[0093] The straight section 1013 may connect the first curved section 1011 and the second curved section 1012. The straight section 1013 may extend along the straight top side of the speaker 100.

[0094] Although the light of the first light source 100Lb is provided to the end 101a of the lighting tube 101, the brightness of the lighting tube 101 may be lower as it is farther from the end 101a. The brightness of the straight section 1013 may be lower than the brightness of the first curved section 1011. The brightness of the central portion of the straight section 1013 may be lower than the brightness of the portion of the straight section 1013 adjacent to the first curved section 1011.

[0095] Although the light of the second light source 100Rb is provided to the other end 101b of the lighting tube 101, the brightness of the lighting tube 101 may be lower as it is farther from the other end 101b. The brightness of the straight section 1013 may be lower than the brightness of the second curved section 1012. The brightness of the central portion of the straight section 1013 may be lower than the brightness of the portion of the straight section 1013 adjacent to the second curved section 1012.

[0096] The optical sheet 102 may be located behind the lighting tube 101 and may extend along the lighting tube 101. The optical sheet 102 may be a thin sheet covering the rear of the lighting tube 101. The optical sheet 102 may be a diffusion sheet. The optical sheet 102 may be a reflection sheet. The length of the optical sheet 102 may be less than the length of the lighting tube 101.

[0097] The first curved section 1021 may form one end 102a of the optical sheet 102 and may be bent. The first curved section 1021 may extend along the first curved section 1011 of the lighting tube 101 and may cover a portion of the rear of the first curved section 1011. Since a portion of the first portion 1011a of the first curved section 1011 is arranged relatively close to the first light source 100Lb and relatively bright, it may not be covered by the optical sheet 102. The second portion 1011b is not only adjacent to the first light source 100Lb and relatively bright, but also bends toward the inside of the frame 100F, and therefore may not be covered by the optical sheet 102.

[0098] The second curved section 1022 may form the other end 102b of the optical sheet 102 and may be bent. The second curved section 1022 may extend along the second curved section 1012 of the lighting tube 101 and may cover a portion of the rear of the second curved section 1012. A portion of the first portion 1012a of the second curved section 1012 is arranged relatively close to the second light source 100Rb and relatively bright, and therefore may not be covered by the optical sheet 102. The second portion 1012b is not only adjacent to the second light source 100Rb and relatively bright, but also bends toward the inner side of the frame 100F, and therefore may not be covered by the optical sheet 102.

[0099] The straight section 1023 may connect the first curved section 1021 and the second curved section 1022. The straight section 1023 may extend along the straight section 1013 of the lighting tube 101 and may cover the rear of the straight section 1013.

[0100] This can minimize the brightness difference of light caused by the different distances from the plurality of light sources 100Lb and 100Rb. It can minimize the brightness difference of light in the area corresponding to the optical sheet 102. It can minimize the brightness difference of light formed along the edge of the speaker 100.

[0101] Reference Fig.15 and Fig.16 , the lens 103 may be located in front of the lighting tube 101. The lens 103 may be located on the opposite side of the optical sheet 102 relative to the lighting tube 101. The lens 103 may be located between the rear housing 108 and the front housing 109. A portion of the lens 103 may form a portion of the outer side of the speaker 100. The portion of the lens 103 may have a band shape surrounding the speaker 100. The lens 103 may include a resin material. The lens 103 may include a first portion 103a and a second portion 103b.

[0102] The first portion 103a may be located between the lighting pipe 101 and the front housing 109. The first portion 103a may be located at an opposite side of the optical sheet 102 relative to the lighting pipe 101. The first portion 103a may extend along an edge of the frame 100F. The first portion 103a may be referred to as a horizontal portion 103a.

[0103] The second portion 103b may cross the first portion 103a and may face the optical sheet 102. The second portion 103b may extend along the first portion 103a and may cover the lighting tube 101. The second portion 103b may be located between the rear housing 108 and the front housing 109 and may form an edge of the speaker 100. The optical sheet 102 may be located between the second portion 103b and the rear housing 108. The second portion 103b may be referred to as a vertical portion 103b. The frame 100F, the optical sheet 102, the first portion 103a, and the second portion 103b may form a space for the lighting tube 101 to be disposed.

