[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0024] The following describes an embodiment of the utility model based on its overall structure.

[0025] A versatile vehicle microphone, such as Figures 1 to 5 As shown, it includes a receiving column 100, a microphone tube 130 is arranged on the top of the receiving column 100, a mesh cover 140 is connected to the top of the microphone tube 130, a microphone tube 130 is arranged at the bottom end of the microphone tube 130 and the top end of the receiving column 100, a positioning component 150 is fixed to the bottom end of the receiving column 100, a lower tube 110 is sleeved on the outer wall of the positioning component 150, and an upper tube 120 is sleeved on the outer wall of the receiving column 100;

[0026] The positioning assembly 150 includes a bottom column 158, the top of the bottom column 158 is provided with two sets of connecting rods 151 fixed to the bottom end of the receiving column 100, a piston cylinder 153 is fixed in the bottom column 158, the bottom end of the bottom column 158 is provided with a suction cup 152 connected to the bottom end of the piston cylinder 153, a piston 154 is slidably provided in the piston cylinder 153, and the top end of the piston 154 is provided with a threaded rod 155 extending to the top end of the bottom column 158;

[0027] The outer wall of the threaded rod 155 is sleeved with a threaded tube 156 , and the outer wall of the threaded tube 156 is fixedly connected to the bottom column 158 . The top of the threaded rod 155 is located between the two groups of connecting rods 151 and is provided with a handle 157 .

[0028] like Figure 1 As shown, the user can directly hold the first L-arm 111 and the second L-arm 121 between the lower tube 110 and the upper tube 120 to use the microphone, and the gap between them can increase the friction between the palm of the hand, so that the user can better grasp the microphone;

[0029] When the microphone needs to be fixed in the car, an upward external force is applied to the lower tube 110 until the top of the first L-arm 111 contacts the bottom of the upper tube 120. At this time, the bottom of the lower tube 110 is flush with the bottom of the receiving column 100, and then the suction cup 152 contacts the glass or smooth surface of the car. Then, the handle 157 is turned to drive the threaded rod 155 to rotate, and with the cooperation of the threaded tube 156, it rises upward, and at the same time drives the piston 154 at the end to slide upward in the piston tube 153, so that the piston 154 The space below is in a negative pressure state, so the suction cup 152 can be firmly fixed on the surface of the glass inside the car, thereby fixing the microphone. Then, the lower tube 110 is pulled to slide along the outer wall of the supporting column 100 to recover. At the same time, an external force away from the microphone tube 130 is applied to the upper tube 120, so that the bottom end of the second L arm 121 contacts the lower tube 110, so that the ball shaft 131 is exposed outside, and the microphone tube 130 can be pushed to rotate to the required angle based on the ball shaft 131, thereby further expanding the flexibility of the microphone.

[0030] Please refer to Figure 1 and Figure 4 A plurality of first L-arms 111 are fixed to the top of the lower tube 110, and a first positioning rod 112 fixed to the top of the lower tube 110 is provided on one side of each first L-arm 111, and a first blind hole is provided on the top of the first L-arm 111.

When the two need to be relatively close, an upward external force is applied to the lower tube 110. At this time, the first positioning rod 112 slides up along the second blind hole until the top of the multiple groups of first L arms 111 contact the bottom end of the upper tube 120, so that the positioning component 150 can be operated to be adsorbed on the glass or smooth surface of the car. Conversely, a downward external force is applied to the upper tube 120 to adjust the angle of the microphone tube 130.

[0032] Please refer to Figure 2 and Figure 5 The inner wall of each set of first L-arms 111 is provided with a restraining block extending into the receiving column 100, and a travel groove is provided at the contact position between the outer wall of the receiving column 100 and the restraining block.

[0033] The purpose of utilizing the restraining block to slide only in the travel groove is to restrain the lower cylinder 110 and the upper cylinder 120 to prevent them from falling from the outer wall of the receiving column 100 .

[0034] Please refer to Figure 2 A ball shaft groove is provided at the contact position between the top end of the receiving column 100 and the ball shaft 131, and a rubber layer is embedded in the ball shaft groove.

[0035] By using the ball shaft 131 groove in conjunction with the ball shaft, the microphone tube 130 can be rotated over a wide angle range to meet a variety of needs. At the same time, the rubber layer can stabilize the microphone tube 130 after rotating to a specified angle, ensuring that it can be used normally by humans.

[0036] Please refer to Figure 1 The top end of the microphone tube 130 is threadedly connected to the inner wall of the mesh cover 140, and the curved inner wall of the mesh cover 140 is provided with noise reduction cotton.

[0037] The mesh cover 140 can be disassembled and cleaned, or the components inside the microphone tube 130 can be replaced. At the same time, the noise reduction cotton can be used to reduce the surrounding noise, so that it can better receive the sound transmitted from the front.

[0042] When the microphone needs to be fixed in the car, an upward external force is applied to the lower tube 110 until the top of the first L-arm 111 contacts the bottom of the upper tube 120. At this time, the bottom of the lower tube 110 is flush with the bottom of the receiving column 100, and then the suction cup 152 contacts the glass or smooth surface of the car. Then, the handle 157 is turned to drive the threaded rod 155 to rotate, and with the cooperation of the threaded tube 156, it rises upward, and at the same time drives the piston 154 at the end to slide upward in the piston tube 153, so that the piston 154 The space below is in a negative pressure state, so the suction cup 152 can be firmly fixed on the surface of the glass inside the car, thereby fixing the microphone. Then, the lower tube 110 is pulled to slide along the outer wall of the supporting column 100 to recover. At the same time, an external force away from the microphone tube 130 is applied to the upper tube 120, so that the bottom end of the second L arm 121 contacts the lower tube 110, so that the ball shaft 131 is exposed outside, and the microphone tube 130 can be pushed to rotate to the required angle based on the ball shaft 131, thereby further expanding the flexibility of the microphone.

[0043] Please refer to Figure 1 and Figure 4 A plurality of first L-arms 111 are fixed to the top of the lower tube 110, and a first positioning rod 112 fixed to the top of the lower tube 110 is provided on one side of each first L-arm 111, and a first blind hole is provided on the top of the first L-arm 111.

[0044] The lower tube 110, the upper tube 120 and the L arm are all made of rubber, which can increase the friction between the receiving column 100 and the outer wall of the positioning component 150 so that it will not slide easily. When the two need to be relatively close, an upward external force is applied to the lower tube 110. At this time, the first positioning rod 112 slides up along the second blind hole until the top of the multiple groups of first L arms 111 contact the bottom end of the upper tube 120, so that the positioning component 150 can be operated to be adsorbed on the glass or smooth surface of the car. Conversely, a downward external force is applied to the upper tube 120 to adjust the angle of the microphone tube 130.

[0045] Please refer to Figure 2 and Figure 5The inner wall of each set of first L-arms 111 is provided with a restraining block extending into the receiving column 100, and a travel groove is provided at the contact position between the outer wall of the receiving column 100 and the restraining block.

[0048] By using the ball shaft 131 groove in conjunction with the ball shaft, the microphone tube 130 can be rotated over a wide angle range to meet a variety of needs. At the same time, the rubber layer can stabilize the microphone tube 130 after rotating to a specified angle, ensuring that it can be used normally by humans.
