Abstract

A light bulb loudspeaker and sound system where a wireless or wire receiver, amplifier and power supply can be mounted inside of the boundary defined by a light bulb and base where the glass bulb can be used as a sound radiating diaphragm, or alternatively, the bulb can be made to move as a plunger and this act as a sound diaphragm. A transducer can convert audio from the amplifier into sound and thereby excite the glass bulb or cause it to move. A baffle can optionally be provided in the form of a lamp shade or otherwise. Different channels can provide different audio signals to different light bulb loudspeakers in the same physical area, or an electrical signal could be multiplexed. A small base station unit can transmit radio or wire signals containing audio information from an audio source such as a stereo. The filament can optionally be used as a radio receiving antenna.
