In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0033] See also Figure 1-3 , an embodiment of the present invention provides an audio device, including an audio body 100 and a transmission mechanism.

[0034] The transmission mechanism includes a fixed frame 10 and a transmission frame 20, and the transmission frame 20 includes a first rotating rod 21, a second rotating rod 22 and a connecting rod 23. One end of the first rotating rod 21 and the second rotating rod 22 are respectively rotatably connected to the fixed frame 10, and the other end is respectively rotatably connected to the connecting rod 23. The first rotating rod 21 and the second rotating rod 22 are parallel to each other and have equal effective lengths. The connecting rod 23 is fixedly connected to the audio body 100.

[0035] In actual application, the fixing frame 10 is fixedly installed on the rear side of the flat-screen TV 200, the transmission frame 20 is installed on the side of the fixing frame 10 away from the flat-screen TV 200, and the first rotating rod 21 and the second rotating rod 22 are respectively rotatably connected to the fixing frame 10 and the connecting rod 23, that is, the transmission frame 20 forms a parallel double crank structure, so that the sound body 100 can be translated around the flat-screen TV 200 in an arc trajectory through the action of the transmission frame 20; for example, Figure 2 As shown, when the sound body 100 needs to be used, the driving frame 20 is used to make the sound body 100 move downward in an arc trajectory to achieve expansion, so that the sound body 100 is placed side by side below the flat-screen TV 200, and its sound output surface faces the same direction as the display surface of the flat-screen TV 200, so that music and film and television sounds with better sound quality can be played; Figure 3 As shown, when the audio body 100 is not needed, the audio body 100 can be moved upward and folded in an arc trajectory by the action of the transmission frame 20, and then the audio body 100 can be fixed by a locking device to be hidden behind the flat-screen TV 200. At this time, the diaphragm sound outlet surface of the audio body 100 faces the rear side of the flat-screen TV 200, thereby protecting the audio body 100 without affecting the beautiful appearance of the flat-screen TV 200. The structure is simple, the rotation performance is stable, and the cost is low.

[0036] Of course, the location of the transmission mechanism is not limited to Figure 2 and Figure 3 The audio body 100 shown is located below the flat-screen TV 200 when unfolded; in other embodiments, the audio body 100 can also be arranged to be located on the left and right sides or the top of the flat-screen TV 200 when unfolded, and when arranged to be unfolded and located on both sides, it does not require a locking device in both the unfolded state and the folded state. Preferably, a damping structure can be set between the fixed frame 10 and the transmission frame 20 at this time.

[0037] Furthermore, in order to make the audio body 100 more compatible and beautiful with the flat-screen TV 200 when in the unfolded state, the length of the audio body 100 can be the same as the length or width corresponding to the electrical properties of the flat-screen TV; in the present embodiment, there are two transmission frames 20, and the two transmission frames 20 are arranged at intervals along the length direction of the audio body 100; thereby obtaining just the right connection strength between the fixing frame 10 and the audio body 100.

[0038] In one embodiment, the fixing frame 10 includes a back plate 11 and two fixing parts 12 fixed to one side of the back plate 11 and spaced apart. A rotating shaft 13 is rotatably arranged between the two fixing parts 12. The axial direction of the rotating shaft 13 is parallel to the length direction of the sound body 100. One end of each of the two first rotating rods 21 is fixedly connected to the rotating shaft 13; one end of each of the two second rotating rods 22 is rotatably mounted on the two fixing parts 12 in a one-to-one correspondence. In this way, the two transmission frames 20 are connected by the rotating shaft 13, so that the two transmission frames 20 are kept synchronous during the rotation process, so that the sound body 100 is kept stable during the translation process in an arc trajectory; in addition, the shape of the back plate 11 is similar to the shape of the back of the flat-screen TV 200, so that the back plate 11 can be installed on the back of the flat-screen TV 200 in a close fit, so that the assembly of the fixing frame 10 and the flat-screen TV 200 is more stable and reliable.

[0039] In one embodiment, the audio device further includes a driving mechanism 30 mounted on the fixing frame 10, the driving mechanism 30 is in transmission connection with the rotating shaft 13, and is used to drive the rotating shaft 13 to rotate, so that the first rotating rod 21 rotates synchronously, and the audio body 100 is driven to move between the unfolded position and the folded position through the connecting rod 23. In this way, the audio body 100 is electrically switched through the driving mechanism 30, and the consumer does not need to manually unfold or fold the audio body 100, which is more convenient to use.

