As indicated, design and construction of highly innovative miniature microphones that have far greater directionality, better sensitivity, wider frequency response, and lower noise
About
This technology consists of a miniature microphone diaphragm having a response that is highly dependent on the direction of the incident sound. The diaphragm is composed of two or more rigid diaphragm elements hinged to one another providing second- or higher-order response depending on the number of diaphragm elements used. A primary advantage of this invention over existing approaches is that this concept enables the fabrication of a single, miniature microphone diaphragm that achieves a second-order (or higher-order) directional response. This invention will lead to the development of highly innovative microphones that have far greater directionality, better sensitivity, wider frequency response, and lower noise. ADVANTAGES: As indicated, design and construction of highly innovative miniature microphones that have far greater directionality, better sensitivity, wider frequency response, and lower noise Based on the silicon microfabrication, the microphone diaphragms can be manufactured in an appropriately cost-effective manner Along with producing greatly improved devices for the hearing impaired, this technology enables the development of advanced consumer products such as directional microphones for telephones, computers, portable digital devices, and surveillance systems INTELLECTUAL PROPERTY: US 6,963,653
