ABSTRACT:
An improved ceiling mountable acoustic transducer mountable in a ceiling tile without the cutting of a hole. A pair of elongated members which pierce the ceiling tile are attached to a housing which holds the acoustic transducer. The housing is held in contact with the surface of the ceiling tile by a pair of spring clips which engage the elongated members. The electrical connection of the transducer to an acoustical electrical signal source is made through the elongated members to the acoustic transducer by attachment of leads to the clips.
