[0033] Please also read Figures 1 to 4 An embodiment of the present application provides an audio device, including a stacked signal distributor 100 and a power distributor 200, the signal distributor 100 is electrically connected to the power distributor 200, a threaded hole 101 is provided on the side of the signal distributor 100 facing the power distributor 200, the power distributor 200 includes a main body 10, a guide sleeve 20 and a threaded connector 30, the main body 10 has a first cover plate 11 and a second cover plate 12 arranged relatively spaced apart, the first cover plate 11 is provided with a through hole 111, the through hole 111 corresponds to the threaded hole 101, the guide sleeve 20 is arranged on the second cover plate 12, one end of the threaded connector 30 is confined in the guide sleeve 20, the threaded connector 30 can rotate around its own axis and move along the axial direction of the guide sleeve 20, the other end of the threaded connector 30 is used to pass through the through hole 111 and then be threadedly connected with the threaded hole 101.

[0034] The signal distributor 100 is stacked with the power distributor 200, and the through hole 111 is aligned with the threaded hole 101. Then the threaded connector 30 is moved along the axial direction of the guide sleeve 20, and the threaded connector 30 is rotated at the same time, so that the threaded connector 30 passes through the through hole 111 and is threadedly connected with the threaded hole 101, thereby achieving the fixation of the signal distributor 100 and the power distributor 200. The signal distributor 100 and the power distributor 200 are stably connected and are not prone to shaking during transportation, thereby improving portability.

[0035] It should be noted that the end of the guide sleeve 20 away from the second cover plate 12 is directly opposite to the through hole 111, and the axis of the threaded connector 30 coincides with the axis of the guide sleeve 20, so that the threaded connector 30 can accurately pass through the through hole 111 by moving in a straight line along the axial direction of the guide sleeve 20. In addition, one end of the threaded connector 30 is limited in the guide sleeve 20, which means that during the movement of the threaded connector 30, the end of the threaded connector 30 close to the second cover plate 12 is always located in the guide sleeve 20 and will not be separated from the guide sleeve 20, so that the guide sleeve 20 can continue to guide the movement of the threaded connector 30, ensuring that the threaded connector 30 accurately passes through the through hole 111 and then is threadedly connected with the threaded hole 101.

[0036] Specifically, the power distributor 200 and the signal distributor 100 are stacked in sequence from bottom to top. The first cover plate 11 of the power distributor 200 is located above the second cover plate 12, serving as the top plate of the main body 10, and the second cover plate 12 of the power distributor 200 is located below the first cover plate 11, serving as the bottom plate of the main body 10. The guide sleeve 20 is vertically arranged to limit the shaking of the threaded connector 30 in the four directions of front, back, left and right, and ensure that the threaded connector 30 stably moves in a straight line in the up and down directions.

[0037] The signal distributor 100 is an electronic device used to distribute an audio signal to multiple output channels. It can be a simple analog circuit or a complex digital processing device. Its purpose is to ensure that the audio signal can be received and played by multiple devices. In the audio field, the signal distributor 100 is generally used in music performances, studio recordings, radio stations, and other occasions where audio signals need to be distributed to multiple target devices. The signal distributor 100 usually has multiple input and multiple output ports. The user can select the input source as needed and distribute the signal to one or more output channels. The function of the signal distributor 100 is not only to copy the signal to multiple channels, it may also include functions such as signal amplification, isolation, mixing, balancing, etc. to ensure that each output channel can obtain a stable and high-quality audio signal.

[0038] The power distributor 200 is a device for managing and distributing power supply. In the audio field, the power distributor 200 is usually used to provide power to multiple audio devices to ensure that they can operate normally. The power distributor 200 usually has multiple input and multiple output ports, which can obtain power from one or more power sources and distribute it to multiple audio devices. These devices may include audio amplifiers, mixers, effects, recording equipment, etc. The power distributor 200 usually includes functions such as overload protection and short circuit protection to prevent power overload or other problems from damaging the equipment.

[0039] In one embodiment, Figure 4 As shown, the second cover plate 12 is provided with a fixing hole 121, and an internal thread is provided in the fixing hole 121. Other audio devices can also be stacked below the power distributor 200, and the power distributor 200 can be threadedly connected with the audio device below through the internal thread of the fixing hole 121.

