摘要： An electroacoustic transducer adapted to be mounted on a printed circuit board in which a coil spring is accommodated and supported in a cylindrical recess of a frame while it is fixed to neither a terminal plate nor the frame. Particularly, a protruding pin of the coil spring is passed through a though hole of the terminal plate to allow a leading portion of the protruding pin to be hooked thereon. When the electroacoustic transducer is mounted on the printed circuit board, any horizontal displacement between the compressed spring and the printed circuit board would not cause stress concentration on the coil spring since the coil spring is onlly horizontally shifted in the cylindrical recess until a coil portion of the coil spring hits against the wall of the cylindrical recess.

摘要： The invention provides an electroacoustic transducer capable of preventing degradation in its acoustic performance as a result of the reflow soldering process applied. With the electroacoustic transducer, variation in the minimum resonance frequency Fo of a diaphragm is restrained, stabilizing the acoustic performance by causing a decrease in the minimum resonance frequency Fo of the diaphragm due to irreversible demagnetization of the magnet caused by the reflow soldering temperatures to cancel out an increase in the minimum resonance frequency Fo of the diaphragm due to thermal contraction of a holder member caused by the reflow soldering temperatures.

摘要： The present invention provides an electroacoustic transducer and a method of fabricating the same, employing a lead frame to integrally form a plurality of component parts, thus reducing the number of individual component parts, and improving assembly efficiency. The electroacoustic transducer comprises a base, a yoke fixed to the base, a core, a coil wound around the core, magnet surrounding the coil, a support ring surrounding the magnet, a vibrating plate supported on the support ring, lead terminals fixed to the base, and a case having a sound emitting cylinder and joined to the base so as to cover those components. A gap is formed between the core and the diaphragm. The diaphragm, the gap, the core, the yoke and the magnet form a closed magnetic path. The coil drives the diaphragm for vibration when energized. The yoke and the lead terminals are integrally formed of a common metal material such as the lead frame. The core may be integrally formed with the yoke of the lead frame.

摘要： The present invention provides an electroacoustic transducer which realizes an optimum characteristic thereof utilizing heat caused by reflow soldering without being influenced by the same heat. The electroacoustic transducer includes a magnetic driving portion composed of a base, a core provided upright on the base and a coil wound around the core, wherein a height of the coil at the manufacturing time is set lower by a height which corresponds to thermal expansion of the coil in reflow soldering, and a projection length of the core exposed from the coil at the manufacturing time is set larger by the height which corresponds to thermal expansion of the coil in reflow soldering.
