Electro-acoustic converter and electronic device using the same

An electronic device comprising:

• an electro-acoustic converter having;
• a magnetic circuit;
• a frame bonded to the magnetic circuit;
• a diaphragm bonded to a circumferential edge of the frame;
• a voice coil attached to the diaphragm in a manner that a part thereof is located in a magnetic gap of the magnetic circuit;
• a terminal made of a sheet metal having spring property and electrical conductivity, a part of the terminal being fixed to the frame and electrically connected to the voice coil, the terminal having a bent portion and a contact portion for connection to an external circuit;
• and
• a stopper having adjacent portions that protrude from a surface of the frame where the contact portion of the terminal protrudes, a portion of the terminal being disposed between the adjacent portions of the stopper wherein the stopper is configured to restrict bending of the sheet metal constituting the terminal within a threshold value of reversibility of a material of the metal, and
• an electronic circuit connected electrically with the electro-acoustic converter via the contact portion, electronic circuit being configured to supply electric power to the electro-acoustic converter.
