摘要： A venting device includes an anchor structure and a membrane. The membrane is anchored on the anchor structure and configured to form a first vent and a second vent. The membrane includes a first flap, a second flap and a third flap. The membrane partitions a space into a first volume and a second volume, and the first volume and the second volume are connected when the first vent and the second vent are formed. The first flap is actuated to move toward a first direction and the second flap is actuated to move toward a second direction opposite to the first direction, so as to form the first vent. The first flap is actuated to move toward the first direction and the third flap is actuated to move toward the second direction opposite to the first direction, so as to form the second vent.

摘要： 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.

摘要： An acoustic transducer is configured to perform an acoustic transformation. The acoustic transducer is disposed within a wearable sound device or to be disposed within the wearable sound device. The acoustic transducer includes at least one anchor structure, a film structure and an actuator. The film structure is disposed within a first layer and anchored by the anchor structure disposed within a second layer. The actuator is disposed on the film structure, and the actuator is configured to actuate the film structure to form a vent temporarily. The film structure partitions a space into a first volume to be connected to an ear canal of a wearable sound device user and a second volume to be connected to an ambient of the wearable sound device. The ear canal and the ambient are to be connected via the vent temporarily opened when the film structure is actuated.

摘要： A sound producing device includes a first sound producing cell, driven by a first driving signal and configured to produce a first acoustic sound on a first audio band, and a second sound producing cell, driven by a second driving signal and configured to produce a second acoustic sound on a second audio band different from the first audio band. A first membrane of the first sound producing cell and a second membrane of the second sound producing cell are Micro Electro Mechanical System fabricated membranes. The first audio band is upper bounded by a first maximum frequency; the second audio band is upper bounded by a second maximum frequency. A first resonance frequency of the first membrane is higher than the first maximum frequency of the first driving signal. A second resonance frequency of the second membrane is higher than the second maximum frequency of the second driving signal.

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.
