[0046] It should be noted that the innovation of the utility model does not involve the specific structure of the gear adjusting mechanism 353, the gear adjusting mechanism 353 can adopt any known structure, and can meet the different gear adjusting functions of the rotation angle, so as to adapt to the requirements of different passengers on the rotation angle when experiencing immersive music. As a specific example, the gear adjusting mechanism 353 can be a ratchet type gear adjusting mechanism 353, which comprises a ratchet wheel, a pawl, a pawl support, a limiting pin, a support return torsion spring, a second return torsion spring, the rotating shaft 352 is fixedly connected with the first rotating arm 351 and pivotally connected with the second rotating arm 351, wherein the first rotating arm 351 is fixedly connected with the intermediate piece 31, and the second rotating arm 351 is fixedly connected with the side connecting piece 32, the pawl support is arranged on the rotating shaft 352 or the first rotating arm 351, the ratchet wheel is arranged on the second rotating arm 351, the pawl matched with the ratchet wheel is rotatably arranged on the pawl support, the limiting pin is arranged on the side surface of the pawl, the limiting pin is matched with the limiting hole of the second rotating arm 351, the pawl is limited, the first return torsion spring is arranged between the second rotating arm 351 and the pawl support, and the second return torsion spring is arranged between the pawl and the pawl support; when the ratchet wheel and the pawl are located at the initial position, the side connecting piece 32 and the intermediate piece 31 are in the relative unfolding state, the ratchet wheel and the pawl are engaged, when the external force drives the side connecting piece 32 and the second rotating arm 351 to rotate around the rotating shaft 352, the ratchet wheel and the pawl are matched, the gear adjustment is realized, when the external force continuously drives the side connecting piece 32 and the second rotating arm 351 to rotate to the position where the limiting pin is limited by the limiting hole, the pawl cannot continue to rotate, the second rotating arm 351 drives the pawl to reversely rotate by overcoming the force of the second return torsion spring through the limiting pin, the pawl is disengaged from the ratchet wheel, and unlocking is realized, when the external force is removed, the second rotating arm 351 returns to the initial position under the drive of the first return torsion spring, the pawl also returns to the initial position under the drive of the second return torsion spring, and the pawl is engaged with the ratchet wheel again.

[0047] The use scene requirement of the sofa is higher than that of the chair, therefore in the sofa of the utility model, the headrest 3 has two states, one is an initial unfolding state, and the other is a rotating folding state; in the initial unfolding state, the side connecting piece 32 and the intermediate piece 31 are relatively unfolded, so that the headrest 3 as a whole is in a flat state, and the sound equipment 4 is away from the ear of the passenger, when the passenger rests on the sofa, the passenger can normally adjust the body posture, such as twisting the head to talk or leaning the head to rest, and the side connecting piece 32 of the headrest 3 does not affect the passenger, and the normal use of the sofa is met; in the rotating folding state, the side connecting piece 32 with the sound equipment 4 rotates inward relative to the intermediate piece 31, when the passenger rests on the sofa, the head of the passenger can lean on the intermediate piece 31 of the headrest 3, so that the body is relaxed, and the sound equipment 4 is close to the ear of the passenger, at this time, the music playing can provide immersive music experience, the sound feeling is better, and the privacy is higher.

[0048] In the above scheme, the combination of the sound 4 installed on the headrest 3, the first vibrator 5 installed on the backrest 2 and the second vibrator 6 installed on the sofa seat 1 can increase the feeling of vibration on the body on the basis of the immersive music experience, and can bring the experience of 4D music; specifically, when the sound 4 plays music, the first vibrator 5 and the second vibrator 6 generate corresponding vibrations according to the sound effect signal, so that the sofa vibrates synchronously with the sound effect, thereby enhancing the immersive feeling and real feeling of the sound effect, wherein the first vibrator 5 provides vibration feeling for the back of the occupant, and the second vibrator 6 provides vibration feeling for the hips of the occupant. It can be understood that only the first vibrator 5 or only the second vibrator 6 can be provided.

