Abstract

PURPOSE:To achieve the reduction of high frequency distortions and chattering sounds without degrading sound pressure frequency characteristics and directivity by bonding the outside circumference of a plurality of cone form vibrating parts with bonding parts of small stiffness. CONSTITUTION:A diaphragm 23 consists of a plurality of vibrating parts 21 and bonding parts 22. The vibrating parts 21 are formed in cone form of various foam molding materials like, e.g., pulp, etc. The bonding parts 22, which are for mutually bonding the outside circumferences of the vibrating parts 21, are formed of rubber base high polymer materials or the like of stiffness smaller than that of the vibrating parts 21. Integrating the respective vibrating parts 21 by means of the bonding parts 22 in this way constitutes equivalently one diaphragm 23 and this diaphragm 23 is supported and fixed at its circumferential edge part by a frame 24. On the other hand, driving devices 25 driving the diaphragm are provided in a plurality respectively corresponding to the vibrating parts 21. Thereby, higher harmonic distortions and chattering sounds may be reduced.
