An array of drivers projects sound upwards from a top surface of the portable device to form upward-firing speakers; a set of speakers projects sound downwards from a bottom surface of the portable device to form downward-firing speakers. A decoder/renderer component receives immersive audio content, decodes height audio signals from the content and sends direct audio signals to the downward-firing speakers. A crossover performs a high-pass filter function to pass high frequency components of the decoded height audio signals to the upward-firing speakers and low frequency components of the decoded height audio signals to the downward-firing speakers."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Near-field rendering of immersive audio content in portable computers and devices","description":"Embodiments for a speaker system that produces a near-field sound pattern for rendering immersive audio content in a portable device.
