The bar-like resonator has an initial section having one end region thereof connected to the connection surface of the shell construction and an opposite end region. A substantially straight and elogate intermediate section extends from the opposite end region of the initial section to an end and a turning-point section extends from the end of the intermediate section to an end. A substantially straight and elongate end section has one end connected to the end of the turning-point section so as to extend adjacent to the intermediate section and supporting means connect to the connection surface of the shell construction for supporting the bar-like reasonator at least at one of the end section and turning-point.
