Abstract
An air pulse generating element, disposed in a sound producing device, includes a membrane, disposed within a chamber; and a plurality of valves, disposed by the membrane within the chamber, configured to seal a plurality of openings of the chamber in response to a plurality of valve control signals; wherein the membrane and the plurality of valves are all fabricated at a first layer.
Claims18
An air pulse generating element, disposed in a sound producing device, comprising:
- a membrane, disposed within a chamber;
- and a plurality of valves, disposed by the membrane within the chamber, configured to seal a plurality of openings of the chamber in response to a plurality of valve control signals, wherein the plurality of valves comprises
- a first valve, configured to seal a first opening of the chamber in response to a first valve control signal, wherein the first opening is formed on a first faceplate of the air pulse generating element, and the first faceplate is disposed at a second layer;
- a second valve, configured to seal a second opening of the chamber in response to a second valve control signal, wherein the second opening is formed on a second faceplate of the air pulse generating element, and the second faceplate is disposed at a third layer,
- a third valve, configured to seal a third opening of the chamber in response to a third valve control signal, wherein the third opening is formed on the first faceplate;
- and
- a fourth valve, configured to seal a fourth opening of the chamber in response to a fourth valve control signal, wherein the fourth opening is formed on the second faceplate of the air pulse generating element;
- wherein the membrane and the plurality of valves are all fabricated at a first layer.
