Academic Gene

 String Bean™ — a brand of a Professor's Passionate Pursuit of Excellence in Physics and Music

When our founder's daughter first showed an interest in the violin at the age of three, he wanted to support her passion. He purchased a 1/10-sized violin for her, but was quickly disappointed with its lack of quality and subpar sound. He believed that professional musicians needed high-quality instruments to excel, and that mediocre instruments would never lead to success.

Determined to help his daughter, he poured his knowledge as a highly accomplished physicist into a comprehensive study of the violin family. Through his hard work and dedication, he discovered a solution - String Bean™ for strings.

Dr. Chyh-Hong Chern, our co-founder and inventor, has a Ph.D in theoretical physics from Stanford University and a distinguished career in academia. He left his tenured position at National Taiwan University to bring his latest invention to life.

When our founder's daughter tried the prototype for the first time, she was amazed at the transformation of her instrument. With the help of String Bean™, she quickly mastered the fundamentals of playing the violin. This inspired Dr. Chern to believe that no musician should be limited by their instrument.

At String Bean Ltd., we are dedicated to sharing the latest advancements in research and technology with young musicians everywhere. By resigning from his academic position, Dr. Chern has brought a new hope to the musical community. String Bean™ represents the next chapter in musical history, filled with happiness and limitless potential.
