Description

Technical Field

[0001] This utility model relates to the field of computer technology, and in particular to a portable computer audio circuit based on the Phytium platform. Background Technology

[0002] Portable computers, as a type of easily portable computer product, have advantages such as high integration, small size, and light weight, playing an important role in people's daily work, study, and entertainment. As the performance of portable computers continues to improve and their usage scenarios become increasingly diverse, end consumers are placing higher and higher demands on the user experience. In particular, with the increasing demand from end consumers for audio and video content and for communication and interaction through audio and video, audio experience has become a crucial evaluation criterion for users' assessment of the portable computer's overall user experience.

[0003] Stereo refers to sound that has a three-dimensional quality. Most sounds in nature are stereo, such as thunder and rain. Stereo originates from the principle of multi-channel audio, using two or more independent sound channels to allow listeners to perceive the location and distribution of sound, improving information clarity and intelligibility, and enhancing the sense of presence, layering, and transparency. Compared to mono, stereo delivers a richer and more realistic auditory experience. Current portable computers typically have two speakers on the sides or bottom of the device, but their limited audio output power results in a thin, poor-quality sound, insufficient clarity, and poor low-frequency performance, failing to meet consumers' demands for high-quality stereo sound.

[0004] To address the issue of subpar audio performance in portable computers, some brands have launched high-end portable computer products equipped with more speakers. However, these products are currently based on non-domestic platforms and use non-domestic audio decoding chips. With the increasing demand for domestically produced computers in the Chinese market, there is an urgent need for a domestically developed, high-quality audio solution for portable computers.
