摘要： PROBLEM TO BE SOLVED: To provide a sound reproducing device capable of demodulating, reproducing a signal in an audible band with stable sound pressure in a wide frequency band. SOLUTION: In the sound reproducing device, a sound emission part includes: a plurality of resonance modes whose oscillation displacement becomes the maximum with different frequencies; and an ultrasonic wave oscillator capable of exciting oscillation to which mode coupling is performed between frequencies for exciting the plurality of resonance modes, and part of the frequency bands capable of exciting the oscillation to which the mode coupling is performed is made into a frequency of a carrier wave. Thus, the signal in the audible band output from an audible band signal source is demodulated, reproduced with stable sound pressure in the wide frequency band by making a frequency of the mode coupling with low rate of change in oscillation displacement to the frequency into a conveyance signal.

摘要： PROBLEM TO BE SOLVED: To solve the problem that a conventional AV reproduction apparatus comprises a screen on which an image is generated, and conical electromagnetic speakers disposed at both sides of or above and under the screen and such a configuration does not create any link between visual information on the screen and a generated sound. SOLUTION: An AV reproduction apparatus 1 comprises a visual display screen 11 and two or more transducer elements 13 arranged around the periphery of the screen 11 for generating an ultrasonic beam modulated with an audio-frequency signal. Non-linear effects in the air generate an audio beam propagating perpendicular to the screen. Such an integration of audio and vision may make the user feel as if the sound is being generated from the display screen 11 when he or she is watching the display screen 11, and also may project the sound towards a target user and seldom, or never, disturb unrelated persons. The ultrasonic transducer array may be made up independent transducer elements 13, or may comprise two or more sub-arrays of transducer elements. COPYRIGHT: (C)2007,JPO&INPIT
