Publication number: 20100119091Abstract: An acoustic reproduction device includes first speaker units 12 and 15 that emit sound in an inward direction and second speaker units 13 and 16 that emit sound in a forward or outward direction. The first speaker units are arranged at positions symmetrical with respect to a listening center axis, and so are second speaker units. The device further includes first and second processing units that process center channel signals as signals for the first and the second speaker units, respectively. Front channel signals are superimposed on an output signal of the second processing unit. The first processing unit includes a HPF 33 and a first high-shelf block 34 for boosting a high-range component. The second processing unit includes an LPF 38, a low-shelf block 36 for attenuating a low-range component, and a second high-shelf block 37 for attenuating a high-range component.Type: ApplicationFiled: March 7, 2008Publication date: May 13, 2010Applicant: PANASONIC CORPORATIONInventors: Suemei Fukuhara, Tsunenari Nishikawa, Shoji Tanaka

Patent number: 6343132Abstract: The present invention provides a loudspeaker capable of matching a sound image and a picture image on a screen of an image reproducer with each other in simple construction and a simple method of installation. The loudspeaker is located above the image reproducer in the vicinity thereof and so constructed as to reproduce a center channel signal in a multichannel sound signal for a movie or the like as a principal object, which comprises a main speaker unit, particular band preventing means for suppressing the level of a particular band in a band of not less than approximately 4 kHz of the main speaker unit, a sub-speaker unit, particular band passing means connected to the sub-speaker unit for passing only the particular band, and a dispersing device located on a front surface of the sub-speaker unit and so constructed that a reproduced sound radiated from the sub-speaker unit is mainly composed of a diffused sound.Type: GrantFiled: February 26, 1998Date of Patent: January 29, 2002Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Suemei Fukuhara, Isao Kuramitsu, Tatsuya Omori, Toshiyuki Mizutani

Patent number: 5140460Abstract: A motion-picture screen for projecting an optical image, which comprises a weaved knit having an adequate air permeability. One surface of the weaved knit is coated with a colored material so as to keep a high acoustic permeability concurrently with shutting the light from a wall or the like existing at the rear side of the screen. The other surface of the weaved knit is used as a surface onto which the optical image is projected by a projector, thereby providing an excellent contrast and a high image quality on the screen.Type: GrantFiled: November 5, 1991Date of Patent: August 18, 1992Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Suemei Fukuhara, Satoshi Kageyama
