How to Hide Speakers in your Haunt or Halloween Display

What this video covers

This short tutorial from VanOaksProps demonstrates how to turn any flat prop surface into a hidden speaker using an audio exciter — no visible speaker cabinet required. Using a foam tombstone as the example, the build shows how an exciter unit is glued directly to the prop, allowing the surface itself to vibrate and produce sound. The setup requires a small amplifier and audio source connected to the exciter via speaker wire. It's a clever, low-cost solution for adding invisible ambient audio to a haunt or yard display.

Key takeaways

• ◆An audio exciter converts any flat or hollow surface into a functioning speaker by vibrating the material itself
• ◆A foam tombstone is used as the demo prop, but the technique works on many haunt surfaces
• ◆Hot glue (including black cosplay glue for a cleaner finish) is used to mount the exciter securely
• ◆A small external amplifier and audio source are required to drive the exciter
• ◆This approach keeps speakers completely hidden, preserving the visual immersion of your display
