摘要： A sound output device includes a sound generating portion that generates a sound, a sound guiding portion that takes in the sound generated in the sound generating portion from one end, and a holding portion that holds the sound guiding portion in the vicinity of the other end. The holding portion is engaged with an intertragic notch, and supports the sound guiding portion such that a sound output hole of the other end of the sound guiding portion to face a depth side of an ear canal. Even in a state where the listener wears the sound output device, the sound output device does not block an ear cavity of the listener, and the listener can listen to the ambient sound.

摘要： According to the present disclosure, a sound output device includes a sound acquisition part that acquires a sound signal generated from an ambient sound, a reverb process part that performs a reverb process on the sound signal, and a sound output part that outputs a sound generated from the sound signal subjected to the reverb process, to a vicinity of an ear of a listener. This configuration allows a listener to hear sound acquired in real time to which desired reverberation is added.

摘要： A signal processing apparatus includes a signal processor configured to: generate a first noise reduction signal using an adaptive filter based on a signal output from a first input apparatus, and cause the generated first noise reduction signal to be output by a first output apparatus; and generate a second noise reduction signal using a feedback filter based on a signal output from a second input apparatus, and cause the generated second noise reduction signal to be output by a second output apparatus. The feedback filter has a fixed feedback coefficient. The first input apparatus is located at a first noise-cancellation target location in an environment, and the second input apparatus is located at a second noise-cancellation target location in the environment, which may be different from the first noise-cancellation target location.

摘要： Provided is a wearable device that is worn on a human ear and mainly outputs or inputs sound. The outer casing 110 is formed into an elongated shape so as to fit the cymba conchae 306 formed between the antihelix inferior crus 302b and the crus helicis 309. The sound generating unit 120 includes a vibration element 121 and a weight 122. The vibration element 121 has an elongated shape along the longitudinal direction of the outer casing 110, and has one end fixed to the inner wall of the outer casing 110, and the other end to which a weight 122 is attached, the other hand being an open end. By applying an alternating electric field to the vibration element 121, vibration corresponding to audio is generated.
