What Our Customers Say

Lead Designer, Smart Ring Company:"Finding a buzzer under 2mm that actually works was our biggest hurdle. Shenghui's 1.8mm micro piezo buzzer was a game-changer. The 65dB output is perfect for a wearable, and their team understood our thinness challenge intimately."

Procurement Specialist, Medical Device Startup:"For our disposable sensor patch, component thickness and cost were everything. This 3V piezo buzzer from Shenghui hit the target on both. As a piezo buzzer manufacturer, they provided all the necessary compliance documentation, which streamlined our certification process."

Hardware Engineer, IoT Tag Developer:"We needed a reliable, low-power alert for a credit-card-sized tracker. This micro piezo buzzer with its 3V operation was ideal. Shenghui delivered samples quickly, and the performance was exactly as specified in the datasheet, proving their reliability as a piezo buzzer manufacturer."

Frequently Asked Questions (FAQ)

Q1: Why is the sound pressure level 65dB? Is that loud enough?

A: A 65dB output is intentionally designed for "personal" or "close-proximity" alerts. It is clearly audible to the user (similar to a normal conversation) without being disruptive to others nearby. This makes the 3V piezo buzzer perfect for wearables, smart home sensors in quiet rooms, or devices where a gentle, private notification is desired, as opposed to a loud, public alarm.

Q2: How do I drive this passive piezo buzzer, and what is the typical current draw?

A: This is a Passive Piezo Buzzer. It requires an external drive circuit providing a square wave at 4KHz with a 3Vp-p amplitude. A simple transistor switch controlled by a microcontroller is standard. The current draw is very low, typically in the range of a few milliamps, which is a key advantage of piezo technology and makes this 3V piezo buzzer highly efficient.

Q3: Can you provide even thinner piezo buzzers, or customize the sound frequency?

A: Yes, customization is a core strength of Shenghui Electronic as a leading piezo buzzer manufacturer. We are constantly pushing the limits of miniaturization. While 1.8mm is already extremely thin, we can discuss the feasibility of specific dimensions for your project. Similarly, we can adjust the resonant frequency, sound level, or other parameters of this micro piezo buzzer platform to meet your application's specific acoustic profile needs.
