大多数Mac机器都配备了蓝牙(Bluetooth)，使您可以将外部扬声器连接到机器。然后，您可以在Mac上播放音轨，然后在支持(Mac)蓝牙(Bluetooth)的扬声器 上收听。
许多Mac(Macs)还具有 3.5 毫米音频插孔，允许您插入有线耳机和耳机并将(wired earphones and headphones)其与您的机器一起使用。
但是，问题是您不能同时使用无线和有线耳机。如果您的两台设备都连接到您的Mac，您的Mac只会将输出发送到您的一台设备。另一台设备将没有声音，并且在您从机器中弹出第一台设备之前将保持不活动状态。
但是，如果您遵循以下解决方法，则无需移除其中一台设备。有一个巧妙的小技巧可以让您在Mac上同时使用包括耳机或扬声器的双扬声器。它不需要外部设备，您只需使用Mac(Mac)上的内置工具即可完成整个过程。
将双扬声器连接到 Mac(Connect Your Dual Speakers To Your Mac)
该过程的第一步是将有线和无线扬声器插入Mac。如果您是有线扬声器，请使用Mac上的 3.5 毫米端口进行连接。无线音箱可以通过蓝牙(Bluetooth)连接。
单击(Click)菜单栏中的蓝牙(Bluetooth)图标，在列表中选择您的音频设备，然后选择显示为Connect的选项。
你的两个扬声器现在都应该连接到你的Mac上了。
在 Mac 上创建多输出设备(Create a Multi-Output Device On Your Mac)
您现在需要做的是创建一个可以在Mac上进行两个输出的虚拟设备。然后，您将向此设备添加双扬声器，此设备将充当您机器的单个音频输出设备。
Mac上的内置应用程序应该可以帮助您完成工作，以下是您可以访问它的方法。
单击Dock 中的Launchpad ，选择(Launchpad)Other选项，然后找到并单击显示Audio MIDI Setup的应用程序。这就是你要使用的。
当应用程序启动时，单击左下角的+（加号），然后选择“创建多输出设备(Create Multi-Output Device)”选项。您将在此处创建您的虚拟设备。
在左侧边栏中单击(Click)您新创建的设备，在右侧窗格中您要同时使用的所有设备上打勾，然后为您的辅助扬声器打勾漂移校正(Drift Correction)框。
右键单击左侧边栏中的虚拟设备，然后选择Use This Device For Sound Output。
您的虚拟声音设备已成功创建。它现在已准备好接收音频作为输入，并将其流式传输到您连接的两个扬声器。
将虚拟设备设置为 Mac 上的主要声音输出(Set The Virtual Device As The Primary Sound Output On Mac)
您现在需要更改Mac上的设置，以便将机器播放的所有声音定向到虚拟设备(all the sound that your machine plays is directed to the virtual device)，然后虚拟设备将其进一步定向到双扬声器。
您可以在Mac的设置菜单中找到需要更改的选项。
单击(Click)屏幕左上角的Apple标志，然后选择(Apple)System Preferences。
在以下屏幕上，单击“声音(Sound)”选项以更改 Mac 的声音设置。
单击顶部的“输出”选项卡以查看当前连接到(Output)Mac的所有声音输出设备。在列表中选择您的虚拟声音设备，将其设置为整台机器的默认扬声器。
您无需手动保存设置，因为您的Mac会为您完成。
测试双扬声器设置(Test The Dual Speaker Setup)
由于您的虚拟设备现在是 Mac 的主要和默认扬声器，因此您Mac的(Mac)所有声音（包括系统声音）都将在虚拟设备上播放。您将在连接的多个扬声器上听到它们。
还应该注意的是，您将无法从 Mac 的音量控制菜单控制扬声器的音量。您需要使用应用程序中的选项来控制音量级别，或者您需要在扬声器本身上手动定义这些级别。
如何切换回默认系统(How To Switch Back To The Default System)
当您在多扬声器系统上听完您最喜爱的音乐曲目后，您可能想要回到默认的Mac扬声器。
此外，如果您不打算再次在Mac上使用多个扬声器，您可以从您的机器上移除虚拟设备。在这里，我们向您展示如何做到这两点。
使用默认 Mac 扬声器(Use Default Mac Speakers)
- 打开System Preferences面板并选择Sound，然后选择Output。
- 单击列表中显示“内部扬声器(Internal Speakers)”的设备。

删除虚拟声音设备(Remove Virtual Sound Device)
- 从Mac(Mac)上的Launchpad打开音频 MIDI 设置(Audio MIDI Setup)应用程序。
- 在列表中选择您的设备，然后单击底部的– （减号）按钮。(–)
它会立即从列表中删除该设备。
结论(Conclusion)
MacOS 让您同时在双扬声器上播放音乐的能力非常棒，因为您可以将一个扬声器放在您的房间，另一个放在另一个房间，两者都可以欣赏您的音乐曲目。
How to Use Dual Speakers on Mac
Most Mac machines come equipped with Bluetoоth enabling you to connеct yoυr external speakers to your mаchіne. You can then play a sоundtrack on your Mac to then listen to it on your Bluetooth-enabled speakers.
