If your electric lighter makes a high-pitch buzzing sound when you press the ignition switch, that sound is usually normal.
In most cases, the noise comes from the high-voltage system that creates the plasma arc. The arc itself produces a small sound wave, so what you hear is part of the lighter working as designed.

Why the Sound Happens
An electric arc lighter does not use butane or a visible flame. Instead, it generates a concentrated electrical arc between the electrodes. That process can create a light buzzing or high-frequency sound during ignition.
For many users, the first reaction is to wonder whether something is wrong. In general, a brief high-pitch sound during use is not a danger sign by itself.
Why Pets May React to It
Pets can be more sensitive to unfamiliar sounds than people. A dog or cat may feel cautious the first time they hear the lighter because it is new and unexpected.
After hearing it once or twice without anything negative happening, many pets stop reacting strongly because they learn that the sound does not signal a threat.
When the Sound Is Normal
- A short buzzing or high-pitch sound only while the ignition is active
- The lighter still creates a stable arc and works normally
- No burnt smell, overheating, or visible damage
When to Stop Using It
If the lighter makes unusual noise without producing an arc, becomes hot quickly, or shows visible damage, stop using it and inspect the product before trying again.
Final Takeaway
A high-pitch sound from an electric lighter is usually just the normal sound of the plasma arc system working. For people and pets, the unfamiliar sound may seem strange at first, but in normal use it is not a reason for alarm.
