🚧 This site is a still a work in progress! 🚧
The Zeekr 7X is packed with cutting-edge tech, one of its features is the ability to load custom lock, unlock, and system sound effects via a USB drive. If you are tired of the standard factory chimes and want your SUV to stand out, you can completely personalise its audio profile.
However, automotive infotainment systems are notoriously picky about audio formats. In this guide I will show you how to create and use custom vehicle sounds.
Keep in mind that I have not yet been able to test this due to not having my Zeekr 7X arrive yet, this is based on information I’ve been able to find online.
If you do not have any audio files, you can use pre-made sounds from open Tesla libraries
Tesla sites have large librarys of sounds that are already in a compatible format and will work with your Zeekr 7X! This may save you time, however you will still need to setup the USB drive as below.
💻 Preparing the USB Drive
ZeekrOS is strict. If your USB drive isn’t configured exactly right, the car will not detect your custom files.
1. Partition Scheme & Formatting
Plug your USB drive into a computer and format it with the following settings:
- File System:
exFAT(Do not use NTFS or FAT32). - Partition Style:
GPT(GUID Partition Table).
2. The Exact Folder Structure
Zeekr’s operating system looks for a highly specific, hardcoded folder name at the root level of your drive.
- Open your newly formatted USB drive.
- Create a folder at the absolute root named exactly:
解闭锁音效(which translates to “Lock/Unlock Sound Effects”).
📂 Drive Path Example:
E:\解闭锁音效\
🎵 Mastering the Audio Files
The Zeekr 7X hardware expects raw, uncompressed audio. If you try to drop a standard MP3 or a high-res FLAC file into that folder, the car will ignore it.
Your audio files must meet these exact specifications:
- Format: Standard Uncompressed PCM WAV
- Bit Depth: 16-bit Le (
pcm_s16le) - Sampling Rate: 44.1 kHz (44,100 Hz) or 48 kHz
- Channels: Mono or Stereo
- File Size Limit: Strictly under 1.0 MB (Typically, keeping the audio clip under 3 to 5 seconds ensures it stays well under this limit).
You can use this link https://cloudconvert.com/mp3-to-wav to convert any file to the correct WAV format, just ensure that you match the specifications listed here.
Now that you have your audio files, you need to copy them into the folder structure that we created earlier. This is the folder named 解闭锁音效 in your USB drive.
Once these files are copied, you can remove the USB and head to the car.
🚗 Navigating the Zeekr 7X Screen
With your USB drive prepped and your 16-bit WAV files loaded, it’s time to configure your vehicle to use them.
- Plug in the USB: Locate the center console USB ports. Insert your drive into the data-capable port (usually the Type-A port or the designated media Type-C port, depending on your trim configuration).
- Wake up the Infotainment System: Power on the central 15.0-inch 2.5K OLED screen.
- Open Vehicle Settings: Tap the Car / Settings icon (located on the bottom dock or the main apps menu).
- Navigate to Sound Settings: Select Sound & Notifications (or 声音与提示 depending on your local language/firmware variant) from the left-hand menu sidebar.
- Locate Sound Effects: Scroll down to the Vehicle Sound Effects or Equalizer & Chimes section. Look for an option explicitly labeled Lock/Unlock Sound (
解闭锁音效). - Import from USB: If your folder structure and file formats are correct, a “Custom” or “USB Import” button will light up. Tap it to view your files, preview the sound, and hit Apply.
💡 Troubleshooting Quick Tips
- “No files found” error: Check your folder name. It must be the Chinese characters
解闭锁音效. Even a trailing space will cause the system to reject it. - File grayed out: Your file size is likely over 1MB, or the bit depth accidentally saved as 24-bit or 32-bit float instead of 16-bit PCM. Re-run it through your container to strip the excess data.
