    摘要: In the manufacturing process of an electroacoustic transducer with a vibration function, the mechanical resonance frequency of a vibration part (13) is measured so as to determine the weight of a resonance frequency adjustment weight (14) to be added and the position where the vibration part (13) is attached to a frame (16) according to the difference between the mechanical resonance frequency of the vibration part (13) and the desired mechanical resonance frequency. Depending on the determination, the weight (14) is attached to the vibration part (13), or a suspension (12) is again coupled to the frame (16) after the first fixing. Thus, a predetermined mechanical resonance frequency f0 is stably obtained. As a result, an electroacoustic transducer with a vibration function having a stable mechanical resonance frequency of the vibration part (13) can be manufactured.
