  • Publication number: 20240251199
    Abstract: An air-pulse generating device, a wearable sound device, a fanless blower, and an airflow producing method are disclosed. The air-pulse generating device includes a film structure, configured to be actuated to generate a plurality of air pulses at an ultrasonic pulse rate. The plurality of air pulses produces a net airflow toward one single direction.

  • Publication number: 20240174508
    Abstract: A wearable sound device includes a venting module, configured to form at least one vent to connect a volume within the wearable sound device and ambient, and a sound producing device, configured to produce sound according to an equalized input signal. The venting module, including at least one venting device, operates among a plurality of statuses corresponding to a plurality of degrees of opening. A controller generates the equalized input signal according to a degree of opening among the plurality of degrees of opening, in order to counteract a roll off caused by the at least one vent.

  • Patent number: 11972749
    Abstract: A wearable sound device includes a venting device including a film structure and an actuator and a driving circuit configured to be controlled by a controller and to drive the actuator, such that the film structure is controlled to form a vent or to seal the vent. The controller is coupled to a sensing device configured to generate a sensing result and determine whether to seal the vent according to the sensing result. The film structure partitions a space within the wearable sound device into a first volume and a second volume. The first volume is connected to or to be connected to an ear canal of a wearable sound device user. The second volume is connected to or to be connected to an ambient of the wearable sound device. The first volume and the second volume are connected via the vent when the vent is formed.

  • Publication number: 20210092500
    Abstract: A package structure of a sound producing device includes a base, a cap, a chip and a chamber. The cap is disposed on the base. The chip is disposed on the base, the chip includes a thin film structure and an actuator configured to actuate the thin film structure to generate a plurality of air pulses, and the cap and the chip are on a same side of the base. The chamber is formed by the base and the cap or formed by the base, the cap and the chip; the thin film structure is disposed in the chamber. One of the base or the cap has a sound outlet opening connected to the chamber, and the air pulses propagate outwards through the sound outlet opening.
