Abstract

The invention discloses a loudspeaker box arrangement method using linear array loudspeaker boxes for sound reinforcement in a stadium. The method is one of the following methods A, B and C. The method A is as follows: the linear array loudspeaker boxes are arranged at two sides of a large screen in the stadium; the method B is as follows: the linear array loudspeaker boxes are arranged above a platform in the stadium and / or above middle audience seats opposite to the platform; and the method C is as follows: the linear array loudspeaker boxes are arranged above the central position of the stadium or at two sides of the large screen at the central position. The arrangement method can be used for overcoming the defects of the distributed design which is characterized in that the loudspeaker boxes are distributed on the roof like the illuminating lamps in a room, thus in the spacious and long-period reverberation environment of the stadium, people cannot hear clearly just like in a big public bathroom, and the installation is troublesome. The arrangement method can be used for overcoming the defects and has the advantages of small amount of loudspeaker boxes, convenience in installation, wire rod conservation, low cost and better effect. The arrangement method is widely applied to the sound reinforcement design in the stadium.

Description

technical field [0001] The invention relates to a speaker layout method using line array speakers for sound reinforcement in sports venues, which can quickly determine the placement position of the line array speakers and achieve a better sound reinforcement effect. Background technique [0002] At present, in the sound reinforcement design of international and domestic stadiums, decentralized design is adopted: that is, the speakers are placed on the roof like lighting bulbs in the room. When it is in a long reverberation environment in a large space of a stadium, the sound is like in a big bathhouse. It is not clear and there is an echo, and the installation is also very troublesome. Contents of the invention [0003] The purpose of the present invention is to provide a speaker layout method using line array speakers for sound reinforcement in sports venues, which can quickly determine the placement position of the line array speakers and achieve a better sound reinforce...
