An audio jack includes a casing 6 defining an interior space 620. Two sets of slots are formed on a top face 60 of the casing 6 in communication with the interior space 620 for receiving and retaining conductive terminal members therein, including two stationary members 3, 4 and two associated movable members 1, 2. The movable members 1, 2 engage with the stationary members 3, 4 and are selectively disengageable therefrom. The conductive terminal members 1, 2 3 and 4 are pre-compressed before be...

Audio processing apparatus comprises an audio processor operable to apply one or more processing operations from a set of audio processing operations to an input audio signal; adjustment controls for adjusting processing parameters associated with each of the set of processing operations; a display screen for displaying icons representing each processing operation of the set of audio processing operations; and a detector for detecting user operation of the adjustment controls associated with an ...

An audio jack comprises an insulative housing (1) defining a plug insertion hole (104) for receiving a contact of a plug connector, and a plurality of fixing terminals (2) and resilient terminals (3) received in corresponding receiving grooves (120, 140) in both sides of the housing. Each resilient terminal comprises a main body (30), a connecting portion (34) perpendicularly extending from the main body, a resilient arm (35) slantwise extending from the connecting portion round and away from th...

An audio apparatus comprises an internal clock capable of generating time data; a display section capable of displaying one form of information selected from several predetermined forms of information; and a controller capable of changing the selected information and enabling the selected information to be displayed on the display section, in accordance with the time data generated by the internal clock.

An identification code signal is hidden in a carrier signal (such as an electronic data signal or a physical medium) in a manner that permits the identification signal later to be discerned. The carrier signal can thereby be identified, or some machine responsive action can thereby be taken. The technique can be applied in video imagery embodiments to control associated video equipment, e.g. to serve as a copy control signal.

An input content signal--representing audio or video--is encoded to hide plural-bit auxiliary data therein. The process generates an intermediate signal that is a function of (a) the plural-bit auxiliary data, and (b) data related to human perception attributes of the content signal. This intermediate signal is then summed with the content signal to effect encoding. The plural-bit auxiliary data can include copy control data, i.e., data that can be sensed by a consumer electronic device and used...

An audio system includes a circuit (12) for processing an audio signal, this circuit (12) having an input (20) for receiving the audio signal and an output (26) for supplying an output signal. The circuit (12) further includes a harmonics generator (22) coupled to the input (20) for generating harmonics of the audio signal, and an adding circuit (24) coupled to the input (20) as well as to the harmonics generator (22) for supplying a sum of the audio signal and the generated harmonics to the out...

An audio connector comprises an insulative housing having a plug extending therefrom and defining a hole through a portion thereof adjacent to the plug, a U-shaped plate made of metal having a curved tab extending therefrom, and a metal shielding having an elastic tab beside which two slits are defined for providing deformation space for the elastic tab. The U-shaped plate is received in the housing from the hole thereof and the metal shielding is adapted to enclose the housing with the elastic ...

An audio system for a vehicle comprises an audio amplifier 14 and a manually adjustable volume control 18 for setting the output level of the sound generated by a loudspeaker 20 connected to the output of the amplifier 14. The amplifier 14 includes distortion sensing means for detecting when the level of distortion of the output signal of the amplifier 14 exceeds a reference threshold and a control circuit 16 reduces the sound output level of the amplifier in response to a signal from the distor...

An improved transducer which includes a rigid frame and a permanent ring magnet mounted to the frame. A small bobbin, preferably formed of aluminum foil, is sized and arranged to fit within the open end of the magnetic gap while permitting motion of the bobbin therein. A voice coil is wound on the bobbin and connectable to receive an audio signal, similar to a conventional voice coil driver system. A pair of flexible, curved diaphragms are disposed in the frame, generally free to move except for...
