Detailed Description

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

Reference will now be made in detail to embodiments of the present patent, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present patent and are not to be construed as limiting the present patent.

In the description of this patent, it is to be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in the orientations and positional relationships indicated in the drawings for the convenience of describing the patent and for the simplicity of description, and are not intended to indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and are not to be considered limiting of the patent.

In the description of this patent, it is noted that unless otherwise specifically stated or limited, the terms "mounted," "connected," and "disposed" are to be construed broadly and can include, for example, fixedly connected, disposed, detachably connected, disposed, or integrally connected and disposed. The specific meaning of the above terms in this patent may be understood by those of ordinary skill in the art as appropriate.

Referring to fig. 1-3, an omnidirectional microphone for video conferencing, including casing 1 and base 4, casing 1 bottom and 4 top joints of base, make omnidirectional microphone watch pleasing to the eye through the mode of joint, and firm in connection, casing 1 top is equipped with receiving

hole

3, and 3 inner chambers of receiving hole are equipped with microphone and broadcast hole, and the microphone is equipped with 3 altogether, through being equipped with 3 microphones, make the radio reception scope wider, and the sound of collecting is more clear, casing 1 top periphery is equipped with button 2, and button 2 is including sound amplification, sound reduces, pause begins, the periphery at casing 1 top is equipped with the LED display lamp, the LED display lamp is the working signal lamp, base 4 one side is equipped with MIC interface 5 and earphone interface 6, base 4 bottom is equipped with the slipmat, through being equipped with the slipmat, prevent to take place to sideslip when placing the desktop and drop.
