Patent number: 10771840Abstract: A sink device is bi-directionally communicably connected to the source device. The sink device includes a first memory, and a controller. Stored in the first memory is a plurality of pieces of audio format information including information representing an audio format that the sink device can process. The controller selects, from among the plurality of pieces of audio format information stored in the first memory, one piece of audio format information corresponding to receiver format information representing an audio format that a receiver device connected to the sink device can process. The controller then outputs the selected audio format information to the source device.Type: GrantFiled: February 25, 2016Date of Patent: September 8, 2020Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Yoshihiro Moriie, Akihiro Fuke, Kazuki Adachi, Hiroaki Nakayama, Takuma Adachi

Patent number: 7957544Abstract: The potential of a smoothing capacitor for a speaker is smoothly changed by controlling the potential with use of a PWM signal and switching between outputting the PWM signal and an actual audio signal, thereby suppressing a pop sound. The scale of circuitry is reduced and cost is lowered by implementing a PWM circuit in a one-chip microcontroller. Noise is eliminated by outputting a pulse that has been divided in the PWM signal generation stage.Type: GrantFiled: November 7, 2006Date of Patent: June 7, 2011Assignee: Panasonic CorporationInventors: Kazuki Adachi, Tetsuro Sugioka, Kiyomi Kimura

Patent number: 7425673Abstract: In a tone output device 100, an oscillator 102 outputs a clock 141 that is emitted by a crystal resonator. A multiplication circuit 103 outputs a clock 142 that is generated by multiplying the clock 141. A timing control circuit 104 outputs a timing signal 150 generated based on the clock 142 for operations of a CPU 105. The CPU 105 operates in sync with the timing signal 150. The DA converter 115 operates in sync with a signal generated based on the clock 141. The timing adjustment circuit 114 detects deviation of the clock 142 from the clock 141 resulting from frequency jitter of the clock 142, and prevents occurrence of clock racing.Type: GrantFiled: October 20, 2006Date of Patent: September 16, 2008Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Kosei Fujisaka, Tetsuro Sugioka, Kazuki Adachi, Kiyomi Kimura, Tsuyoshi Takayama
