Gradient micro-electro-mechanical systems (MEMS) microphone with varying height assemblies

In at least one embodiment, a micro-electro-mechanical systems (MEMS) microphone assembly is provided. The assembly comprises an enclosure, a single micro-electro-mechanical systems (MEMS) transducer,a substrate layer, and an application housing. The single MEMS transducer is positioned within the enclosure. The substrate layer supports the single MEMS transducer. The application housing supportsthe substrate layer and defining at least a portion of a first transmission mechanism to enable a first side of the single MEMS transducer to receive an audio input signal and at least a portion of asecond transmission mechanism to enable a second side of the single MEMS transducer to receive the audio input signal. 在至少一个实施方案中，提供了微机电系统(MEMS)麦克风组合件。所述组合件包括外壳、单微机电系统(MEMS)换能器、衬底层和应用壳体。所述单MEMS换能器被定位在所述外壳内。所述衬底层支撑所述单MEMS换能器。所述应用壳体支撑所述衬底层并且界定第一传输机构的至少一部分以使得所述单MEMS换能器的第一侧能够接收音频输入信号且界定第二传输机构的至少一部分以使得所述单MEMS换能器的第二侧能够接收所述音频输入信号。