[0040] In one embodiment, Figure 3 As shown, the main body 10 further includes a side panel 13, which is disposed between the first cover plate 11 and the second cover plate 12, and cooperates with the first cover plate 11 and the second cover plate 12 to form a receiving cavity 14, the edge of the first cover plate 11 extends out of the side panel 13 to form a first mounting portion 112, the through hole 111 is disposed in the first mounting portion 112, the edge of the second cover plate 12 extends out of the side panel 13 to form a second mounting portion 122, and the guide sleeve 20 is disposed on the second mounting portion 122. The guide sleeve 20 and the threaded connector 30 are installed between the first mounting portion 112 and the second mounting portion 122, that is, located outside the receiving cavity 14, so as to facilitate the connection operation between the signal distributor 100 and the power distributor 200. Specifically, there are four first mounting parts 112, which are respectively located at the four corners of the first cover plate 11, and there are four second mounting parts 122, which are respectively located at the four corners of the second cover plate 12 and are grouped in a one-to-one correspondence with the four first mounting parts 112. A guide sleeve 20 and a threaded connector 30 are provided between each group of first mounting parts 112 and second mounting parts 122. The four corners of the power distributor 200 are respectively connected and fixed to the four corners of the signal distributor 100 by four threaded connectors 30, thereby improving the connection stability and reliability.

[0041] In one embodiment, Figure 4As shown, the length of the threaded connector 30 is greater than the length of the guide sleeve 20, and the power distributor 200 further includes a knob 40, which is fixedly sleeved on the portion of the threaded connector 30 extending outside the guide sleeve 20, and the threaded connector 30 can drive the knob 40 to move, so that the knob 40 abuts against the first cover plate 11. During operation, the operator grabs the knob 40 by hand, and drives the threaded connector 30 to move linearly and rotate through the knob 40, so that the threaded connector 30 passes through the through hole 111 and then is spirally inserted into the threaded hole 101 until the knob 40 abuts against the first cover plate 11, so that the first cover plate 11 and the signal distributor 100 are tightly fitted, thereby achieving the fixation of the signal distributor 100 and the power distributor 200. When the knob 40 abuts against the first cover plate 11, the end of the threaded connector 30 close to the second cover plate 12 is still located in the guide sleeve 20, so that one end of the threaded connector 30 is limited in the guide sleeve 20. Specifically, the knob 40 is cylindrical, which is convenient for the operator to hold. The surface of the knob 40 is provided with anti-slip texture, which can enhance friction and facilitate rotation. The knob 40 is provided with an inner hole, and the hole wall of the inner hole is provided with an internal thread, which cooperates with the external thread of the threaded connector 30, thereby achieving the fixation of the knob 40 and the threaded connector 30.

[0042] In one embodiment, Figure 4 As shown, when the knob 40 abuts against the guide sleeve 20, the end of the threaded connector 30 extending out of the guide sleeve 20 is located in the through hole 111. Since the end of the threaded connector 30 away from the guide sleeve 20 is already located in the through hole 111 when the knob 40 abuts against the guide sleeve 20, the threaded connector 30 can keep penetrating the through hole 111 during the movement, avoiding the situation where the threaded connector 30 is not aligned with the through hole 111 and cannot enter the through hole 111, ensuring that the threaded connector 30 can smoothly pass through the through hole 111 and then be threadedly connected with the threaded hole 101, thereby improving the reliability of the work.

[0043] In one embodiment, Figure 4As shown, a stop groove 41 is provided at one end of the knob 40 facing the guide sleeve 20, and an end of the guide sleeve 20 away from the second cover plate 12 is inserted into the stop groove 41. By providing the stop groove 41 on the knob 40 and inserting the guide sleeve 20 into the stop groove 41, the axial movement of the knob 40 along the guide sleeve 20 can be limited, and the rotation of the knob 40 around the axis of the guide sleeve 20 can be limited, so that the knob 40 is more stable and not easy to shake during the movement and rotation process, thereby ensuring that the threaded connector 30 can stably move along the axial direction of the guide sleeve 20 to accurately pass through the through hole 111 and then be threadedly connected with the threaded hole 101. In addition, in the limited installation space between the first cover plate 11 and the second cover plate 12, by providing the stop groove 41 on the knob 40, the knob 40 can be sleeved on the guide sleeve 20 through the stop groove 41, thereby increasing the length of the knob 40 for the convenience of the operator to grasp and rotate.

