Patent number: 11172312Abstract: The present disclosure relates generally to a microphone assembly. The microphone assembly has an acoustic activity detection mode of operation when the electrical circuit is clocked using an internal clock signal generator in the absence of an external clock signal at a host interface, and an electrical circuit of the microphone assembly is configured to provide an interrupt signal to the host interface upon detection of acoustic activity by the electrical circuit. The electrical circuit is configured to control the operating mode of the microphone assembly based on a frequency of the external clock signal in response to providing the interrupt signal and is configured to provide data representing the electrical signal to the host interface using the external clock signal received at the host interface.Type: GrantFiled: January 26, 2020Date of Patent: November 9, 2021Assignee: Knowles Electronics, LLCInventors: Claus Erdmann Fürst, Henrik Thomsen, Michael Deruginsky, Dibyendu Nandy, Oddy Nopporn Khamharn, Aziz Yurttas, Svetoslav Radoslavov Gueorguiev, Anders Mortensen

Patent number: 10313796Abstract: A microphone assembly includes an acoustic sensor configured to produce an electrical signal and an electrical circuit including a voice activity detector coupled to an output of the acoustic sensor. The microphone assembly further includes an internal clock signal generator and a host interface coupled to the electrical circuit. The host interface has external connections including an external clock signal and a data connection. The microphone assembly includes an acoustic activity detection mode of operation when the electrical circuit is clocked by the internal clock signal generator in the absence of an external clock signal at the host interface. The microphone assembly has a plurality of operating modes controlled by an external clock signal received in response to an interrupt signal provided by the electrical circuit. The electrical circuit is configured to provide data representing the electrical signal at the host interface when the external clock signal is received.Type: GrantFiled: August 12, 2015Date of Patent: June 4, 2019Assignee: Knowles Electronics, LLCInventors: Claus Erdmann Fürst, Henrik Thomsen, Michael Deruginsky, Dibyendu Nandy, Oddy Nopporn Khamharn

Patent number: 9712923Abstract: A microphone includes a microelectromechanical system (MEMS) circuit and an integrated circuit. The MEMS circuit is configured to convert a voice signal into an electrical signal, and the integrated circuit is coupled to the MEMS circuit and is configured to receive the electrical signal. The integrated circuit and the MEMS circuit receive a clock signal from an external host. The clock signal is effective to cause the MEMS circuit and integrated circuit to operate in full system operation mode during a first time period and in a voice activity mode of operation during a second time period. The voice activity mode has a first power consumption and the full system operation mode has a second power consumption. The first power consumption is less than the second power consumption. The integrated circuit is configured to generate an interrupt upon the detection of voice activity, and send the interrupt to the host.Type: GrantFiled: May 20, 2014Date of Patent: July 18, 2017Assignee: Knowles Electronics, LLCInventors: Claus Erdmann Fürst, Henrik Thomsen, Michael Deruginsky, Dibyendu Nandy, Oddy Nopporn Khamharn