[0104] The third portion 103c may intersect the first portion 103a. The second portion 103b may be formed on one side (back side) of the first portion 103a facing the optical sheet 102, and the third portion 103c may be formed on the other side (front side) of the first portion 103a. The third portion 103c may face a portion of the inner side of the front housing 109.

[0105] Therefore, as the optical module 100A (see Fig.13 ), the light guided by the lighting tube 101 and the optical sheet 102 can be irradiated to the outside through the lens 103. Under the action of the optical sheet 102, the brightness difference of the light at different positions in the interval of the lens 103 can be minimized. The color of the light emitted from the lens 103 can be diverse. The light emitted from the lens 103 can be used to display the state of the speaker 100. For example, various states of the speaker 100 can be displayed by adjusting the color, brightness, whether the light emitted from the lens 103 is on or off, etc. The state of the speaker 100 may include whether the power of the speaker 100 is on / off, the volume, the beat of the sound played, whether it is connected to the Bluetooth of the display 10, etc. The user can control whether the optical component 100A is activated or not.

[0106] In addition, the lens 103 may block a gap between the rear housing 108 and the front housing 109 .

[0107] Reference Fig.17The display 10 may include a display panel 11, a plurality of boards PSU, MB, TC, a built-in speaker SPK, a user interface UI, a wireless communication interface CI and a memory M.

The power supply may provide power to the plurality of components of the display 10. For example, the power supply may be a battery Bt (refer to Figure 1 ).

[0108] The memory M may store programs, applications, data, etc. required for driving and controlling the display 10.

[0109] The user interface UI may transmit a signal input by the user to the controller C. The display 10 may provide a signal to the user or the user's terminal through the user interface UI. For example, the user interface UI may be a power button, a channel button, a volume button, a setting button, and the like.

[0110] The wireless communication interface CI can perform communication with an external device. The external device can send and receive information and / or signals with the controller C of the display 10 through the wireless communication interface CI. For example, the external device can be a speaker 100. The wireless communication interface CI can utilize Bluetooth (Bluetooth TM ), RFID (Radio Frequency Identification), Infrared Data Association (IrDA), UWB (Ultra Wireband), ZigBee, NFC (NearField Communication), Wi-Fi (Wireless-Fidelity), Wi-Fi Direct, and Wireless USB (Wireless Universal Serial Bus) technologies to perform wireless communication.

[0111] The remote control device 300 can wirelessly transmit and receive information and / or signals with the display 10 through the wireless communication interface CI. The user can use the remote control device 300 to control the display 10. For example, the user can use the remote control device 300 to turn on / off the display 10, or increase or decrease the volume, or change the channel.

[0112] The external speaker 100 can wirelessly transmit and receive information and / or signals with the display 10 via the wireless communication interface CI.

[0113] Reference Fig.18The speaker 100 may include a speaker unit 100S, an optical component 100A, a user interface 100U, a wireless communication interface 100W, and a memory 100M. The above-mentioned plurality of components may be electrically connected to a controller 100C of the speaker 100. For example, the controller 100C may be mounted on a frame 100F of the speaker 100 (see Fig.15 ). The power source may provide power to a plurality of components of the speaker 100. For example, the power source may be an external power source, and may provide power to the speaker 100 via a power cable. As another example, the power source may be a battery built into the speaker 100.

[0114] The memory 100M can store programs, applications, data, etc. required for driving and controlling the speaker 100 .

[0115] The user interface 100U may transmit a signal input by the user to the controller 100C. The speaker 100 may provide a signal to the user or the user's terminal through the user interface 100U. For example, the user interface 100U may be a power button, a play button, a stop button, a volume button, a setting button, etc.

[0116] The wireless communication interface 100W can perform communication with an external device. The external device can send and receive information and / or signals with the controller 100C of the speaker 100 through the wireless communication interface 100W. For example, the external device can be the display 10. The wireless communication interface 100W can utilize Bluetooth (Bluetooth TM ), RFID (Radio Frequency Identification), infrared communication (Infrared Data Association; IrDA), UWB (UltraWireband), ZigBee, NFC (Near Field Communication), Wi-Fi (Wireless-Fidelity), Wi-Fi Direct, and Wireless USB (Wireless Universal Serial Bus) technologies to perform wireless communication.

