==SIMULTANEOUS DUAL USE OF AN ACOUSTIC DEVICE AS A LOUDSPEAKER AND MICROPHONE - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240305930 titled 'SIMULTANEOUS DUAL USE OF AN ACOUSTIC DEVICE AS A LOUDSPEAKER AND MICROPHONE

The abstract describes a patent application for operating an electrostatic acoustic device as both a speaker and a microphone. The device includes a membrane and an electrode, with an input audio signal causing the membrane to respond mechanically to a varying electric field. A portion of the input signal is tapped to produce a reference signal, which is compared to the output signal generated by detecting motion of the membrane. This process results in a microphone signal responsive to ambient sound pressure variations.

* The electrostatic acoustic device functions as both a speaker and a microphone.
* It includes a membrane and an electrode for converting audio signals into mechanical responses.
* A reference signal is produced by tapping a portion of the input audio signal.
* Motion of the membrane is detected to generate an output signal, which is compared to the reference signal to produce a microphone signal.
* The microphone signal captures ambient sound pressure variations.

==Original Abstract Submitted==

operating an electrostatic acoustic device simultaneously as a speaker and as a microphone. the electrostatic acoustic device includes a membrane and an electrode disposed proximate to the membrane. an input varying audio signal is input to the electrostatic acoustic device. the membrane is configured to respond mechanically to a varying electric field responsive to the varying audio signal input. a portion of the input varying audio signal is tapped to produce a reference signal. a signal is detected responsive to motion of the membrane, to convert the signal to an output varying voltage signal. the output varying voltage signal is compared to the reference signal to produce a microphone signal. the microphone signal is responsive to motion of the membrane induced by air pressure variations of ambient sound.