[0049] Referring to Figure 4 Based on the presence of the gear adjusting mechanism 353, the local size of the hinge 35 will be larger, in order to control the overall thickness size of the headrest 3 and the gap size between the intermediate piece 31 and the side connecting piece 32, preferably, the intermediate piece 31 and the side connecting piece 32 are provided with a connected avoiding groove 36 and a connecting groove 37, the avoiding groove 36 corresponds to the gear adjusting mechanism 353, the other end of the rotating arm 351 is inserted into the connecting groove 37 and fixedly connected, specifically, the width of the avoiding groove 36 is greater than the width of the connecting groove 37, the other end of the rotating arm 351 is formed with a bending part 3511, and the bending part 3511 is fixedly connected with the intermediate piece 31 or the side connecting piece 32 by screws. Among them, by setting the avoiding groove 36, the space at the avoiding groove 36 is used to accommodate the gear adjusting mechanism 353, so that the gap between the intermediate piece 31 and the side connecting piece 32 can be smaller, without using the scheme of increasing the gap between the intermediate piece 31 and the side connecting piece 32 to avoid the gear adjusting mechanism 353 or using the scheme of moving the gear adjusting mechanism 353 backward to form avoidance, therefore, the overall thickness size of the headrest 3 can be controlled to be smaller and the gap between the intermediate piece 31 and the side connecting piece 32 can be controlled to be smaller, so that in the initial unfolded state, the position between the intermediate piece 31 and the side connecting piece 32 will not cause a collapse feeling, and better supporting effect can be provided.

[0050] Referring to Figure 1In the embodiment, the control panel 500 is arranged on the armrest 200, and can be arranged on the upper surface or inner side surface of the armrest 200, and then arranged in the mounting groove. In some sofas for multiple people or corner sofas, the control panel 500 can also be arranged on the tea table 300. The control panel 500 is provided with a first function key 501 and a second function key 502. The first function key 501 and the second function key 502 are preferably combined with the rotary type and the pressing type. When the first function key 501 is rotated, the volume of the sound equipment 4 is adjusted. When the first function key 501 is pressed, the sound equipment 4 is turned on or off, or played or paused. When the second function key 502 is rotated, the vibration of the first vibrator 5 and the second vibrator 6 is adjusted. When the second function key 502 is pressed, the input mode is switched or the control of the two vibrators is switched, that is, the two vibrators are simultaneously controlled or one of the two vibrators is controlled. The control panel 500 can also be provided with other function keys or interfaces, which are not described here.

[0051] Referring to Figure 7 In the embodiment, the sound equipment 4 is preferably indirectly arranged on the side connecting piece 32, so as to optimize the leaning feeling of the headrest 3 on the sound equipment 4. The headrest 3 further comprises a soft pillow 33 and a pillow cover 34. The soft pillow 33 is filled with flexible fillers such as down or cotton. The soft pillow 33 can also be made of sponge. When the soft pillow 33 is made of sponge, the outside of the sponge can be wrapped with a layer of fabric or can not be wrapped with a layer of fabric. The sound equipment 4 is arranged on the soft pillow 33, and the soft pillow 33 is wrapped in the middle piece 31 and the side connecting piece 32 by the pillow cover 34, so that the sound equipment 4 is indirectly arranged on the side connecting piece 32. The soft pillow 33 is preferably designed in a segmented independent small soft pillow, so as to facilitate the rotation of the side connecting piece 32 and avoid the soft pillow 33 from bulging at the bending part. Specifically, the soft pillow 33 comprises a first soft pillow 331 and two second soft pillows 332. The first soft pillow 331 and the second soft pillows 332 are relatively independent. The first soft pillow 331 corresponds to the middle piece 31, and the second soft pillows 332 correspond to the side connecting piece 32. The second soft pillows 332 are provided with accommodating grooves 333. The sound equipment 4 is embedded in the accommodating grooves 333, and a space is reserved between the sound equipment 4 and the side connecting piece 32. Of course, in order to facilitate the sound transmission, when the pillow cover 34 is made of leather or a material with poor sound transmission, a plurality of sound transmission holes can be formed on the pillow cover 34 at positions corresponding to the sound equipment 4. When the pillow cover 34 is made of cloth or a material with good sound transmission, the sound transmission holes can not be formed on the pillow cover 34.

