PROBLEM TO BE SOLVED: To improve a strength and durability of a fitting part with a voice coil in a vibrator where a pair of vertically split cylindrical surfaces is disposed in parallel like a Ryffel type speaker, and to further improve a transmission property of vibrations between the voice coil and the vibrator.SOLUTION: An electroacoustic transducer includes: a vibrator 1 in which a pair of vertically split cylindrical surfaces 15 is formed in parallel and a valley part 16 is formed between side parts of one of the neighboring vertically split cylindrical surfaces 15; a conversion part 2 including a voice coil 20 and a magnet mechanism 21 for converting vibrations in a depth direction of the valley part 16 of the vibrator 1 into an electric signal corresponding to the vibrations; and a support part 35 which supports the vibrator 1 in such a manner that the vibrator can be vibrated in the depth direction of the valley part 16. In the middle of extending the valley part 16 of the vibrator 1, a cylindrical part 13 that connects the vibrator and the voice coil 20 is provided in the depth direction of the valley part 16.SELECTED DRAWING: Figure 3 |
