Problems solved by technology

[0002] In the prior art, speakers can amplify the sound and increase its transmission range. However, with the development of today's society, especially in the field of performance and singing, there are more and more functional requirements for audio. Many indoor and outdoor Professional performing arts and other places need to adjust the radiation range of the sound field and the position and direction of the speakers, but most speakers are very inconvenient and inaccurate to adjust, and cannot meet the current market demand

Embodiment Construction

[0019] Such as Figure 1-Figure 3 , a sound field radiation adjustable sound box, comprising a fixed plate 2, a rotating plate 3 and a driving mechanism, the rotating plate 3 is used to install the speaker 4, so that the speaker 4 is fixed on the rotating plate 3, and the rotating plate 3 is hinged on the fixing plate 2 , the drive mechanism enables the rotating plate 3 to rotate relative to the fixed plate 2, thereby driving the speaker 4 to rotate relative to the fixed plate 2, so that the range of sound field radiation can be adjusted by driving the rotating plate 3 to rotate relative to the fixed plate 2 through the driving device.

[0020] Such as figure 1 As shown, both sides of the fixed plate 2 can be provided with rotating plates 3, and the rotating plates 3 on both sides are controlled to rotate by their corresponding driving mechanisms. The loudspeaker 4 on the rotating plate 3 on both sides is preferably a tweeter, specifically an annular belt type tweeter, compri...

Abstract

The invention discloses a sound box with adjustable sound field radiation. The sound box comprises a loudspeaker unit arranged at an upper half portion of the sound box and fixed on a rotating plate,the rotating plate is hinged to a fixed plate, the rotating plate is driven to rotate relative to the fixed plate through a driving mechanism, and a loudspeaker arranged on the rotating plate is alsodriven to rotate relative to the fixed plate so that the radiation range of a sound field can be adjusted. The radiation range of the sound field is extended and the loudspeaking efficiency is improved through the double-speaker installation mode; besides, through the left-right adjustable design of a slide block, the angle of the radiation range of the sound field can be changed, loudspeaking requirements of different places can be met, the adjustment of the radiation range of the sound field is more flexible and simpler, and convenience and rapidity are achieved.

Description

technical field [0001] The invention relates to the field of audio, in particular to a sound box with adjustable sound field radiation. Background technique [0002] In the prior art, the speaker can amplify the sound and increase its transmission range. However, with the development of today's society, especially in the field of performance and singing, there are more and more functional requirements for audio. Many indoor and outdoor Professional performing arts and other places need to adjust the radiation range of the sound field and the position and direction of the speakers, but most speakers are very inconvenient and inaccurate to adjust, and cannot meet the current market demand. Contents of the invention [0003] The present invention aims to solve the technical problems mentioned above, and provides a sound field radiation-adjustable sound box, which can change the radiation range of the sound field by sliding the position of the slider to make the adjustment mor...