[0052] In other preferable embodiments, the pillow 33 can also be designed in one piece, and the pillow 33 has a receiving groove 333 at a position corresponding to the side connecting member 32, and the speaker 4 is embedded in the receiving groove 333, and a space is reserved between the speaker 4 and the side connecting member 32. In order to avoid the pillow 33 from bulging at the bending position, a local compression can be performed by adding a sewing line at the bending position.

[0053] In other preferable embodiments, the speaker 4 can also be fixedly connected to the side connecting member 32. Specifically, a mounting seat can be arranged on the side connecting member 32, and the speaker 4 is fixedly connected to the mounting seat, or a through groove is arranged on the side connecting member 32, and the speaker 4 is fixedly connected to the through groove.

[0054] Compared with the two schemes of embedding the speaker 4 in the pillow 33 and directly fixing the speaker 4 to the side connecting member 32, the former is more preferable, because in the initial unfolded state, when the head of the passenger is placed on the position corresponding to the speaker 4 in the headrest 3, the pillow 33 at the position will be compressed, and the compression stroke is relatively large. In the rotating and folding state, when the side connecting member 32 with the speaker 4 rotates to close to the ear of the passenger, according to the fitting condition, the pillow 33 at the position of the speaker 4 can not be compressed or can be compressed slightly. In order to control the immersive playing effect of the speaker 4, the distance between the speaker 4 and the front surface of the pillow 33 needs to be set to be small. When the scheme of directly fixing the speaker 4 to the side connecting member 32 is adopted, the allowable compression stroke of the pillow 33 at the position of the speaker 4 is small, which leads to a hard feeling of the pillow 33 at the position of the speaker 4 in the initial unfolded state, and the feeling of foreign matter is caused. When the scheme of embedding the speaker 4 in the pillow 33 is adopted, the distance between the speaker 4 and the front surface of the pillow 33 can be controlled to be small, and when the head contacts the speaker 4, the pillow 33 can be further compressed, so as to provide a buffer stroke, and the feeling of the pillow 33 at the position of the speaker 4 is soft.

[0055] Referring to Figure 7The first mounting structure of the sound box 4 is disclosed in the example. Based on the aforementioned scheme of embedding the sound box 4 in the pillow soft bag 33, in order to facilitate the installation and positioning of the sound box 4 in the pillow soft bag 33, it is further preferred that the accommodating groove 333 is in a penetrating form, the thickness of the pillow soft bag 33 is greater than the thickness of the sound box 4, based on the segmented pillow soft bag 33 and the accommodating groove 333 is specifically arranged on the second soft bag 332, so the thickness of the second soft bag 332 is greater than the thickness of the sound box 4, the front end of the sound box 4 is provided with a first limiting piece 41, the first limiting piece 41 is preferably a ring-shaped flange, so that the touch is smooth, the rear end of the sound box 4 is provided with a second limiting piece 42, the second limiting piece 42 is preferably a block structure locally protruding in the circumferential direction of the sound box 4 and is provided with a plurality of second limiting pieces 42, the plurality of second limiting pieces 42 are arranged in the circumferential direction of the sound box 4, so as to save materials and cost, the first limiting piece 41 and the second limiting piece 42 respectively abut the edges of the two openings of the accommodating groove 333. When installing, the sound box 4 is embedded in the accommodating groove 333, and the two ends of the sound box 4 respectively abut the edges of the two ends of the accommodating groove 333, the sound box 4 can locally compress the pillow soft bag 33 at the accommodating groove 333, the elasticity of the pillow soft bag 33 can be used to position the sound box 4, so that the sound box 4 is not easy to deviate, and the compression is a bilateral compression, so that the front end of the sound box 4 is kept a certain distance from the front surface of the pillowcase 34, and the rear end of the sound box 4 is kept a certain distance from the surface of the side connecting piece 32, so that the feeling of the sound box 4 is better, in the rotating folding state, the sound box 4 is not easy to be touched, so that the touch feeling of the sound box 4 is better, in the initial unfolding state, after the head of the occupant compresses the partial stroke and contacts the sound box 4, the distance between the sound box 4 and the side connecting piece 32 still allows the pillow soft bag 33 to be further compressed, thereby providing a double-layer buffering effect; on the other hand, the penetrating accommodating groove 333 also facilitates the wiring of the sound box 4, correspondingly, the side connecting piece 32 is provided with a wiring hole 321, so that the electric wire of the sound box 4 can enter the inside of the backrest 2 for the next step of wiring after passing through the wiring hole 321, and the hiding is realized.

