Privacy protection shells have become common accessories for smartphones, laptops, and other devices. Their core principle is to limit the angle of light emission through a micro-visor structure, making the screen content clearly visible only when viewed

In today's rapidly developing smart voice devices, the AI ​​voice recorder has evolved from a simple recording tool into a highly efficient productivity terminal integrating acquisition, processing, transcription, and intelligent analysis.

In today's world where smart devices are ubiquitous, voice recorders, miniature cameras, and even everyday electronic products with recording capabilities bring convenience to work and life, but also quietly sow the seeds of privacy leaks.

In this information-saturated age, sound carries the key points of meetings, flashes of inspiration, classroom lectures, interviews, and even everyday notes.

The development of bio-based biodegradable materials has provided a new direction for environmental protection needs. These materials can reduce the environmental burden after long-term use while maintaining performance.

The signal delay during the noise reduction process needs to be controlled within milliseconds to avoid audio and video synchronization issues, which poses a dual challenge to both the hardware's transmission rate and the algorithm's efficiency.
