  • Patent number: 11501748
    Abstract: A first cancellation signal output from a first speaker cancels noise at a first cancellation point, which is a typical position of the right ear of a user, together with a second cancellation signal output from a second speaker. In addition, the second cancellation signal output from the second speaker cancels noise at a second cancellation point, which is a typical position of the left ear of the user, together with the first cancellation signal output from the first speaker. The first speaker and the second speaker are arranged side by side on a second line segment, which passes through the midpoint of a first line segment connecting the first cancellation point and the second cancellation point to each other and is perpendicular to the first line segment, and a range where the relationship between noise and the first cancellation signal and the second cancellation signal is the same as that at the cancellation point is extended.

  • Patent number: 11340726
    Abstract: In a first state before a first event is detected, a determination unit of a press detection apparatus prevents a definitive value from increasing steeply when the pressing force has increased steeply, and decreases the definitive value steeply when the pressing force has decreased steeply. In a second state after the first event is detected and before a second event is detected, the determination unit prevents the definitive value from increasing steeply when the pressing force has increased steeply, and prevents the definitive value from decreasing steeply when the pressing force has decreased steeply. This reduces the possibility that the definitive value increases steeply in the first state and increases and decreases steeply in the second state even under vibration.

  • Patent number: 11335314
    Abstract: Adaptive filters output a cancellation sound from a speaker, a selector selects outputs of a plurality of auxiliary filters each corresponding to different positions, a subtractor subtracts the selected output from the output of the microphone and outputs the subtracted output to the adaptive filter as an error signal, and a position detection device detects a position of a head of a user. A transfer function estimated so that the error signal becomes 0 when noise is canceled at the corresponding position is preset in the auxiliary filter. When the auxiliary filter corresponding to the position close to the head of the user changes, the switching control unit stepwise increases the frequency with which the output of the auxiliary filter is selected by the selector to 100%.

  • Patent number: 11294487
    Abstract: The present invention includes a touch time detection unit detecting a touch time on an operation unit and a determination controller changing content of a determination process to be performed by a pressing operation determination unit based on the touch time. Content of the determination process to be performed by the pressing operation determination unit based on a pressing amount is changed such that the ease of detection of a pressing operation when a pressing amount is instantaneously changed in a short period of time is changed based on a touch time so that false detection of a pressing operation caused by an instantaneous change of a pressing amount due to noise in a pressing operation of gradually increasing pressure is avoided and a case where a pressing operation of performing a strong press in a short period of time is not detected is avoided.
