The sound bar (30) can include a wireless communication module (32) for receiving sound sources from the external device (1) in a wireless manner.

[0065] Referring to FIG. 3, the sound bar (30) may include a housing (31) and a plurality of acoustic transducers (40C, 40FL, 40FR, 40SL, 40SR, 40TL, 40TR) provided on the inside of the housing (31).

[0066] The housing (31) may form the outer shape of the sound bar (30). For example, the housing (31) may be formed in a rectangular parallelepiped shape with a length that is longer than its thickness and width. The housing (31) may include a front surface (31a), a rear surface (31b), a left surface (31c), a right surface (31d), an upper surface (31e), and a lower surface (31f).

[0067] The sound bar (30) can be arranged in a generally horizontal direction when the lower surface (31f, see FIG. 2) of the housing (31) is in contact with the floor or the upper surface of a table on which the display device is placed. In the present disclosure, the sound bar (30) being arranged in a horizontal direction means being arranged in a non-specific direction. For example, the non-specific direction means a direction different from the first vertical direction and the second vertical direction.

[0068] FIG. 4 is an assembly diagram illustrating an audio device according to one or more embodiments of the present disclosure, wherein the sound bar is arranged in a first vertical direction. FIG. 5 is an assembly diagram illustrating an audio device according to one or more embodiments of the present disclosure, wherein the sound bar is arranged in a second vertical direction.

[0069] The sound bar (30) can be arranged vertically when the first end (30a) of the sound bar (30) or the second end (30b) on the opposite side of the first end (30a) is inserted into the joining groove (51) of the supporter (50).

[0070] When the sound bar (30) is arranged in a vertical direction, the sound bar (30) may be arranged in a first vertical direction or a second vertical direction. Referring to FIG. 4, when the first end (30a) of the sound bar (30) is inserted into the joining groove (51) of the supporter (50), the sound bar (30) is arranged in the first vertical direction. Referring to FIG. 5, when the second end (30b) of the sound bar (30) is inserted into the joining groove (51) of the supporter (50), the sound bar (30) is arranged in the second vertical direction.

[0071] The sound bar (30) can be configured to allocate different patterns of channel signals to a plurality of acoustic transducers (40C, 40FL, 40FR, 40SL, 40SR, 40TL, 40TR) based on the direction in which the sound bar (30) is placed (e.g., first vertical direction, second vertical direction, non-specific direction).

[0072] The plurality of acoustic transducers (40C, 40FL, 40FR, 40SL, 40SR, 40TL, 40TR) may include a first acoustic transducer (40C), a second acoustic transducer (40FL), a third acoustic transducer (40FR), a fourth acoustic transducer (40SL), a fifth acoustic transducer (40SR), a sixth acoustic transducer (40TL), and a seventh acoustic transducer (40TR).

[0073] The first acoustic transducer (40C), the second acoustic transducer (40FL), and the third acoustic transducer (40FR) may be arranged along the inner side of the front surface (31a) of the housing (31). For example, the first acoustic transducer (40C) may be arranged in the center of the front surface (31a) of the housing (31). The second acoustic transducer (40FL) may be arranged on the left side of the front surface (31a) of the housing (31). The third acoustic transducer (40FR) may be arranged on the right side of the front surface (31a) of the housing (31). Each of the first acoustic transducer (40C), the second acoustic transducer (40FL), and the third acoustic transducer (40FR) may include, but is not limited to, a plurality of acoustic transducers that reproduce mid-range frequencies (e.g., 200 Hz to 2000 Hz) and one tweeter that is an acoustic transducer that reproduces high-range frequencies (e.g., 2000 Hz to 20000 Hz). For example, each of the first acoustic transducer (40C), the second acoustic transducer (40FL), and the third acoustic transducer (40FR) may be composed of one acoustic transducer.

[0074] The fourth acoustic transducer (40SL) may be arranged on the inside of the left side (31c) of the housing (31). The fifth acoustic transducer (40SR) may be arranged on the inside of the right side (31d, see FIG. 2) of the housing (31). Each of the fourth acoustic transducer (40SL) and the fifth acoustic transducer (40SR) may be composed of one acoustic transducer, but is not limited thereto. For example, when the areas of the left side (31c) and the right side (31d) of the housing (31) are widened so that a plurality of acoustic transducers can be arranged on the left side (31c) and the right side (31d) of the housing (31), respectively, each of the fourth acoustic transducer (40SL) and the fifth acoustic transducer (40SR) may be composed of a plurality of acoustic transducers.

[0075] The sixth acoustic transducer (40 TL) and the seventh acoustic transducer (40 TR) may be arranged along the inner side of the upper surface (31e) of the housing (31). For example, the sixth acoustic transducer (40 TL) may be arranged on the left side of the upper surface of the housing (31). The seventh acoustic transducer (40 TR) may be arranged on the right side of the upper surface of the housing (31). Each of the sixth acoustic transducer (40 TL) and the seventh acoustic transducer (40 TR) may be composed of one acoustic transducer, but is not limited thereto. For example, each of the sixth acoustic transducer (40 TL) and the seventh acoustic transducer (40 TR) may be composed of a plurality of acoustic transducers.

[0076] The sound bar (30) may omit the fourth acoustic transducer (40SL), the fifth acoustic transducer (40SR), the sixth acoustic transducer (40TL), and the seventh acoustic transducer (TS), and may include the first acoustic transducer (40C), the second acoustic transducer (40FL), and the third acoustic transducer (40FR). Alternatively, the sound bar (30) may omit the sixth acoustic transducer (40TL) and the seventh acoustic transducer (TS), and may include the first acoustic transducer (40C), the second acoustic transducer (40FL), the third acoustic transducer (40FR), the fourth acoustic transducer (40SL), and the fifth acoustic transducer (40SR).

[0077] The housing (31) may be provided with a plurality of sound output holes (35a, 35b, 35c, 35d, 35e, 35f, 35g) on ​​the front (31a), left side (31c), right side (31d), and upper side (31e), respectively. For example, the front side (31a) of the housing (31) may be provided with a first sound output hole (35a), a second sound output hole (35b), and a third sound output hole (35c) corresponding to the first sound transducer (40C), the second sound transducer (40FL), and the third sound transducer (40FR), respectively. The left side (31c) of the housing (31) may be provided with a fourth sound output hole (35d) corresponding to the fourth sound transducer (40SL). A fifth sound output hole (35e) corresponding to a fifth sound transducer (40SR) may be provided on a right side (31d) of the housing (31). A sixth sound output hole (35f) and a seventh sound output hole (35g) corresponding to a sixth sound transducer (40TL) and a seventh sound transducer (40TR) may be provided on an upper side (31e) of the housing (31), respectively. A mesh cover that does not substantially interfere with sounds output from a plurality of sound transducers (40C, 40FL, 40FR, 40SL, 40SR, 40TL, 40TR) may be coupled to each of the first, second, third, fourth, fifth, sixth, and seventh sound output holes (35a, 35b, 35c, 35d, 35e, 35f, 35g).

[0078] Referring to FIG. 4, the supporter (50) may include a coupling groove (51) in the upper portion into which the first end (30a) or the second end (30b) of the sound bar (30) is detachably inserted. The coupling groove (51) of the supporter (50) may have a shape that roughly corresponds to the shapes of the first end (30a) and the second end (30b) of the sound bar (30). In the present disclosure, the first end (30a) of the sound bar (30) is used in a substantially identical sense to the first end of the housing (31). The second end (30b) of the sound bar (30) is used in a substantially identical sense to the second end of the housing (31).

