Detailed implementation manners

[0018] The present invention will be further described below in conjunction with the drawings and detailed implementation manners.

[0020] It further includes a damping rod 201 and a second spring 202; four damping rods 201 are bolted to the bottom of the speaker 1, and the damping rods 201 are in damping sliding connection with the corresponding connection blocks 8; a second spring 202 is sleeved on each damping rod 201, one end of the second spring 202 is fixedly connected to the speaker 1, and the other end of the second spring 202 is fixedly connected to the corresponding connection block 8.

[0021] It further includes a second handle 203; two second handles 203 are bolted to the top of the speaker 1, and the speaker 1 is lifted manually through the second handles 203 for easy application of force.

[0022] It further includes a first stop rod 204 and a second stop rod 205; two first stop rods 204 are fixedly connected to the upper part inside the square cover 4, the first stop rods 204 are in contact with the speaker 1, the first stop rods 204 are in sliding connection with the corresponding L-shaped rods 3, and the first stop rods 204 are made of wear-resistant material; two second stop rods 205 are fixedly connected to the lower part inside the square cover 4, the second stop rods 205 are in contact with the speaker 1, the second stop rods 205 are in sliding connection with the corresponding L-shaped rods 3, and the second stop rods 205 are made of wear-resistant material. When storing this loudspeaker device, through the cooperation of the square cover 4, the first stop rods 204 and the second stop rods 205, the bell mouth of the square cover 4 is completely covered, preventing dust, impurities and insects from moving to the bell mouth through the gap between the speaker 1 and the square cover 4.

[0023] Each connection block 8 is provided with a groove 93, the groove 93 is a right triangle, and the groove 93 communicates with the corresponding second round hole 92.

[0024] When storing this loudspeaker device, manually pull the first handle 5 horizontally outwards, the first spring 7 is stretched, so that the first round rod 6 moves away from the connection block 8 and stops locking the square cover 4, then manually pull the square cover 4 upwards, and the square cover 4 drives the parts thereon to move upwards until the first round rod 6 is aligned with the first round hole 91, and then manually insert the first round rod 6 into the first round hole 91 to lock the square cover 4. At this time, the square cover 4, the first stop rods 204 and the second stop rods 205 are located outside the mesh cover of the speaker 1, and the mesh cover and the horn structure of the speaker 1 are protected by the square cover 4, that is, the square cover 4 is arranged to be movable up and down. When storing this loudspeaker device, the square cover 4 moves up to the outside of the horn of the speaker 1, and the mesh cover and the horn structure of the speaker 1 are protected by the square cover 4.

[0025] When moving this loudspeaker device, the square cover 4 is locked on the upper side of the speaker 1 to protect the speaker of the speaker 1. At this time, the universal wheels 2 are in contact with the ground, and the operator manually pushes the loudspeaker device to move. With the cooperation of the universal wheels 2, this device can be easily pushed to the designated position. Then, the operator pulls the handle 1 5 and the round rod 1 6 to move, so that the round rod 1 6 moves away from the round hole 1 91 to unlock the square cover 4. Then, the operator drives the square cover 4 and the parts on it to move downward, aligning the round rod 1 6 with the round hole 2 92. Then, the operator inserts the round rod 1 6 into the round hole 2 92 to lock the square cover 4. At this time, the position of the square cover 4 is as Figure 2 and Figure 3 shown. The bottom position of the square cover 4 is lower than that of the universal wheels 2. When this loudspeaker device is placed on the ground, the square cover 4 is in contact with the ground, while the universal wheels 2 are in a suspended state and do not contact the ground, preventing the universal wheels 2 from rolling due to the vibration generated when the speaker 1 plays music, which is beneficial to improving the stability of this loudspeaker device when playing music.

