    摘要: A power source of an implantable medical device (IMD) is connected to one or more components that perform various functions of the IMD via an acoustic switching circuit. The acoustic switching circuit may include one or more switches that when open disconnect the one or more components from the power source and when closed connect the one or more components to the power source to activate the one or more components. Various techniques for connecting the components to the power source are described. These techniques aim to reduce the likelihood of inadvertently connecting the power source to the one or more components in response to acoustical signals from a source of interference.
