Description

Technical Field

[0001] The utility model relates to the technical field of sound box speakers, and more specifically, to a waterproof sound box speaker. Background Art

[0002] There are several different types of horns. One is a wind instrument, thin at the top and thick at the bottom, mostly made of copper. The other is a modern electroacoustic component, which converts electrical signals into sound, also called a speaker. The horn is actually a device that converts electrical energy into sound. When different electronic energies are transmitted to the coil, the coil generates an energy that interacts with the magnetic field of the magnet. This interaction causes the paper plate to vibrate. Because the electronic energy changes at any time, the coil of the horn will move forward or backward, so the paper plate of the horn will move with it. This action changes the density of the air and produces sound.

[0003] The existing speakers do not have a dust-proof structure. After the speakers are used for a long time, a large amount of dust will accumulate in the speakers. Since multi-speaker speakers have more speakers, it is not easy to clean the dust after it enters, thus affecting the sound quality of the speakers. Secondly, the existing speakers do not have a waterproof function. If water is accidentally spilled into the speaker during use, the multi-speaker speakers will be damaged.

[0004] After searching, the Chinese patent with publication number CN218603583U discloses a multi-speaker speaker with waterproof and dustproof functions. By setting up a protective shell and a hinged dustproof door, and combining with a sealing strip, the speaker body can be dustproof and waterproof, preventing dust and water from entering the speaker, thereby increasing the service life of the speaker. Secondly, by utilizing the sliding connection between the slide rail and the connecting plate, the dust removal component can be moved to the corresponding speaker position, and the speaker that has entered dust or water stains can be cleaned to prevent dust and water from entering the speaker body.

[0005] When the above-mentioned multi-speaker speaker with waterproof and dustproof function is actually used, the audio equipment needs to be used outdoors or in a humid environment. The equipment may be damaged or its performance may be degraded due to moisture intrusion. At the same time, moisture may change the vibration characteristics of the speaker, causing distortion or degradation of the sound quality, affecting the quality and volume of the sound.