[0079] The joining groove (51) of the supporter (50) may be configured to have a predetermined depth (h, see FIG. 6) in the direction in which the first end (30a) or the second end (30b) of the sound bar (30) is inserted so that the sound bar (30) is not easily separated. For example, the depth (h) of the joining groove (51) of the supporter (50) may be configured to such an extent that the first end (30a) or the second end (30b) of the sound bar (30) is not separated from the joining groove (51) of the supporter (50) when an external impact is applied to the sound bar (30) or the supporter (50).

[0080] Fig. 6 is a front view illustrating a supporter of an audio device according to one or more embodiments of the present disclosure. Fig. 7 is a cross-sectional view taken along line A-A' shown in Fig. 6.

[0081] When the first end (30a) of the sound bar (30) is inserted into the joining groove (51) of the supporter (50) (see FIG. 4), among the plurality of second acoustic transducers (40FL) of the sound bar (30), the second acoustic transducer (40FL) adjacent to the left side (31c) of the housing (31) can be positioned within the joining groove (51) of the supporter (50). In this case, the total sound output amount output from the plurality of second acoustic transducers (40FL) of the sound bar (30) can be reduced. The opening (53) of the supporter (50) can improve the reduction in the total sound output amount output from the plurality of second acoustic transducers (40FL) by preventing the second acoustic transducer (40FL) adjacent to the left side (31c) of the housing (31) from being covered by the joining groove (51) of the supporter (50).

[0082] Referring to FIGS. 6 and 7, the opening (53) of the supporter (50) can be connected to the joining groove (51) through a through hole (51a) provided on one side of the joining groove (51) of the supporter (50). The opening (53) of the supporter (50) can be formed to be inclined toward the lower portion of the supporter (50) and gradually widen toward the left and right sides of the supporter (50). The opening (53) of the supporter (50) can include a central inclined surface (53a), and a left inclined surface (53b) and a right inclined surface (53c) that are arranged symmetrically to the left and right of the central inclined surface (53a).

[0083] The opening (53) of the supporter (50) can expose the second acoustic transducer (40FL) adjacent to the left side (31c) of the housing (31) to the outside of the supporter (50). Since the sound output from the second acoustic transducer (40FL) is smoothly output to the outside of the supporter (50) by the opening (53) of the supporter (50) adjacent to the left side (31c) of the housing (31), the reduction in the overall sound output from the plurality of second acoustic transducers (40FL) of the sound bar (30) can be improved.

[0084] FIG. 8 is a block diagram illustrating an audio device (10) according to one or more embodiments of the present disclosure.

[0085] The audio device (10) may include a sensor (33) that detects the placement direction of the sound bar (30), an audio signal processing module (81) that transmits a channel signal to a plurality of acoustic transducers (40C, 40FL, 40FR, 40SL, 40SR, 40TL, 40TR), a memory (91) that stores instructions, and a processor (93) that executes the instructions.

[0086] The sensor (33) can obtain a sensing value corresponding to the arrangement direction of the sound bar (30). For example, when the sound bar (30) is arranged in a first vertical orientation, the sensor (33) can obtain a sensing value corresponding to the first vertical orientation. When the sound bar (30) is arranged in a second vertical orientation, the sensor (33) can obtain a sensing value corresponding to the second vertical orientation. When the sound bar (30) is arranged in a non-specified orientation, the sensor (33) can obtain a sensing value corresponding to the non-specified orientation.

[0087] Here, the 'first vertical direction' means the arrangement direction of the sound bar (30) when the first end (30a) of the sound bar (30) is inserted into the joining groove (51) of the supporter (50). The 'second vertical direction' means the arrangement direction of the sound bar (30) when the second end (30b) of the sound bar (30) is inserted into the joining groove (51) of the supporter (50). The 'non-specific direction' means a direction different from the first vertical direction and the second vertical direction. When the lower surface (31f) of the sound bar (30) is placed on the floor or the top surface of a table, the sound bar (30) can be arranged in a roughly horizontal orientation, in which case the horizontal direction can be included in the non-specific direction.

[0088] The sensor (33) may be, for example, a magnetic switch sensor. The sensor (33) may include a first reed switch (33a, see FIG. 2) and a second reed switch (33b, see FIGS. 2 and 3) provided in the sound bar (30), and a magnet (33c, see FIG. 7) provided in the coupling groove (51) of the supporter (50).

[0089] The first reed switch (33a) may be located at the first end (30a) of the sound bar (30). The first reed switch (33a) may be placed inside the housing (31). In this case, the first reed switch (33a) may be placed adjacent to the rear surface (31b) of the housing (31) inside the housing (31).

[0090] The first reed switch (33a) can be positioned at a position corresponding to the magnet (33c) provided in the coupling groove (51) of the supporter (50) when the first end (30a) of the sound bar (30) is inserted into the coupling groove (51) of the supporter (50). The first reed switch (33a) reacts to the magnetic force of the magnet (33c) and changes from an off state to an on state. When the processor (93) identifies the first reed switch (33a) as being in the on state, the processor (93) can identify that the sound bar (30) is arranged in the first vertical direction. The processor (93) can execute an instruction corresponding to the first vertical direction arrangement of the sound bar (30).

[0091] The second reed switch (33b) may be located at the second end (30b) of the sound bar (30). The second reed switch (33b) may be placed inside the housing (31). In this case, the second reed switch (33b) may be placed adjacent to the rear surface (31b) of the housing (31) inside the housing (31).

[0092] The second reed switch (33b) can be positioned at a position corresponding to the magnet (33c) provided in the coupling groove (51) of the supporter (50) when the second end (30b) of the sound bar (30) is inserted into the coupling groove (51) of the supporter (50). The second reed switch (33b) changes from an off state to an on state in response to the magnetic force of the magnet (33c). When the second reed switch (33b) is identified as being in the on state, the processor (93) can identify that the sound bar (30) is arranged in the second vertical direction. The processor (93) can execute an instruction corresponding to the second vertical direction arrangement of the sound bar (30).

[0093] When the first end (30a) of the sound bar (30) is separated from the coupling groove (51) of the supporter (50), the first reed switch (33a) is separated from the magnet (33c) and is turned off. When the second end (30b) of the sound bar (30) is separated from the coupling groove (51) of the supporter (50), the second reed switch (33b) is separated from the magnet (33c) and is turned off.

[0094] If neither the first end (30a) nor the second end (30b) of the sound bar (30) is inserted into the coupling groove (51) of the supporter (50), both the first reed switch (33a) and the second lease switch (33b) are turned off. If the processor (93) identifies that both the first reed switch (33a) and the second lease switch (33b) are turned off, the processor (93) can identify that the sound bar (30) is arranged in a non-specific direction. The processor (93) can execute an instruction corresponding to the non-specific direction arrangement of the sound bar (30).

[0095] The audio signal processing module (81) can convert an electrical signal into sound. The audio signal processing module (81) can assign multiple channel signals included in a sound source acquired from an external device (1) to multiple acoustic transducers (40C, 40FL, 40FR, 40SL, 40SR, 40TL, 40TR).

