  • Patent number: 12375843
    Abstract: Provided is a sound output device including a drive unit that has a sound output section inside and that is formed in an annular shape and an electric unit that has a drive control section inside and that is coupled to the drive unit. A space inside the drive unit is formed as an intake hole that takes in an external sound. The sound output device is attached to an ear with the drive unit inserted into a cavum concha. Accordingly, in a state in which the electric unit is coupled to the drive unit and the drive unit is inserted into the cavum concha to be attached to the ear, an external sound taken in from the intake hole that is the space inside the drive unit goes to the external auditory canal. Therefore, a stable and favorable wearing state on the ear can be ensured, and at the same time, a state in which an external sound is taken in naturally can be ensured.

  • Patent number: 12025069
    Abstract: A hybrid control method controls a hybrid vehicle. A control unit sets a rotational speed threshold value at which a continuous gear tooth striking sound occurring in a gear mechanism connecting an electric power generation motor to the internal combustion engine is not a problem in terms of vehicle quality. The control unit generates negative pressure while maintaining the engine rotational speed in the firing state where the engine rotational speed is equal to or greater than the rotational speed threshold value. Also, the control unit generates negative pressure after switching from the firing state to a motoring state where the internal combustion engine is rotated by the electric power generation motor and where the engine rotational speed is less than the rotational speed threshold value.
