Abstract: Rockchip micro RKNanoD has the characteristics of low power consumption, high efficiency and great cost advantage. Arm Cortex-M3 dual-core processor architecture, integrated audio decoder hardware accelerator, can achieve audio lossless decoding, so that audio products have better sound reproduction capabilities.
According to a report released by canalys, an authoritative market research agency, as of the end of 2018, the number of smart speakers in the world was 114 million units. At the end of 2019, the number of units was 207.9 million units, an increase of 82.4% year-on-year. It is estimated that by 2024, the number of smart speakers in the world will reach 640 million units, and the market demand will continue to rise, and the competition will become increasingly fierce.
The data shows that sound quality and the stability of wireless connectivity are the focus of consumers' purchase of smart speakers. This puts forward higher requirements for digital audio chips, especially in the high-end intelligent market. For example, hiRes-certified speakers, which are highly respected by high-end enthusiasts, have stronger market dominance. The masterpiece of the HiRes speaker, Sony's flagship HT-Z9F, is praised by discerning consumers with its excellent sound quality and ultra-stable wireless connection.
Through disassembly, it was found that the wireless control module of the Sony HT-Z9F subwoofer uses a Rockchip micro RKNanoDHiFi audio player chip.
