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（中）：
本发明提供了一种电声换能器，该电声换能器能够防止由于应用回流焊接过程而导致其声学性能下降。 通过电声换能器，膜片的最小共振频率Fo的变化受到抑制，通过引起由回流焊接温度引起的磁体的不可逆退磁而导致的膜片的最小共振频率Fo的降低来抵消声学性能的稳定 由于由回流焊接温度引起的保持器构件的热收缩导致振动膜的最小共振频率Fo增加。
