By the reverse operation of the actuator 130, the upper grip portion 120 is raised to the original position. Here, the ascent control stores the position value descending from the initial position, and if it is used as the ascent control value using this, the upper grip part 120 can be simply moved to the original position. The reason for using the descending position value is because the size of the smartphone varies, so the descending position varies depending on the size of the smartphone.

When the upper grip portion 120 rises and loses the mounting force of the smartphone 1, the driver may remove the smartphone 1 in step S109. If the release button 101 is not operated while the smartphone 1 is mounted, the current mounting state is maintained as in step S107.

In this way, the driver operates the actuator automatically to fix the smartphone by simply placing the smartphone on the lower grip portion provided in the audio device, thereby increasing convenience for smartphone mounting and using a separate cradle. There is no need to damage the driver's discomfort by installing a separate cradle without compromising the aesthetics of the vehicle.
