CPC A61N 2/02 (2013.01) [A61N 2/002 (2013.01); A61N 2/008 (2013.01)] | 9 Claims |
1. An apparatus for generating signal waveform for biological stimulation, comprising:
a signal input unit for inputting an external signal from an external environment;
a controller configured to generate and output:
a first biological stimulation signal wave that is
(a) frequency modulated by at least one of:
(x) a frequency component included in the external signal,
(y) an envelope component included in the external signal, and
(z) an amplitude component included in the external signal; and/or
(b) synchronized with an output timing of the external signal; and
a second biological stimulation signal wave based on the external signal;
a memory configured to store:
the external signal; and/or
the frequency component, envelope component and amplitude component included in the external signal;
a first coil for generating a high-frequency alternate magnetic field by feeding of the first biological stimulation signal wave;
a second coil for generating a low-frequency alternate magnetic field by feeding of the second biological stimulation signal wave; and
a haptic output unit comprising at least one of a speaker configured to output the external signal as a sound and a display configured to output the external signal as an image, wherein the first coil and the second coil overlap with each other viewed along an axis of the first coil and an axis of the second coil, the high-frequency alternate magnetic field is in a range of 30 MHz to 300 MHz, the low-frequency alternate magnetic field is in a range of 1 kHz to 3 kHz, and features of the waveform of the low-frequency alternate magnetic field are applied to the waveform of the high-frequency alternate magnetic field.
