摘要： A loudspeaker device having an improved reproducing capability in a range of low audio frequencies owing to ensuring a large size and area of the vibrating plate, an increased output sound pressure, and vibrating points (signal control points). Input signals Vin are inputted through independent channels, calculation and addition of an interference eliminating signal for eliminating interference between signal control points are performed, calculation and addition of an acoustic interference signal for interfering the outputs from the signal control points with each other in an arbitrary point are performed, so that an acoustic signal processing unit (30) inputs the signal inputs Vin into a transducer (20) attached to a vibrating plate (10). The transducer (20) transduces an electric signal to mechanical vibration. Signal control points are provided on the vibrating plate, and each control point causes the plate (10) to vibrate. If such a vibrating plate (10) made of a transparent material is attached to a display, the display screen can be used as a loudspeaker device.

摘要： A signal regulator (50) regulates an auxiliary signal (A) based upon a primary signal (P') scaled by an external amplifier. The signal regulator (50) receives the primary signal with an unscaled level (P). Processing circuitry (54) monitors the unscaled level of the primary signal. The primary signal (at 56) is then output to the external amplifier for scaling, either by amplification or attenuation. The primary signal with a scaled level (P') is fed back to the signal regulator (50) from the amplifier. The processing circuitry (54) monitors the scaled level of the primary signal (P') from the amplifier, and then generates a gain factor (G) based upon the unscaled level (P) and scaled level of the primary signal (P'). An auxiliary signal (A) is received by the signal regulator (50). Adjusting circuitry (62) adjusts a level of the auxiliary signal based upon the gain factor (G). The auxiliary signal with the adjusted level (A') is then provided to an external component, for example, a loudspeaker.

摘要： The electronic audio connection system of the present invention provides an experience much like sharing a room with several involved parties, even though the parties are physically separated. Speech enhancement and speech emphasis processing functions ensure parties perceive the speech captured in the audio signals, typically the most important portion of the captured audio signals. To capture audio signals, each space is provided a plurality of microphones (112) arranged in that space so that the sum audio signal captured by the microphones enables the creation of a sharable audio space. Each separate physical space transmits (116) its captured audio signals to a central server (104) via a bi-directional data communications medium. The central server (104) processes the summed audio signals and in turn transmits playable audio signals to each separate physical space. Speakers (110) located in each separate physical space aurally transmit the playable audio signals. This creates an audio space shared by each of the active separate physical spaces.

摘要： A spectacle-stereo headphone combination (20) for connection to a portable personal music player which is stylish, convenient to use and technically suitable for real-life conditions. Embodiments which permit complete removal of the earphones (24, 26) provide a direct connection to the music player for one earphone through a plug (56, 58) which also connects to a jack (66) in one of the temple pieces (30, 32). Internal wiring passes through the temple-pieces (30, 32) and brow portion to a jack (66) in the other temple-piece which is plug-connected to a cable (54) for the other earphone. In one embodiment in which the earphones are captive, a single stereo cable is connected to the music player and to internal wiring in the spectacle frame (22) to provide connections to the two earphones (24, 26). The earphones (24, 26) are designed for storage in molded elastic inserts housed in recesses in the temple-pieces (30, 32). The recesses are open at the back so the earphones (24, 26) may be released simply by pushing out on the back of the insert. In a variant of this embodiment, an elastic head band is permanently attached to the temple-pieces. The wiring is provided by cables which pass through a channel in the head band and are directly connected to the earphones. The cables extend from and retract into the head band to permit convenient positioning of the earphones for use and storage. In another captive embodiment, the earphones are designed for storage behind the ear, and are pivotally mounted on telescoping arms which emanate from each temple-piece.
