US Patent 11984133 Operation device

Disclosed is an operation device including an interaction member, a microphone, a control circuit, and an audio signal processing circuit. The interaction member is used for interacting with a user. The control circuit periodically acquires scan data indicating the acting status of the interaction member. The audio signal processing circuit executes a noise removal process of removing noise from a collected audio signal collected by the microphone. The control circuit periodically transmits previously acquired scan data to the audio signal processing circuit. The audio signal processing circuit executes the noise removal process by using the scan data transmitted from the control circuit.
