Description

Technical Field

[0002] Among various types of microphones, there is a type of microphone called a lavalier microphone, which can be clamped on an object (for example, the object can be a collar of clothing) to pick up sound. The lavalier microphone may include a magnetic body and a magnetic member. The lavalier microphone can be fixed by clamping the object between the magnetic body and the magnetic member. However, due to the small size of the lavalier microphone, the size of the magnetic member used cannot be too large, resulting in insufficient suction force of the magnetic body and the magnetic member, and thus insufficient friction force generated by the magnetic body and the magnetic member on the object, making it easy to fall off the object. Therefore, the existing lavalier microphone has the problem of being easy to fall off from the object. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0038] Please also refer to Figure 1 and Figure 2In one embodiment, a clamping device is provided, which is used to fix the microphone 11 to the clamped object 2, and includes a first magnetic component 3 and a second magnetic component 4. The first magnetic component 3 includes a first plate 30, a recess 300 and a first magnet 31. There are at least two groups of recesses 300, and at least two groups of recesses 300 are opened and placed in the first plate 30. The first magnet 31 is arranged on the first plate 30, and the microphone 1 is arranged on the first magnetic component 3, and the first magnet 31 is located on the section of the first plate 30 between the at least two groups of recesses 300. The clamped object 2 can be clamped between the first magnetic component 3 and the second magnetic component 4, and the second magnetic component 4 includes a second plate 40, a protrusion 400 and a second magnet 41. The convex part 400 can be embedded in the concave part 300, and the clamped object 2 is clamped between the convex part 400 and the concave part 300. The convex part 400 is at least two groups, and the second plate body 40 is opened between the at least two groups of convex parts 400, and the convex parts 400 and the concave parts 300 are arranged one by one. The second magnet 41 is arranged on the second plate body 40, and the second magnet 41 is located on the second plate body 40 between the at least two groups of convex parts 400, and the second magnet 41 can attract the first magnet 31.

[0039] For the convenience of explanation, a rectangular coordinate system O-XYZ is established in each figure. The Z axis of the rectangular coordinate system is parallel to the length direction of the first magnetic component 3 and the second magnetic component 4. The X axis and the Y axis of the rectangular coordinate system are parallel to the radial direction of the first magnetic component 3 and the second magnetic component 4. The positive direction of the X axis, the Y axis or the Z axis remains the same in each figure. The microphone 1 can be an electret microphone unit. The specific structure of the first magnetic component 3 and the second magnetic component 4 can refer to the subsequent content of the embodiment. The protrusion 400 can be a cylindrical protrusion, and the recess 300 can be a cylindrical groove. The diameter of the protrusion 400 and the diameter of the recess 300 can be substantially the same. The microphone 1 can be bonded to the first magnetic component 3. The microphone 1 can also be set on a circuit board, and then the circuit board is fixed to the first magnetic component 3 with screws.

[0040] Please also refer to Figure 1 and Figure 2, the first magnetic component 3 and the second magnetic component 4 can be clamped on the clamped object 2 (for example, the clamped object 2 can be the collar of a piece of clothing). When in use, the clamped object 2 is clamped between the first magnetic component 3 and the second magnetic component 4, and the magnetic force between the first magnetic component 3 and the second magnetic component 4 can generate friction on the clamped object 2. Since the clamped object 2 can be clamped between the first magnetic component 3 and the second magnetic component 4, and the clamped object 2 can be clamped between the convex portion 400 and the concave portion 300. Therefore, when the first magnetic component 3 is fixed to the clamped object 2, the convex portion 400 can press against the clamped object 2 on the concave portion 300, thereby increasing the friction between the first magnetic component 3 and the second magnetic component 4 and the clamped object 2, so that the first magnetic component 3 fixed with the microphone 1 is not easy to fall off from the clamped object 2. Since the microphone 1 is fixed on the first magnetic component 3, the microphone 1 is also not easy to fall off from the clamped object 2.

[0041] Please also refer to Figure 1 and Figure 3 Optionally, the first magnet 31 may be a magnet. The first magnet 31 may be fixed to the inner side of the first plate 30 by bonding.

For example, the central axes of the three recesses 300 in each group of recesses 300 may be parallel to each other and coplanar. The arrangement directions of the two groups of recesses 300 may be parallel to each other. The more the number of recesses 300 is, the better the effect of increasing the friction between the first magnetic component 3 and the second magnetic component 4 on the clamped object 2 is.

[0045] like Figure 3 As shown, if there are multiple groups of recesses 300, the two first magnets 31 can be located in the section between the two groups of recesses 300 with the smallest distance on the first plate 30. If the two first magnets 31 are located in the section between at least two groups of recesses 300 on the first plate 30, the moments of the magnetic forces generated by the two first magnets 31 in each recess 300 can be superimposed and will not cancel each other out, thereby enabling the first plate 30 to be more firmly pressed against the second plate 40 (please refer to the second plate 40).

The second magnet 41 can be a magnet with opposite polarity to the first magnet 31. The second magnet 41 can also be an iron block.

The arrangement directions of the two groups of convex parts 400 can be arranged parallel to each other. The convex parts 400 and the concave parts 300 are each arranged in at least two groups, which can further increase the friction force of the first magnetic component 3 and the second magnetic component 4 on the clamped object 2.

[0049] like Figure 4 As shown, optionally, the number of the second magnets 41 is two, and the two second magnets 41 are located in the section between at least two groups of protrusions 400 on the second plate 40.

[0050] like Figure 4 As shown, if there are multiple groups of protrusions 400, the two second magnets 41 can be located in the section between the two groups of protrusions 400 with the smallest distance on the second plate 40. If the two second magnets 41 are located in the section between at least two groups of protrusions 400 on the second plate 40, the moments of the magnetic forces generated by the two second magnets 41 on each protrusion 400 can be superimposed and will not cancel each other out, thereby enabling the second plate 40 to be more firmly pressed against the first plate 30 (please refer to the first plate 30).
