"Currently, our technology can achieve over 80dB," Wang An explained. "The main causes of noise are mechanical parts, AC noise, and so on."
Because speakers are connected to mechanical amplifiers, they inevitably generate noise during operation, such as thermal noise, mechanical noise, AC noise, etc.
Seeing that Xiang Peisi was very professional in this area, Wang An directly unscrewed the back panel of the speaker, and the entire speaker was placed on the table, with all the internal components clearly visible.
"We experimented with many different combinations of speaker components before finally finding the most suitable ones. We added a dedicated subwoofer channel to the signal processing components, which can simulate AC-3 Dolby surround sound."
Wang An's eyes lit up when he talked about simulated surround sound.
In 1991, Dolby developed a new generation of Dolby Digital Surround Sound, ushering in a new era. Dolby products feature six completely independent channels and full-range surround sound.
When developing the speaker, Wang An always wanted to achieve this effect, but because the concepts of integrated circuit speakers and digital speakers were contradictory, he could only try his best to make a simulated effect with limited technology.
This is also one of his regrets.
In his view, even though the iPod achieved the number one sales position in Europe and the Americas, Chen Dong remained clear-headed and required the technology department to learn from Sony's technology department and constantly break through its own limitations.
"In the short term, the technology in China cannot break through the blockade imposed by Europe and the United States, so I do not intend to compete with Sony in the same field," Chen Dong said.
This idea aligns well with Xiang Peisi's, who asked: "For home speaker systems, what should the market focus on in the future? Which target group?"
“Since the 1990s, a retro trend has swept through the fashion industry, and now this trend has reached the field of audio amplifiers,” Chen Dong said. “In fact, the integrated circuit speakers we are developing now are precisely to cater to this trend.”
"In other words, our target audience is still the middle-aged people who were once enthusiastic about integrated circuits and vacuum tube speakers, as well as the young people who are now chasing the retro trend."
This topic reminded Xiang Peisi of his youth.
There are five types of audio amplifier manufacturing processes: vacuum tube, transistor, integrated circuit, field-effect transistor, and digital audio. Among them, vacuum tube audio is favored by audiophiles for its mellow tone and wide frequency response.
