摘要： This approaching vehicle notification sound speaker device is equipped with a voice coil for conducting an electrical signal, a cylindrical voice coil bobbin on which the voice coil is wound, an insulating sheet, and a cap. The sheet is wound on the voice coil bobbin at a position closer to the sound-emitting side than the voice coil, the cap is disposed closer to the sound-emitting side than the voice coil bobbin, the voice coil bobbin and the cap are made of an aluminum-containing material, and the sheet is formed with the inclusion of an aramid-based nonwoven fabric.

摘要： Provided is a speaker device in which reproduction sound pressure is increased, and heat resistance and water resistance are improved. The speaker device includes: a diaphragm formed of a film containing polyimide; and a frame for supporting the diaphragm. A cross-section passing the center of the diaphragm and parallel to a sound emission direction includes sequentially from an inner periphery to an outer periphery of the diaphragm along the sound emission direction: a first bent plate portion having a concave arc; a second bent plate portion having a convex arc; a third bent plate portion having a concave arc; and a fourth bent plate portion having a convex arc. An area of the first bent plate portion is larger than any of areas of the second, the third, the fourth bent plate portions.

摘要： A housing structure for a sound generator includes a base portion having a separation wall; a case portion that defines a first space with the base portion; a covering portion that defines a second space with the base portion; a frame portion that projects toward the second space from the separation wall; a screen wall disposed on an outer side of the frame portion to define a groove between the screen wall and the frame portion; and a screen board arranged on an inner side of the screen wall. The screen board is distanced from the frame portion and the screen wall.

摘要： A sound production device for a vehicle includes: a speaker that causes a diaphragm to vibrate thereby producing sound; and a housing receiving the speaker and having a sound passage through which the sound produced by the speaker passes and a sound emission hole that causes the sound passed through the sound passage to externally emit. Plural resonant chambers having different resonant frequencies are defined in the sound passage, such that the sound passage has a labyrinth structure that is able to prevent a foreign substance form entering the diaphragm from the sound emission hole.

摘要： A base portion has a separation wall, and an air hole is defined in the separation wall. A case portion defines a first space with the separation wall of the base portion. A covering portion defines a second space with the separation wall of the base portion. A waterproof and breathable sheet covers the air hole. A water guiding portion is arranged adjacent to a surface of the sheet not to contact the surface of the sheet. The water guiding portion is located between the covering portion and the sheet.
