    摘要： A display substrate and a display device are provided. In the display substrate, the driving transistor includes an active pattern and a gate electrode, the active pattern includes a channel region, and an orthographic projection of the channel region on the base substrate at least partially overlaps with an orthographic projection of the gate electrode on the base substrate; the storage capacitor includes a first electrode plate and a second electrode plate. The first electrode plate is electrically connected with the gate electrode of the driving transistor; an orthographic projection of the second electrode plate on the base substrate at least partially overlaps with an orthographic projection of the first electrode plate on the base substrate, and does not overlap with an orthographic projection of the channel region of the driving transistor on the base substrate.

    摘要： [Problem] The present invention is directed to a higher-performance and higher-quality curved diaphragm speaker system without deficiency of performance for both a hearing-impaired person and a normal hearing person.
    [Solution] A speaker unit 10 according to the present invention includes at least a first diaphragm 1 having a corn shape, a second diaphragm 2 having a curved sheet shape, and a driver unit 3 that drives both the first diaphragm and the second diaphragm. A small diameter side 1a of the first diaphragm and one end side 2a of the second diaphragm are coupled to the driver unit. When the speaker unit is mounted in a housing 50 to be a speaker 100, a large diameter side 1b of the first diaphragm is coupled to a support plate 511 of a support member 51 that is a part of the housing, and the other end side 2b of the second diaphragm is coupled to a support leg 513 of the support member that is a part of the housing.
