On March 28, 2020, Shenzhen sound industry association, together with acoustic building forum and online and offline training institutions, held the third activity of online public electroacoustic technology lecture series training through "Tencent conference app" online conference and live broadcast. Du Gonghuan, a doctoral director of Nanjing University, gave a lecture on "the importance of acoustic foundation to electroacoustic design and application".
China electronic audio industry association, audio and video technology branch of China acting association, engineers' Union, Shenzhen engineers' Union, Guangzhou electronic audio industry association, acoustic building forum and audio and video industry tycoons gave strong support and help to this public audio technology lecture. Engineers, elites and celebrities from all over the country (more than 280 people) attended the live broadcast of this Saturday's electroacoustic technology public lecture course. Mr. Wang Xichu, Deputy Secretary General of Shenzhen sound industry association, presided over this public welfare training activity.
About the speaker:
Professor Du Gonghuan is a doctoral supervisor of Nanjing University. He graduated from the Department of physics of Nanjing University in 1957 and has been teaching in Nanjing University until now. In 1993, he obtained the qualification of doctoral supervisor of the academic degree committee of the State Council. He has visited the University of Tennessee, the University of Vermont and the National Center for physical acoustics (NCPA) for many times. More than 100 papers have been published, of which more than 30 are included in SCI. He is the author of the book acoustic foundation, 460000 words, which was republished in 2012 (the Third Edition).
In this lecture, Mr. Du emphasized the importance of acoustic foundation for the design and application of electroacoustic devices. The vibration structure, sound radiation, sound pressure and acceleration curve of piston vibration in the cavity, vibration velocity curve, vibration displacement curve and total quality coefficient of T / S parameters are described respectively. In the lecture, combined with many years of research work experience, I devoted a lot of efforts to teach you the key knowledge points of acoustic foundation and how to analyze different product types.

China's audio industry has been greatly affected by the epidemic, especially the small and medium-sized enterprises are facing the choice of returning to work and production. At the initiative of Shenzhen audio industry association, in order to fight against "epidemic", support enterprises to overcome difficulties together and ensure stable economic growth of enterprises. When we were honored to invite Mr. Du, he said it was incumbent on us to attach great importance to this lecture, and carefully prepared the lecture for everyone's selfless dedication. At the age of more than 80, he was still the first to attend the first conference lecture in the field of Chinese acoustics. We sincerely appreciate his "teacher's morality Yongming". His spirit inspires us to overcome the difficulties, help each other, and continue to strive for the early and resolute win of the "epidemic" situation prevention and control resistance war. "Those who have the same aspirations will not be far away from mountains and seas.". At the same time, I would like to thank everyone who escorts my dream. We use technology, energy and strength to write perfect answers.
Under the guidance and concern of China electronic audio industry association and Shenzhen audio industry association, In the past 15 years, the acoustic building forum has provided a platform for engineers in the electroacoustic industry to communicate with each other and learn from each other. It also provides a window for suppliers and suppliers in the electroacoustic industry in China to communicate with each other and plays a positive and important role in improving professional skills and working standards of personnel in the audio industry, especially in the electroacoustic industry.
Next weekend (2:00 p.m. on April 4), we will invite Mr. Wang Yongming, an expert of Shenzhen sound industry association, MBA of Renmin University of China and chief Acoustic Engineer of Harman international, to share how to develop a good earphone in the fourth public electroacoustic technology lecture series, which is wonderful! Please pay attention to the announcement of WeChat official account of "acoustic tower forum" and "Shenzhen audio industry association".
