Abstract
A kind of backup formula is taken one's seat microphone, including microphone case, it is characterized in that, the first pick-up head and the second pick-up head are provided with described microphone case, the connection corresponding with the input of built-in circuit respectively of two electrodes of the first pick-up head, the connection corresponding with the input of analog pickup system of the output end of built-in circuit；The connection corresponding with extemporaneous conference system speech equipment of second pick-up head；The microphone case is connected with the ground wire of extemporaneous conference speech equipment.The utility model has the advantages that：By the improvement to microphone built-in function of taking one's seat, extemporaneous meeting microphone is set to have the function that analog pickup is ensured.Reliable analog pickup backup can be provided for the extemporaneous conference system of high-grade meeting to ensure.And in appearance, there is no difference with general extemporaneous meeting microphone in acoustical behavior, meet the requirement of high-grade meeting.
Description
Technical field
The utility model is related to a kind of extemporaneous microphone of backup formula, is mainly used in being used for conference amplifying system.
Background technology
Conference amplifying system by main frame, Zhu Xiji, represent the equipment such as machine be connected with each other constitute.Extemporaneous microphone is and chairman
Machine, represent machine etc. be used for spokesman equipment be connected, the equipment with pickup function.Use the meeting public address system of extemporaneous microphone
Line of uniting is complicated, and equipment is various, analog signal and data signal multiple conversions.Compared to using common microphone connect it is analog
Pickup system, reliability is relatively low, it is possible to the hidden danger for causing meeting to interrupt occur.But extemporaneous microphone conference amplifying system
Feature is stronger, even if needing the meeting occasion of high reliability, it is also necessary to use extemporaneous microphone conference system.If in order to protect
The reliability that card pickup amplifies, then a common microphone is placed on the table, desktop can be made not clean and tidy enough, do not met high-grade
The requirement of meeting.
The content of the invention
The utility model aims to provide a kind of extemporaneous microphone of backup formula, on the basis of microphone quantity is not increased,
The a set of analog microphone unit of increase, realizes the backup to pickup system in extemporaneous microphone.Solve prior art exist
A common microphone is placed on desktop as backup, desktop can be made not clean and tidy enough, the problem of not meeting high-grade requested session.
The technical solution of the utility model is：A kind of backup formula is taken one's seat microphone, including microphone case, and its feature exists
In, be provided with the first pick-up head and the second pick-up head in described microphone case, two electrodes of the first pick-up head respectively with
The input correspondence of built-in circuit is connected, the connection corresponding with the input of analog pickup system of the output end of built-in circuit；The
The connection corresponding with extemporaneous conference system speech equipment of two pick-up heads；The microphone case and the ground wire phase of extemporaneous conference speech equipment
Even.
The output end of described built-in circuit and the input of analog pickup system are connected using the CANNON connecting line of standard
Connect.
Parallel resistance and electric capacity between the earth terminal and microphone case that described built-in circuit is exported.
The utility model has the advantages that：By the improvement to microphone built-in function of taking one's seat, gather around extemporaneous meeting microphone
There is the function that analog pickup is ensured.Reliable analog pickup backup can be provided for the extemporaneous conference system of high-grade meeting
Ensure.And in appearance, there is no difference with general extemporaneous meeting microphone in acoustical behavior, meet wanting for high-grade meeting
Ask.
Brief description of the drawings
Fig. 1 is the general structure schematic diagram of the utility model embodiment.
Description of reference numerals：1st, backup formula is taken one's seat microphone, and 2, analog pickup system, 3, extemporaneous conference system speech sets
It is standby, the 4, first pick-up head, the 5, second pick-up head, 6, built-in circuit, 7, microphone case, a, the pin of three pin CANNON plug 1, b, three pins
The pin of CANNON plug 2, c, the pin of three pin CANNON plug 3, d, pick-up head positive pole, e, pick-up head negative pole, f, earth terminal.
Embodiment
Referring to Fig. 1, the inside of the extemporaneous microphone 1 of the utility model backup formula has the first pick-up head 4 and the second pick-up head
5, the first pick-up head 4 provides power supply and pickoff signals by built-in circuit 6, and built-in circuit 6 is with analog pickup system 2 by standard card
You connect connecting line.Second pick-up head 5 is directly connected with extemporaneous conference system speech equipment 3, is set by extemporaneous conference system speech
Standby 3 provide power supply and pickoff signals.The microphone case 7 and the ground wire of extemporaneous conference speech equipment 3 of the extemporaneous microphone 1 of backup formula
It is connected, for anti-interference protection.Usually, in order to avoid the interference and impact of ground wire between different system, in analog pickup
The earth terminal of the built-in circuit 6 of system（1 pin）With microphone case 7 parallel resistance R and electric capacity C（For routine techniques）.
Described analog pickup system 2, extemporaneous conference system speech equipment 3 and built-in circuit 6 is routine techniques.
