How to make the hardware beep sound in Mac OS X 10.6
提问by elhombre
I just want that Mac OS X 10.6 does a hardware beep sound like in open suse and other distributions. I tried following approaches
我只希望 Mac OS X 10.6 发出类似于 open suse 和其他发行版中的硬件蜂鸣声。我尝试了以下方法
Terminal -> beep = -bash: beep: command not found
终端 -> beep = -bash: beep: command not found
Terminal -> say beep = voice speaks out beep (Not a Hardware beep but awesome ;) )
终端 -> 说哔 = 声音发出哔哔声（不是硬件哔哔声，但很棒；））
applescript -> beep = Macintosh bell (I want a Hardware beep!)
applescript -> beep = Macintosh bell（我想要硬件蜂鸣声！）
Does anybody know how to make the Hardware beep in bin/bash or applescript?
有人知道如何在 bin/bash 或 applescript 中发出硬件蜂鸣声吗？

There is no "hardware beep" in macOS.
macOS 中没有“硬件提示音”。
The functionality you're thinking of is an artifact of very old (pre-1990s) IBM PC-compatible hardware. Before most computers had sound cards, most machines had a small speaker or piezo buzzer connected to one of the channels of a timer chip. This could be used to generate simple tones or beeps. Even after many computers integrated sound cards, it remained common for quite some time for computers to route this output to a separate internal speaker. More recently, many computers, especially laptops, have integrated this functionality into the onboard sound card.
您想到的功能是非常古老（1990 年代之前）IBM PC 兼容硬件的产物。在大多数计算机配备声卡之前，大多数计算机都有一个连接到定时器芯片通道之一的小型扬声器或压电蜂鸣器。这可用于生成简单的音调或蜂鸣声。即使在许多计算机集成了声卡之后，在相当长的一段时间内，计算机仍然很普遍地将此输出路由到单独的内部扬声器。最近，许多计算机，尤其是膝上型计算机，已将此功能集成到板载声卡中。
(If you're curious about the technical details of how the PC speaker interface worked, there are more details here.)
（如果您对 PC 扬声器接口如何工作的技术细节感到好奇，这里有更多详细信息。）
This hardware has never existed in Apple computers. The only audio output available is through the sound card, and the only system beep in macOS is the user's alert sound.
这种硬件从未出现在苹果电脑中。唯一可用的音频输出是通过声卡，而 macOS 中唯一的系统蜂鸣声是用户的警报声。

tput belworks in most shells.
tput bel适用于大多数 shell。
In OS X, this (and any other command that makes the bell go off) also gets you a badge if the command is executed when Terminal was not in the foreground:
在 OS X 中，如果在终端不在前台时执行该命令，则此（以及任何其他使铃声响起的命令）也会为您提供徽章：

Indeed, the following is effective and somewhat melodic:
事实上，以下内容是有效的，而且有些旋律性：
say -v Bells "dong dong dong"
[Update] Unfortunately Bells is no longer included in latest OS X. Try:
[更新] 不幸的是，最新的 OS X 中不再包含 Bells。尝试：
say -v Victoria Do your homework!
Use the following to explore voices:
使用以下方法探索声音：
say -v \?

This will loop through all the voices (works on Yosemite):
这将遍历所有声音（适用于优胜美地）：
say -v '?' | awk '{print }' | while read voice; do printf "using $voice...\n"; say -v $voice "hello, this is me using the $voice voice"; sleep 1; done

In the terminal type :
在终端类型中：
echo -e "\a"
The -e parameter tells echo to process escaped characters. As the \n is the new line character, the \a is the bell one (the same as Ctrl+G).
-e 参数告诉 echo 处理转义字符。由于 \n 是换行符，\a 是铃音（与 Ctrl+G 相同）。

Play an arbitrary alert sound with afplay
播放任意提示音 afplay
I'm surprised nobody has mentioned afplay: that's the command line program that plays arbitrary sound files. It's been around since the original releases of OS X (and NeXTSTEP, if your memory is that long).
我很惊讶没有人提到afplay：这是播放任意声音文件的命令行程序。自 OS X 的原始版本（以及 NeXTSTEP，如果您的记忆力那么长）以来，它就已经存在了。
For example, you can run this from the command line or put it in a script:
例如，您可以从命令行运行它或将其放入脚本中：
$ afplay /System/Library/Sounds/Ping.aiff
You're not limited to system sounds; one advantage of using afplayis that you can choose your own sound file as an alert. For example, you could download one of these sound filesand pick your favorite.
您不仅限于系统声音；使用的一个好处afplay是您可以选择自己的声音文件作为警报。例如，您可以下载这些声音文件之一并选择您最喜欢的。
(Extra points if you can find a recording of an Teletype Model 33 bell!)

printf "\a"
If you look at man printf, it gives you a list of escaped characters, including \a:
如果您查看man printf，它会为您提供转义字符列表，包括\a：
\a Write a <bell> character.
