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.
Claims16
A sound generation system comprising:
- a controller;
- a first fluid pump to produce a continuous and direct 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;
- wherein the sound control medium comprises a first grating disposed within the sound channel, the first grating having a first micro-valve array disposed on a plurality of openings of the first grating, wherein micro-valves of the first micro-valve array are configured to operate in unison to collectively manipulate the air flow to produce pressure waves at a plurality of audible frequencies.
