大多数 iPhone 型号都是高性能产品。但是，与任何其他设备一样，它们也容易受到黑客攻击(susceptible to hacks)、故障和崩溃的影响。
这些问题之一是 iPhone 扬声器不工作时。但是，此问题的确切原因可能需要一些故障排除才能发现。
在本指南中，我们将列出导致 iPhone 扬声器无法正常工作的一些原因以及一些您可以尝试使其再次工作的修复。
是什么导致 iPhone 扬声器无法正常工作？(What Causes the iPhone Speaker Not Working Issue?)
许多事情都可能导致您的 iPhone 扬声器无法工作。在大多数情况下，您可能需要进行一些故障排除才能确定确切的原因。但是，有一些典型的与硬件和软件相关的原因，包括：
- 扬声器损坏或损坏
- iPhone卡在耳机模式
- 音量太低或静音已打开
- 请勿打扰功能已启用
- 软件故障
- 扬声器开口堵塞或脏污
- iPhone 正在通过另一台设备流式传输音频
如何修复 iPhone 扬声器不工作(How to Fix iPhone Speaker Not Working)
在我们进行具体修复之前，请尝试以下快速检查，以确保不是其他原因导致扬声器出现问题。
- 检查扬声器或接收器开口是否脏污或堵塞，并用干燥的软毛刷清洁。
- 将(Insert)耳机插入耳机插孔并快速将其拔出。
- 重新启动您的 iPhone 以解决任何软件故障。
- 移动iPhone 设置中的铃声(Ringers)和警报滑块并聆听声音。(Alerts)如果您听到声音，则扬声器工作。如果没有声音(no sound)，扬声器可能已损坏，可能需要维修。
- 检查音量。如果音量调得太低而听不见，请使用 iPhone 上的音量按钮进行调整。您也可以通过说“嘿 Siri，调高音量”来使用 Siri调高音量。(using Siri)
- 检查屏幕保护(screen protector)膜或薄膜是否覆盖了麦克风，因为这些也可能导致声音问题。
- 检查Ringer/Silent或静音(Mute)开关是否被推向 iPhone 的背面。如果是，并且您在开关旁边看到橙色，则表示您的设备已设置为静音模式。要启用声音，请将开关推向屏幕并检查扬声器是否再次工作。
- 检查应用程序的声音设置以获取设备上的通知。如果它们设置为None，请选择一种声音并检查扬声器是否正常工作。
- 如果您的 iPhone 上有第三方应用程序，请检查它们的声音设置，因为许多应用程序都带有单独的音乐、音量、环境音频和音效设置。
- 检查请勿打扰(Disturb)( DND ) 模式是否已打开并将其禁用。启用后，DND模式会使许多通知和声音静音。如果您没有听到任何声音，请打开“设置”(Settings) > “请勿打扰(Do Not Disturb)”并将其切换为“关闭”(Off)。
- 将iOS 更新(Update iOS)到最新版本。
1.禁用静音未知呼叫者开关(Disable Silence Unknown Callers Switch)
静音未知呼叫者(Silence Unknown Callers)功能可将来自未知号码的所有呼叫静音，以帮助您避免自动电话和垃圾电话。启用后，您将不会听到未保存在“通讯录(Contacts)”应用中的未知号码的来电。
要禁用该功能，请打开设置(Settings )>电话(Phone )，然后点击静音未知呼叫者(Silence Unknown Callers)开关以将其关闭。
2.禁用蓝牙(Disable Bluetooth)
启用蓝牙(Bluetooth)后，您的 iPhone 扬声器无法播放声音，因为您的设备正在向另一个启用蓝牙的扬声器(Bluetooth-enabled speaker)发送音频。在这种情况下，关闭蓝牙(Bluetooth)将断开与外部扬声器的连接并通过 iPhone 的扬声器播放音频。
您可以通过“设置”(Settings) > “蓝牙(Bluetooth)”关闭iPhone 上的蓝牙(Bluetooth)，然后将开关切换到“关闭”或点击(Off)控制中心(Control Center)中的蓝牙图标以禁用蓝牙。
3.断开与 AirPlay 设备的连接(Disconnect from AirPlay Devices)
如果您的 iPhone 正在通过AirPlay设备流式传输音频，则扬声器可能无法工作。如果是这种情况，断开与AirPlay设备的连接可能会解决问题。
- 打开控制中心(Control Center)并寻找AirPlay图标。如果图标为蓝色，则表示您的 iPhone 已连接到AirPlay设备。
- 点击关闭 AirPlay 镜像(Turn Off AirPlay Mirroring)以断开与任何AirPlay设备的连接并再次通过 iPhone 扬声器流式传输声音。
4.删除耳机模式(Remove Headphone Mode)
当您的 iPhone 卡在耳机模式(Headphone Mode)时，即使您没有连接耳机，您也可能会看到一条显示耳机音量的消息。在这种情况下，错误可能会导致您的设备即使未插入耳机也会向耳机发送音频。
您可以通过清洁耳机插孔、插入耳机并快速将其拔出来解决此问题。
5.重置 iPhone 设置(Reset iPhone Settings)
如果到目前为止您已经尝试了所有修复，但您的 iPhone 扬声器仍然无法工作，请尝试将所有 iPhone 设置（包括声音、网络和显示设置）重置为默认设置。
打开设置(Settings)>通用(General)>重置(Reset)>重置所有设置(Reset all settings)。
注意(Note)：重置您的所有 iPhone 设置不会抹掉您的媒体文件、信息和应用程序。

iPhone Speaker Not Working? 5 Fixes to Try
Most iPhone models are high-performing products. However, like any other device, they’re also susceptible to hacks, glitches and crashes.