[0056] Referring to Figure 8In the example, the thickness of the pillow 33 is greater than the thickness of the sound box 4, and a portion of the second soft pack 332 is laid in the space between the sound box 4 and the side connecting piece 32. At this time, the accommodating groove 333 can be a through type, and the end of the accommodating groove 333 close to the side connecting piece 32 is contracted so that the second soft pack 332 can be laid in the space between the sound box 4 and the side connecting piece 32. Alternatively, the accommodating groove 333 can only be opened in the direction away from the side connecting piece 32, and a hole for the wire of the sound box 4 is reserved. In the example, the positioning of the sound box 4 in the accommodating groove 333 is achieved by the elastic contraction of the second soft pack 332 to clamp the sound box 4 in the accommodating groove 333. In the example, the front end of the sound box 4 is provided with a first limiting piece 41, and the first limiting piece 41 abuts against the edge of the front opening of the accommodating groove 333.

Figure 10

[0064] In the sofa shown in the figure, the two control centers 700 are connected through Y-shaped connecting lines 600 included in the sofa, specifically, the Y-shaped connecting lines 600 comprise three interfaces, and the interface schematic diagram can be referred to in Figure 9 Figure 10 The two control centers 700 are connected through Y-shaped connecting lines 600 included in the sofa, specifically, the Y-shaped connecting lines 600 comprise three interfaces, and the interface schematic diagram can be referred to in Figure 11 Figure 11 The Y-shaped connecting line of the utility model is an interface structure schematic diagram. The Y-shaped connecting line 600 comprises a first interface P1, a second interface P2 and a third interface P3, and the connection between the first interface P1 and the second interface P2 and the connection between the first interface P1 and the third interface P3 can be referred to in Figures 11-12 The Y-shaped connecting line of the utility model is an interface structure schematic diagram. The Y-shaped connecting line 600 comprises a first interface P1, a second interface P2 and a third interface P3, and the connection between the first interface P1 and the second interface P2 and the connection between the first interface P1 and the third interface P3 can be referred to in Figures 11-12 ​​​As shown, the connection lines in the first interface P1 are P11-P15 respectively, the connection lines in the second interface P2 are P21-P25 respectively, the connection lines in the third interface P3 are P31-P35 respectively, for the first interface P1 and the second interface P2, the connection lines P11-P15 and the connection lines P21-P25 correspond to connection respectively, for the first interface P1 and the third interface P3, the connection lines P11-P12, P15 and the connection lines P31-P32, P35 correspond to connection, and the connection lines P13-P14 and the connection lines P33-P34 cross connection, that is, the connection line P13 and the connection line P34 cross connection, the connection line P14 and the connection line P33 cross connection, so that the signal transmission between the first interface P1 and the second interface P2 and the signal transmission between the first interface P1 and the third interface P3 form a difference, which can realize flexible selection and adjustment between the single-panel control mode and the double-panel control mode through the aforementioned signal transmission difference, that is, realize flexible selection and adjustment of the control panel 500 used to actually control the music seat body 100. More specifically, the first interface P1 is used to be electrically connected with one of the two control centers 700, the second interface P2 and the third interface P3 are used to be electrically connected with the other control center 700 of the two control centers 700 alternatively, in order to facilitate understanding, the control center 700 electrically connected with the first interface P1 is defined as the first control center, and the control center 700 electrically connected with the second interface P2 or the third interface P3 is defined as the second control center, and the first control center is specifically one of the control centers 700 connected with the control panel 500. Among them, the second interface P2 and the third interface P3 are electrically connected with the second control center alternatively, which can realize different panel control modes between the music seat body 100 controlled by the first control center and the music seat body 100 controlled by the second control center.

