Publication number: 20220390704Abstract: A lens unit includes a plurality of lenses arranged in an optical axis direction, a lens barrel, and a retainer. The lens barrel has an opening larger than outer diameters of the plurality of lenses and contains the plurality of lenses. The retainer holds the plurality of lenses by contacting, from a side adjacent to the opening in the lens barrel, one of the plurality of lenses that is closest to the opening. Each of the plurality of lenses has an object-side surface and an image-side surface which each include a flat portion that extends radially inward from an outer edge of the lens and that is perpendicular to the optical axis direction of the lens. Each of the plurality of lenses is held in planar contact with a holder at the flat portion. The retainer holds the plurality of lenses by biasing the plurality of lenses in the optical axis direction.Type: ApplicationFiled: October 9, 2020Publication date: December 8, 2022Applicant: KYOCERA CorporationInventors: Naoto OHARA, Michiaki HIRAOKA, Akihiko HIRAISHI, Hiroto YAHAGI, Keiichi NAGOSHI

Patent number: 9949036Abstract: An electronic device in which a vibration generator is attached to a panel allows further improvement in sound pressure characteristics. An electronic device (1) includes a housing (60), a panel (10) held by the housing (60), a vibration generator (30) attached to the panel (10), and a sheet member (80) between the housing (60) and the panel (10). The panel (10) deforms due to deformation of the vibration generator (30) to transmit human body vibration sound to an object that contacts the panel (10). A first portion of the sheet member (80) is joined to the panel (10), and a second portion of the sheet member (80) differing from the first portion is joined to the housing (60). Between the first portion and the second portion, the sheet member (80) includes an area to which neither the panel (10) nor the housing (60) is attached.Type: GrantFiled: December 22, 2014Date of Patent: April 17, 2018Assignee: KYOCERA CorporationInventors: Kenichi Ozasa, Takaaki Watanabe, Hiroto Yahagi, Hayato Mizuno

Patent number: 9363591Abstract: An electronic device is provided with a housing, a piezoelectric element, and a panel, which is attached to the housing and has a contact area contacting a part of human body, configured to vibrate by the piezoelectric element to generate a vibration sound to be transmitted by vibrating the part of human body, such that pressure from inside of the housing at the contact area of the panel is smaller than pressure from inside of the housing at different area from the contact area. Thereby the sound pressure property is improved, and thus the electronic device preferably transmits air conduction sound and vibration sound.Type: GrantFiled: May 20, 2013Date of Patent: June 7, 2016Assignee: KYOCERA CorporationInventors: Kenichi Ozasa, Hayato Mizuno, Hiroto Yahagi, Keiichi Nagoshi, Tsutomu Zaima, Koutatsu Kanayama, Tomoaki Nakamura, Hideo Tomioka, Takuji Masunaga, Tomohiro Inagaki