One of these problems is when the iPhone speaker is not working. However, the precise cause of this problem may require some troubleshooting to uncover.
In this guide, we’ll list some of the causes of the iPhone speaker not working problem and some fixes you can try to get it working again.
What Causes the iPhone Speaker Not Working Issue?
Many things can potentially cause your iPhone speaker not to work. In most cases, you may have to troubleshoot a bit to establish the exact cause. However, there are some typical hardware and software-related causes including:
- Broken or damaged speaker
- iPhone is stuck in headphone mode
- Volume is too low or Mute is turned on
- Do not Disturb feature is enabled
- Software malfunction
- Blocked or dirty speaker opening
- iPhone is streaming audio through another device
How to Fix iPhone Speaker Not Working
Before we get into specific fixes, please try the following quick checks to make sure it’s not something else causing the problem with the speaker.
- Check if the speaker or receiver opening is dirty or blocked, and clean it with a dry, soft-bristled brush.
- Insert your headphones into the headphone jack and quickly pull them out.
- Restart your iPhone to resolve any software glitches.
- Move the Ringers and Alerts slider in your iPhone’s settings and listen out for a sound. If you hear a sound, the speaker works. If there’s no sound, the speaker may be damaged and might need service.
- Check the sound volume. If it’s turned down too low to hear, adjust it using the volume buttons on your iPhone. You can also turn up the volume using Siri by saying “Hey Siri, turn up the volume”.
- Check whether the screen protector or film is covering the microphone as these may also cause sound problems.
- Check if the Ringer/Silent or Mute switch is pushed toward the back of your iPhone. If it is and you see the color orange next to the switch, it means your device is set to silent mode. To enable sound, push the switch toward the screen and check if the speaker works again.
- Check the apps’ sound settings for notifications on your device. If they’re set to None, select a sound and check if the speaker is working.
- If you have third-party apps on your iPhone, check their sound settings as many apps come with separate settings for music, volume, ambient audio and sound effects.
- Check whether the Do Not Disturb (DND) mode is on and disable it. When enabled, DND mode silences many notifications and sounds. If you don’t hear any sound, open Settings > Do Not Disturb and toggle it to Off.
- Update iOS to the latest version.
1. Disable Silence Unknown Callers Switch
The Silence Unknown Callers feature silences all calls from unknown numbers to help you avoid robocalls and spam calls. When enabled, you won’t hear calls from unknown numbers that aren’t saved in the Contacts app.
To disable the feature, open Settings > Phone and tap the Silence Unknown Callers switch to toggle it off.
2. Disable Bluetooth
When Bluetooth is enabled, your iPhone speaker can’t play sounds because your device is sending audio to a different Bluetooth-enabled speaker. In this case, turning off Bluetooth will break the connection to the external speaker and play audio through your iPhone’s speaker.
You can turn off Bluetooth on iPhone via Settings > Bluetooth and toggle the switch to Off or tap the Bluetooth icon in Control Center to disable Bluetooth.
3. Disconnect from AirPlay Devices
If your iPhone is streaming audio through an AirPlay device, the speaker may not work. If that’s the case, disconnecting from AirPlay devices may fix the problem.
- Open Control Center and look for the AirPlay icon. If the icon is blue, it means that your iPhone is connected to an AirPlay device.
- Tap Turn Off AirPlay Mirroring to disconnect from any AirPlay device and stream sound through your iPhone speaker again.
4. Remove Headphone Mode
When your iPhone is stuck in Headphone Mode, you may see a message showing your headphone volume even though you’ve not connected your headphones. In such cases, a bug may be causing your device to send audio to the headphones even when they’re not plugged in.
You can resolve this by cleaning the headphone jack, plugging in your headphones, and quickly pulling them out.
5. Reset iPhone Settings
If you’ve tried all the fixes so far and your iPhone speaker still won’t work, try resetting all the iPhone settings including sound, network and display settings to default.
Open Settings > General > Reset > Reset all settings.
Note: Resetting all your iPhone settings doesn’t erase your media files, messages and apps.
iPhone Speaker Not Working? Next Steps
If none of these tips fixed the problem, you can factory reset your iPhone, get tech support from Apple online or make a Genius Bar appointment at your nearest Apple Store.
