Abstract

The invention discloses a Hi-Fi active speaker, which belongs to the technical field of speakers. The Hi-Fi active speaker includes a signal source input and decoding system, a sound field high-fidelity restoration operation system, a low-distortion high-efficiency power amplifier, and an original design cavity structure. and full-range low-distortion speaker system. The signal source input and the decoding system are connected to the external signal source; the sound field high-fidelity restoration operation processing system reduces the noise of the digital signal from the decoding system, and performs the unique sound field high-fidelity restoration operation processing of the present invention on the sound field restoration; low distortion and high efficiency The power amplifier can amplify the power of the restored audio signal to promote the work of the speaker system. The original design cavity structure is an original structural design made by the present invention in combination with the inherent characteristics of the speaker used in the system. It can be realized through software processing. ‑Fi audio output function requires less hardware and less production cost, but the product has powerful functions and greatly improved reliability, thus having good social and economic benefits.

Description

technical field [0001] The invention relates to the technical field of sound boxes, more specifically, to Hi-Fi active sound boxes. Background technique [0002] Audio is an audio output device that plays an important role in people's entertainment life.
