R&D

Technical R&D Mr Feng Microphone Professioner 1.Graduated from National Taiwan University of Science and Technology in 1994 2.Joined KNOWLES in 2002 as a microphone designer, leading the design of microphones. 3.Since 2017, he has served as the general manager of a Suzhou electroacoustic company, and FHD Electronic Acoustic Consultant. 4. Mr. Feng has nearly 30 years of industry experience in microphone design and MENS speaker design, and unique design understanding. Relying on Mr. Feng's technical and experience support, and KNOWLES's expertise in the field of microphones, our company introduced the 40/60 microphone production line in 2023 and started the road of microphone category design and manufacturing. SPECIALIZING IN ACOUSTIC TECHNOLOGY

Technical R&D Mr Cao Ultrasonic and Ceramic Professioner 1. PhD degree from Pennsylvania State University, USA Professor, PhD supervisor, Acoustic Functional Materials, Nanjing University 2.Our company has signed cooperation agreements with the institute of Acoustics and Materials in Nanjing University. 3.Professor Cao, as a specially-appointed foreign expert of Nanjing University and a consultant of FHD Electronic, has continuously provided our company with outputs in ultrasonic applications, piezoelectric ceramic formula design, and acoustics. 4.The main research direction is ferroelectric materials and their applications: including Landau- Ginzburg theory modeling, structural phase transition and domain structure, the relationship between material microstructure and physical properties; preparation and performance optimization of piezoelectric ceramics, textured lead-free piezoelectric ceramics and piezoelectric single crystals; characterization of full matrix material parameters (including elastic modulus, dielectric parameter matrix and piezoelectric parameter matrix) and high-precision autonomous material parameter array testing methods. SPECIALIZING IN ACOUSTIC TECHNOLOGY

Technical R&D Mr Zhang Ceramic Engineer 1.The developed pzt4 series of materials have been successfully applied to a certain military product project and have been mass-produced. 2.Mr. Zhang has 8 material formulas and R&D experience in the piezoelectric ceramic P4, P5, and P8 series, and has developed multilayer piezoelectric ceramic materials for low-temperature firing. 3.The developed material can be turned into porcelain at 900°C and can be co-fired with all-silver electrodes. This greatly reduces the production cost of multilayer piezoelectric ceramics. This series of materials has high kp and high piezoelectric coefficient. 4.It is suitable for the production of multi-layer piezoelectric ceramic speakers, piezoelectric feedback, and piezoelectric stacks. The ceramic products developed are used in many fields such as ultrasonic sensors, atomizers, displacement brakes, alarms, welding, and cleaning transducers. We have rich experience in the application of piezoelectric ceramics. SPECIALIZING IN ACOUSTIC TECHNOLOGY
