[0043] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application.

[0044] This application provides a sofa in an embodiment; please refer to [link / reference]. Figures 1 to 11 The sofa includes a main seat 1, a back support device 2, and a playback device 3. The back support device 2 is disposed on one side of the main seat 1 along a first direction R1, which is intersected with the vertical direction R3. The playback device 3 is disposed on at least one side of the back support device 2 along a second direction R2, which is intersected with both the first direction R1 and the vertical direction R3. The playback device 3 includes a player 31 for at least playing audio. The player 31 is capable of translating and / or rotating relative to the back support device 2 to change the position of the player 31 relative to the back support device 2.

[0045] For example, the player 31 is rotatable relative to the back support 2.

[0046] For example, the player 31 is capable of translation relative to the back support device 2.

[0047] For example, the player 31 is capable of translation and rotation relative to the back support 2.

[0048] In this embodiment, at least one side of the back support device 2 along the second direction R2 is provided with a playback device 3. When the user sits on the sofa, the player 31 is close to the user's ears. The player 31 can translate and / or rotate relative to the back support device 2 to change the position of the player 31 relative to the back support device 2. The position of the player 31 can be changed according to the user's position. When the user sits on the sofa in different postures, the position of the player 31 relative to the user's ears can be adjusted more accurately, so that the user can get a better acoustic experience.

[0049] For other embodiments in this application, please refer to Figures 1-10 The playback device 3 also includes a transmission device 32, which is respectively disposed on the player 31 and the back support device 2.

[0050] In this embodiment, the transmission device 32 is respectively disposed on the player 31 and the back support device 2. The appropriate transmission device 32 can be arranged according to the movement requirements of the player 31, which is beneficial to flexibly match the movement requirements of the player 31.

[0051] It is understood that the playback device 3 is not limited to including the transmission device 32. Exemplarily, the playback device 3 is provided with the transmission device 32, and the playback device 3 has a rotatable cam shaft that is inserted into the back support device 2 so that the player 31 can rotate relative to the back support device 2.

[0052] For other embodiments in this application, please refer to Figure 3 and Figure 4The transmission device 32 includes a support component 321 and a transmission component 322. The support component 321 is connected to the player 31. The transmission component 322 is disposed on the back support device 2. The transmission component 322 can rotate relative to the support component 321. The central axis of rotation of the support component 321 relative to the transmission component 322 is a preset central axis 33. The preset central axis 33 is arranged to intersect the second direction R2 and the thickness direction of the back support device 2.

[0053] In this embodiment, the central axis of rotation of the bearing component 321 relative to the transmission component 322 is a preset central axis 33. The preset central axis 33 is arranged to intersect the second direction R2 and the thickness direction of the back support device 2. The bearing component 321 and the transmission component 322 rotate relative to each other, so that the player 31 can rotate relative to the back support device 2, thereby adjusting the relative position of the player 31 on the back support device 2 and adjusting the orientation of the player 31. When the user sits on the sofa in different postures, the user's ears can obtain a more consistent auditory effect, so that the user can obtain a better acoustic experience.

[0054] It is understood that the carrier component 321 is not limited to rotating relative to the transmission component 322. Exemplarily, the player 31 is capable of sliding on the carrier component 321.

[0055] For example, the back support device 2 and the main seat 1 cannot rotate relative to each other, and the back support device 2 and the main seat 1 can be arranged in the vertical direction R3.

[0056] For example, the back support device 2 and the main seat 1 cannot rotate relative to each other, and the back support device 2 and the main seat 1 can be arranged along the first direction R1.

[0057] For example, the back support device 2 is rotatable relative to the main seat 1, and the back support device 2 is rotatable to be arranged with the main seat 1 in the vertical direction R3 or in the first direction R1.