[0117] The display 10 may wirelessly transmit and receive information and / or signals with the speaker 100 via the wireless communication interface 100W.

[0118] Reference Fig.19 , the speaker 100 can transmit an IR (Infrared) Key to the display 10 (S10). The IR Key can be stored in the memory 100M of the speaker 100 (refer to Fig.18) code. For example, the IR Key value may be 0x1F. The controller 100C of the speaker 100 may transmit the IRKey to the display 10 through the IR (Infrared) circuit of the wireless communication interface 100W. If the display 10 receives the IR Key, the Bluetooth connection may be activated. That is, the IR Key may be a wake-up signal for the Bluetooth connection of the display 10.

[0119] For example, if the speaker 100 is powered on, the speaker 100 may transmit the IR Key to the display 10. As another example, if the user presses a button of the speaker 100, the speaker 100 may transmit the IR Key to the display 10. The button may be a button for triggering a Bluetooth connection between the speaker 100 and the display 10.

[0120] After S10, the speaker 100 may enter an advertising mode (S20). The advertising mode may be a mode for notifying surrounding devices of its own existence and whether it can be connected. The controller 100C of the speaker 100 may transmit an advertising signal to the surrounding devices, and the advertising signal may include identification information of the speaker 100. The identification information of the speaker 100 may include Bluetooth MAC (Media Access Control) address information, the name of the speaker 100, etc.

[0121] After S20, the display 10 may perform a search for peripheral devices (S30). The IR Key and the MAC address information and / or the name of the device corresponding to the IR Key may be stored in the memory M of the display 10 (refer to Fig.17 The IR Key of the speaker 100 and the MAC address information of the speaker 100 and / or the name of the device may be stored in the memory M of the display 10 (refer to Fig.17 ). The controller C of the display 10 may utilize the Bluetooth circuit of the wireless communication interface CI of the display 10 to search for the MAC address information and / or the speaker 100 with the name stored in the memory M.

[0122] If the search of the speaker 100 ends ( S40 : YES), the controller C of the display 10 may transmit a search end signal to the speaker 100 through the wireless communication interface CI, and the speaker 100 may end the advertisement mode ( S50 ).

[0123] Thus, the speaker 100 and the display 10 may perform Bluetooth pairing (S60). Bluetooth pairing may be a process in which the display 10 registers the speaker 100 for Bluetooth connection. The display 10 may store the Bluetooth MAC address and / or name of the speaker 100 in the memory M.

[0124] The controller C of the display 10 may transmit audio data to the speaker 100 through the Bluetooth circuit of the display 10 (S70), and the controller 100C of the speaker 100 may output audio based on the audio data received through the Bluetooth circuit of the speaker 100 (S80). Fig.17 ) can output the same as the speaker unit 100S of the speaker 100 (refer to Fig.18 ) the same audio. Alternatively, the speaker SPK of the display 10 and the speaker unit 100S of the speaker 100 may also constitute surround audio. The surround audio may be constituted by either the speaker SPK or the speaker 100 outputting the main audio and the other outputting the surrounding audio (e.g., background music).

[0125] This can improve the acoustic performance of the display device 1 including the display 10 and the speaker 100 .

[0126] Reference Fig. 20 , the controller 100C of the speaker 100 may determine whether there is a history of pairing the speaker 100 with the display 10 ( S1 ).

[0127] If there is no history of pairing the speaker 100 with the display 10 ( S1 : No), the controller 100C of the speaker 100 may perform an IR Key transmission sequence ( S10 ) to guide Bluetooth pairing of the speaker 100 with the display 10 .

[0128] If there is a history of pairing the speaker 100 with the display 10 (S1: Yes), the controller 100C of the speaker 100 may wait for the Bluetooth connection of the display 10 with the speaker 100 during a preset time t. If the display 10 and the speaker 100 are not Bluetooth paired within the preset time t, the controller 100C of the speaker 100 performs an IR Key transmission sequence (S10) to guide the Bluetooth pairing of the speaker 100 with the display 10. For example, the time t may be 10 seconds.

