[0040] An embodiment of the present invention provides a noise suppression structure of an intelligent sound collection device, referring to Figure 1 and Figure 2 , including: a microphone body 1, a sound collection unit 2 and a first buffer component 3.
[0041] The sound collecting unit 2 is installed inside the microphone body 1 for collecting sound; the first buffer assembly 3 includes a fixing portion 31 connected to the top of the sound collecting unit 2 and a plurality of buffer arms 32 .
[0042] Two ends of each buffer arm 32 are respectively connected to the fixing portion 31 and the microphone body 1 .
[0043] This embodiment improves the installation structure of the sound collection unit 2 inside the existing microphone, and adds a first buffer component 3 inside the microphone to connect with the top of the sound collection unit 2 to suppress friction noise. Specifically, when the microphone is stored in friction, the vibration generated will be transmitted to the buffer arm 32 of the first buffer component 3. The buffer arm 32 can extend the path of vibration transmission, thereby absorbing and weakening the vibration, and avoiding the vibration from being directly transmitted to the sound collection unit 2. Specifically, the vibration transmission path is the microphone body 1, the buffer arm 32, and the fixed part 31 sound collection unit 2. Through the transmission of this path, the vibration will be greatly weakened or disappear, thereby achieving the effect of suppressing friction noise and improving user experience.
[0044] Further, refer to Figure 2The fixing part 31 is set as a circular ring structure, and the fixing part 31 is sleeved on the top of the sound collecting unit 2. In this embodiment, the fixing part 31 is in a circular ring shape, which greatly facilitates its connection with the sound collecting unit 2. When the two are connected, it only needs to be sleeved on the top of the sound collecting unit 2, so that the connection between the two is more stable. At the same time, the circular ring structure can wrap the top of the sound collecting unit 2 to ensure that it is evenly stressed, so that the installation of the sound collecting unit 2 is more stable.
[0045] Furthermore, in this embodiment, the number of buffer arms 32 can be selected according to the installation space and cost requirements of the actual microphone. The more the number of buffer arms 32, the more stable the support for the sound collection unit 2 and the better the vibration reduction effect, but the cost is high. In this embodiment, the number of buffer arms 32 is set to three, and the three buffer arms 32 can be evenly arranged along the axial direction of the fixing portion 31 to form a triangular support structure, which can ensure stable support for the sound collection unit 2 while evenly dispersing the vibration, thereby improving the vibration reduction effect. Among them, the connection between the buffer arm 32 and the microphone body 1 can be fixed by existing clamping, screw locking, bonding and other methods, which are not limited here, as long as the buffer arm 32 can be stably connected to the microphone body 1. Preferably, an opening can be opened at the end of the buffer arm 32, and a column is set in the microphone body 1, and the opening and the column are fixed by plugging, so as to facilitate the installation and removal of the buffer arm 32. Further, in this embodiment, the fixing portion 31 and the buffer arm 32 can be made in an integrated molding manner to simplify the production process and reduce the production cost.
[0046] Further, refer to Figure 3 The first buffer assembly 3 also includes a fixing ring 33 which is arranged concentrically with the fixing portion 31. The first ends of the plurality of buffer arms 32 are connected to the fixing portion 31, and the second ends of the plurality of buffer arms 32 are connected to the fixing ring 33. The fixing ring 33 is connected to the microphone body 1. In this embodiment, a fixing ring 33 is added to fix the second ends of the plurality of buffer arms 32 to the fixing ring 33 to form an integral structure. Therefore, during installation, it is not necessary to connect the plurality of buffer arms 32 to the microphone body 1 in sequence. It is only necessary to fix the fixing ring 33 in the speaker body, which simplifies the assembly method, facilitates the user to install and disassemble the first buffer assembly 3, and makes the structure more stable. The fixing ring 33 and the microphone body 1 can be fixed by existing methods such as clamping, screw locking, and bonding, which are not limited here. It can ensure that the buffer arm 32 is stably connected to the microphone body 1. At the same time, in this embodiment, the fixing portion 31, the buffer arm 32 and the fixing ring 33 can be made by an integrated molding method to simplify the production process and reduce the production cost.
[0047] Furthermore, in the above two embodiments, the buffer arm 32 is arranged in a wave shape, and can effectively buffer and absorb vibration through its own telescopic deformation along the length direction, so as to improve the vibration reduction effect. At the same time, in this embodiment, the buffer arm 32 can be made of existing elastic materials to further improve its elastic deformation ability and improve the shock absorption effect.
[0048] Furthermore, in this embodiment, in order to further enhance the vibration reduction effect, the fixing portion 31, the buffer arm 32 and the fixing ring 33 can all be made of existing elastic materials, such as rubber materials, and are made by one-piece injection molding. The production process is simple, one-time molding, high efficiency and low cost.
[0049] Further, refer to Figure 4 The noise suppression structure of the microphone also includes a second buffer component 4, which includes an outer bracket 41 and an inner bracket 42 arranged concentrically. The outer bracket 41 is connected to the microphone body 1, and the inner bracket 42 is connected to the bottom of the sound collection unit 2. A first gap 43 is provided between the outer bracket 41 and the inner bracket 42, and a plurality of vibration reduction parts 44 for connecting the outer bracket 41 and the inner bracket 42 are provided in the first gap 43.