[0058] For other embodiments in this application, please refer to Figure 3 and Figure 4 One of the bearing assembly 321 and the transmission assembly 322 has a rotating shaft 323. The bearing assembly 321 rotates about the central axis of the rotating shaft 323 relative to the transmission assembly 322. The bearing assembly 321 can be switched to a locked state relative to the transmission assembly 322 to restrict the rotation of the bearing assembly 321.

[0059] For example, the support component 321 and the rotating shaft 323 may rotate relative to each other, or there may be no relative rotation between the support component 321 and the rotating shaft 323.

[0060] For example, there may be relative rotation between the transmission component 322 and the rotating shaft 323, or there may be no relative rotation between the transmission component 322 and the rotating shaft 323.

[0061] For example, when an external force is applied to the support component 321, the support component 321 can rotate relative to the transmission component 322 about the central axis of the rotating shaft 323.

[0062] For example, when the external force applied to the bearing component 321 is removed, the bearing component 321 switches to a locked state relative to the transmission component 322, and the bearing component 321 cannot rotate relative to the transmission component 322.

[0063] For example, a damping element is provided between the load-bearing component 321 and the transmission component 322, and the damping force of the damping element can switch the load-bearing component 321 to a locked state relative to the transmission component 322.

[0064] For example, the support component 321 and the transmission component 322 have coaxially arranged pin holes. Inserting a pin into the pin hole of the support component 321 and the pin hole of the transmission component 322 switches the support component 321 to a locked state relative to the transmission component 322.

[0065] For example, the load-bearing component 321 and the transmission component 322 are interference-fitted, and the static friction between the load-bearing component 321 and the transmission component 322 can switch the load-bearing component 321 to a locked state relative to the transmission component 322.

[0066] In this embodiment, an external force is applied to the support component 321, causing it to rotate relative to the transmission component 322 about the central axis of the rotating shaft 323. This rotation drives the player 31 to rotate relative to the back support device 2, adjusting the position of the player 31. Once the player 31 is in position, the external force is removed, and the support component 321 can switch to a locked state relative to the transmission component 322, restricting the relative rotation between the support component 321 and the transmission component 322, thereby allowing the player 31 to remain in a suitable position.

[0067] In other embodiments of this application, one of the bearing component 321 and the transmission component 322 has a rotating shaft 323, and the other of the bearing component 321 and the transmission component 322 has a bushing 324 sleeved on the rotating shaft 323. The transmission device 32 also includes a damping element 325, which abuts between the rotating shaft 323 and the bushing 324.

[0068] For example, the damping element 325 is made of rubber or silicone.

[0069] In this embodiment, one of the bearing component 321 and the transmission component 322 has a rotating shaft 323, and the other of the bearing component 321 and the transmission component 322 has a bushing 324 sleeved on the rotating shaft 323. The transmission device 32 also includes a damping element 325, which abuts between the rotating shaft 323 and the bushing 324. The damping element 325 can increase the rotational resistance of the rotating shaft 323 and the bushing 324. When the player 31 is adjusted to the position, the rotational resistance of the bearing component 321 and the transmission component 322 is large. When the external force is removed, the bearing component 321 switches to a locked state relative to the transmission component 322. The bearing component 321 and the transmission component 322 cannot rotate relative to each other, so that the player 31 can be kept in a suitable position.

[0070] It is understandable that the transmission device 32 is not limited to the installation of damping element 325.

[0071] For other embodiments in this application, please refer to Figures 3 to 10 The transmission assembly 322 includes a guide 3221 and a transmission device 3222. The guide 3221 is disposed on the back support device 2. The transmission device 3222 is mounted on the guide 3221. The guide 3221 guides the transmission device 3222 to move along the second direction R2. The load-bearing assembly 321 is rotatably connected to the transmission device 3222.

[0072] In this embodiment, the guide 3221 is disposed on the back support device 2, and the transmission device 3222 is mounted on the guide 3221. The guide 3221 guides the transmission device 3222 to move along the second direction R2. The bearing assembly 321 is rotatably connected to the transmission device 3222. Through the guide 3221 and the transmission device 3222, the player 31 can translate along the second direction R2. The player 31 can rotate and translate relative to the back support device 2, enabling the player 31 to move in multiple directions, increasing the movable range of the player 31, and facilitating precise adjustment of the position of the player 31.

