The panel 10 is deformed due to deformation of the piezoelectric element 30, and air conduction sound and human body vibration sound are transmitted to an object that is in contact with the deformed panel 10.

  • Patent number: 9560450
    Abstract: A speaker array device includes a first speaker array and a second speaker array. The first speaker array has plural first speaker units arranged in a first surface and output a first sound. The second speaker array has plural second speaker units arranged in a second surface that is different from the first surface and output a second sound. When the second speaker array and the first speaker array are installed in a room having a ceiling, the second speaker array is installed in such a manner that a normal direction to the second surface is match with a direction in which the second sound emitted from the second speaker array reaches, only indirectly, through reflection or diffraction, a sound receiving point or that the normal direction to the second surface is match with a direction in which the second sound reaches the sound receiving point with a predetermined sound volume.

  • Patent number: 9554223
    Abstract: A resilient element is used to bias a vibration element of an auditory prosthesis towards the skin of a recipient. This helps improve transmission of vibration stimuli to the recipient. Additionally, the resilient element helps reduce feedback caused by the vibration element vibrating in close proximity to sound processing components contained within the auditory prosthesis.

  • Patent number: 9439000
    Abstract: Embodiments are provided for devices for audio playback and configuring devices for audio playback. According to certain aspects, an electronic device is configured with an exterior casing that has a cutout area formed thereon. A vibrating panel is disposed within the cutout area and secured to the exterior casing such that the vibrating panel is substantially co-planar with the exterior casing. A transducer is disposed in proximity to the vibrating panel. When the transducer receives an audio signal, the transducer mechanically vibrates which causes the vibrating panel to actuate and produce audio output. The embodiments enable effective and efficient design and improve the user experience.
