Abstract
A second housingis capable of moving in a direction in which the second housing covers one surface of a first housing. Oscillating elements of an oscillating element groupare arranged in a matrix and oscillate sound waves outward from the one surface of the first housing. A control unit controls the plurality of oscillating elements. A sound wave sensor constitutes the same matrix as the plurality of oscillating elements and detects sound waves having a specific wavelength. The detection results of the sound wave sensor are output to the control unit. A frame body holds the plurality of oscillating elements and the sound wave sensor. The control unit oscillates sensor sound waves having a specific wavelength outward from at least one of the oscillating elements. The control unit determines that the second housingcovers the one surface of the first housingwhen the sound wave sensor detects the sound waves having the specific wavelength.
