상품 특징

• Product packing: 2 electronic buzzers
• The product is made of PPO material.
• Safety: The electronic buzzer will emit a loud tone when it is powered. The sound is like a car alarm. The sound above the engine can be heard from several feet away.
• Work normally within the rated voltage range. If you think it is best to have a lower sound, there are a few ways. First, add a little bit of one or two resistors to reduce the sound level. Second, use a simple piece of electrical strip to cover all or part of the outlets. Third, wrap the buzzer in a paper towel and duct tape.
• The buzzer can be replaced with an old alarm clock as a piezoelectric speaker. Use these buzzers to extend the alarm to all levels of the house. As an alternative to piezo motorcycle horns. Use these buzzers to spin the signal alert on your motorcycle.