[0040] Specifically, the driving mechanism 30 includes a motor base 31 fixed on the back plate 11, a driving motor 32 mounted on the motor base 31, and a driving gear 33 mounted on the output shaft of the driving motor 32; a driven gear 14 meshing with the driving gear 33 is fixed on the middle part of the rotating shaft 13. In this embodiment, the driving motor 32 can be a servo motor or a stepper motor according to actual needs. The output shaft of the driving motor 32 is perpendicular to the rotating shaft 13. The driving gear 33 and the driven gear 14 are both bevel gear structures. When the output shaft of the driving motor 32 rotates forward, the rotating shaft 13 is driven to rotate along the first direction through the cooperation of the driving gear 33 and the driven gear 14, thereby driving the first rotating rod 21 to rotate a set angle, and then the sound body 100 is translated from the folded state to the unfolded state in an arc trajectory through the connecting rod 23; when the output shaft of the driving motor 32 is reversed, the rotating shaft 13 is driven to rotate along the second reverse direction, so that the sound body 100 is translated from the unfolded state to the folded state in an arc trajectory.

[0041] In one embodiment, the audio device further includes a switch electrically connected to the driving mechanism 30, and the switch is used to control the driving mechanism 30 to drive the audio body to switch between the unfolded position and the folded position. The switch can be a manual switch, which is set on the fixing frame 10, the back of the flat-screen TV 200 or other similar hidden positions. When the state of the audio body 100 needs to be switched, the switch is manually operated to enable the driving mechanism 30 to switch the state of the audio body 100.

[0042] In other embodiments, the switching switch may also be an electric control switch, which may be connected to the control mainboard of the flat-panel TV 200 by signal; illustratively, when the flat-panel TV 200 is turned on, the control mainboard of the flat-panel TV 200 sends a first signal to the switching switch, so that the driving structure drives the transmission mechanism to drive the audio body 100 from the folded position to the unfolded position; when the flat-panel TV 200 is turned off, the control mainboard of the flat-panel TV 200 sends a second signal to the switching switch, so that the driving mechanism 30 drives the transmission mechanism to drive the audio body 100 from the unfolded position to the folded position; in this way, the state switching of the audio body 100 is made more intelligent. Of course, the switching switch may also be connected to a smart phone or a remote control by wireless connection, and the state switching of the audio body 100 may be controlled by a device such as a smart phone or a remote control.

[0043] In one embodiment, the audio device further includes a limiting structure 40, which is used to limit the moving range of the audio body driven by the driving mechanism 30, so that the audio body can only move within the range between the unfolded position and the folded position. The limiting structure 40 can prevent the transmission mechanism from rotating beyond the stroke under the action of the driving mechanism 30 and colliding with the flat-screen TV 200, thereby ensuring the safe operation of the transmission mechanism.

[0044] Specifically, the limit structure 40 includes two limit sensors 41 fixed on the back plate 11 and a limit sensing component 42 fixed on the rotating shaft 13. The two limit sensors 41 are respectively located on opposite sides of the rotating shaft 13 and are connected to the drive mechanism 30 by signal. The limit sensing component 42 can rotate within the range between the two limit sensors 41 under the drive of the rotating shaft 13.

[0045] In this embodiment, the limit sensor 41 includes but is not limited to sensors of the type of photoelectric sensors, Hall sensors or proximity switches. When the limit sensor 42 rotates to cooperate with the limit sensor 41 located above the rotating shaft 13, the limit sensor 41 generates a limit signal to the drive mechanism 30 to stop the drive motor 32 from rotating. At this time, the audio body 100 stops in the folded state; when the limit sensor 42 rotates to cooperate with the limit sensor 41 located below the rotating shaft 13, the limit sensor 41 generates a limit signal to the drive mechanism 30 to stop the drive motor 32 from rotating. At this time, the audio body 100 stops in the unfolded state; in this way, it can be ensured that the transmission mechanism can only rotate within the set range under the action of the drive mechanism 30, so that the audio body 100 can be accurately positioned in the unfolded position and the folded position.

[0046] In one embodiment, the audio device further includes a mounting frame 50, the mounting frame 50 includes a base 51, a support plate 52 fixed at the lower end on the base 51, and a connecting plate 53 fixed at one end to the support plate 52, and the other end of the connecting plate 53 is fixed to the upper end of the back plate 11 of the fixing frame 10, so that the back plate 11 of the fixing frame 10 and the support plate 52 are spaced from each other, and the transmission frame 20 is located between the back plate 11 of the fixing frame 10 and the support plate 52. In this way, the flat-screen TV 200, the audio body 100, the transmission mechanism and the driving mechanism 30 can be supported and fixed by the mounting frame 50, so that the overall structure is simple, the cost is low, and it is easy to maintain; of course, in other embodiments, the fixing frame 10 can also be installed on the wall using a wall-mounted structure, and the present invention does not make any special restrictions on this. In the above embodiments, the description of each embodiment has its own emphasis, and the part that is not described in detail in a certain embodiment can refer to the relevant description of other embodiments.

[0047] The above is a description of the technical solution provided by the present invention. For those skilled in the art, according to the ideas of the embodiments of the present invention, there may be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present invention.
