The global buzzer industry is undergoing a significant structural reshuffle. In recent years, many internationally leading manufacturers including Murata have successively suspended production, scaled down capacity or completely withdrawn from the buzzer business. Driven by strategic adjustments, rising comprehensive costs and industrial iteration, the industry is facing a substantial supply shortage, leaving numerous downstream customers confronting supply chain restructuring and potential supply disruption risks. Against this backdrop, Jiangsu Huaneng Electronics Co., Ltd. has emerged as a core domestic supplier and a benchmark for import substitution, filling the market gap with years of technical accumulation, stable large-scale production capacity and rigorous quality control systems.
As a national high-tech enterprise and provincial specialized and sophisticated enterprise, Jiangsu Huaneng has focused on the R&D, production and sales of piezoelectric and electromagnetic buzzers since its establishment in 2013. The company owns modern production workshops covering 20,000 square meters and 14 automated production lines, holding more than 50 technical patents. Its full-range product portfolio includes SMD buzzers, active and passive buzzers, and automotive-grade buzzers, which are widely applied in communication equipment, smart home appliances, new energy vehicles, industrial control systems and UPS power supplies.
Benefiting from its three core competitive advantages, Huaneng has rapidly taken over the market share vacated by exiting international manufacturers and effectively stabilized the industrial supply chain.
First, the company delivers industry-leading technical performance. Its buzzer products fully match international premium standards, with an operating temperature range from -40℃ to +85℃ and a maximum sound pressure level of 88dB. The resonance frequency deviation is controlled within ±300Hz, exceeding national industrial standards. Certified with IATF16949 automotive quality management system, Huaneng maintains a product defect rate below 50PPM, making its products the optimal alternative to imported buzzers for global downstream clients.
Second, large-scale and reliable production capacity ensures stable delivery. In 2025, the company’s annual buzzer shipment exceeded 310 million units, with the revenue of active buzzers reaching 428 million RMB, a year-on-year increase of 19.7%. With an annual production capacity of 500 million units, Huaneng has long-term stable cooperative relationships with well-known brands including Huawei, DJI and Xiaomi Eco-chain, capable of responding efficiently to bulk orders and urgent supplementary demands.
Third, customized solutions empower diversified industrial scenarios. Huaneng provides one-stop customized services covering product design, process development and mass production. It has developed ultra-low temperature resistant lightweight buzzers for DJI that pass strict -40℃ environmental tests, and ultra-miniature 3.8×3.8×1.4mm SMD buzzers for smart locks with a yield rate of 99.82%, occupying 34.6% of the domestic smart lock supporting market share.
Industry statistics show that the global buzzer market scale reached 1.45 billion US dollars in 2025 and is expected to grow to 2.18 billion US dollars by 2032, with a CAGR of 6.0%. Fueled by booming demand from new energy vehicles, smart homes and industrial IoT, the domestic substitution era for buzzer products has arrived, following the withdrawal of international leading manufacturers.
Jiangsu Huaneng Electronics has become a stabilizer and growth driver of the industry, promoting the high-end, localized and customized upgrading of the global acoustic component sector.
Company officials stated that the withdrawal of overseas leading manufacturers is both a challenge and a valuable opportunity for domestic enterprises. Moving forward, Jiangsu Huaneng will continuously increase R&D investment, optimize production capacity layout and upgrade comprehensive service capabilities. The company will continue to provide high-quality products and stable supply chain guarantees for global partners, striving to build a world-class national brand in the acoustic component industry.
