Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 and Figure 7 This utility model provides a technical solution: a vibration motor with auxiliary noise reduction, including a hollow base 1, a vibration motor body 2, a heat dissipation mechanism 3, and a noise reduction mechanism 4; the upper surface of the hollow base 1 is connected to the vibration motor body 2, the surface of the vibration motor body 2 is provided with the heat dissipation mechanism 3, and the outer side of the vibration motor body 2 is provided with the noise reduction mechanism 4; the noise reduction mechanism 4 includes a protective cover 401, a vacuum layer 402, a sound insulation plate 403, sound-absorbing cotton 404, a socket 405, a through groove 406, an L-shaped insert 407, a bidirectional threaded rod 408, a worm gear 409, a handle 410, and a worm 411; the upper surface of the hollow base 1 abuts against the protective cover 401, the interior of the protective cover 401 is provided with a vacuum layer 402, and the protective cover 401... A sound insulation plate 403 is connected to the inner wall of the hollow seat 1. A sound-absorbing cotton 404 is connected to the inner wall of the sound insulation plate 403. Insertion holes 405 are provided on the front, back and rear parts of the inner walls of the sound insulation plate 403 and the sound-absorbing cotton 404. A through groove 406 is provided on the upper surface of the hollow seat 1. An L-shaped insert rod 407 is slidably connected in the through groove 406. The L-shaped insert rod 407 is engaged in the insertion hole 405. A double-threaded rod 408 is threadedly connected to the L-shaped insert rod 407. A worm gear 409 is connected to the outer side of the double-threaded rod 408. The double-threaded rod 408 is rotatably connected to the inner wall of the hollow seat 1. A rotating handle 410 is rotatably passed through the inner wall of the hollow seat 1. A worm 411 is connected to the outer side of the rotating handle 410. The worm 411 is meshed with the bottom of the worm gear 409.

[0029] In practice, the protective cover 401 is placed on the vibratory motor body 2 and abuts against the hollow seat 1. Then, the handle 410 is rotated to drive the worm gear 411 to drive the worm wheel 409 to rotate, thereby driving the bidirectional threaded rod 408 to rotate in the L-shaped insert 407, which in turn drives the L-shaped insert 407 to slide in the through groove 406. The L-shaped insert 407 is inserted into the insertion hole 405, and the protective cover 401 is fixed on the outside of the vibratory motor body 2. The sound-absorbing cotton 404 absorbs the noise generated by the vibratory motor body 2, and the sound insulation plate 403 and the vacuum layer 402 block the noise generated by the vibratory motor body 2, thereby giving this utility model a noise reduction function.

[0030] See Figure 1 , Figure 2 and Figure 6 It is known that the heat dissipation mechanism 3 includes a heat-absorbing copper pipe 301, a return hose 302, a return rigid pipe 303, an air cooler 304, a delivery hose 305, a circulation pump 306, and a delivery rigid pipe 307. The surface of the vibration motor body 2 is wrapped with a heat-absorbing copper pipe 301. One end of the heat-absorbing copper pipe 301 is connected to the return hose 302. The return hose 302 penetrates the inner wall of the protective cover 401, the sound insulation plate 403, and the sound-absorbing cotton 404 and is connected to the return rigid pipe 303. The other end of the return rigid pipe 303 is connected to the air cooler. The air cooler 304 is connected to the upper surface of the hollow base 1. The end of the heat-absorbing copper tube 301 away from the return hose 302 is connected to the delivery hose 305.

The circulation pump 306 is connected to the upper surface of the hollow base 1. The end of the circulation pump 306 away from the delivery hose 305 is connected to the delivery rigid pipe 307. The delivery rigid pipe 307 is connected to the bottom of the air cooler 304.

[0031] In practice, the coolant in the heat-absorbing copper pipe 301 absorbs the heat generated by the vibration motor body 2, and then is sent from the delivery hose 305 to the air cooler 304 by the circulation pump 306 through the delivery hard pipe 307. After the coolant is cooled by the air cooler 304, it returns to the heat-absorbing copper pipe 301 through the return hard pipe 303 and the return hose 302, and absorbs the heat generated by the vibration motor body 2 again, circulating continuously, so that the present invention has the function of heat dissipation.

[0032] In summary: When using this utility model, firstly, it is installed on the device requiring vibration. The motor inside the vibration motor body 2 drives the eccentric blocks on both sides to rotate, generating vibration through inertia, thus causing the device to vibrate. The pores of the sound-absorbing cotton 404 absorb the sound waves generated by the operation of the vibration motor body 2, reducing the reflection and propagation of sound waves in space. The sound insulation plate 403 and the vacuum layer 402 isolate the noise generated by the operation of the vibration motor body 2. The coolant in the heat-absorbing copper pipe 301 absorbs the heat generated by the vibration motor body 2, and is then sent to the air cooler 304 by the circulating pump 306 for heat dissipation. It then returns to the heat-absorbing copper pipe 301 to absorb the heat generated by the vibration motor body 2 again, continuously circulating to continuously cool the vibration motor body 2.
