    • It is an object of the present invention to use a simplified structure to improve a strength of a neck portion of a conical diaphragm in the vicinity of a voice coil fixing section, thereby inhibiting an undesired dividing vibration in a speaker device. The speaker device of the present invention comprises: a generally conical diaphragm having an opening formed in a generally central position thereof; a voice coil bobbin fixed in the inner circumferential portion of the foregoing opening of the diaphragm; and a diaphragm reinforcing annular member disposed near a fixing section fixing together the diaphragm and the voice coil bobbin. The annular member includes, in the form of an integrally formed body, a diaphragm reinforcing portion having an inclined surface which contacts an inclined surface of the diaphragm close to the inner circumferential portion thereof and is fixed to the inclined surface of the diaphragm by virtue of an adhesive agent, and a cylindrical portion having a liquid holding portion which is formed between the voice coil bobbin and the annular member and is filled with the adhesive agent.