[0073] It is understood that the transmission assembly 322 may not include the guide 3221 and the transmission device 3222. Exemplarily, the transmission assembly 322 includes a telescopic rod, one end of which is disposed on the back support device 2, and the other end of which is disposed on the load-bearing assembly 321. The telescopic rod is capable of extending and retracting along the second direction R2.

[0074] For other embodiments in this application, please refer to Figure 3 and Figure 4 The guide 3221 is rotatably connected to the back support device 2. The guide 3221 has a transmission thread 3223 extending along the second direction R2. The transmission device 3222 and the transmission thread 3223 are configured as a threaded transmission pair.

[0075] It should be noted that the guide 3221 is rotatably connected to the back support device 2, and the transmission device 3222 and the transmission thread 3223 form a threaded transmission pair. The guide 3221 rotates relative to the back support device 2, driving the transmission device 3222 to move along the guide 3221. The transmission device 3222 does not rotate relative to the back support device 2; instead, it translates relative to the back support device 2. When it is not necessary to move the transmission device 3222, it can remain relatively stationary with respect to the guide 3221.

[0076] For example, the rotation center line of the support component 321 relative to the transmission 3222 intersects the rotation center line of the guide 3221 relative to the back support device 2.

[0077] For example, the transmission thread 3223 on the guide 3221 is an external thread, and the transmission device 3222 has an internal thread, with the internal and external threads engaging in transmission.

[0078] For example, each playback device 3 has two guides 3221.

[0079] In this embodiment, the guide 3221 is rotatably connected to the back support device 2. The guide 3221 has a transmission thread 3223 extending along the second direction R2. The transmission device 3222 and the transmission thread 3223 are configured as a threaded transmission pair. The rotation of the guide 3221 drives the transmission device 3222 to translate along the second direction R2. The static friction between the transmission device 3222 and the guide 3221 is large. When the transmission device 3222 does not need to move, the transmission device 3222 can remain stationary relative to the guide 3221, which better controls the position of the transmission device 3222, so that the player 31 can be kept in a suitable position.

[0080] In other embodiments of this application, the guide 3221 is a guide rail extending along the second direction R2.

[0081] For example, the guide 3221 is a guide rail, and the actuator 3222 includes a sliding sleeve.

[0082] For example, the back support device 2 includes a connector 23, and the guide 3221 is rotatably connected to the connector 23.

[0083] For example, the support assembly 321 includes a support body 3212 and a first flip member 3213 connected to each other, the player 31 is connected to the support body 3212, and the transmission device 3222 includes a transmission member 3224 and a second flip member 3225 connected to each other, and the transmission member 3224 and the transmission thread 3223 are configured as a threaded transmission pair.

[0084] For example, the first flipper 3213 and the second flipper 3225 constitute at least a portion of the hinge structure.

[0085] For example, the first flipper 3213 and the second flipper 3225 constitute at least a portion of the hinge structure.

[0086] For other embodiments in this application, please refer to Figures 3 to 10 The support component 321 has a support surface 3211, the player 31 is located on the side of the support component 321 facing the support surface 3211, and the back support device 2 is provided with playback devices 3 on both sides along the second direction R2. The player 31 includes a housing 311 and a playback body 312 for at least playing audio, and the playback body 312 is located inside the housing 311.

[0087] When the player 31 is located away from the back support device 2 on the support component 321 and the support surface 3211 is parallel to the second direction R2, the distance between the two outer shells 311 is the first distance L1, which is 200mm to 1200mm or 1000mm to 3000mm.

