    摘要： Provided is an information processing apparatus that carries out a process of deriving a head related transfer function. The information processing apparatus includes a detection unit that detects a position of a head of a user, a storage unit that stores a head related transfer function of the user, a determination unit that determines a position of a sound source for measuring the head related transfer function of the user based on the position of the head detected by the detection unit and information stored in the storage unit, a control unit that controls the sound source to output measurement signal sound from the position determined by the determination unit, and a calculation unit that calculates the head related transfer function of the user based on collected sound data obtained by collecting, at the position of the head, the measurement signal sound output from the sound source.

    摘要： To provide an excellent sound output device which is worn on an ear of a user and used. The sound output device includes a sound generation part and a holding part that has an opening portion and holds the sound generation part in the vicinity of an entrance of an ear canal of a user. The holding part includes a ring body having the opening portion, and a housing of the sound generation part is integrated with a part of the ring body. The sound generation part includes a sound generation element having a dynamic type driver, and has a hollow exhaust part joining with a rear surface of the housing of the sound generation part. The exhaust part extends from a rear surface side of the housing across an intertragic notch and has an exhaust hole outside an auricle.

    摘要： According to the present disclosure, a sound output device includes: a sound acquisition part configured to acquire sound to be output to the other end of a sound guide part, one end of which is arranged near an entrance of an ear canal of a listener, the sound guide part having a hollow structure; and a head-related transfer function adjustment part configured to adjust a head-related transfer function of sound captured by the sound guide part. Since the head-related transfer function adjustment part adjusts the head-related transfer function of sound captured by the sound guide part, it is possible to listen to both ambient sound and sound provided from a sound output device such that the listener does not feel strangeness even in the state in which the listener is wearing the sound output device.
