Acoustic pressure pulse generator |
摘要 |
An apparatus for generating acoustic pressure pulses in an acoustic medium has a membrane that can be driven which adjoins the acoustic medium and which is driven in an impact-producing manner. The membrane is mechanically pre-stressed so that it returns into its initial position after a pressure pulse is generated.
