Abstract: Disclosed is an electro-magneto-thermo-mechanical dynamic and synchronous loading device based on a wedge-shaped rotating body. The device comprises a carrier, a wedge-shaped rotating body and a pulse power supply, wherein the wedge-shaped rotating body is positioned above the carrier, the pulse power supply is connected to the carrier and the wedge-shaped rotating body through conductors, a test object is fixed on the carrier, the top of the wedge-shaped rotating body is connected to the output end of a driving shaft through a transmission shaft, the driving shaft drives the wedge-shaped rotating body to rotate and can apply downward pressure, and the wedge-shaped rotating body can be pressed against the test object and rotate on the surface of the test object.

Abstract: The present application relates to the technical field of loudspeakers. Disclosed are a loudspeaker device, a method, apparatus and device for adjusting the sound effect thereof, and a medium. The method is used for increasing the diversity of the sound effect of the loudspeaker device, and comprises: determining the spatial distribution state of multiple loudspeaker units in the loudspeaker device; determining a sound effect mode corresponding to the spatial distribution state; and adjusting the sound effect of the loudspeaker device according to the sound effect mode. According to the present application, the sound effect mode is accordingly adjusted according to the spatial distribution state of multiple loudspeaker units in the loudspeaker device. In this way, when the spatial distribution state changes, the sound effect mode of the loudspeaker device also changes, thereby overcoming the defect of the single sound effect of the loudspeaker device, i.e.
