    摘要： To provide audio reproduction technology by which audio data of high sound quality such as high-resolution audio can be reproduced with sound quality suited for background music (BGM).
    [Solution] A main control unit 18 sets an operation mode of a wireless audio player 1 to a normal mode or a BGM mode. When the operation mode of the wireless audio player 1 is set to BGM mode, an effect processing unit 16 subjects an audio signal that has been inputted from an audio reproduction unit 12 through a mode switching unit 17, the audio signal being a reproduction signal of audio data to be reproduced, to an effect process on the basis of music information of audio data to be reproduced as notified by a music information acquisition unit 14, and outputs the result from a speaker unit 13, the effect process including at least any one selected from dynamic range compression, high frequency and low frequency cutting, the addition of distortion, the addition of bubble popping noise, and a change in the reproduction pitch.

    摘要： A demodulation signal generator (14), coupled to an air-pulse generator (1) comprising a flap pair (102), includes a resonance circuit (140). The resonance circuit (140) produces a first demodulation signal (+SV) and a second demodulation signal (-SV). The resonance circuit (140) and the flap pair (102) co-perform a resonance operation, such that the first demodulation signal (+SV) and the second demodulation signal (-SV) are generated via the co-performed resonance operation and have opposite polarity. The flap pair (102) performs a differential movement to form an opening (112) to perform a demodulation operation on a modulated air pressure variation.

    摘要： An air-pulse generating device includes a first cell and a second cell. The first and second cells are disposed next to each other. Each cell includes a first flap and a second flap. The second flap of the first cell is disposed next to the first flap of the second cell. The first flap of the second cell is driven by a first demodulation-driving signal, and the second flap of the first cell is driven by a second demodulation-driving signal. A first transition period of the first demodulation-driving signal overlaps with a second first transition period of the first demodulation-driving signal.

    摘要： An air-pulse generating device includes a film structure including a flap pair. The film structure is actuated to perform a common mode movement, so as to form an amplitude-modulated ultrasonic air pressure variation with an ultrasonic carrier frequency. The film structure is actuated to perform a differential mode movement, so as to form an opening at a rate synchronous with the ultrasonic carrier frequency. The air-pulse generating device produces a plurality of air pulses according to the amplitude-modulated ultrasonic air pressure variation.
