[0002] A speaker is an electroacoustic transducer that converts an electrical signal into an acoustic signal, and is widely used in various occasions such as media playback, gaming experience, and environmental sound effects. It provides a broad auditory experience through surround sound effects, voice effects, etc., and creates an infectious music atmosphere. In order to further improve the user experience, some speakers combine the speaker with lights to form an acoustic and light device, which provides both sound effects and light effects at the same time. For example, many car brands combine speakers with lighting lamps to make the product more interactive and technological. At present, for the acoustic and light devices on the market, an external light source is mainly combined with the speaker. The external light source and the speaker are two components.
