One side of the elastic damper (100S6) may be coupled to the speaker frame (100S1), and the other side of the damper (100S6) may be coupled to the bobbin (100S4) and / or the diaphragm (100S5). One side of the elastic edge (100S7) may be coupled to the speaker frame (100S1), and the other side of the edge (100S7) may be coupled to the diaphragm (100S5).

[0091] When a magnetic field line is formed in the gap between the magnet (100S3) and the yoke (100S2) and a current flows through the coil of the bobbin (100S4), a Lorentz force may be generated. The magnitude of the Lorentz force may be proportional to the magnitude of the magnetic field line (magnetic flux density), the amount of current, and the length of the wound coil, and the direction of the force may be perpendicular to the plane formed by the magnetic flux density and the current. Accordingly, the diaphragm (100S5) may vibrate back and forth. In response to the vibration of the diaphragm (100S5), the air in the space between the frame (100F) and the bracket (100R) may also resonate, causing its pressure to change.

[0092] A plurality of speaker units (100S) may be arranged along the longitudinal direction of the frame (100F). The first speaker unit (100Sa) may be adjacent to one end (left end) of the frame (100F), and the second speaker unit (100Sb) may be adjacent to the other end (right end) of the frame (100F). For example, the first and second speaker units (100Sa, 100Sb) may be tweeters. The third speaker unit (100Sc) may be positioned at the center of the frame (100F). For example, the third speaker unit (100Sc) may be a woofer.

[0101] A straight section (1013) can connect the first curved section (1011) and the second curved section (1012). The straight section (1013) can extend along the straight upper side of the speaker (100).

[0102] Although light from a first light source (100Lb) is provided to one end (101a) of a lighting tube (101), the brightness of the lighting tube (101) may decrease as it moves away from the one end (101a). The brightness of a straight section (1013) may be lower than the brightness of a first curved section (1011). The brightness of a central portion of the straight section (1013) may be lower than the brightness of a portion of the straight section (1013) close to the first curved section (1011).

[0103] Although light from 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 decrease as it moves away from the other end (101b). The brightness of the straight section (1013) may be lower than the brightness of the second straight 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) that is closer to the second curved section (1012).

[0104] The optical sheet (102) may be positioned at the rear of 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 reflective sheet. The length of the optical sheet (102) may be shorter than the length of the lighting tube (101). One end (102a) of the optical sheet (102) may be positioned corresponding to a point of a first curved section (1011) of the lighting tube (101). The other end (102b) of the optical sheet (102) may be positioned corresponding to a point of a second curved section (1012) of the lighting tube (101). The optical sheet (102) may include a first curved section (1021), a second curved section (1022), and a straight section (1023).

[0105] The first curved section (1021) may form one end (102a) of the optical sheet (102) and may be curved. 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 (10111). A portion of the first portion (1011a) of the first curved section (1011) may not be covered by the optical sheet (102) because it is relatively close to the first light source (100Lb) and therefore relatively bright. The second portion (1011b) may not be covered by the optical sheet (102) because it is not only relatively bright because it is adjacent to the first light source (100Lb) but also curved inwardly of the frame (100F).

[0106] The second curved section (1022) may form the other end (102b) of the optical sheet (102) and may be curved. 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) may not be covered by the optical sheet (102) because it is relatively close to the second light source (100Rb) and therefore relatively bright. The second portion (1012b) may not be covered by the optical sheet (102) because it is not only relatively bright because it is adjacent to the second light source (100Rb) but also curved inwardly of the frame (100F).

[0107] A straight section (1023) can connect the first curved section (1021) and the second curved section (1022). The straight section (1023) can extend along the straight section (1013) of the lighting tube (101) and cover the rear of the straight section (1013).

[0108] Accordingly, the difference in brightness of light according to the distance from the light sources (100Lb, 100Rb) can be minimized. The difference in brightness of light can be minimized in the area corresponding to the optical sheet (102). The difference in brightness of light formed along the edge of the speaker (100) can be minimized.

