If the speaker on your Apple Watch Series 9 is not working, produces distorted sound, or you can’t hear calls and notifications clearly, the issue is usually caused by a damaged or faulty speaker module.
In this step-by-step repair guide, you’ll learn how to replace the Apple Watch Series 9 speaker and restore clear audio performance without replacing the entire device.
🔧 Tools Required for Apple Watch Series 9 Speaker Repair
Before starting the repair, gather the following tools:
- Tri-Wing Y0.8mm screwdriver

⚠️ Signs Your Apple Watch Speaker Needs Replacement
You may need to replace the speaker if you notice:

A speaker replacement usually resolves these issues completely.
🔌 Step 1: Power Off the Watch

This softens adhesive and makes opening safer.
🪛 Step 3: Separate the Display
- Insert a thin blade or opening tool into the gap between the display and frame.

A damaged speaker is the main reason for sound problems in Apple Watch devices.
🔄 Step 8: Install the New Speaker

If sound is clear, continue with sealing the device.
💧 Step 11: Restore Water Resistance
