Description

Technical Field

[0001] This invention belongs to the field of wireless microphone technology, and specifically relates to a drop-proof wireless microphone. Background Technology

[0002] Microphones are essential sound pickup devices for people to sing karaoke, give speeches, and host meetings. They are widely used in places such as KTVs, classrooms, and conference halls. To make it easier for people to move around while holding the microphone, most existing microphones are wireless.

[0003] Microphones can move around with the user during use, and they may fall during this process, which can easily damage them. For some expensive microphones, damage means significant economic loss and can also affect work. Summary of the Invention

[0004] The purpose of this invention is to provide a drop-proof wireless microphone in order to solve the problems mentioned in the background art.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] A drop-proof wireless microphone includes a microphone body, which includes a head and a cylindrical body. The cylindrical body has a sleeve and an internal groove with a return spring. The inner wall of the sleeve has a pressure plate that drives the return spring to extend and retract and is connected to the return spring. The head has two symmetrically distributed pivots on both sides of the head and located on the same straight line. A coil spring that drives the pivots to return is provided between the pivots and the head. A protective mechanism that can rotate around the pivots is provided between the two pivots. A connecting rope for driving the pivots to rotate is provided between the two pivots and the sleeve.

[0007] Preferably, the protective mechanism includes a first protective frame fixed to the head and two or more second protective frames provided on the rotating shaft, and a limiting rope for controlling the distance is provided between the first and second protective frames.

[0008] Preferably, the sleeve has two or more guide rods along its circumference on the side away from the head, and the cylinder has two or more guide rails corresponding to the guide rods one by one. The guide rails are provided with protective strips that protect the cylinder and are connected to the guide rods.

[0009] Preferably, the guide rail is J-shaped.

[0010] Preferably, the protective strip is made of rubber material.

[0011] Preferably, the protective strip is divided into an exposed part and an internal part, the internal part comprising two or more individual units that are movably connected to form a strip, with gaps between adjacent individual units.

[0012] Preferably, the built-in groove is provided with a first telescopic rod, and the first and second protective frames are each provided with an airbag on the side away from the head, which communicates with the inner cavity of the first telescopic rod for protecting the head.

[0013] The beneficial effects of this invention are as follows:

[0014] This invention features a rotatable protective mechanism and a retractable protective strip on the microphone. The protective mechanism and strip automatically open when the microphone is dropped, providing comprehensive protection for the microphone. It has a fast response time, a simple structure, and effectively improves the safety of microphone use. Attached Figure Description

[0021] The present application will now be described in further detail. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example 1

[0023] like Figure 1-5As shown, a drop-proof wireless microphone includes a microphone body, which includes a head 1 and a cylindrical body 2. The cylindrical body 2 is provided with a sleeve 3 and an internal groove. A return spring 4 is provided in the internal groove. A pressure plate 5 is provided on the inner side wall of the sleeve 3 to drive the return spring 4 to extend and retract and is connected to the return spring 4. The head 1 is provided with two symmetrically distributed rotating shafts 6 on both sides of the head 1 and located on the same straight line. A coil spring is provided between the rotating shafts 6 and the head 1 to drive the rotating shafts 6 to return. A protective mechanism that can rotate around the rotating shafts 6 is provided between the two rotating shafts 6. A connecting rope 7 for driving the rotating shafts 6 to rotate is provided between the two rotating shafts 6 and the sleeve 3.

[0024] As a further embodiment of the present invention, the protective mechanism includes a first protective frame 8 fixed on the head 1 and two or more second protective frames 9 provided on the rotating shaft 6, and a limiting rope 10 for controlling the distance is provided between the first protective frame 8 and the second protective frames 9.

[0025] In the above embodiment, the user picks up the sleeve 3 on the wireless microphone. Under the action of gravity, the microphone body 2 moves downward, causing the sleeve 3 to move upward relative to the body 2. At this time, the pressure plate 5 compresses the return spring 4. Simultaneously, the connecting rope 7 between the rotating shaft 6 and the sleeve 3 is in a relaxed state. The coil spring automatically returns to its original state after the connecting rope 7 is relaxed, causing the rotating shaft 6 to rotate. When the rotating shaft 6 rotates, it drives the protective mechanism to fold, exposing the head 1 of the wireless microphone. At this time, the wireless microphone is in normal use.