[0096] The audio signal processing module (81) can transmit a front center channel signal included in the sound source to the first sound transducer (40C). The audio signal processing module (81) can transmit a front left channel signal included in the sound source to the second sound transducer (40FL). The audio signal processing module (81) can transmit a front right channel signal included in the sound source to the third sound transducer (40FR). For example, when the front center channel signal, the front left channel signal, and the front right channel signal are allocated to the first sound transducer (40C), the second sound transducer (40FL), and the third sound transducer (40FR) by the audio signal processing module (81), the audio device (10) can output sounds from the first sound transducer (40C), the second sound transducer (40FL), and the third sound transducer (40FR), respectively, to implement stereo sound.

[0097] The audio signal processing module (81) can transmit a side left channel signal included in the sound source to the fourth sound transducer (40SL). The audio signal processing module (81) can transmit a side right channel signal included in the sound source to the fifth sound transducer (40SR). For example, when a front center channel signal, a front left channel signal, a front right channel signal, a side left channel signal, and a side right channel signal are allocated to a first sound transducer (40C), a second sound transducer (40FL), a third sound transducer (40FR), a fourth sound transducer (40SL), and a fifth sound transducer (40SR), respectively, by an audio signal processing module (81), the audio device (10) can output sounds from each of the first sound transducer (40C), the second sound transducer (40FL), the third sound transducer (40FR), the fourth sound transducer (40SL), and the fifth sound transducer (40SR), thereby implementing surround sound.

[0098] The audio signal processing module (81) can transmit the upper left channel signal included in the sound source to the sixth acoustic transducer (40TL). The audio signal processing module (81) can transmit the upper right channel signal included in the sound source to the seventh acoustic transducer (40TR). For example, when the front center channel signal, the front left channel signal, the front right channel signal, the side left channel signal, the side right channel signal, the top left channel signal, and the top right channel signal are allocated to the first sound transducer (40C), the second sound transducer (40FL), the third sound transducer (40FR), the fourth sound transducer (40SL), the fifth sound transducer (40SR), the sixth sound transducer (40TL), and the seventh sound transducer (40TR) respectively by the audio signal processing module (81), the audio device (10) outputs sound from the first sound transducer (40C), the second sound transducer (40FL), the third sound transducer (40FR), the fourth sound transducer (40SL), the fifth sound transducer (40SR), the sixth sound transducer (40TL), and the seventh sound transducer (40TR) respectively to provide Dolby Atmos TM ) can implement sound.

[0099] The audio signal processing module (81) can transmit a mono channel signal to a plurality of acoustic transducers (40C, 40FL, 40FR, 40SL, 40SR, 40TL, 40TR).

[0100] The memory (91) can store various data used by at least one component (e.g., sensor (33), audio signal processing module (81), or processor (93)) of the audio device (10). The data can include, for example, instructions for assigning various patterns of channel signals to a plurality of acoustic transducers (40C, 40FL, 40FR, 40SL, 40SR, 40TL, 40TR) based on the orientation of the sound bar (30). The memory (91) can include volatile memory or non-volatile memory.

[0101] The processor (93) may be configured to control the sensor (33), audio signal processing module (81), and memory (91).

[0102] The processor (93) can identify the direction of the sound bar (30) by receiving the sensing value transmitted from the sensor (33). The processor (93) can execute instructions stored in the memory (91) based on the direction in which the sound bar (30) is placed. The processor (93) can execute instructions to transmit channel signals of various patterns to a plurality of acoustic transducers (40C, 40FL, 40FR, 40SL, 40SR, 40TL, 40TR) through the audio signal processing module (81) based on the direction of the sound bar (30) identified by the sensor (33).

[0103] The processor (93) can execute an instruction that causes the audio signal processing module (81) to transmit channel signals of various patterns to a plurality of acoustic transducers (40C, 40FL, 40FR, 40SL, 40SR, 40TL, 40TR) or to synthesize a plurality of channel signals and transmit them to a plurality of acoustic transducers (40C, 40FL, 40FR, 40SL, 40SR, 40TL, 40TR).

[0104] For example, when the direction of the sound bar (30) is identified by the sensor (33) as the first vertical direction (see FIG. 4), the processor (93) may execute an instruction to cause the audio signal processing module (81) to transmit a mono channel signal to each of the plurality of acoustic transducers (40C, 40FL, 40FR, 40SL, 40SR, 40TL, 40TR).

[0105] For example, when the direction of the sound bar (30) is identified as the first vertical direction by the sensor (33), the processor (93) may execute an instruction causing the audio signal processing module (81) to transmit a front center channel signal to each of the first, second, third, fourth, and fifth sound transducers (40C, 40FL, 40FR, 40SL, 40SR), and to transmit a front left channel signal or a side left channel signal to each of the sixth and seventh sound transducers (40TL, 40TR).

[0106] For example, when the direction of the sound bar (30) is identified as the first vertical direction by the sensor (33), the processor (93) may execute an instruction causing the audio signal processing module (81) to transmit a front left channel signal or a side left channel signal to each of the first, second, third, fourth, and fifth acoustic transducers (40C, 40FL, 40FR, 40SL, 40SR).

[0107] For example, when the direction of the sound bar (30) is identified as the first vertical direction by the sensor (33), the processor (93) may execute an instruction causing the audio signal processing module (81) to synthesize and transmit a front right channel signal and a front center channel signal to each of the first, second, third, fourth, and fifth sound transducers (40C, 40FL, 40FR, 40SL, 40SR), and to synthesize and transmit a front left channel signal or a side center channel signal to each of the sixth and seventh sound transducers (40TL, 40TR).

[0108] For example, if the direction of the sound bar (30) is identified as the first vertical direction by the sensor (33), the processor (93) may execute an instruction causing the audio signal processing module (81) to transmit a front center channel signal to each of the first, second, third, and fifth acoustic transducers (40C, 40FL, 40FR, 40SR), and to transmit a front left channel signal or a side left channel signal to each of the sixth and seventh acoustic transducers (40TL, 40TR). The processor (93) may be configured not to transmit any channel signal to the fourth acoustic transducer (40SL). Accordingly, the fourth acoustic transducer (40SL) does not output sound. This is in consideration of the fact that if a separate opening is not formed at the bottom of the joining groove (51) of the supporter (50), even if sound is output from the fourth acoustic transducer (40SL), it is not transmitted to the outside of the supporter (50).

[0109] For example, when the direction of the sound bar (30) is identified by the sensor (33) as the second vertical direction (see FIG. 8), the processor (93) may execute an instruction to cause the audio signal processing module (81) to transmit a mono channel signal to each of the plurality of acoustic transducers (40C, 40FL, 40FR, 40SL, 40SR, 40TL, 40TR).

[0110] For example, when the direction of the sound bar (30) is identified as the second vertical direction by the sensor (33), the processor (93) may execute an instruction causing the audio signal processing module (81) to transmit a front center channel signal to each of the first, second, third, fourth, and fifth sound transducers (40C, 40FL, 40FR, 40SL, 40SR), and to transmit a front right channel signal or a side right channel signal to each of the sixth and seventh sound transducers (40TL, 40TR).

[0111] For example, when the direction of the sound bar (30) is identified as the second vertical direction by the sensor (33), the processor (93) may execute an instruction causing the audio signal processing module (81) to transmit a front right channel signal or a side right channel signal to each of the first, second, third, fourth, and fifth acoustic transducers (40C, 40FL, 40FR, 40SL, 40SR).

