    摘要: An electrostatic atomizing apparatus (1) includes an air flow path (200), a humidifier (10), and electrode section (70), and a control unit (80). The air flow path (200) has an air intake port (21) and an air exhaust port (22). The humidifier (10) includes a portion of the air flow path (200) and humidifies air taken in through the air intake port (21). The electrode section (70) includes a portion of the air flow path (200) and produces charged particulate water by causing water in the air humidified by the humidifier (10) to condense on an electrode and applying voltage to the electrode. A flow rate of the air in the air flow path (200) is regulated in accordance with at least one of humidity and temperature of the air taken in through the air intake port (21).

    摘要: A noise reduction device (10) is connectable to a plurality of sound acquisition devices (7) and a plurality of control sound output devices (5) for reducing noises in a given space (10) where seats are arranged and a sound field can be formed. The device (10) includes a sound receiver (12), a control sound generating unit (13), a control sound transmitter (14), a detecting unit (17), and an operation control unit (16). The sound receiver (12) receives a sound signal from at least two of the plurality of sound acquisition devices. The control sound generating unit (13) generates a control sound signal for reducing noise with respect to the sound signal. The control sound transmitter (14) outputs the control sound signal to each of control sound output devices. The detecting unit (17) detects a change of state of the sound field. The detecting unit (17) acquires, for example, seat information for specifying the reclining state of a seat. The operation control unit (16) controls the generation of the control sound signal by the control sound generating unit (13) based on the change of state of the sound field including the seat information.

    摘要: An electrostatic atomizing system (1) includes an air flow path (200) having an air intake port (21) and an air exhaust port (22), a humidifying device (10), an electrostatic atomizing apparatus (30), a first sensor (17b, 18b), and a control unit (11). The humidifying device (10) humidifies the air taken in through the air intake port (21). The electrostatic atomizing apparatus (30) includes an electrode section (31) operable to produce charged particulate water by causing the water in the air humidified by the humidifying device (10) to condense on an electrode and applying voltage to that electrode. Moreover, the electrostatic atomizing apparatus (30) exhausts air that contains the charged particulate water through the air exhaust port (22). The first sensor (17b, 18b) senses at least one of humidity and temperature of the air humidified by the humidifying device (10). The control unit (11) determines, based on a sensing result of the first sensor (17b, 18b), if there is a fault in the humidifying device (10) or the electrostatic atomizing apparatus (30), and outputs the result of the determination.

    摘要: An electrostatic atomizing apparatus (1) includes a main body portion (1a), a container (10), a first air flow path (210), a second air flow path (220), an electrostatic atomization unit (70), and an air flow generation unit (90). The container (10) is detachable from the main body portion (1a), is capable of storing a liquid (W), and includes a first ventilation hole (11) and a second ventilation hole (12). The first air flow path (210) includes a first end that includes an air suction port (21a), and a second end (22b) that connects to the first ventilation hole (11). The second air flow path (220) includes a third end (22a) that connects to the second ventilation hole (12), and a fourth end that includes an air exhaust port (22b). The electrostatic atomization unit (70) is disposed on the second air flow path (220). The air flow generation unit (90) generates an air flow that causes air to flow through the first air flow path (210), through the container (10), and through the second air flow path (220).

    摘要: In the noise reduction device (530), the sound receiver (531) receives a noise signal acquired from the microphone (520). The sound source input unit (537) receives an input of a sound source signal from a sound source. The sound adjuster (53A) changes the intensity of the sound source signal relative to the intensity of the noise signal. The control sound generator (532) generates a control sound signal that reduces the noise signal. The control unit (533) controls the change of the intensity of the sound source signal and the generation of the control sound signal. The sound output (560) outputs the control sound signal to the speaker (540). The sound output (560) outputs to the speaker (540) the sound source signal at the intensity changed by the sound adjuster (53A).
