<p>PROBLEM TO BE SOLVED: To provide a capacitor headphone unit which suppresses vibration of a fixed electrode and brakes resonance even if the resonance occurs at a fixed electrode side.SOLUTION: A capacitor headphone unit includes: fixed electrode plates 5 and 6; a diaphragm which is disposed oppositely to the fixed electrode plates; and frame-shaped insulation seats 7 and 8 supporting edges of the fixed electrode plates. The insulation seat is abutted to the edge at one surface side of the fixed electrode plate at least and adhered to the fixed electrode plate by an adhesive 20 having viscosity in the abutted part. The one surface side of each of the fixed electrode plates to which the insulation seats are abutted is coated with the adhesive in a circumferential direction so as to cover edge portions 10, 11, 12 and 13 of the abutted part.</p> |