[0112] For example, when the direction of the sound bar (30) is identified as the second vertical direction by the sensor (33), the processor (93) may execute an instruction causing the audio signal processing module (81) to synthesize and transmit a front left channel signal and a front center channel signal to each of the first, second, third, fourth, and fifth sound transducers (40C, 40FL, 40FR, 40SL, 40SR), and to synthesize and transmit a front right channel signal or a side center channel signal to each of the sixth and seventh sound transducers (40TL, 40TR).

[0113] For example, the processor (93) may execute an instruction to cause the audio signal processing module (81) to transmit a front center channel signal to each of the first, second, third, and fourth sound transducers (40C, 40FL, 40FR, 40SL), and to transmit a front right channel signal or a side right channel signal to each of the sixth and seventh sound transducers (40TL, 40TR), when the direction of the sound bar (30) is identified as the second vertical direction by the sensor (33).

[0114] The processor (93) may be configured not to transmit any channel signal to the fifth acoustic transducer (40SR). Accordingly, the fifth acoustic transducer (40SR) does not output sound. This is in consideration of the fact that, if a separate opening is not formed at the bottom of the coupling groove (51) of the supporter (50), the sound output from the fifth acoustic transducer (40SR) is not transmitted to the outside of the supporter (50).

[0115] For example, if the direction of the sound bar (30) is identified by the sensor (33) as being arranged in a non-specific direction, the processor (93) may execute an instruction causing the audio signal processing module (81) to transmit a front center channel signal to the first acoustic transducer (40C), a front left channel signal to the second acoustic transducer (40FL), a front right channel signal to the third acoustic transducer (40FR), a side left channel signal to the fourth acoustic transducer (40SL), a side right channel signal to the fifth acoustic transducer (40SR), a top left channel signal to the sixth acoustic transducer (40TL), and a top right channel signal to the seventh acoustic transducer (40TR).

[0116] The channel signal that the processor (93) transmits to a plurality of acoustic transducers (40C, 40FL, 40FR, 40SL, 40SR, 40TL, 40TR) through the audio signal processing module (81) is not limited to the channel signals described above and can be configured to have various patterns.

[0117] The processor (93) may control at least one other component (e.g., hardware or software component) of the audio device (10) connected to the processor (93) by executing software (e.g., a program), and may perform various data processing or operations. The program may be stored as software in the memory (91) and may include, for example, an operating system (OS), middleware, or an application.

[0118] According to one embodiment, as at least part of data processing or calculation, the processor (93) may load instructions or data received from another component (e.g., a wireless communication module (32), a sensor (33), or an audio signal processing module (81)) into a volatile memory, process the instructions or data stored in the volatile memory, and store the resulting data in a non-volatile memory. According to one embodiment, the processor (93) may include a main processor (e.g., a central processing unit (CPU) or an application processor (AP)).

[0119] In the present disclosure, the sensor (33) for detecting the direction of the sound bar (30) is exemplified as a magnetic switch sensor, but is not limited thereto. For example, the sensor (33) may be configured as one of various types of sensors capable of detecting the direction of the sound bar (30). Hereinafter, with reference to the drawings, an example in which the sensor (33) is configured as an IMU (inertial measurement unit) or a push switch sensor will be described.

[0120] FIG. 9 is a diagram illustrating a sound bar of an audio device according to one or more embodiments of the present disclosure.

[0121] Referring to FIG. 9, a sensor (33-1) for detecting the direction of a sound bar (30-1) may be placed inside a housing (31-1). The sensor (33-1) may be an IMU having six degrees of freedom, including an acceleration sensor and an angular velocity sensor. The sensor (33-1) may be an IMU having nine degrees of freedom, including an acceleration sensor, an angular velocity sensor, and a geomagnetic sensor.

[0122] The sensor (33-1) is not limited to a specific location within the housing (31-1) and may be positioned in various locations. For example, the sensor (33-1) may be positioned anywhere within the housing (31-1), such as the first end (30a-1) of the sound bar (30-1), the second end (30b-1) of the sound bar (30-1), or the central portion of the sound bar (30). The sensor (33-1) can detect the tilted angle of the sound bar (30-1) and generate a signal corresponding to the angle.

[0123] For example, the sensor (33-1) can obtain a sensing value (e.g., a three-dimensional coordinate of the sound bar) corresponding to the first vertical direction of the sound bar (30-1) when the first end (30a-1) of the sound bar (30-1) is inserted into the joining groove (51) of the supporter (50) (see FIG. 4). The processor (93) identifies that the sound bar (30-1) is arranged in the first vertical direction based on the sensing value of the sensor (33-1). The processor (93) can execute an instruction corresponding to the first vertical direction arrangement of the sound bar (30-1).

[0124] For example, the sensor (33-1) can obtain a sensing value (e.g., a three-dimensional coordinate of the sound bar) corresponding to the second vertical direction of the sound bar (30-1) when the second end (30b-1) of the sound bar (30-1) is inserted into the joining groove (51) of the supporter (50) (see FIG. 5). The processor (93) identifies that the sound bar (30-1) is arranged in the second vertical direction based on the sensing value of the sensor (33-1). The processor (93) can execute an instruction corresponding to the second vertical direction arrangement of the sound bar (30-1).

[0125] For example, if neither the first end (30a-1) nor the second end (30b-1) of the sound bar (30-1) is inserted into the coupling groove (51) of the supporter (50), the sensor (33-1) can obtain a sensing value (e.g., a three-dimensional coordinate of the sound bar) corresponding to a non-specified orientation of the sound bar (30-1). The processor (93) identifies that the sound bar (30-1) is arranged in a non-specified orientation based on the sensing value of the sensor (33-1). The processor (93) can execute an instruction corresponding to the non-specified orientation arrangement of the sound bar (30-1).

[0126] FIG. 10 is a diagram illustrating an example of a sensor that detects the direction of a sound bar of an audio device according to one or more embodiments of the present disclosure.

[0127] Referring to Fig. 10, the sensor (33-2) may be, for example, a push switch sensor. The sensor (33-2) may include a first push switch (33a-2) provided at a first end (30a-2) of the sound bar (30-2) and a second push switch (33b-2) provided at a second end (30b-2) of the sound bar (30-2). For example, the first push switch (33a-2) may be arranged inside the housing (31-2). The first push switch (33a-2) may be configured such that a portion thereof protrudes from the left side (31c-2) of the housing (31-2).

[0128] A part of the first push switch (33a-2) is pressed against the bottom surface (51a-2) of the coupling groove (51) when the first end (30a-2) of the sound bar (30-2) is inserted into the coupling groove (51-2) of the supporter (50-2), thereby changing from an off state to an on state. When the first push switch (33a-2) is identified as being in the on state, the processor (93) can identify that the sound bar (30-2) is arranged in the first vertical direction. The processor (93) can execute an instruction corresponding to the first vertical direction arrangement of the sound bar (30-2).

[0129] A part of the second push switch (33b-2) is pressed against the bottom surface (51a-2) of the coupling groove (51) when the second end (30b-2) of the sound bar (30-2) is inserted into the coupling groove (51-2) of the supporter (50-2), thereby changing from the off state to the on state. When the second push switch (33b-2) is identified as being in the on state, the processor (93) can identify that the sound bar (30-2) is arranged in the second vertical direction. The processor (93) can execute an instruction corresponding to the second vertical direction arrangement of the sound bar (30-2).

