Abstract
A mouse device includes a button switch, a microcontroller, a speaker drive circuitry and a speaker. The button switch is configured to produce a first sound when being actuated. The microcontroller is electrically coupled to the button switch. The button switch is configured to provide an actuation signal to the microcontroller when being actuated. The speaker drive circuitry is electrically coupled to the microcontroller and the speaker is electrically coupled to the speaker drive circuitry. The speaker drive circuitry is configured to drive the speaker to play a second sound that substantially cancels out the first sound.
Claims8
A mouse device, comprising:
- a button switch configured to produce a first sound when being actuated;
- a microcontroller electrically coupled to the button switch, wherein the button switch is configured to provide an actuation signal to the microcontroller when being actuated;
- a speaker drive circuitry electrically coupled to the microcontroller;
- a speaker electrically coupled to the speaker drive circuitry, wherein the speaker drive circuitry is configured to drive the speaker to play a second sound that substantially cancels out the first sound;
- an audio recording device configured to record the first sound as a first audio signal in response to the microcontroller receiving the actuation signal from the button switch;
- and
- a signal processing unit configured to compute a second audio signal based on the first audio signal, wherein the second audio signal is associated with the second sound.
A noise cancellation method for a mouse device, the mouse device comprising a button switch, a microcontroller, an audio recording device and a speaker, the button switch configured to produce a first sound when being actuated, the noise cancellation method comprising:
- instructing the audio recording device to record the first sound as a first audio signal in response to the microcontroller receiving an actuation signal from the button switch;
- computing a second audio signal based on the first audio signal;
- and
- instructing the speaker to play a second sound based on the second audio signal when the button switch is actuated, the second sound substantially cancelling out the first sound.
