Abstract
A radio frequency interference-free conference microphone comprises a base, a connection rod mounted on the base, and a sound head mounted on the connection rod. A base shell, the connection rod and a sound head shell are all shell structures made of metal, and the two ends of the connection rod are movably connected with the base and the sound head through a rotating component. The utility model uses the base, the connection rod and the sound head, which all use the shells made of metal, has strong integral conductivity and excellent radio frequency interference (RFI) shielding effect, provides prominent radio frequency interference-free capacity, and prevents the radio frequency interference (such as a mobile phone) when receiving sound. Synchronously, through the connection of the rotating component, the sound head can be flexibly adjusted to pick up sound at different angles and has good sound picking-up effect. The structure is stable and reliable, and can be used for a long time without invalidating easily.
Description
Technical field
The utility model relates to a kind of conference microphone.
Background technology
Traditional conference microphone, its sound head links for copper pipe and flexible pipe add to be played glue and fixes, because most sound heads are single the sensing, the pickup angle is had relatively high expectations, and the mode of connection of flexible pipe and copper pipe, be adjusted to that angle is cumbersome accurately, repeatedly regulate the pickup direction that just can reach best possibly, because long-term frequent adjustment, the elastic force of flexible pipe can occur tired gradually, make its flexibility decrease, it is loosening also to cause copper pipe and flexible pipe cooperation place to occur.Because the elastic force of flexible pipe fatigue and copper pipe and flexible pipe cooperation place are loosening, make to be adjusted to preferable pickup direction, cause the performance that seriously influences product.Existing conference microphone base is the plastic cement structure, and the coupling part is that helical form flexible pipe segmentation combination is fixing, and poor electric conductivity does not have good shielding action, when the participant makes a phone call with mobile phone, can seal in serious " ticking " radio frequency interference sound.
The utility model content
The technical problems to be solved in the utility model provides that a kind of antijamming capability is strong, the conference microphone of constitutionally stable anti-radio frequency interference.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of conference microphone of anti-radio frequency interference, comprise base, be installed on the connecting rod on the base and be installed on sound head on the connecting rod, described base shell, connecting rod and sound head shell are the metallic shell structure, and the connecting rod two ends all flexibly connect by runner assembly and base, sound head.
Above-mentioned runner assembly comprises a columned commentaries on classics core, and the commentaries on classics core is with one outward can be relative to changeing the pivoted housing that core rotates, and connected two parts are affixed with commentaries on classics core and pivoted housing respectively.And, on the pivoted housing sidewall, having notch, it is affixed with the commentaries on classics core that connecting rod passes notch, notch shape and size and interlinking lever end size and amplitude of fluctuation coupling.
As improvement to such scheme, the connecting rod two ends all the coupling assembling by screw thread and two ends up and down to change core affixed, the pivoted housing of connecting rod lower end runner assembly is fixed in the base, the sound head is fixed on the pivoted housing of small end runner assembly.
In order to prevent pivoted housing and to change between the core and arbitrarily rock, between pivoted housing and commentaries on classics core, be provided with damped part.Described damped part is for being sandwiched in the pivoted housing inner face and changeing wave shell fragment between the core outer face.
The utility model adopts base, connecting rod and sound head all to adopt metallic casing, the monolithic conductive ability is strong, have fabulous radio frequency interference (RFI) shield effectiveness, the remarkable radio frequency interference ability that prevents is provided, be subjected to radio frequency interference (as mobile phone etc.) when avoiding radio reception; Connection by runner assembly simultaneously, but make sound head flexible pick up sound to different angles, and pickup effect is good, and this Stability Analysis of Structures is reliable, uses for a long time and is difficult for losing efficacy.
Description of drawings
Embodiment
Understand for the ease of those of ordinary skills, the utility model be further described in detail below in conjunction with accompanying drawing:
As shown in Figure 1, the conference microphone that present embodiment disclosed has good anti-radio frequency interference ability, and has stable structure.This microphone comprises base 1, connecting rod 2, sound head 3 and the runner assembly 4 that is positioned on the table top.Connecting rod 2 stands on the base 1, and sound head 3 is installed on connecting rod 2 upper ends as the pickup parts.4 of runner assemblies are installed on connecting rod 2 two ends, be used to connect connecting rod 2 with base 1, be connected connecting rod 2 and sound head 3, make connecting rod 2 with respect to swinging in the base 1 fore-and-aft direction certain angle, make the sound head 3 can be with respect to swinging in the connecting rod 2 above-below direction certain angles.
In order to realize good anti-radio frequency interference function, base 1 shell, connecting rod 2 and sound head 3 shells are the metallic shell structure, and all circuit and lead all are shielded from the housing, are subjected to radio frequency interference in the time of can effectively preventing radio reception.
Above-mentioned runner assembly 4 comprises a columned commentaries on classics core 41, being with one outside the commentaries on classics core 41 can be relative to changeing the pivoted housing 42 that core 41 rotates, the commentaries on classics core 41 of connecting rod 2 two ends runner assemblies all is fixed on connecting rod 2 ends by screw thread, and the pivoted housing 42 of connecting rod two ends runner assembly 4 about in the of 2 is affixed with sound head 3 and base 1 respectively.
Have notch 421 on pivoted housing 42 sidewalls, it is affixed with commentaries on classics core 41 that connecting rod 2 passes notch 421, notch 421 shapes and size and connecting rod 2 ends size and amplitude of fluctuation coupling.
Can not keep stable in order to prevent pivoted housing 42 and to change between the core 41 owing to connecting rod 2, sound head 2 gravity make pivoted housing 42 and change between the core 41, between pivoted housing 42 and commentaries on classics core 41, be provided with damped part 5.Damped part 5 in the present embodiment is for being sandwiched in the pivoted housing inner face and changeing wave shell fragment between the core outer face, and the friction by between wave shell fragment and pivoted housing 42 inner faces and commentaries on classics core 41 outer faces can guarantee can arbitrarily not rock between pivoted housing 42 and the commentaries on classics core 41.
Above embodiment is the preferable implementation of the utility model; in addition; all right other implementations of the utility model need to prove that any conspicuous replacement is all within the utility model protection range under the prerequisite that does not break away from the present utility model design.
