a stopper disposed at a place corresponding to the first wall and contacting the first wall as to regulate the position of the eyelet terminal in the inserting direction of the eyelet terminal; and
a first protrusion engaged with the second wall,
wherein the second wall is provided at a side wall surface of the hole,
wherein the second wall is constituted by an aperture provided in the connector housing or a cutout provided in the connector housing,
wherein the first wall is provided in the hole,
wherein the eyelet terminal includes a wide section,
wherein the stopper is constituted by a top surface of the wide section in the inserting direction of the eyelet terminal, and
wherein the first wall is positioned behind the second wall along the inserting direction of the eyelet terminal.
2. The loudspeaker frame according to claim 1 ,
wherein the eyelet terminal further includes:
a narrow section extending in one direction from the wide section and protruding outside the connector housing at a rear face of the connector housing, the narrow section having a width smaller than a width of the wide section; and
a terminal section extending in another direction from the wide section and protruding inside the connector housing at a front face of the connector housing.
3. The loudspeaker frame according to claim 1 , wherein a cut surface is formed on the connector housing so as to insert the eyelet terminal easily.
4. The loudspeaker frame according to claim 1 , wherein the eyelet terminal includes a second protrusion for applying a pressure to a part of the connector housing in order to prevent looseness.
5. The loudspeaker frame according to claim 2 , wherein a coupling section is provided at an end of the narrow section, a hole is provided between the coupling section and a root of the narrow section.
6. A loudspeaker comprising:
the loudspeaker frame according to claim 1 ;
a magnetic circuit provided to the loudspeaker frame;
a voice coil located in a magnetic gap of the magnetic circuit; and
a diaphragm fixed to the loudspeaker frame and the voice coil.
7. An electronic device comprising the loudspeaker according to claim 6 .
8. A mobile device comprising the loudspeaker according to claim 6 .
9. The loudspeaker frame according to claim 2 , wherein, in a direction perpendicular to the inserting direction of the eyelet terminal, the narrow section of the eyelet terminal further has the width smaller than the width of the wide section.
10. A loudspeaker frame comprising:
a frame section made of resin;
a connector housing made of resin molded with the frame section;
a hole provided in a bottom of the connector housing; and
an eyelet terminal extending through the hole and having a flat plate shape,
wherein a first wall for regulating a position of the eyelet terminal in an inserting direction of the eyelet terminal and a second wall for regulating the position of the eyelet terminal in a direction opposite to the inserting direction of the eyelet terminal are provided on the bottom of the connector housing,
wherein the eyelet terminal includes:
a stopper disposed at a place corresponding to the first wall and contacting the first wall as to regulate the position of the eyelet terminal in the inserting direction of the eyelet terminal;
a first protrusion engaged with the second wall, and
wherein the second wall is provided at a side wall surface of the hole,
wherein the second wall is constituted by an aperture provided in the connector housing or a cutout provided in the connector housing,
wherein the first wall is provided in the hole,
wherein the eyelet terminal includes:
a wide section;
a narrow section extending in one direction from the wide section and protruding outside the connector housing at a rear face of the connector housing, the narrow section having a width smaller than a width of the wide section; and
a terminal section extending in another direction from the wide section and protruding inside the connector housing at a front face of the connector housing,
wherein the stopper is constituted by a top surface of the wide section in the inserting direction of the eyelet terminal, and
wherein a coupling section is provided at an end of the narrow section, a hole is provided between the coupling section and a root of the narrow section.
11. The loudspeaker frame according to claim 10 , wherein, in a direction perpendicular to the inserting direction of the eyelet terminal, the narrow section of the eyelet terminal further has the width smaller than the width of the wide section.