[0026] When the wireless microphone falls downwards, both sleeve 3 and cylinder 2 are in a state of weightlessness. At this time, under the action of the return spring 4, sleeve 3 returns to its initial position relative to cylinder 2, and at the same time, the connecting rope 7 is tightened. The tightening of the connecting rope 7 causes the coil spring to tighten again, causing the rotating shaft 6 to rotate, which in turn causes the protective mechanism to open and protect the head 1. When the wireless microphone falls to the ground, the protective mechanism contacts the ground, thus providing full protection for the wireless microphone.

[0027] When the protective mechanism is deployed, its primary protective frame 8 is fixed, and the device drives two or more secondary protective frames 9 to rotate. During the rotation of the secondary protective frames 9, the limiting rope 10 ensures that the secondary protective frames 9 maintain the same distance and angle from the primary protective frame 8 and between adjacent secondary protective frames 9, preventing the head 1 from contacting the ground. The maximum deployment angle of the secondary protective frames 9 is determined by the tension of the coil spring.

[0028] As a further embodiment of the present invention, the sleeve 3 is provided with two or more guide rods 11 along its circumference on the side away from the head 1, and the cylinder 2 is provided with two or more guide rails 12 corresponding to the guide rods 11 one by one. The guide rails 12 are provided with protective strips that protect the cylinder 2 and are connected to the guide rods 11.

[0029] In the above embodiment, when the sleeve 3 moves away from the head 1, it drives the guide rod 11 to move within the guide rail 12, causing the protective strip within the guide rail 12 to move synchronously. The protective strip is partially moved out of the guide rail 12, at which point the protective strip forms multiple tentacles at the end of the cylinder 2 away from the head 1 (i.e., the tail of the cylinder 2). During the fall of the wireless microphone, the tentacles first contact the ground, thereby protecting the cylinder 2 of the wireless microphone as well.

[0030] As a further embodiment of the present invention, the guide rail 12 is J-shaped.

[0031] As a further embodiment of the present invention, the protective strip is made of rubber material.

[0032] As a further embodiment of the present invention, the protective strip is divided into an exposed portion 13 and an internal portion 14. The internal portion 14 includes two or more individual units that are movably connected to form a strip shape, with gaps between adjacent individual units.

[0033] In the above embodiment, the J-shaped guide rail 12 can keep the cylinder 2 with a small volume after the protective strip is retracted, avoiding the inconvenience of using the wireless microphone due to the guide rail 12 extending too far.

[0034] The protective strip is made of rubber, which provides a certain buffer when it comes into contact with the ground. The protective strip can move freely within the J-shaped guide rail 12 without getting stuck.

[0035] The protective strip is designed as a multi-segment structure at the end near the guide rod 11, allowing the inner part 14 of the protective strip to move normally at the tail of the J-shaped guide rail 12. If the protective strip were a single piece, there would be significant friction between the protective strip and the guide rail 12 when the strip bends within the guide rail 12, thus affecting the normal movement of the sleeve 3. The multi-segment protective strip not only facilitates bending and deformation but also serves to longitudinally connect the guide rod 11 and the exposed part 13.

[0036] As a further embodiment of the present invention, a first telescopic rod 15 is provided in the built-in groove, and an airbag 16 for protecting the head 1 is provided on the side of the first protective frame 8 and the second protective frame 9 away from the head 1, which communicates with the inner cavity of the first telescopic rod 15.

[0037] In the above embodiment, the pressure plate 5 compresses the first telescopic rod 15 during its movement, causing the gas inside the first telescopic rod 15 to enter the airbag 16, thereby causing the airbag 16 to inflate. The inflated airbag 16 improves the protective effect of the protective mechanism on the head 1, and provides a certain degree of cushioning when the protective mechanism comes into contact with the ground.

[0038] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
