Recently, Youdao Dictionary Pen X6 Pro, a superb new-generation tutoring tool, has been released. This talking pen uses AAC’s integrated acoustic solutions: a BoomBox high-volume speaker that features an integrated acoustic tuning algorithms and expert tuning by Golden Ear experts. The solution delivers a crystal-clear and pleasant sound for an immersive listening experience to help children improve their learning effectiveness and ability.
At a press conference, according to Mr. Wu Yinghui, Senior Vice President of NetEase Youdao and Head of Intelligent Hardware, sound quality is a common concern for users. Youdao and AAC jointly developed a loudspeaker with brand-new material and structure for the Youdao Dictionary Pen X6 Pro. With joint calibration by Golden Ear experts for the first time, a talking pen with top-level sound quality that rivals flagship smartphones and speakers has been customized for Youdao.
AAC’s High-Volume Speaker – BoomBox Is Loud and Clear, Greatly Improving Children’s Learning Experience
A good speaker must be able to reproduce accurate and clear pronunciation along with high sound quality. BoomBox used for Youdao Dictionary Pen X6 Pro is a high-volume speaker with top-level performance for talking pen products. With AAC’s proprietary Super-Linear technology, BoomBox boasts a high excursion of 0.5 mm and brings a 100% increase in volume. Even in noisy environments, it enables the talking pen to speak clearly. Therefore, children can easily talk with teachers, accurately master pronunciation skills, and improve learning efficiency.
△BoomBox is designed with an all-metal structure, five magnetic circuits and a double-diaphragm skeleton
According to the frequency response tests in AAC Acoustics Laboratory, BoomBox features an obvious increase in low-frequency flexibility and extensibility. It produces a fuller bass sound and stronger rhythm, as well as a wide intermediate frequency range. This enables clear and natural voices and a rich and detailed listening experience. Furthermore, BoomBox can produce crystal-clear and detailed highs at 16 kHz.
Algorithm tuning integration + Golden Ear expert tuning to deliver a top-level listening experience
In addition to hardware, Youdao Dictionary Pen X6 Pro shines with an AAC’s integrated acoustic tuning algorithms, which further improves the loudness and fidelity of sound and reduces distortion and noise at the algorithm level. Children can listen to stories and learn songs on the go while X6 Pro produces vivid and full voices, as if a real person was talking. This level of sound quality delivers a fully immersive auditory experience.
X6 Pro uses AAC’s integrated acoustic tuning algorithms:
- Frequency response correction with an equalizer: Optimize the frequency response to improve tonal balance and sound fidelit
- Dynamic Range Control: Improve sound dynamics, retain original sound characteristics, and enhance the impact of sound
- Limiter protection: Control signal amplitude to prevent high-frequency distortion
- Airflow Noise Suppression: Reduce noise caused by airflow, and reduce the difficulty of designing the front cavity of the speaker
- Virtual Bass enhancement: Enhance low frequencies based on psychoacoustic model
- Transient Distortion Correction: Enhance sound dynamics to improve fidelity
In addition, AAC has offered Golden Ear expert tuning services for Youdao Dictionary Pen X6 Pro. AAC has a professional assessment team with Golden Ear certification, and can conduct full assessment and tuning of the X6 Pro audio system in specific scenarios to maximize the sound quality of X6 Pro.
