    摘要： An acoustic device includes a first sound producing component and a back cavity structure. The first sound producing component has a first front side and a first back side, wherein the first sound producing component is a high frequency sound unit, and the first front side faces a sound propagating opening of the acoustic device. The back cavity structure is connected to the first back side of the first sound producing component. The first sound producing component produces a first acoustic wave from the first front side towards the sound propagating opening, and the first sound producing component produces a second acoustic wave from the first back side towards a back cavity of the back cavity structure. The back cavity structure is configured to flatten a peak or a dip of a frequency response of the first sound producing component.

    摘要： A driving circuit, configured to drive a venting device, includes a first node, a second node, and an amplifying circuit. The venting device, configured to be controlled to open a vent or seal the vent, includes a film structure, which includes a first flap and a second flap, and an actuator, which includes a first actuating portion disposed on the first flap and a second actuating portion disposed on the second flap. When the venting device is controlled to open the vent, the driving circuit generates a first voltage at the first node and generates a second voltage at the second node. When the venting device is controlled to seal the vent, the driving circuit generates a third voltage at both the first node and the second node. The first voltage is larger than the third voltage, and the third voltage is larger than the second voltage.

    摘要： A manufacturing method for a device includes: providing a wafer including a first layer and a second layer; forming and patterning an actuating material formed on the wafer; patterning the first layer of the wafer to form a trench line; and removing a first part of the second layer. The first layer forms a film structure including a membrane. A slit is formed within and penetrates through the membrane because of the trench line. The film structure is actuated to form a vent temporarily because of the slit. An ear canal and an ambient of a wearable sound device are to be connected via the vent temporarily opened. The slit divides the membrane into a first membrane portion and a second membrane portion. A difference between the displacements of these two membrane portions is larger than a thickness of the membrane when the vent is formed.

    摘要： A method for manufacturing an air pulse generating element is provided. First, a thin film layer including a membrane is provided, and then, a plurality of actuators are formed on the thin film layer. After that, a first chamber is formed between the thin film layer and a first plate and followed by patterning the thin film layer to form a plurality of valves, in which the membrane and the valves are formed of the thin film layer. Subsequently, a second chamber is formed between the thin film layer and a second plate, and a plurality of channels are formed in the first plate and the second plate.

    摘要： A venting device includes a first flap, which is configured to be actuated to swing upward during a rising time, and a second flap, which is disposed opposite to the first flap and configured to be actuated to swing downward during a falling time, a first actuating portion disposed on the first flap, and a second actuating portion disposed on the second flap. The venting device configured to form a vent is disposed within a wearable sound device or to be disposed within the wearable sound device. The vent is formed via applying a first voltage to the first actuating portion and applying a second voltage on the second actuating portion, such that the venting device gradually forms the vent.
