Problems solved by technology

[0005] However, there are several deficiencies that bother consumers in the conventional audio player. First, the biggest defect of the audio player is that it is too large, which becomes a big problem for consumers with small living spaces. When the accompaniment player is damaged, how to move and discard it has become a big problem. Secondly, the system and components of the accompaniment player are complicated, and it is difficult to reduce its production and sales costs, resulting in high prices and unable to arouse consumers' desire to buy. This kind of accompaniment machine can only be used as an accompaniment, and cannot provide other functions. Because it does not have the characteristics of "multi-function", it is difficult to attract the attention of consumers. In addition, it can support multiple functions and design a product that can be easily accompanied by singing. I believe it will not only be a great boon for consumers, but also bring endless business opportunities for manufacturers.
