Today, with the rapid iteration of smart electronic devices, every precise sound prompt and every safe alarm and warning cannot do without the support of core sound-emitting components. Jiangsu Huaneng Electronics Co., Ltd. has been deeply engaged in the research and development and production of buzzers for many years. With its strong technical strength, strict quality control, and rich product line, it has become a benchmark enterprise in the domestic piezoelectric active buzzer field. Its four main series products, HND-2310B, HND-2316, HND-4216, and HND-4310, with their advantages of stability, efficiency, and low power consumption, are widely applied in various household appliances and instrument equipment, safeguarding the safety and convenience of every scenario.
Since its establishment in 2013, Jiangsu Huaneng Electronics has been dedicated to the research and development and production of electromagnetic and piezoelectric buzzers. Relying on the industrial agglomeration advantages of Chenbo Industrial Park in Xinghua City, it has established a full-chain control system from raw material procurement to finished product inspection, with a monthly output of 12 million units and over 300 product specifications. With reliable quality, its products are exported to many countries and regions around the world, and it has established stable customer cooperation relationships in the fields of communication, household appliances, and automotive electronics. The company is equipped with a professional R&D team and fully automatic testing equipment, and adheres to technological innovation to meet market demands. Its piezoelectric active buzzer series products, with the convenient features of built-in oscillation circuits, no need for additional drive signals, and the ability to sound upon power-on, have become the preferred partners of home appliance and instrument manufacturers.
As the core and main series of Huaneng Electronics, the four piezoelectric active buzzer series, HND-2310B, HND-2316, HND-4216, and HND-4310, cover different size and performance requirements and are suitable for multiple application scenarios, each with its own focus but equally outstanding:
The HND-2310B series adopts a compact design, with a diameter of 23mm and a height of 10mm. The operating voltage ranges from 3V to 24V, with a power consumption as low as 5-20mA. The sound pressure is clear and moderate, suitable for small-sized household appliances and portable instruments. With its small size and stable performance, it is an ideal sound-emitting choice for small electronic devices.
The HND-2316 series optimizes the acoustic structure on the basis of the 23mm diameter specification, significantly enhancing the sound pressure intensity. The sound is soft and has strong penetration, balancing practicality and comfort, and is widely used in various household instrument prompt scenarios.
The HND-4216 series has a diameter of 42mm and a height of 16mm, with an operating voltage range of 9V to 50V. Some models have a sound pressure of up to 95dB, with excellent high-temperature resistance and anti-interference capabilities, suitable for industrial-grade instruments and large household appliances, and can stably sound in complex environments.
The HND-4310 series combines high performance and durability, optimizing the resonant frequency design to focus on the 2-4kHz range sensitive to the human ear, with a response speed faster than 10 milliseconds. It is suitable for precision instruments and smart home appliances with high requirements for sound accuracy, providing precise and timely sound feedback for the equipment.
As an electronic device that generates sound through the piezoelectric effect, the core component of a piezoelectric active buzzer is a piezoelectric ceramic plate. It generates mechanical vibration through the inverse piezoelectric effect, and the sound is amplified through the resonant cavity. It has significant advantages such as low power consumption, long lifespan (over 100,000 hours), and strong weather resistance (-20°C to 70°C stable operation). Compared with electromagnetic buzzers, it has a simpler and more compact structure and better electromagnetic compatibility. Its application scenarios are widespread in life and industry, especially in various household appliances and instruments, playing an indispensable role as a "sound sentry". In the field of household appliances, piezoelectric active buzzers are ubiquitous: from the completion alerts of washing machines, the end-of-heating reminders of microwave ovens, the startup and fault alarms of air conditioners, the door-open and temperature anomaly alerts of refrigerators, to the cooking completion alerts of rice cookers, and the successful unlocking and fault alerts of smart locks, etc. In these daily scenarios, the HND series buzzers from Huanele provide clear sounds, allowing users to promptly understand the operational status of the devices and enhance the user experience.
In the realm of instrument and equipment, their application is equally extensive and crucial: from the alarm alerts of medical monitors and the completion alerts of intravenous infusion in medical devices, to the fault alarms and production completion alerts in industrial control equipment, the parameter anomaly warnings in electronic meters, the low battery and fault alerts in smart water and electricity meters, and the intrusion alerts and smoke alarms in security devices, etc. The HND series piezoelectric active buzzers from Huanele, with their stable performance, offer reliable sound feedback for these precision devices, ensuring their normal operation and usage safety.
From convenient alerts in household settings to safety guardians in industrial and medical fields, Jiangsu Huanele Electronics has always been committed to quality as the foundation and technology as the core. With the HND-2310B, HND-2316, HND-4216, and HND-4310 four series of piezoelectric active buzzers, it injects "clear sounds" into various devices. In the future, Huanele Electronics will continue to focus on research and development, optimize product performance, and improve the product line, providing better products and services to empower more industries to upgrade, and safeguarding every bit of peace of mind and convenience with professional sound-emitting devices .
