    • Systems and methods for a bone-conduction transducer array configured to provide spatial audio are described, in which the bone-conduction transducer array may be coupled to a head-mountable device so as to provide sound, for example, to a wearer of the head-mountable device. Audio information and a vibration transducer from an array of vibration transducers coupled to the head-mountable computing device may be caused to vibrate based at least in part on the audio signal so as to transmit a sound. Information indicating a movement of the wearable computing device toward a given direction may be received. One or more parameters associated with causing the at least one vibration transducer to emulate the sound from the given direction may then be determined, wherein the one or more parameters are representative of a correlation between the audio information and the information indicating the movement.
    • 描述了构造成提供空间音频的骨传导换能器阵列的系统和方法,其中骨传导换能器阵列可以耦合到可头戴式装置,以便例如提供头部佩戴者的声音 可装置的装置。 可以使耦合到头戴式计算设备的振动换能器阵列的音频信息和振动传感器至少部分地基于音频信号进行振动,从而传输声音。 可以接收指示可穿戴计算设备朝向给定方向的移动的信息。 然后可以确定与使至少一个振动换能器从给定方向模拟声音相关联的一个或多个参数,其中所述一个或多个参数表示音频信息和指示移动的信息之间的相关性。

    • A thin film bone-conduction transducer for a head-mountable device is provided. In one example, the head-mountable device may include a head-mountable display that is configured to provide bone-conduction audio using one or more bone-conduction transducers. The head-mountable display may include at least one thin film piezoelectric vibration transducer that is configured to vibrate at least a portion of the head-mountable display based on the audio signal. The vibration transducer may be at least partially enclosed in, fully enclosed between, or a portion of an outer surface of the frame of the head-mountable display such that when the head-mountable display is worn, the head-mountable display contacts one or more surfaces of the wearer's head and provides information indicative of the audio signal to the wearer via vibration of a bone structure of the wearer.
    • 提供了一种用于头戴式装置的薄膜骨传导换能器。 在一个示例中,头戴式装置可以包括头戴式显示器,其被配置为使用一个或多个骨传导换能器来提供骨传导音频。 可头戴式显示器可以包括至少一个薄膜压电振动换能器,其配置成基于音频信号振动可头戴式显示器的至少一部分。 振动传感器可以至少部分地封装在完全封闭在头戴式显示器的框架的外表面之间或其一部分之后,使得当可头戴式显示器被磨损时,可头戴式显示器接触一个或 穿戴者头部的更多表面,并且通过穿戴者的骨骼结构的振动向佩戴者提供指示音频信号的信息。
