[0002] In modern society, audio playback devices have become an indispensable part of people's daily life, work and entertainment. As one of the key devices for audio playback, the development process of speakers is closely linked to technological progress. With the continuous development of electronic technology and acoustic technology, people's requirements for speakers are getting higher and higher. In recent years, the rise of digital audio technology has brought new opportunities for the development of speakers. Digital signal processing technology can process and optimize audio signals more precisely, improving the quality and stability of audio. At the same time, the development of wireless transmission technology has also made the use of speakers more convenient. Users can connect speakers wirelessly through Bluetooth, Wi-Fi, etc., getting rid of the shackles of traditional wired connections.
