So we decided to try out how much we could improve the sound quality by actually incorporating ceramic piezoelectric elements into mobile devices. However, at first, everyone was skeptical, wondering if it would really work that well.
However, when I actually tried talking using the prototype
I found that I could hear better than I expected.
The timing of starting development was also good. CEATEC 2011, Asia's largest comprehensive exhibition of cutting-edge IT and electronics, was about to begin. There, SSR was unveiled as a new sound technology at the KDDI booth.
The response was excellent, and the product also b2c datasets won the CEATEC AWARD that year. It began to dawn on them that "this is something the world needs." Otsuki and the rest of the development team felt that the response was even better than they had expected.
Two concerns about mass production
However, the real difficulties came later. "We are engineers, so we thought that as long as it produced sound, that was enough," Otsuki says, reflecting on his own naivety.

A prototype is just a prototype. No matter how good a prototype you can create, it is a kind of "master craftsmanship." When mass-producing hundreds of thousands or millions of units, can you really produce something of the same quality? Furthermore, when delivering a final product to consumers, it is not enough to convince them that it simply sounds good. There is such a thing as a pleasant sound.
From there, with the cooperation of KDDI
We worked to improve the sound quality. We tried changing the thickness of the ceramic, the number of layers, etc. In the end, we ended up stacking twice as many ceramic layers as originally planned. We repeated the process of stacking each layer and testing again and again. We adjusted the sound pressure and the flatness of the sound over and over again.