[0129] After S10 , the speaker 100 may be paired with the display 10 via Bluetooth ( S60 ).

[0130] On the other hand, if the speaker 100 is connected to a power cable or a charging cable (charger), even if the power of the speaker 100 is turned off, when the display 10 that is turned on requests a Bluetooth pairing connection with the speaker 100, the power of the speaker 100 can be turned on, and the IR Key will not be transmitted to the display 10. Here, even if the power of the speaker 100 is turned off, the Bluetooth circuit of the wireless communication interface 100W can be driven. Therefore, if the power of the display 10 is turned on, the Bluetooth pairing of the display 10 and the speaker 100 can be automatically performed.

[0131] Refer again Figure 5 and Fig.10 , a transmitter 100WR (Infrared Sender) outputting an IR Key may be disposed on the upper portion of the speaker 100. The IR transmitter 100WR of the speaker 100 may wirelessly communicate with the IR receiver 10WR of the display 10. The IR receiver 10WR may be disposed on one side (e.g., the bottom side) of the display 10. If the speaker 100 is mounted on the pole 30, the IR transmitter 100WR of the speaker 100 and the IR receiver 10WR of the display 10 may be disposed adjacent to each other.

[0132] In this way, the IR circuit of the speaker 100 and the IR circuit of the display 10 can be arranged relatively close to each other. In addition, the Bluetooth circuit of the speaker 100 and the Bluetooth circuit of the display 10 can also be arranged relatively close to each other.

[0133] Reference Fig.21 , the IR transmitter 100WR may be composed of a timer output and an interrupt service routine. The IR transmitter 100WR may have an IR circuit. For the formation of a remote control format, the timer setting may be used as a PWM (Pulse Width Modulation) output. The interrupt service routine may be used to count the timer output to output data matching the IR frame.

[0134] The IR module of the speaker 100 can use Timer2 to generate a 38kHz PWM output for IR Key transmission in a remote control format. In addition, the Timer0 counter can be set to output PWM during a specified time period. If an IR frame sequence begins, the IR transmitter 100WR can be used to transmit all data from the leading code to the command. In addition, the state machine can be configured so that the IR transmitter 100WR outputs data that matches the state of the rcSender (remote control Sender). Here, the state of the rcSender can change in sequence according to the configuration of the IR frame. When all data output is completed, the IR transmitter 100WR outputs a stop bit and the Timer also stops, thereby ending the IR Key transmission sequence.

[0135] As a first step of the IR Key transmission sequence execution ( S10 ), Timer0 counter setting and Timer2 timer setting ( S11 ) may be performed.

[0136] After S11, if the Timer0 counter is not 0 (S12: No), and the state of rcSender is in the first state (S13: Yes), the IR transmitter 100WR may output a leader code of the IR Key (S14). The leader code may be a code notifying the start of the IR Key transmission. After S14, Timer0 and Timer2 may be restarted (Restart) (S15), and may return to S12.

[0137] If the Timer0 counter is not 0 (S12: No), and the state of rcSender is the second state (S16: Yes), the IR transmitter 100WR can output the data bit (Data Bit) of the IR Key (S17). The data bit can be information containing instructions or data to be transmitted to the IR Key. After S17, Timer0 and Timer2 can be restarted (Restart) (S15) and can return to S12.

[0138] If the Timer0 counter is not 0 (S12: No), and the state of rcSender is the third state (S16: No), the IR transmitter 100WR may output a stop bit (S18). The stop bit may be a code notifying the end of the IR Key transmission. After S18, Timer0 and Timer2 may stop (S19).

[0139] If an IR Key is transmitted from the IR transmitter 100WR of the speaker 100 to the display 10, the Bluetooth circuit of the display 10 may be activated. The display 10 may search and register the speaker 100 that transmitted the IR Key, and pair the display 10 with the speaker 100 by Bluetooth.

[0140] Thus, even if the user does not take an action to activate the Bluetooth circuit of the display 10, Bluetooth pairing of the display 10 and the speaker 100 can be easily performed. The speaker 100 can output audio based on audio data received from the display 10 through the Bluetooth connection.
