Door trim speaker grille with electroluminescent lamp and injection molding method of making same
View Patent ↗A door trim speaker grille with an electroluminescent lamp for use with an audio speaker of a vehicle. The electroluminescent lamp is positioned for emitting visible light through sound passages in the speaker grille. In certain embodiments of the invention, the electroluminescent lamp may be integrally molded with the speaker grille. One method of forming the door trim speaker grille is by an injection molding process that places the electroluminescent lamp as an insert in the mold cavity.
1. An automotive interior component for use with an audio speaker of a vehicle, comprising:
a door trim panel;
a speaker grille mounted to said door trim panel, said speaker grille with a plurality of sound passages for transmitting sound emitted by the audio speaker; and
an electroluminescent lamp positioned between the audio speaker and said speaker grille, said electroluminescent lamp oriented for emitting visible light, when powered, through said sound passages, wherein said speaker grille and said electroluminescent lamp comprise a unitary molded assembly.
2. The automotive interior component of claim 1 wherein said electroluminescent lamp includes a plurality of apertures registered with said sound passages, said apertures for transmitting sound emitted by the audio speaker.
3. The automotive interior component of claim 2 wherein said apertures are smaller in diameter than said sound passages and circumscribed by said sound passages.
4. The automotive interior component of claim 1 wherein said speaker grille is an integrally molded portion of said trim panel.
5. The automotive interior component of claim 1 further comprising:
an audio signal source coupled with the audio speaker; and
a controller connected between said audio signal source and said electroluminescent lamp, said controller capable of converting output signals from said audio signal source into changes in light intensity of the visible light emitted from said electroluminescent lamp.
