Electroacoustic transducer and attachment structure thereof |
摘要 |
An electroacoustic transducer 1 has: a base 24 made of magnetic material; a magnetic core 22 provided erectly on the base 24; a diaphragm 20 supported so as to separate from a forward end of the magnetic core with an air gap therebetween; a magnet 25 constituting a magnetic circuit together with the base 24, the magnetic core 22 and the diaphragm 20 so as to apply a magnetostatic field to the magnetic circuit; a coil 23 for applying an oscillating magnetic field to the magnetic circuit; and a support ring 26 for supporting the diaphragm 20; wherein all the members constituting the electroacoustic transducer are enclosed in the base 24 and a casing 10; tapered coil spring terminals 40 are fixed to a wiring board 30 attached to the bottom surface of the base 24; and a skirt portion 13 of the casing 10 abuts against a circuit board 51 in the condition that the electroacoustic transducer 1 is mounted on the circuit board 51, so that the spring terminals 40 are prevented from being compressed beyond necessity.
