Abstract

The utility model discloses a multi-head microphone which comprises a base (or a hand grab), connecting rods, microphone heads, a switch, a lead and the like, and is obviously characterized in that the plurality of connecting rods and microphone heads are arranged on the same base (or the hand grab). The multi-head microphone has the greatest advantages of firstly saving materials, namely, only one base (or the hand grab) and one lead are used for a plurality of microphones; secondly being very convenient for use, namely, the microphone does not need to be frequently transferred between an interviewer and an interviewee during the process of interview; and thirdly improving the tone quality, namely, sound signals can be collected from various angles simultaneously, thus making up the defects that the sound signals collected by the traditional microphone is unstable and a sound amplifier is easy to generate whistlers, and further having good application prospect.

Description

The bull microphone

Technical field: broadcasting equipment class

Technical background: existing microphone (microphone) mainly contains three types, and a kind of is desk-top, promptly is placed on the desktop, uses on the dais; A kind of is holding type, mainly be hand held in on-the-spot the use; Another kind is safety pin formula or earphone-type, mainly not on one's body or be worn on the head and use.

Desk-top microphone is made up of three parts, and promptly base, connecting rod and microphone head are formed, and all corresponding one by one, and promptly a microphone head has a connecting rod and a base.During use, whose front whose speech just is placed on, and uses very convenient.But a greatest weakness of this microphone is: when microphone when mouth is near, make sound amplifier produce ear-piercing uttering long and high-pitched sounds easily, and it is too far away from getting, a little less than can making signal that sound amplifier receives too again, influencing the audience listens attentively to, often seeing the meeting presider in the conference or distance that the talker often moved, regulated microphone, is exactly this reason.In addition, desk-top microphone is placed on teller's dead ahead, both had been unfavorable for that photographer photographed, be unfavorable for that also the lecturer places notebook computer and stirs speech contribution etc., thus influence lecture effect.

The holding type microphone mainly is made up of handgrip and microphone head two parts, and proficiency or both hands are caught handgrip during use, and it is just passable that microphone head is aimed at mouth, uses also very convenient.But this handgrip formula microphone uses in reporter's interview and just seems very inconvenient, that is, the interviewer must fall microphone head continually between interviewee and interviewer.Otherwise, just can not clearly record down both sides' question and answer sound.

Summary of the invention: the utility model is exactly at above two kinds of existing shortcomings of microphone, manufactures and designs a kind of new-type microphone that 2 or a plurality of microphone heads are installed on a common base or handgrip.The prime advantage one of this bull microphone is to save material, and promptly a plurality of microphones are only used a base, a lead; Two be to use convenient especially, promptly the interview in need not microphone is fallen between interviewer and interviewee; The 3rd, improve tonequality, promptly can collect sound signal from a plurality of angles simultaneously, remedied traditional microphone and collected the sound signal instability and make sound amplifier produce the shortcoming of howling easily.

Accompanying drawing: accompanying drawing is a structural representation of the present utility model.Fig. 1 is desk-top bull microphone, and [1] is base, and [2] are connecting rod, and [3] are microphone head, and [4] are switch, and [5] are lead.Fig. 2 is a holding type bull microphone, and [1] is handgrip, and [2] are connecting rod, and [3] are microphone head, and [4] are switch, and [5] are lead (or antenna).

Specific embodiments: according to design feature of the present utility model, 2～6 microphone heads [3] are installed in an end of 2～6 connecting rods [2] respectively, the other end of connecting rod [2] is installed in respectively on same base or the handgrip [1], lead with each microphone head is connected in parallel then, and linking together with total lead [5] gets final product again.

Every connecting rod [2] that is installed on base or the handgrip [1] both can be equally long, also can be different length; Its material both can be a metal, also can be nonmetal, both can make flexible pipe, also can be hard tube; Its length can be fixed, and also can be the concertina type variable-length; The connected mode of connecting rod [2] and base [1] both can be fixed, also can be to rotate 360 ° movable.Generally speaking, be criterion with convenient the use.

Claims

1. a bull microphone is made up of base [1], connecting rod [2], microphone head [3], switch [4] and lead [5], it is characterized in that: 2～6 connecting rods and 2～6 microphone heads are installed on the described same base.

2. a bull microphone is made up of handgrip [1], connecting rod [2], microphone head [3], switch [4] and antenna [5], it is characterized in that: 2～6 connecting rods and 2～6 microphone heads are installed on the described same handgrip.
