Description

Broadcasting host platform

Technical Field

The invention belongs to the technical field of broadcasting hosts, and particularly relates to a broadcasting host platform.

Background

The broadcasting host platform is the equipment that the broadcast media trade was commonly used, and the host carries out a series of works such as lecture, performance, report at the host platform rear, has placed the microphone in order to collect and enlarge host's sound on the host platform.

The existing broadcasting host stations are generally divided into the following two types: 1) the seat-standing type host platform is characterized in that a host sits behind the host platform, the host platform is low in height and large in area in the horizontal direction, and the seat-standing type host platform is suitable for news broadcasting and interview type programs; 2) standing formula host platform, host stand in host platform rear, host platform height is higher, and is less in the area of horizontal direction, is applicable to programs such as speech, debate and comprehensive talk show.

The inventors believe that the following disadvantages are present with respect to existing standing host tables:

1) when the height of a user is greatly different from that of an ordinary person (for example, less than 160cm or more than 190 cm), the requirements of different users can be met only by adjusting the height of the microphone, but the standing type host platform can cause great obstruction to the trunk of the user or the trunk of the user is mostly exposed outside the host platform, so that the image of different users behind the host platform can be influenced, and the psychological state of the user can be influenced and the exertion can be influenced if the trunk of the user is too much obstructed or too much exposed.

2) The existing standing type host platform is generally faced with field judges and audiences, the camera is far away from the host platform, and a special prompter (such as talk show programs and speech programs) is inconvenient to install at the position of the camera, so that a manuscript or a display screen of a prompter is generally placed on the upper surface of the host platform, and when the height of a user is high, the action of the user for looking at the manuscript or the display screen of the prompter at a low head is obvious, and the program effect is influenced.

3) In the prior art, the study on the aspect of the liftable host platform is related, but the partial host platform is only lifted in the vertical direction simply, and the study on the height and the width is not carried out, but the proportion of the height and the width is required to be considered in the design and manufacture process of the non-liftable host platform so as to achieve the optimal effect, and the situation that the host platform is too narrow and cannot shield the body of a user is avoided.

Disclosure of Invention
