Claims

[Claims for Utility Model Registration] An outer container in which a power supply terminal is formed, an inner container combined with the outer container, an electric circuit for driving etc. housed in the inner container, and the outer container. In an acoustic transducer comprising a substrate on which an electrode for contact connection of a power supply terminal of a container is formed, protrusions are formed on the inner and outer walls of the inner container so that the shapes of the inner and outer walls are asymmetrical, and , a recess that fits into the protrusion is provided in a portion of the substrate and the outer container corresponding to the protrusion, and when the outer container, the inner container, and the substrate are assembled, these three are assembled in a predetermined positional relationship,
A case for an electromagnetic acoustic transducer, characterized in that a terminal formed on an outer container and an electrode formed on a substrate are connected in a predetermined relationship.
