保时捷柏林之声音响将用上氮化镓，令低音炮更小、更轻、更高效_我的网站

一 |     Post the global success of Pushpa, Allu Arjun has been treading a cautious path! The icon star, as he’s fondly called by his fans, has been circumspect about his subsequent moves. After a lot of dilly-dallying, Allu Arjun zeroed in on Atlee’s sci-fi thriller which the actor has been shooting for in Mumbai. While the shooting is mid-way, reports about his next film have been doing the rounds.          Allu Arjun yet to finalize     Allu Arjun intends to complete his film with Atlee by 2026 summer, and take his next film on floors by end of that year. As part of the reports have emerged that he had zeroed in on director Lokesh Kanagaraj. But the truth of the matter is that he has been in discussion with as many as five top directors – Sanjay Leela Bhansali to Prashanth Neel to Nelson Dilipkumar, Basil Joseph and Lokesh Kanagaraj – all of them have met and narrated storylines to Allu Arjun. According to sources close to the actor, he had not finalized any director yet. “Allu Arjun wanted to do stories that have universal appeal; his idea is to expand fanbase in various countries by approving scripts that attract the hinterland. Although he is excited with story ideas of a couple of directors, he wanted to give himself some time to finalize. He hasn’t signed any film yet, but intends to take it up close to wrapping up the shooting for Atlee’s large-scale, pan-Indian science-fiction action-fantasy film – that way he gets a perfect picture on his mounting appeal.”          Global collaborations     Allu Arjun has been very ambitious about collaborating with global technicians for his films. Teaming up with Studios in the West for VFX and roping in choreographers and artists from the South-East for Atlee’s film indicates his aspirations for wider appeal.     Also Read: Allu Arjun or Pawan Kalyan?

二 |      8 月 25 日消息，据外媒 motor1 今天（25 日）报道，保时捷围绕车载音响升级提交了多项专利申请，这次追求的并不是更大的音量，而是更高的效率。

三 | 保时捷称，全新的柏林之声 3D 高端环绕声音响系统，是首套采用氮化镓（GaN）并达到量产条件的车载音响系统。这种半导体材料在手机充电器中更加常见，此前很少与跑车音响联系在一起。氮化镓在电压转换时产生的热量明显少于汽车行业长期使用的硅芯片。保时捷首先把这项技术应用在 400W 低音炮功放上，并计划从 2027 年开始用于未来的量产车型。

四 | 保时捷强调的核心优势是效率，而不是单纯提高音量。氮化镓晶体管的开关速度比同类硅晶体管更快，转化为热量而损失的能量也更少。对于跑车来说，这项优势尤其重要，因为重量和散热一直是工程师必须兼顾的两项指标。这套系统并非单纯为了改善音质。保时捷与柏林之声和斯图加特大学鲁棒功率半导体系统研究所共同开发相关技术，项目从 2024 年春季的一台原型功放起步，重点放在提高效率和缩减硬件体积。发热量降低后，功放可以做得更小、更轻。保时捷称，散热器体积可以缩小约 20%，电容、电感等无源元件也能进一步缩小，同时维持原有输出能力。散热器所需的铝材随之减少，由于铝材生产耗能较高，制造环节的资源消耗也可以降低。现有保时捷车型不会因此获得升级。采用氮化镓技术的柏林之声音响系统将用于一款 2027 年推出的未来量产车型，本质上是一项新车硬件设计，而不是能够通过软件推送给现有车辆的功能。保时捷近年来一直把座舱作为体现技术差异的重要部分。公司此前已经为可改变车内声学效果的“隧道模式”申请专利，也为纯电车型开发过模拟换挡声音；纯电卡宴的内饰设计同样把更多功能集中到屏幕和控制界面上，而不是依赖传统实体开关。
