Abstract: Disclosed is a wrist-worn device and air pressure adjustment method, apparatus and system thereof. The method includes: controlling a speaker of the wrist-worn device to emit a first sound (S110); receiving a sound signal picked up by a microphone, and analyzing the sound signal to obtain a corresponding amplitude value (S120); and determining whether the amplitude value is less than a preset amplitude threshold (S130), and if so, performing pressure relief process of a rear cavity of the speaker, so that the rear cavity of the speaker maintains air pressure balance (S140), thereby ensuring that the speaker can operate normally, and is advantageous in improving the user experience.

Abstract: An acoustic input apparatus, an acoustic input apparatus, an electronic device, and a computer-readable medium. A first acoustic source is configured to generate a first acoustic wave, in response to a user performing a first operation. An acoustic transducer is configured to collect an acoustic wave and convert the collected acoustic wave into an electrical signal reflecting a frequency of the collected acoustic wave. The comparing circuit is configured to receive the electrical signal, determine whether the collected acoustic wave includes the first acoustic wave based on whether the frequency meets a first preset condition, and output an operating signal. The operating signal is in a first state in response to the collected acoustic wave including the first acoustic wave. The technical solution simplifies wiring and improves robustness to electromagnetic environment, while ensuring accuracy for recognizing an input of the user.

Abstract: A gamepad and a joystick feedback force apparatus thereof are disclosed. The joystick feedback force apparatus comprises a joystick that is configured to accept a user's operation and is rotatably installed in a casing of the gamepad. It further comprises a torque output device and a deceleration device. An output shaft of the torque output device is connected with an input end of the deceleration device, an output end of the deceleration device is connected with a rotating shaft of the joystick to apply a torque output by the torque output device to the rotating shaft. When the user operates the joystick to rotate, a certain torque is applied to the rotating shaft after being decelerated by the deceleration device, namely, the corresponding torque is applied to the joystick to form a feedback force to the user.

Abstract: Disclosed is an accidental touch prevention method applied to a wearable device including a touch control structure and a capacitive touch sensor configured to collect capacitance values of at least two touch channels. The distances between the touch channels and the touch control structure are not equal. The method includes: when an event of triggering a touch control structure is detected, obtaining a capacitance value of each touch channel collected by the capacitive touch sensor; determining whether the capacitance values of all of the touch channels meet a preset capacitance value distribution state which is the distribution state of the capacitance values of all of the touch channels when the touch control structure is triggered under the conditions of a non-accidental touch; and if not, determining that the touch control structure has been touched accidentally, and not responding to the event of triggering the touch control structure.
