Abstract: 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.

Abstract: The present technique relates to an earhole-wearable sound collection device, a signal processing device, and a method for realizing sound collection at a high S/N ratio. 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. Therefore, the S/N ratio of an emitted speech voice collection signal is improved by an equalizing process for reducing muffled sound that is generated when sound is collected through the ear canal on the sound collection signal.

Alternatively, 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. As a result, higher sound quality can be achieved.

Abstract: Sound quality is improved. A plurality of speaker units including a first speaker unit of a dynamic type, an arrangement case having an inner space formed as an arrangement space in which the plurality of speaker units is arranged, and a sound conduit protruding from the arrangement case and provided as a path for sound output from the plurality of speaker units are provided, the first speaker unit has a highest sound output band among the plurality of speaker units, the axial direction of the sound conduit and the axial direction of the first speaker unit are oriented in the same direction, the speaker units except the first speaker unit are arranged around the first speaker unit or on the opposite side to the sound conduit with the first speaker unit therebetween, and a central axis of the first speaker unit is positioned further on the inner side than the inner peripheral surface of the sound conduit.
