Abstract: A device system includes an acoustic device, a sensor, and a sound processor. The acoustic device is configured to be worn by a user. A sensor is configured to detect a movement of a shielding object. The sound processor is configured to generate sound with a first sound quality for a block state in which the shielding object blocks a virtual sound source localized on an opposite side of the shielding object and emit the sound from the acoustic device. The sound processor is further configured to change a sound quality of the sound from the first sound quality to a second sound quality for a non-block state in which the shielding object does not block the virtual sound source, in response to the sensor detecting that the shielding object moves from a position blocking the virtual sound source.

Abstract: A sound control device includes: a first memory storing instructions; and a processor that implements the stored instructions to execute a plurality of instructions, including: a synthesizing task that synthesizes a synthesized sound signal from an input sound signal acquired from a sound input device and a reproducing sound signal acquired from a sound reproducing device; an outputting task that outputs alternately between the reproducing sound signal and the synthesized sound signal to a sound emitting device; a notification control task that outputs notifying information for causing a notifying device to notify for a notification period, which is an output period during which the outputting task is outputting the synthesized sound signal to the sound emitting device; and a registering task that registers, in a second memory, duration information specifying the notification period.

Abstract: A voice providing method includes obtaining position information from a voice reproducing device, and performing processing, in a case in which a first position of obtained position information and a second position of a virtual talker are in a predetermined relationship, to cause the voice reproducing device to reproduce voice for the virtual talker to have a dialogue with a user with content according to the user.

Abstract: An acoustic device includes a member which divides an ear canal of a user and an external space when being attached to an ear or the ear canal of the user, a memory that stores instructions, and a processor that executes the instructions. The instructions cause the processor to perform, acquiring a sound signal indicating a sound, applying a filter processing to the acquired sound signal, the filter processing being changed in accordance with a predetermined condition, and radiating the sound indicated by the sound signal applied with the filter processing to the ear canal.

Abstract: A method for cleaning a capillary tube for use in a wire bonding tool includes the step of applying an ultrasonic wave to the capillary tube, with the tip of the capillary tube being immersed in a cleaning solution, and with a tungsten wire being inserted in the capillary tube. Before the cleaning step, the capillary tube is ground by an abrasive sheet, with the capillary tube being empty.
