    Abstract: The present invention is directed to a high-powered (e.g., > 500 W) ultrasonic generator for use especially for delivering high-power ultrasonic energy to a varying load including compressible fluids. The generator includes a variable frequency triangular waveform generator coupled with pulse width modulators. The output from the pulse width modulator is coupled with the gates of an Isolated Gate Bipolar Transistor (IGBT), which amplifies the signal and delivers it to a coil that is used to drive a magnetostrictive transducer. In one embodiment, high voltage of 0-600VDC is delivered across the collector and emitter of the IGBT after the signal is delivered. The output of the IGBT is a square waveform with a voltage of +/- 600V. This voltage is sent to a coil wound around the ultrasonic transducer. The voltage creates a magnetic field on the transducer and the magnetorestrictive properties of the transducer cause the transducer to vibrate as a result of the magnetic field. The use of the IGBT as the amplifying device obviates the need for a Silicon Controlled Rectifier (SCR) circuit, which is typically used in low powered ultrasonic transducers, and which would get overheated and fail in such a high-powered and load-varying application.

    Abstract: A mobile terminal with an electromagnetic actuator for generating speech, buzzing sound, or low-frequency vibration. The mobile terminal generates little abnormal sound. In this electromagnetic actuator, the terminal lugs are short-circuited, the terminal lugs are electrically connected to amplifiers, or an amplifier is electrically connected to a signal generator for generating a constant-voltage signal or a constant-frequency signal. In such a way, the abnormal sound caused by the vibration of a mechanical vibration system of the actuator is reduced.

The vibrator (6) comprises a stationary electromagnet (8) and an oscillatorily suspended armature (10) as well as a vibration regulation circuit for adjusting the oscillation amplitude of the armature (10). The vibrator regulation circuit (13) is adapted to successively regulate this amplitude upwards.