[0065] Further, the different panel control modes can include a single-panel control mode and a double-panel control mode, in actual application, the second interface P2 can be defined to realize the single-panel control mode and the third interface P3 can be defined to realize the double-panel control mode, or the second interface P2 can be defined to realize the double-panel control mode and the third interface P3 can be defined to realize the single-panel control mode, which is not limited in the embodiment.

[0066] More specifically, the double-panel control mode is specifically that each control center 700 respectively exists a corresponding control panel 500, and different control panels 500 can realize independent control of different music seat bodies 100 or different combinations of music seat bodies 100, which is beneficial to improve the control flexibility of different music seat bodies 100 or different combinations of music seat bodies 100, and different control panels 500 can also realize cooperative control / synchronous control of different music seat bodies 100 or different combinations of music seat bodies 100, which is beneficial to improve the cooperative control convenience of multiple music seat bodies 100. Taking the sofa shown in Figure 9 as an example, Figure 9 the sofa in the figure has two different control panels 500, assuming that the second interface P2 is used to realize the double-panel control mode and the third interface P3 is used to realize the single-panel control mode, the principle diagram corresponding to the double-panel control mode can be as shown in Figure 13 , wherein the two control centers 700 are connected through the first interface P1 and the second interface P2. If the consumer wants to remove the control panel corresponding to the control center 700 connected with the second interface P2, the control center 700 originally connected with the second interface P2 can be directly adjusted to be connected with the third interface P3. Further, in the double-panel control mode, if independent control of different combinations of music seat bodies 100 is realized, when the control center 700 connected with the second interface P2 receives the music control signal sent by the control center 700 connected with the first interface P1, the control center 700 connected with the second interface P2 does not respond to the aforementioned music control signal, and vice versa, that is, if the control center 700 connected with the first interface P1 receives the music control signal sent by the control center 700 connected with the second interface P2, the control center 700 connected with the first interface P1 does not respond to the aforementioned music control signal. If cooperative control of different combinations of music seat bodies 100 is realized, when the control center 700 connected with the second interface P2 receives the music playing control signal sent by the control center 700 connected with the first interface P1, the control center 700 connected with the second interface P2 responds to the aforementioned music control signal, and vice versa, that is, if the control center 700 connected with the first interface P1 receives the music playing control signal sent by the control center 700 connected with the second interface P2, the control center 700 connected with the first interface P1 responds to the aforementioned music control signal.

[0067] More specifically, the single-panel control mode is specifically that one control panel 500 is used to realize synchronous control of the sound 4, the first vibrator 5 and the second vibrator 6 in multiple music seat bodies 100 of the sofa, which is beneficial to improve the control convenience and control efficiency of multiple music seat bodies 100. Taking the sofa shown in Figure 10 as an example, Figure 10The sofa in the figure has only one control panel 500, assuming that the second interface P2 is used to realize the double-panel control mode and the third interface P3 is used to realize the single-panel control mode, the principle diagram corresponding to the single-panel control mode can be as shown in the figure Figure 14 If the consumer wants to increase the control panel corresponding to the control center 700 connected with the third interface P3, the control center originally connected with the third interface P3 can be directly adjusted to be connected with the second interface P2. Further, in the single-panel control mode, when the control center 700 connected with the third interface P3 receives the music control signal sent by the control center 700 connected with the first interface P1, the control center 700 connected with the third interface P3 responds to the music control signal, and vice versa, that is, when the control center 700 connected with the first interface P1 receives the music control signal sent by the control center 700 connected with the third interface P3, the control center 700 connected with the first interface P1 responds to the music control signal.

[0068] It can be seen that the optional embodiment can realize flexible selection and adjustment between different panel control modes through the Y-shaped connection line 600, that is, realize flexible selection and adjustment of the control panel 500 used to actually control the music seat body 100, which is beneficial to improve the use experience of the consumer for the sofa.

[0069] It should be particularly pointed out that: Figures 13-14 The control center 700, the Y-shaped connection line 600 and the control panel 500 are only exemplarily and schematically drawn, and other components included in the sofa are not shown in the figure. Figures 13-14
