Method for operating sound converter, involves loading sound converter with direct current voltage with given value and value of direct current voltage is reduced till voltage value reaches neutral value
摘要
<p>The method involves loading the sound converter (SC) with a direct current voltage with a given value. The value of the direct current voltage is reduced till the voltage value reaches a neutral value so that the oscillations of the sound converter are damped or eliminated. The sound converter is formed to transmit an acoustic wave packet of a given frequency in a transmit mode. An independent claim is included for a device for operating a sound converter in a park sensor of a motor vehicle.</p>
