About Baacoustic
Baacoustic is the export brand of Inner Mongolia Enwo Electronics Technology Co., Ltd., a manufacturer of balanced armature receivers for hearing aids, earphones and smart wearables, offering OEM/ODM manufacturing to global brands.
Who We Are
Baacoustic is the export brand of Inner Mongolia Enwo Electronics Technology Co., Ltd., founded in 2019 and located in Hongshan Industrial Park, Chifeng, Inner Mongolia, China. The company has a registered capital of RMB 100 million, occupies a 130-mu campus, and is a governing-council member of the China Electronics Audio Industry Association.
We are focused on one thing: the research, production and sale of balanced armature receivers. Our products are used in hearing aids, high-end earphones, in-ear monitors and medical devices, and are shipped to OEM buyers in Europe, the Americas, Japan and Korea.
Our Facilities
Our phase-I campus includes 30,000 m² of production floors, a 1,800 m² core component workshop, a modern office and R&D building, a national-level acoustic testing laboratory (4,000 m²), an electro-acoustic product R&D center, and six production buildings with 100,000-class cleanrooms. Six balanced armature receiver production lines are currently in operation, supported by in-house automation for welding, magnetization testing and diaphragm forming.
Certifications & Honors
Recognized by the Chifeng Municipal Federation of Industry and Commerce as a top-10 science and technology private enterprise two years in a row, and a governing-council member of the China Electronics Audio Industry Association.
Engineering & Technology
Our R&D team is made up of senior acoustic specialists and engineers with an average of more than 10 years of balanced armature receiver development experience. We hold multiple core patents covering product design, manufacturing process and equipment development, including precision metal mold design and automated production lines that improve both precision and efficiency.
We cooperate with the Institute of Acoustics of the Chinese Academy of Sciences and leading university acoustics institutions on materials and simulation work, including magnetic-circuit simulation, vibration analysis and acoustic characteristic modeling for every new design.
In materials science, we work with leading domestic research institutions on high-performance magnetic and diaphragm materials, and we have adopted MEMS (micro-electromechanical systems) technology to further improve power efficiency and stability.
