurality of light emitting methods (S1220). Specifically, the processor 170 may identify the light emitting method corresponding to the mode of the speaker 100, and obtain image data corresponding to the identified light emitting method from the memory. Further, the processor 170 may control, based on the image data, driving current to adjust the brightness of the plurality of LED modules included in each of the first to fourth LED arrays 120 to 150.
Then, the processor 170 may output sound through the sound outputter 160 (S1230). Specifically, the processor 170 may output sound corresponding to an audio signal stored in the speaker 100 or an audio signal received from an external device (e.g., the user terminal device) connected with the speaker 100 through the sound outputter 160.
The speaker 100 may include the housing 110, the first LED array 120, the second LED array 130, the third LED array 140, the fourth LED array 150, an input and output interface 180, and a communication interface 190.
