This realizes a state where the exciter film is pulled outwardly with respect to the secured ends due to bending stresses therein. If sound-releasing driving signals are applied to the piezoelectric films in this state, the exciter film contracts and expands along with the expansion and contraction of the piezoelectric films, thereby causing the oscillation plate to oscillate. | 2015-05-14 |
20150131824 | METHOD FOR HIGH QUALITY EFFICIENT 3D SOUND REPRODUCTION - A method for spatial sound reproduction from a first audio input signal includes using a plurality of loudspeakers using a plurality of virtual loudspeakers over which the first audio input signal is panned for forming second audio input signals using source positioning data and virtual loudspeakers positioning data. The virtual loudspeakers are synthesized by modifying second audio input signals forming third audio input signals using virtual loudspeaker spatial filter coefficients that align the loudspeakers. The method includes the steps of extracting equalization filter coefficients using source positioning data and modifying the first audio input signals using equalization filter coefficients | 2015-05-14 |
20150131825 | AUDIO OUTPUT CONTROL METHOD AND APPARATUS - An audio output control method and apparatus using a wired/wireless communication system is provided. An audio output control method of an audio output device connected to at least one other audio output device according to the present disclosure includes converting specific audio data to at least one modified audio signal designated to the respective audio output devices, playing at least one of the modified audio signals through a channel designated to the specific audio data, and transmitting a remaining of the modified audio signals to the at least one other audio output device, wherein the modified audio signals include at least one of sound sources and channel characteristics of the specific audio data. | 2015-05-14 |
