Description

Technical Field

[0001] The utility model belongs to the technical field of vehicles, and specifically relates to a vehicle-mounted resonance sound-generating device. Background Art

[0002] Due to the need for entertainment while driving, vehicles are usually equipped with car audio systems to play radio songs and other entertainment. It is a common car-mounted device.

[0003] Patent No. 201420864345.7, published on July 1, 2015, discloses a vehicle-mounted audio system. The system comprises a frame that fits within the central space of a vehicle tire. The frame comprises a base ring and a receiving ring. Multiple support bars are positioned between the outer side of the base ring and the lower end of the receiving ring. The central portion of the frame forms a receiving space within which a voice coil and a damper are located. The upper ends of the support bars are connected to an intermediate ring, which is connected to a low-frequency resonance plate. A low-frequency adjustment assembly is sleeved within the central portion of the low-frequency resonance plate, which is connected to the voice coil. A rubber ring is positioned between the low-frequency resonance plate and the receiving ring. The vehicle-mounted audio system is mounted on the spare tire of the vehicle, forming the speaker's enclosure. Low-pitched sounds are transmitted directly through the vehicle body, resulting in excellent audio quality. The system also takes up minimal space within the vehicle, making it convenient to use.

[0004] Due to the limitations of the installation position of car speakers, such as outdoor speakers installed at the bottom of the car, tweeters are limited by the A-pillar shape and installation structure, and the requirements of speaker directionality, some application scenarios and sound effects are poor and arbitrary.
