Patent number: 7292695Abstract: A bone conductive speaker is downsized without causing any loss in efficiency, simple in construction low in cost, and comprises yoke (2), magnet (3) disposed in a central area of the yoke, and voice coil (4) wound on the magnet. The yoke has its peripheral area divided into a plurality of upright portions; of the upright portions, each of first ones (5) oppositely disposed from each other is provided with a first engaging means (9) in its upper surface; second engaging means (8) each corresponding to the first engaging means are provided in a vibrating plate (7). The vibrating plate is mounted on a lid portion of the housing in a manner such that the vibrating plate is disposed on the upright portions of the yoke and fixedly mounted by means of the second engaging means in a manner such that the vibrating plate floats in the housing.Type: GrantFiled: May 27, 2003Date of Patent: November 6, 2007Assignee: Temco Japan Co., Ltd.Inventor: Kazuji Kobayashi

Publication number: 20070160238Abstract: The object is to provide a bone conduction device. The device is simple in construction, thin in thickness, small in leakage in magnetic flux, excellent in performance, and comprises: abase yoke (1) carrying both a voice coil (3) and a magnet (4); and, a front yoke (5). The yoke (5) assumes a flat plate-like shape and is loosely disposed between: an upper surface of a magnetic pole of the base yoke (1); and, the front yoke (5) to provide a necessary clearance between these yokes. The device is characterized in that the clearance is produced by means of a resilient element (6), which is disposed in an outer peripheral portion of the base yoke (1) to receive the front yoke (5) thereon. Preferably: the base yoke (1) has a circular base (7); and, the resilient element (6) assumes an arcing shape extending along the base (7).Type: ApplicationFiled: March 4, 2005Publication date: July 12, 2007Applicant: TEMCO JAPAN CO., LTD.Inventor: Kazuji Kobayashi

Publication number: 20070160253Abstract: The object is to provide a talking device, which employs a bone conduction speaker. The device is small in size, light in weight and excellent in fittingness. Further, the device enables its users to communicate with each other without suffering from any difficulty in hearing even in a noisy environment. The device uses a bone conduction speaker, and may also have an ornamental function to serve as a pendant during non-use of the device. The device comprises a bone conduction speaker (5), an air conduction microphone (6) and a wireless circuit. The device is capable of: fitting to the user's body; and, connecting to a cell phone (8) by wireless through the wireless circuit. Both the bone conduction speaker (5) and the wireless circuit are packed in a head portion (2) of the ornamental pendant.Type: ApplicationFiled: March 30, 2005Publication date: July 12, 2007Inventors: Ryuichi Takei, Tetsuo Wakabayashi, Kazuji Kobayashi

Patent number: 6222657Abstract: In the apparatus, in accordance with the presence or absence of a barrier, arrangement of its light-receiving and its light-emitting element is changed to avoid interference with its proper light-receiving operation from the barrier, which makesso the apparatus free from noise problems, malfunctions and like troubles caused by the interference. In construction, a cover 2 permeable to infrared is rotatably mounted on a base 1. A stationary base plate 9 and a movable base plate 10, which is rotatable together with the cover 2, are stacked together inside the cover 2 to realize a two-layer arrangement. Each of these base plates 9, 10 carries a light-receiving element 7, 12 and/or a light-emitting element 8, 13, and assumes a substantially semicircular shape.Type: GrantFiled: September 24, 1998Date of Patent: April 24, 2001Assignee: Temco Japan Co., Ltd.Inventors: Shouji Fujino, Hiroaki Yanagisawa, Jiro Nawa, Kazuji Kobayashi
