Description

technical field [0001] The invention relates to the field of loudspeakers, in particular to a sunshade device with loudspeakers. Background technique [0002] The loudspeaker is a transducer device that converts electrical signals into acoustic signals, and the performance of the loudspeaker has a great influence on the sound quality. The loudspeaker is the weakest part in the audio equipment, but it is the most important part for the sound effect. There are many types of speakers, and their prices vary widely. Audio electric energy makes its paper cone or diaphragm vibrate and resonate (resonate) with the surrounding air through electromagnetic, piezoelectric or electrostatic effects to produce sound. People need parasols in summer to prevent skin from being sunburned, but if they want to listen to music while shading the sun, ordinary parasols cannot satisfy the function of playing music.
