Abstract: A vibration apparatus and a local vibration adjustment method therefor, and an electronic device are provided. The vibration apparatus includes: two or more excitation modules, a vibration sensing module and a processing module. The vibration sensing module may obtain a vibration sensing signal in a non-target vibration region while target haptic sensation is generated in a target vibration region. The processing module drives, based on the vibration sensing signal, an excitation module in the non-target vibration region to generate corresponding damping vibration to counteract the non-target vibration, thereby weakening the vibration in the non-target vibration region.

Abstract: An ultrasonic apparatus includes an ultrasonic transducer, a transmitting circuit, a receiving circuit, a Q-factor measuring circuit, and a frequency measuring circuit. The ultrasonic transducer is a three-terminal ultrasonic transducer that includes a transmitting electrode, a receiving electrode, and a common electrode. The transmitting circuit outputs a driving signal to the transmitting electrode to cause the ultrasonic transducer to transmit ultrasonic waves. The receiving circuit receives a receive signal from the receiving electrode. The frequency measuring circuit measures a resonant frequency of the ultrasonic transducer from a reverberation signal in the receive signal. The Q-factor measuring circuit measures a Q factor of the ultrasonic transducer from the reverberation signal in the receive signal.

Abstract: A filtering device includes a filtering circuit that connects a voltage source to a sensor and a switching circuit connected in parallel with the filtering circuit that allows current from the voltage source to bypass the filtering circuit and flow through the switching circuit. The switching circuit receives a mode signal from the sensor that indicates whether the sensor is in a high current or a low current mode, the switching circuit closes when the sensor is in the high current mode, and the switching circuit is opens when the sensor is in the low current mode.

Abstract: The invention relates to an ultrasonic measuring system (10), in particular for measuring distance and/or as a parking aid in vehicles, having an electroacoustic ultrasonic transducer (12) which has a oscillating element (14), does not have a voltage converter, can be alternately operated as an ultrasonic transmitter and an ultrasonic receiver and has a signal connection (16), which is used either as an input or as an output of the ultrasonic transducer (12), and an earth connection (18) which is connected to earth, and a control and evaluation unit (20) for exciting the oscillating element (14) of the ultrasonic transducer (12) to emit ultrasonic waves for operating the ultrasonic transducer (12) during a transmission interval for the purpose of subsequently deactivating the excitation of the oscillating element (14) and attenuating the latter during a decay phase and for receiving and processing ultrasonic waves in a reception interval. The control and evaluation unit (20) has a bridge circuit (28) which is connected to a DC supply voltage (80) and has controllable switches (30 to 40) and a charge storage capacitance (42), the polarity of which can be reversed and which is intended to alternately output a positive and a negative excitation voltage for the signal connection (16) of the ultrasonic transducer (12) during the transmission interval. The control and evaluation unit (20) outputs a voltage pulse of substantially 0 V at the end of the transmission interval for the signal connection (16) of the ultrasonic transducer (12).
