如何播放日历提醒的默认和弦（Chord (default)）音效？

Hey there! I totally get it—you’ve tracked down classic sound IDs, but what you really want is that specific default Chord tone used for calendar reminders. Let’s walk through how to trigger it depending on your operating system:

Windows #

• Quick manual play (PowerShell): The default calendar reminder Chord is tied to Windows’ system "Exclamation" sound. Pop open PowerShell and run this command:

  [System.Media.SystemSounds]::Exclamation.Play()
  

• Command line alternative: You can also use the old-school rundll32 command:

  rundll32 user32.dll,MessageBeep 0x00000030
  

• To confirm it’s the right sound: Head to Control Panel → Sounds → Sounds tab, then look for "Calendar Reminders" under Program Events—it should list "Chord" as the assigned sound.

macOS #

• Command line play: macOS stores the Chord sound file directly in the system sounds folder. Open Terminal and run:

  afplay /System/Library/Sounds/Chord.aiff
  

• Swift code example: If you’re building an app, use AVFoundation to play it programmatically:

  import AVFoundation
  import AudioToolbox
  
  func playCalendarChordSound() {
      guard let soundURL = URL(fileURLWithPath: "/System/Library/Sounds/Chord.aiff") else { return }
      var soundID: SystemSoundID = 0
      AudioServicesCreateSystemSoundID(soundURL as CFURL, &soundID)
      AudioServicesPlaySystemSound(soundID)
  }
  

Linux (GNOME Desktop) #

• Most GNOME-based distros keep the default calendar chord alert here. Use paplay (PulseAudio’s player) to play it:

  paplay /usr/share/sounds/gnome/default/alerts/chord.ogg
  

Python Quick Scripts #

• Windows: Use the built-in winsound module:

  import winsound
  # Triggers the same Chord sound as calendar reminders
  winsound.MessageBeep(winsound.MB_ICONEXCLAMATION)
  

• macOS: Call the system’s afplay via subprocess:

  import subprocess
  subprocess.run(["afplay", "/System/Library/Sounds/Chord.aiff"], check=True)
