Abstract
Abstract A crystal oscillator including a crystal element designed to oscillate at a given frequency when subjected to an exciting voltage, and mounted parallel to and on a base through at least a wad made of at least a thin wound wire. Advantageously, the wire is randomly wound and is electrically conductive. The wad is elongated and is disposed parallel to said crystal and to said base.
