Description

Technical Field

[0001] This utility model belongs to the field of microphone technology, specifically relating to a boom-type microphone. Background Technology

[0002] A boom microphone is a device that extends the microphone to the vicinity of the target sound source using a telescopic or fixed-length boom. It is commonly used in film and television recording, stage performances, or interviews. Its core structure includes a lightweight boom, an adjustable microphone stand, and a shock-absorbing device, which can accurately capture sound without interfering with the picture. Some high-end models are equipped with a folding design, motorized pan-tilt head, or vibration-isolated suspension to improve portability and sound recording stability.

[0003] Chinese patent CN220440884U discloses a detachable microphone, including a mounting plate with two pairs of symmetrical mounting holes at its top. A U-shaped plate is fixedly connected to the top of the mounting plate, and a bidirectional screw is rotatably connected between the inner sides of the U-shaped plate. A pair of symmetrical nut blocks are threaded onto the surface of the bidirectional screw. One side of one nut block is rotatably connected to a first connecting rod, and the other side of the nut block is rotatably connected to a second connecting rod. This patent, by setting up a motor, bidirectional screw, nut blocks, first connecting rod, and second connecting rod, allows the motor to drive the bidirectional screw to rotate, causing the nut blocks to drive the first and second connecting rods to move and cooperate with each other, moving the microphone body down from the ceiling. This eliminates the need for workers to climb to the ceiling with a ladder to repair or replace the microphone body, avoiding the risk of workers falling from ladders and being injured.

[0004] However, the current device has the following problems: the linkage frame in the device lacks a limiting frame, and it bends due to insufficient lateral force when it is stretched and lowered, which causes the microphone to be unable to descend vertically, affecting the pickup accuracy and even damaging the internal wires or joint components. Therefore, we propose a boom-type microphone. Utility Model Content

[0005] The purpose of this invention is to provide a boom-type microphone that can solve the problem in related technologies where the connecting rod frame lacks a limiting frame, causing it to bend due to insufficient lateral force during descent, resulting in the microphone being unable to descend vertically, affecting pickup accuracy, and even damaging internal wiring or joint components.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A boom-type microphone includes a mounting plate. A U-shaped plate is fixedly connected to the bottom of the mounting plate. A bidirectional screw is rotatably connected to the inner wall of the U-shaped plate. Nut blocks are threaded onto the threaded surfaces of the bidirectional screw with opposite thread directions. A connecting rod is rotatably connected to both sides of the two nut blocks. Anti-bending devices are provided on both sides of the U-shaped plate to prevent the connecting rod from bending. The anti-bending devices include two top plates, the sides of which are fixedly connected to the sides of the U-shaped plate. Vertical rods are fixedly connected to the bottom of the two top plates. Connecting plates are fixedly connected to both sides of a movable plate. Base plates are fixedly connected to the bottom of the two vertical rods. Long springs are provided between the bottom of the two top plates and the tops of the two connecting plates. Two handles are fixedly connected to both sides of the movable plate.

[0008] Preferably, each of the two linkage frames has two sliders rotatably connected to its side, and the bottom of each of the sliders is slidably connected to the same movable plate, with a microphone fixedly connected to the bottom of the movable plate.

[0009] Preferably, the tops of both nut blocks are in contact with the inner wall of the U-shaped plate, and the inner walls of the two connecting plates are slidably connected to the circumferential surfaces of the two vertical rods.

[0010] Preferably, the two base plates are located below the two connecting plates, and a gap is left between the circumferential surfaces of the two long springs and the circumferential surfaces of the two vertical rods.

[0011] Preferably, the top plate is provided with a segmented adjustment device on its side. The segmented device includes two long plates, the sides of which are fixedly connected to the sides of the two top plates. Each side of the two long plates is fixedly connected to a plurality of protrusions II. Each side of the two connecting plates is fixedly connected to a circular plate. Each side of the two circular plates is fixedly connected to a fixing rod. One end of each fixing rod slides through a moving rod. The end of each moving rod away from the fixing rod is fixedly connected to a protrusion I. A short spring is provided between the sides of the two circular plates and the sides of the two protrusions I.

[0012] Preferably, the circular surfaces of the plurality of second protrusions are located on the movement trajectory of the circular surfaces of the two first protrusions, and the side surfaces of the two long plates are located on the movement trajectory of the circular surfaces of the two first protrusions.

[0013] Preferably, the circular surfaces of the plurality of second protrusions are provided with smooth surfaces, and the circular surfaces of the two first protrusions are provided with smooth surfaces.

[0014] The technical effects achieved by this utility model are as follows:

[0015] This invention, through the setting of an anti-bending device, ensures the coordination of the top plate, vertical rod, connecting plate, bottom plate, long spring, and handle. The handle, which assists in two-handed gripping, distributes the force. The connecting plate moves on the circumferential surface of the vertical rod, the bottom plate restricts the movement range of the connecting plate, the movement of the connecting plate stretches the spring, and the vertical rod restricts the connecting plate. This ensures that the microphone descends vertically and stably, avoiding deviation or bending, improving the accuracy of sound pickup, reducing structural wear, extending service life, and enhancing operational safety and reliability.

