About JLG

Jialigao (JLG) is a professional manufacturer of electroacoustic products, established in 2006. We specialize in the R&D and production of buzzers and related sound products, and are committed to providing reliable acoustic solutions for global customers. Our product lines cover electromagnetic (magnetic) buzzers, piezoelectric buzzers, SMD buzzers, as well as non-standard series such as voice and sound-source alarms.

The company has been operating since 2006, giving us more than 10 years of experience in electroacoustic product design and manufacturing.

We operate an independent R&D and production base of nearly 7,000 square meters in Jiangsu and Foshan, Guangdong, with nearly 1,000 units of equipment in production and over 100 skilled employees serving customers worldwide. Factory visits are welcome — please contact our sales team to arrange a tour.

Our buzzers are widely used across multiple industries, including security and fire alarm systems, home appliances, industrial control, automotive, medical devices, and IoT & smart devices.

We manufacture five main product categories: SMD buzzers (compact size, suited for automated SMT assembly), magnetic buzzers (stable performance, wide voltage range), piezo buzzers (low power consumption, clear and crisp sound), transducer / alarm buzzers (high sound pressure, various mounting options), and customized buzzers.

Electromagnetic (magnetic) buzzers generally offer a wide operating voltage range and stable performance. Piezoelectric buzzers typically consume less power and produce a clear, crisp sound. SMD (surface-mount) buzzers are compact in size and designed for automated SMT assembly, making them ideal for space-constrained or high-volume production. Our sales engineers can help you choose the best type for your application.

We offer a wide range of standard specifications. Typical options include working voltages such as 3V and 5V and up to 12V or higher, frequencies from about 2 kHz to 25 kHz, and sound pressure levels (SPL) from roughly 70 dB to 112 dB. You can browse our product catalog or contact us for the exact parameter range that fits your project.

We supply both standard catalog products and fully customized buzzers. If your project requires a specific voltage, frequency, SPL, size or appearance, our R&D team can tailor a solution for you.

Yes. We provide one-stop customization services for electromagnetic, piezoelectric and SMD buzzers, covering both modified standard products and fully non-standard electroacoustic solutions. Our experienced R&D team will cooperate closely with your engineering team from prototype sample testing through to mass production.