[0026] When the operator locks the square cover 4 under the speaker 1, the speaker 1 needs to be lifted and the round rod 1 6 needs to be aligned with the round hole 2 92, and the operation is complex. Therefore, a groove 93 is opened on the connecting block 8. After the operator pushes this device to the designated position, then the operator pulls the handle 1 5 and the round rod 1 6 to move, so that the round rod 1 6 moves away from the round hole 1 91 to unlock the square cover 4. Then, the operator drives the square cover 4 and the parts on it to move downward until the square cover 4 is in contact with the ground, that is, the lower side of the square cover 4 is flush with the lower side of the universal wheels 2. At this time, the operator stops pulling the handle 1 5, and the first spring 7 rebounds to drive the round rod 1 6 to move, so that the end of the round rod 1 6 moves to the inside of the groove 93 and is located above the round hole 2 92. Then, the operator uses both hands to lift the speaker 1 upward. Under the action of gravity, the square cover 4 remains in contact with the ground, causing the speaker 1 to drive the connecting block 8 to move upward relative to the round rod 1 6. Under the action of the restoring force of the first spring 7, the round rod 1 6 can slide from the groove 93 into the round hole 2 92 to complete the locking operation of the square cover 4. During this process, the operator only needs to lift the speaker 1 to insert the round rod 1 6 into the round hole 2 92, without the need to position the round rod 1 6 and the round hole 2 92 while lifting the speaker 1, improving the convenience.

[0027] When this loudspeaker device is placed on the ground in the Figure 2 state and plays music, it will generate vibration. During the vibration of the speaker 1, the damping rod 201 will move together and compress the second spring 202. Since the connecting block 8 is fixed and the square cover 4 is in a static state, the damping rod 201 slides up and down on the connecting block 8, converting the kinetic energy of the movement of the speaker 1 into frictional heat energy between the damping rod 201 and the connecting block 8, damping the speaker 1 and improving the stability of the speaker 1 to avoid tipping over.

[0028] In summary, the square cover 4 is arranged to be movable up and down. When storing the loudspeaker device, the square cover 4 moves upward to the outside of the speaker of the speaker 1, and the square cover 4 protects the grille and speaker structure of the speaker 1. During the process of the speaker 1 playing music, the square cover 4 can also be used to support the speaker 1, so that the universal wheels 2 are suspended and do not contact the ground, preventing the universal wheels 2 from rolling due to the vibration generated when the speaker 1 plays music, which is beneficial to improving the stability of the loudspeaker device when playing music; by opening a groove 93 in the connecting block 8, a person only needs to lift the speaker 1 to insert the first round rod 6 into the second round hole 92, without the need to perform positioning operations on the first round rod 6 and the second round hole 92 while lifting the speaker 1, improving the convenience.

[0029] Embodiment 2: On the basis of Embodiment 1, as Figures 6 - 10 shown, it further includes a ventilation plate 206 and a linkage unit; four ventilation plates 206 are slidably connected to the square cover 4; a linkage unit is connected to the ventilation plate 206.

[0030] The linkage unit includes a first linkage block 207, a second linkage block 208 and a third spring 209; a first linkage block 207 is bolted to each ventilation plate 206; the cross-section of the first linkage block 207 is an isosceles triangle; four second linkage blocks 208 are bolted to the speaker 1; the cross-section of the second linkage block 208 is an isosceles triangle; the first linkage block 207 and the second linkage block 208 are in contact with each other for driving the ventilation plate 206 to reciprocate horizontally.

[0031] A noise sensor and a controller are integrated inside the speaker 1. The noise sensor and the controller are electrically connected, and the controller is electrically connected to the volume adjustment module inside the speaker 1. The noise sensor transmits the noise level it monitors to the controller. After the controller recognizes it, the controller adjusts the playing volume through the volume adjustment module, enabling the present invention to automatically adjust the playing volume according to the noise level of the surrounding environment (for example, increasing the volume in a noisy environment and decreasing the volume in a quiet environment to ensure the best auditory experience).

