There’s a chance (albeit, an ever-decreasing one) that your phone comes with an IR blaster. These allow your phone to communicate with everyday devices in your home, like TVs and DVRs, using invisible bursts of electromagnetic radiation.

您的手机有可能带有IR blaster(尽管在不断下降)。 这些功能使您的电话可以使用看不见的电磁辐射与家庭中的日常设备进行通信，例如电视和DVR。

If you’re perennially losing your remote control, phones with IR blasters are extremely handy. But how do they work, and where can you get one?

如果您常年丢失遥控器，则配备红外发射器的手机非常方便。 但是它们如何工作，在哪里可以买到？

红外当王 (When Infrared Was King)

Readers of a certain age might remember using infrared to share files and internet connections between their phone, PDA, or computer. This feature (dubbed “IrDA“) was common in the 1990s and early ’00s before Bluetooth and Wi-Fi.

某个年龄的读者可能会记得使用红外线在他们的手机，PDA或计算机之间共享文件和Internet连接。 此功能(称为“ IrDA ”)在1990年代和20年代初出现在蓝牙和Wi-Fi之前很普遍。

At the time, IrDA was revolutionary, but it’s long since ceased to be mainstream. Modern data transfer technologies are simply better. With Bluetooth and IrDA, both infrared ports don’t have to be in close proximity or have a line of sight.

当时，IrDA是革命性的，但是很久以来就不再是主流。 现代数据传输技术简直更好。 借助蓝牙和IrDA，两个红外端口都不必太靠近或没有视线。

They’re also significantly faster. The IrDA port on my Apple PowerBook G3 tops out at a sluggish 230.4 kbps. Compare that to Bluetooth 5.0, which supports speeds of up to 2 Mbps, or Wi-Fi 6, which has a base speed of 1.2 Gbps, and can even go up to 10 Gbps.

它们也明显更快。 我的Apple PowerBook G3上的IrDA端口以缓慢的230.4 kbps速率最大。 相比之下，蓝牙5.0支持最高2 Mbps的速度，或者Wi-Fi 6具有1.2 Gbps的基本速度，甚至可以达到10 Gbps。

It’s worth emphasizing that IR blasters aren’t the same as the old IrDA ports of yesteryear. They use an entirely different protocol called Consumer Infrared (cIR), and operate at much slower speeds.

值得强调的是，IR blaster与过去的IrDA旧港口不同。 他们使用了一种完全不同的协议，称为“消费红外(cIR)”，并且运行速度要慢得多。

That means you’ll have to forget about using your shiny new phone to connect to your late-’90’s laptop.

这意味着您将不得不忘记使用闪亮的新手机连接到90年代后期的笔记本电脑。

2020年IR的用途是什么？ (What Is IR Used for in 2020?)

IR blasters are almost exclusively used to control other devices, like TVs, set-top boxes, and air conditioning units. By downloading an app, you can effectively turn your phone into a universal remote and control your entire world.

红外发射器几乎专门用于控制其他设备，例如电视，机顶盒和空调装置。 通过下载应用程序，您可以有效地将手机变成通用遥控器，并控制整个世界。

Because IR blasters for TVs and set-top cable boxes are so prevalent, Microsoft’s Kinect for Xbox One incorporated one, as well. That’s how the Kinect hardware lets Xbox One control a TV.

由于用于电视和机顶盒的IR发射器非常普遍，因此Microsoft的Xbox One的Kinect也集成了一个。 这就是Kinect硬件让Xbox One控制电视的方式。

Some phones, like the Unihertz Jelly 2, come with universal remote apps preloaded. If yours doesn’t, there are options on the Google Play store.

某些电话(例如Unihertz Jelly 2)预装了通用远程应用程序。 如果您没有，则Google Play商店中有很多选择。

Lean Remote is one of the best and offers a wide range of support for household electronics. Your mileage will vary, of course.

