Abstract
Official abstract text for this publication.
A speaker includes: an edge having an outer circumference attached on an edge mounting portion of a resin frame by a resin ring provided on a front surface of the outer circumference. Interposed between the edge mounting portion and the resin ring is a projection-like energy director having a part abutting on one of the members and being melted from the part by ultrasonic waves.
First claim
Opening claim text (preview).
The invention claimed is: 1 . A speaker comprising: an edge having an outer circumference attached on an edge mounting portion of a resin frame by a resin ring provided on a front surface of the outer circumference, the edge mounting portion including an energy director having a tip portion abutting on a back surface of the resin ring and being meltable from the tip portion by ultrasonic waves, and an edge compressing rib being more inner than the energy director, the edge compressing rib being configured to press and put pressures on a back surface of the outer circumference of the edge. 2 . The speaker of claim 1 , wherein the edge compressing rib is distanced from the energy director. 3 . A speaker comprising: an edge having an outer circumference attached on an edge mounting portion of a resin frame by a resin ring provided on a front surface of the outer circumference, the resin ring including, on a back surface thereof, an energy director having a tip portion abutting on a front surface of the edge mounting portion and being meltable from the tip portion by ultrasonic waves, and an edge compressing rib being more inner than the energy director, the edge compressing rib being configured to press and put pressure on a front surface of the outer circumference of the edge. 4 . The speaker of claim 3 , wherein the edge compressing rib is distanced from the energy director.