[0109]

[0110] Referring to FIGS. 15 and 16, the lens (103) may be positioned in front of the lighting tube (101). The lens (103) may be opposite the optical sheet (102) with respect to the lighting tube (101). The lens (103) may be positioned between the rear case (108) and the front case (109). A portion of the lens (103) may form a portion of the outer surface 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 part (103a) and a second part (103b).

[0111] The first part (103a) may be positioned between the lighting tube (101) and the front case (109). The first part (103a) may be opposite the optical sheet (102) with respect to the lighting tube (101). The first part (103a) may extend along the edge of the frame (100F). The first part (103a) may be referred to as a horizontal portion (103a).

[0112] The second part (103b) may intersect the first part (103a) and may face the optical sheet (102). The second part (103b) may extend along the first part (103a) and cover the lighting tube (101). The second part (103b) may be positioned between the rear case (108) and the front case (109) and may form an edge of the speaker (100). The optical sheet (102) may be positioned between the second part (103b) and the rear case (108). The second part (103b) may be referred to as a vertical portion (103b). The frame (100F), the optical sheet (102), the first part (103a), and the second part (103b) may form a space in which the lighting tube (101) is positioned.

[0113] The third part (103c) may intersect with the first part (103a). The second part (103b) may be formed on one side (rear side) of the first part (103a) facing the optical sheet (102), and the third part (103c) may be formed on the other side (front side) of the first part (103a). The third part (103c) may face a portion of the inner surface of the front case (109).

[0114] Accordingly, the light guided by the lighting tube (101) and the optical sheet (102) as the light of the optical assembly (100A, see FIG. 13) can be illuminated to the outside through the lens (103). The difference in brightness at each point of the section of the lens (103) where light is emitted by the optical sheet (102) can be minimized. The color of the light emitted from the lens (103) can be varied. The light emitted from the lens (103) can be used to indicate the status of the speaker (100). For example, by adjusting the color, brightness, and whether or not the light emitted from the lens (103) blinks, various statuses of the speaker (100) can be indicated. The status of the speaker (100) can include whether the speaker (100) is powered on / off, the size of the volume, the beat of the sound being played, whether or not it is connected to the display (10) via Bluetooth, etc. The user can control whether or not the optical assembly (100A) operates.

[0115] Additionally, the lens (103) can block the gap between the rear case (108) and the front case (109).

[0116]

[0117] Referring to FIG. 17, the display (10) may include a display panel (11), boards (PSU, MB, TC), a built-in speaker (SPK), a user input interface (UI), a wireless communication interface (CI), and a memory (M).

A power source may provide power to the components of the display (10). For example, the power source may be a battery (Bt, see FIG. 1) of the display device (1).

[0118] The memory (M) can store programs, applications, data, etc. required for driving and controlling the display (10).

[0119] A user input interface (UI) can transmit signals input by a user to a controller (C). The display (10) can provide signals to a user or a user terminal through a user input interface (UI). For example, the user input interface (UI) may be a power button, a channel button, a volume button, a settings button, etc.

[0120] The wireless communication interface (CI) can communicate with an external device. The external device can transmit 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 be a Bluetooth TM), RFID (Radio Frequency Identification), Infrared Data Association (IrDA), UWB (Ultra Wireband), ZigBee, NFC (Near Field Communication), Wi-Fi (Wireless-Fidelity), Wi-Fi Direct, and Wireless USB (Wireless Universal Serial Bus) technologies can be used to perform wireless communication.

[0121] The remote control device (300) can wirelessly transmit and receive information and / or signals to and from the display (10) via a wireless communication interface (CI). The user can control the display (10) using the remote control device (300). For example, the user can use the remote control device (300) to turn the display (10) on / off, increase or decrease the volume, or change the channel.

[0122] The external speaker (100) can wirelessly transmit and receive information and / or signals with the display (10) via a wireless communication interface (CI).

[0123]

[0124] Referring to FIG. 18, the speaker (100) may include a speaker unit (100S), an optical assembly (100A), a user input interface (100U), a wireless communication interface (100W), and a memory (100M). The above 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, see FIG. 15) of the speaker (100). A power source may provide power to the 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).

