站在2026年回望,蓝牙音频芯片产业已完成一次根本性的范式转移。设备不再仅仅是扬声器或耳机;它是一个情境感知的智能听觉节点。这一演进由已超越传统角色的芯片驱动,它们正成为传感器融合、实时AI处理和个性化健康监测的复杂枢纽。当前的竞争格局由三大交织的宏观趋势定义:主权芯片生态、边缘原生生成式音频,以及对无形计算的追求。 第一部分:基础技术的成熟 产业的基底层已经固化,设定了较高的准入门槛: LE Audio成为无处不在的基础设施: LE Audio现已成为绝对基线。LC3系列编解码器被普遍采用,Auracast广播音频已在利基但高价值的应用中找到节奏:旅游业的多语言支持、真正无障碍的公共场所,以及活动中可选择、凭票接入的音频体验。芯片设计师的焦点在于完善超可靠、低延迟的多流管理,以实现手机、笔记本电脑、手表和物联网设备间的无缝交互。 从“计算音频”到“认知音频”: 音频SoC中专用的AI加速器(NPU)现在已是不可或缺的标配。其角色已从实现功能演进为驱动自主音频情境管理。芯片现在可以根据学习到的用户行为、生物信号和环境声学,预测性地混合噪音控制、调整空间音频渲染并优先处理通信提醒——所有这些都以毫瓦级的功耗运行。 第二部分:2026年的核心战场 主权芯片战略:最深刻的转变是向垂直整合、特定应用芯片的迈进。主流OEM厂商已不再满足于通用的商用芯片。...
