摘要： An insert earphone which prevents a sound leakage and improves wearing comfort. An ear chip has a barrel portion and first and second annular flange portions having the shape of a parabola spreading from the top toward the middle and from the middle toward the base of the barrel portion respectively. The first annular flange portion has a smaller outer diameter than the second annular flange portion.

摘要： Disclosed is an electroacoustic transducer which comprises a diaphragm including an elastic plate, an added mass secured to a center portion of the elastic plate. The added mass has a contact portion, which contacts the elastic plate and is shaped to provide a portion to allow for deformation of the elastic plate within an imaginary circle defined by connecting an outer surface portion of the contact portion. Thus, the contact portion can provide a deformable elastic-plate portion within that circle. In other words, it is possible to accomplish such a structure obtained as if by connecting different springs having different spring characteristics, located outside and inside the circle. This structure can suppress and stabilize a variation in resonance frequency (f.sub.0) caused by a change in the amplitude of the diaphragm. The follow-up reproducibility of an output to an input is thus improved enough to cope with the case of using the electroacoustic transducer for AM sounds or attenuating sounds.

摘要： In an electroacoustic transducer, a pair of coil terminals elongating from a voice coil are electrically connected to a pair of terminal members attached to a frame via a flexible printed circuit board, respectively. According to the configuration, even in a case where an electroacoustic transducer is used at a high sound pressure, breakage of the coil terminals hardly occurs. In the flexible printed circuit board, the width of an intermediate portion is set to be smaller than the widths of an end portion on the side of the coil terminals and an end portion on the side of the terminal members. Therefore, the flexibility of the intermediate portion can be enhanced, whereby transmission of characteristic vibration of the flexible printed circuit board to a diaphragm, and stress concentration in the vicinity of the end portions are effectively suppressed.

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.
