X-AudioPD: USB Power Delivery Speakers for Multichannel Audio

环绕声或多声道声音通常在电影院和文化环境中使用，例如表演和艺术画廊展览。这个市场继续稳步增长。例如，杜比全景声（Dolby Atmos）最近已被Netflix和Apple Music等主流媒体流媒体平台采用。我们的项目设想设计一个多通道音频连接标准和定制扬声器，通过使用最新版本的通用串行总线标准（USB电源传输，也称为USB PD）来利用创新技术。USB连接器已经成为连接电子配件的最常见方式。2022年，欧盟通过了新规定，要求所有便携式设备（如笔记本电脑、手机、平板电脑等）制造商从2024年起必须采用USB-C连接器。从2026年起，笔记本电脑充电器只能使用USB-C。建立这些规则可以保证减少电子垃圾，消除我们今天所面临的连接复杂性。Sonalux将利用新的USB PD标准，并将其集成到专门为多声道声音连接而设计的商用扬声器中。我们将开发一种新的标准，使环绕声扬声器能够通过单一连接器以经济实惠的水平生产，从而进入不断增长的家庭影院设备市场。

Surround or multichannel sound is commonly experienced in cinemas and in cultural contexts, such as performances and art gallery exhibitions. This market continues to grow steadily. For instance, Dolby Atmos has been recently adopted by major media streaming platforms such as Netflix and Apple Music.Our project envisions designing a multichannel audio connectivity standard and bespoke loudspeakers that exploit innovative technology by using the most recent versions of the Universal Serial Bus standard (USB Power Delivery, also known as USB PD). The USB connector has established itself as the most common way of connecting electronic accessories. In 2022, the EU passed new rules that require that all manufacturers of portable devices (e.g., laptops, phones, tablets, etc.) must adopt USB-C connectors from 2024\. From 2026, laptop chargers must only use USB-C. Establishing these rules guarantees the reduction of electronic waste and eliminates the complexity of connectivity we face today. Sonalux will take advantage of the new USB PD standard, and integrate it into commercial loudspeakers, specifically designed for the purpose of multichannel sound connectivity. We will develop a new standard that will allow the production of speakers for surround audio at an affordable level via a single connector, reaching the growing market of home-theatre equipment.