Many Macs also have the 3.5mm audio jack allowing you to plug in and use your wired earphones and headphones with your machine.
However, the problem is that you can’t use both wireless and wired headphones at the same time. If both your devices are connected to your Mac, your Mac will only send the output to one of your devices. The other device will get no sound and will remain inactive until you eject the first device from your machine.
You don’t need to remove one of the devices if you follow the following workaround, though. There’s a neat little trick that allows you to use dual speakers that include headphones or speakers at the same time on your Mac. It requires no external equipment and you can do the entire procedure using just the built-in tools on your Mac.
Connect Your Dual Speakers To Your Mac
The first step in the procedure is to plug in your wired and wireless speakers to your Mac. If yours is a wired speaker, use the 3.5mm port on your Mac for connection. Wireless speakers can be connected via Bluetooth.
Click on the Bluetooth icon in the menu bar, select your audio device in the list, and choose the option that says Connect.
Both your speakers should now be connected to your Mac.
Create a Multi-Output Device On Your Mac
What you now need to do is create a virtual device that can take two outputs on your Mac. You’ll then add dual speakers to this device and this device will act as a single audio output device for your machine.
A built-in app on your Mac should help you get the job done and the following is how you can access it.
Click on Launchpad in the Dock, select the Other option, and find and click on the app that says Audio MIDI Setup. This is what you’re going to use.
When the app launches, click on the + (plus) sign at the lower-left corner and select the option that says Create Multi-Output Device. You’ll create your virtual device here.
Click on your newly created device in the left sidebar, put a tick-mark in all the devices that you want to use at the same time in the right pane, and tick-mark the Drift Correction box for your secondary speaker.
Right-click on your virtual device in the left sidebar and choose Use This Device For Sound Output.
Your virtual sound device has been successfully created. It’s now ready to receive audio as an input and it’ll stream it to both your connected speakers.
Set The Virtual Device As The Primary Sound Output On Mac
You now need to change a setting on your Mac so that all the sound that your machine plays is directed to the virtual device which will then direct it further to your dual speakers.
You’ll find the option that needs changing in the settings menu on your Mac.
Click on the Apple logo at the top-left corner of your screen and select System Preferences.
On the following screen, click on the option that says Sound to change your Mac’s sound settings.
Click on the Output tab at the top to see all the sound output devices currently connected to your Mac. Select your virtual sound device in the list to set it as the default speaker for your entire machine.
You don’t need to manually save the settings as your Mac will do it for you.
Test The Dual Speaker Setup
Since your virtual device is now the main and default speaker for your Mac, all of your Mac’s sounds – including the system ones – will play on the virtual device. You’ll hear them on your connected multiple speakers.
It should also be noted that you won’t be able to control the volume of your speakers from your Mac’s volume control menu. You’ll need to use the options in your apps to control volume levels or you’ll need to manually define these levels on the speakers themselves.
How To Switch Back To The Default System
When you’ve finished listening to your favorite music tracks on your multi-speaker system, you may want to go back to the default Mac speakers.
Also, if you aren’t going to use multiple speakers with your Mac again, you can remove the virtual device from your machine. Here we show you how to do both.
Use Default Mac Speakers
- Open the System Preferences panel and choose Sound followed by Output.
- Click on the device that says Internal Speakers in the list.

Remove Virtual Sound Device
- Open the Audio MIDI Setup app from the Launchpad on your Mac.
- Select your device in the list and click on the – (minus) button at the bottom.
It’ll instantly remove the device from the list.
Conclusion
MacOS’ ability to let you play music on dual speakers at the same time is great as you can place one speaker in your room and the other one in another room, and both can enjoy your music tracks.
