  • Patent number: 10674275
    Abstract: An electroacoustic transducer includes: a diaphragm; a frame that is disposed around the diaphragm so as to surround the diaphragm; an edge that closes a space between the diaphragm and the frame in a manner of forming a membrane so as to connect the diaphragm and the frame; a base body that supports the frame and has a through sound output hole in front of the diaphragm; a magnet that is attached to the frame; and a voice coil body that is attached to the diaphragm. The frame has an annular first fitting portion that is disposed around the diaphragm so as to surround the diaphragm. The base body has a second fitting portion that fits with the first fitting portion. The electroacoustic transducer further includes a sealing member that is made of a thermoplastic substance and seals a space between the first fitting portion and the second fitting portion fitted with each other.

  • Patent number: 10453416
    Abstract: A display driving circuit having a shift register is formed on the display panel. The shift register includes a first stage having first and second transistors and a second stage having a third and fourth transistor. A voltage of a control electrode of the first transistor is boosted by a voltage of a first pulse line changing from low to high. In an On state, the second transistor connects the control electrode of the first transistor and a constant voltage line. A voltage of a control electrode of the third transistor is boosted by a voltage of a second pulse line changing from low to high. In an On state, the fourth transistor connects the control electrode of the third transistor and a constant voltage line. The fourth transistor is switched on by a signal from the first stage.
