Horizontal omnidirectional loudspeaker

Abstract

The invention discloses a horizontal omnibearing sound intensifier which improves the problems in the prior art that the installation is tedious and the size is big. The horizontal omnibearing sound intensifier comprises an alto driving loudspeaker, a middle cylinder whose input end is connected with the alto driving loudspeaker, a sound wave diffusion body whose input end is connected with an output end of the middle cylinder, and a sound gathering cover sleeving the outer part of the sound wave diffusion body. An interval, through which sound waves pass, exists between the sound wave diffusion body and the sound gathering cover, and support columns are arranged between the sound wave diffusion body and the sound gathering cover. The horizontal omnibearing sound intensifier is capable of realizing horizontal omnibearing radiation, sound interference is avoided, and sound blind areas do not exist; in addition, the horizontal omnibearing sound intensifier is convenient to install, small in size, light in weight and small in wind resistance, all-weather, and safe and reliable.

Description

technical field [0001] The invention relates to a horizontal omnidirectional loudspeaker. Background technique [0002] At present, to achieve sound reinforcement in all directions, the traditional method is to install multiple horns to amplify sound in different directions, such as figure 1 shown. Most of the existing emergency broadcasting and vehicle-mounted publicity speakers have the characteristics of light weight and high electro-acoustic conversion efficiency, so they are widely used. But there are generally the following disadvantages: [0003] 1. The installation is cumbersome and bulky. When used in vehicles or emergency places, it is easy to be blown due to too much wind resistance. As a result, it cannot play its due role at critical moments, and the consequences are unimaginable; [0004] 2. When multiple speakers are combined, because each speaker has its own frequency pointing characteristics, generally the higher the frequency, the sharper the pointing....

Problems solved by technology

As a result, it cannot play its due role at critical moments, and the consequences are unimaginable;

[0004] 2. When multiple speakers are combined, because each speaker has its own frequency pointing characteristics, generally the higher the frequency, the sharper the pointing. When two or more sound waves propagate in space, the sound phase is opposite, and the sound pressure level at this point When the sound phase is in phase, the sound pressure level at this point is obviously increased, and there is an uncontrollable sound wave interference phenomenon
