[0026] The present invention will now be described in further detail with reference to the accompanying drawings.
[0027] The following is in conjunction with the appendix Figure 1 , 3 As detailed in 5-10, a portable speaker includes a central screw 101 and a support plate 102 threadedly connected to the central screw 101. The support plate 102 is rotatably connected to a plurality of hinged seats 103 via shafts. Each of the plurality of hinged seats 103 is fixedly connected to a vertical support plate 104 by welding. Each of the plurality of vertical support plates 104 is fixedly connected to a speaker 105 via a flange plate.
[0028] Furthermore, the central screw 101 provides space for connecting the supporting horizontal plate 102, and the central screw 101 is provided with repetitive threads. When the supporting horizontal plate 102 rotates on the central screw 101, the supporting horizontal plate 102 will repeatedly slide up and down. The supporting horizontal plate 102 provides rotational space for multiple hinged seats 103, and the multiple hinged seats 103 provide fixed space for multiple vertical support plates 104, which in turn provide fixed space for multiple horns 105. A rechargeable battery pack and a receiving module are installed on the supporting horizontal plate 102, and the battery pack provides power support for the receiving module. To ensure the normal operation of the receiving module, the receiving module is connected to multiple speakers 105 via wires. The mobile phone can connect to the receiving module via Bluetooth, and then play music from the mobile phone. The music will be transmitted to the multiple speakers 105 through the receiving module, and the multiple speakers 105 will play the music. When the multiple speakers 105 are playing music, the supporting plate 102 can be rotated. Then the supporting plate 102 will drive the multiple speakers 105 to rotate and move up and down. At this time, the music will be emitted through the multiple speakers 105 while rotating and moving up and down, thereby enhancing the sound quality of the music, producing surround sound, and ensuring that people can hear pleasant music.
[0029] The following is in conjunction with the appendix Figure 1 , 3 Detailed descriptions of sections 5, 6, and 8-10: Each of the multiple hinged connecting seats 103 is fixedly connected to a linkage gear 201 by welding; a multiple lifting rack 202 is evenly slidably connected to the supporting horizontal plate 102 by a keyway; and the multiple lifting racks 202 are respectively meshed with and connected to the multiple linkage gears 201 for transmission.
[0030] Furthermore, multiple linkage gears 201 can drive multiple hinged connecting seats 103 to rotate, thereby driving multiple speakers 105 to rotate through multiple vertical support plates 104, thus changing the angle of multiple speakers 105. This ensures that while multiple speakers 105 move up and down while rotating, they also generate an up and down tilt angle, further improving the sound quality of music produced by multiple speakers 105. The lifting and lowering of multiple lifting racks 202 can drive multiple linkage gears 201 to rotate, ultimately achieving the change of the up and down tilt angle of multiple speakers 105.
[0031] The following is in conjunction with the appendix Figure 1 , 3 Detailed descriptions of sections 5, 6, and 8-10: Multiple bearing seats 301 are fixedly connected to the supporting horizontal plate 102 by welding. Each bearing seat 301 is fixedly connected to a geared motor I302 via a flange plate. Each bearing seat 301 is rotatably connected to a lifting screw 303 via bearing holes. The lifting screws 303 are fixedly connected to the output shafts of the geared motors I302 via keyways and snap rings. The lifting screws 303 are also connected to the lifting racks 202 via threaded transmission.
[0032] Furthermore, multiple bearing seats 301 provide fixed space for multiple geared motors I302 and rotational space for multiple lifting screws 303. Activating the multiple geared motors I302 drives the multiple lifting screws 303 to rotate. The lifting screws 303 are equipped with reciprocating threads. When the multiple lifting screws 303 rotate, they drive multiple lifting racks 202 to move up and down cyclically, thereby driving multiple linkage gears 201 to rotate, completing the change of the up and down tilt angle of multiple horns 105. All multiple geared motors I302 are connected to the rechargeable... The battery pack is connected by wires to provide power to multiple geared motors I302, ensuring their normal operation. The multiple geared motors I302 are fixed relative to the supporting plate 102, preventing wire entanglement. When the supporting plate 102 rotates, the multiple geared motors I302 are also activated, allowing the multiple speakers 105 to rotate and rise simultaneously while also changing their tilt angle. This ensures that the multiple speakers 105 can simultaneously complete rotation, rising, falling, and tilt angle changes, producing a more immersive surround sound and improving the sound quality of the audio system.
[0033] The following is in conjunction with the appendix Figure 1 , 3 As detailed in section 5-7, multiple fixed support rods 401 are uniformly and fixedly connected to the central screw 101 by welding. All the multiple fixed support rods 401 are fixedly connected to the threaded vertical cavity 402 by welding. The threaded vertical cavity 402 is fixedly connected to the supporting base plate 403 by welding.
