The invention relates to the technical field of vehicle control, and discloses a sound field control method and device of a vehicle, computer equipment and a storage medium, the method comprises the following steps: in response to a scene mode trigger signal, obtaining a first real-time opening condition of a vehicle door and / or a vehicle window, determining a target sound field projection area in the vehicle based on the first real-time opening condition, generating an audio processing parameter corresponding to a loudspeaker in the vehicle; the audio signal is processed according to the audio processing parameters, and the loudspeaker is driven to project sound energy corresponding to the processed audio signal to the target sound field projection area. The target sound field projection area outside the vehicle is determined by sensing the real-time opening state of the vehicle door / window and combining the preset scene mode, and the loudspeaker parameters are adjusted; therefore, the sound energy is guided to the position of the user, the problem that the sound field in the vehicle leaks or is poor in effect when the vehicle door and the vehicle window are opened is effectively solved, and the audio experience during outdoor use is improved.

The invention discloses a finned radiator of a bidirectional protection type transformer, and belongs to the technical field of oil-immersed transformer components. Which comprises an oil inlet pipe connected with an oil outlet of the transformer, an oil return pipe connected with an oil inlet of the transformer and a group of radiating fins, and is characterized in that a protective cover rear fixing mechanism is arranged on the rear side of the oil inlet pipe, and a protective cover front fixing mechanism is arranged on the front side of the oil return pipe; a protective cover is fixed between the protective cover rear fixing mechanism and the protective cover front fixing mechanism, the left side face of the protective cover forms an opening, the upper side face, the lower side face, the front side face, the rear side face and the right side face of the protective cover form a hollow net-shaped structure, and the protective cover forms a protective cover cavity used for containing the finned radiator. The finned radiator has the advantages that birds resting on a foot can be prevented from being scalded by high-temperature radiating fins and even dying, and the surfaces of the radiating fins of the finned radiator can be prevented from being contaminated by sundries such as deadwood, residual leaves and flying catkins of external trees and bird droppings; ideal staticizing requirements are embodied, and energy is saved; and manpower resources are saved.

The invention discloses an auxiliary treatment device for thyroid surgery nurses. The auxiliary treatment device comprises a first supporting plate, a second supporting plate, an infusion protection structure, an infusion structure, a storage protection structure, a movable structure, a fixed structure, a moving structure and a supporting structure. By pulling a control valve, the angle of a first supporting plate can be adjusted under pulling of the control valve and movable rotation of a first movable shaft, angle adjustment of the first supporting plate drives angle adjustment of a pillow and a neck ring, and then angle adjustment of a storage protection structure and a movable structure is driven; therefore, angle adjustment of the fixing structure and the infusion protection structure is driven, and angle adjustment of the infusion structure is driven by angle adjustment of the infusion protection structure. The protection box slides downwards, so that the protection buckle and the protection clamping groove are separated, at the moment, the upper infusion telescopic rod is pulled out, then the upper infusion telescopic rod is pulled to form an angle suitable for infusion with the first supporting plate, and the operation is beneficial to arranging the infusion structure and the device body into a whole.
