PROBLEM TO BE SOLVED: To provide a smooth frequency characteristic in a wide bandwidth.SOLUTION: The electroacoustic transducer 10 includes: a diaphragm 13 which vibrates by being driven by drive sections 11, 12 of a driver unit 10, and outputs a voice; a baffle 11 which retains the diaphragm 13; an opening section 25 which penetrates through front and rear faces of a baffle 21; and an acoustic resistance material 22 which is provided at a position of the opening section 25 on a surface of the baffle 21. The electroacoustic transducer 10 has a plurality of passages for passing the voice generated from the diaphragm 13 in a rear face direction of the baffle 21.SELECTED DRAWING: Figure 4 |
