Description

Technical Field

[0001] The utility model belongs to the technical field of sound boxes, and particularly relates to a waterproof structure of a sound box. Background Art

[0002] Audio, a product of modern technology, has been developing and improving since its birth. From the initial simple amplification of sound to today's high-tech applications such as surround sound and digital signal processing, every innovation in audio technology has greatly enriched our auditory experience. Whether it is the shocking sound effects in the home theater or the immersive experience at the concert, it is inseparable from the support of audio technology. With the development of society, the traditional structure of audio has gradually failed to meet the needs of the majority of users.

[0003] After searching, a Chinese patent with publication number CN216414509U discloses a waterproof structure of a speaker, including a speaker body, the speaker body including a front cover and a back cover, the front cover and the back cover enclose a cavity, a light board is provided in the cavity, lamp beads are provided on the light board, a light-emitting area is formed on the front cover, a plurality of light-emitting holes are arranged in the light-emitting area, the lamp beads are located in the light-emitting holes, a lamp cover is provided on the light-emitting area, and the lamp cover is ultrasonically welded to the front cover.

[0004] The above-mentioned audio waterproof structure in the prior art realizes waterproofing of the lamp on the speaker by connecting the lampshade and the front cover around the iron mesh through ultrasonic welding. However, when water flows down through the top of the speaker, the water will first enter the inside of the speaker along the gap of the button hole on the front cover, thereby damaging the circuit board inside the speaker or causing it to short-circuit, thereby greatly reducing the service life of the speaker.
