Title:
AIR-PULSE GENERATING DEVICE AND SOUND PRODUCING METHOD THEREOF
Document Type and Number:
Japanese Patent JP2022160366
Kind Code:
A
Abstract:
To provide an air-pulse generating device.SOLUTION: An air-pulse generating device includes a membrane structure, a valve structure, and a cover structure. A chamber is formed between the membrane structure, the valve structure and the cover structure. An air wave vibrating at an operating frequency is formed within the chamber. The valve structure is configured to be actuated to perform an open-and-close movement to form at least one opening. The at least one opening connects air inside the chamber with air outside the chamber. The open-and-close movement is synchronous with the operating frequency.SELECTED DRAWING: Figure 1
