Patent number: 9472095Abstract: A second housing 200 is capable of moving in a direction in which the second housing covers one surface of a first housing 100. Oscillating elements of an oscillating element group 400 are arranged in a matrix and oscillate sound waves outward from the one surface of the first housing 100. 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 housing 200 covers the one surface of the first housing 100 when the sound wave sensor detects the sound waves having the specific wavelength.Type: GrantFiled: November 24, 2011Date of Patent: October 18, 2016Assignee: NEC CORPORATIONInventors: Yuichiro Kishinami, Yasuharu Onishi, Motoyoshi Komoda, Nobuhiro Kawashima, Yukio Murata, Jun Kuroda, Shigeo Satou

Patent number: 9306148Abstract: In an electro-acoustic transducer 100 which is an oscillator device, center positions of principal surfaces of piezoelectric elements 130 that are positioned on both surfaces of an elastic member 120 are different from each other. As such, since the two piezoelectric elements 130 are disposed asymmetrically on the upper and lower sides in the electro-acoustic transducer 100, it is possible to prevent vibrations of reversed phases at the time of divided vibration in which the reversed phases overlap with each other. In other words, since it is possible to prevent the generation of sound waves due to the vibration of local reversed phases, the sound pressure level can be improved.Type: GrantFiled: December 20, 2011Date of Patent: April 5, 2016Assignee: NEC CORPORATIONInventors: Yasuharu Onishi, Yuichiro Kishinami, Shigeo Satou, Jun Kuroda, Yukio Murata, Motoyoshi Komoda, Nobuhiro Kawashima, Tatsuya Uchikawa
