An in-plane position sensor detects positions along two directions or X-Y directions to produce a pair of position signals concurrently. The pair of position signals controls control parameters which influence upon a variety of effecters and addition processor which are implemented in a digital arithmetic unit (DSP).

A transformer 11, which converts input current into voltage output, is arranged between a power switch 1, which amplifies and outputs audio signals based on the power source voltage VDD supplied to MOS transistors Q1 to Q4, and a speaker 3. Through appropriately determining the turns ratio (Ns/Np), without causing the power source voltage VDD of the power switch 1 to be large, large voltage Vs is made to occur at both ends of the speaker 3 from such small power source voltage VDD. Through this, ...

An audio speaker including a chassis and a diaphragm defining an axis. A suspension movably interconnects the diaphragm and the chassis for reciprocating movement of the diaphragm along the axis. A motor is operably connected to the diaphragm for powered movement thereof. The diaphragm includes a cylindrical flange extending from its peripheral edges axially in the direction of the motor. The termination of said cylindrical flange provides an attachment for an annular rear flexible suspension me...

A dummy listener and right and left speakers 13 and 14 are disposed in an anechoic room as a model of the layout of those a car cabin 15 or the like. Transfer functions ALL, ALR, ARL and ARR in a space ranging from the speakers 13 and 14 to the right and left ears of a listener 16 in a car cabin 15 or the like are calculated from impulse response series aLL(t) to aRR(t) obtained when pulse sounds are respectively emitted from the speakers 13 and 14. A correction circuit 10b contains correction t...

A closure for a bottle. The closure includes an outer cap. An audio device and a triggering mechanism are positioned within the outer cap. A water block is positioned on the outer cap so as to prevent water from penetrating into the audio device.

There is provided an audio system which suppresses standing waves. An audio signal source (1) outputs audio signals (S.sub.R) and (S.sub.L) which are then supplied to reproducing loudspeakers (3) and (4),installed in a room (2), where the reproduced sounds are outputted. Furthermore, the audio signals (S.sub.R) and (S.sub.L) are added at an adder (9) to obtain signal (S2) which is in turn filtered by a compensating filter and then inverted by means of an inverting circuit (13). This generates a ...

An audio speaker is incorporated in a ventilation register having a front grill through which sound generated by the audio speaker is projected, and a back plate to which the audio speaker is secured, spaced apart from the front grill by side plates to form an enclosure adapted to be received in registration with the ventilation duct. The back plate includes at least one and preferably a plurality of ventilation slots offset from and surrounding the audio speaker for communicating an air flow be...

A method and apparatus for distributing audio signals from one of a plurality of audio sources to an output connect compressed audio signals from each one of the plurality of audio sources to an audio processor. Uncompressed audio signals are derived from the compressed audio signals. The compressed audio signal from one of the plurality of audio sources is selectively coupled to the output based upon the uncompressed audio signals. In a preferred embodiment, the compressed audio signal from one...

A high-fidelity (hi-fi) stereo speaker (110) having a three-sided pyramidal-like cabinet (112) with pyramid-like reflectors (118, 120) that reflect sound through openings (124, 126) in three sidewalls (122A, 122B) of the cabinet (112). The speaker (110) includes a tweeter (114) and woofer (116), and optionally a midrange (128) mounted in the cabinet (112) between the tweeter (116) and woofer (116). The tweeter (114) faces upward to reflect sound off one of the reflectors (118) that faces downwar...

The present invention provides a method for allowing a user's reading to dictate the speed and position at which content is converted to audio in an audio reader. The method includes determining a position of a user's eye gaze, identifying a content displayed at the position of the user's eye gaze, determining an audio corresponding to the content, and outputting the audio. The method of the present invention allows the user's reading to drive the text to speech conversion, resulting in the comp...
