    Abstract: A muffling device includes an acquisition circuit, configured to obtain reference sound wave information of a user. The muffling device includes a modulation circuit, configured to analyze an acoustic wave characteristic of the reference sound wave information to obtain a characteristic parameter of the reference sound wave information. The muffling device includes a muffling circuit, configured to generate compensated sound wave information according to the characteristic parameter of the reference sound wave information. The muffling device includes a correction circuit, configured to compare muffed sound wave information superimposed by the compensated sound wave information and the reference sound wave information with the reference sound wave information, and feed back a comparison result to the muffling circuit. The muffling circuit can adjust the compensated sound wave information according to a fed back comparison result. The muffling device includes an output circuit, configured to output adjusted compensated sound wave information.

    Abstract: The present disclosure relates to a technical field of display substrate inspection. The present disclosure discloses an inspection device and an inspection system for display substrate. The inspection device includes a support member, a turning table and a first drive device. The turning table includes: a carrier pivotally mounted on a pivot shaft, the carrier having an observation aperture through its thickness direction; and positioning clamps which are mounted on the carrier and are used to retain the display substrate in the range of the observation aperture. The first drive device is in transmission connection with the pivot shaft of the carrier in order to drive the turning table to rotate around the pivot shaft. When inspecting the appearance of the display substrate by the above mentioned inspection device, omnidirectional inspection of the display substrate can be achieved by turning the turning table. Moreover, the contact between the inspector and the display substrate can be avoided, the risk of damaging the display substrate during appearance inspection can be decreased, and therefore defects of the display substrate caused by appearance inspection can be reduced.
