Description

Technical Field

[0001] The utility model belongs to the technical field of stage speakers, and in particular relates to a lifting speaker for stage. Background Art

[0002] A speaker box is a device that converts audio signals into sound. Generally speaking, it refers to a speaker box or subwoofer box with a built-in power amplifier that amplifies the audio signal and then plays it back through the speaker itself, making the sound louder. Stage speakers are often installed on stage during performances.

[0003] Chinese patent CN213629760U discloses a height-adjustable lift-type speaker, which relates to the technical field of speaker. A height-adjustable lift-type speaker comprises a box body and a speaker, and the left and right sides of the top of the box body are respectively hinged with a box cover that cooperates with each other, and the box cover is fixedly connected to a handle; two front and rear slide rails are fixedly provided at the bottom of the box body, and two left and right movable seats are slidably connected above each slide rail, and a scissor-type lifting mechanism is hinged above the left and right movable seats, and the connecting rod ends of the scissor-type lifting mechanisms on the front and rear sides are respectively connected by connecting rods, and the two ends of the connecting rods are rotatably connected to the scissor-type lifting mechanisms on the front and rear sides; a lifting plate is provided above the scissor-type lifting mechanism, and a support frame is hinged at the upper left end of the scissor-type lifting mechanism, the top of the support frame is fixedly connected to the bottom of the lifting plate, and the upper right end of the scissor-type lifting mechanism is rotatably connected to a support roller, and the support roller is in contact with the right side of the bottom of the lifting plate.

[0004] In order to facilitate the diffusion of sound, the height of the speaker setting often needs to be changed according to different usage environments. For example, when used on a stage, the height of the speaker cannot be too low, otherwise the sound will be easily blocked by the crowd, resulting in a shorter transmission distance. In the above document, the speaker is driven up and down by a scissor-type lifting mechanism, so that the height of the speaker can be adjusted. However, when adjusting the height of the speaker, the box cover needs to be manually opened first, otherwise the speaker will hit the box cover, which is more inconvenient to use.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content
