Technical Field

[0001] The utility model relates to the technical field of sound boxes, in particular to an ultra-thin surface-sounding closed sound box inner cavity structure device. Background Art

[0002] A speaker is a device that can convert audio signals into sound. In layman's terms, it means that the speaker mainframe or subwoofer has a built-in power amplifier, which amplifies the audio signal and then plays it back by the speaker itself, making the sound louder. The speaker is the terminal of the entire sound system, and its function is to convert audio electrical energy into corresponding sound energy and radiate it into space. It is an extremely important component of the sound system, responsible for converting electrical signals into sound signals for direct human hearing.
