Abstract:
The present invention provides a vibration audio system for transmitting an audio signal outputted from a sound source to a listener in the form of vibration while reducing output level of the signal and power consumption. The system includes an envelope detection unit (204) for detecting an envelope signal of the audio signal outputted from a sound source, a vibration transmission member for allowing the listener to perceive vibration of a low-frequency sound outputted from a low-frequency output speaker that outputs audio signals, and a frequency conversion unit (205) for generating an audio signal frequency-converted on the basis of resonant frequencies by multiplying the envelope signal by sine waves having the same frequencies as resonance frequencies obtained from an impulse response of the low-frequency output speaker disposed in the vibration transmission member. The audio signal frequency-converted by the frequency conversion unit (205) is outputted from the low-frequency output speaker.

Abstract:
The present invention pertains to a method of capacitive stimulation of an oscillator control in sensors used for capacitive measurement of strengh, acceleration and especially rotation speed based on the Coriolis principle. In this method, the control is stimulated using high frequency pulse packs, free of continuous voltage and constant in amplitude, of which the width or phase angle relative to the stabilized oscillation speed is adjusted for the purpose of resetting to the initial state or correcting tolerances. Another embodiment of the inventive method allows, in case of electrode oscillators installed in pairs and symmetrically relative to the rotation axis, for high frequency voltages to be obtained that are identical and constant in amplitude. The frequency chosen for these voltages is clearly above the oscillator frequency, resulting in a certain attractive force acting upon the oscillator by shifting the mutual phase lag in the control voltages. In the case of rotation speed sensors the setting of which is based on the closed-loop principle, a resetting to the initial state may also be ensured. The invention also enables problems related to coupling the stimulating signal in the selector channel of a micromechanical oscillator system to be overcome.
