    Abstract: A vibration generating device that can make a relatively heavy vibration member produce sufficient vibration. A vibration generating device has: a vibration member; multiple actuators that are connected to the vibration member; and a stationary element that supports the vibration member via the multiple actuators. Each of the multiple actuators comprises: a supporting body to which the vibration member is fixed; a movable element; a first elastic member that is connected to the supporting body and the movable element; and a magnetic drive circuit (a first magnetic drive circuit and a second magnetic drive circuit) that makes the movable element move linearly back and forth relative to the supporting body. The multiple actuators are supported by the stationary element via a second elastic member. The first elastic member and the second elastic member comprise a gelatinous silicone gel or the like.

    Abstract: A sound wave generator includes a speaker control circuit and a speaker. The speaker control circuit includes a signal generating unit that is configured to generate an electric signal having a humming frequency property. The humming frequency property includes a plurality of frequencies that have an overtone relationship with respect to A Hz and are pitched at the A Hz, the A Hz being a target generation frequency and corresponding to a low pitch frequency in an audible range. The speaker generates a sound wave from the electric signal by applying the electric signal to a vibration plate that produces the sound wave.

    Abstract: In a notifying device comprising a notifying unit 2 having incorporated therein a vibrator to be resonated by a drive signal fed thereto, and a signal preparing circuit 5 for feeding the drive signal to the notifying unit 2, the signal preparing circuit 5 prepares a drive signal Dv varying in frequency within a predetermined range including the resonance frequency of the vibrator of the unit 2 and feeds the signal to the notifying unit 2. The variation of frequency of the drive signal is determined in correspond relation with a variation in the resonance frequency of the vibrator due to tolerances for specifications which govern the resonance frequency. The drive signal has an alternating waveform of rectangular waves or sine waves, and the frequency thereof varies periodically from 1.37 to 2.98 Hz. The notifying device achieves a satisfactory notifying effect despite the variation of the resonance frequency of the vibrator.
