Description

Technical Field

[0001] The present application relates to the field of competition-level audio technology, and in particular to a portable audio system. Background Art

[0002] Speakers are an important part of audio equipment. Whether it is a music competition, speech competition or other types of competitive activities, speakers are needed to ensure the propagation and quality of sound.

[0003] When participating in national or global competitions, conventional audio equipment cannot meet the performance requirements, and high-performance, high-quality audio equipment is needed to ensure unrestricted performance. However, existing competition-level audio equipment has some shortcomings in practical applications. These competition-level audio equipment are usually bulky and large in size, and in order to meet the requirements of high, medium and low-frequency effects in different competition venues, it is often necessary to carry multiple audio equipment at a time. When transporting long distances, these increase the complexity and cost of carrying and handling.

[0004] Competition-level speakers are expensive and are easily bumped during long-distance transportation. Due to their highly sophisticated structure and professional standards, once bumped, this type of speaker may directly affect the sound quality, and thus affect the user's performance and competitiveness in competitions or performances. Therefore, additional protection measures need to be set for the speakers before transportation to prevent damage to the speakers. Overall, the existing transportation methods of speakers are relatively cumbersome and the convenience of carrying is poor, and there is still room for improvement. Utility Model Content
