Abstract
An electroacoustic transducer having a housing with at least two parts, e.g., a cover and a bottom portion, and a diaphragm situated therein. Specifically and illustratively, an edge portion of the diaphragm is attached to one of two opposing edges of side walls of the cover and the bottom portion and, once the housing is assembled, is located between these edges. The edge to which the diaphragm is attached extends in a first plane defined by a central portion of the diaphragm or in a second plane parallel thereto.
Claims6
An electroacoustic transducer comprising:
- a housing having first and second housing parts;
- a diaphragm, received within the housing, comprising a central diaphragm portion and an edge portion extending around the central diaphragm portion;
- and
- means for converting either an electric signal into vibration of the central diaphragm portion or vibration of the central diaphragm portion into an electric signal;
- wherein:
- the edge portion of the diaphragm is made from at least a part of material that forms the central diaphragm portion, extends in a first plane defined by the central diaphragm portion or in a second plane parallel to the first plane and is attached to an edge portion of a side wall of the first housing part;
- and
- the edge portion of the diaphragm is located between two opposing edge portions of the first and second housing parts.