[0044] In one embodiment, when the knob 40 abuts against the guide sleeve 20, the distance between the knob 40 and the first cover plate 11 is less than the depth of the limiting groove 41. When the knob 40 abuts against the guide sleeve 20, the distance between the knob 40 and the first cover plate 11 is the largest, and when the knob 40 abuts against the first cover plate 11, the distance between the knob 40 and the first cover plate 11 is zero. Since the maximum distance between the knob 40 and the first cover plate 11 is less than the depth of the limiting groove 41, during the movement of the knob 40, the guide sleeve 20 can remain inserted into the limiting groove 41 and will not fall out of the limiting groove 41, thereby continuously guiding the knob 40.

[0045] In one embodiment, in combination Figure 4 and Figure 5 As shown, the guide sleeve 20 includes a first sleeve portion 21 and a second sleeve portion 22. The first sleeve portion 21 is inserted into the limiting groove 41. The two ends of the second sleeve portion 22 are respectively connected to the first sleeve portion 21 and the second cover plate 12. The outer diameter of the second sleeve portion 22 is larger than the outer diameter of the first sleeve portion 21. The end surface of the second sleeve portion 22 connected to one end of the first sleeve portion 21 is used to abut against the knob 40. When disassembling the signal distributor 100 and the power distributor 200, the knob 40 and the threaded connector 30 are moved toward the direction close to the second cover plate 12, and the distance between the knob 40 and the second sleeve portion 22 is observed. When the knob 40 fits the end surface of the second sleeve portion 22, it means that the threaded connector 30 has moved to the position closest to the second cover plate 12. It can be judged that the end of the threaded connector 30 away from the second cover plate 12 has completely withdrawn from the threaded hole 101. At this time, the signal distributor 100 and the power distributor 200 can be separated smoothly, and the operation is very convenient.

[0046] In one embodiment, in combination Figure 4 and Figure 5As shown, the power distributor 200 further includes an annular cover plate 50 and a compression spring 60. The annular cover plate 50 is arranged at one end of the guide sleeve 20 away from the second cover plate 12. The threaded connector 30 includes a head 31 and a rod 32. The head 31 is arranged in the guide sleeve 20. The rod 32 passes through the annular cover plate 50. One end of the rod 32 is connected to the head 31. The other end of the rod 32 is used to pass through the through hole 111. The compression spring 60 is sleeved on the rod 32. The two ends of the compression spring 60 are respectively in contact with the head 31 and the annular cover plate 50. The compression spring 60 can apply a thrust directed to the second cover plate 12 to the head 31 of the threaded connector 30, thereby pressing the head 31 of the threaded connector 30 against the second cover plate 12, and plays an axial positioning role on the threaded connector 30. When the power distributor 200 is carried alone, the threaded connector 30 can be prevented from jumping up and down, thereby avoiding the noise generated by the collision of the threaded connector 30 with other components. Specifically, an end of the rod portion 32 away from the head portion 31 is provided with an external thread for threaded connection with the threaded hole 101 .

[0047] In one embodiment, Figure 4 As shown, a locking protrusion 123 is provided on the side of the second cover plate 12 facing the guide sleeve 20, and a locking groove 311 is provided on the head 31 of the threaded connector 30, and the locking protrusion 123 is inserted into the locking groove 311. Through the cooperation between the locking protrusion 123 and the locking groove 311, the positioning effect of the threaded connector 30 can be enhanced.

[0048] In one embodiment, in combination Figure 4 and Figure 5 As shown, the rod 32 of the threaded connector 30 includes an optical axis section 321 and a threaded section 322. The optical axis section 321 is penetrated by the annular cover plate 50 and extends into the guide sleeve 20 to be connected with the head 31. The threaded section 322 is located outside the guide sleeve 20 and connected to the end of the optical axis section 321 away from the head 31. The end of the threaded section 322 away from the optical axis section 321 is used for threaded connection with the threaded hole 101. The surface of the optical axis section 321 is smooth, which is convenient for the optical axis section 321 to slide in the inner hole of the annular cover plate 50. The surface of the threaded section 322 is provided with an external thread, which can cooperate with the internal thread of the threaded hole 101. Specifically, the knob 40 is threadedly sleeved on the threaded section 322 to achieve the fixation between the knob 40 and the threaded connector 30. In order to prevent the knob 40 from loosening, glue can be applied at the connection between the knob 40 and the threaded section 322 to bond the knob 40 and the threaded connector 30 as a whole.

