Buzzer Frequently Asked Questions | Jialigao Electronics

Who is Jialigao (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.

How many years of experience does the company have?

The company has been operating since 2006, giving us more than 20 years of experience in electroacoustic product design and manufacturing.

Where are your production bases located? Can I visit the factory?

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.

Which industries do your products serve?

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.

What types of buzzers do you manufacture?

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.

What is the difference between electromagnetic, piezoelectric and SMD 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.

What specifications are available?

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.

Are your products standard or customizable?

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.

Do you support OEM/ODM customization?

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.

Which parameters can be customized?

We can adjust frequency, sound pressure (SPL), working voltage, size, mounting way and terminal structure. We also support custom voice prompts, warning alarms and special sound sources, as well as logo printing.

Can you customize the sound, voice or print our logo?

Yes. We support custom voice prompts, warning alarms and special sound sources, and can also print your logo on the buzzer to match your brand requirements.

What information should I provide to get a custom quote?

To help us respond quickly, please provide your target specifications where possible, such as operating voltage, frequency, sound pressure level, size and mounting type, together with your estimated quantity. If you are unsure, our engineers can recommend a suitable solution based on your application.

Do you provide samples before mass production?

Yes. We support prototype sample development before bulk orders. Samples allow you to verify sound, size, performance and fit before committing to mass production.

What quality certifications does your factory hold?

Our factory operates a complete quality management system and has obtained ISO9001 certification. Our products comply with RoHS and REACH standards to satisfy international market requirements.

How do you control quality during production?

Quality control runs through the whole process, covering raw material incoming inspection, production process monitoring and finished product testing. Every batch of goods is inspected before delivery, including pre-shipment inspection, to help reduce defective rates and after-sales risks.

What tests do your products pass?

Our buzzers undergo multi-round testing on sound pressure, frequency, working voltage, temperature resistance and stability/aging, so that each product performs reliably in your application.

Do you provide test reports or certificates?

Yes. We can provide relevant test results and certificates (such as ISO9001, RoHS and REACH compliance documentation) to support your market entry. Please request the specific documents you need when contacting us.

What is your minimum order quantity (MOQ)?

We offer flexible MOQ and support both small-batch and mass production, so we can accommodate projects at different stages. Please share your estimated quantity with our sales team for a specific MOQ arrangement.

What are the payment terms?

Payment terms are arranged based on the order size and the cooperation model. Our sales team will provide the applicable terms for your project when you request a quotation.

How do you deliver and what is the lead time?

We ship to customers worldwide, and lead time depends on the product type, customization level and order quantity. Samples are usually prepared first, followed by mass production. Please contact our team for the lead time applicable to your order.
