    • A hearing aid having two physically separate receivers, one for outputting low frequency (LF) acoustic sounds and another for outputting high frequency (HF) acoustic sounds. The LF receiver's output port is connected to a tube in which the HF receiver is inserted. The LF acoustic sounds either flow around the HF receiver, which include standoffs to space the HF receiver away from the inner tube wall, or through a channel in the HF receiver. At the output of the HF receiver, the LF and HF acoustic sounds are combined to form an acoustic signal that is transmitted to the ear canal. The LF receiver can be optimized for compliance, distortion, resonance frequency, and output. Its orientation is selected for reducing the overall size of the hearing aid. The HF receiver is smaller and placed far away from any microphone(s), reducing feedback effects, and may have a cylindrical or rectangular shape.
    • 助听器具有两个物理分离的接收器,一个用于输出低频(LF)声音,另一个用于输出高频(HF)声音。 LF接收器的输出端口连接到HF接收器插入的管中。 LF声音可以在HF接收器周围流动,HF接收器包括用于将HF接收器远离内管壁或通过HF接收器中的通道放置的间隔。 在HF接收机的输出处,LF和HF声音被组合以形成传输到耳道的声信号。 LF接收机可以针对兼容性,失真,共振频率和输出进行优化。 选择其方向以减小助听器的总体尺寸。 HF接收器较小,放置在远离任何麦克风的位置,减少了反馈效应,并且可能具有圆柱形或矩形形状。

    • A microphone assembly comprising a housing in which a transducer element is positioned. In the housing, an upper and a lower chamber are defined, the lower chamber extending at least at one edge of the transducer element and potentially to an upper side thereof. An element, such as a horse-shoe shaped element or a circular element, is provided for separating the upper side of the transducer element into the upper and lower chambers. The transducer element is fixed using flexible fixing means, and space is provided at one or more sides of the transducer element to take up thermal expansion and retraction of the housing and the transducer element.
    • 麦克风组件,其包括壳体,换能器元件定位在该壳体中。 在壳体中,限定了上腔室和下腔室,下腔室至少在换能器元件的一个边缘延伸并且潜在地延伸到其上侧。 提供诸如马蹄形元件或圆形元件的元件,用于将换能器元件的上侧分离成上部和下部腔室。 换能器元件使用柔性固定装置固定,并且在换能器元件的一侧或多侧设置空间以吸收壳体和换能器元件的热膨胀和收缩。
