Description
Technical Field
The invention relates to the technical field of microphones, in particular to a clamping frame integrated microphone fixing and adjusting device.
Background
A microphone is used as a sound amplification apparatus for a person or a musical instrument to generate sound, and is an acoustic apparatus for converting a sound signal into an electric signal. The sensitivity of a microphone to sound from different directions may differ, referred to as the directivity of the microphone. The microphone fixing clamp and the fixing frame are mutually related, the fixing clamp is used for clamping the microphone on the premise of not damaging the shell and can easily take the microphone down at any time, the fixing frame is used for adjusting the height, the horizontal direction and the pitching angle of the microphone and the fixing clamp, and the fixing frame is fixedly connected with the fixing frame.
The microphone shell is mostly designed to have a taper, which increases the difficulty for fixing the microphone, meanwhile, the fixing clamp of the microphone needs to be simultaneously considered to be connected with the fixing frame, and the fixing clamp needs to be conveniently connected with the fixing frame and adjusted.
One of the biggest problems with the prior art microphone retaining clips is: the microphone with taper is clamped by point contact. For example, a microphone support (application number: CN 201921032572.2) of shenzhen myeli network technology limited clamps the microphone through a fixed half ring 11 and a movable half ring 12 disposed on a connecting pin 15, the bottom of the movable half ring 12 is screwed with a screw rod of an adjusting knob 13, the screw rod rotates to drive the movable half ring 12 to approach the fixed half ring 11 along the connecting pin 15, and the two forms a cylindrical clamping opening for the microphone. Although the inner walls of the fixed half ring and the movable half ring are provided with the shock-absorbing silica gel pads 14 for increasing friction force, the shock-absorbing silica gel pads 14 are provided with a plurality of convex points, and the formed clamping openings are still suitable for clamping cylinders with consistent axial diameters. Once the movable half ring is tapered, the clamping force at the front end and the rear end of the movable half ring is different, and only the front end clamps a part with a thicker diameter and the rear end clamps a part with a thinner diameter. This point grip can also cause the microphone to suddenly come loose.
In addition, the microphone fixing clamp in the prior art can only aim at a special fixing frame and cannot meet the requirement of connecting any other fixing frames. For example, a microphone fixing seat frame (application number: CN 201710348798.2) of xiamen lingrui smart technology ltd, a circular casing is used to clamp the microphone, and a snap ring 91 is integrally connected to the lower part of the circular casing. When the fixing frame is connected, the clamping ring 91 is inserted into the fixing frame and clamped and fixed between the first clamping piece 4 and the second clamping piece 5 which are clamped relatively, and the clamping ring can facilitate the adjustment of the pitching angle. However, the most significant problems with this clip are: it is only applicable to proprietary holders and the holders and clips are friction snap fit assembly parts. When singing, the microphone needs to be taken down, the microphone can only be taken out of the fixing frame together with the clamping ring and the circular ring-shaped shell, so that a singer can take the fixing clamp of the microphone more, and when the singer is unfamiliar with the fixing frame and the fixing clamp, the singer can be blinded to the microphone fixing clamp which is difficult to take down. The assembly parts have high manufacturing cost and large part volume, can be correctly installed only by adding an assembly process, and increase the installation difficulty.
Therefore, a fixing clamp design capable of adapting to microphone shells with different thicknesses and different tapers is found, the fixing clamp needs a universal connecting interface to adapt to different fixing frames, and meanwhile, the fixing clamp is designed into an integrated structure as much as possible, so that the fixing clamp becomes a bottleneck of technical development of the microphone industry.
