Altec Lansing awarded patent for innovative side firing computer and television speaker surround sound design.
MILFORD, Pa.--(BUSINESS WIRE)--Oct. 3, 1996--Altec Lansing Technologies Inc. Thursday announced that it has been awarded a patent by the United States Patent and Trademark Office The United States Patent and Trademark Office (PTO or USPTO) is an agency in the United States Department of Commerce that provides patent protection to inventors and businesses for their inventions, and trademark registration for product and intellectual property for its new engineering breakthrough which achieves true surround sound An audio recording and playback system that uses five or more channels plus a subwoofer channel. See 5.1 channel and 3D audio. via computers, television and other entertainment systems through a unique side firing speaker system.
The patent covers the design and engineering of speaker systems that provide audiophile An individual who is very interested and enthusiastic about the sound quality of a stereo or home theater system. Quality audio components are designed to reproduce the audio without adding any distortion or coloration. quality surround sound for the computer and TV markets. Altec Lansing Altec Lansing Technologies, Inc. is a manufacturer and marketer of computer and home entertainment sound systems, headphones, and microphones for personal digital media. products, incorporating technologies covered by this new patent, deliver home theater An audio/video entertainment center that has a large-screen TV and hi-fi system with three speakers in the front (left, right and center) and left and right speakers in the rear. Starting in the early 1990s, video inputs were added to stereo receivers and preamplifiers. quality surround sound reproduction to multimedia computer and television users for the very first time.
The audio technology represented by this new patent includes the use of two side firing stereo speakers to reproduce four channels (surround, center, left and right) on a single listening plane. Other attempts to create the image of surround sound through two speakers has resulted in "virtual" rather than true multi-channel audio reproduction.
This innovative design also means greater audio intelligibility, articulation of discrete sounds and enhanced special effects special effects, in motion pictures, cinematographic techniques that create illusions in the audience's minds as well as the illusions created using these techniques. for computer and TV users without the need for additional speakers and complex wiring. As a result, audio quality and sound reproduction is maximized via computer and TV-delivered material, including entertainment and games, educational titles and business presentations.
"Title developers and other content providers are creating an increasing array of material which includes better quality audio. Too often the limiting factor A factor or condition that, either temporarily or permanently, impedes mission accomplishment. Illustrative examples are transportation network deficiencies, lack of in-place facilities, malpositioned forces or materiel, extreme climatic conditions, distance, transit or overflight rights, has been the speakers being used to listen to these surround sound titles," commented Edward Anchel, president and chief executive officer of Altec Lansing Technologies in making this announcement. "The products covered by this new patent overcome those audio limitations while also including innovative and user-friendly designs."
Altec Lansing is already shipping surround sound computer speaker systems with technology covered by this new patent, including the ACS (Asynchronous Communications Server) See network access server. 500 and ACS400 with built-in Dolby(R) Pro-Logic and the ACS55 computer game system with Dolby(R) Surround circuitry. The ACS500, ACS400 and ACS55 also reproduce a fifth audio channel with deep bass via an external powered subwoofer A speaker that reproduces the lower end of the audio spectrum. A subwoofer system may include a crossover circuit which switches frequencies at approximately 100Hz and under to the subwoofer, while passing the rest of the signal to the main speakers. .
These products are recent results of the strategic alliance between Altec Lansing and Dolby Laboratories designed to deliver true surround sound solutions to the computer market.
Computer system manufacturers also feature audio systems based on this new patented technology as key components of their systems. Dell Computers and Gateway 2000 will feature new Altec Lansing speaker systems beginning this fall. Other Altec Lansing OEM (Original Equipment Manufacturer) The rebranding of equipment and selling it. The term initially referred to the company that made the products (the "original" manufacturer), but eventually became widely used to refer to the organization that buys the products and partners offering the company's patented surround sound audio solutions include AST (AST Computer, Irvine, CA) A PC manufacturer founded in 1980 by Albert Wong, Safi Quershey and Tom Yuen (A, S and T). It offered a complete line of PCs that sold through its dealer channel. and Fountain Technologies.
The compact size of computer screens and other video monitors are accommodated via the development of this new patented solution so that "theater-type" sound reproduction is achieved via greater audio realism for the sound accompanying a video programs. This result could not can be accomplished with conventional "music-type" stereo imaging or "virtual" surround sound approaches.
Additionally, conventional speaker systems are too bulky, expensive and heavily-wired; thus are not appropriate solutions in the computer and small home theater environments. Conventional audio speakers are also not suitable for these applications since computer users need to hear surround sound in the "near-field" environment of a PC, rather than in a large living room or other spacious listening environment.
This new invention provides a sound reproduction system via two satellite speakers designed to be placed in front of the line of sight of a viewer using a monitor. Each powered, shielded speaker enclosure has, respectively, either a right or left channel driver, center channel imaging and a side firing surround sound speaker opening. Satellites, designed by Altec Lansing under this new patent, are designed to be placed on opposite sides of a monitor.
When placed in this manner, the angles of the respective surround sound driver and speaker openings create a listening plane which surrounds the computer user with audio characterized by high intelligibility, clear articulation and enhanced effects. Delivery of surround-sound encoded material is also maximized through this newly-patented design.
In addition to the ACS500, ACS400 and ACS55 models, the company intends to develop new surround sound audio systems including hardware and software packages for the computer retail, OEM and home entertainment markets.
