Abstract: An electronic device is provided for receiving sounds from a body. A microphone array receives the sounds. An analysis system optionally provides for directional control, such as by providing virtual focusing and beam steering. Body sounds are preferably de-convolved. In certain embodiments, a plurality of buffer structures are located in cavities in a patch adjacent the microphones to provide for improved sound pick-up. In certain embodiments, at least two of microphones are spaced at least 2 centimeters apart. Preferably, wireless transmission circuitry sends information relating to the sounds in the body, and optionally receives information, such as control or status information. Target selection and acquisition systems provide for the effective capture of multiple sounds from the body, even when the device is adhered to the body by the user, that is, not a skilled physician.

Abstract translation: 提供一种用于从身体接收声音的电子设备。 麦克风阵列接收声音。 分析系统可选地提供方向控制，例如通过提供虚拟聚焦和波束转向。 身体声音最好是去卷积的。 在某些实施例中，多个缓冲结构位于与麦克风相邻的贴片中的空腔中，以提供改进的拾音。 在某些实施例中，至少两个麦克风间隔开至少2厘米。 优选地，无线传输电路发送与身体中的声音有关的信息，并且可选地接收诸如控制或状态信息的信息。 目标选择和采集系统即使当设备被用户粘附到身体上时，即不是熟练的医生，也能够有效地捕获来自身体的多个声音。
