[0002] A microphone, also known as a microphone, is an electroacoustic device and a microphone. It is a transducer for sound-to-electricity conversion. It generates voltage by acting on electroacoustic elements through sound waves, and then converts it into electrical energy. It is used in various sound amplification equipment. There are many types of microphones and the circuits are simple.

[0003] However, the broadcasting microphones currently on the market lack a corresponding convenient position adjustment mechanism, and when adjusting the distance of the microphone to the user's position, it is often necessary to adjust multiple sets of switch knobs, and only by adjusting the corresponding switches can it be adjusted in a specific direction.

[0004] However, in the actual adjustment process of the above-mentioned convenient position adjustment mechanism, the user is required to change his posture to a different posture when speaking to find the switch. The operation is not convenient enough and wastes the speaker's time. At the same time, it is also unable to adjust the microphone position corresponding to the random changes in the speaker's posture, and the adjustment experience is relatively poor. Summary of the invention

The snap-on arc block 80 is adapted to be snapped into the position of the arc groove 91, effectively preventing the wireless microphone 90 from falling off the snap-on arc block 80.

[0042] Specific use method of the utility model: During the use of the utility model, the wireless microphone 90 is connected to the control panel 10 by wireless. First, the C-shaped clamping block 20 can be removed from the control panel 10 by pulling the buckle 21 to disengage the clamping block 22 from the clamping slot 11, and then the wireless microphone 90 can be removed from the clamping arc block 80, so that the wireless microphone 90 can be carried for use;

[0043] When using the wireless microphone 90 on the workbench, the wireless microphone 90 can be installed on the card-connecting arc block 80, so that the arc groove 91 is card-connected on the card-connecting arc block 80, and the C-shaped clamping block 20 is card-connected on the control panel 10, so that the card block 22 is card-connected and installed in the card groove 11, and the upper rotating rod 41 can be rotated by squeezing and toggling the lever 43 with fingers, and the spline rod 45 penetrates into the spline groove 42 and is adapted to slide and connect with the upper rotating rod 41, so as to drive the lower rotating rod 44 to rotate synchronously, so that the pull rope three 72 is wound around the upper rotating rod 41, the pull rope two 62 is wound around the upper rotating rod 41, and the pull rope three 72 is wound around the lower rotating rod 44, so as to pull the meshing disk 1 50 away from the fixed ear 1 23. The one-side movement causes the meshing tooth 1 53 to be disengaged from the engagement with the clamping tooth 1 25, pulls the friction block 60 toward the side of the upper rotating rod 41 to disengage the friction block 60 from squeezing the lower hollow hinge rod 31, and moves the meshing plate 2 70 toward the side away from the fixed ear 2 81 to disengage the meshing tooth 2 73 on the meshing plate 2 70 from the engagement with the meshing tooth 3 83, so that the arc block 80 and the wireless microphone 90 can be rotated between the upper hollow hinge rod 34 at will, the lower hollow hinge rod 31 can slide and extend at will with the upper hollow hinge rod 34, and the telescopic rod 30 can be rotated at will with the fixed ear 1 23, so that the position between the wireless microphone 90 and the speaker can be adjusted at will;

[0044] After adjusting the position of the wireless microphone 90, release the lever 43, and under the elastic force of the thrust spring 55, the meshing plate 50 moves to one side of the fixed ear 23, and the meshing tooth 53 and the latching tooth 25 engage with each other, so that the telescopic rod 30 and the C-shaped clamping block 20 are locked. Under the elastic force of the thrust spring 61, the friction block 60 and the lower hollow hinged rod 31 are squeezed and fitted with each other, so that the upper hollow hinged rod 34 and the lower hollow hinged rod 31 are locked with each other and no longer move with each other, and the telescopic rod 30 no longer extends. Under the elastic force of the thrust spring 75, the meshing plate 70 is pushed to move, so that the meshing tooth 73 and the meshing tooth 83 on the meshing plate 70 engage with each other, and the arc block 80 and the upper hollow hinged rod 34 are relatively locked, thereby achieving the effect of fixing the wireless microphone 90 to the control panel 10.

[0045] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0046] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.
