Abstract: Provided is a sound output apparatus that is used by being worn in the vicinity of the ear of a listener and is capable of outputting sound over a wide frequency band.
The sound output apparatus includes: a first sound generation unit configured to generate a low frequency band; a sound guiding unit with a hollow structure, having one end coupled to the first sound generation unit, and the other end as a sound emission unit including an open end; and a second sound generation unit that is disposed at a place closer to the sound emission unit than the first sound generation unit and generates a high frequency band. It is preferable that the sound guiding unit have a joint unit that takes in the sound from the second sound generation unit and a section from the joint unit to the sound emission unit have a low impedance.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: Provided is a sound output device worn on an ear of a listener and used, and having listening characteristics of an ambient sound in a wearing state. A sound output device 100 includes a sound generating portion 110 that generates a sound, a sound guiding portion 120 that takes in the sound generated in the sound generating portion 110 from one end 121, and a holding portion 130 that holds the sound guiding portion 120 in the vicinity of the other end 122. The holding portion 130 is engaged with an intertragic notch, and supports the sound guiding portion 120 such that a sound output hole of the other end 122 of the sound guiding portion 120 to face a depth side of an ear canal. Even in a state where the listener wears the sound output device 100, the sound output device 100 does not block an ear cavity of the listener, and the listener can listen to the ambient sound.