[0125] The memory (100M) can store programs, applications, data, etc. required for driving and controlling the speaker (100).

[0126] The user input interface (100U) can transmit a signal input by the user to the controller (100C). The speaker (100) can provide a signal to the user or the user's terminal through the user input interface (100U). For example, the user input interface (100U) can be a power button, a play button, a stop button, a volume button, a settings button, etc.

[0127] The wireless communication interface (100W) can communicate with an external device. The external device can transmit 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 may be a display (10). The wireless communication interface (100W) may be a Bluetooth TM ), RFID (Radio Frequency Identification), Infrared Data Association (IrDA), UWB (Ultra Wireband), ZigBee, NFC (Near Field Communication), Wi-Fi (Wireless-Fidelity), Wi-Fi Direct, and Wireless USB (Wireless Universal Serial Bus) technologies can be used to perform wireless communication.

[0128] The display (10) can wirelessly transmit and receive information and / or signals to and from the speaker (100) via a wireless communication interface (100W).

[0129]

[0130] Referring to FIG. 19, the speaker (100) can transmit an IR (Infrared) Key (Key) to the display (10) (S10). The IR Key may be a code stored in the memory (100M, see FIG. 18) of the speaker (100). For example, the IR Key value may be 0x1F. The controller (100C) of the speaker (100) can transmit the IR Key to the display (10) through the IR (Infrared) circuit of the wireless communication interface (100W). When the display (10) receives the IR Key, a Bluetooth connection may be activated. That is, the IR Key may be a wake-up signal for the Bluetooth connection of the display (10).

[0131] For example, when the speaker (100) is turned on, the speaker (100) can transmit an IR Key to the display (10). As another example, when a user presses a button on the speaker (100), the speaker (100) can transmit an 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).

[0132] After S10, the speaker (100) may enter advertising mode (S20). Advertising mode may be a mode that informs peripheral devices of its presence and connection availability. The controller (100C) of the speaker (100) may transmit an advertising signal to the peripheral devices, and the advertising signal may include identification information of the speaker (100). The identification information of the speaker (100) may include Bluetooth MAC address information, the name of the speaker (100), etc.

[0133] After S20, the display (10) can search for peripheral devices (S30). The IR Key and the MAC address information of the device corresponding to the IR Key and / or the name of the device can be stored in the memory (M, see FIG. 17) of the display (10). The IR Key of the speaker (100) and the MAC address information of the speaker (100) and / or the name of the device can be stored in the memory (M, see FIG. 17) of the display (10). The controller (C) of the display (10) can search for the speaker (100) having the MAC address information and / or name stored in the memory (M) using the Bluetooth circuit of the wireless communication interface (CI) of the display (10).

[0134] When the search for the speaker (100) is completed (S40: Yes), the controller (C) of the display (10) can transmit a search completion signal to the speaker (100) through the wireless communication interface (CI), and the speaker (100) can exit the advertising mode (S50).

[0135] Accordingly, the speaker (100) and the display (10) can 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).

[0136] The controller (C) of the display (10) can transmit audio data to the speaker (100) via the Bluetooth circuit of the display (10) (S70), and the controller (100C) of the speaker (100) can output audio based on the audio data received via the Bluetooth circuit of the speaker (100) (S80). At this time, the speaker (SPK, see FIG. 17) of the display (10) can output the same audio as the speaker unit (100S, see FIG. 18) of the speaker (100). Alternatively, the speaker (SPK) of the display (10) and the speaker unit (100S) of the speaker (100) may configure surround audio. The surround audio may be configured such that either the speaker (SPK) or the speaker (100) outputs main audio, and the other outputs peripheral audio (e.g., background music).

[0137] Accordingly, the acoustic performance of a display device (1) having a display (10) and a speaker (100) can be improved.

[0138]

[0139] Referring to FIG. 20, the controller (100C) of the speaker (100) can determine whether there is a history of the speaker (100) being paired with the display (10) (S1).

