Clarion has developed the Full-Digital Speaker, which balances eco-friendliness with premium sound, as a world’s first development for the automotive field. The development combines digital signal processing technology, “Dnote”*1, and Clarion’s long nurtured in-vehicle audio technologies. This enables to reproduce digital sound quality without deterioration in high quality by feeding digital signals of, for instance CDs, directly into speakers. In addition, with the new technology, drastic saving in electric power can be achieved with driving voltage of less than a half and power consumption about 1/8*2, both of conventional speakers. Through this technology, we will be promoting the commercialization of onboard audio systems that are ideal for next-generation eco cars.
∗1 Dnote: Registered trade mark of Trigence Semiconductor. This is a technology to reproduce voices by feeding modulated audio signals directly into multiple speaker units or voice coils.
∗2 power consumption about 1/8: comparison with our products
