Technical Field

[0001] The present invention relates to the field of sound amplification equipment, and in particular to a sound amplification device capable of reducing wind resistance. Background Art

[0002] Common mobile devices, such as drones, cars, and cruise ships, are often equipped with sound amplification devices that move with the device and diffuse the sound. To enhance the sound amplification effect, these devices typically include a housing with a speaker located within it. A protective net is attached to one end of the housing, with multiple evenly distributed sound-transmitting holes. Thus, the housing also protects the speaker.

[0003] In the related art, except for the sound outlet holes, the rest of the area on the shell of the sound amplification device is a closed area. When the device is moved, wind enters the shell through the sound outlet holes and is difficult to be discharged, which easily generates wind resistance and affects the normal flight of the drone.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The object of the present invention is to provide a sound amplification device with reduced wind resistance, so as to reduce wind resistance and reduce load energy consumption of mobile equipment.

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] refer to Figure 1-Figure 3 As shown, an embodiment of the present invention provides a sound amplification device for reducing wind resistance, comprising a housing 1 and a protective net 2 disposed at one end of the housing 1. The protective net 2 is provided with a plurality of sound outlet holes 21, and the housing 1 is provided with air vents 12 for dispersing wind. The arrangement of all sound outlet holes 21 is determined according to actual conditions; for example, all sound outlet holes 21 are evenly distributed on the protective net 2.

[0027] When using the wind resistance-reducing sound amplification device provided by the present invention, the device is mounted on a mobile device, such as a drone, and moves with the mobile device. During movement, wind enters the housing 1 through the sound outlet holes 21 on the protective net 2 and is then exhausted through the air vents 12. Expelling the wind that has entered the housing 1 reduces wind resistance and lowers the load energy consumption of the mobile device, thereby extending the effective operating time of the mobile device.

[0028] In some embodiments provided by the present invention, Figure 1-Figure 2 As shown, an exhaust slot 13 corresponding to the air vent 12 is opened on the outer wall of the shell 1, and the exhaust slot 13 is arranged in a shark gill shape.

[0029] The exhaust slots 13 are designed to be shark gill-shaped, and utilize the principles of fluid mechanics and bionics to optimize the fluid structure of the boundary layer of the surface of the sound reinforcement device, effectively reducing the frictional resistance of the wind and the resistance inside the shell 1, reducing the dependence on and influence of wind energy, achieving a better drag reduction effect, and obtaining a higher travel speed, further achieving the effect of reducing wind resistance and reducing the load energy consumption of mobile equipment.

[0030] Furthermore, if Figure 1-Figure 2As shown, the width of the shell 1 is set to gradually increase from one end to the other end, an opening 11 is provided at the wide end of the shell 1, and a protective net 2 for blocking the opening 11 is provided at the opening 11, and the outer wall of the shell 1 is provided with an inwardly recessed portion, the recessed portion forms an exhaust groove 13, and the recessed depth of the exhaust groove 13 gradually decreases from the end close to the protective net 2 to the end away from the protective net 2, so as to be in the shape of a shark gill, and the air vents 12 are opened on the side wall of the exhaust groove 13 close to the protective net 2.

[0031] Furthermore, the number of the air vents 12 is set to be multiple. The specific number of the air vents 12 is determined according to actual needs. Figure 1 and Figure 2 There are two middle air holes 12 . The number of exhaust slots 13 is equal to the number of air holes 12 , and the two correspond one to one, with one air hole 12 being connected to one exhaust slot 13 .

[0032] Furthermore, if Figure 1-Figure 2 As shown, the air vents 12 are set as waist-shaped holes parallel to the width direction of the housing 1. It should be noted that the air vents 12 are not limited to being set parallel to the width direction of the housing 1, nor are they limited to being waist-shaped holes. This is just an example.

[0033] Furthermore, if Figure 1 As shown, a guide groove 14 is provided on the bottom wall of one end of the exhaust slot 13 close to the air vent 12 .

[0034] During specific use, the wind is discharged from the air vent 12 and guided by the guide groove 14 into the exhaust groove 13, and moves along the length direction of the exhaust groove 13. During the movement of the wind, the shape of the exhaust groove 13 allows the wind to gradually diffuse and be discharged into the atmosphere, reducing the possibility of the wind squeezing the side wall of the shell 1 during movement.

[0035] In some embodiments provided herein, a detachable member (not shown) is provided between the protective net 2 and the housing 1 at one end near the protective net 2 for connecting the two. The protective net 2 is detachably connected to the housing 1 via the detachable member, facilitating inspection of the protective net 2 and the interior of the housing 1.

[0036] Furthermore, the detachable parts are bolts, and the protective net 2 is connected to the shell 1 via the bolts.

[0037] Furthermore, both ends of the protective net 2 in the vertical direction are bent toward the side close to the housing 1 , thereby forming an inclined surface.

[0038] During maintenance, the bolts can be tightened and removed. At this time, the protective net 2 is moved away from the shell 1 until the protective net 2 is removed, which is convenient for maintenance of the inside of the shell 1 and the protective net 2. After the maintenance is completed, the protective net 2 is moved toward the shell 1 until the side of the protective net 2 close to the shell 1 is in contact with the end of the shell 1 close to the protective net 2. The bolts are turned until the protective net 2 and the shell 1 are fixed to complete the maintenance.

[0039] In some embodiments provided by the present invention, Figure 3 As shown, a sound-transmitting dustproof net 3 for blocking dust is provided on one side of the protective net 2 close to the housing 1 .

[0040] During specific use, when dust enters the shell 1 through the sound outlet 21 on the protective net 2 with the wind, the sound-transparent dustproof net 3 can prevent the dust from continuing to move in the shell 1, thereby reducing the possibility of dust adhering to the inner wall of the shell 1 without affecting the sound reinforcement effect.

[0041] Furthermore, the sound-permeable dust-proof net 3 is set to be made of acoustic sponge material. It should be noted that the material of the sound-permeable dust-proof net 3 is not limited to acoustic sponge, and can also be other materials. This is also an example.

[0042] This specification uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