[0130] FIG. 11 is an exploded view illustrating an example of an audio device (100) including a sound bar (130) and a subwoofer (150) as a supporter according to one or more embodiments of the present disclosure. FIG. 12 is an assembly diagram illustrating an example of an audio device (100) including a sound bar (130) and a subwoofer (150) as a supporter according to one or more embodiments of the present disclosure.

[0131] The audio device (100) may include a sound bar (130) and a subwoofer (150) as a supporter. The sound bar (130) may be configured substantially the same as the sound bar (30) illustrated in FIGS. 2 and 3. The subwoofer (150) may be capable of reproducing low-frequency sounds (e.g., below 100 Hz).

[0132] For example, the subwoofer (150) may include a wireless communication module (132) of the sound bar (130) and a wireless communication module (152) capable of wirelessly transmitting and receiving audio signals. The processor (93) may execute an instruction for the audio signal processing module (81) to transmit a channel signal to the acoustic transducer (154) of the subwoofer (150) through the wireless communication module (152) of the subwoofer (150).

[0133] For example, the subwoofer (150) can transmit and receive audio signals to and from the sound bar (130) via an audio cable. The processor (93) can execute an instruction for the audio signal processing module (81) to transmit a channel signal to the transducer (154) of the subwoofer (150) via the audio cable.

[0134] Referring to FIG. 11, the subwoofer (150) may include a coupling groove (151) in the upper portion into which the first end (130a) or the second end (130b) of the sound bar (130) is detachably inserted. The coupling groove (151) of the subwoofer (150) may have a shape that roughly corresponds to the shapes of the first end (130a) and the second end (130b) of the sound bar (130).

[0135] The opening (153) of the subwoofer (150) can be connected to the joining groove (151) through a through hole (151a) provided on one side of the joining groove (151) of the subwoofer (150). The opening (153) of the subwoofer (150) can be configured substantially the same as the opening (53) of the supporter (50) illustrated in FIGS. 6 and 7.

[0136] Referring to FIG. 12, the sound bar (130) can be arranged in the first vertical direction by inserting the first end (130a) of the sound bar (130) into the joining groove (151) of the subwoofer (150). In this case, the opening (153) of the subwoofer (150) does not cover the second sound transducer (140FL) adjacent to the left side (131c) of the housing (131) due to the joining groove (151) of the subwoofer (150). Therefore, the opening (153) of the subwoofer (150) can improve the reduction in the total sound output amount output from the plurality of second sound transducers (140FL).

[0137] The sound bar (130) can be arranged in the second vertical direction by inserting the second end (130b) of the sound bar (130) into the joining groove (151) of the subwoofer (150). In this case, the third sound transducer (140FR) adjacent to the right side (131c) of the housing (131) can be exposed to the outside (outside of the subwoofer (150)) by the opening (153) of the subwoofer (150). Therefore, the reduction in the total sound output from the plurality of second sound transducers (140FL) can be improved.

[0138] FIG. 13 is an assembly diagram illustrating an example of an audio device (100-1) including a sound bar (130-1) and a subwoofer (150-1) as a supporter according to one or more embodiments of the present disclosure. FIG. 14 is a plan view illustrating a subwoofer (150-1) of an audio device (100-1) according to one or more embodiments of the present disclosure. FIG. 15 is a cross-sectional view taken along the line B-B' shown in FIG. 14.

[0139] Referring to FIG. 13, the audio device (100-1) may include a sound bar (130) and a subwoofer (150) as a supporter. The sound bar (130-1) may be configured substantially the same as the sound bar (30) illustrated in FIGS. 2 and 3. The subwoofer (150-1) is largely the same as the subwoofer (150) illustrated in FIGS. 11 and 12, and may further include a first waveguide (156-1). Hereinafter, the structure of the subwoofer (150-1) will be described.

[0140] Referring to FIGS. 14 and 15, the subwoofer (150-1) may include a coupling groove (151-1) provided at the top, an opening (153-1) connected to one side of the coupling groove (151-1), and a first waveguide (156-1) connected to the bottom of the coupling groove (151-1).

[0141] A through hole (151b-1) may be formed at the bottom of the joining groove (151-1) of the subwoofer (150-1). A first sound radiation hole (157-1) may be provided at the front of the subwoofer (150-1). The first sound radiation hole (157-1) may be positioned at a predetermined distance below the opening (153-1). The first waveguide (156-1) may be provided to have a predetermined length along the inside of the subwoofer (150-1). One end of the first waveguide (156-1) may be connected to the through hole (151b-1) of the joining groove (151-1) and the other end may be connected to the first sound radiation hole (157-1).

[0142] When the first end (130a-1) of the sound bar (130-1) is inserted into the coupling groove (151-1) of the subwoofer (150-1), the fourth sound transducer (140SL-1) adjacent to the left side (131c-1) of the sound bar (130-1) faces the through hole (151b-1) of the coupling groove (151-1). In this case, the sound output from the fourth sound transducer (140SL-1) can travel along the first waveguide (156-1) and be radiated to the front of the subwoofer (150-1) through the first sound radiation hole (157-1). In addition, when the second end (130b-1) of the sound bar (130-1) is inserted into the joining groove (151-1) of the subwoofer (150-1), sound output from the fifth acoustic transducer (140SR-1) adjacent to the right side (131d-1) of the sound bar (130-1) can be radiated toward the front of the subwoofer (150-1) through the first waveguide (156-1) and the first sound radiation hole (157-1).

[0143] In this way, the audio device (100-1) can provide rich sound by additionally utilizing the sound output from the fourth acoustic transducer (140SL) of the sound bar (130-1) by adding the first waveguide (156-1) to the subwoofer (150-1).

[0144] FIG. 16 is an assembly diagram illustrating an example of an audio device (100-2) including a sound bar (130-2) and a subwoofer (150-2) as a supporter according to one or more embodiments of the present disclosure. FIG. 17 is a plan view illustrating a subwoofer (150-2) of an audio device (100-2) according to one or more embodiments of the present disclosure. FIG. 18 is a cross-sectional view taken along the line C-C' shown in FIG. 17.

[0145] Referring to FIG. 16, the audio device (100-2) may include a sound bar (130-2) and a subwoofer (150-2) as a supporter. The sound bar (130-2) may be configured substantially the same as the sound bar (30) illustrated in FIGS. 2 and 3. The subwoofer (150-2) is largely the same as the subwoofer (150) illustrated in FIGS. 11 and 12, and may further include a second waveguide (156a-2) and a third waveguide (156c-2). Hereinafter, the structure of the subwoofer (150-2) will be described.

[0146] Referring to FIGS. 17 and 18, the subwoofer (150-2) may include a coupling groove (151-2) provided at the top, an opening (153-2) connected to one side of the coupling groove (151-2), and a second waveguide (156a-2) and a third waveguide (156b-2) provided inside the subwoofer (150-2).

[0147] A through hole (151b-2) may be formed at the bottom of the joining groove (151-2) of the subwoofer (150-2). A second sound radiation hole (157a-2) and a third sound radiation hole (157b-2) may be provided on the left and right sides of the subwoofer (150-2), respectively. One end of the second waveguide (156a-2) may be connected to the through hole (151b-2) of the joining groove (151-2), and the other end may be connected to the second sound radiation hole (157a-2). One end of the third waveguide (156b-2) may be connected to the through hole (151b-2) of the joining groove (151-2), and the other end may be connected to the third sound radiation hole (157b-2). In this case, the second waveguide (156a-2) and the third waveguide (156b-2) can be interconnected.