[0088] When the two players 31 are located between the two support components 321 along the second direction R2 and the support surface 3211 is perpendicular to the second direction R2, the distance between the two outer shells 311 is the second distance L2, which is 200mm to 1500mm or 1000mm to 3000mm.

[0089] It should be noted that the distance between the two outer shells 311 is the minimum distance between the two outer shells 311 along the second direction R2.

[0090] For example, when the player 31 is located away from the back support device 2 on the support component 321 and the support surface 3211 is parallel to the second direction R2, the actuator 3222 moves along the guide 3221 to change the first distance L1 of the two side housings 311.

[0091] For example, when the two players 31 are located between the two support components 321 along the second direction R2 and the support surface 3211 is perpendicular to the second direction R2, the actuator 3222 moves along the guide 3221 to change the second distance L2 of the two housings 311.

[0092] For example, a first distance L1 of 200mm to 1200mm is suitable for a single sofa.

[0093] For example, a second distance L2 of 200mm to 1500mm is suitable for a single sofa.

[0094] For example, a first distance L1 of 1000mm to 3000mm is suitable for multi-person sofas.

[0095] For example, a second distance L2 of 1000mm to 3000mm is suitable for multi-person sofas.

[0096] For example, the first distance L1 is 200mm, 400mm, 600mm, 800mm, 1000mm or 1200mm.

[0097] For example, the first distance L1 is 1000mm, 1500mm, 2000mm, 2400mm, 2800mm or 3000mm.

[0098] For example, the second distance L2 is 200mm, 500mm, 700mm, 800mm, 1000mm, 1200mm or 1500mm.

[0099] For example, the second distance L2 is 1000mm, 1500mm, 2000mm, 2400mm, 2800mm or 3000mm.

[0100] For example, the second direction R2 is parallel to the left and right directions.

[0101] In this embodiment, playback devices 3 are provided on both sides of the back support device 2 along the second direction R2. When the user sits on the sofa, the audio played by the players 31 located on both sides of the user can surround the user, providing a better acoustic experience. The first distance L1 between the two players 31 is 200mm to 1200mm or 1000mm to 3000mm, which is within a suitable range. The second distance L2 between the two players 31 is 200mm to 1500mm or 1000mm to 3000mm, which is also within a suitable range. Without restricting the user's position, the distance between the players 31 and the user's ears can be adjusted within a suitable range, allowing the user to obtain a better acoustic experience. The adjustable distance between the two players 31 along the second direction R2 allows for precise adjustment of the position between the players 31 and the user's ears, ensuring a better acoustic experience for users with different head shapes.

[0102] It is understood that the first distance L1 is not limited to 200mm to 1200mm or 1000mm to 3000mm. For example, the first distance L1 is 180mm or the first distance L1 is greater than 3000mm.

[0103] It is understood that the second distance L2 is not limited to 200mm to 1500mm or 1000mm to 3000mm. For example, the second distance L2 is 180mm or the first distance L1 is greater than 3000mm.

[0104] In other embodiments of this application, the angle between the bearing surface 3211 and the second direction R2 is a first angle, which is 45° to 225°.

[0105] For example, the first included angle is 80° to 180°.

[0106] For example, the first included angle is 45°, 60°, 90°, 120°, 150°, 180°, or 225°.

[0107] For example, the first included angle of the playback devices 3 on both sides can be the same or different.

[0108] The first included angle is shown as angle a in the figure.

[0109] For example, the player 31 also includes a mounting post connected to the outside of the housing 311. When the player 31 is located away from the back support device 2 on the support assembly 321 and the support surface 3211 is parallel to the second direction R2, the mounting post is located on the side of the housing 311 facing the other housing 311 along the second direction R2.

[0110] For example, the player 31 also includes a decorative cover, which is installed on the outside of the housing 311. When the two players 31 are located between the two support components 321 along the second direction R2 and the support surface 3211 is perpendicular to the second direction R2, the decorative cover is located on the side of the housing 311 away from the guide 3221 along the thickness direction of the back support device 2.
