Although normal microphones are very cheap, their range is usually limited up to around 10 KHz and is typically not free from various distortions. Other microphones that can reach 20 KHz or close to it typically cost tens or hundreds of dollars and still have various limitations, and higher-end microphones, for example of the types needed for Live Music performance or for the Mass media broadcasting, such as for example Radio or TV, are typically much more expensive and can cost even thousands of dollars. The main reason for these limitations is the fact that normal Microphones use a membrane, which is a mechanical element, and therefore they are limited by the mechanical qualities of the membrane. The present invention solves this problem by using a high quality Membrane-less Microphone capable of functioning in a very wide range of frequencies without distortions, which can be at the same time very compact and much cheaper than the state-of-the-art high-end microphones. This is preferably based on detecting the distortions that the detected sound waves create on preferably high frequency ultrasound waves. In some of the embodiments this microphone can also be easily made directional or even very directional, and also its directionality can preferably be easily changed dynamically, and it can be much less affected by electromagnetic interference. Similar or other principles are described also for reproducing sounds in a speaker without the physical limitations of a normal membrane.
A system for detecting sounds at a wide range of frequencies, comprising at least one beam of considerably higher frequency, which is distorted by the sound waves, so that the created distortions can be detected.
A method for detecting sounds at a wide range of frequencies, comprising the steps of:
A method in phone or cellular phone lines that are using only a limited band wherein the higher frequencies are automatically downshifted to a smaller range at the high end of the limited band, in order to lose less information.
A speaker wherein interference patterns created between at least two high frequency sources are used to create lower-frequencies and volumes desired, and at least one of the following features exists:
A speaker for reproducing sound at a wide frequency range wherein large arrays of minute membranes and/or elements are used and vibrated at all desired frequencies, with various combinations of synchronously and separately vibrating membranes.
A system for producing sounds wherein freely moveable smaller elements connected to one or more larger elements, which are vibrated by at least one transducer, are used, so that the entire bunch of elements vibrate together without having to apply a separate transducer for each of them.
A speaker wherein at least one vibrating element with free edges is used and at least one of its corners and/or edges are shaped like fractals, so that each corner can branch into additional corners in one or more planes.
A system for detecting sounds at a wide range of frequencies based on a microphone wherein instead of a membrane multiple elements are used in a hierarchical structure, based on starting with a central larger element and recursively attaching to each element smaller elements, and at least one such step of the recursion is used, and the elements are at least one of on the same plane and on more than one plane.
A system for reproducing sounds in a wide range of frequencies comprising at least one of:
