An electroacoustic transducer and a wireless electroacoustic transducer are provided to improve sound quality by applying different filtering schemes to different music contents. An electroacoustic transducer includes an earphone, a music code, and a music filter-remote controller(150). The earphone includes a driver unit for converting an electrical signal to a vibration of a diaphragm. The music code electrically couples the earphone with a portable multimedia device. The music filter-remote controller is arranged in the middle of the music code and includes a mode switch button, which selects an input signal in one of a voice signal mode and an audio signal mode. The music filter-remote controller applies different filtering schemes to voice and music signals. The music filter-remote controller includes an input portion(151), a music divider(152), a voice filter portion(153), an audio filter portion(154), and an output portion(155). |