[0050] In this embodiment, a second buffer component 4 is provided at the bottom of the sound collection unit 2, so that the sound collection unit 2 is completely fixed by the first buffer component 3 and the second buffer component 4, and does not contact the microphone body 1. Therefore, the vibration generated by the friction of the microphone body 1 can only be transmitted after being buffered and absorbed by the first buffer component 3 and the second buffer component 4, thereby effectively absorbing and eliminating the vibration, so as to further improve the vibration reduction and noise reduction effect. At the same time, in this embodiment, the microphone adopts a dynamic microphone, and the sound collection unit 2 needs to be effectively ventilated in the middle. Therefore, the first buffer component 3 and the second buffer component 4 are provided at both ends thereof to ensure that it can collect normal sound and improve the sound effect, and also ensure the installation stability of the sound collection unit 2 and the vibration reduction and noise reduction effect.
[0051] It should be understood that for a dynamic microphone, since the microphone needs to be ventilated when in use, it should be fixed in a manner that does not obstruct its venting, so as to avoid affecting its function. Figure 2 and Figure 4 As shown, the first buffer component 3 and the second buffer component 4 are both arranged in connection with the sound collecting unit 2 to avoid air-permeable areas.
[0052] Specifically, in this embodiment, the inner bracket 42 and the outer bracket 41 are configured as concentric annular structures, so that a completely closed annular first gap 43 can be formed, so that the space between the inner bracket 42 and the outer bracket 41 is completely filled with the first gap 43, and the vibration is evenly offset to improve the vibration suppression effect. Specifically, the structure of the inner bracket 42 and the outer bracket 41 can be matched according to the shape of the actual sound collection unit 2 and the microphone, and there is no limitation here. The outer bracket 41 is sleeved on the outside of the inner bracket 42 to form a concentric annular structure, so as to form a complete annular first gap 43. In this embodiment, the microphone and the sound collection unit 2 are cylindrical structures as a whole. Therefore, the inner bracket 42 and the outer bracket 41 can be set as cylindrical tubular structures to adapt to the overall shape of the microphone.
[0053] Furthermore, a plurality of vibration-damping parts 44 are provided, and the plurality of vibration-damping parts 44 are evenly arranged along the circumference of the inner bracket 42 and the outer bracket 41. By providing the vibration-damping parts 44, the overall stability of the second buffer assembly 4 can be enhanced. In this embodiment, the vibration-damping parts 44 are evenly arranged between the inner bracket 42 and the outer bracket 41, and the vibration can be evenly absorbed. Preferably, the vibration-damping parts 44 can be connected to the ends of the inner bracket 42 and the outer bracket 41 to increase the deformation space of the vibration-damping parts 44, thereby improving the vibration-damping effect.
[0054] Furthermore, the vibration damping part 44 can achieve vibration buffering by having elastic properties. In the present embodiment, the cross section of the vibration damping part 44 is preferably set to a curved surface structure, which is an arch bridge-like structure with stronger deformation ability, so as to achieve better vibration damping and energy absorption effect.
[0055] It should be noted that the inner bracket 42, the outer bracket 41 and the vibration reduction part 44 can be set as an integral structure made of elastic material to maximize the elastic performance of the second buffer component 4, thereby maximizing the vibration reduction effect. The elastic material can be any elastic material in the prior art, such as rubber, etc., and there is no limitation here.
[0056] Furthermore, the microphone body 1 includes a hand-held portion 11 and a base portion 12, and a plurality of elastic portions 45 are provided on the hand-held portion 11 and / or the base portion 12. It should be noted that when using the microphone, the user will hold the middle part of the microphone, i.e., the hand-held portion, or the bottom part of the microphone, i.e., the base portion 12. Therefore, in this embodiment, in order to meet the user's holding habits, a plurality of elastic portions 45 are provided on the hand-held portion 11 and / or the base portion 12 of the microphone, which have a certain elastic deformation capacity and can directly absorb the vibration between the user's hand and the microphone body 1 to reduce the vibration in the early stage of generation. At the same time, the friction between the user's hand and the microphone body 1 can also be increased, making it easier for the user to hold the microphone.
[0057] Specifically, refer to Figure 5The elastic portion 45 is disposed on the outer side wall of the handle portion 11 and / or the base portion 12, and the elastic portion 45 is arranged along the axial direction of the handle portion 11 and / or the base portion 12;
[0058] Alternatively, refer to Figure 7 The elastic portion 45 is disposed on the inner side wall of the handle portion 11 and / or the base portion 12 , and the elastic portion 45 is arranged along the axial direction of the handle portion 11 and / or the base portion 12 .
[0059] Further, refer to Figure 6 The elastic portion 45 is disposed on the outer side wall of the handle portion 11 and / or the base portion 12, and the elastic portion 45 is arranged along the circumference of the handle portion 11 and / or the base portion 12;
[0060] Alternatively, refer to Figure 8 The elastic portion 45 is disposed on the inner side wall of the handle portion 11 and / or the base portion 12 , and the elastic portion 45 is arranged along the circumference of the handle portion 11 and / or the base portion 12 .
[0061] In this embodiment, the elastic part 45 can be made of existing elastic materials, such as rubber material. The elastic part 45 can be fixed to the hand-held part 11 or the base part 12 by existing fixing methods, such as clamping, bonding, etc., and can also be integrally molded with the hand-held part 11 or the fixed part 31.
[0062] The above description is only an optional embodiment of the utility model, and does not limit the patent scope of the utility model.
