Description

Technical Field

[0001] The utility model belongs to the technical field of stage sound, and in particular relates to a multi-angle adjustable stage sound equipment. Background Art

[0002] Speakers are devices that convert electrical signals into sound signals. Restoring authenticity is an important criterion for evaluating speaker performance. According to the sound generation principle and internal structure, speakers can be divided into several types, such as inverted type, sealed type, flat type, horn type, and labyrinth type. The audio equipment dedicated to stage performances is collectively called stage speakers, which is an important branch of performance equipment.

[0003] However, the existing stage speakers have some shortcomings during use. The stage speakers are all installed on the stage truss and are only used to amplify the sound on the stage, so that the audience cannot feel the visual effect that the speakers can also bring, which greatly reduces the charm of the stage; when adjusting the direction, it needs to be reinstalled, the operation is cumbersome, and it is impossible to make real-time adjustments during the performance; after being fixed, the vibration of the sound of the speakers causes the angle of the speakers to deflect, affecting the performance effect.