[0032] It also includes a buffer component, which includes a piston plate 2010, a second round rod 2011, a third linkage block 2012, and a fourth spring 2013. Two cavities 94 are formed in the square cover 4. Two piston plates 2010 are slidably connected to the square cover 4, and the piston plates 2010 are located inside the corresponding cavities 94. The piston plates 2010 are provided with damping holes with a diameter of 1 mm. Two second round rods 2011 are fixedly connected to each piston plate 2010, and the second round rods 2011 are slidably connected to the square cover 4. All the second round rods 2011 on the same piston plate 2010 are fixedly connected to a third linkage block 2012 together. The upper side of the third linkage block 2012 is provided with an inclined surface, and a part of the inclined surface is located inside the lower edge of the speaker 1. A fourth spring 2013 is sleeved on each second round rod 2011. One end of the fourth spring 2013 is fixedly connected to the square cover 4, and the other end of the fourth spring 2013 is fixedly connected to the corresponding third linkage block 2012.

[0033] It also includes an auxiliary component, which includes a third round rod 2014, a fifth spring 2015, a fourth linkage block 2016, and a fifth linkage block 2017. Two third round rods 2014 are slidably connected to each third linkage block 2012. A fifth spring 2015 is sleeved on each third round rod 2014. One end of the fifth spring 2015 is fixedly connected to the corresponding third linkage block 2012, and the other end of the fifth spring 2015 is fixedly connected to the corresponding third round rod 2014. All the third round rods 2014 on the same third linkage block 2012 are fixedly connected to a fourth linkage block 2016 together. A notch for accommodating the fourth linkage block 2016 is formed in the third linkage block 2012. Two fifth linkage blocks 2017 are bolted to the speaker 1, and the contact surfaces of the fifth linkage blocks 2017 and the corresponding fourth linkage blocks 2016 are both provided with inclined surfaces, and the fifth linkage blocks 2017 are in contact with the corresponding fourth linkage blocks 2016.

[0034] During the process of the speaker 1 playing music, when the square cover 4, the first stop rod 204, and the second stop rod 205 move to the lower side of the speaker 1, they will cover the lower side of the speaker 1, so that an air sandwich is formed between the square cover 4 and the speaker 1. The heat generated by the operation of the speaker 1 will accumulate in the air sandwich and is difficult to dissipate. Therefore, when the speaker 1 drives the second linkage block 208 to move downward during vibration, the second linkage block 208 pushes the first linkage block 207 to move horizontally, so that the first linkage block 207 drives the air-permeable plate 206 to move horizontally and stretches the third spring 209. After the speaker 1 drives the second linkage block 208 to move upward, the third spring 209 rebounds to drive the air-permeable plate 206 to move back to its original position, so that the air-permeable plate 206 moves horizontally back and forth, thereby squeezing the air sandwich back and forth to discharge the hot air therein, avoiding heat accumulation in the air sandwich from interfering with the heat dissipation of the speaker 1.

[0035] When the speaker 1 stops playing music for storage, the operator needs to pull the first round rod 6 away from the connecting block 8 to unlock the speaker 1 and the square cover 4. During this process, at the moment when the first round rod 6 is pulled away from the connecting block 8, the speaker 1 and the universal wheels 2 lose their supporting force and fall to the ground, resulting in an impact. This is likely to damage the components inside the speaker 1 and the universal wheels 2, leading to a decrease in their service life. Therefore, a third linkage block 2012 is added below the speaker 1, as Figure 9 shown. Part of the inclined surface of the third linkage block 2012 is located inside the lower edge of the speaker 1. When the speaker 1 loses its supporting force and falls, its lower edge will contact the inclined surface of the third linkage block 2012 and push the third linkage block 2012 to move horizontally. The third linkage block 2012 drives the second round rod 2011 to move and compresses the fourth spring 2013. The second round rod 2011 drives the piston plate 2010 to move, so that the damping oil in the cavity 94 flows through the damping holes with a diameter of 1 mm on the piston plate 2010 to the other side of the piston plate 2010, thereby buffering the speaker 1 during the falling process and making the universal wheels 2 slowly fall to the ground, avoiding violent impacts that affect the service life. When the universal wheels 2 slowly fall to the ground, the side of the third linkage block 2012 away from the corresponding second round rod 2011 is flush with the outer surface of the speaker 1. Then, the operator pulls the square cover 4 and the parts on it upward, and the third linkage block 2012 moves upward along the outer surface of the speaker 1. It should be understood that the surface of the third linkage block 2012 is set as a smooth surface, and the fourth spring 2013 is set as a low-stiffness spring. When the square cover 4 moves up and down on the speaker 1, even if the fourth spring 2013 squeezes the third linkage block 2012 against the side of the speaker 1, only slight friction will be generated and it will not cause too much interference to the movement of the square cover 4.

