blaster 驅動

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.

您的手機有可能帶有IR blaster(盡管在不斷下降)。這些功能使您的電話可以使用看不見的電磁輻射與家庭中的日常設備進行通信，例如電視和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?

如果您常年丟失遙控器，則配備紅外發射器的手機非常方便。但是它們如何工作，在哪里可以買到？

紅外當王 (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.

某個年齡的讀者可能會記得使用紅外線在他們的手機，PDA或計算機之間共享文件和Internet連接。此功能(稱為“ IrDA ”)在1990年代和20年代初出現在藍牙和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.

當時，IrDA是革命性的，但是很久以來就不再是主流。現代數據傳輸技術簡直更好。借助藍牙和IrDA，兩個紅外端口都不必太靠近或沒有視線。

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.

它們也明顯更快。我的Apple PowerBook G3上的IrDA端口以緩慢的230.4 kbps速率最大。相比之下，藍牙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，甚至可以達到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.

值得強調的是，IR blaster與過去的IrDA舊港口不同。他們使用了一種完全不同的協議，稱為“消費紅外(cIR)”，并且運行速度要慢得多。

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

這意味著您將不得不忘記使用閃亮的新手機連接到90年代后期的筆記本電腦。

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.

紅外發射器幾乎專門用于控制其他設備，例如電視，機頂盒和空調裝置。通過下載應用程序，您可以有效地將手機變成通用遙控器，并控制整個世界。

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.

由于用于電視和機頂盒的IR發射器非常普遍，因此Microsoft的Xbox One的Kinect也集成了一個。這就是Kinect硬件讓Xbox One控制電視的方式。

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.

某些電話(例如Unihertz Jelly 2)預裝了通用遠程應用程序。如果您沒有，則Google Play商店中有很多選擇。

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

精益遠程是最好的之一，它為家用電器提供廣泛的支持。當然，您的里程會有所不同。

很少有美國電話提供IR沖擊波 (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手機通常配備IR blaster。三星和LG等制造商已將它們包含在設備中，但是這種情況逐漸停止了。但是，IR blaster仍然經常從華為和小米等中國制造商的手機上發貨。

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

以下是一些提供IR blaster的最新手機。

TCL 10專業版 (TCL 10 Pro)

TCLTCL

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在其頂級手機上配備了紅外發射器也就不足為奇了。畢竟，這個中國科技品牌以價格實惠的智能電視而聞名，并具有明顯的協同效應。

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.

四相機TCL 10 Pro售價449美元，提供高通Snapdragon 675、128 GB存儲，6 GB RAM和高6.47英寸顯示屏。還有一個3.5毫米耳機插Kong，這在當今已經很少見了。

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

這是在美國銷售的為數不多的帶有紅外發射器的手機之一

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結合了旗艦級規格，例如Qualcomm Snapdragon 865處理器和64 MP四攝相機設置，價格低于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.

這是美國發售的少數小米手機之一。雖然該公司尚未正式進入美國智能手機市場，但它已被經銷商廣泛進口，因此可以在亞馬遜上找到。

華為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.

華為P30 Pro新版于今年早些時候發布，是陷入困境的中國科技巨頭去年旗艦產品的適度更新版本。

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.

與華為最近的其他手機不同，該設備包括Google專有的Android應用，因此可以訪問Google Play商店。默認情況下，它具有8 GB的RAM和256 GB的存儲，是的，有一個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新版在美國不易買到，盡管在歐洲以800美元左右的價格廣泛出售。

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.

當我說紅外線沖擊波變得越來越稀少時，我不是在開玩笑。雖然確實可以找到它們，但是在美國銷售的設備中卻很少包含它們。

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.

幸運的是，紅外發射器背后的電子設備非常簡單。如果您方便使用烙鐵，則可以創建自己的烙鐵并將其插入手機的3.5毫米耳機插Kong。但是，您的里程會有所不同。
