Description

Technical Field

[0001] This utility model relates to the field of audio equipment technology, and in particular to a Bluetooth speaker that integrates motorcycle turn signals. Background Technology

[0002] With the development of science and technology, people's living standards have greatly improved. Cars and motorcycles are indispensable means of transportation. 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 CN223432410U discloses a motorcycle audio system, comprising an audio body with a leather sleeve fitted over its outer surface. Several fixing straps are fixedly connected to the outer surface of the leather sleeve, and two fixing rings are fixedly connected to the outer surface of the leather sleeve. Each fixing ring's outer surface engages with a corresponding fixing strap. This motorcycle audio system utilizes the fixing straps to secure the fixing rings, making the connecting post more stable. By placing the clamping plates at the handlebars in front of the motorcycle and rotating the rotating wheel, the rotation of the wheel drives the corresponding bidirectional screw to rotate. The rotation of the bidirectional screw causes the two clamping plates to move simultaneously along the corresponding bidirectional screw in opposite directions, thus quickly clamping the motorcycle. This allows the device to quickly clamp motorcycle handlebars of different sizes through the clamping plate configuration.

[0004] While the existing motorcycle audio systems can meet basic usage needs, their functions are relatively limited, only playing music and lacking integrated turn signal functionality. Installation requires separate installation of the audio system and turn signals, occupying multiple spaces, resulting in complex wiring and higher costs. Summary of the Invention
