[0002] With the continuous upgrading of motorcycle electronic configurations, the degree of electronic control of motorcycles is getting higher and higher. Adding a sound system to a motorcycle has become a lifestyle trend. Sound systems can play music, and many people like to listen to music while riding a motorcycle, making driving more enjoyable.

[0003] A search revealed that Chinese utility model patent CN215098031U discloses a motorcycle audio system, including a housing. Both sides of the housing have integrally formed bases, with a fixing ring fixedly connected to one side of each base. One side of the fixing ring has anti-slip textures. Two drainage grooves are formed on one side of the housing, along with multiple sound-permeable holes. A display screen is embedded in one side of the housing, and multiple buttons are located directly below the display screen. Textures are present on multiple sides of the housing. This utility model solves the problem of motorcycle audio systems being inconvenient to place on motorcycles due to the bumpy ride, thus ensuring the driver's driving experience and improving the audio system's performance. Secondly, it facilitates charging the audio system and allows connection to the driver's mobile phone, increasing its versatility. Furthermore, it helps to drain rainwater from the audio system during rainy weather.

[0004] For example, Chinese utility model patent application CN223279247U discloses a mountable motorcycle audio system, which includes: a front housing with a horn through-hole, a horn fixedly connected to the front housing, the sound-producing part of the horn being positioned corresponding to the horn through-hole, and a rear housing mounted to the front housing. The rear housing has a nut through-hole into which a mounting bolt for mounting and connecting to the motorcycle is inserted. The nut of the mounting bolt is located on the outside of the rear housing, and the mounting bolt is threadedly connected to the mounting nut. The mounting nut is located on the inside of the rear housing, and a nut mounting groove is provided on the inner wall of the rear housing to accommodate the mounting nut. This utility model discloses a mountable motorcycle audio system that ensures the entire housing of the audio system is evenly stressed when mounted on the motorcycle, reducing damage to the audio system caused by motorcycle bumps.
