Abstract
A loudspeaker includes: a connection wire that connects a voice coil and a connection terminal, wherein the connection terminal includes: a base; and a first protrusion and a second protrusion that integrally protrude from the base, and a deformed portion is included in at least one of a boundary portion between the base and the first protrusion or a boundary portion between the base and the second protrusion, the deformed portion being a portion that is plastically deformed in a direction in which the first protrusion and the second protrusion approach each other.
Claims11
A loudspeaker comprising:
- a magnetic circuit having a magnetic gap;
- a voice coil disposed inserted in the magnetic gap;
- a cone to which the voice coil is attached;
- a frame that holds the magnetic circuit and the cone;
- a connection terminal attached to the frame;
- and
- a connection wire that connects the voice coil and the connection terminal, wherein
- the connection terminal includes:
- a base;
- a first protrusion that integrally protrudes from the base;
- and
- a second protrusion that integrally protrudes from the base and is separated from the first protrusion by a gap, and
- a deformed portion is included in at least one of a boundary portion between the base and the first protrusion or a boundary portion between the base and the second protrusion, the deformed portion being a portion that is plastically deformed in a direction in which the first protrusion and the second protrusion approach each other.
A method for manufacturing a loudspeaker that includes a magnetic circuit having a magnetic gap, a voice coil disposed inserted in the magnetic gap, a cone to which the voice coil is attached, a frame that holds the magnetic circuit and the cone, a connection terminal attached to the frame, and a connection wire that connects the voice coil and the connection terminal, the connection terminal including a base, a first protrusion that integrally protrudes from the base, and a second protrusion that integrally protrudes from the base and is separated from the first protrusion by a gap, the method comprising:
- inserting the connection wire in the gap between the first protrusion and the second protrusion, the connection wire being disposed to intersect with an arrangement direction of the first protrusion and the second protrusion;
- and
- pressure bonding the connection wire by crimping the connection terminal to cause a projecting end portion of the first protrusion and a projecting end portion of the second protrusion to approach each other.
