Title:
PORTABLE BIOLOGICAL EMOTION REGULATION AND CONTROL APPARATUS AND METHOD USING AUDIBLE SOUND WAVES
Document Type and Number:
WIPO Patent Application WO/2023/124077
Kind Code:
A1
Abstract:
A portable biological emotion regulation and control apparatus using audible sound waves comprises a signal processing module, a signal modulation module, an audio power amplifier, and a loudspeaker array (3). The signal processing module is connected to the signal modulation module, the signal modulation module is connected to the audio power amplifier, and the audio power amplifier is connected to the loudspeaker array (3). The signal processing module processes an input signal to obtain a pre-modulation signal. The signal modulation module loads the pre-modulation signal onto a carrier by means of amplitude modulation to generate an amplitude modulation signal. The audio power amplifier performs power amplification on the amplitude modulation signal. The loudspeaker array (3) converts the amplitude modulation signal into an acoustic signal.