[0148] When the first end (130a-2) of the sound bar (130-2) is inserted into the coupling groove (151-2) of the subwoofer (150-2), the fourth sound transducer (140SL-2) adjacent to the left side (131c-2) of the sound bar (130-2) faces the through hole (151b-2) of the coupling groove (151-2). In this case, the sound output from the fourth sound transducer (140SL-2) travels along the second waveguide (156a-2) and the third waveguide (156b-2). Sound passing through the third waveguide (156a-2) can be radiated to the left side of the subwoofer (150-2) through the second sound radiation hole (157a-2), and sound passing through the third waveguide (156b-2) can be radiated to the right side of the subwoofer (150-2) through the third sound radiation hole (157b-2).

[0149] In this way, the audio device (100-2) can provide a sense of space by radiating the sound output from the fourth acoustic transducer (140SL-1) of the sound bar (130-1) to the left and right sides of the subwoofer (150-2) by adding the second waveguide (156a-2) and the third waveguide (156b-2) to the subwoofer (150-2).

[0150] When the second end (130b-2) of the sound bar (130-2) is inserted into the joining groove (151-2) of the subwoofer (150-2), the sound output from the fourth acoustic transducer (140SR-2) adjacent to the right side (131d-2) of the sound bar (130-2) can be radiated to the left and right sides of the subwoofer (150-2), respectively.

[0151] According to one embodiment, the subwoofer (150-2) may be equipped with only one waveguide among the second waveguide (156a-2) and the third waveguide (156b-2). In this case, the sound output from the fourth acoustic transducer (140SL-2) or the fifth acoustic transducer (140SR-2) adjacent to the left side (131c-2) of the sound bar (130-2) may be radiated only to the left side or only to the right side of the subwoofer (150-2).

[0152] FIG. 19 is an assembly diagram showing an example of an audio device (100-3) including a sound bar (130-3) and a subwoofer (150-3) as a supporter according to one or more embodiments of the present disclosure. FIG. 20 is a front view showing a subwoofer (150-3) of an audio device (100-3) according to one or more embodiments of the present disclosure. FIG. 21 is a cross-sectional view taken along the line D-D' shown in FIG. 20. FIG. 22 is a cross-sectional view taken along the line E-E' shown in FIG. 20.

[0153] Referring to FIG. 19, the audio device (100-3) may include a sound bar (130-3) and a subwoofer (150-3) as a supporter. The sound bar (130-3) may be configured substantially the same as the sound bar (30) illustrated in FIGS. 2 and 3. The subwoofer (150-3) is largely the same as the subwoofer (150) illustrated in FIGS. 11 and 12, and may further include a fourth waveguide (156a-3), a fourth waveguide (156b-3), and a fifth waveguide (156c-3). Hereinafter, the structure of the subwoofer (150-3) will be described.

[0154] Referring to FIGS. 20, 21 and 22, the subwoofer (150-3) may include a coupling groove (151-3) provided at the top, an opening (153-3) connected to one side of the coupling groove (151-3), and a fourth waveguide (156a-3), a fifth waveguide (156b-3) and a sixth waveguide (156c-3) provided inside the subwoofer (150-3).

[0155] A through hole (151b-2) may be formed at the bottom of the joining groove (151-2) of the subwoofer (150-2). A fourth sound radiation hole (157a-3), a fifth sound radiation hole (157b-3), and a sixth sound radiation hole (157c-3) may be provided on the front, left side, and right side of the subwoofer (150-2), respectively. The fourth waveguide (156a-3) may have one end connected to the through hole (151b-3) of the joining groove (151-3) and the other end connected to the fourth sound radiation hole (157a-3). The fifth waveguide (156b-3) may have one end connected to the through hole (151b-3) of the joining groove (151-3) and the other end connected to the fifth sound radiation hole (157b-3). The sixth waveguide (156c-3) may have one end connected to the through hole (151b-3) of the coupling groove (151-3) and the other end connected to the sixth sound radiation hole (157c-3). In this case, the fourth waveguide (156a-3), the fifth waveguide (156b-3), and the sixth waveguide (156b-2) may be interconnected.

[0156] When the first end (130a-3) of the sound bar (130-3) is inserted into the coupling groove (151-3) of the subwoofer (150-3), the fourth sound transducer (140SL-3) adjacent to the left side (131c-3) of the sound bar (130-3) faces the through hole (151b-3) of the coupling groove (151-3). In this case, the sound output from the fourth sound transducer (140SL-3) travels along the fourth, fifth, and sixth waveguides (156a-3, 156b-3, 156c-3). Sound passing through the fourth waveguide (156a-3) can be radiated to the front of the subwoofer (150-3) through the third sound radiation hole (157a-3), sound passing through the fifth waveguide (156b-3) can be radiated to the left of the subwoofer (150-3) through the fifth sound radiation hole (157b-3), and sound passing through the sixth waveguide (156c-3) can be radiated to the right of the subwoofer (150-3) through the sixth sound radiation hole (157c-3).

[0157] In this way, the audio device (100-2) can provide a three-dimensional effect by radiating the sound output from the fourth acoustic transducer (140SL-1) of the sound bar (130-1) in three directions (front, left, and right) of the subwoofer (150-2) by adding a second waveguide (156a-2) and a third waveguide (156b-2) to the subwoofer (150-2).

[0158] When the second end (130b-3) of the sound bar (130-3) is inserted into the joining groove (151-3) of the subwoofer (150-3), the sound output from the fourth acoustic transducer (140SR-3) adjacent to the right side (131d-3) of the sound bar (130-3) can be radiated to the front, left, and right sides of the subwoofer (150-2), respectively.

[0159] FIG. 23 is an exploded view illustrating an example of an audio device (100-4) including a sound bar (130-4) and a subwoofer (150-4) as a supporter according to one or more embodiments of the present disclosure. FIG. 24 is a diagram illustrating a rotational operation of a rotational member (160-4) provided in a subwoofer (150-4) of an audio device (100-4) according to one or more embodiments of the present disclosure. FIG. 25 is a diagram illustrating a structure for adjusting a rotational angle of the rotational member (160-4) illustrated in FIG. 24.

[0160] Referring to FIGS. 23 and 24, the audio device (100-4) may include a sound bar (130-4) and a subwoofer (150-4) as a supporter. The sound bar (130-4) may be configured substantially the same as the sound bar (30) illustrated in FIGS. 2 and 3. The subwoofer (150-4) is largely the same as the subwoofer (150) illustrated in FIGS. 11 and 12, and may include a structure capable of adjusting the inclination angle of the sound bar. Hereinafter, the structure of the subwoofer (150-4) will be described.

[0161] The tilt angle adjustment structure of the sound bar may be provided on the upper part of the subwoofer (150-4) and may include a rotating member (160-4) and a locking structure (170-4) that can adjust the rotating member (160-4) to a predetermined angle.

[0162] A receiving groove (151-4) may be provided on the upper part of the subwoofer (150-4) in which a rotating member (160-4) can be rotatably received. An opening (153-4) connected to one side of the receiving groove (151-4) may be provided on the front of the subwoofer (150-4). The rotating member (160-4) may be adjusted to tilt the sound bar (130-4) at a predetermined angle toward the front or rear of the subwoofer (150-4).

