Customer Questions & Answers
-
Question:
What are Prewired 35mm Piezo Discs used for?
Answer: Prewired 35mm Piezo Discs are versatile components primarily used for sound generation, vibration sensing, and pressure detection in various electronic applications. They can be utilized in projects like alarms, musical instruments, and DIY electronics, making them popular among hobbyists and professionals alike. By applying a voltage, they can produce sound or respond to mechanical stress, ideal for creating buzzer alarms or touch sensors. -
Question:
How do I connect the Prewired 35mm Piezo Discs?
Answer: Connecting Prewired 35mm Piezo Discs is straightforward. Each disc comes with pre-attached wires, typically red for positive and black for negative. You can connect the positive lead to a voltage source and the negative lead to the ground to enable sound production. This design allows for easy integration into microcontroller circuits, such as Arduino projects, enhancing their functionality in sound and vibration applications. -
Question:
What is the sound output of a 35mm Piezo Disc?
Answer: The sound output of a 35mm Piezo Disc varies based on the applied voltage and frequency. Generally, they can produce a loud sound, often exceeding 85 dB at close range. Their frequency response is broad, allowing them to generate different tones, making them ideal for alarms or notification sounds in electronic devices. Experimenting with different inputs can yield unique sounds for various applications. -
Question:
Are these discs suitable for beginners?
Answer: Absolutely! Prewired 35mm Piezo Discs are beginner-friendly due to their simple wiring and versatile applications. They can be easily integrated into basic circuits for sound projects, making them perfect for educational purposes or entry-level electronics kits. Whether for a school project or a personal hobby, they offer a hands-on way to learn about sound engineering and electronics. -
Question:
Can multiple discs be used in a single project?
Answer: Yes, multiple 35mm Piezo Discs can be used in a single project. By wiring them in parallel or series, you can create more complex sound patterns or enhance the volume output. This method allows for creative designs in projects such as musical instruments, alarms, or sound effects in installations. They provide flexibility in crafting immersive audio experiences. -
Question:
What materials are the Piezo Discs made of?
Answer: Piezo Discs are typically composed of ceramic materials, which are crucial for their ability to convert electrical energy into mechanical vibrations. The ceramic is often coated with a conductive material allowing for electric connections. This construction not only ensures durability but also efficient sound generation, making them reliable components in both hobbyist and professional electronics. -
Question:
Can I use these discs outdoors?
Answer: While Prewired 35mm Piezo Discs can be used outdoors, it's essential to protect them from moisture and extreme weather conditions. Encasing them in a waterproof enclosure can enhance their durability and ensure uninterrupted performance for outdoor projects, such as garden alarms or acoustic setups. With proper precautions, they can function well in a variety of outdoor environments. -
Question:
What voltage do these discs operate at?
Answer: Prewired 35mm Piezo Discs typically operate effectively in a voltage range between 3V to 12V. Operating within this range ensures optimal performance without damaging the components. It is important to check the specifications provided for your specific project to ensure that the voltage aligns with your desired output and conditions, maximizing their sound generation capabilities. -
Question:
How can I troubleshoot if my Piezo Disc is not working?
Answer: If your Prewired 35mm Piezo Disc isn't functioning, check the connections to ensure they are secure and correctly wired to the power source. Use a multimeter to test the voltage reaching the disc, and verify that it's within the operational range. Additionally, testing the disc with a different circuit or power supply can help isolate the problem, ensuring it functions as intended. -
Question:

Goedrum Triggers Editorial Review
The Goedrum Pack of 5 Prewired 35mm Piezo Disc is highly recommended for those looking to make their own drum pads or triggers. Customers have used them for replacing piezos in electronic drum sets, making custom pads, connecting to speakers, and creating a custom cymbal. The wire thickness is good, and the soldering is reliable. However, it is important to clarify the loading conditions before using the piezos. The product itself does not come with a data sheet, but a link to one can be found online. The piezos output an analog voltage, and the harder they are hit, the larger voltage deflections they will have. The wires are labeled LL85694 CSA TYPE AWM I A/B 80 Celsius FT1 2X0.325mm (22AWG) 300V WU-LI L.E. The only downside mentioned is that the adhesive rings that come with the product may make the triggers too responsive. Overall, this product is a great option for those looking to create their own electronic drum set or customize their existing one.
