  • Publication number: 20140153769
    Abstract: An electronic device includes a first housing, a second housing engaged with the first housing, a circuit board enclosed between the first and second housings, two speakers, and an antenna. The speakers and the antenna are attached to two sides of the circuit board. The first housing defines two receiving recesses in a surface facing the circuit board and two first through holes each adjacent to one corresponding receiving recess. Each receiving recess defines a second through hole in a bottom. The speakers are received in the receiving recesses. The receiving recesses communicate with the vents to form front resonating chambers for the speakers. The circuit board defines two third through holes aligned with the first through holes and communicating with the recessed sections. The first, second, and third through holes, the recessed sections, and the vents communicate with each other to form back resonating chambers for the speakers.

  • Patent number: 8737671
    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.

  • Publication number: 20140016813
    Abstract: Low frequency alarm tones emitted by life safety devices are more like to notify sleeping children and the elderly. Disclosed herein is a life safety device equipped with a novel, compact, quarter-wave, folded resonant cavity which significantly increases the low frequency (400-700 Hz square wave) acoustic efficiency of an audio output transducer when the folded resonant cavity is acoustically coupled to the transducer forming an audio output apparatus. The folded resonant cavity is comprised of undulating, annular, acoustic passages to significantly reduce the length of the resonant cavity, thereby permitting the audio output apparatus to fit within the housing of conventional size life safety devices such as, but not limited to, residential and commercial smoke alarms and carbon monoxide alarms. Battery powered embodiments of the audio output apparatus comprising a folded resonant cavity passed audibility tests for low frequency alarm tones in smoke alarms specified by UL217.
