Abrégé

Disclosed in the present invention is a sound system, comprising an accommodating tube, and a loudspeaker arranged in the accommodating tube. A sound source device transmits audio power to the loudspeaker, the loudspeaker converts the audio power into sound waves and emits the sound waves, and the loudspeaker is arranged in the same direction as the accommodating tube and partitions an inner cavity of the accommodating tube into a front cavity and a rear cavity. Specifically, a front end of the loudspeaker and the accommodating tube enclose the front cavity to form a resonance chamber, such that the sound waves emitted by the loudspeaker are superposed and amplified, push surrounding air via a tube wall of the accommodating tube, and are transmitted to eardrums of people; and a rear end of the loudspeaker and the accommodating tube enclose the rear cavity, such that the sound waves rush out of an exhaust hole to form mega bass. The front cavity and the rear cavity are isolated from each other, so as to effectively prevent distortion caused by superposition of the sound waves. In addition, the sound waves in the front and rear directions of the loudspeaker are used, such that the tone quality of the sound system is improved. Further provided in the present invention are a sunshade umbrella, swing and tent comprising the sound system. An auditory sense requirement is met while original attributes thereof are kept, such that the user experience is improved.

Abrégé

The present invention discloses an intelligent outdoor umbrella, including an umbrella body, and angle adjustment mechanism configured to adjust an angle in a vertical direction, a rotation mechanism configured to adjust an angle in a horizontal direction, a lifting mechanism, an environment monitoring mechanism and a main controller. An angle of an outdoor umbrella is automatically adjusted to follow the change in the sun angle and better achieve the purpose of shading. The lifting mechanism enables the outdoor umbrella to fold and unfold automatically. The environment monitoring mechanism includes a solar assembly and a wind speed measurement device, the direction of sunlight and the wind speed are monitored and the measured related data is transmitted to the main controller.
