In one embodiment, an ultrasonic speaker outputting ultrasonic signals can be transformed into first audio output signals, which are directional. A non-ultrasonic speaker can output second audio output signals. The embodiment can be configured to output the first audio output signals or the second audio output signals in a vehicle. Another embodiment can be configured to output the first and the second audio output signals together. Yet another embodiment can be configured to be personalized to hearing characteristics of a user, or to depend on sound level of an environment of the user. One embodiment can include a directional speaker attached to a vehicle, with its output steerable towards a user in the vehicle."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for directional sound","description":"Different embodiments of methods and apparatus to produce audio output signals are disclosed.
