Abstract
A piezoelectric speaker is disclosed, comprising an elastic base, a piezoelectric material bender, and an acoustical linkage mounted to both the elastic base and the bender and serving to interconnect the elastic base and the bender. The acoustical linkage is fabricated from a rigid material and is mounted to the bender at approximately the geometric center of the bender. The bender may also be encapsulated by a case. The elastic base may include a computer keyboard, a bicycle helmet, a pen, a desk, a computer monitor or any other similar structure.
Claims54
A speaker comprising:
- a structure capable of emitting sound when vibrated, said structure having an existing primary purpose other than to emit sound;
- and
- a piezodriver coupled to said structure at a single point of coupling in a manner causing said piezodriver to be offset from the structure and causing vibrational mechanical energy from said piezodriver to propagate into said structure and produce therefrom audible sound so as to provide a secondary purpose for said structure, said secondary purpose being that the structure itself acts as a speaker.
A speaker comprising:
- a structure capable of emitting sound when vibrated, said structure having an internal cavity, and said structure having an existing primary purpose other than to emit sound;
- and
- a piezodriver housed within said internal cavity, said piezodriver having an impedance substantially matched with the mechanical impedance of said structure and coupled to said structure at a single point of coupling in a manner causing said piezodriver to be offset from the structure and causing vibrational mechanical energy from said piezodriver to propagate into said structure and produce therefrom audible sound so as to provide a secondary purpose for said structure, said secondary purpose being that the structure itself acts as a speaker.
A speaker comprising:
- a structure capable of emitting sound when vibrated, said structure having an existing primary purpose other than to emit sound;
- and
- a piezodriver to vibrate comprising piezoelectric material bonded to a shim, said shim having a portion that extends beyond said piezoelectric material and is rigidly attached to said structure so that the piezoelectric material and shim portion bonded together is offset from said structure, wherein vibrational mechanical energy from said piezodriver propagates into said structure and produces therefrom audible sound so as to provide a secondary purpose for said structure, said secondary purpose being that the structure itself emits sound as the speaker.
A speaker comprising:
- a piezodriver including ends to vibrate;
- a structure having an existing primary commercial purpose other than to produce sound, said structure having an internal cavity, and said structure having an integrally molded mounting stud rigidly coupled with said piezodriver in a manner which elevates said piezodriver off the structure so that said ends are fine to vibrate causing vibrational mechanical energy from said piezodriver to propagate into said structure and produce therefrom audible sound so as to provide a secondary purpose for said structure, said secondary purpose being that the structure itself acts as a speaker.
A speaker comprising:
- a structure having an existing pi commercial purpose other than to produce sound, said structure having sound producing qualities when vibrated;
- a piezodriver having an impedance substantially matched with the mechanical impedance of said structure;
- and
- an interconnection mechanism of rigid material rigidly interconnecting said structure and said piezodriver, said interconnection mechanism causing vibrational mechanical energy of the piezodriver to be propagated into the structure and produce therefrom audible sound so as to provide a secondary purpose for said structure, said secondary purpose being that the structure itself acts as a speaker.
1 more element
A speaker comprising:
- a structure having an existing primary commercial purpose other than to produce sound, said structure having an internal cavity, and said structure having sound producing qualities when vibrated;
- a piezodriver to vibrate, said piezodriver coupled to said structure and housed within said internal cavity;
- and
- an interconnection mechanism of rigid material rigidly interconnecting said structure and said piezodriver wherein the mechanical impedance of the structure is substantially matched with the piezodriver impedance, said rigid material having at least one end for coupling to the piezodriver and at least one other end for coupling to the structure wherein one or more of said at least one end or said at least one other end is flared, said rigid material causing vibrational mechanical energy of the piezodriver to be propagated into the structure and produce therefrom audible sound so as to provide a secondary purpose for said structure, said secondary purpose being that the structure itself acts as a speaker.

A speaker comprising:
- a suture capable of emitting sound when vibrated, said structure having an existing primary purpose other than to emit sound;
- and
- two piezodrivers in a spaced apart relationship, one on top of another, coupled to said structure using an acoustical linkage and in a manner causing said piezodrivers to be offset from the structure and causing vibrational mechanical energy from said piezodrivers to propagate into said structure and produce therefrom audible sound so as to provide a secondary purpose for said structure, said secondary purpose being that the structure itself acts as a speaker.
The speaker of clam 49, wherein:
- said piezodriver has an impedance substantially matched with the mechanical impedance of said structure.
