摘要： Systems, devices, and methods related to a Deep Learning Accelerator and memory are described. For example, a microphone may be configured to execute instructions with matrix operands and configured with: a transducer to convert sound waves to electrical signals; an analog to digital converter to generate audio data according to the electrical signals; random access memory to store instructions executable by the Deep Learning Accelerator and store matrices of an Artificial Neural Network; and a controller to store the audio data in the random access memory as an input to the Artificial Neural Network. The Deep Learning Accelerator can execute the instructions to generate an output of the Artificial Neural Network, which may be provided as the primary output of the microphone to a computer system, such as a voice-based digital assistant.

摘要： A microelectromechanical system (MEMS) transducer includes a transducer substrate including an opening; a back plate including a plurality of protrusions oriented substantially perpendicular to the back plate; and a diaphragm between the transducer substrate and the back plate. The diaphragm includes a lead and a plurality of spring members. The lead is structured to suspend the diaphragm over the transducer substrate. The spring members are structured to separate the diaphragm from the transducer substrate and the back plate in the absence of a bias voltage.

摘要： The present invention discloses a microphone module. The module comprises: a housing having a sound receiving hole; a pressing plate fixedly combined with the housing, an accommodating cavity being formed between the inner side surface of the pressing plate and the outer side surface of the housing, and the pressing plate comprising sound transmitting hole corresponding to the sound receiving hole; and an intermediate layer covering the sound receiving hole, provided on the outer or inner side surface of the housing, and corresponding to the sound receiving hole. The housing further comprises an annular protrusion having a passage, extending outwards from the outer side surface of the housing, and surrounding the sound receiving hole. According to the microphone module provided in the present invention, by combining the sound transmitting hole with the annular protrusion having the passage, the vibration amplitude of the intermediate layer remains small even when the microphone module is subjected to high-pressure water impact, such that deformation and breaking of the intermediate layer are avoided. Therefore, the influence on the acoustic performance and waterproof performance of the microphone module is reduced.

摘要： A microelectromechanical systems (MEMS) die includes a substrate, a back plate, and a diaphragm. The back plate is coupled to the substrate and includes a dielectric layer and an electrode. The electrode is coupled to the dielectric layer and defines an opening that exposes a central portion of the dielectric layer. The diaphragm is oriented parallel to the back plate and is spaced apart from the back plate. In one implementation, a diameter of the opening is greater than or equal to 1/10 of the diameter of the diaphragm.

摘要： A microphone assembly comprises a substrate and an enclosure disposed on the substrate. A port is defined in one of the substrate or the enclosure. An acoustic transducer is configured to generate an electrical signal in response to acoustic activity. The acoustic transducer comprises a membrane separating a front volume from a back volume of the microphone assembly. The front volume is in fluidic communication with the port, and the back volume is filled with a first gas having a thermal conductivity lower than a thermal conductivity of air. An integrated circuit is electrically coupled to the acoustic transducer and configured to receive the electrical signal from the acoustic transducer. At least a portion of a boundary defining at least one of the front volume or the back volume is configured to have compliance so as to allow pressure equalization. The first gas is different from the second gas.

摘要： A distribution assistance apparatus and a distribution assistance method are provided. An input and output IF mixes a sound input from an HS microphone or a built-in microphone with a sound signal of distribution data received from a portable terminal and outputs the sound. Even when an addition process or an effect is applied to distribution data in the portable terminal, a sound input from the HS microphone or the built-in microphone can be output through a monitor at that point in time without causing a latency.

摘要： In one example, a video endpoint obtains, from a vertical microphone array, a first audio signal including audio from a target sound source and audio from a horizontally-displaced sound source. The video endpoint obtains, from a horizontal microphone array, a second audio signal and a third audio signal both including the audio from the target sound source and the audio from the horizontally-displaced sound source. Based on the second audio signal and the third audio signal, the video endpoint determines at least one of a first degree of arrival of the audio from the target sound source or a second degree of arrival of the audio from the horizontally-displaced sound source. Based on the at least one of the first degree of arrival or the second degree of arrival, the video endpoint adjusts a gain of the first audio signal.
