Abstract
For the microphone of videoconference.The utility model relates to microphone field, particularly relate to the improvement of the structure for the microphone in videoconference, propose a kind of delicate structure, stability is high, use post echo and eradicating efficacy of uttering long and high-pitched sounds is good, without the microphone for videoconference repeatedly, the utility model is when debugging, operating personnel only need to microphone towards adjusting, make microphone axially just to the mouth of call personnel; After this, the sound that vibrating membrane and vibration acquisition device will only gather the just right call personnel of microphone and send, and then to echo issuable during videoconference with utter long and high-pitched sounds and carried out effective elimination structure.Have debud mode simple, debugging efficiency is high, the good and nothing feature repeatedly of echo, eradicating efficacy of uttering long and high-pitched sounds.
Description
Technical field
The utility model relates to microphone field, particularly relates to the improvement of the structure for the microphone in videoconference.
Background technology
At present, in daily teleconference debug process, main produced problem is with or without image, ghost image, noiseless, echo and utter long and high-pitched sounds that these are several, wherein echo and utter long and high-pitched sounds and occupy larger proportion, make commissioning staff waste the plenty of time, energy echo and utter long and high-pitched sounds eliminate on, its debug process is loaded down with trivial details, and debugging after stability still not high.Like this, how to reduce operating personnel to being wasted in echo and the time on eliminating of uttering long and high-pitched sounds, and effectively ensure echo and utter long and high-pitched sounds can not repeatedly occur becoming those skilled in the art's technical problem urgently to be resolved hurrily.
Utility model content
The utility model, for above problem, proposes a kind of delicate structure, stability is high, uses post echo and eradicating efficacy of uttering long and high-pitched sounds is good, without the microphone for videoconference repeatedly.
The technical solution of the utility model is: comprise wire, base, housing, sound insulation cylinder, vibrating membrane and vibration acquisition device;
Described housing is straight-tube shape and is made up of metal material, and the root edge of described housing is fixedly connected on the end face of base; Described sound insulation cylinder is straight-tube shape and is made up of Sound-proof material, and the end face that the root edge of described sound insulation cylinder is fixedly connected on base is arranged with housing concentric; The outer wall of described sound insulation cylinder be corrugated and and leave gap between the inwall of housing;
The end face that described vibration acquisition device is fixedly connected on base is positioned at sound insulation cylinder, described vibrating membrane is connected to the top of vibration acquisition device and is connected to the bottom of sound insulation cylinder along the radial direction of sound insulation cylinder, and the top of described wire is run through described base and is connected with vibration acquisition device.
The outer wall of described sound insulation cylinder has lug boss and depressed part, and the inwall of described housing is fixedly connected with some poles, and described pole to be arranged and pole is against on the depressed part of sound insulation cylinder away from one end of housing along the radial direction of housing.
The back taper planar that the top of the inwall of described sound insulation cylinder is big up and small down.
The utility model when debugging, operating personnel only need to microphone towards adjusting, make microphone axially just to the mouth of call personnel; After this, the sound that vibrating membrane and vibration acquisition device will only gather the just right call personnel of microphone and send, and then to echo issuable during videoconference with utter long and high-pitched sounds and carried out effective elimination structure.Have debud mode simple, debugging efficiency is high, the good and nothing feature repeatedly of echo, eradicating efficacy of uttering long and high-pitched sounds.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model;
In figure, 1 is wire, and 2 is bases, and 3 is housings, and 30 is poles, and 4 is sound insulation cylinders, and 41 is lug bosses, and 42 is depressed parts, and 5 is vibrating membranes, and 6 is vibration acquisition devices.
Embodiment
The utility model as shown in Figure 1, comprises wire 1, base 2, housing 3, sound insulation cylinder 4, vibrating membrane 5 and vibration acquisition device 6;
Described housing 3 is straight-tube shape and is made up of metal material, and the root edge of described housing 3 is fixedly connected on the end face of base 2; Described sound insulation cylinder 4 is in straight-tube shape and be made up of Sound-proof material, and the end face that the root edge of described sound insulation cylinder 4 is fixedly connected on base 2 is arranged with housing 3 concentric; The outer wall of described sound insulation cylinder 4 be corrugated and and leave gap between the inwall of housing 3;
The end face that described vibration acquisition device 6 is fixedly connected on base 2 is positioned at sound insulation cylinder 4, described vibrating membrane 5 is connected to the top of vibration acquisition device 6 and is connected to the bottom of sound insulation cylinder 4 along the radial direction of sound insulation cylinder 4, and the top of described wire 1 is run through described base 2 and is connected with vibration acquisition device 6.During debugging, operating personnel only need to microphone towards adjusting, make microphone axially just to the mouth of call personnel; Like this, by the setting in sound insulation cylinder and gap, the source of sound that can import into for the axis of non-sound insulation cylinder is effectively isolated and filters, thus the sound making vibrating membrane and vibration acquisition device only gather the just right call personnel of microphone to send, and then to echo issuable during videoconference with utter long and high-pitched sounds and carried out effective elimination structure.
The outer wall of described sound insulation cylinder 4 has lug boss 41 and depressed part 42, and the inwall of described housing 3 is fixedly connected with some poles 30, and described pole 30 to be arranged and pole 30 is against on the depressed part 42 of sound insulation cylinder 4 away from one end of housing 3 along the radial direction of housing 3.Like this, effectively improved the connective stability of sound insulation cylinder by pole while, effectively strengthen for microphone side to the filtration of the source of sound transmitted and elimination, thus improve this case further to echo and the eradicating efficacy of uttering long and high-pitched sounds.
The back taper planar that the top of the inwall of described sound insulation cylinder 4 is big up and small down.Thus to by import into above microphone and and the axially inconsistent source of sound of sound insulation cylinder carry out further effectively filtering, thus effectively strengthen this case to echo and the eradicating efficacy of uttering long and high-pitched sounds.