[0036] Since the third linkage block 2012 is arranged below the speaker 1, a relatively large impact force is still generated when the speaker 1 falls onto the third linkage block 2012. If the third linkage block 2012 is initially arranged in contact with the lower side of the speaker 1, the vibration generated by the speaker 1 playing music will squeeze the third linkage block 2012. Due to the influence of the damping oil in the cavity 94 on the movement of the piston plate 2010, the resistance to the movement of the piston plate 2010 is large, resulting in the third linkage block 2012 being unable to move reciprocally at a high frequency along with the speaker 1, interfering with the shock absorption. Therefore, as Figure 10As shown in the figure, a fourth linkage block 2016 is added above the third linkage block 2012, and a notch for accommodating the fourth linkage block 2016 is formed in the third linkage block 2012. The vibration generated by the speaker 1 playing music pushes the fifth linkage block 2017 downward. The fifth linkage block 2017 pushes the fourth linkage block 2016 downward. The fourth linkage block 2016 drives the third round rod 2014 downward and compresses the fifth spring 2015. The resistance between the third linkage block 2012 and the third round rod 2014 is small, enabling the fourth linkage block 2016 to move back and forth at a high frequency along with the vibration of the speaker 1. When the first round rod 6 is pulled out of the connection block 8, the speaker 1 loses its supporting force and drops. At this time, the speaker 1 drives the fifth linkage block 2017 downward. The fifth linkage block 2017 drives the fourth linkage block 2016 downward. The fourth linkage block 2016 drives the third round rod 2014 downward. The third round rod 2014 stretches the fifth spring 2015. During this process, the fifth spring 2015 buffers the speaker 1 until the lower side of the fourth linkage block 2016 contacts the third linkage block 2012. At this time, the fourth linkage block 2016 cannot move downward any further, causing the fifth linkage block 2017 to push the fourth linkage block 2016 to move horizontally. The fourth linkage block 2016 pushes the third linkage block 2012 to move horizontally. As described above, the piston plate 2010 can buffer the speaker 1. That is, through the cooperation of the fifth spring 2015 and the second round rod 2011, two-stage buffering is provided for the speaker 1 during the falling process. The first half of the buffering effect is low but does not interfere with the damping effect of the speaker 1, and the second half of the buffering effect is strong, enabling the universal wheel 2 to slowly drop to the ground.

[0037] In summary: Through the cooperation of the ventilation plate 206, the first linkage block 207, the second linkage block 208, and the third spring 209, the hot air in the sandwich layer between the speaker 1 and the square cover 4 is discharged, preventing the hot air from accumulating in the sandwich layer and interfering with the heat dissipation of the speaker 1. Through the cooperation of the piston plate 2010, the second round rod 2011, the third linkage block 2012, the third round rod 2014, the fourth linkage block 2016, and the fifth linkage block 2017, two-stage buffering is provided for the speaker 1 during the falling process. The first half of the buffering effect is low but does not interfere with the damping effect of the speaker 1, and the second half of the buffering effect is strong, enabling the universal wheel 2 to slowly drop to the ground, avoiding violent impacts and affecting the service life of the internal components of the speaker 1 and the universal wheel 2.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes may be made therein without departing from the principles and spirit of the invention, and the scope of the invention is defined by the appended claims and their equivalents.