[0140] If there is no history of the speaker (100) being paired with the display (10) (S1: No), the controller (100C) of the speaker (100) can induce Bluetooth pairing of the speaker (100) and the display (10) by executing an IR Key transmission sequence (S10).

[0141] If there is a history of the speaker (100) being paired with the display (10) (S1: Yes), the controller (100C) of the speaker (100) may wait for a Bluetooth connection between the display (10) and the speaker (100) for a certain period of time (t). If the display (10) and the speaker (100) are not paired with Bluetooth within the certain period of time (t), the controller (100C) of the speaker (100) may execute an IR Key transmission sequence (S10) to induce Bluetooth pairing between the speaker (100) and the display (10). For example, the period of time (t) may be 10 seconds.

[0142] After S10, the speaker (100) can be paired with the display (10) via Bluetooth (S60).

[0143] Meanwhile, if the speaker (100) is connected to a power cable or a charging cable (charger), even if the speaker (100) is turned off, if the display (10) that is turned on requests a Bluetooth pairing connection to the speaker (100), the speaker (100) may be turned on and may not transmit an IR Key to the display (10). Here, even if the speaker (100) is turned off, the Bluetooth circuit of the wireless communication interface (100W) may be driven. Accordingly, when the display (10) is turned on, Bluetooth pairing between the display (10) and the speaker (100) may be automatically performed.

[0144]

[0145] Referring again to FIGS. 5 and 10, an IR transmitter (100WR, Infrared Sender) for outputting an IR Key may be provided 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 provided on one side (e.g., the lower side) of the display (10). When 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 arranged adjacent to each other.

[0146] In this way, the IR circuit of the speaker (100) and the IR circuit of the display (10) can be placed relatively close together. In addition, the Bluetooth circuit of the speaker (100) and the Bluetooth circuit of the display (10) can also be placed relatively close together.

[0147]

[0148] Referring to Fig. 21, the IR transmitter (100WR) may be configured with a timer output and an interrupt service routine. The IR transmitter (100WR) may include an IR circuit. The timer setting may be used for PWM (Pulse Width Modulation) output to configure a remote control format. The interrupt service routine may be used to count the timer output and output data according to the IR frame.

[0149] The IR module of the speaker (100) can generate a 38kHz PWM output for IR Key transmission in a remote control format using Timer2. And, the Timer0 counter can be set to output PWM for a specified period of time. When one IR frame sequence starts, all data from a leading code to a command can be transmitted by the IR transmitter (100WR). And, the state machine (StateMachine) can be configured so that the IR transmitter (100WR) outputs data that matches the state of rcSender (remote control Sender). Here, the state of rcSender can change sequentially according to the configuration of the IR frame. When all data output is finished, the IR transmitter (100WR) can output a stop bit, and the Timer can also be stopped to terminate the IR Key transmission sequence.

[0150] As the first step of executing the IR Key transmission sequence (S10), Timer0 counter setting and Timer2 timer setting can be performed (S11).

[0151] After S11, if the Timer0 counter is not non-zero (S12: No) and the state of rcSender is the first state (S13: Yes), the IR transmitter (100WR) can output the leader code of the IR Key (S14). The leader code can be a code that indicates the start of IR Key transmission. After S14, Timer0 and Timer2 can be restarted (S15) and return to S12.

[0152] If the Timer0 counter is not non-zero (S12: No) and the state of rcSender is the second state (S16: Yes), the IR transmitter (100WR) can output the data bit of the IR Key (S17). The data bit can be information containing a command or data to be transmitted with the IR Key. After S17, Timer0 and Timer2 can be restarted (S15) and return to S12.

[0153] If the Timer0 counter is not non-zero (S12: No) and the state of rcSender is state 3 (S16: No), the IR transmitter (100WR) can output a stop bit (StopBit) (S18). The stop bit can be a code that signals the end of the IR Key transmission. After S18, Timer0 and Timer2 can be stopped (S19).
