[0034] An embodiment of the present invention provides a microphone with friction noise suppression, referring to Figure 1 and Figure 2 ,include:

[0035] Microphone body 1;

[0036] A sound collection unit 2, used for collecting sound;

[0037] The elastic member 3 is used to install the sound collecting unit 2 ; the elastic member 3 includes a fixing portion 31 connected to the microphone body 1 and a mounting portion 32 for mounting the sound collecting unit 2 ; a first gap 51 is provided between the mounting portion 32 and the microphone body 1 .

[0038] In this embodiment, the installation structure of the sound collection unit 2 of the existing microphone is improved, and an elastic member 3 is installed on the microphone body 1. The sound collection unit 2 is installed on the elastic member 3 and is not in direct contact with the microphone body 1. Therefore, the vibration generated by the friction of the microphone body 1 is not directly transmitted to the sound collection unit 2, thereby effectively reducing the collection of friction vibration sound by the sound collection unit 2 and effectively suppressing friction noise.

[0039] Specifically, when the microphone body 1 is subjected to friction, its vibration will be transmitted to the elastic member 3 in direct contact with it. The elastic member 3 effectively buffers the vibration through its own elasticity, thereby greatly weakening or blocking the vibration transmitted to the sound collection unit 2, thereby achieving the effect of suppressing friction noise; at the same time, the elastic member 3 includes a fixing portion 31 and a mounting portion 32, the fixing portion 31 is connected to the microphone body 1, and the mounting portion 32 is used to install the sound collection unit 2. Since a first gap 51 is provided between the mounting portion 32 and the microphone body 1, a certain vibration space can be provided to prevent the vibration from being transmitted directly to the sound collection unit 2 through the mounting portion 32. Therefore, the vibration of the microphone body 1 needs to be first transmitted to the fixing portion 31, and then transmitted from the fixing portion 31 to the mounting portion 32, and then transmitted from the mounting portion 32 to the sound collection unit 2, thereby extending the vibration transmission path, thereby further enhancing the vibration suppression effect and making the friction noise suppression effect better.

[0040] It should be noted that, in this embodiment, the elastic member 3 can be made of an elastic material, or the overall structure of the elastic member 3 can be made elastic by structural design to achieve an elastic buffering effect. Specifically, when the elastic member 3 is made of an elastic material, the mounting portion 32 can be set as a structure made of an elastic material, or the fixing portion 31 can be set as a structure made of an elastic material, or the mounting portion 32 and the fixing portion 31 can be an integrated structure made of an elastic material, and no limitation is made here. The elastic material can be made of an existing material with elastic properties such as rubber. If a material such as rubber is selected, it can be made by injection molding.

[0041] Furthermore, a second gap 52 is provided between the mounting portion 32 and the fixing portion 31; in this embodiment, the elastic member 3 can provide a certain vibration space for the mounting portion 32 and the fixing portion 31 by providing the second gap 52 between the mounting portion 32 and the fixing portion 31, thereby achieving an elastic vibration reduction effect from its structure.

[0042] Furthermore, the mounting portion 32 is connected to the fixing portion 31 via a vibration-damping portion 33. By providing the vibration-damping portion 33, while the mounting portion 32 and the fixing portion 31 are connected, when vibration passes through the elastic member 3, the vibration-damping portion 33 can effectively buffer the vibration. The vibration-damping portion 33 in this embodiment can be made of existing elastic materials.

[0043] Further, the mounting portion 32 is arranged concentrically with the fixing portion 31, and the mounting portion 32 is located inside the fixing portion 31. Figure 2 and Figure 4 In this embodiment, the mounting portion 32 and the fixing portion 31 are configured as concentric annular structures, so that a completely closed annular second gap 52 can be formed, so that the space between the mounting portion 32 and the fixing portion 31 is completely filled with the second gap 52, and the vibration is evenly offset, thereby improving the vibration suppression effect. Specifically, the structures of the mounting portion 32 and the fixing portion 31 can be matched according to the actual shapes of the sound collecting unit 2 and the microphone, and there is no limitation here. Among them, the fixing portion 31 is sleeved on the outside of the mounting portion 32 to form a concentric annular structure, so as to form a complete annular second gap 52. In this embodiment, the microphone is a cylindrical structure as a whole. Therefore, the mounting portion 32 and the fixing portion 31 can both be configured as cylindrical tubular structures to adapt to the overall shape of the microphone.

