Description

Shockproof structure for desktop microphone and desktop microphone Technical Field The present invention relates to the field of microphones, and more particularly, to a vibration-proof structure for a desktop microphone and a desktop microphone having the same. Background The desktop microphone is used as a high-sensitivity sound collection device and is widely applied to scenes such as meeting offices, game live broadcasting, recording production and the like. Because the microphone assembly is very sensitive to vibration, mechanical vibration (such as keyboard knocking sound, cup placement sound or table body collision sound) conducted by the table top is extremely easy to be captured by the microphone assembly, low-frequency noise (such as booming sound) is formed, and recording quality is seriously affected. Thus, the vibration-proof structure is an integral part of the table microphone. The existing desktop microphone shockproof scheme is mainly divided into an external type and an internal type, but certain limitations exist: An external suspension type vibration-proof frame (commonly called as a spider frame) is characterized in that the microphone is suspended at the center of the external support through an elastic rope or a rubber band. Although the shock attenuation effect is better, its volume is huge, the structure is complicated, not only occupies valuable desktop space, but also shelters from user's face in live video or meeting easily, influences visual pleasing to the eye and uses experience. In addition, the rubber band needs to be replaced frequently after ageing and loosening, and the maintenance cost is high. In order to pursue attractive appearance and small size, a part of microphones are tried to be built in the vibration-proof structure. However, existing built-in solutions are typically simply filling a simple rubber block or foam pad between the microphone assembly and the housing. This approach relies solely on the elasticity of the material itself for passive damping, lacking an effective cushioning stroke and damping medium. When receiving great impact or low frequency vibration, simple rubber structure takes place excessive deformation easily and leads to "bottoming" hard contact, perhaps can't effectively dissipate vibration energy, leads to shockproof effect far inferior as external shock absorber frame. Disclosure of Invention Aiming at the problems that the external suspension type vibration-proof frame in the prior art is huge in size and can block the sight, and the traditional built-in simple vibration-proof structure is easy to generate 'bottoming' hard contact and has poor low-frequency vibration-proof effect, the invention provides the vibration-proof structure for the desktop microphone, and solves the technical problems. The technical scheme adopted for solving the technical problems is that the shockproof structure for the desktop microphone comprises a supporting component and an elastic shock absorption frame. The microphone assembly comprises a microphone assembly, a support assembly and an elastic shock absorption frame, wherein the support assembly is provided with a containing cavity and a first opening communicated with the containing cavity, the first opening is used for installing the microphone assembly, so that the microphone assembly can be partially placed in the containing cavity, the elastic shock absorption frame is provided with a first elastic buffer part, the elastic shock absorption frame is installed at the first opening and sleeved with the microphone assembly, the first elastic buffer part is located between the microphone assembly and the support assembly, the elastic shock absorption frame and the inner wall of the containing cavity enclose to form a shock absorption cavity, when the microphone assembly is subjected to external vibration, air in the shock absorption cavity forms an air buffer layer, and elastic deformation of the first elastic buffer part matched with the elastic shock absorption frame is used for buffering and absorbing the microphone assembly. The vibration-proof structure for the desktop microphone has the beneficial effects that the vibration-proof structure for the desktop microphone is provided, the vibration-proof cavity is formed by surrounding the inner wall of the accommodating cavity of the supporting component, when the microphone component is subjected to vibration from the desktop or the outside, air in the vibration-proof cavity can form the air buffer layer with a certain damping characteristic in the vibration transmission process, and the air buffer layer can effectively prevent the direct transmission of vibration energy. Meanwhile, the first elastic buffer part of the elastic shock-absorbing frame is elastically deformed under the action of vibration, and the elastic restoring force of the material of the first elastic buffer part is utilized to further absorb and buffer vibration impact.
