Abstract

PURPOSE:To realize the decline and the improvement of input of a lowest resonance frequency f0 being a performance request for voice reproduction concerning a speaker used for a multi-media equipment, etc. CONSTITUTION:The outer peripheral part of a vibration plate 16 is made to be larger than the roll inner diameter (a) of an edge material 17 and the outside dimension (c) of a damper 18 is made larger than the role outer diameter (b) of the edge material 17. Thus, the weight of the vibration plate 16 is balanced with the roll inner diameter (a) of the edge 17 as a fulcrum so that the rolling is prevented and the input is improved. Moreover, the outside dimension of the damper 18 is made larger than the conventional one so that the lowerest resonance frequency f0 is reduced.

As described above, the speaker according to the present invention is
When the outer peripheral portion of the diaphragm is formed to have an outer size larger than the inner diameter of the roll of the edge material, and the mass of the entire diaphragm is A, the mass of the diaphragm outside the inner diameter of the roll of the edge material is 0.4 A to 0. The size of the damper is larger than that of the conventional speaker by adopting a structure in which the damper having a larger outer diameter than the roll outer diameter of the edge material is attached to the peripheral portion of the yoke forming the magnetic circuit. Since the minimum resonance frequency f 0 can be reduced and the weight of the diaphragm can be balanced with the inner diameter of the roll of the edge material as a fulcrum, the rolling phenomenon of the diaphragm can be eliminated and the input can be improved. A speaker that is designed can be realized. In addition, as an additional effect, in the middle-high range in the frequency characteristics, the mass of the diaphragm portion outside the roll inner diameter of the edge material can be ignored in operation, the sound pressure can be improved, and the sound quality is also excellent. A speaker can be realized.
