The present technique relates to an earhole-wearable sound collection device, a signal processing device, and a sound collection method for realizing sound collection at a high S/N ratio, with noise influence being reduced not by a noise reduction process. In the earhole-wearable sound collection device, a microphone that collects emitted speech voice is provided in a space that is substantially sealed off from outside and connects to an ear canal of the wearer (the speaker). In a sound collection signal obtained through the ear canal, the emitted speech voice component is dominant over the noise component particularly at low frequencies. Therefore, the S/N ratio of an emitted speech voice collection signal can be improved by extracting the low-frequency component of the sound collection signal with the use of a LPF.

Earhole-wearable sound collection device, signal processing device, and sound collection method

Provided are an earhole-wearable sound collection device, a signal processing device, and a sound collection method for sound collection at a high S/N ratio, with noise influence being reduced not by a noise reduction process. In the earhole-wearable sound collection device, a microphone that collects emitted speech voice is provided in a space that is substantially sealed off from outside and connects to an ear canal of the wearer (the speaker). With the microphone being located in the space sealed off from outside, emitted speech voice that propagates through the ear canal of the wearer is collected. In a sound collection signal obtained through the ear canal, the emitted speech voice component is dominant over the noise component particularly at low frequencies.

An earphone device includes a housing having a driver unit, and a sound guide tube mounted on a front surface of the housing to protrude from the front surface, in which the sound guide tube is disposed at a position deviated from a center position of the housing.

Earphone device

There is provided a headphone device including: an external magnet type magnet unit that is disposed outside a voice coil, and vibrates the voice coil; and a diaphragm that is vibrated by vibration of the voice coil, and formed of a material in which a dome section having an outward concave shape on an inner circumference of the voice coil is continuous with an edge section outside the voice coil.

Headphone device

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.

Sound output device and sound guiding device

The present technique relates to a processing device and a processing method for realizing sound collection at a high S/N ratio, with noise influence being reduced not by a noise reduction process. In the processing device, a microphone that collects emitted speech voice is provided in a space that is substantially sealed off from outside and connects to an ear canal of the wearer (the speaker). With the microphone being located in the space sealed off from outside, emitted speech voice that propagates through the ear canal of the wearer is collected. In a sound collection signal obtained through the ear canal, the emitted speech voice component is dominant over the noise component particularly at low frequencies Further, an equalizing process for reducing muffled sound that is generated when sound is collected through the ear canal is performed on the sound collection signal.

Processing device and a processing method for voice communication

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.

Sound output device, sound output method, and sound output system

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.

Sound output device, sound generation method, and program

Provided is a wearable device that is worn on a human ear and mainly outputs or inputs sound. The outer casingis formed into an elongated shape so as to fit the cymba conchaeformed between the antihelix inferior crusand the crus helicis. The sound generating unitincludes a vibration elementand a weight. The vibration elementhas an elongated shape along the longitudinal direction of the outer casing, and has one end fixed to the inner wall of the outer casing, and the other end to which a weightis attached, the other hand being an open end. By applying an alternating electric field to the vibration element, vibration corresponding to audio is generated.

Wearable device

Sound output device, sound output method, and sound output system for sound reverberation

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 deviceincludes a sound generating portionthat generates a sound, a sound guiding portionthat takes in the sound generated in the sound generating portionfrom one end, and a holding portionthat holds the sound guiding portionin the vicinity of the other end. The holding portionis engaged with an intertragic notch, and supports the sound guiding portionsuch that a sound output hole of the other endof the sound guiding portionto face a depth side of an ear canal. Even in a state where the listener wears the sound output device, the sound output devicedoes not block an ear cavity of the listener, and the listener can listen to the ambient sound.
