PROBLEM TO BE SOLVED: To provide a speaker for a hearing-impaired person with high original sound reproduction capability while sound pressure is amplified.SOLUTION: In a speaker 10, an end on a side opposite to a side where a coil 48 in a bobbin 24 is wound expands toward an outer side of a radial direction of the bobbin 24. A flange part 52 being an expanding part is bonded to a vibration section 21 with adhesive bond BND. Thus, sufficient bond strength can be secured when the adhesive bond BND is thinly applied only to a part sandwiched between the flange part 52 and a contact part in the vibration section 21. |