[0049] In one embodiment, in combination Figure 2 and Figure 3As shown, the signal distributor 100 is provided with a positioning groove 102, and the power distributor 200 is provided with a positioning protrusion 15, and the positioning protrusion 15 is plugged into the positioning groove 102. When the signal distributor 100 and the power distributor 200 are stacked, the positioning protrusion 15 of the power distributor 200 is inserted into the positioning groove 102 of the signal distributor 100, so as to realize the positioning of the signal distributor 100 and the power distributor 200. By positioning, the through hole 111 is aligned with the threaded hole 101, and then the threaded connector 30 can be passed through the through hole 111 and then threadedly connected with the threaded hole 101, which is very convenient to operate. Specifically, the positioning protrusion 15 is arranged on the side of the first cover plate 11 facing away from the second cover plate 12. Of course, in some other embodiments, the positioning protrusion 15 can be arranged on the signal distributor 100 in reverse, and the positioning groove 102 can be arranged on the power distributor 200 in reverse. Specifically, there are multiple positioning protrusions 15 , and the number of positioning grooves 102 is consistent with the number of positioning protrusions 15 . The multiple positioning protrusions 15 are plugged into the multiple positioning grooves 102 in a one-to-one correspondence to enhance the positioning effect.

[0050] In one embodiment, the positioning protrusion 15 is magnetically connected to the positioning groove 102. On the basis of the insertion of the positioning protrusion 15 and the positioning groove 102, the signal distributor 100 and the power distributor 200 can be adsorbed and fixed together by making the positioning protrusion 15 and the positioning groove 102 magnetically connected. In addition, when the positioning protrusion 15 is close to the positioning groove 102, the positioning protrusion 15 can automatically fall into the positioning groove 102 under the action of the magnetic force, thereby quickly achieving positioning.

[0051] In one embodiment, the positioning protrusion 15 is covered with a protective cover. By covering the positioning protrusion 15 with the protective cover, when the positioning protrusion 15 is inserted into the positioning groove 102, it can play a certain buffering and protective role, avoiding the positioning protrusion 15 from hard collision with the positioning groove 102, thereby improving the service life. In addition, the power distributor 200 can be turned over and placed on the desktop, and the positioning protrusion 15 supports the power distributor 200 as a whole, and the positioning protrusion 15 is covered with a protective cover, which can avoid the positioning protrusion 15 from directly contacting the desktop, and protect the positioning protrusion 15 and the desktop. Specifically, the protective cover can be a leather cover, a rubber cover, a silicone cover, a sponge cover, etc.

[0052] In one embodiment, in combination Figure 2 and Figure 3As shown, the power distributor 200 is provided with a first electrical connector 16, and the signal distributor 100 is provided with a second electrical connector 103. The first electrical connector 16 is docked and electrically connected with the second electrical connector 103. By docking the first electrical connector 16 with the second electrical connector 103, the power distributor 200 and the signal distributor 100 can be electrically connected, so that the power distributor 200 can supply power to the signal distributor 100. Specifically, one of the first electrical connector 16 and the second electrical connector 103 is an electrical plug, and the other is an electrical socket.

[0053] In one embodiment, the signal distributor 100 includes a body, a limiting sleeve and a threaded fastener. The body has a third cover plate and a fourth cover plate that are relatively spaced apart. The fourth cover plate is provided with a threaded hole 101, the third cover plate is provided with a connecting hole, the limiting sleeve is provided on the fourth cover plate, one end of the threaded fastener is limited in the limiting sleeve, the threaded fastener can rotate around its own axis and move along the axis of the limiting sleeve, and the other end of the threaded fastener is used to pass through the connecting hole. Other audio devices can also be stacked above the signal distributor 100, so that the threaded fastener moves along the axial direction of the limiting sleeve, and the threaded fastener is rotated at the same time, so that the threaded fastener passes through the connecting hole and is threadedly connected to the audio device above, thereby achieving the fixation of the signal distributor 100 and the audio device above.

[0054] Specifically, the limit sleeve has the same structure as the guide sleeve 20, and the threaded fastener has the same structure as the threaded connector 30. The features of the limit sleeve not explained in this embodiment can be explained by the guide sleeve 20, and the features of the threaded fastener not explained in this embodiment can be explained by the threaded connector 30, which will not be repeated here.

[0055] The above are only preferred embodiments of the present application and are not intended to limit the present application.
