An electro-mechanical vibration converter 14 is attached that converts an electrical signal into a mechanical signal and generates a bodily sensation of vibration. The audio signal source 10 includes an audio system (not shown), an equalizer 15, and a level compression circuit 16. The output terminal of the audio system (not shown) is connected to the input terminal of the equalizer 15, and The output terminal is connected to the input terminal of the level compression circuit 16, the output terminal of the level compression circuit 16 is connected to one end of the changeover switch 13, and the output signal of the audio system (not shown) is connected to the equalizer 15 and the level compression circuit. 16, and the signal control circuit 1 for bodily sensation vibration via the changeover switch 13.
This is what is output to 2. Pine surge signal source 1
1 is a low frequency oscillator (in this case, an oscillator that outputs 30Hz to 100Hz) 17 and an intermittent signal oscillator (in this case, an oscillator that outputs 0.1Hz to several Hz) 18
and a gate 19, the low frequency oscillator 17 outputs a signal for pine surge, and the intermittent signal oscillator 18 outputs a pine surge signal which is intermittently input to the sensory vibration signal control circuit 12. Gate 19
The function is to control the opening and closing of the series circuit from the low frequency oscillator 17 to the changeover switch 13 via the gate 19, depending on the level of the output signal of the intermittent signal oscillator 18, and to intermittent the pine surge signal of the low frequency oscillator 17. It is something that you have. The pine surge signal of the low frequency signal 17 can be switched to be inputted to the sensory vibration signal control circuit 12 as a continuous or intermittent signal by operating the changeover switch 13. The bodily sensation vibration signal control circuit 12 includes a vibration regulator 20, a low-pass filter 21, and a power amplifier 22. The vibration regulator 20 controls the vibration output generated by the electro-mechanical vibration converter 14. The input terminal is connected to the output terminal of the acoustic signal source 10 or the pine surge signal source 11 via the changeover switch 13, and the output terminal is connected to the input terminal of the low-pass filter 21. It is connected. The low-pass filter 21 selects and passes a signal corresponding to the bodily vibration from among the electrical signals from the acoustic signal source 10 or the pine surge signal source 11, and its output is input to the power amplifier. ing.

Changeover switch 13
When position B is set, low frequency oscillator 1
The pine surge signal output from 7 is sent to gate 19.
The electro-mechanical vibration converter 14 generates pine surge vibration by directly inputting it to the low-pass filter 21 via the changeover switch 13 and the vibration regulator 20 without going through it. In this case, since the output signal of the low frequency oscillator 17 does not pass through the gate 19, continuous pine surge vibration is obtained. When the changeover switch 13 is set to the C position, the pine surge signal from the low frequency oscillator 17 passes through the gate 19, so that the intermittent pine surge signal is input to the low pass filter 21.
The electro-mechanical vibration converter 14 generates intermittent pine surge vibrations.
