  • VOICE RECOGNITION DEVICE
    Publication number: 20190180755
    Abstract: A voice recognition device comprising: a battery; a first voice recognition section which performs voice recognition; and a second voice recognition section which performs voice recognition and in which electric power consumption is higher than the first voice recognition section; wherein the second voice recognition section performs voice recognition when driving by electric power from an external power supply, and the first voice recognition section performs voice recognition when driving by electric power from the battery.

  • Music reproducing device with active control ground mode
    Patent number: 9762197
    Abstract: To realize active control ground that sets inverted output of an amplification circuit to ground with simple configuration. A DAP 1 comprises a positive side DAC 7 that D/A-converts digital audio data into analog audio data, a positive side amplification circuit 9 that amplifies the analog audio data that the DAC 7 D/A-converts, a negative side DAC 8 that D/A-converts the digital audio data into the analog audio data, and a negative side amplification circuit 10 that amplifies the analog audio data that the DAC 8 D/A-converts, and a CPU 2. The CPU 2 mutes the DAC 8 in case of an ACG mode that sets output of the amplification circuit 10 to ground.

  • Music reproducing device with first and second D/A converters for converting audio signals prior to inversion
    Patent number: 9712919
    Abstract: To reduce signal output and wiring to a D/A converter (DAC). A DAP 1 comprises a DAC 7 that D/A-converts LR 2 channels digital audio data into LR 2 channels analog audio data, an amplification circuit 9 that amplifies the LR 2 channels analog audio data that the DAC 7 D/A-converts, a DAC 8 that D/A-converts the LR 2 channels digital audio data into the LR 2 channels analog audio data, and an amplification circuit 10 that amplifies inverted LR 2 channels analog audio data that the LR 2 channels analog audio data that the DAC 8 D/A-converts is inverted.
