Abstract
An electroacoustic novelty, particularly to the brim on an article of headware, or to a flag, containing a piezoelectric polymer film, where means are electrically coupled with electrodes on the film for applying an audio-frequency signal voltage across the film to cause the film to vibrate and emit sound waves.
Claims16
An electroacoustic novelty, comprising:
- a flexible substrate forming at least a portion of said novelty, at least a portion of said substrate having a curved, noncontinuous cross section;
- a piezoelectric polymer film having opposed first and second surfaces;
- a first transparent electrode electrically coupled with said first surface;
- a second transparent electrode electrically coupled with said second surface;
- means for conformably adhering said film to the portion of said substrate having the curved, noncontinuous cross section;
- and
- means electrically coupled with said first and second electrodes for applying an audio-frequency signal voltage across said film to cause said film and associated portion of said substrate having the curved, noncontinuous cross section to vibrate and emit sound waves.

An electroacoustic brim on an article of headwear, comprising:
- a flexible substrate forming at least a portion of said brim, at least a portion of said substrate having a curved, noncontinuous cross section;
- a piezoelectric polymer film having opposed first and second surfaces which responds to received sound waves by vibrating with said substrate and producing an electrical audio signal;
- a first electrode electrically coupled with said first surface;
- a second electrode electrically coupled with said second surface;
- a device responsive to processed electrical audio signals;
- means for conformably adhering said film to the portion of said substrate having the curved, noncontinuous cross section;
- and
- receiving means electrically coupled with said first and second electrodes for processing the electrical audio signal generated by said film when said film is caused to vibrate by sound waves and delivering the processed electrical audio signal to said device.
5 more elements
An electroacoustic brim of an article of headwear, comprising:
- a piezoelectric polymer film having a curved, noncontinuous cross section forming at least a portion of said brim, said film having first and second opposed surfaces;
- a first electrode electrically coupled with said first surface;
- a second electrode electrically coupled with said second surface;
- and
- means electrically coupled with said first and second electrodes for applying an audio-frequency signal voltage across said film to cause said film to vibrate and emit sound waves.
2 more elements
An electroacoustic article of headwear with auto-frequency transducer, wherein said headwear is provided with a brim, comprising:
- a piezoelectric polymer film having a curved, noncontinuous cross section forming at least a portion of said brim, said film having first and second opposed surfaces and responding to processed electrical signals by vibrating and producing sound waves;
- a first electrode electrically coupled with said first surface;
- a second electrode electrically coupled with said second surface;
- and
- receiving means electrically coupled with said first and second electrodes for processing electrical signals which are then delivered to said film to cause said film to vibrate and produce sound waves.
2 more elements
