Abstract
An acoustic diaphragm is disclosed having a plurality of acoustic elements supported by the diaphragm. In a preferred form, each element is coupled to a driver and extends radially at a uniform acute angle to a normal of the driver. In the preferred embodiment, a plural layer of the elements is arranged so that the direction of each element is out-of-phase relative to each other, preferably in the range of approximately ninety degree. An element is also supplemental to the conventional acoustic diaphragm. The improved acoustic diaphragm is used in electric acoustic and acoustic electric transducer systems having improved performance at wide frequency range.
Claims36
An acoustic diaphragm for communication of acoustic energy comprising:
- an acoustic diaphragm coupled to a driver;
- and
- a plurality of continuous and solid acoustic elements supported by said acoustic diaphragm, each of said acoustic elements having a proximate end coupled to said driver, and extending radially therefrom at an acute angle between zero and ninety degrees to a normal with respect to said driver and on a surface with respect to said acoustic diaphragm;
- wherein said plurality of acoustic elements are oriented in a selected stiffness pattern surrounding said driver without knitting or weaving said acoustic elements, wherein at least one of said plurality of acoustic elements has a portion which is not straight.
An audio speaker comprising:
- an acoustic diaphragm coupled to a driver;
- and
- a plurality of continuous and solid acoustic elements supported by said acoustic diaphragm, each of said acoustic elements having a proximate end coupled to said driver, and extending radially therefrom at an acute angle between zero and ninety degrees to a normal with respect to said driver and on a surface with respect to said acoustic diaphragm;
- and
- wherein said plurality of acoustic elements are oriented in a selected stiffness pattern surrounding said driver without knitting or weaving said acoustic element, wherein at least one of said plurality of acoustic elements has a portion which is not straight.
An audio microphone comprising:
- an acoustic diaphragm coupled to a driver;
- and
- a plurality of continuous and solid acoustic elements supported by said acoustic diaphragm, each of said acoustic elements having a proximate end coupled to said driver, and extending radially therefrom at an acute angle between zero and ninety degrees to a normal with respect to said driver and on a surface with respect to said acoustic diaphragm;
- and
- wherein said plurality of acoustic elements are oriented in a selected stiffness pattern surrounding said driver without knitting or weaving said acoustic element, wherein at least one of said plurality of acoustic elements has a portion which is not straight.
An acoustic diaphragm comprising,
- a vibratory member comprising a plurality of elements formed from a plane drive system;
- an electric exciting means adapted to an acoustic diaphragm to cause each said element to vibrate when said electric exciting means is energized;
- wherein said each element has a proximate end coupled to a central portion of said acoustic diaphragm and extending radially at a uniform acute angle between zero and ninety degrees to a normal of said central portion of said acoustic diaphragm.
