Abstract
An acoustic sensor including an electroacoustic transducer and an electrical conductor. The electroacoustic transducer includes a plate-shaped transducer element, which is configured to output an acoustic signal when it is excited by the electrical signal. The electroacoustic transducer furthermore includes a first contacting, which is situated on at least one of the surfaces of the plate-shaped transducer element in such a way that it has at least one portion which ends flush with the outer circumference of the first or second surface of the plate-shaped transducer element, or extends at least partially outside the outer circumference of the first or second surface of the plate-shaped transducer element. The electrical conductor includes a contact area in contact with an outer circumference of the first contacting, the contact area of the electrical conductor being situated in a plane defined by the first surface, outside an area which overlaps with the electroacoustic transducer.