[0034] Furthermore, the supporting base plate 403 serves as a load-bearing connection, providing a fixed space for the threaded vertical cavity 402. The threaded vertical cavity 402 provides a fixed space for multiple fixed support rods 401, which in turn fix the central screw 101, ensuring that the central screw 101 does not rotate arbitrarily. Only when the central screw 101 is fixed can the supporting horizontal plate 102 move up and down while rotating, thereby producing better sound quality.
[0035] The following is in conjunction with the appendix Figure 1 , 3 As detailed in section 5-7, the supporting horizontal plate 102 is slidably connected to multiple linkage cylinders 501 through multiple round holes, and a cross support plate 502 is fixedly connected to the bottom of the multiple linkage cylinders 501 by welding.
[0036] Furthermore, the rotation of multiple linkage cylinders 501 can drive the support plate 102 to rotate, ensuring that the support plate 102 moves up and down while rotating. The cross support plate 502 can fix the multiple linkage cylinders 501 together, ensuring that the multiple linkage cylinders 501 can rotate at the same speed, and ensuring that the support plate 102 can rotate smoothly.
[0037] The following is in conjunction with the appendix Figure 1 , 3 As detailed in section 5-7, a geared motor II601 is fixedly connected to the support base plate 403 via a flange plate, and the output shaft of the geared motor II601 is fixedly connected to the cross support plate 502 via a keyway and a snap ring.
[0038] Furthermore, another rechargeable battery pack is fixedly connected to the base plate 403. This battery pack can provide power to the geared motor II601, ensuring that the geared motor II601 can start normally. After the geared motor II601 is started, it can drive the cross support plate 502 to rotate, and finally drive multiple linkage cylinders 501 to rotate.
[0039] The following is in conjunction with the appendix Figure 1 , 3 As detailed in section 4, the threaded vertical cavity 402 is connected to an outer protective cavity 701 by a thread, and the outer protective cavity 701 is uniformly provided with a plurality of through circular holes 702.
[0040] Furthermore, the outer protective cavity 701 can be used to protect the above-mentioned parts, preventing them from being damaged by collisions. The sound generated by the multiple speakers 105 can be discharged through the multiple through holes 702, ensuring that the music produced can be heard by people. Moreover, the outer protective cavity 701 is easy to disassemble, allowing for the replacement and maintenance of parts.
[0041] The following is in conjunction with the appendix Figure 1 , 3 In detail in section 4, a lifting slide plate 801 is slidably connected to the outer protective cavity 701 via a key and a keyway, and an adjusting screw 802 is rotatably connected to the outer protective cavity 701 via a bearing hole. The adjusting screw 802 and the lifting slide plate 801 are connected by a threaded transmission.
[0042] Furthermore, the lifting slide plate 801 and the outer protective cavity 701 are slidably connected by a key and a keyway. By sliding the lifting slide plate 801 within the outer protective cavity 701, the space within the outer protective cavity 701 is changed. The different remaining space within the outer protective cavity 701 will result in different sound quality produced by the multiple speakers 105. Rotating the adjusting screw 802 can drive the lifting slide plate 801 to rise or fall, thereby changing the remaining space within the outer protective cavity 701.
[0043] The following is in conjunction with the appendix Figure 1 and 2 In detail, the supporting base plate 403 is slidably connected to multiple limiting slide columns 901 through multiple round holes. Each limiting slide column 901 is fitted with a shock-absorbing spring 902. Each limiting slide column 901 is connected to a fastening nut 903 through a thread. The multiple limiting slide columns 901 are fixedly connected to the moving vehicle plate 904 by welding.
[0044] Furthermore, the movable platform 904 provides a fixed space for multiple limiting slide columns 901, which in turn provide a sliding space for the supporting base plate 403 and limit its movement, preventing it from rotating freely and allowing it to slide only up and down. Multiple shock-absorbing springs 902 provide shock absorption. When the movable platform 904 moves and encounters bumpy road sections, the supporting base plate 403 will rise and fall on the multiple limiting slide columns 901, and the multiple shock-absorbing springs 902 will provide shock absorption, ensuring that the multiple parts on the supporting base plate 403 do not experience excessive bumps, thus providing protection. Multiple fastening nuts 903 limit the supporting base plate 403, preventing it from detaching from the multiple limiting slide columns 901.
[0045] The following is in conjunction with the appendix Figure 1 and 2 In detail, multiple casters 905 are uniformly and fixedly connected to the bottom of the mobile platform 904 by welding, and a push handle 906 is fixedly connected to the mobile platform 904 by welding.
[0046] Furthermore, multiple casters 905 can be used to move the movable platform 904 on the ground, thereby moving the speaker to the desired position. The push handle 906 provides space for both hands to grip, making it easy to exert force to push the device to the desired position. All casters 905 have a self-locking function. When the device is moved to the desired position, the self-locking function of the multiple casters 905 can be activated to fix the device and prevent it from moving randomly.