[0163] The rotating member (160-4) may be provided with a joining groove (161-4) into which the first part (130a-4) or the second part (130b-4) of the sound bar (130-4) is detachably inserted. When the sensor (133-4) included in the audio device (100-4) is applied as a magnetic switch sensor, a magnet (133c-4) of the magnetic switch sensor may be placed on the rotating member (160-4). When the first end (130a-4) of the sound bar (130-4) of the sensor (133-4) is inserted into the coupling groove (161-4) of the rotating member (160-4), the first reed switch (133a-4) of the sensor (133-4) is turned on by the magnetic force of the magnet (133c-4), and a sensing value corresponding to the first vertical direction of the sound bar (130-4) can be obtained. In addition, when the second end (130b-4) of the sound bar (130-4) is inserted into the coupling groove (161-4) of the rotating member (160-4), the second reed switch (133b-4) of the sensor (133-4) is turned on by the magnetic force of the magnet (133c-4) and a sensing value corresponding to the first vertical direction of the sound bar (130-4) can be obtained.

[0164] The rotating member (160-4) may be provided with a through hole (163-4) on a side corresponding to the opening (153-4) of the subwoofer (150-4). The through hole (163-4) of the rotating member (160-4) does not interfere with the sound output to the second sound transducer (140FL-4) or the third sound transducer (140FR-4) of the sound bar (130-4). For example, it may be provided at a position corresponding to the opening (153-4) of the subwoofer (150-4). Accordingly, when the first end (130a-4) of the sound bar (130-4) is inserted into the joining groove (161-4) of the rotating member (160-4), the second sound transducer (140FL-4) of the sound bar (130-4) can correspond to the through hole (163-4) of the rotating member (160-4). The sound output from the second sound transducer (140FL-4) of the sound bar (130-4) can be radiated to the outside of the subwoofer (150-4) through the joining groove (161-4) of the rotating member (160-4) and the opening (153-4) of the subwoofer (150-4). In addition, when the second end (130b-4) of the sound bar (130-4) is inserted into the joining groove (161-4) of the rotating member (160-4), the second sound transducer (140FR-4) of the sound bar (130-4) can correspond to the through hole (163-4) of the rotating member (160-4). The sound output from the third sound transducer (140FR-4) of the sound bar (130-4) can be radiated to the outside of the subwoofer (150-4) through the joining groove (161-4) of the rotating member (160-4) and the opening (153-4) of the subwoofer (150-4).

[0165] The rotating member (160-4) may be configured to be rotatable by a hinge axis (165-4) within the receiving groove (151-4) of the subwoofer (150-4). The hinge axis (165-4) may be arranged approximately perpendicular to the vertical direction of the subwoofer (150-4). The rotating member (160-4) may rotate within a predetermined angular range (α) in a clockwise or counterclockwise direction around the hinge axis (165-4), as shown in FIG. 24.

[0166] Referring to FIG. 25, the subwoofer (150-4) may be provided with a locking structure (170-4) that allows the rotating member (160-4) to rotate around a hinge axis (165-4) and maintain the rotated angle. The locking structure (170-4) may maintain the rotating member (160-4) tilted at a predetermined angle toward the front or rear of the subwoofer (150-4).

[0167] For example, the locking structure (170-4) may include a stopper (171-4) flexibly positioned in a guide groove (173-4) provided inside the subwoofer (150-4) adjacent to the hinge axis (165-4), and a plurality of locking grooves (177-4) into which the ends of the stoppers (171-4) are detachably inserted.

[0168] The rear end of the stopper (171-4) can be elastically supported by an elastic member (e.g., a coil spring) (175-4) inserted into the guide groove (173-4). The stopper (171-4) can be pressed toward the hinge shaft (165-4) by the elastic force of the elastic member (175-4). A plurality of locking grooves (177-4) can be provided at regular intervals on the outer surface of the hinge shaft (165-4) along the circumferential direction of the hinge shaft (165-4).

[0169] The stopper (171-4) can flexibly move within the guide groove (173-4) while rotating the rotation member (160-4) clockwise or counterclockwise about the hinge axis (165-4). When the tip of the stopper (171-4) is inserted into one of the plurality of locking grooves (177-4), the rotation member (160-4) can be fixed in a vertical direction or fixed at a predetermined angle toward the front or rear of the subwoofer (150-4).

[0170] FIG. 26 is a drawing showing an example of placing an audio device (100-4) according to one or more embodiments of the present disclosure in a performance venue.

[0171] The audio device (100-4) can be used by appropriately adjusting the angle of the sound bar (130-4) according to the shape of the performance hall (height of the stage and seats, arrangement, etc.).

[0172] For example, when using an audio device (100-4) in a performance hall where the seats (180-4) are formed to gradually rise higher as they get farther from the stage (e.g., tiered seats), as shown in Fig. 26, the sound bar (130-4) can be adjusted to tilt at a predetermined angle (β) toward the rear of the subwoofer (150-4) via the rotating member (160-4) so ​​as to effectively transmit the sound output from the sound bar (130-4) to the rear of the seats (180-4).

[0173] Meanwhile, when using an audio device (100-4) in a performance hall where the stage is higher than the audience seats and the audience seats are flat and placed close to the stage, the sound bar (130-4) can be tilted at a predetermined angle in front of the subwoofer (150-4) to effectively transmit sound to the audience seats.

[0174] FIG. 27 is an assembly diagram showing an example of an audio device (100-5) including a sound bar (130-5) and a subwoofer (150-5) as a supporter according to one or more embodiments of the present disclosure.

[0175] Referring to FIG. 27, the audio device (100-5) may include a sound bar (130-5) and a subwoofer (150-5) as a supporter. The sound bar (130-5) may be configured substantially the same as the sound bar (30) illustrated in FIGS. 2 and 3. The subwoofer (150-5) is largely the same as the subwoofer (150) illustrated in FIGS. 11 and 12, and the joining groove on the upper portion of the subwoofer (150-5) may be omitted.

[0176] The sound bar (130-5) can be fixed to the upper surface (150a-5) of the subwoofer (150-5) in the first vertical direction or the second vertical direction via the bracket (160-5). The bracket (160-5) can include a base (161-6) fixed to the upper surface (150a-5) of the subwoofer (150-5) via a fastening member (e.g., a screw), and an extension portion (163-5) extending vertically from one end of the base (161-5) and fastened to the rear surface (131b-5) of the sound bar (130-5) via the fastening member.

[0177] The sound bar (130-5) can be fixed in the first vertical direction to the upper surface (150a-5) of the subwoofer (150-5) by the bracket (160-5). In this case, the left side (131b-5) of the sound bar (130-5) can be in contact with the upper surface of the subwoofer (150-5). The second sound transducer (140FL-5) of the sound bar (130-5) is not covered by any part of the subwoofer (150-5). Therefore, no separate opening is provided in the subwoofer (150-5). The sound output from the second sound transducer (140FL-5) of the sound bar (130-5) can be smoothly transmitted to the front of the subwoofer (150-5) without being interfered with by the subwoofer (150-5).

