PURPOSE:To eliminate a bonding section of dust preventing damper of a sup porter and obtain a compound type speaker low in whole height by bonding an internal circumferential edge section of a dust preventing damper to a tweet er. CONSTITUTION:A tweeter 7 is supported on a supporter 10 on a bottom plate 9 of a woofer 8. An outer circumferential edge section of a dust preventing damper 11 for carrying out a dust preventing in a gap of the woofer 8 is bonded to a cone 12 of the woofer 8. An internal circumferential edge section of the dust preventing damper 11 is bonded to a bonding step section 13a provided on an outer circumferential section of a lower end section of a bottom plate 13 of the tweeter 7. Thereby, the inner circumferential edge section of the dust preventing damper 11 is bonded to a bonding step section 13a of the bottom plate 13 of the tweeter 7 and the bonding section of the dust preventing damper of the supporter 10 is eliminated and thereby a compound type speaker low in all the height can be formed. During a large amplitude, the dust preventing damper 11 is no collided against the tweeter 7. |