精益远程是最好的之一，它为家用电器提供广泛的支持。 当然，您的里程会有所不同。

很少有美国电话提供IR冲击波 (Few U.S. Phones Offer IR Blasters)

In the early 2010s, Android phones routinely shipped with IR blasters. Manufacturers like Samsung and LG included them on their devices, but this gradually stopped. However, IR blasters are still frequently shipped on phones from Chinese manufacturers, like Huawei and Xiaomi.

在2010年代初期，Android手机通常配备IR blaster。 三星和LG等制造商已将它们包含在设备中，但是这种情况逐渐停止了。 但是，IR blaster仍然经常从华为和小米等中国制造商的手机上发货。

Below are a few of the latest phones that offer IR blasters.

以下是一些提供IR blaster的最新手机。

TCL 10专业版 (TCL 10 Pro)

It shouldn’t be surprising that TCL ships an infrared blaster on its top-tier phones. After all, the Chinese tech brand is most widely known for its affordable smart TVs, and there are obvious synergies.

TCL在其顶级手机上配备了红外发射器也就不足为奇了。 毕竟，这个中国科技品牌以价格实惠的智能电视而闻名，并具有明显的协同效应。

Priced at $449, the quad-camera TCL 10 Pro offers a Qualcomm Snapdragon 675, 128 GB of storage, 6 GB of RAM, and a tall, 6.47-inch display. There’s also a 3.5mm headphone jack which is somewhat of a rarity these days.

四相机TCL 10 Pro售价449美元，提供高通Snapdragon 675、128 GB存储，6 GB RAM和高6.47英寸显示屏。 还有一个3.5毫米耳机插Kong，这在当今已经很少见了。

It’s one of the few phones with an IR blaster sold in the U.S.

这是在美国销售的为数不多的带有红外发射器的手机之一

小米Poco F2 Pro(Xiaomi Poco F2 Pro)

Xiaomi’s Poco F2 Pro combines flagship-level specs, like a Qualcomm Snapdragon 865 processor and 64 MP quad-camera setup, with a sub-$500 price tag.

小米的Poco F2 Pro结合了旗舰级规格，例如Qualcomm Snapdragon 865处理器和64 MP四摄相机设置，价格低于500美元。

This is one of the few Xiaomi phones available in the U.S. While the firm hasn’t formally entered the American smartphone market, it’s been widely imported by resellers, and thus, can be found on Amazon.

这是美国发售的少数小米手机之一。虽然该公司尚未正式进入美国智能手机市场，但它已被经销商广泛进口，因此可以在亚马逊上找到。

华为P30 Pro新版 (Huawei P30 Pro New Edition)

Announced earlier this year, the Huawei P30 Pro New Edition is a modestly updated version of last year’s flagship from the embattled Chinese tech giant.

华为P30 Pro新版于今年早些时候发布，是陷入困境的中国科技巨头去年旗舰产品的适度更新版本。

Unlike other recent phones from Huawei, this device includes Google’s proprietary Android apps, so it has access to the Google Play store. It comes with 8 GB of RAM and 256 GB of storage by default, and, yes, there’s an IR blaster.

与华为最近的其他手机不同，该设备包括Google专有的Android应用，因此可以访问Google Play商店。 默认情况下，它具有8 GB的RAM和256 GB的存储，是的，有一个IR blaster。

The P30 Pro New Edition isn’t readily available in the U.S., although it’s widely sold in Europe for around $800.

P30 Pro新版在美国不易买到，尽管在欧洲以800美元左右的价格广泛出售。

自己做 (Make Your Own)

I wasn’t joking when I said IR blasters were getting rarer. While it’s certainly true that they can be found, very few are included on devices sold in the U.S.

当我说红外线冲击波变得越来越稀少时，我不是在开玩笑。 虽然确实可以找到它们，但是在美国销售的设备中却很少包含它们。

Fortunately, the electronics behind an IR blaster are extremely simple. If you’re handy with a soldering iron, it’s possible to create your own and plug it into your phone’s 3.5mm headphone jack. Your mileage will vary, however.

幸运的是，红外发射器背后的电子设备非常简单。 如果您方便使用烙铁，则可以创建自己的烙铁并将其插入手机的3.5毫米耳机插Kong。 但是，您的里程会有所不同。
