Description

Technical Field

[0001] The utility model relates to the technical field of angle adjustment devices, in particular to an angle adjustment device for a loudspeaker. Background Art

[0002] A loudspeaker is a device that can amplify sound and transmit it over a long distance. It usually consists of an amplifier, a wireless microphone, a volume controller, and a speaker. A loudspeaker is mainly used in situations where sound needs to be transmitted over a long distance, such as speeches, meetings, school assemblies, activities, or performances. It can make the speaker's or actor's voice loud and clear, so that the audience can hear the speech clearly without having to squeeze near the podium in the crowd.

[0003] At present, loudspeakers can be fixed to the wall through a mounting bracket when in use. However, this mounting structure is fixed and the angle cannot be adjusted, resulting in the inability to effectively adjust the sound output position, affecting the practical effect. Those skilled in the art have made relevant improvements, such as a wall-mounted speaker with adaptive multi-angle adjustment, application number CN202221732174.3. In this technical solution, the angle of the mounting plate can be adjusted by lifting the lifting sleeve to adjust the direction of the sound waves emitted by the speaker. However, the device can only adjust the angle in the vertical direction, and the speaker is not easy to disassemble and repair. To this end, we propose a loudspeaker angle adjustment device.