[0178] The sound bar (130-5) can be fixed in the second vertical direction to the upper surface (150a-5) of the subwoofer (150-5) by the bracket (160-5). In this case, the left side (131b-5) of the sound bar (130-5) can be in contact with the upper surface of the subwoofer (150-5). The sound output from the third acoustic transducer (140FR-5) of the sound bar (130-5) can be smoothly transmitted to the front of the subwoofer (150-5) without being interfered by the subwoofer (150-5).

[0179] One or more embodiments according to the present disclosure can improve usability by vertically arranging a sound bar even in a narrow installation space such as a performance hall.

[0180] FIG. 28 is a diagram illustrating an example of an audio system according to one or more embodiments of the present disclosure, wherein the audio system is composed of a plurality of audio devices (100a-6, 100b-6).

[0181] Referring to FIG. 28, the audio system may be composed of a first audio device (100a-6) and a second audio device (100b-6). Each of the first audio device (100a-6) and the second audio device (100b-6) may be configured substantially the same as the audio device (10) illustrated in FIG. 2. The first audio device (100a-6) may include a first sound bar (130a-6) and a supporter (150a-6) to which the first sound bar (130a-6) is coupled in a first vertical direction or a second vertical direction. The second audio device (100b-6) may include a second sound bar (130b-6) and a supporter (150b-6) to which the second sound bar (130b-6) is coupled in a first vertical direction or a second vertical direction.

[0182] The first audio device (100a-6) and the second audio device (100b-6) may be spaced apart from each other on the upper surface of the table (210-6). In this case, a display device (200-6) may be placed between the first audio device (100a-6) and the second audio device (100b-6). A subwoofer (230-6) may be placed on one side of the table (210-6).

[0183] An audio system according to an embodiment may implement stereo sound. For example, a processor (93, see FIG. 8) of a first audio device (100a-6) may receive a sound source from a display device (200-6). When a sensor (33, see FIG. 8) of the first audio device (100a-6) identifies that the first sound bar (130a-6) is in a first vertical direction, the processor (93) of the first audio device (100a-6) may execute instructions stored in a memory (91, see FIG. 8) based on the first vertical direction. For example, the processor (93) of the first audio device (100a-6) can execute an instruction to transmit front left channel signals to each of the plurality of acoustic transducers (40C, 40FL, 40FR, 40SL, 40SR, 40TL, 40TR, see FIG. 3) of the first sound bar (130a-6) through the audio signal processing module (81, see FIG. 8) of the first audio device (100a-6).

[0184] The second audio device (100b-6) can be controlled by the first audio device (100a-6). For example, the first audio device (100a-6) can receive a sound source through the wireless communication module (32, see FIG. 1) of the first audio device (100a-6). When the sensor (33) of the second audio device (100b-6) identifies that the second sound bar (130b-6) is in the second vertical direction, the processor (93) of the second audio device (100b-6) can execute instructions stored in the memory (91) based on the second vertical direction. For example, the processor (93) of the second audio device (100b-6) can execute an instruction to transmit front right channel signals to each of the plurality of acoustic transducers (40C, 40FL, 40FR, 40SL, 40SR, 40TL, 40TR) of the second sound bar (130b-6) via the audio signal processing module (81) of the second audio device (100b-6). In this way, the audio system can implement stereo sound.

[0185] An audio system according to one embodiment can implement surround sound by causing a processor (93) of a first audio device (100a-6) and a processor (93) of a second audio device (100b-6) to execute instructions different from the instructions described above.

[0186] For example, the processor (93) of the first audio device (100a-6) can execute an instruction to transmit front center channel signals to the first, second, third, fourth, and fifth sound transducers (40C, 40FL, 40FR, 40SL, 40SR) of the first sound bar (130a-6) and to transmit side left channel signals to the sixth and seventh sound transducers (40TL, 40TR) through the audio signal processing module (81) of the first audio device (100a-6). The processor (93) of the second audio device (100b-6) can execute an instruction to transmit front center channel signals to the first, second, third, fourth, and fifth sound transducers (40C, 40FL, 40FR, 40SL, 40SR) of the second sound bar (130b-6) and to transmit side right channel signals to the sixth and seventh sound transducers (40TL, 40TR) through the audio signal processing module (81) of the second audio device (100b-6).

[0187] An audio system according to one embodiment can implement Dolby Atmos sound by causing the processor (93) of the first audio device (100a-6) and the processor (93) of the second audio device (100b-6) to execute instructions different from the instructions described above.

[0188] The processor (93) of the first audio device (100a-6) and the processor (93) of the second audio device (100b-6) may execute instructions different from the instructions described above. For example, the processor (93) of the first audio device (100a-6) may execute instructions to transmit front center channel signals to the first, second, third, and fourth sound transducers (40C, 40FL, 40FR, 40SL) of the first sound bar (130a-6), to transmit side left channel signals to the sixth and seventh sound transducers (40TL, 40TR), and to transmit top left channel signals to the fifth sound transducer (40SR) via the audio signal processing module (81) of the first audio device (100a-6). The processor (93) of the second audio device (100b-6) can execute instructions to transmit front center channel signals to the first, second, third, and fourth sound transducers (40C, 40FL, 40FR, 40SL) of the second sound bar (130b-6), side right channel signals to the sixth and seventh sound transducers (40TL, 40TR), and top right channel signals to the fifth sound transducer (40SR) through the audio signal processing module (81) of the second audio device (100b-6).

[0189] An audio system according to one embodiment can output diverse sounds by causing a processor (93) of a first audio device (100a-6) and a processor (93) of a second audio device (100b-6) to execute instructions for transmitting channel signals of various patterns to a first sound bar (130a-6) and a second sound bar (130b-6).

[0190] FIG. 29 is a diagram illustrating an example of an audio system according to one or more embodiments of the present disclosure, wherein the audio system is composed of a plurality of audio devices (100a-7, 100b-7).

[0191] Referring to FIG. 29, the audio system may be composed of a first audio device (100a-7) and a second audio device (100b-7). Each of the first audio device (100a-7) and the second audio device (100b-7) may be configured substantially identically to the audio device (100) illustrated in FIG. 12.

[0192] The processor (93) of the first audio device (100a-7) and the processor (93) of the second audio device (100b-7) can execute instructions for transmitting channel signals of various patterns to the first sound bar (130a-7) and the second sound bar (130b-7).

[0193] FIG. 30 is a diagram illustrating an example of an audio system according to one or more embodiments of the present disclosure, wherein the audio system comprises a plurality of audio devices (100a-8, 100b-8).

[0194] Referring to FIG. 30, the audio system may be configured with a first audio device (100a-8) and a second audio device (100b-8). The first audio device (100a-7) may be configured substantially identically to the audio device (10) illustrated in FIG. 2, and the second audio device (100b-7) may be configured substantially identically to the audio device (100) illustrated in FIG. 12.

[0195] One or more embodiments according to the present disclosure can implement a three-dimensional sound by appropriately arranging multiple audio devices in the front, back, left, and right directions depending on the location where the audio devices are used (e.g., home, small theater, indoor performance hall, outdoor performance hall, etc.).

[0196] Various embodiments of the present disclosure may be implemented as software including one or more instructions stored in a storage medium (e.g., memory (93)) readable by a machine (e.g., audio device (10)). For example, a processor (e.g., processor (93)) of the machine (e.g., audio device (10)) may call at least one command among the one or more commands stored from the storage medium and execute it. This enables the machine to operate to perform at least one function according to the at least one command called. The one or more commands may include code generated by a compiler or code executable by an interpreter.
