摘要： A microphone chip and a microphone. The microphone chip includes: a base including an inner cavity; a diaphragm including a diaphragm inner part and a diaphragm outer part that are connected to the diaphragm inner part, the diaphragm being supported on the base by means of the diaphragm outer part, and the diaphragm inner part being arranged to be opposite to the inner cavity; and a limiting member supported on the base and located at two opposite sides of the diaphragm along a vibration direction of the diaphragm, the limiting member being spaced apart from the diaphragm, and the limiting member being configured to limit an amplitude of the diaphragm inner part. When the diaphragm inner part moves to a certain displacement, the limiting member can limit further movement of the diaphragm inner part, thereby reducing a damage risk caused by excessive displacement of the diaphragm under high sound pressure.

摘要： A method for compensating a signal of a motor includes acquiring an original signal and nonlinear parameters of the motor; calculating a compensation signal for the original signal according to the acquired nonlinear parameters; and loading the calculated compensation signal into the motor to excite the motor to vibrate. An electronic apparatus and a storage medium are also provided. In this method, the original excitation signal is compensated for nonlinearity according to the nonlinear motor parameters, and is then used for exciting the motor. Therefore, the actual vibration effect can be closer to the expected effect as designed, which can bring more desirable tactility experience.

摘要： A knob device for vehicle includes a knob unit and a locking unit. The knob unit includes a rotating cover, a rotary shaft and a motor configured to drive the rotating cover to vibrate. The locking unit includes a rotary wheel which includes a main body fixed to the rotary shaft and locking notches formed at a periphery of the main body. The locking notches are sunk from the periphery of the main body toward a center of the main body in radial directions of the main body. The locking unit further includes a locking pole configured to be inserted into one of the locking notches to block rotation of the rotary wheel, and an actuator configured to drive the locking pole to move. The knob device applies a locking unit which is capable of locking the rotary wheel, thereby realizing diverse use requirements.

摘要： The present application discloses a screen sounding system having a screen, an exciter for driving the screen, and a magnetic element fixedly connected with the screen. The exciter includes a housing with an accommodation space and a magnet arranged in the accommodation space. The housing is fixed on the magnetic element through magnetic attraction force between the magnet and the magnetic element. Compared with the related art, the screen sounding system disclosed by the present application facilitates removal and installation of the exciter. The position of the exciter can be adjusted through slip. Meanwhile, the magnetic element can avoid an influence on the screen caused by a magnetic field of the exciter.
