Abstract
Official abstract text for this publication.
An acoustic generator includes a vibration body; a first exciter and a second exciter which are disposed on the vibration body; a first damping material disposed on the vibration body and having a first portion which overlaps the first exciter; and a second damping material disposed on the vibration body and having a second portion which overlaps the second exciter. The first damping material is disposed so as to straddle at least a portion of a first segment which is a portion of a contour of the first exciter which portion does not face the second exciter, and the second damping material is disposed so as to straddle at least a portion of a second segment which is a portion of a contour of the second exciter which portion does not face the first exciter.
First claim

1 . An acoustic generator, comprising: a vibration body having two surfaces positioned with a gap therebetween in a first direction; a first exciter and a second exciter which are disposed on the vibration body; a first damping material having a first portion which overlaps the first exciter when viewed in the first direction, the first damping material being disposed on the vibration body; and a second damping material having a second portion which overlaps the second exciter when viewed in the first direction, the second damping material being disposed on the vibration body, when a portion of a contour of the first exciter which portion does not face the second exciter is described as a first segment and a portion of a contour of the second exciter which portion does not face the first exciter is described as a second segment, when viewed in the first direction, the first damping material being disposed so as to straddle at least a portion of the first segment, and the second damping material being disposed so as to straddle at least a portion of the second segment when viewed in the first direction. 2 . The acoustic generator according to claim 1 , wherein the first exciter has a third portion which does not overlap the first damping material when viewed in the first direction, and the second exciter has a fourth portion which does not overlap the second damping material when viewed in the first direction. 3 . The acoustic generator according to claim 2 , wherein when a portion of the contour of the first exciter which portion faces the second exciter is described as a third segment and a portion of the contour of the second exciter which portion faces the first exciter is described as a fourth segment, when viewed in the first direction, the third portion is in contact with at least a portion of the third segment, and the fourth portion is in contact with at least a portion of the fourth segment when viewed in the first direction. 4 . The acoustic generator according to claim 2 , wherein an area of the third portion and an area of the fourth portion are different from each other. 5 . The acoustic generator according to claim 2 , wherein a shape of the third portion and a shape of the fourth portion are different from each other. 6 . The acoustic generator according to claim 1 , wherein an area of the first portion and an area of the second portion are different from each other. 7 . The acoustic generator according to claim 1 , wherein a shape of the first portion and a shape of the second portion are different from each other. 8 . The acoustic generator according to claim 1 , wherein the first damping material and the second damping material are integrated. 9 . The acoustic generator according to claim 1 , further comprising: a resin layer which covers at least a portion of the vibration body, wherein the first damping material and the second damping material are attached to the vibration body via the resin layer. 10 . An acoustic generation device, comprising: the acoustic generator according to claim 1 ; and an enclosure attached to the acoustic generator. 11 . An electronic apparatus, comprising: the acoustic generator according to claim 1 ; and an electronic circuit connected to the acoustic generator.
