Profiles of participating units
Juxin Technology Co., Ltd. (hereinafter referred to as "Juxin Technology") is a low-power system-level chip design manufacturer, the main business is the research and development, design and sales of high-end intelligent audio SoC chips, focusing on providing professional integrated chips for wireless audio, smart wearables and intelligent interaction and audio-related intelligent Internet of Things fields, and has gradually realized domestic substitution in the field of related chips. Juxin Technology has not only entered the supply chain of many terminal brands, but also entered the supply chain system of well-known ODM and OEM manufacturers in the industry such as Sino, Fengta and KONE.
At the time of its establishment, Juxin Technology set up an intellectual property and legal department, and equipped with full-time intellectual property staff, so that the intellectual property management work is more scientific and reasonable, and the connection between the acquisition, maintenance and application of intellectual property rights is closer. Based on the perfect intellectual property management system, Juxin Technology's intellectual property work has achieved remarkable results, and the achievements of scientific and technological innovation have been effectively guaranteed. Juxin Technology was rated as "National Intellectual Property Demonstration Enterprise" and "Guangdong Integrated Circuit Industry Patent Advantage Enterprise", and a number of patents won the "China Patent Award" and "Guangdong Patent Award".
As of November 30, 2021, Juxin Technology has a total of 275 patents worldwide, of which 245 have been obtained in Chinese mainland, including 213 inventions, 17 utility models, 15 designs, 66 software copyrights, and 58 integrated circuit layout designs.
In this competition, Juxin Technology's project is "Bluetooth Audio SoC Master Chip Layout Design", which won the Excellence Award in the Design Group.
Q: Please introduce the basic situation, technical highlights and value of the projects.
Juxin Technology: The Bluetooth audio SoC master chip is a single chip with high integration of complete Bluetooth communication functions, including noise reduction, sound processing and power management modules, with rich digital-to-analog interfaces and built-in Nor Flash flash memory. The company's Bluetooth audio SoC chip is mainly used in Bluetooth speakers and Bluetooth headsets. In addition, Bluetooth speaker chips are usually rich in system resources and interfaces, with good scalability. In addition to portable Bluetooth speakers, they are also widely used in various types of smart Internet of Things markets, such as conference speakers, TV speakers, Bluetooth transceivers, smart car products, etc.
Bluetooth audio SoC main control chip layout design by reasonable consideration of digital, power module, Bluetooth module, audio module area and shape splicing, effectively arrange the position of the power supply / ground pad and the position of the internal electrostatic discharge module, in reducing the size of the internal voltage drop to achieve low power consumption at the same time, combined with the circuit skills to achieve the whole chip of high Bluetooth performance, high audio indicators and high antistatic shock and other capabilities. The product that uses the Bluetooth audio SoC master control chip layout to design the tape-out supports Bluetooth low energy mode and has good reception sensitivity. Under the condition of ensuring the low power consumption of the system, it can provide ideal computing power for audio pre- and post-processing, support multi-segment mixing mode and multi-segment dynamic range control, and have industry-leading sound quality sound effects.
Audio transmission is the earliest and most important application field of Bluetooth technology, since the introduction of Bluetooth technology, it has presented a trend of continuous technological innovation and continuous growth of terminal applications. Since audio transmission is the most mature and most complete application scenario of Bluetooth Internet of Things devices and wearable technology, Bluetooth audio devices have also become the primary traffic entrance of intelligent interconnection in recent years. In addition, Bluetooth technology will also shine on healthy sports wearable devices such as assistive listening devices and wrist wearers, and form the next outlet industry.
Q: What preparations did the team make before participating in the Wangao Competition? What are your plans for the future?
Juxin Technology: We always believe that whether it is the preliminary round, the semi-finals or the finals, it is a learning process. Before the competition, we sorted out the intellectual property rights of the project, and only sorted out the Bluetooth technology patents related to the project. In the different stages of the competition, with a better understanding of the participation requirements, we continued to sort out the relevant intellectual property rights involved in the project, and found that our project also had relevant patent/software copyrights in audio, low power consumption and integrated technology of the entire chip, and some innovative technologies could be patented. Therefore, the process of participating in the competition is also a process of learning and improving the team's awareness of all aspects of intellectual property rights, which we feel is the biggest gain.
In the future, we will apply for patents on the innovative technologies sorted out by the project during the competition process to strengthen the intellectual property protection of the technology.
