    • Various methods and apparatus for processing audio signals are disclosed herein. The assembly may be attached, adhered, or otherwise embedded into or upon a removable oral appliance to form a hearing aid assembly. Such an oral appliance may be a custom-made device which can enhance and/or optimize received audio signals for vibrational conduction to the user. Received audio signals may be processed to cancel acoustic echo such that undesired sounds received by one or more intra-buccal and/or extra-buccal microphones are eliminated or mitigated. Additionally, a multiband actuation system may be used where two or more transducers each deliver sounds within certain frequencies. Also, the assembly may also utilize the sensation of directionality via the conducted vibrations to emulate directional perception of audio signals received by the user. Another feature may include the ability to vibrationally conduct ancillary audio signals to the user along with primary audio signals.
    • 本文公开了用于处理音频信号的各种方法和装置。 组件可以附接,粘附或以其它方式嵌入到可移除的口腔器具中或之上,以形成助听器组件。 这样的口腔器具可以是可以增强和/或优化接收到的用于振动传导的用户的音频信号的定制设备。 接收的音频信号可以被处理以取消声学回声,从而消除或减轻由一个或多个颊内和/或颊外麦克风接收的不期望的声音。 此外,可以使用多频带致动系统,其中两个或更多个换能器在某些频率内传送声音。 此外,组件还可以通过传导的振动来利用方向性的感觉来模拟用户接收的音频信号的方向感知。 另一个特征可以包括将主要音频信号一起振动地向用户传导辅助音频信号的能力。

    • Microphone placement for oral applications are disclosed herein. The assembly may be attached, adhered, or otherwise embedded into or upon a removable oral appliance to form a hearing aid assembly. Such an oral appliance may be a custom-made device which can enhance and/or optimize received audio signals for vibrational conduction to the user. Received audio signals may be processed to cancel acoustic echo such that undesired sounds received by one or more intra-buccal and/or extra-buccal microphones are eliminated or mitigated. Multiple microphones may be positioned throughout the user's mouth to enhance reception of audio signals from outside sources as well as from the user's own voice. For instance, one or more microphones may be placed in contact with the inner surface of the user's cheeks to detect outside audio signals as well as in direct contact with the user's tooth or teeth to receive the user's voice through vibrational detection.
    • 本文公开了用于口头应用的麦克风放置。 组件可以附接,粘附或以其它方式嵌入到可移除的口腔器具中或之上,以形成助听器组件。 这样的口腔器具可以是可以增强和/或优化接收到的用于振动传导的用户的音频信号的定制设备。 接收的音频信号可以被处理以取消声学回声,从而消除或减轻由一个或多个颊内和/或颊外麦克风接收的不期望的声音。 可以将多个麦克风放置在用户口中,以增强从外部来源以及用户自己的声音接收音频信号。 例如,可以将一个或多个麦克风放置成与用户的脸颊的内表面接触以检测外部音频信号,以及与使用者的牙齿直接接触以通过振动检测接收用户的声音。

    • An electronic and transducer device can be attached, adhered, or otherwise embedded into or upon a removable oral appliance or other oral device to form a two-way communication assembly. In another embodiment, the device provides an electronic and transducer device that can be attached, adhered, or otherwise embedded into or upon a removable oral appliance or other oral device to form a medical tag containing patient identifiable information. Such an oral appliance may be a custom-made device fabricated from a thermal forming process utilizing a replicate model of a dental structure obtained by conventional dental impression methods. The electronic and transducer assembly may receive incoming sounds either directly or through a receiver to process and amplify the signals and transmit the processed sounds via a vibrating transducer element coupled to a tooth or other bone structure, such as the maxillary, mandibular, or palatine bone structure.
    • 电子和换能器装置可以被附接,粘附或以其它方式嵌入到可拆卸的口器具或其它口腔装置中或之上,以形成双向通信组件。 在另一个实施例中,该装置提供电子和换能器装置,其可被附接,粘附或以其它方式嵌入到可移除的口腔器具或其它口腔装置中或之上,以形成包含患者可识别信息的医疗标签。 这样的口器具可以是使用通过常规牙印模法获得的牙科结构的重复模型的热成型方法制造的定制装置。 电子和换能器组件可以直接或通过接收器接收输入声音,以处理和放大信号,并经由耦合到牙齿或其它骨结构(例如上颌骨,下颌骨或腭骨)的振动换能器元件传送经处理的声音 结构体。
