Abstract: A vibration generation device includes: a base configured to transmit vibration to an object; a pendulum supported by the base swingably around a rotation axis; and a driving unit including a magnet, and a coil disposed to face the magnet in a non-contact manner, and configured to swing the pendulum. One member of the magnet and the coil is provided at a position on the pendulum away from the rotation axis. The base includes a support portion supporting the pendulum swingably around the rotation axis. A part of an extension surface of a facing surface of the support portion facing the pendulum is included in a swingable range of the pendulum. The support portion is provided outside the swingable range of the pendulum when viewed along the rotation axis.

Abstract: An ultrasonic sensor includes a signal generation circuit, an amplifier, and a matching circuit as a transmission-side circuit. The signal generation circuit includes a driving signal generation circuit that generates a driving signal for transmitting ultrasonic waves from an ultrasonic transducer for transmission and reception and a reverberation suppression signal generation circuit that generates a reverberation suppression signal for suppressing reverberation occurring at the ultrasonic transducer from which the ultrasonic waves are transmitted. The reverberation suppression signal generation circuit generates the reverberation suppression signal having a frequency of 1/2 times the frequency of the driving signal and applies the reverberation suppression signal to the ultrasonic transducer at a time delayed from the driving signal by a half wavelength. With the above configuration, an ultrasonic sensor driving circuit capable of reducing the duration of the reverberation occurring at the ultrasonic transducer is provided.

Abstract: A mechanical resonator has an electronically adjustable resonance frequency and is especially adapted to be used as a tunable vibration absorber. The mechanical resonator includes an inertial mass mounted on a free end of a spring, which is secured at its other end to the structure that is to be vibrationally damped. In order to vary the resonant frequency of the resonator, an electromechanical converter such as a piezoelectric element is connected to the spring and/or the inertial mass, and a displacement and/or acceleration sensor provides a sensor signal that is dependent on the respective displacement and/or acceleration of the spring and/or the inertial mass. An electronic control circuit generates an actuating signal based on the sensor signal. The actuating signal is applied to the electro-mechanical converter, which responsively exerts an adjusting force onto the spring and/or the inertial mass. The control circuit may include one or more variable amplifiers, inverters, and phase shifters, to control the actuating signal such that the adjusting force exerted by the electromechanical converter either counteracts or reinforces the bending force exerted by the inertial mass on the spring. In this manner, the effective total spring constant of the resonator can be increased or decreased relative to the inherent spring constant of the spring, whereby the resonant frequency is adjusted.
