Abstract
A flow controlled sound generation system is disclosed that includes one or more fluid pumps to control air flow through a sound channel. The air flow is modulated through one or more valves to produce audible frequency pressure waves.
Claims22
A sound generation system comprising:
- a controller;
- a first fluid pump to produce an air flow through a sound channel;
- and
- a sound control medium disposed within the sound channel, the sound control medium to modulate the air flow to produce pressure waves at a plurality of audible frequencies.
1 more element
A sound generation apparatus comprising:
- a bidirectional array including a first sheet array and a second sheet array, the first and second sheet arrays each including an anchored end and a floating end;
- a first oscillatory driver coupled to the anchored end of the first sheet array, the first oscillatory driver to operate the first sheet array in order to produce an air flow in a first direction;
- a second oscillatory driver coupled to the anchored end of the second sheet array, the second oscillatory driver to operate the second sheet array in order to produce an air flow in a second direction;
- a controller coupled to the first oscillatory driver and the second oscillatory driver, the controller to dynamically control the first oscillatory driver and the second oscillatory driver to produce amplitude and/or frequency modulated pressure pulses.