[0016] This utility model, through the setting of a segmented device, enables the cooperation of a long plate, a second protrusion, a circular plate, a fixed rod, a moving rod, a first protrusion, and a short spring. The movement of the moving rod drives the movement of the first protrusion. When the first protrusion moves to the position of the second protrusion, the circular surface of the second protrusion pushes the circular surface of the first protrusion, which in turn drives the moving rod to move. When the circular surface of the second protrusion no longer pushes the first protrusion, the first protrusion resets and moves under the elastic force of the corresponding short spring. The second protrusion restricts the movement position of the first protrusion, thus realizing segmented adjustment. Attached Figure Description

[0025] like Figures 1-3 As shown, a boom-type microphone includes a mounting plate 1. A U-shaped plate 2 is fixedly connected to the bottom of the mounting plate 1.

Anti-bending devices 8 are provided on both sides of the U-shaped plate 2 to prevent the connecting rod frame 5 from bending. The anti-bending device 8 includes two top plates 81. The sides of the two top plates 81 are fixedly connected to both sides of the U-shaped plate 2. Vertical rods 82 are fixedly connected to the bottom of the two top plates 81. Connecting plates 83 are fixedly connected to both sides of the movable plate 7. A base plate 84 is fixedly connected to the bottom of the two vertical rods 82. A long spring is provided between the bottom of the two top plates 81 and the top of the two connecting plates 83. Spring 85, two handles 86 are fixedly connected to both sides of the movable plate 7, two sliders 6 are rotatably connected to the sides of the two connecting rod frames 5, the bottom of multiple sliders 6 are slidably connected to the same movable plate 7, the bottom of the movable plate 7 is fixedly connected to the microphone 10, when the microphone 10 is needed, the operator pulls the movable plate 7 downward, the movement of the movable plate 7 causes the sliders 6 to move towards the middle, causing the connecting rod frame 5 to rotate from a contracted state and slowly unfold, thereby realizing the microphone 10 moving downward, the top of the two nut blocks 4 are in contact with the inner wall of the U-shaped plate 2, the inner walls of the two connecting plates 83 are slidably connected to the circumferential surface of the two vertical rods 82, the two bottom plates 84 are located below the two connecting plates 83, and there is a gap between the circumferential surface of the two long springs 85 and the circumferential surface of the two vertical rods 82;

[0026] Based on the above structure, the grip 86, which is used for hand-held assistance, distributes the force. The movement of the moving plate 7 drives the movement of the connecting plate 83. The connecting plate 83 moves on the circumferential surface of the vertical rod 82. The base plate 84 limits the range of movement of the connecting plate 83. The movement of the connecting plate 83 stretches the spring 85. The vertical rod 82 limits the connecting plate 83, which can ensure that the microphone 10 descends vertically and stably, avoids deviation or bending, improves the accuracy of sound pickup, reduces structural wear, extends service life, and improves operational safety and reliability.

[0027] like Figures 4-5As shown, a segmented adjustment device 9 is provided on the side of the top plate 81. The segmented device 9 includes two long plates 91, the sides of which are fixedly connected to the sides of the two top plates 81. Multiple protrusions 92 are fixedly connected to the sides of the two long plates 91. Circular plates 93 are fixedly connected to the sides of the two connecting plates 83. Fixed rods 94 are fixedly connected to the sides of the two circular plates 93. One end of each fixed rod 94 slides through a moving rod 95.

Short springs 97 are provided between the sides of the two circular plates 93 and the sides of the two protrusions 96. The circular surfaces of the multiple protrusions 92 are located on the movement trajectory of the circular surfaces of the two protrusions 96. The sides of the two long plates 91 are located on the movement trajectory of the circular surfaces of the two protrusions 96. The circular surfaces of the multiple protrusions 92 and the circular surfaces of the two protrusions 96 are provided with smooth surfaces.

[0028] According to the above structure, the movement of the connecting plate 83 drives the movement of the circular plate 93, the movement of the circular plate 93 drives the movement of the fixed rod 94, the movement of the fixed rod 94 drives the movement of the moving rod 95, and the movement of the moving rod 95 drives the movement of the first protrusion 96. When the first protrusion 96 moves to the position of the second protrusion 92, the circular surface of the second protrusion 92 pushes the circular surface of the first protrusion 96, which drives the moving rod 95 to move. When the circular surface of the second protrusion 92 no longer pushes the first protrusion 96, the first protrusion 96 resets and moves under the elastic force of the corresponding short spring 97. The second protrusion 92 restricts the movement position of the first protrusion 96, realizing segmented adjustment.