[0044] Furthermore, the vibration-damping parts 33 are provided in a plurality, and the plurality of vibration-damping parts 33 are evenly arranged along the circumference of the mounting part 32 and the fixing part 31. By providing the vibration-damping parts 33, the overall stability of the elastic structure can be enhanced. In this embodiment, the vibration-damping parts 33 are evenly arranged between the vibration-damping parts 33 and the fixing part 31, and the vibration can be evenly absorbed. Preferably, the vibration-damping parts 33 can be connected to the ends of the mounting part 32 and the fixing part 31, so as to increase the deformation space of the vibration-damping parts 33, thereby improving the vibration-damping effect.

[0045] Furthermore, the cross section of the vibration reduction part 33 is set to a curved surface structure. It should be noted that the vibration reduction part 33 has elastic properties to achieve vibration buffering. In this embodiment, the cross section of the vibration reduction part 33 is preferably set to a curved surface structure. Figure 4 It is an arch bridge-like structure with stronger deformation ability, which makes the vibration reduction and energy absorption effect better.

[0046] It should be noted that the mounting portion 32, the fixing portion 31 and the vibration-damping portion 33 can be configured as an integral structure made of an elastic material to maximize the elastic properties of the elastic member 3, thereby maximizing the vibration-damping effect. The elastic material can be any elastic material in the prior art, such as rubber, etc., and there is no limitation here.

[0047] Furthermore, in the present embodiment, the elastic member 3 can be detachably mounted on the microphone body 1, and can be fixed by an existing plug-in structure, a snap-on structure, a threaded structure, etc., or by gluing, and no specific limitation is made here.

[0048] Furthermore, the mounting portion 32 is provided with a mounting groove 321 for mounting the sound collecting unit 2. Figure 4 When installing the sound collecting unit 2, its end can be directly inserted into the installation groove 321 for installation, which is convenient for installation. When the installation portion 32 is made of elastic material, the size of the installation groove 321 can be slightly lower than the outer contour size of the sound collecting unit 2, so that the sound collecting unit 2 is wrapped and fixed by the elastic deformation of the installation groove 321, thereby improving the stability of the installation.

[0049] Furthermore, a fixing member 3 fixedly connected to the sound collecting unit 2 is provided at the bottom of the installation slot 321. In this embodiment, in order to improve the installation stability of the sound collecting unit 2, the fixing member 322 can be used to fix it. Figure 2 , Figure 3 and Figure 4 The fixing structure can be set as a screw, and a through hole 324 is opened at the bottom of the corresponding installation groove 321. A threaded hole 22 is set at the end of the sound collection unit 2. The screw passes through the through hole 324 and is connected to the threaded hole 22, so that the sound collection unit 2 is stably fixed in the installation groove 321.

[0050] Furthermore, at least one limiting groove 323 is provided on the side of the installation groove 321, and the sound collecting unit 2 is provided with a limiting protrusion 21 adapted to the limiting groove 323. In this embodiment, the sound collecting unit 2 and the installation groove 321 are provided with a positioning clamping structure of the limiting groove 323 and the limiting protrusion 21, so that the sound collecting unit 2 can be prevented from rotating in the installation groove 321, thereby ensuring the stability of the line connection. Specifically, in this embodiment, at least one or more limiting grooves 323 can be provided on the side of the installation groove 321, and the limiting grooves 323 are arranged along the axial direction of the installation groove 321. The sound collecting unit 2 is correspondingly provided with a limiting protrusion 21, and the limiting protrusion 21 is plugged in one by one with the limiting groove 323, so that the rotation of the sound collecting unit 2 can be limited. At the same time, a guide is provided during the installation process of the sound collecting unit 2, so as to facilitate the installation.

[0051] Furthermore, the microphone further comprises a mesh cover 4, the mesh cover 4 is arranged outside the sound collecting unit 2, and a third gap 53 is arranged between the sound collecting unit 2 and the mesh cover 4. It should be noted that the existing microphone usually has a mesh cover 4 to protect the internal sound collecting unit 2, and the mesh cover 4 is usually installed on the microphone body 1. Therefore, the vibration of the microphone body 1 will be directly transmitted to the mesh cover 4. In order to prevent the vibration of the mesh cover 4 from causing sound to the sound collecting unit 2, a reference is made to the mesh cover 4. Figure 2In this embodiment, a third gap 53 is provided between the mesh cover 4 and the sound collecting unit 2. The sound collecting unit 2 is not in direct contact with the mesh cover 4. The third gap 53 provides a vibration space, thereby blocking the vibration transmission between the mesh cover 4 and the sound collecting unit 2, further improving the friction noise suppression effect.

[0052] It should be noted that the sound collection unit 2 in this embodiment adopts a sound collection module in the prior art, for example, a sound collection module such as a microphone can be adopted, and no specific limitation is made here.

[0053] The above description is only an optional embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
