Abstract
A speaker includes: a vibrating body including a diaphragm and an edge; a coil directly or indirectly attached to the diaphragm; a pair of lead wires electrically connected to the coil; a yoke; a frame which supports the diaphragm via the edge and in which a magnetic circuit is housed; and an inner terminal to which the lead wire is connected. A passage through which the lead wire passes is disposed between the coil and the inner terminal.
Claims5
A speaker comprising:
- a vibrating body including a diaphragm and an edge;
- a coil directly or indirectly attached to the diaphragm;
- a pair of lead wires electrically connected to the coil;
- a yoke including a first side portion and a second side portion disposed such that one end of the first side portion is adjacent to one end of the second side portion;
- a frame which supports the diaphragm via the edge and in which a magnetic circuit is housed;
- and
- an inner terminal to which the lead wire is connected, wherein
- one of the pair of lead wires, pulled out from the coil through a passage between the adjacent ends of the first side portion and the second side portion, extends toward an opposite side of an acoustic wave emitting side of the coil,
- the coil has a rectangular shape having a straight portion and a curved portion,
- the one of the pair of lead wires, pulled out of the coil, is pulled out of the straight portion to reduce a stress applied to a pull-out portion of the one of the pair of lead wires,
- the one of the pair of lead wires, having bent portions, has a bearing power and supports the coil to suppress a generation of abnormal vibration and to maintain a balance of the coil.
