Abstract
The electro-acoustic transducer (1) includes a multitude of piezoelements (2) which are arranged in a holder (3) in recesses (5), in which the piezoelement (2) is positively held in the circumferential direction. Furthermore, a holding structure is provided which positively engage over the piezoelements (2) at their end faces (9) and thus hold these. This formation is then embedded into a curing plastic casting compound (4) after wiring.
Claims16
An electro-acoustic transducer comprising:
- one or more holders;
- and
- a multitude of piezoelements which are arranged in the one or more holders, wherein recesses or holding elements are provided in one of the one or more holders or several holders and each circumferentially surround one of the piezoelements with a positive fit at least in sections, wherein the one or several holders comprise holding means which positively hold the one of the piezoelements on end faces thereof.
An electro-acoustic transducer, comprising:
- a plurality of piezoelements;
- and
- a holder, wherein at least the plurality of piezoelements are arranged in the holder, the holder comprising one of recesses and holding elements, each of the one of recesses and holding elements being configured to circumferentially surround one of the piezoelements with a positive fit at least in sections, the holder further comprising a holding means holding one end face of the one of the piezoelements via a positive fit connection.
