    摘要： A security system and a method of determining whether there is an intrusion are provided. A correlation between sound signals obtained from a sound source generating device and a sound-field variation measuring device is used to measure a acoustic field in a certain space. A difference between an initially set acoustic field and a changed acoustic field is used to determine whether there is an intruding object in a certain space. The security system includes a sound source generating device for generating a sound source; and a sound-field variation measuring device for measuring a acoustic field formed by the sound source, wherein an initially set acoustic field is compared with the measured acoustic field to determine whether there is an intrusion.

    摘要： In a folding-type directional speaker array module, when sound is output, the directionality of a high frequency band can be obtained through a center speaker module and the directionality of a low frequency band can be obtained through side speaker modules unfolded from both sides of the center speaker module. Accordingly, the speaker array module has excellent directionality in an entire frequency band. Furthermore, the folding-type directional speaker array module has high mobility and portability because the side speaker modules are folded and stored when the folding-type directional speaker array module is not used.

    摘要： Provided is a forced acoustic dipole capable of regulating phases and acoustic pressures of first and second acoustic signals output from first and second pole speakers to freely steer the direction of an acoustic lobe. In addition, a forced acoustic multipole array is constituted by a plurality of forced acoustic dipoles. When the phases and acoustic pressures of the first and second acoustic signals output from the forced acoustic dipoles are regulated to steer an acoustic lobe in a specific direction, sound can be heard from a desired direction only without disturbing others.
