[0002] Active speakers belong to a sub-area of ​​speaker products. In recent years, with the continuous development of digital music content and digital sound sources, active speakers have become increasingly popular in various application scenarios due to their compact size, highly integrated equipment functions, and convenient portability and transportation. Although the current active speaker solutions highly integrate the speaker unit with the drive amplifier module, power module, audio signal receiving module, etc. in a speaker body, the specifications, sizes, and models of the speaker unit, drive amplifier module, power module, and audio signal receiving module used in each model of active speakers are different. They are all independently customized and cannot be used interchangeably. In this way, when a manufacturer of active speaker products needs to produce dozens of models in order to meet the needs of different users and respond to market demand, it is necessary to independently develop dozens of sets of speaker units, drive amplifier modules, power modules, and audio signal receiving modules for each model of active speaker products. Not only is the R&D cost very high, but the R&D cycle is also very long, the inventory of power accessories is very large, and the mold processing costs are very huge, making it impossible for manufacturers to quickly respond to the increasingly diversified and differentiated market demands, and it is difficult to keep up with and adapt to the pace of market development. Especially when a product fails and needs to be repaired, it is extremely difficult. Not only is it difficult to disassemble, but there are no universal accessories, and the after-sales cost is very high. In view of these shortcomings and difficulties of the current active speakers, the applicant believes that there is a great need for an active speaker solution that can be quickly produced and used in a new ecological model.
