Abstract: A semiconductor device includes: a semiconductor layer; first and second transistors; one or more first source pads and a first gate pad of the first transistor in a first region of the upper surface of the semiconductor layer; and one or more second source pads and a second gate pad of the second transistor in a second region of the upper surface adjacent to the first region in a plan view of the semiconductor layer. In a plan view of the semiconductor layer, a virtual straight line connecting the centers of the first and second gate pads passes through the center of the semiconductor layer and forms a 45 degree angle with each side of the semiconductor layer. An upper surface boundary line between the first and second regions monotonically changes in the directions of extension of the longer and shorter sides of the semiconductor layer.

Abstract: A semiconductor device of a hybrid type includes: a light-emitting element forming a power loop; a semiconductor integrated circuit element including a switching element; and a bypass capacitor. The light-emitting element and the switching element constitute a layered body in which respective principal surfaces of the light-emitting element and the switching element are layered in parallel and face-to-face. The bypass capacitor includes one electrode connected to a lower element of the layered body, and an other electrode connected to an upper element of the layered body. In a plan view, when a direction from the one electrode to the other electrode inside the bypass capacitor is a first direction, the bypass capacitor is arranged so that a side of the bypass capacitor parallel to the first direction includes a portion that is parallel to and faces one peripheral side of the layered body.

Abstract: A sound reproducing device includes a decoder section (1200) configured to decode an audio-signal bit stream input from the outside world, and to generate a decoded PCM signal; a control section (1100) configured to identify reproduction conditions from reproduction-instruction information obtained from the outside world and decoding information obtained from the decoder section (1200), and to provide a reproduction instruction; and an additional-audio addition section (1500) configured to process additional audio data input from the outside world, to add a result with the decoded PCM signal, and to output a result as an output PCM signal.

Abstract: An AV system includes a camera-equipped loudspeaker provided with a camera. The camera is united with a loudspeaker body, and captures an image in a direction in which the loudspeaker body outputs a sound. The recognition unit recognizes a location of a listener from an image of the camera, and detects an orientation of the loudspeaker body relative to the listener. The sound control unit performs signal processing on a given sound signal for generating an output signal, and outputs the output signal as an acoustic signal to the loudspeaker body.
